Posted on by 3 comments

Here at LSOZI, we take off every Wednesday for a look at the old steam/diesel navies of the 1833-1954 period and will profile a different ship each week. These ships have a life, a tale all their own, which sometimes takes them to the strangest places. – Christopher Eger

Above we see USS Winder (PCS-1376), the leader of her class of 89 very interesting Patrol Craft, Sweepers, seen in a World War II image, likely while on coastal escort out of Miami in 1944-45.

You’ll note that, although she is only 136 feet long overall, she is very well armed with both twin Mousetrap ASW rocket racks and a 3″/50 DP mount forward, four 20mm Oerlikon singles amidships, a 40mm Bofors aft, four depth charge projectors, and two depth charge racks over her stern.

These criminally forgotten little patrol boats went on to serve a myriad of roles in the Cold War.

Meet the 1376s

With the British 105-ft Admiralty-type motor minesweepers (MMS) making a good impression on the U.S. Navy– after all, the Royal Navy ordered more than 300 of those hardy 295-ton wooden coastal mine hunters from 1940 onwards and used them for everything from gunboat to light salvage in addition to their mine warfare roles– the idea of a PCS seemed a good one to the Americans.

With wooden hulls to counter magnetic influence mines, the 105-ft Admiralty-type motor minesweepers were very successful– and easy to make by small commercial shipyards. Here a 105, Motor Minesweeper J 636, is underway in British coastal waters. IWM A 14421

Whereas the Admiralty 105s typically only carried a few Oerlikons in addition to their sweep gear and acoustic hammer, the Americans needed something with longer legs and, they felt, a lot more firepower. As described above, they got it with a mix of 3-inch, 40mm, and 20mm guns as well as the capacity to carry as many as 50 depth charges to feed their racks and K-guns.

Plus, there was Mousetrap.

The Mk 20 Mousetrap anti-submarine rocket system is both loaded/ready to fire and stowed on a similarly sized PC. The projectiles were 7.2 inches in diameter and weighed 65 pounds with an explosive charge of 31 pounds. Unlike the Hedgehog weapon, the Navy classified the projectile as a rocket, as it utilized propellant that burned for 0.2 to 0.7 seconds.

They carried an SF-1 type radar (some later fitted with more advanced SO-1 or SU-1 sets) and a QHA sonar set (later upgraded to the more mine-sensitive FM sonar in some ships).

First fielded in 1942, the SF-1 was a 10cm 150 kW surface search radar good out to 16nm. Here, USS PCS-1389 is seen on 12 December 1944, showing an updated SO-1 radar antenna. NH 64671

Simple and cheap, their engineering suite consisted of a pair of General Motors 8-268A diesel engines, generating 800hp, using Snow and Knobstedt single reduction gear, turning two shafts. This enabled a top speed of 14 knots but meant the cruising speed was still in the 12-13 knot range.

Constructed by firms as diverse as the Burger Boat Co of Manitowoc, Tacoma Boat, Western Boat in Tacoma, Astoria Marine Construction Co., Bellingham Marine Railway & Boatbuilding Co, Wheeler Shipbuilding of Long Island, Robert Jacob Shipyard in the Bronx, Greenport Basin & Construction Co in Connecticut, W.F. Stone & Son Shipyard in Alameda, and the Gibbs Gas Engine Co of Jacksonville, these warships could be made fast and without tying up a lot of precision slipways or using tough-to-source material.

Our class leader was laid down on 13 October 1942 as PC-1376 at Wheeler on Long Island, soon reclassified to PCS-1376 while still under construction, and commissioned on 9 July 1943.

As befitting an overgrown armed yacht built on Long Island, her skipper was LT J. P. Morgan III, USNR, (Harvard 1940), the great-grandson of robber baron J. Pierpont Morgan and son of Junius Spencer Morgan III– the latter at the time an OSS officer. Along with three other officers (two ensigns and an LT jg) and 54 enlisted, they provided PC-1376‘s first crew.

Check out the rates, for those curious, as seen in the ship’s war diary:

Her first ammo draw from Iona Island on the Hudson River included 296 3-inch shells (270 service, 16 target, 2 practice, 8 dummy), 1,784 40mm shells (1760 service, 16 target, 8 dummy), 2,800 rounds of .45 for the Tommy guns and M1911s in her small arms locker; and 1,800 rounds of .30 caliber for her M1903A3 rifles. This did not include depth charges, Mousetrap bombs, and 20mm ammo.

The class leader had a rather boring war career, being ordered for duty as a school ship at the Submarine Chaser School located in Miami after she completed her shakedown. She would spend the rest of the war there, alternating between use as a training bot and in coastwise patrol, riding shotgun on convoys from Miami to Cuba and back.

But our story is about all the 1376s.

The rest of the class…

A baker’s dozen became Control Submarine Chasers (PCSC) almost as soon as they were completed. This conversion was simple, removing the 40mm mount to allow a radio shack to be built. In this role, they could better control swarms of inshore landing craft headed toward the beach.

A sort of mini amphibious command ship.

This was detailed by the NHHC further in its coverage of the Iwo Jima landings:

The Iwo Jima operation provided the first test of the amphibious forces’ newly formed permanent control organization. This organization was established following the Marianas campaign, where it was realized that proper control of the ship-to-shore movement of the amphibious craft had become a continuing 24-hour-a-day task, requiring specially trained control personnel and specially equipped control vessels.

The control organization for the Iwo Jima operation consisted of the Transport division, Transport Squadron, and Central (Amphibious Group or Force) Control Officers, permanently assigned to the staff of their respective commanders. This organization now parallels the echelons of both the beach party and the shore party. Control officers were embarked in the same ships as their opposite number in the beach and shore party, giving the maximum amount of time for coordination and understanding of each other’s problems prior to the landing.

Each control officer was provided with a control vessel (PCE, PCS, PC, or SC) which had been previously equipped with special communication facilities and provided with a control communication team and advisors from the troops. The control vessels were obtained and equipped, and the personnel were trained in their specialized duties, well in advance of the operation. As a result, for the first time the task of controlling the ship-to-shore movement, both during the assault and unloading phases, was handled by a “professional.” In addition, the control-equipped craft was provided to the different troop staffs for use as floating command posts.

Another 33 became Auxiliary Motor Minesweepers (YMS), renumbered YMS 446-479. This involved landing most of their ASW weapons and loading up on the sweeping gear.

Some managed to get some real trigger time in, for instance, USS PCS-1379 participated in the invasion of Peleliu and Angaur Islands, shelled Japanese targets on Eil Malk and in the Abappaomogan Islands, then saddled up for the Okinawa campaign.

PCS-1391 took part in the Leyte and Lingayen Gulf operations in the Philippines, serving as a landing craft direction vessel. Then at Okinawa, she carried Maj. Gen. Pedro del Valle, the Commanding General of the First Marine Division, to the beach during the initial assault landings.

PCS-1452 participated in operations at the Marianas, Saipan, Tinian, Iwo Jima, and Okinawa. She had lots of company, as no less than 10 of her class were present at the latter two operations.

YMS-481 (exPCS-1462) was lost to Japanese shore batteries off Tarakan, Borneo, on 2 May 1945.

PCS-1396 was damaged off Okinawa by a Japanese Kamikaze but would shrug it off and continued serving until 1949.

PCS-1407, PCSC-1418, PCS-1440, PCS-1454, PCS-1461, and YMS-472 were lost to the September-October 1945 Typhoons Ida and Louise off Japan and Okinawa.

PCS-1435 was present in Tokyo Bay during the Japanese surrender ceremony in September 1945.

PCS-1445 would serve with the 7th Fleet for the last ten months of the war then spend another eight months as the harbor entrance control vessel for the Yangtze River at Shanghai.

Some would serve in the Korean conflict as mine hunters, with PCS-1416 for instance clearing a channel more than 60 miles inland from the Yellow Sea and up the Taedong River to Chinnampo.

Catching names

Oddly, while many were laid up in the 1950s, they picked up a series of names, typically those of small towns. This non-inclusive list shows some of the variety. Sadly, many of these towns have never had another warship named in their honor.

  • Provincetown (PCS 1378)
  • Rushville (PCS 1380)
  • Attica (PCS 1383)
  • Eufaula (PCS 1384)
  • Hollidaysburg (PCS 1385)
  • Hampton (PCS-1386)
  • Beaufort (PCS 1387)
  • Littlehales (AGSC 7, ex-PCS-1388)
  • Deming (PCS 1392)
  • Sanderling (MHC 49)
  • Dutton (AGSC 8, ex-PCS-1396)
  • Coquille (PCS 1400)
  • McMinnville (PCS 1401)
  • Elsmere (EPCS 1413)
  • Swallow (MSC[O] 36)
  • Prescott (PCS 1423)
  • Verdin (MSC[O] 38)
  • Conneaut (PCS 1444)
  • Waxbill (MHC 50)
  • John Blish (AGSC 10)
  • Medrick (AMc 203)
  • Minah (MHC 14)

Shifting duties and designations

Postwar, besides utility work, many became naval reserve training vessels, with their shallow draft allowing them to be stationed well inland. For example, PCS-1423 was stationed at Vicksburg, Mississippi, and PCS-1431 in Louisville.

Louisville, KY, 1958, U.S.Navy sub chaser USS Grafton (PCS 1431) passing 

Their designations often shifted to Coastal Minesweepers (AMc), or Motor Minesweepers (AMS) in the late 1940s, designations they carried until they were decommissioned and struck.

Another quartet became Coastal Surveying Ships (PCS-1388, PC-1396, PC-1404, and PC-1457 became AGSC 7/8/9/10).

Three of the ships, PCS-1393, PCS-1456, and PC-1465, would be reclassed no less than four times as a YMS, then an AMS, then a Coastal Minesweeper Underwater Locator (AMCU), and finally a Coastal Minehunter (MHC)– carrying five different pennant numbers in 12 years.

PC-1413 and PC-1431 would be reclassified as Experimental Patrol Craft Sweepers (EPCS).

At least three picked up the curious designation of Coastal Minesweeper, Old (MSC(O)).

By this time, their fit had changed significantly, shedding most of their guns and Mousetrap devices in lieu of a large Hedgehog ASW device forward (which it was thought could also prove effective in minefield destruction).

Moving on…

While some were disposed of by scrapping as soon as 1947, the Navy would look to transfer others to allies and other missions.

One, PC-1458, served both as a Navy survey ship (AGS-6), in 1944, then was transferred to the Coast and Geodetic Survey in 1948 as USC&GS Derickson, serving until 1954.

Two other ships of the class, PC-1405 and PC-1450, were also transferred to the survey and named USC&GS Bowie (CSS 27) and USC&GS Hodgson (CSS 26), respectively. Bowie served until 1967 when she was scrapped, and Hodgson was transferred the following year to South Korea for further service.

USC&GS Bowie (CSS 27) (bow visible at left) and USC&GS Hodgson (CSS 26), circa 1965. NOAA photo

One, PCS-1425, was transferred by the WSA to the Puget Sound Naval Academy in 1947 to serve as a training vessel. At the same time, PCS-1445, formerly of the Yangtze squadron, went to Texas A&M.

As with any WWII-era American warship smaller than a heavy cruiser, several were transferred to the Allies as Lend Lease.

The Russians got a full dozen PCSs in 1945 which were active well into the late 1950s, serving as dive boats, degaussing ships, as well as mine vessels. Unlike most larger vessels, these were never repatriated.

Three were handed over to the Philippines at Subic Bay post-war as military aid (USS PCS-1399, USS PCS-1403, and PC-1404) and served into the late 1960s.

The Japanese got one (PCS-1416) while the South Koreans picked up five (PC-1426, PCS-1428, PCS-1443, PC-1445, and PCS-1448) and continued to use them into the 1970s. Meanwhile, Turkey got PCS-1436.

The end game

January 1958, left to right: ex-Rushville, ex-Deming (PCS 1392), and two unidentified PCS’/YMS’ at Mare Island awaiting transfer to civilian buyers.

The last in Navy inventory was McMinnville (PCS 1401), placed out of service and struck from the Naval Register in August 1962. Sold the next year to a group of treasure hunters in south Florida, she remained in the Keys as a yacht for another 20 years.

Ex-USS Prescott (PCS-1423) ashore after its towing vessel, the fishing craft Sea King, struck a rock jetty at Barnegat Inlet, New Jersey, and sank in February 1963. The Prescott had just been purchased from the Navy at Brooklyn, New York. She was later pulled free and, converted to a trawler, and would remain active into the 1980s. UA 455.12

Others were bought up at auction by fishing companies and converted to that life, bumping around with nets and dredges as late as the 1990s, often under Caribbean nation or Panamanian flags. 

One, ex-PCS-1438/YMS-470/AMS-37/MSC(O)-37, was bought by General Motors in 1959 and used as a corporate yacht in California, then was acquired by Windjammer Cruises to operate as the M/Y Royal Taipan out of Hawaii. She was famously almost lost at sea in 1990.

As for class leader Winder (PCS 1376), she was decommissioned after the war in February 1947, used for a time as a Naval Reserve training vessel at Norfolk, then was laid up in Florida where she was struck in 1957 and sold. Her ultimate fate is unknown. I’d like to think that she is still out there somewhere in some sort of low-pressure use. 

As far as I can tell, there are no surviving PCS-1376s afloat and they left behind few relics to prove they even existed, save for some war diaries in the National Archives.

Ships are more than steel
and wood
And heart of burning coal,
For those who sail upon
them know
That some ships have a
soul.

Above we see the unpresuming Navajo/Cherokee/Apache-class fleet tug USS Tawasa (AT-92) departing Subic Bay bound for Haiphong in February 1973 to take part in Operation End Sweep. Don’t let her workaday appearance fool you, launched eight decades ago today– 22 February 1943– she saw more hairy situations than many battleships across her 32-year career and helped boil the sea.

A new type of tug, for a new type of war

With the immense U.S. Naval build-up planned just before WWII broke out, the Navy knew they needed some legitimate ocean-going rescue tugs to be able to accompany the fleet into rough waters and overseas warzones. This led to the radically different Navajo/Cherokee class of 205-foot diesel-electric (a first for the Navy) fleet tugs.

These hardy 1,250-ton ships could pull a broken-down fleet carrier if needed (Tawasa would prove that in 1965) and had long enough sea legs (10,000 miles) due to their economical engines to be able to roam the world. Armed with a 3″/50 caliber popgun as a hood ornament, a matching pair of twin 40mm Bofors, and some 20mm Oerlikons, they could down an enemy aircraft or poke holes in a gunboat if needed.

In all, the Navy commissioned 28 of these tough cookies from 1938 onward, making a splash in Popular Mechanics at the time due to their impressive diesel-electric power plant consisting of a quartet of GM 12-278A diesels driving four GE generators and a trio of GM 3-268A auxiliary services engines, generating 3,600shp.

Their war was hard and dangerous with 3 of the ships (Nauset, Navajo, and Seminole) meeting their end in combat, and the 25 that made it through the crucible going on to serve in other conflicts, and under other flags.

The Cherokee/Navajo class would prove successful enough that 22 follow-on tugs– with the same hull form and engineering plant but with a re-trunked exhaust that shrunk the funnel diameter– of the Abnaki class would be constructed during the war, and two (Wateree, lost in a 1945 typhoon; and Sarsi, sunk by a mine off Korea in 1952) lost in Navy service. 

Meet Tawasa

The hero of our story, USS Tawasa (AT-92) was laid down on 22 June 1942 at Portland, Oregon, by the Commercial Iron Works, a small firm that would crank out no less than 188 hulls for Uncle Sam during the conflict ranging from landing craft to escort carriers. Tawasa’s launch date, some 80 years in the rearview, saw her sponsored by Mrs. Thomas F. Sullivan, the tragic gold star mom of the five lost Sullivan brothers.

The first U.S. Navy vessel named for a Florida branch of mound-building Muskhogean Indians subsequently named the Apalachicola tribe, she commissioned on 17 July 1943, just under 13 months after her first steel was cut.

WWII

Following her shakedown cruise off California, Tawasa was assigned to Service Force, Pacific Fleet, and left Pearl Harbor in early November, bound to spend Thanksgiving 1943 in the Gilbert Islands, which were being taken by Marines.

Christmas saw her in Tarawa and the New Year of 1944 with TF 52 pushing through the Marshall Islands, where she lent a hand in the landings at Kwajalein, Majuro, and Eniwetok, at times pinch-hitting as a destroyer acting as a screening vessel with her overheating and cranky WEA-2 sound equipment in the water. Her ASW armament if she had a contact? Just eight “ashcan” style depth charges on two short gravity racks over her stern.

As noted by DANFS:

Off Kwajalein Atoll on the 31st [of January], Tawasa took soundings enabling Mississippi (BB-41) to approach the shore for close bombardment. The tug then performed salvage, towing, and screening duty until 18 February when she moved to Eniwetok to assist in the assault that was to strike that atoll the next morning. She supported operations until the atoll was secured and remained in the area for almost two months, providing services to American ships using this new base.

Tawasa’s War Diary for 30/31 January 1944:

Continuing with TF52, she would soon be assisting combat-loaded LSTs landing Marines and gear on Saipan in June.

With the Marianas wrapping up, by late July Tawasa would be reassigned from TF52 back to ServRon, South Pacific, and placed on a series of unsung missions. She became particularly adept at pulling LCIs off the beach. Her embarked divers came in handy when it came to recovering lost anchors and chains, along with conducting submerged inspections of recently captured ports and leaky hulls, while her DC teams would often fan out to weld 1/4-inch steel sheeting over holes in the side of battle damaged landing craft. Her 20-ton derrick boom allowed her to salvage all manner of objects from the seafloor. Meanwhile, her sonarmen and radar operators would keep their eyes and ears peeled for interloping enemy aircraft and vessels of all types.

The Japanese surrender found our tug in Guadalcanal, where she had just transported military passengers from the Russell Islands. Post VJ-Day, she remained forward deployed except for a trip stateside to California and would operate in Chinese and Japanese waters well into 1947.

In the end, Tawasa would earn three battle stars for her WWII service.

Korea

While a wide variety of brand new ships wound up in mothballs in the days after WWII– some being towed to red lead row right from the builders’ yards– these fleet tugs remained on active service. No rest for the working man.

The Cherokee class fleet tugs listed in the 1946 Jane’s, Tawasa included. Note that the list includes the Abnaki-class half-sisters as well.

Alternating between Alaska and Guam in the late 1940s and early 1950s, Tawasa was deployed to the 7th Fleet to serve in the Korea conflict, assigned alternatively to the ports of Cho Do, Sokcho, and Chinghai while under the control of TF 92 from July 1952 through January 1953. In this, she added two further battle stars to her salad bar.

Returning stateside, she spent six months in overhaul at the San Francisco Naval Shipyard. When she emerged in November 1953, a terrific series of images were captured of her for the U.S. Navy Bureau of Ships files, detailing her radar (SO-4), radio, and overall fit. If you are a modeler looking for shots of a 1950s Cherokee class tug, the National Archives has you covered with this series:

Wigwam

Fielded in 1952 without full-scale war shot tests, the 500-pound Mark 90 “Betty” nuclear depth charge was seen as an ace-in-the-hole against rapidly growing fleets of schnorkel-equipped Soviet Whiskey-class submarines, of which Moscow ordered a staggering 215 in four different versions (Projects 613, 640, 644, and 665) between 1949 and 1958.

Carrying a W7 Thor tactical fission bomb with a theoretical yield of up to 30 kilotons– twice the force of the Hiroshima bomb– it was thought that a single Betty dropped via a patrol plane would be enough to clear out a whole nest of Whiskeys.

But the Navy wanted to be sure the theory held.

Enter Operation Wigwam, a full-scale test of a live device.

Conducted in May 1955 some 500 miles southwest of San Diego in water 16,000 feet deep, Tawasa tugged a Betty as part of a six-mile long towline that included a trio of identical white-painted 4/5-scale submarine hulls (704 tons, 140 foot long with a 20-foot beam complete with correct bulkhead spacings to spec and 1-inch HST steel hull plating) dubbed “Squaws” which were filled with instruments. 

The three Squaw submarine mock-ups generally mimicked the same hull construction techniques as seen on the Navy’s SS-563 (post-war Tang) class diesel GUPPY boats, which were at least as strong if not stronger than Soviet Whiskey boats. The targets were fitted with extensive seismography instruments at 52 locations spread throughout their compartments.

With the Squaws submerged at a depth of 250-290 feet at three different distances from the device, the Betty was rigged some 2,000 feet under the keel of its support barge and the Wigwam task force beat feet to observe from five miles away.

The resulting “hot” bubble from the submerged blast grew to over 4,600 feet across when it broke the surface and rose some 1,900 feet above the water at its height.

Squaw 12, the closest to the device, simply disappeared.

Here is the view from five miles out. Hydrophones at Point Sur, Hawaii heard the “thump” of Wigwam from 2,500 miles away. NARA 374-ANT-30-30-DPY-11-20

The gist of the 56-page after-action report on the squaws:

The external pressures applied to the three SQUAW targets in Operation Wigwam were measured with pressure gages, and the deformations of the hull were measured with strain and displacement gages. The results indicate that SQUAW-12 was at a horizontal range of 5150 ft and a depth of 290 ft the peak shock pressure at the hull was about 850 psi and the target was destroyed, probably within 10 msec. SQUAW-13 was at a horizontal range of 7200 ft and a depth of 260 ft the peak dynamic pressure at the hull was about 615 psi, and the hull was probably near collapse but did not rupture. The estimation is that the lethal horizontal range of the SQUAW target under the Wigwam test conditions is about 7000 ft for a depth of 250 ft and about 4500 ft for a depth of 70 ft.

Even though at least 362 personnel of the task force’s 6,732 men embarked– clad just in working gear with no flash or NBC protection– would have mildly dirty dosimeters after the event, and contaminated water was found at several depths during the weeks following the test, it was judged that Betty was safe-ish enough to be used under certain conditions, and was more than capable of sinking an enemy sub (or three) within a two-mile radius of its impact if used correctly.

This 11-minute film covers the test in great detail, including Tawasa and her six-mile squaw-laden towline.

Betty would remain in service until 1960 when it was replaced by the multipurpose B57 nuclear bomb during the mid-1960s. In its depth charge variant, the hydrostatic fuzed B57 had a selectable yield up to 10 kt– only about one-third of the Wigwam device– and could be dropped by P-3s, S-3s, and SH-3s as well as the short-lived Drone Anti-Submarine Helicopter (DASH). It was thought that in most scenarios, the B57 depth charge would only be dialed in at 5 kt. It would finally be withdrawn in 1993.

Anyway, back to our ship.

Vietnam

Dusting off and cleaning up post-Wigwam, Tawasa would continue to serve with the 7th Fleet on WestPac deployments, including four to Vietnam (May-Oct 1968, April-Sept 1969, May-Sept 1970, and Feb-June 1972). For this, she would earn seven Vietnam-era campaign stars.

Her most notable moments during this era included the largest operational tow made by a solo tug of the Pacific Fleet: 33,946 tons, when she pulled the decommissioned USS Bunker Hill (AVT-9) from San Francisco to San Diego, and coming to the rescue of the shattered destroyer USS Frank E. Evans (DD-754) which had been sheered in two by the Australian aircraft carrier Melbourne during Southeast Asian Treaty Organization exercises in the South China Sea.

Tawasa took the remaining stern section in tow and returned it to Subic Bay.

She closed out her Vietnam service with Operation End Sweep off Haiphong in 1973. During the six months of End Sweep, 10 ocean minesweepers, 9 amphibious ships, 6 fleet tugs, 3 salvage ships, and 19 destroyer types operated in RADM Brian McCauley’s Task Force 78, sweeping hundreds of the aircraft-laid mines.

By 1973, she was one of 25 of her class still in Navy service but her days were numbered.

Jane’s 1973-74 listing, in which the class is dubbed the Apache class. Note that the list includes the Abnaki-class half-sisters as well.

Epilogue

With a final scoresheet that would include three battle stars for World War II service, two for Korea, and seven for Vietnam, Tawasa was decommissioned and struck from the Navy list on April Fool’s Day 1975. She was sold for scrapping the following August.

There has not been a second Tawasa on the Navy List.

Much of her logs and photos are in the National Archives.

As for the rest of her sisters, many continued in U.S. Navy service until as late as the 1970s when they were either sunk as targets or scrapped. A number went as military aid to overseas allies in Mexico, Colombia, the Dominican Republic, Indonesia, and elsewhere. One sister, USS Apache (ATF-67) who served as the support tender for the bathysphere Trieste, was transferred in 1974 to Taiwan and continues to serve as ROCS Ta Wan (ATF-551). Added to this is USS Pinto (AT-90), which has been in Peru as BAP Guardian Rios (ARB-123), and USS Sioux (AT-75), which lingers as the Turkish Navy’s Gazal (A-587).

The final Abnaki-class half-sister in the Navy’s inventory, ex-USS Paiute (ATF-159), was stricken in 1995 after 44 years of service spanning WWII, Korea, Vietnam, and the First Gulf War, then scrapped in October 2003 at Portsmouth.

The legacy of U.S. Navy fleet tugs is kept alive by NAFTS, the National Association of Fleet Tug Sailors. The only Navy tug museum ship is the former ATA-170-class auxiliary tug USS Wampanoag/USCG Comanche, which will be opened to the public in the coming months.

When it comes to Betty, the National Museum of the U.S. Navy has an inert casing on display, noting, “After tests at sea and in the Nevada desert, the Navy soon determined that the Mk 90 was not a practical weapon and retired the system in 1959.”

Ships are more than steel
and wood
And heart of burning coal,
For those who sail upon
them know
That some ships have a
soul.

May we all grow up to be Buzz Aldrin

Downing a pair of NorK MiG-15s while flying an F-86 Sabre as part of the famed 51st Fighter Wing over Korea would be the highlight of a career for most, but was just the opening act for Buzz…

Col. Edwin Eugene Aldrin Jr., (USMA 1951), besides flying 66 combat missions during the Korean war, shooting down two enemy MiG-15s, making three spacewalks as pilot of the 1966 Gemini 12 mission, serving as the lunar module pilot on the 1969 Apollo 11 mission where he was the second man to walk on the surface of the moon– and pack later a punch to defend that honor— just made his 93rd orbit around the sun while aboard this humble rock in style.

On my 93rd birthday, and the day I will also be honored by Living Legends of Aviation, I am pleased to announce that my longtime love and partner, Dr. Anca V Faur, and I have tied the knot. We were joined in holy matrimony in a small private ceremony in Los Angeles, and are as excited as eloping teenagers.

The oldest surviving moonwalker (only 4 of the 12 remaining) got hitched in combat boots, no less. 

Clowns and Mills Bombs

Posted on by One comment

78 years ago today, 23 January 1945: PVT Marcel St-Laurent of “D” Company, Le Régiment de Maisonneuve, clowns for the camera at Cuyk, Netherlands. Details of the fuze on the bottom of the No. 36 Mills Bomb grenade can be seen. The length of the cloth bandolier has been altered by tying a knot in it to make it shorter.

First introduced in May 1918 and updated in the 1930s, the No. 36M Mk I was the British Army’s standard hand grenade until 1972 and still pops up in Africa and the Middle East from time to time.

A Canadian UN soldier in Korea with a U.S. made M-1 Carbine and several British Mills bomb grenades.

As for the good PVT St-Laurent, the Montreal-recruited Régiment de Maisonneuve was first recruited in 1880 and covered itself in glory in both World Wars– where its members became well-acquainted with the Mills Bomb. When the top image was taken, the regiment had previously landed in France in July 1944 as part of the 2nd Canadian Infantry Division. It was bled white through the Battle of the Scheldt, and the Walcheren Causeway before reforming for the final campaigns in the northern Netherlands and the Battle of Groningen.

It endures to this day as a Primary Reserve unit, still based in Montreal, along with the better-known “Van Doos” of the 22nd Regiment, making up one of the few French-language units of the Canadian forces.

The Flight to Freedom’s final chapter

Posted on by Leave a comment

We pause to remember a North Korean fighter pilot today, No Kum-sok.

Born in 1932 as Okamura Kyoshi in the Japanese-occupied Hermit Kingdom, he was the son of a baseball player. The teen considered becoming a kamikaze during the latter stages of WWII but was dissuaded from it and nonetheless later became an aviator for the Korean People’s Air Force.

Training in Manchuria under his new, more Korean name, he would complete no less than 100 combat sorties in the Korea War. Just after the truce was announced, and with his father dead and his mother in the West, he decided it was time to pull stumps for the South.

At the stick of his advanced MiG-15bis, he would famously streak from Sunan outside of Pyongyang to Kimpo Air Base in South Korea on 21 September 1953, a flight of just 17 minutes, and become probably the highest-profile defector of the day.

After being debriefed by the CIA, he was given $100K as authorized by Operation Moolah, although he was not aware of the reward for defectors who brought their MiGs over.

1.2 million of these pamphlets were dropped on North Korea in 1953. Operation Moolah promised a $100,000 reward to the first North Korean pilot to deliver a Soviet MiG-15 to UN forces, or just $50K for either a pilot or aircraft. The pamphlet carried the photo of LT Franciszek Jarecki, who had flown his Lim2 (license version of MiG 15bis) from Poland to political asylum in Denmark in March 1953.

Taking the name Kenneth H. Rowe, he emigrated to the U.S.– where his mother had already escaped to– and, picking up several engineering degrees and a Korean-American bride, worked in the American aviation community and then as a professor at Embry-Riddle. Mr. Rowe, late of the DPRKAF, passed in Florida over the weekend, aged 90.

As for his MiG, following a career as a test aircraft in USAF custody, it was sent to the National Museum of the U.S. Air Force, where No visited it before his death. It has been restored to its original #2057 livery. 

Ping! Happy 90th Birthday, Garand Patent

Posted on by Leave a comment

On 27 December 1932, the U.S. Patent Office granted Case File No. 1,892,141, for a “Semi-Automatic Rifle” to one John C. Garand, aged 44 of Massachusetts. The rest is history.

The 75-page patent application filled out and filed by Mr. Garand himself is so historical that it is fully digitized in the U.S. National Archives.

Filed in April 1930, it was endorsed by the Secretary of War with W.N. Roach, the Army’s Chief of the Patent Branch of the Ordnance Department, signing the drawing sheets and application forms as Garand’s attorney of record. His address was simply listed as Springfield Armory.

Among the most captivating pieces of the application were several pages of diagrams, all of which are suitable for framing in any man cave.

Toughest thing I had to write

Posted on by One comment

This cartoon hit me in the feels this year.

That’s because it is the first in my life without my grandfather.

A career NCO (Signal Corps), he joined the Guard as a teenager during the war in Korea and then transitioned to active service, serving as an adviser to the Shah’s Army, to that of the King of Iraq, to the West Germans, and then the South Vietnamese, the latter repeatedly. After traveling around the globe for most of his 23 years of active duty, he retired as a promotable E8, declining to take the extra bump and be a 30-year man because it would have meant finishing his next contract in the Beltway, something he said that he just wasn’t built for.

So, he retired, picked up his family from Fort Gordon, then headed back home to Mississippi. This included his newly-born first grandson– me.

My grandpa and I in 1975, just after he left the Army, with his brand new bouncing baby grandson. The carpet on the wall behind him he brought back to the states from some bazaar in Iran, back when it was called Persia. The right is him just last year, a proud old bearded Vietnam vet.

Now, he is gone, and, while I have written professionally for the past 20 years, including several books, thousands of articles, and thousands more blog posts, his obituary was the toughest thing I ever had to write.

Over 8.7 million Americans served in the Armed Forces during the Vietnam era from 1964 to 1973, and it is thought that well over a third of those have already left us, with more packing their sea bags and duffles every day. The number of Korean War era Vets is even smaller and is expected to fall below 200,000 in the next couple of years.

Be sure to hug them while you can.

So I went to see Devotion…

Posted on by 2 comments

I weighed in last week on the behind-the-scenes attention to detail of the new J. D. Dillard/Erik Messerschmidt Sony Pictures war biopic Devotion, focusing on the too-short life of Ens. Jesse Leroy Brown and his “Fighting Swordsmen” wingman, Lt. (j.g) Thomas J. Hudner Jr., who flew side-by-side at the Battle of Chosin Reservoir in the Korean War.

If you missed that, the production went all-out, leasing real MiG-15s, F4U Corsairs, A-1 Skyraiders, and F8F Bearcats, then constructing an Essex-class straight deck carrier in a field to put them all on for static shots.

I mean, Dillard is the son of a Blue Angel and his first memory is touching the nose of his dad’s just-landed F-18– so what do you expect?

Said the director on his use of these vintage war birds:

It was by far the most meticulous part of the filmmaking process, but it was important to me aesthetically that we put as much realism in front of the camera as we could. There aren’t even enough of these period planes still flying to fill the skies in the way that we wanted to. But what we always prioritized is that the action happening closest to the camera was practical. That 17th plane, half a mile off, can totally be CGI. But the plane flying very close to the camera is a real Corsair painted with the real squadron’s letters and numbers, and there are real stunt pilots in those planes, executing real maneuvers. That was very important to me and ultimately worth the prep and the planning.

And, besides tapping in actor Glen Powell– who played the cocky “Hangman,” the modern Iceman substitute in the new Maverick movie– Dillard also used the same aerial photography team that worked on that project but with the benefit of fewer restrictions.

“I joke that they spent 200-plus million dollars on R&D, then came to work with us,” Dillard says. And since his film didn’t use modern U.S. Navy planes, he had more freedom. “There is significantly less red tape when you want to take that plane 15 feet over the water at more than 100 miles an hour and photograph it, which at one point we did,” he says. “There are also technical differences in photographing those aircraft… As a small example, you can’t put a camera directly behind an F-18, because there’s jet blast. But we could sit our camera plane right on the tail of the Corsair because it has a propeller — you’re not worried about the camera melting from the afterburner.”

With this lead-up, how could I NOT go see the movie on opening night last week?

I can report that it was a good film, that should be seen on the biggest screen possible to drink it in, full of amazing and unique warbird shots. As far as the plot, it is based on a true story and they stick to most of the real details with only minor deviations. The dialog was a little hokey at times but certainly not any worse than that seen in other modern war films.

As Brown was the first African-American U.S. Navy officer killed in action, he has long deserved a decent film telling his story and this is it. Going past that, it is entertaining and, while circling back to the racial elephant in the room several times, doesn’t make it the prime driving point of the film. I’m no movie rater but if you had to ask me, I’d give it at least an 8 out of 10 overall.

If you have some time to kill, you could find worse ways to spend two hours.

Perhaps it will lead to Brown getting a destroyer named after him. 

Speaking of which.

Welcome home, Hudner

Of interest, the SURFLANT-tasked Flight IIA Arleigh Burke-class destroyer USS Thomas Hudner (DDG-116), commissioned in 2018, just returned this weekend from the inaugural deployment of the Gerald R Ford Carrier Strike Group.

As detailed by the ship’s social media page:

-We sailed 15,148 miles,
-Conducted 7 replenishments at sea,
-Set 8 Sea and Anchor details
-Completed 2 Straits Transits
-Saw winds as high as 52 knots,
-Completed 78 flight quarters,
-Inducted 4 new Chief Petty Officers,
-Qualified 3 new Officers of the Deck, 2 new Tactical Action Officers, and 8 new Engineering Officers of the Watch
– Expended 52,266 rounds of ammo,
– Passed 1 Engineering Certification,
– Visited 2 new countries,
And made countless memories along the way.

    Mighty Mansfield

    Posted on by Leave a comment

    56 Years Ago Today: Sumner-class destroyer USS Mansfield (DD 728) letting rip her 5″/38 DP Naval Guns at water-borne craft off the coast of North Vietnam, north of the demilitarized zone.

    Photographed by PH1 V.O. McColley, November 25, 1966. USN photo 428-GX-K-35025.

    Named for Marine Sergeant Duncan Mansfield of circa 1804 “Shores of Tripoli” fame, Mansfield (DD‑728) was laid down 28 August 1943 by the Bath Iron Works and commissioned just short of eight months later on 14 April 1944.

    Earning five battle stars in the Pacific– including downing 17 Kamikazes in one day off Okinawa and later taking part in a daring high‑speed torpedo run with DesRon61 into Nojima Saki, sinking or damaging four enemy ships — she witnessed the formal Japanese surrender ceremony in September 1945 in Tokyo Bay.

    Picking up a further three battle stars for Korean service while almost breaking her back on a mine off Inchon, Mansfield would be FRAM II’d in 1960, trading in her WWII kit for Cold War ASW work, and ship off for the 7th Fleet.

    Rotating through four deployments off Vietnam between 1965 and 1969, she also had enough time to serve as an alternate recovery ship for Gemini XI (and slated for the Apollo 1 mission).

    Her Vietnam “Top Gun” Results, 1965-69:

    • 5″ Rounds Fired: 40,001
    • Days on Gun Line: 220
    • Times Under Hostile Fire: 8
    • Enemy KIA: 187
    • Active Artillery Sites Silenced: 30
    • Secondary Explosions: 59
    • Structures/Bunkers Destroyed: 495
    • Ships/Junks/Boats Sunk: 224

    Decommissioned on 4 February 1971, Mansfield was disposed of and sold to Argentina on 4 June 1974 where she was mothballed at Puerto Belgrano and scavenged for spare parts to support that country’s other American surplus tin cans, then was eventually cut up for scrap in the late 1980s.

    Whistling up an Essex class carrier and matching Corsairs

    Ensign Jesse L. Brown, USN. In the cockpit of an F4U-4 Corsair fighter, circa 1950. He was the first African-American to be trained by the Navy as a Naval Aviator, and as such, he became the first African-American Naval Aviator to see combat. Brown flew with Fighter Squadron 32 (VF-32) from USS Leyte (CV-32). Official U.S. Navy Photograph, now in the collections of the National Archives. USN 1146845.

    This week is the opening of the J. D. Dillard/Erik Messerschmidt Sony Pictures war biopic Devotion, focusing on the too-short life of Ens. Jesse Leroy Brown and his “Fighting Swordsmen” wingman, Lt. (j.g) Thomas J. Hudner Jr., who flew side-by-side at the Battle of Chosin Reservoir in the Korean War.

    The obligatory trailer:

    And, from the Navy, Dillard and Glen Powell (who portrays Hudner) talk about the importance of maintaining historical accuracy while filming, which pulled in vintage Corsairs and F8F Bearcats from around the globe and the construction of a 1:1 scale CV-32 deck/island in a field in Statesboro, Georgia.

    Nice they aren’t totally CGI!

    As Brown was a Hattiesburg native Mississippian, his deeds have long been remembered at the Mississippi Military History Museum at Camp Shelby and the African American Military History Museum in Hattiesburg. The latter has a life-sized Brown standing on the deck of the USS Leyte.

    It is great that this story is finally getting some bigger exposure.

    In a deeper dive into the story overall, USNI host Eric Mills sits down with Thomas Hudner III, son of the real-life MOH recipient depicted in Devotion.
