Hunter Killers!

Below is a great 1967 film featuring Grumman S-2E Trackers of Sea Control Squadron Twenty Four (VS-24) Scouts and VS-27 Pelicans and Sikorsky SH-3A Sea King helos of HS-3 Tridents from Carrier Antisubmarine Warfare Group Fifty Six (CVSG-56) aboard USS Randolph (CVS-15).

Also featured in the film are S-2Es of VS-28 Gamblers and VS-31 Topcats and SH-3As of HS-11 Sub Seekers from CVSG-52 aboard USS Wasp (CVS-18). Other footage of S-2Es of VS-22 Checkmates and VS-32 Maulers and SH-3As of HS-5 Nightdippers from CVSG-54 aboard USS Essex (CVS-9) is also used in the film. Grumman C-1A Trader carrier onboard delivery (COD) aircraft and Grumman E-1B Tracer airborne early warning radar aircraft of various VAW-33 Nighthawks detachments also appear in the film. The destroyer USS Newman K Perry (DD-883) is the only identifiable escort in the film but several DDs are shown from a distance.

Scratching that Unterseeboot itch from the air

While 765 German U-boats were lost by all causes in WWII, one of the leading was due to Allied air attacks, especially after late 1942. Here are a few of the losses that made the photo gallery.

80-G-323977 Operation Torch, November 1942. An aerial attack on a French submarine off the coast of French Morocco. I’m not sure which one of the Vichy subs this is as two were lost during the battle with the Diane-class submarine La Sybille lost at sea on 8 November and the L’Espoire-class submarine Le Tonnant was scuttled off Cadiz 15 November as result of battle damage.

80-G-208592: German U-boat, U-849, attacked and sunk by a U.S. PBY-1 Liberator (navalised B-24) aircraft from VP-107 in the South Atlantic, West of Congo estuary. The pilot shown here is Lieutenant Junior Grade Vance Dawkins, USNR. Incident #5054. U-849, a long-range Type IXD2 U-boat was splashed 25 November 1943, lost with all hands. Official U.S. Navy Photograph, now in the collections of the National Archives.

80-G-222832 U-271, a German a Type VIIC, being sunk off Ireland by a Liberator aircraft of VB-103 on 28 January 1944 in the Northwest Atlantic. Incident #5430. While a member of both the Rügen and Hinein Wolfpacks, and a participant in three patrols, U-271 did not achieve any kills.

Go for a ride on a Boomer

The Navy just released this really great 11-minute doc about life aboard the Ohio-class ballistic-missile submarine USS Wyoming (SSBN 742) as she takes part in a regularly-scheduled patrol in the Atlantic Ocean. Entitled “On Our Depth One-Six-Zero Feet” it is sure to become a classic in future generations and is notably devoid of rah-rah-rah, simply giving the viewer a “fly on the wall” experience.

Commissioned in 1996, the motto of the Kings Bay-based Trident slinger is Cedant Arma Toga, “Force must yield to law”

Sure you have a drone, but does your drone have a drone?

Complete with lots of dramatic royalty free muzak, the above video from Lockheed-Martin is actually pretty interesting if you take the time to digest it.

It shows “Vector Hawk,” a small, unmanned aerial vehicle (UAV), on command from the little yellow submarine looking thing– “Marlin MK2” autonomous underwater vehicle (AUV)– while a third vehicle, the “Submaran,” an unmanned surface vehicle (USV) developed by Ocean Aero (the sailboat looking thing), provided surface reconnaissance and surveillance.

As noted by LM:

The four-pound Vector Hawk can fly for 70-plus minutes, at line-of-sight ranges up to 15 kilometers. Operators can recover and re-launch the Vector Hawk in a matter of minutes (including changing the system’s battery). Vector Hawk is built on an open architecture to enable rapid technology insertion and payload integration.

Marlin MK2 is a battery powered, fully autonomous underwater vehicle that is 10 feet long with a 250 pound payload capacity, 18-24 hour endurance, depth rating of 1000 feet and weighs approximately 2,000 pounds. Its open architecture design and modularity allow new mission packages to be quickly integrated into Marlin to meet emerging customer needs.

Warship Wednesday, June 7, 2017: The first stripe and the savior of the Queen

Here at LSOZI, we are going to take off every Wednesday for a look at the old steam/diesel navies of the 1859-1946 time 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

Warship Wednesday, June 7, 2017: The first stripe and the savior of the Queen

Here we see an oncoming Coast Guard Cutter through an attack periscope of a “U-boat.” She is the Owasco-class gunboat/high endurance cutter Androscoggin (WPG/WHEC-68) and was the first to carry the now-customary racing stripe of the service. More on this submarine action below.

The word Androscoggin is an Indian term meaning “fishing place for alewives” or “spear fishing” and is used for a river formed on the Maine-New Hampshire border as well as a county and lake in the same area. The name was first used in U.S. maritime service by the U.S. Revenue Cutter Androscoggin, a 210-foot vessel built for the service in Delaware in 1908.

USRC Androscoggin (1907-1922) at the dock at Boston Navy Yard, MA, May 14, 1920. The wooden planking of the hull can clearly be seen. NHC S-553-K

One of the first warships (she was armed with a quartet of four pounders as well as demolition charges and mines to sink deflects found at sea) designed to break ice, she was used in many high-profile rescues at sea under amazingly harsh conditions as well as participating in the early International Ice Patrol after the loss of RMS Titanic. In 1914, she interned the North German Lloyd Line steamship SS Kronprinzessin Cecilie— with $10m worth of German gold aboard– as the Great War came to Europe and saved her from likely capture by British ships on the Atlantic– a fun point when we consider the follow-on Cutter Androscoggin.

Speaking of which, let’s get to the 255-foot Owasco or “Indian tribe” -class.

Designed during World War II to replace a few elderly cutters dating back to the 1900s as well as 10 Lake-class vessels transferred to Britain in 1940 under the Destroyers for Bases deal, the 13 Owascos were short (225 feet) and beamy (43 feet) making them as wide as a FFG7 class frigate of today but about 200 feet shorter. With a displacement of over 2,000-tons at full load, they were wider and as heavy as a Fletcher-class destroyer of the day but classified as gunboats (PGs) by the Navy.

They were the most heavily armed Coast Guard ships of WWII, with twin 5″/38 mounts fore and aft, a pair of quad 40mm Bofors, 4x20mm/80 singles, twin depth charge racks over the stern, 6 Y-gun depth charge projectors, and a Mark 10 Hedgehog anti-submarine mortar device. Besides the larger Wind-class icebreakers operated by both the Navy and the Coast Guard, and the 327-foot Treasury-class cutters, the Owascos were the only WWII-era ships built for the service that had a fire control radar (a Mk26). The initial design even included an amidships floatplane and catapult, but this was deleted.

With their overly complex turbo-electric plant and low-speed (17 knots wide open), these boats were not really meant for high seas/heavy weather but for close-in littoral (16-foot draft) work and plodding convoy operations.

Androscoggin’s sister, the 255-ft. U.S. Coast Guard Cutter ESCANABA, based in New Bedford, Massachusetts, takes a salty shower bath in rough North Atlantic weather on ocean station ‘Delta’, 650 miles southeast of Newfoundland and east of Nova Scotia

The first 11 of the class were built by the Western Pipe & Steel Company at San Pedro, California, while the last two—Mendota and Pontchartrain—were completed at the hands of the by the Coast Guard Yard at Curtis Bay, Maryland. None made a significant impact on WWII, with class leader Owasco commissioning on 18 May 1945.

CGC Androscoggin, the last of the class built at San Pedro and the last of the design to be completed, commissioned on 26 September 1946, a full year after the war ended. Her first station was in Boston where she spent until 1950 on weather stations in the Atlantic, sans most of her wartime armament.

Original caption states: “The U.S. Coast Guard Cutter ANDROSCOGGIN (WPG-68), shown here leaving port bound for Argentia, Newfoundland, the ANDROSCOGGIN has served primarily as an Ocean Weather Stations vessel in the North Atlantic. Circa 1950; no photo number; photographer unknown. Note the appearance of her contrasted against the Oswasco’s WWII armament and camo.

Transferred to Miami in 1959, Androscoggin would spend the next 23 years off and on there conducting law enforcement and search and rescue operations, as well as occasional stints on ocean weather station tours– the latter spent performing 28 days obtaining meteorological and oceanography data and information. As such, she had her sole twin 5″ mount replaced with a more practical single tube.

Androscoggin also helped support the Navy’s Fleet Sonar School in Key West, serving as the USCG’s school ship there on occasion. During this time, she spent a lot of hours in war games with the various WWII Balao-class subs stationed in the Keys, and as such her sonar and electronics were updated from 1940s-era sets to the current fleet standard.

Original caption states: “The 255-foot U.S. Coast Guard Cutter ANDROSCOGGIN, stationed at Miami, Fla., as a training and search and rescue ship, is now carrying specially trained U.S. Weather Bureau observers to gather upper-air weather information during her patrols in the Gulf of Mexico. The ANDROSCOGGIN makes many training cruises a year and performs search and rescue work in the South Atlantic and Gulf. In connection with law enforcement, she patrols the Campeche Banks, and are of fishing grounds off the town of Campeche in the Gulf used by hundreds of fishing vessels of the United States and Mexico.”; 13 August 1958; Photo No. 5821; photographer unknown.

During the Cuban Missile Crisis in 1962, she chopped to help the Navy, picking up the Navy Expeditionary Medal.

In 1965, Androscoggin was the first in the service to pick up the USCG’s new “racing stripe” design.

A Technicolor close up of her stripe in 1966 with a bone in her mouth. Note the design has changed over the years in respect to the shield and its placement. Also, note the .50 cal and Hedgehog just under the bridge windows.

In 1966, she was detached to the Bahamas where she helped support the filming of the Paramount film “Assault on a Queen” in which Frank Sinatra and company salvage a lost German U-boat and use her to stop and rob the RMS Queen Mary.

As noted by the Coast Guard’s Historian’s Office: “In the final segments of the film, Androscoggin, through the miracle of special effects, saves the day by ramming and sinking a renegade submarine, thereby thwarting Sinatra’s dastardly plan to rob RMS Queen Mary on the high seas.”

Many of the ocean scenes in the filming of “Assault on a Queen” took place in the huge man-made pool that was the “Sersen Tank” at Fox’s Ranch in Malibu Canyon. Built in the 1960s, dozens of films from “Cleopatra” to “Tora! Tora! Tora!” had their water scenes shot there. The Sinatra crew’s static U-boat set was built there and the footage of Androscoggin‘s ice-strengthened bow rushing from the horizon as the German skipper fires his P-38 in the last act of defiance was superimposed.

Her movie days behind her, she was sent to war.

In 1967, Androscoggin was dispatched to the Navy’s control again, heading to Vietnam for a nine-month stint in Operation Market Time, the interdiction effort off the coast of that country to stop reinforcements from the North from making their way south via water. Androscoggin was assigned to Coast Guard Squadron Three, Vietnam, from 4 December 1967 to 4 August 1968, ditching most of her remaining ASW gear for a pair of 81mm mortars (used for firing illumination rounds) and a half-dozen M2 .50 cals for keeping small boats at bay.

(At least the hammer on the 1911 is down) “A captured Viet Cong from the morning’s raid by the junk force and 82-footer is guarded while his companion is undergoing surgery aboard the Andy in a futile attempt to save his life for further interrogation.” US Coast Guard Cutter ANDROSCOGGIN Deployment in Viet-Nam; Nov. 1967–Sept. 1968 [Cruise Book], page 86.

In addition to sinking or destroying 106 enemy sampans, on the night of 28 Feb/1 March 1968, Androscoggin shot it out with a large armed North Vietnamese steel-hull trawler moving munitions down south at the mouth of the Song Cau River.

During her 304-day mission from Miami to Miami, she steamed 64,676 miles and fired 4,147 5-inch shells from her main gun over the course of 44 naval gunfire support missions– some with as little as three feet of brackish water under her keel. Her crew also investigated over 2,000 surface contacts, conducted 17 medical missions ashore and delivered four babies.

In her 27-years afloat, she played host to several crew members who went on to great things. Roland Hemond was an NCO on “Andy” in the 1950s and played on her softball team before going to become one of baseball’s most successful executives, spending 23 years as a general manager with the Chicago White Sox and Baltimore Orioles before becoming the chief executive officer of the Arizona Diamondbacks.

The well-liked and respected 23rd Commandant of the Coast Guard, Adm. Thad Allen (USCGA 1971) was a newly minted 22-year-old ensign on Androscoggin when it came to his duty to file the customary New Year’s Eve Log going into 1972 as the ship sat tied up at Miami Beach, and I think it is one of the better than I have read:

Such as I, on numbered ships,
on many nights, for countless years,
Have toyed their minds in search of words
To describe a mooring to some pier;
Or the loneliness out underway,
Remembering gentle words and tears,
And find some clever way to state
The movements of a thousand years.
So I, like them, with pen in hand
Here on these pages now commit
The status of our weather ship
And the varied functions there, to wit.
Our mooring lines run two by two
Secured are we this year so new
Berth, Foxtrot, to which our hawsers reach
Is to our port in Miami Beach.
Commander, Coast Guard District Seven
Sits above us in the heavens.
He gives us orders and transfers souls
And exerts his operational control.
Since airplanes in the foremast look pretty unsightly
All of our lights are burning brightly.
To wet our throats and light our way
Throughout these Charlie-status days
Upon the dock we must rely
For telephone and shore ties
So we may protect those here inside
We have sit Yoke modified
And to insure this ship stays sound
The messenger is making hourly rounds.
Pollution abatement is the Coast Guard’s pride
But we are pumping our sewage over the side
And last, there are those more lucky than we
In duty section one, two and three
For to keep the wolf away from the door
The duty belongs to section four.
While at home with family and fireside bright
The commanding officer is ashore tonight.
…with duties done and entries made,
I can only sit and ponder
The pathways through the coming year
And courses we must wander.
Ours is such and duty calls,
But the day must come for us to see
The people of the Earth walk hand in hand
And all nations are one and free.
Until that time we all will pray
That we may find each other
Then stop the wars that mean our doom
And walk the Earth as brothers…
Few creatures are stirring to see the year slip,
Brow quite wrinkled and dark eyes set deep
Love, peace, and joy are there to be found

With the Coast Guard’s post-Vietnam draw-down and a dozen new Hamilton-class 378-foot cutters joining the fleet, the 13 Owascos were retired en bloc between 1973-75, with Androscoggin decommissioned on 27 February 1973, and sold for scrap on 7 October 1974. Few reminders of the class remain.

Androscoggin‘s memory is maintained by a dedicated group of former crewmen and her log books, going all the way back to 1947, are in the National Archives.

There is this piece of maritime art, “Weather decks secure” by CDR Don Van Liew, of Androscoggin at sea.

You can always watch Assault on a Queen, from which stock footage of Androscoggin has been recycled into a number of 1960s and 70s TV shows.

And of course, the racing stripe lives on…and is now the standard identification for coast guard vessels around the world under dozens of flags.

Even the Russians Coast Guard uses it!

Warship Wednesday, May 31, 2017: The Swordfish of the Baltic

Here at LSOZI, we are going to take off every Wednesday for a look at the old steam/diesel navies of the 1859-1946 time 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

Warship Wednesday, May 31, 2017: The Swordfish of the Baltic

Image via Saab Defense, who own Kockums.

Here we see the ubåt HSvMS Svärdfisken (Sf) of the Royal Swedish Navy (svenska flottan) as she appeared in 1914 on builder’s trials from Kockums before delivery to the fleet.

The cool kid stuck sitting in the Baltic between the knuckle-cracking bruisers that were the Kaiser’s Germany and the Tsar’s Russia, Sweden faced the problem of being able to keep her sea lines of communication open while appearing to be too tough a nut to crack should either one of the class bullies decide to come sniffing around. This meant innovative coastal battleships and submarines.

While Sweden counted among her illustrious sons no less a person than early U-boat pioneer Thorsten Nordenfelt who sold cranky early submarines to Turkey and Greece, the country went shopping elsewhere for some more mature designs.

The first Swede ubåt, the stubby single-hulled HSvMS Hajen (Shark) was built at Bergsunds Mek. Verstad in Stockholm in 1904 under the eye of former USN engineering officer and MIT graduate Carl Eric Richson (himself a Swede) and, at 111-tons and 77-feet oal, would be considered a midget sub today. She carried a single 450mm bow tube and could make 9.5-knots wide open.

Next were a series of three locally built “bathtub” boats of the same size as Hajen built in 1909, followed by a narrow and sexy Italian sub, HSvMS Hvalen (Whale) of some 140-feet, built at Fiat-Laurenti of San Giorno in 1912. While Hvalen was nice, had a double-hull, and could touch 14-knots, the spaghetti boat also had leaky gasoline engines that were prone to catch fire at the most inopportune times.

This brings us to the decision in 1913 by the Swedes to contract with Kockums Mek. Verkstads AB of Malmo to build the first modern all-Swedish combat submarines, the Svärdfisken (“Swordfish,” Kockums hull No. 115, Swedish Navy pennant “Sf”) and Tumlaren (No. 116, pennant “Tu”) while the near-sister Delfinen (“Dolphin,” pennant “Df”) was laid down at Bergsunds Mek. Verkstad.

A modification of the Fiat-Laurenti design of Hvalen, these 300-ton boats had a long, narrow pressure hull and went 148-feet overall. Gone were the gasoline engines, replaced by a pair of Swede Jonas Hesselman’s forward-thinking 500 hp diesels which charged batteries for two Luth & Rosén electric motors on twin shafts. On the surface, they could make 14.2-knots, submerged 9.5. The difference between Delfinen and the two Kockums-built craft was that she carried a different set of diesels that generated 450 hp each (good for 13.2kts) and a slightly modified single hull design.

The vessels’ 21-man crew operated a pair of 450mm torpedo bow tubes with four “fish” carried as well as a low-angle M98 37mm deck gun kept very greasy to help abate salt-water corrosion.

The class was designed from the ground up to use wireless sets, which at the time were so new as to almost be considered a novelty.

Note the double periscopes

All ships of the class could dive to 110-feet, which was sufficient for use in the shallow waters of the Baltic– and they could float in 11 feet of seawater and operate at a periscope depth of 25 feet. The crews trained to spend upwards of 24 hours at a time submerged, most of it stationary.

Note her deployed high mast which incorporated a wireless antenna. As with the image above, her deck gun has not been fitted yet.

When the Great War kicked off and Germany and Russia began to duke it out on the regular whenever the Baltic ice allowed it, all three of the new Swede swordfish were operational and spent much of their time at sea enforcing Swedish neutrality at the force of a torpedo tube and deck gun– stepping up the latter to a 57mm Bofors piece after Armistice Day. This early cold war often turned hot, with a Swedish submarine on at least one occasion taking fire from an armed German trawler.

The two Kockums-built boats were reportedly popular with their crews and had an enviable safety record, a feat that was often elusive with pre-WWI designs.

The three sisters alongside tender in 1917, the elderly 1870s 175-foot iron-hulled steam gunboat HSvMS Skäggald (Bearded Eagle)

Then came the salad days of the Swedish Navy’s submarine force.

By 1929, the King’s ubat fleet counted the 3 Svardfisken, 2 Laxen-class, 2 Abborren-class, 3 Hajen-class, 3 Bavern-class, HSvMS Valen, and 3 Draken-class vessels giving the force a total of 17 modern hulls. When you take into account the Germans were forbidden by the Versailles Treaty to operate/maintain U-boats, and the Soviets’ Red Banner fleet was still crippled by the Great War/Revolution/Civil War and remained that way until the early 1930s, Sweden had more operational submarines in the Baltic than anyone else.

And it would only get stronger, as in 1933 a program to build a dozen new 200~ foot subs, each with a six-pack of 21-inch tubes, were ordered. This, of course, led to the withdrawal of some older designs.

While the cranky Delfinen was scrapped in 1930, Svärdfisken and Tumlaren had their names struck (and recycled for new submarines) and were placed in reserve in 1936 to continue to serve as pierside trainers.

Still in reserve when the next war came but working with hulls considered too unsafe to submerge and take into combat, both Kockums-built boats were used as floating AAA batteries along the Swedish coast during World War II. For this, they landed their old low-angle 57mm deck gun and fitted a few 40mm Bofors and light weapons.

All the Svärdfisken-class were scrapped by 1946, with the set-aside Bofors 57mm deck gun (Ubåtskanon) of Svärdfisken retained and placed on public display at the Swedish Marinmuseum.

As mentioned above, the Svärdfisken and Tumlaren had their names given to new Sjölejonet-class ubats commissioned in 1940. These vessels remained in the fleet through WWII and the Cold War until 1959 and 1964 respectively.

Since the production of Svärdfisken, Kockums has produced no less than 73 submarines, with the latest being the Gotland-class and pending A26s, which, while sharing many traits of the old Swordfish (small, shallow divers) are still some of the most innovative and deadly in the world.
