Navy gives LCS’s minesniffer a thumb’s up (finally)

The Navy last week announced the completion of developmental testing for Raytheon’s AN/AQS-20C mine-hunting sonar system at Naval Surface Warfare Center, Panama City Division.

This thing:

For these things:

PACIFIC OCEAN (Feb. 27, 2019) The Independence variant littoral combat ships USS Independence (LCS 2), left, USS Manchester (LCS 14), and USS Tulsa (LCS 16) are underway in formation in the eastern Pacific. Littoral combat ships are high-speed, agile, shallow draft, mission-focused surface combatants designed for operations in the littoral environment, yet fully capable of open ocean operations. As part of the surface fleet, LCS has the ability to counter and outpace evolving threats independently or within a network of surface combatants.

The presser:

The AQS-20C is the next generation of the AN/AQS-20 system designed to be incorporated into the Littoral Combat Ship Mine Countermeasures Mission Package. The system consists of four sonar arrays: two side-looking arrays; a gap-filler sonar array; and a forward-looking sonar array providing simultaneous detection, localization, and classification of bottom mines, close-tethered moored mines, and volume-moored mines.

The system delivers high-definition images of bottom mines, providing the operator with both range and contrast data that combine to form a three-dimensional image during post-mission analysis to aid in mine identification.

Developmental testing verifies that a system’s design meets all technical specifications and that all contract requirements have been met. During testing the Raytheon-developed towed sonar sensor conducted 12 underway missions in various operational modes and at different depths at four separate NSWC PCD test ranges. The missions were conducted aboard the test vessel M/V Patriot.

The AQS-20C will now be integrated with and deployed from the Mine Countermeasures Unmanned Surface Vehicle (MCM USV), a long-endurance, semi-autonomous, diesel-powered, all-aluminum surface craft that supports the employment of various mine countermeasure payloads. The MCM USV can be launched and recovered by the LCS, from other vessels of opportunity or from shore sites to provide minesweeping, mine-hunting, and mine neutralization capabilities. The MCM USV is currently undergoing developmental testing as a component of the Unmanned Influence Sweep System at the South Florida Test Facility in Fort Lauderdale, Florida.

Test results will now undergo scoring and performance assessment leading up to a final developmental testing report that is expected to be completed in the spring. Findings from this report will be used for future performance improvements of the system.

RN adding a pair of ‘Littoral Strike Ships’ which sound cooler than what they are

UK Defence Secretary Gavin Williamson this week announced a concept and development phase for two new vessels – called Littoral Strike Ship.

These are defined in a presser as:

Littoral Strike Ship are vessels which can command an assault force from anywhere in the world – carrying everything from helicopters and fast boats to underwater automated vehicles and huge numbers of troops. They are designed to be able to get in close to land – with ‘littoral’ literally meaning the part of the sea which is closest to the shore.

And could look like this converted container ship concept:

Why are they needed?

The RN’s “Gator” assets currently number just a pair of 21,000-ton Albion-class landing platform docks (LPDs)– HMS Albion and HMS Bulwark— as well trio of relatively new 16,160-ton Bay-class dock landing ships (LSD)– the latter used to be four but they sold one, Largs Bay, to Australia in 2011. The Bays are manned by civil mariners of the RFA, which is basically the British version of the MSC. Each of the five aforementioned British LPD/LSDs can comfortably carry about one half of a Commando battalion (of which the RMs have two, 40 Commando and 45 Commando) as well as a smattering of Chinooks, LCUs, and LCVPs.

Only one vessel on the RN’s list in recent years could carry a full Commando unit, HMS Ocean, and she was just sold to Brazil with a lot of life left in her.

So, on the outset, it looks like between the five current ‘phibs available to the RN, they could land the two 700-man Commandos available to them without much of an issue. With that, why the new vessels?

From the press conference:

Under plans being looked at by the Royal Navy and Royal Marines, these assault ships would be forward deployed permanently away from the UK.

Said Williamson, “Our vision is for these ships to form part of 2 Littoral Strike Groups complete with escorts, support vessels, and helicopters. One would be based East of Suez in the Indo-Pacific and one based West of Suez in the Mediterranean, Atlantic, and Baltic. And, if we ever need them to, our two Littoral Strike Ships, our two aircraft carriers, our two amphibious assault ships Albion and Bulwark, and our three Bay Class landing ships can come together in one amphibious task force. This will give us sovereign, lethal, amphibious force. This will be one of the largest and best such forces anywhere in the world.”

Ahhhh, so basically Littoral Strike Ship = Expeditionary Sea Base (ESB) platform but with a British jack.

USNS Lewis B. Puller (T-ESB 3) employs a flight deck for helicopter operations. T-ESB 3 is able to carry four MH-53E helicopters or five Twenty Foot Equivalent Unit Military Vans and still have room to maneuver and store other equipment.

Which makes sense.

Russia can crank out 10K rounds per day for their Thunderball-era underwater gatts

Long considered essential beachwear for Russian frogman-types, production is ramping up for the special 4.5mm and 5.66 mm dart-projectile ammo used in the country’s underwater-capable guns. The 4.5mm round fires a mild-steel flechette dart loaded atop a 39.5mm bottlenecked case and is used in the 4-shot SPP-1 pistol while the larger 5.66mm cartridge was designed for the APS rifle system.

The APS

Due to automation, the factory can now produce 10,000 of these specialty rounds per day.

Navy continues to experiment with expeditionary packages

A few years ago the Navy put together a Special Purpose Marine Air-Ground Task Force (SPMAGTF) built around just 250 Marines with a quartet of four CH-53E Super Stallion helicopters. Deployed to Central America in a series of joint exercises and nation-building projects under Southern Command, they spent six months underway.

In recent months, a few additional pages in the same book have been added.

Sailors and Marines assigned to Littoral Combat Group One (LCG-1) just returned to Hawaii after spending six months in the Eastern Pacific– an area that sees few USN deployments. Consisting of just two-three vessels– USS Somerset (LPD 25) and USS Wayne E. Meyer (DDG 108), along with the occasional support of the oiler USNS Yukon (T-AO 202) — they embarked the 300~ Marine SPMAGTF-Peru augmented by Coast Guard LEDETs, the latter to perform stops on narco subs prone to the region. They conducted ops and exercises with partners in Chile, Ecuador, and Peru.

Cuenca is a German-made Lürssen TNC 45 Seawolf-class fast attack craft. (U.S. Navy Photo by Littoral Combat Group 1 Public Affairs/Released)

Air assets on Somerset included at least two CH-53Es, assigned to the “Heavy Haulers” of Marine Heavy Helicopter Squadron (HMH) 462 and a couple UH-1Y Hueys assigned to the “Vipers” of Marine Light Attack Helicopter Squadron (HMLA) 169.

USS Somerset is part of Littoral Combat Group One, which is deployed in support of the Enduring Promise Initiative to reaffirm U.S. Southern Command’s longstanding commitment to the nations of the Western Hemisphere. (U.S. Navy Photo by Mass Communication Specialist 2nd Class Kyle Carlstrom)

Moving past the LSG and SPMAGTF’s, there was the single-vessel Task Force Koa Moana 2018.

Using a company-sized force of Marines embarked aboard USNS GySgt Fred W. Stockham (T-AK-3017), an MSC-manned Shughart-class container & roll-on roll-off support vessel, the 55,000-ton prepositioned supply ship sailed around the Pacific, stopping at a string of islands from Tahiti to Palau, Tinian and Guam, performing joint operations with local governments and French military assets (Tahiti is still a Paris-controlled colony, after all.)

Some 130-ish TFKM Marines and Sailors called the civilian-manned Stockman home for two months last year, in humanitarian assistance missions across Oceania.

As described by the USNI, “TF Koa Moana included 130 members from the West Coast-based I Marine Expeditionary Force, officials said, plus fly-in detachments of Marines and Navy personnel from Okinawa, Japan, and Guam.”

Sure, they aren’t units capable of forcing a beach against a top-tier enemy, but, besides disaster response, LE support, training, and humanitarian missions, groups such as these–if needed– could probably pull off TRAP recoveries, non-combatant evacuations, and FAST-team style legation reinforcements, which in the end, can help take up the slack from overworked Amphibious Ready Groups and Carrier Task Forces.

Just keep them out of harm’s way in contested areas as this could be a way to get a handful of guys in a lot of trouble, fast.

Warship Wednesday, Jan. 2, 2019: Splinter No. 330 (of 448)

Here at LSOZI, we are going to take off every Wednesday for a look at the old steam/diesel navies of the 1833-1946 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, Jan. 2, 2019: Splinter No. 330 of 448

Here we see the mighty 110-foot Submarine Chaser No. 330 of the U.S. Navy en route across the Atlantic, circa September-October 1918, to take the fight to the Kaiser’s unterseeboot threat. The hearty little class, more akin to yachts or trawlers than warships, were hard to kill and gave unsung service by the hundreds, with SC-330 one of the longer-lasting of the species.

In an effort to flood the Atlantic with sub-busting craft and assure the U-boat scourge was driven from the sea, the 110-foot subchasers were designed by Herreshoff Boat Yard Vice President, the esteemed naval architect Albert Loring Swasey (Commodore of the MIT Yacht Club in 1897) on request of Asst Naval Secretary Franklin D. Roosevelt in 1916 and rushed into construction the next year. It was believed the vessels could be rushed out via commercial boat yards at $500K a pop.

Derided as a “splinter fleet” the SCs were built from wood (the most excellent Subchaser Archives says “Frame/floors: white oak. Planking: yellow pine. Deck planking: Oregon pine”), which, when powered by a trio of Standard 220-hp 6-cylinder gasoline (!) engines, a 24~ man crew could get the narrow-beamed vessel underway at a (designed) top speed of 18 knots, which was fast enough for U-boat work at the time.

Armed with a 3″/23cal low-angle pop gun forward– which was still capable of punching a hole in a submarine’s sail or pressure hull out to 8,000 yards– a couple of M1895 Colt/Marlin or Lewis light machine guns for peppering periscopes, and assorted depth charges (both racks and projectors), they were dangerous enough for government work.

To find their quarry, they were equipped with hydrophones produced by the Submarine Signal Company of Boston (which today is Raytheon), of the C-tube and K-tube variety.

As noted by no less authority than Admiral William S. Sims in a 1920 article reprinted in All Hands in 1954:

“The C-tube consisted of a lead pipe-practically the same as a water pipe which was dropped over the side of the ship fifteen or
twenty feet into the sea; this pipe contained the wires which, at one end, were attached to the devices under the water, and which, at the other end, reached the listener’s ears.”

When a cavitation submarine was near it “showed signs of lively agitation. It trembled violently and made a constantly increasing hullabaloo in the ears of the listener.”

Besides escorting coastal convoys (subchasers had short legs) and watching for surfaced boats, 3-packs of the hardy little vessels would drift and listen, their K-tubes and C-tubes in the water, depth charges at the ready.

From Sims:

The three little vessels, therefore, drifted abreast-at a distance of a mile or two apart-their propellers hardly moving, and the decks as silent as the grave; they formed a new kind of fishing expedition, the officers and crews constantly held taut by the expectation of a “bite.” The middle chaser of the three was the flagship and her most interesting feature was the so-called plotting room. Here one officer received constant telephone reports from all three boats, giving the nature of the sounds, and, more important still, their directions. He transferred these records to a chart as soon as they came in, rapidly made calculations, and in a few seconds, he was able to give the location of the submarine. This process was known as “obtaining a fix.”

This photograph captioned “Battle Formation of Sub-chasers”, seems to depict the vessels in a columnar formation, which would be unusual for engaging with a submarine. The battle formation was most commonly ships arranged in a line abreast. From the T. Woofenden Collection at subchaser.org. https://www.subchaser.org/battle-formation via NHHC

The first of the class, SC-1, was built at Naval Station New Orleans and commissioned in October 1917. Others were built at Mare Island, New York (Brooklyn), Charleston, Norfolk, and Puget Sound Naval Yards; by Matthews Boat in Ohio, Hodgdon Yacht in Maine, Hiltebrant in Kingston, College Point Boat Works, Mathis Yacht in New Jersey, Barrett SB in Alabama, Great Lake Boat Building Corp in Milwaukee…well, you get the idea…they were built everywhere, some 448 vessels over three years.

Our subject, SC-330, was handcrafted with love by the Burger Boat Co., Manitowoc, Wisconsin— the only such craft built by the yard– and commissioned on 8 February 1918. Of note, Burger is still in the yacht biz today.

She cut her teeth with the early submarine hunter-killer group centered around the Paulding-class four-piper destroyer USS Jouett (DD-41) on the East Coast.

Assigned to Division 12 of Submarine Chaser Squadron 4 for service overseas during the Great War, SC-330 headed overseas in September 1918, ending up in the Azores.

Rushed into service, at least 121 of the 110s made it “Over There” before Versailles, including no less than 36 that operated in the Med from the island of Corfu. Not bad for ships that only hit the drawing board in late 1916.

The boat carried two officers, a CPO, five engine rates, three electricians (radiomen), a BM, a QM, 3 hydrophone listeners, a couple of guys in the galley, and 5-7 seamen. Crews were often a mix of trawlermen serving as rates, Ivy League yachtsmen as officers, and raw recruits making up the balance. In many cases, the Chief was the only regular Navy man aboard. Life was primitive, with no racks, one head, and hammocks strung all-round.

Most crews went from civilian life to getting underway in just a few months. The fact that these craft deploying to Europe did so on their power– effectively in a war zone as soon as they left brown water on the East Coast– with very little in the way of a shakedown is remarkable.

The ships did what they could and, when used in a littoral, performed admirably. For example, a squadron of 11 of these chasers screened the British-French-Italian naval forces during the Second Battle of Durazzo in Oct. 1918, destroying mines that threatened the bombarding ships and driving off an Austrian submarine trying to attack the Allied fleet.

However, when in the open ocean, things could get real for them.

As noted by an Irish site referencing the 30 110s under Capt. A.J. Hepburn who arrived in August 1918:

The 110 foot subchaser was a fine sea boat, but was never designed to withstand the wild Atlantic seas off Ireland. Constant leaks from decks and windows, choking petrol fumes in the officers quarters, and constant seasickness from the rolling motion, were the lot of crews of these craft.

In heavy weather they would be almost awash, with only the pilot house showing above the waves. The depth charge racks were felt to be too heavy and made the vessels prone to taking seas over the stern. Many reports of German submarines from coastwatchers and others were actually subchasers ploughing through heavy seas.

Once the war ended, SC-330 was sent back to the States, served in Gitmo for a time, and was laid up on the Gulf Coast in 1919.

SC-330 caught a reprieve. In the summer of 1920, she was sent up the Mississippi River system and served on semi-active duty through the 1920s and 30s, training Naval Reservists in the Midwest. As such, the little boat and those like her cradled the USNR through the interwar period, and, without such vessels, WWII would have looked a lot different.

Of her 448 sisters, more than 100 were transferred to the French during the war, some to the Coast Guard in the 1920s, and most liquidated by the early 1930s as they grew long in the tooth. Wood vessels with gasoline engines weren’t highly desired by the Navy at the time, after all.

USCGC Vaughan, ex-USS SC-152, was built by the Gibbs Gas Engine Co., Jacksonville, FL but served her career in Coastie White off Key West and San Diego during Prohibition. With Volstead on its way out, she was decommissioned on 28 March 1928 and sold. Her end is similar to most SCs., discarded before they had 10 years on their rapidly deteriorating wooden hulls.

Few of the 110s survived the Depression on Uncle’s inventory and SC-330 was the only one of her 100-ship block (from SC 301-400) to serve in WWII, likely continuing her role as a training ship. As most of her life had been spent in freshwater– usually wintering ashore to keep out of the ice– this likely contributed to her longevity.

Only about a dozen or so 110s were carried on the Naval List during the Second World War. (The other 12 were: SC-64, SC-102, SC-103, SC-185, SC-412, SC-431, SC-432, SC-437, SC-440, SC-449, SC-450, SC-453, one of which was lost and three were retired before the end of the war. In addition, SC-229 and SC-231 were in USCG service as the cutters Boone and Blaze, respectively). Most were in YP or training duties, although some did mount ASW gear to include mousetrap bomb throwers and depth charges, just in case.

SC-33 was one of the last four of her type in service, decommissioning and struck from the Navy Register on 22 June 1945, then transferred to the War Shipping Administration on 8 October 1946. (The only longer-lasting 110s were: SC-431 transferred to WSA on 12/9/46, SC-437 on 3/21/47, and SC-102 on 1/3/47).

While these craft are all largely gone for good, extensive plans remain of the vessels in the National Archives.

Inside the Helge Ingstad

Many naval shipwrecks are in deep water or in mud so nasty that even if in shallower depths, have visibility of about nil. Not so with the recently lost Helge Ingstad, which for now at least, is in the shallows of a crystal clear fjord in Norway at depths that enable small surface ROVs and scuba-equipped salvage work.

For those under a rock for the past month, HNoMS Helge Ingstad is a Fridtjof Nansen-class frigate of the Royal Norwegian Navy. On 8 November 2018, the frigate collided with the tanker Sola TS in Norwegian waters, was severely damaged in the collision and beached:

The cables didn’t hold and she slipped down the ledge where she rests today.

The Norwegian Navy this week released two videos from the wreck. One of them piloting the Blueye Pioneer underwater drone inside her hull, and another recovering Naval Strike Missile (NSM) launch canisters from her topside.

The NSM is a 13-foot-long, 900-pound anti-ship missile produced by Norway’s Kongsberg Defence & Aerospace and it is being shopped by Raytheon in the U.S. to replace Harpoon on frigates and LCS vessels. The range is 100+ nm and it is optimized for use in so-called green or blue water. Nansen-class frigates tote eight of these. More on the NSM here.

Of note, Blueye is also a Norwegian company. More on the ROV, which only runs like $6K, here.

Good deal on slightly used minesweepers, some assembly required

If you are in the market for some pre-owned warships, the Royal Australian Navy wants to make a deal. Working through a commercial service, the Navy advertised the HMAS Hawkesbury and HMAS Norman for sale “Sold As Is Where Is.”

The 172-foot long mine hunters have composite hulls designed to “flex inwards if an undersea explosion occurs nearby,” which is always a good thing.

HMAS Hawkesbury left, and HMAS Norman are Huon-class coastal mine hunters commissioned in 2000. They have been in reserve for the past seven years. (Photo: Royal Australian Navy)

Built in 2000 as part of a six-ship class to an Italian design (Lerici-class, the same as the U.S. Navy’s short-lived Osprey-class MHCs) both Hawkesbury and Norman were laid up in 2011 and have been in storage ever since while the other four ships have remained with the fleet.

Sadly, it looks like their DS30B 30mm Bushmaster cannons and M2 .50-cal machine guns have been removed, but the vendor offering them for sale suggests they could be turned into luxury yachts or charter vessels.

Not mentioned is a Jacques Cousteau/Steve Zissou-style recycle.

No price is listed but the vendor, Grays Online, does caution that the ships have had their shafts and propellers removed and would have to be towed off by the buyer, saying, “inspection is highly recommended.”

Nasty making it back

With the hundreds of wooden PT boats all liquidated shortly after WWII ended, the Navy in the 1960s found themselves in need of a handful of small, fast, and heavily armed craft for “unorthodox operations” in Southeast Asia.

These wooden-hulled Norwegian-designed 80-foot boats, powered by a pair of Napier Deltic turbocharged diesel engines, could make 38-knots but, with a 40mm Bofors single, an M2 .50 cal/81mm combo, and 20mm cannons, they could deal some hurt.

Here we see the Dubuque-class gunboat USS Paducah (Gunboat No. 18) of the U.S. Navy on a sunny Spring day, 28 May 1912, while assigned to the Caribbean Squadron. This humble 200-feet of rock and roll served Uncle in both World Wars and kept on chugging post-1945.

Designed at the turn of the century as a slow (12 knot) but decently-armed (2 4-inch, 4 6-pounders, 2 1-pounders) steel-hulled gunboat capable of floating in two fathoms of brackish water, the Dubuque-class gunboats were both built at the Gas Engine and Power Co. and Charles L. Seabury Co., Morris Heights, N.Y.

Both class leader Dubuque and sister Paducah were the first U.S. Navy warships named after those mid-sized river cities, which seems appropriate as the ships themselves could be used in rivers, bays, and lakes otherwise off-limits to larger men-of-war of the day. Still, they were handsome ships with a pair of tall stacks, twin masts, and a raked bow, and fast enough for what they were intended for.

With their armament pumped up while under construction from a pair of 4″/40cals as designed to a full set of six of these guns (rivalling light cruisers of the day) and augmented by a Colt M1895 Potato-Digger machine gun for landing duties, they were well-suited to wave the flag in far-off climes on the cheap and patrol out-of-the-way backwater ports in Latin America, West Africa, the Pacific and the Caribbean.

Yes, they were the Littoral Combat Ships of 1905!

Commissioned 2 September 1905, Paducah was soon dispatched to the Caribbean Squadron “to protect American lives and interests through patrols and port calls to the Caribbean and Central and South American cities.”

Patrolling Mexican waters in the aftermath of the Vera Cruz incident through the summer of 1914, she then returned to her Caribbean operations, performing surveys from time to time.

When the U.S. entered WWI in 1917, Paducah was tapped to perform overseas escort and coastal patrol duties in Europe, reaching Gibraltar 27 October. Based from there, the plucky gunboat escorted convoys to North Africa, Italy, the Azores, and Madeira.

She logged an attack on an unidentified U-boat 9 September 1918 after it had sunk one of her convoys, and was credited with possibly damaging the submarine, although this was not confirmed by post-war audits. Her sister Dubuque spent the Great War investigating isolated harbors and inlets in the Caribbean and on the coasts of Venezuela and Colombia to prevent their use by German submarines, an ideal tasking for such a vessel.

After post-WWI survey duty in the Caribbean, Paducah was re-engined with twin 623.5ihp vertical triple-expansion engines, and her armament reduced. She then transferred to Duluth, Minn in May 1922, to serve as a training ship for Naval Reserve forces in the 9th District. Sister Dubuque likewise pulled the same service, taking Reservists on cruises from her home port of Detroit into Lakes Superior and Michigan every summer, and icing in for the winter. Good duty if you can get it.

When WWII came, both Paducah and her sister returned to the East Coast in early 1941, and, based at Little Creek, Va. throughout the conflict, trained Armed Guard gunners in Chesapeake Bay for details on merchant vessels. Some 144,970 Armed Guards served during the war, trained at three bases, with over 1,800 killed or missing in the conflict. Witnessing a staggering 1,966 air attacks and 1,024 submarine attacks, 467 guard crews participated in destroying enemy planes in addition to engaging surface raiders and submarines.

Decommissioning 7 September 1945, both transferred to the Maritime Commission 19 December 1946 and Paducah was sold the same day to one Maria Angelo, Miami, Fla. Then came a second career for Paducah as Dubuque was sent to the breakers.

Purchased for a song by the Israeli group Haganah and renamed Geulah (Hebrew: Redemption) a scratch crew of mostly-American volunteers sailed her first to France and then Bulgaria, taking aboard an amazing 2,644 Ma’apilim refugees for passage to Palestine through the British blockade.

The British trailed her off Palestine and raided the vessel in Haifa harbor, impounding the ship among others used by the Israelis until the new government formed. (See fellow Warship Wednesday alumni Gresham).

Later the Israeli Navy was able to reclaim Paducah/Geulah in 1948 after independence, but following inspection, the desperate organization realized they were not that desperate, and, after a brief stint as a tramp steamer, sold her for scrap in Naples in 1951.

The only other Paducah commissioned in the Navy was the 109-foot large harbor tug, YTB-758. Built at the Southern Shipbuilding Corp., Slidell, La., she joined the fleet in 1961 and was decommissioned 1970. Struck from the Naval Register, 25 June 1999, she is in commercial service today in Connecticut as Patricia Ann, berthed at New London.

The silver punch bowl from the old gunboat Paducah, donated to the Quilt City in 1946 by the Navy, is on display at the city’s Market House Museum.
