Why a flexure arm matters in a pistol red dot…

SIG debuted the closed emitter Romeo M17 – which, as its name would imply, is built from the ground up as a near “bomb-proof” red dot for the military’s M17 and M18 Modular Handgun System pistols – earlier this year. Constructed of forged 7075 aluminum with a beryllium copper flexure arm (more on that in a minute) the Romeo M17 has an extremely low deck height so that armorers can reuse standard iron sights, has 15 illumination settings (including three for use with Gen 3+ night vision), beats drop and submersion tests, and, importantly, has an integral loaded chamber gas deflector shield that keeps the MHS from gassing up the lens after 10-15 rounds.

The sight has been spotted in military use, it has been submitted to the Army’s Soldier Enhancement Program, it has an NSN number, and SIG tells us a large public safety contract announcement is soon to break on the optic as well.

The Romeo M17 is a hoss. This installed example I saw dropped from 10 feet onto concrete at SIG’s plant in Oregon earlier this year with nothing but cosmetic damage to the housing. SIG explained to Guns.com that the Romeo M17 has surpassed 100,000 rounds in testing without loss of zero or parts breakage. (All photos except noted: Chris Eger)

Part of what makes the Romeo M17 so tough is an innovative beryllium copper flexure arm that replaces springs with a much more robust part – which adds to durability – and helps drop the deck to allow a better co-witness with standard iron sights.

That magical Romeo M17 flexure arm.

Installed near the base of the Romeo M17, the arm provides a backbone – so to speak – for the sight, cutting down on the number of parts that can fail.

The problem is, the Romeo M17 uses a unique mounting footprint, one that has six leverage points and uses 40 pounds of torque with a single optics plate mounting screw. In short, unless you have an M17 or M18 military or commemorative handgun, you can’t mount it.

That’s where the Romeo X comes in.

Mad Fox Buzzing Moscow

A Cold War classic!

Official caption: “4 March 1970. U.S. Navy anti-submarine warfare aircraft P-3A Orion, from the “Mad Foxes” of Patrol Squadron FIVE (VP-5), she flies in the vicinity of the Soviet helicopter carrier ship Moskva (841). The number designation roughly fits with the date of this photograph. She was primarily an anti-submarine warfare ship.”

Dubbed a helicopter cruiser (kreyser-vertolotonosets) in Russian service, Moskova, Soviet designation Project 1123 Kondor, was the country’s first operational aircraft carrier. Commissioned Christmas Day 1967, the 15,000-ton flattop could carry as many as 18 helicopters in addition to a pretty significant battery of ASW and air defense weapons. She outlived her only completed sister (Leningrad) and was kept in service until 1996. Following the end of the Cold War, she was quietly retired and scrapped without ceremony.

Meanwhile, VP-5, founded in 1937, is still around, now flying the P-8A Poseidon. Their motto is “No Fox Like a Mad Fox!”

Danish keeping it flexible

The Royal Danish Navy has, for the past few decades, really been hitting it out of the park in terms of low-cost, flexible, and multi-function patrol frigates. One that allowed ASW, AShM, and MCM modules that could be added or swapped out as needed. You know, what the LCS was supposed to be.

The Flyvefisken and Thetis classes are to the left, and the newer Knud Rasmussen class offshore patrol vessels and Absalon and Iver Huitfeldt-class frigates are to the right. Via Breaking Defense

Besides the small 400-ton Flyvefisken-class patrol vessels with their innovative containerized weapon systems (again, what the LCS was supposed to be), the Danes also produced the excellent follow-on Thetis-class ocean patrol vessels, small 3,500-ton 368-foot surveillance frigates that were good for an 8,700nm cruising rang on an economic diesel plant while carrying a light gun-only armament (although ASMs could be fitted) while being able to carry a Marine platoon and an MH-60 sized helicopter. Plus, they did this with just a 40-50 man complement.

A good recent primer on how the Thetis class is used is in the below 11-minute video from NATO, showcasing the HDMS Triton (F358).

This comes as the Danes are looking towards the new OMT MPV80 program to develop a replacement for these arctic patrol frigates.

These are about as modular and multifunctional as it gets, as befitting the third generation of Danish LCS. 

Warship Wednesday, July 19, 2023: Red Sub Circumnavigator

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

Warship Wednesday, July 19, 2023: Red Sub Circumnavigator

Above we see the type IX-bis S (Stalinets) class “medium” Guards Red Banner submarine S-56 returning to Polyarni in early 1944 from a patrol off the coast of German-occupied Norway. The most celebrated of her class, she claimed one of her biggest “kills” some 80 years ago today.

The S-class

It is a little-known fact that the Tsarist Imperial Navy entered the Great War in 1914 with more submarines in its inventory than anyone else. Following the national disaster that was the Russian Revolution and Civil War, the reformed Red Navy inherited a few of these old boats and even managed to keep some of them in operation into the 1950s!

When it came to new designs, by the late 1920s the Soviets built a half dozen modest 1,300-ton Dekabrist-class (Series I) submarines constructed with Italian expertise, followed by 25 minelaying Leninets-class (L class, or Series II) submarines of the same size which were essentially reverse engineered from the lost British L-class submarine HMS L55 which was recovered by the Soviets, and a staggering 88 Shchuka-class (Series III, V, V-bis, V-bis-2, X, X-1938) “medium” submarines that went some 700 tons and were ideal for use in the cramped Baltic and Black seas.

Then, the Stalinets class in IX, IX-bis, IX-bis-II, and XVI series, began to appear in 1936.

Besides the lessons learned in making the Italian-based Dekabrist-class and English-based Leninets-class boats, the Russians, who were very close to a quietly rearming Weimar Germany in the early 1930s, worked with the Dutch front company Ingenieurskantoor voor Scheepsbouw (IvS), which was, in fact, a dummy funded by the German Weimar-era Reichsmarine using design assets from German shipyards AG Vulcan, Krupp-Germaniawerft, and AG Weser to keep Berlin in the sub-making biz while skirting the ban on such activity by the Versailles treaty.

IvS had previously built boats and shared technology with Finland and Spain and it was with the latter’s planned Submarino E-1 that the Soviet S-series was based.

Spanish submarine E-1 at the shipyard in Cádiz. Built in Spain from 1929-30, Soviet engineers participated in her construction and trails. Although her design would go on to be used as the basis for both the German Type IA submarine and the Russian Stalinets class, ironically, the Spanish Navy never operated E-1, as she was sold to Turkey in 1935 just before the outbreak of the Spanish Civil War. She went on to fly the star and crescent until 1947 as TCG Gür.

Some 255 feet long and with an 840/1070 ton displacement, the basic Stalinets design was good for 19.5 knots on the surface and a cruising range of 4,000nm. Carrying four forward torpedo tubes and two sterns, they also mounted a 100mm deck gun and a 45mm backup as well as machine guns that could be set up for AAA use. Besides the six 533mm torpedoes in the tubes, they could carry another six spare fish.

Stalinets class

The first flight of three boats used German diesels, something that was corrected in follow-on ships that evolved slightly across their construction, hence the four different flights. In all, some 41 Stalinets would be completed. The first, C-1, was laid down on Christmas Day 1934 (because who needs religion in the worker’s paradise) and delivered on 23 September 1936 while a final eight whose construction began at around the same time languished on the builder’s ways during WWII, and were only finished post-war.

The subject of our tale is the most successful of the class. Of the 33 Stalinets class boats completed in time for WWII, 16 were lost. Of the 30 that saw combat patrols, 19 claimed tonnages. This would include the infamous S-13, which sank five ships including two large transports Wilhelm Gustloff and General Steuben, regarded as among the worst maritime disasters in history.

1946 Janes entry on what was left of the class at that time

Two submarines of the class were awarded the rank of Guards, and seven boats earned the Red Banner, only S-56 was awarded both distinctions.

Meet S-56

A 2nd series (IX-bis) Stalinets, S-56 was intended for service in the Pacific Fleet and therefore was assembled at the Dalzavod works at Vladivostok from a kit sent across Siberia from Leningrad starting on 24 November 1936. Launched Christmas 1939, she was commissioned on 20 October 1941, as the Germans were on the outskirts of Moscow.

With the Soviets eschewing combat against the Japanese until after Berlin was licked, on 6 October 1942, S-56, along with sisters S-51, S-54, and S-55, departed Vladivostok ahead of the ice to join the Red Navy’s Northern Fleet at Murmansk. They would be joined by the Leninists-class minelaying subs L-15 and L-16 sailing from Petropavlovsk on a 17,000-mile transoceanic voyage across both Pacific and Atlantic, maneuvering the seas of Japan, Okhotsk, Bering, Caribbean, Sargasso, Northern, Greenland, Norwegian and Barents with stops in Dutch Harbor, San Francisco, the Panama Canal, Guantanamo Bay, Halifax, and Rosyth.

At least that was the plan.

L-16 was lost en route with all hands, believed torpedoed and sunk by the Japanese submarine I-25 on 11 October 1942 approximately 500 miles west of Seattle. This was even though the Soviet Union and Japan were officially at peace. Fog of war, after all.

Via Combined Fleets on I-25:

While returning to Japan on the surface, I-25 spots two ships, apparently en route to San Francisco. The seas are rough. LCDR Tagami first identifies the ships as two battleships. Later, he identifies them as two “American” submarines. At 1100, he dives and fires his last remaining torpedo. It hits 30 seconds later. Several heavy explosions follow. One of the explosions wrecks a head aboard I-25.

The leading submarine starts to sink rapidly stern first with its bow up 45 degrees. A second explosion follows. When the smoke clears there is only an oil slick on the water. The submarine sinks with all 56 hands (a Russian crew of 55, a naturalized American and American interpreter/liaison officer Sergey A. V. Mikhailoff (USNR) who boarded the submarine at Dutch Harbor) at 45-41N, 138-56E. (Postwar, it is learned that the submarine was Soviet Cdr Dmitri F. Gussarov’s 1,039-ton minelayer L-16 en route from Petropavlovsk, Siberia via Dutch Harbor, Alaska to San Francisco.)

The accompanying Soviet L-15 reports seeing one more wake, fires five 45-mm rounds at I-25 and mistakenly claims a hit on I-25’s periscopes.

The five remaining Russian boats were captured several times by American and Canadian cameras while en route to Murmansk.

Unfortunately, the names of the American officers are not noted.

In March 1943, S-56 became part of the 2nd division of the submarine brigade of the Northern Fleet, after a voyage of 153 days.

Her combat career would encompass 125 days underway on eight patrols against the Germans in which she was declared overdue and likely destroyed no less than 19 times, more an issue of poor radio communications than anything else.

S-56 in the Northern Fleet

She logged 13 attacks and fired 30 torpedoes. This included several runs on German convoys, escaping a surface duel with a pair of escorts, surviving a glancing torpedo strike from the German U-711, and reportedly hitting at least one large freighter with a dud torpedo.

Although she would claim 14 enemy transports and warships sunk with a total displacement of 85,000 tons, her post-war validated tally is a good bit smaller (as are most subs from all sides).

Her successes detailed by U-boat.net, included:

  • 17 May 1943 sank the German tanker Eurostadt (1118 GRT) off the Kongsfjord.
  • 17 July 1943 sank the German minesweeper M 346 (551 tons) west of the Tanafjord.
  • 19 July 1943: Torpedoed and sank the German auxiliary patrol vessel NKi 09 / Alane (466 GRT, former British ASW trawler HMS Warwickshire) off the Tanafjord near Gamvik.
  • 31 July 1943 sank the German merchant Heinrich Schulte (5056 GRT) west of the Tanafjord.

Epilogue

In 1954, the now famed S-56 was sent back to her birthplace at Vladivostok via the then very perilous Northern Sea Route through the Arctic, thus becoming the first Russian submarine to circumnavigate the globe.

Decommissioned in 1955, she was retained in the Pacific Fleet as a floating charging station and damage control training hulk, renamed ZAS-8 and then UTS-14.

In 1975, on the 30th anniversary of VE Day, she was installed as a museum ship on the Korabelnaya Embankment, where she remains well preserved today, the last of her class.

She is also celebrated in several heroic Soviet maritime art pieces.


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.

Moving a battleship turret for the first time since 1992

The Iowa class battleships’ three dozen installed 16-inch 50 caliber Mk 7 guns, the largest, most destructive naval gun ever mounted on an American warship, have been quiet sentinels in pierside museum service for the past quarter century. Last fired in 1991, the big 16s have sat preserved since then.

Recently, the USS Iowa Musem made a bit of history when they turned one of the ship’s gun houses– Turret 3– to allow for some below-deck maintenance. It was the first time this was done on a BB-61-class battleship since 1992.

“Turning the turret was the result of months of hard work and research by our team, as well as input from Iowa class battleship veterans. We make it look easy, but it’s most definitely not,” notes the Museum.

The Museum staff had six cameras running on different decks within the turret when they rotated it on June 30, 2023. You’ll see four of those angles in the below video.

19 Rounds of Good to Go: The FN 545 Tactical .45 ACP

Announced just before this year’s SHOT Show alongside the new FN 510 in 10mm Auto, the FN 545 Tactical is essentially an upsized FN 509 Tactical chambered in .45 ACP. A round that will not die and today is seemingly even more popular than ever, the .45 ACP has been around for well over a century and the FN 545 Tactical stands ready to carry it deep, shipping complete with two magazines, including a flush 15+1 rounder and an extended 18+1 round mag.

The FN 545 Tactical scratches a lot of itches for a lot of folks. Those who love FN’s 509 series but wanted something in a .45 are in luck. Those who were interested in the hammer-fired FNX-45 Tactical but would prefer it in a striker-fired action are in luck. Those who want a suppressor/optic-ready .45 ACP with lots of extra capacity right out of the box are in luck.

Compared to guns like the Glock G21 Gen 5, it has better ergos, features, and capacity.

Plus, it is accurate and reliable in testing.

The full 500-round review is over in my column at Guns.com.

Great War British Sub and German Torpedo Boat found side by side…in parking lot

Kaiser Willy’s Schichau-Werke-built V1-class torpedo boat SMS S24 had a very active career that included firing her steel fish (unsuccessfully) at the British destroyers HMS Garland and HMS Unity at Jutland.

Schlacht vor dem Skagerrak, Deutsche Schlachtschiffe und Torpedoboote in Aktion (German battleships and torpedo boats in action during the Battle of Jutland, May 31, 1916) by Claus Bergen

Meanwhile, HM Submarine E-52, commissioned in 1917, surprised and sank the German U-boat UC-63 near the Goodwin Sands before the year was up, with her skipper earning the DSO.

Three RN E-class boats, including E-52, circa 1917.

By 1921, with a tepid peace on the Continent (at least in Britain), both ex-E52 and ex-S24 had been disposed of and sold to Brixham Marine & Engineering Company.

Towed to Brixham’s yard on the River Dart, rather than being broken up for their value in scrap, the vessels were apparently used to strengthen a bank in Coombe Mud, then over time buried to create what is now Coronation Park.

Now, RN has reported that a team from the University of Winchester, working on research from RN LT Tom Kemp, believes they have found the intact hulks under the surface of the park, as verified by ground penetrating radar.

“It’s been my personal hobbyhorse for the better part of the past year,” says Tom. “Confirming the final resting place of one of His Majesty’s Submarines – and a pretty successful one at that – would serve to remind and reiterate that our naval heritage is all around us and can often be clawed back from obscurity. Our time and energy could scarcely be better spent.”

The commercial camouflage industry in the 1942-45 era was on point!

In all, Consolidated would produce no less than 739 PB4Y-2 Privateers (navalised B-25s), 977 PB4Y-1s, and 217 PB2Y Coronados during the war, as well as 1,871 PBY Catalinas, providing the backbone of the WWII Allied patrol bomber force.

By 1945, the company employed 45,000 around the Bay Area– under cover.

Know an organization that needs an (as is/where is) tall ship ?

Built 1989-1991 by Don McQuiston & Sons in San Diego as the S/V Tuolumne, Amazing Grace is an 83-foot (sparred length) topsail schooner working day trips since 2015 for East Islands Excursions out of San Juan, P.R. She is seen here in the Tall Ships Parade in San Diego Bay for Festival of Sail in 2011. Her current condition is…well, keep reading

Reposted from Marlinspike Magazine (emphasis mine):

“East Island Excursions is looking to let go of the Amazing Grace, an 82 ft Baltimore Clipper Style vessel currently located in San Juan Bay, Puerto Rico.

“She has been fully operational as a charter vessel since 2015 with a 26-passenger plus 3 crew COI for inland waterways. The license is currently on hold for several USCG 835 deficiencies. The concerns are mainly in the mast and bow sprit areas.

“All standing and running rigs were replaced in 2018. The vessel was repowered in 2019. New sails, electrical package, forward scuttle, and butterfly hatches were completed in 2021.

EIE would like to consider donating to any 501C3 non-profit group that is interested in taking over the vessel. The latest rig survey and USCG documents will be available to any interested parties.”

“The vessel could reacquire COI with appropriate repairs or be utilized as a private vessel. East Island Excursions would prefer the vessel to be refurbished with a willing organization. Please don’t delay as hurricane season is upon us.

“Contact Captain Michael Patterson at 831-776-2182 / michael@captms.com or Sorren Varney at 787-860-3434 / sorren@eastislandpr.com for more information or to see the vessel in person.”

Happy Bastille Day

14 July 1910. Béni Ounif, Bechar, Algeria. Parade of Senegalese Tirailleurs on the occasion of the Bastille Day celebrations there:

Réf. : D0388-121-003-0639 Jules Imbert/ECPAD/Défense

As detailed previously, Senegal– a traditional French ally who provided the Republic the use of the famed Tirailleurs Sénégalais for twin World Wars (where 200,000 served in the first and 140,000 in the second) as well as Algeria and Vietnam Indochina– produced some of the most reliable of French colonial troops for generations.

These hardy Senegalese riflemen were stationed throughout France, Asia, and Africa, where their descendants often endure in their own unique enclaves.

Senegalese Tirailleurs from a March 1913, newspaper colour supplement

The first Senegalese Tirailleurs were recruited in 1857 while the last had their contracts expire in the French Army in 1965, six years after the independence of Senegal and the French Soudan. At their peak in 1917, they formed no less than 89 battalions.

As for Béni Ounif, today it is a desert border town on the Algeria–Morocco border and is probably best known for the brutal 1999 massacre by guerillas who stopped a bus at a fake roadblock, slashed 23 throats, then reportedly faded back into the Moroccan interior.

Odds are a company of Tirailleurs would have put a quick halt to that. Just saying.
