Commander Lionel James Spencer Ede DSO RN, Commander of Minesweeping and Patrol, Dover, testing a rarely seen stripped Lewis Machine Gun probably on board HMS ML 297  1941. These guns usually have their water jackets wrapped around the barrel and forend. The dated armament was common on the launches.

ML297 was a Fairmile B-class motor launch, the 112-foot workhorse of the RN of which a staggering 650 were completed during the War.

Originally tasked as anti-invasion gunboats in the dark days of 1940, they were to slaughter German landing craft near shore with WWI surplus QF 3-pounder Hotchkiss (47mm / L40) cannon and similarly vintage machine guns.

Once Hitler called off Operation Sea Lion, the Brits found use for the launches as subchasers crammed full of depth charges, minesweepers with a few basic trawls, and then finally as rescue motor launches, beach control and ambulances during the subsequent Allied amphibious landings in Europe.

As for the good Lt. Cdr. Spencer, he retired from the RN 10 Oct 1953 at the end of 28 years service after holding several wartime commands including HMS Salamander, Blyth and Rhyl.

Meet ACTUV

DARPA just released some neat but brief 360-view footage of their Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) including some of it underway at a good clip (27 knots). The 132-foot USV is meant to be the expendable subchaser of the 21st century, and actually looks pretty sweet.

If they can get past concept and put 50-100 of these cheaply in the Western Pac, networked all sweet to a central ASW War Room, it could really negate all the skrilla the Norks and PLAN are dropping on subs.

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 of their own, which sometimes takes them to the strangest places. – Christopher Eger

Here we see the Royal Navy Devonshire-class armored cruiser HMS Hampshire during her brief life. Although a warship in the RN during the toughest period of the Great War at sea, Hampshire is remembered more for whom she carried rather than where she fought.

The Devonshires were a six-pack of mixed armament (4×7.5-inch; 6×6-inch) cruisers that were popular around the 1900s. These 11,000-ton ships were designed to act independent of the main battle fleet and could cruise worldwide and protect sea-lanes from enemy surface raiders, or in turn become a surface raider themselves.

The concept was invalidated in the Russo-Japanese War when Russian armored cruisers failed to make much impact on the extensive Japanese maru fleet, while they were sent to the bottom wholesale in warship v. warship ops. In turn, the armored cruiser concept was replaced by the more traditional all-big-gun fast heavy cruiser, and their flawed cousin the battlecruiser, both of which reigned for some time through WWII.

Still, the Devonshires, though obsolete almost as soon as they were commissioned, gave yeoman service while they were around.

The subject of our tale, Hampshire, was laid down at Sir W G Armstrong Whitworth & Co Ltd in Elswick, Newcastle upon Tyne, England, 1 September 1902. She was the fourth such warship to carry that name on the fleet list, dating back to a 46-gun ship built in 1653 for Cromwell’s Commonwealth.

Ironically, Hampshire was completed 15 July 1905, just six weeks after the Battle of Tsushima that largely invalidated her existence. Her cost, £833,817.

After cutting her teeth with the 1st Cruiser Squadron of the Channel Fleet for a few years as a shiny new warship for HM, Hampshire had her hull scraped and boilers reworked before being transferred to Hong Kong to sit the China Station in 1912.

When the balloon went up, Hampshire sortied for the German colony of Yap to destroy the wireless station there, on the way sinking the German collier SS Elspeth just seven days after the England joined the war. The lack of coal for Spee’s ships would be an albatross that ultimately ended his squadron. (Note: Hampshire’s sister, HMS Carnarvon, was present at the Battle of the Falklands and got licks in on both Spee’s SMS Gneisenau and Scharnhorst).

While in the Pacific, Hampshire just barely missed an opportunity to sink the much smaller cruiser SMS Emden (4200-tons; 10x105mm guns), however, she did carry that stricken raider’s skipper, Kvtkpn. Karl von Müller, to POW camp in England, while escorting an ANZAC troop convoy through the Indian Ocean and the Red Sea to Egypt.

At Malta

Arriving back in home waters in January 1915, Hampshire landed Müller, who was sent on to captivity at the University of Nottingham, then joined the Grand Fleet.

Fighting at Jutland with the 2nd Cruiser Squadron, her 7.5-inchers tried but failed to hit any German ships during that epic surface battle. Likewise, Hampshire herself came away unscathed.

In July, she was chosen to carry Field Marshal Horatio Herbert Kitchener, 1st Earl Kitchener KG, KP, GCB, OM, GCSI, GCMG, GCIE, PC, “Baron Kitchener of Khartoum” to Imperial Russia via the White Sea. Kitchener and his staff were to help revitalize the Tsar’s war machine; after all, he was literally the face of the mighty BEF, which had swollen from a small volunteer force of just six infantry divisions to a modern army capable of holding the Kaiser in place on the Western Front.

Leaving Scapa Flow for Archangelsk, Hampshire and her two destroyer escorts ran afoul of a minefield laid by U-75 in May.

There, on 5 June off the mainland of Orkney between Brough of Birsay and Marwick Head, Hampshire struck a single mine and was holed, sinking rapidly in just 15 minutes by the bow, taking 737 members of her crew and passengers to the bottom with her. Only 12 crewmen survived and made it to shore.

One other purported survivor, Boer spy Frederick “Fritz” Joubert Duquesne, known to history as “The man who killed Kitchener” claimed to have guided a German U-boat to sink the HMS Hampshire via torpedo from shore, though nothing supports that claim.

Attaching himself to Kitchener’s staff, he claimed to have escaped Hampshire alone to be picked up by a waiting U-boat. But anyway…

The news of Kitchener’s loss, coming after the carnage of the Somme, was a blow to the Allied war effort.

Further, without a shot in the arm, the Tsar’s army largely walked away from the war the next year, though not even the hero of Khartoum would likely have changed that.

Remnants of Hampshire are considered relics in the IWM collection.

As for her sisters, the five other Devonshires were luckier, with the exception of HMS Argyll, which wrecked on the Bell Rock, 28 October 1915. The four surviving ships were paid off soon after the war and sold for scrap.

Hampshire‘s name, though currently not in use, was bestowed to a County-class guided missile destroyer (D06) in 1963 and scrapped in 1979 after just 16 years service as part of the Labour Government’s severe defense cuts pre-Thatcher.

A memorial, planned by the Orkney Heritage Society is trying to raise £200,000 to more extensively commemorate the ship.

Some 737 names will be inscribed in panels on the wall, which will arc around the tower, with a separate panel for the staff of Lord Kitchener – and another one bearing the names of nine men killed on the drifter Laurel Crown, which was blown up in June 1916 while trying to clear the minefield.

Hard luck minesweeper

In the 1950s, with mines being a big deal in opening stages of the Korean War, the possibility of the next naval war coming complete with thousands of Soviet M08 seamines, plus with a lingering half million unrecovered WWII era (and some even earlier WWI era) mines still unaccounted for in the waters that HMs ships sailed, the UK embarked on a new construction program of aluminium-framed, wooden planked hulled with non-magnetic fittings (easy to degauss) ocean-going sweepers– the Ton-class.

HMAS Curlew (M 1121), former HMS Chediston, served 1954-1991 and then for at least another 15 years as a fishing vessel, probably without the 40mm guns in the latter role...but you get the general idea.

In all some 119 of these handy and versatile little 152-foot long ships were commissioned, serving not only in the RN but over 30 units went on to the navies of Argentina, Australia, India, Ireland, Malaysia, NZ, and South Africa. They did yeoman work both as MCM craft and as generic patrol boats and auxiliaries.

One, HMS Packington, gained immortality as “R/V Belafonte” in The Life Aquatic with Steve Zissou, which is appropriate as Cousteau ‘s Calypso was a 136-foot YMS-1 sweeper herself.

LIFE_AQUATIC_D1-621

While Packington is still around as a luxury yacht in the Persian Gulf, the rest of the Tons have largely been Deep Six’d or sent to the breakers.

Except for HMS Bronington (M1115), whom seems to be cracking a bit of a sad lately.

HMS Bronington, Last of the Royal Navy’s Ton-Class, Sinks Next to Dock in England

From GCaptain:

A historic minesweeper formerly belonging to the Royal Navy has sunk while moored at Vittoria Dock in Birkenhead, England where it has been laid up for years.

The Bronington, one of the last vessels in the Royal Navy’s Ton-class, was discovered to have sank sometime between Thursday and Friday.

A witness told gCaptain on Friday that he last saw the vessel afloat Tuesday, but by Friday the ship had partially sank next to the dock in an upright position and was starting to roll onto its side.

The HMS Bronington was launched for the Royal Navy by Cook, Welton, and Gemmel shipbuilders in Yorkshire, England in 1953 and remained in active service until 1988. In 1989 the vessel was purchased by the Bronington Trust, a charity dedicated to her preservation and display to the public. The minesweeper was brought to Salford Quays and later opened to the public in 1992, but ownership eventually transferred to Mersey Docks and Harbour Company and the ship has been been laid up at Vittoria Docks since 2011.

The Quai Vat of the Plain of Reeds

In 1959 this chap by the name of Christopher Cockerell working for Saunders-Roe on the Isle of Wight came up with the first working and practical hovercraft, the “Saunders-Roe Nautical 1” (SR.N1), using an Alvis Leonides radial piston engine that drove a lift fan, and used ducted air from the fan for propulsion, producing a neat three-person craft that was capable of crossing the Channel at 35 knots.

This led to the 65-foot SR.N2 in 1961, which could make 73 knots (that’s seventy-three) and carry 48 passengers.

1963 brought the SR.N3 which was designed for military use and mounted a quartet of Bristol-Siddeley Gnome gas turbines, which enabled it to make 70 knots. The prototype didn’t work out too well but set the stage for what was to come.

Saunders-Roe and Vickers Supermarine merged to become the British Hovercraft Corporation (BHC) in 1966, and their fourth hovercraft, SR.N4, was a mammoth design that eventually topped out at 185-feet long. While the RN theorized using these as mine countermeasures craft, these vessels, of which six were eventually built, were used as passenger ferries as last as 2000.

Then came the primary subject of our tale, the SR.N5 military model of which 14 were built, half by BHC in the UK and the other half Bell in the U.S..

These 39-foot hovercraft were beamy, at 22 feet wide, and tall at almost 17 feet with the skirt inflated. Powered by a single 900hp Rolls-Royce Gnome turbine for both lift and propulsion, they could make 70 knots and carried enough jet fuel for about 3-4 hours of patrol. They could carry 16 troops.

The hovercraft were flown more than they were sailed

The hovercraft were flown more than they were sailed

Of the 7 British built vessels, one each were bought by the Sultanate of Brunei and the Canadian Coast Guard, the Brits kept four for the RNAS and the last UK boat went into commercial use. Of the 7 Bell hovercraft (designated SK-5s by that company and equipped with a GE engine), three were bought by the U.S. Navy as Patrol Air Cushion Vehicle (PACV, “Pac Vees”) and three by the U.S Army as Air-Cushion Vehicles (ACV) while the last U.S. boat was bought by San Francisco and Oakland Helicopter Airlines to use as a high speed ferry around the Bay Area.

Navy PACV, dig the mouth

In U.S. military service in Vietnam, these hovercraft picked up .50 cal and 7.62mm machine guns, a modicum of armor and sandbags to protect their four-man crews (thought they could get by with just two crewmen), and by 1966 were hot and heavy in South East Asia as part of Task Force 116 for the Navy craft while the Army’s boats followed the next year as the catchy Air Cushion Vehicle Test Unit, (Armor Platoon Air Cushioned) 39th Cavalry Platoon of 24 men.

Operating on the Mekong Delta, Cat Lo, and other hot spots, these half-dozen craft were soon dubbed Quai Vat (Monsters) by Mr. Charles as they raced around the swamps dropping off ARVN troops, Nung mercenaries and U.S. forces in hard-to-reach mudbogs. They were loud as hell (ever been around an LCAC?) but they were effective and, with the turbine shut down and the skirt on a relatively dry spot in the middle of the marsh, they were instant fighting positions.

By early 1968, the Army was even looking at (neat report here) making entire platoons of these craft, armed with 106mm recoilless rifles, Tow or Shillelagh missiles and FFAR rockets much like the helicopter gunships of the day.

Then came the epic six-day battle in the Plain of Reeds.

While conducting a combat operation in July 1968 in support of a South Vietnamese CIDG (Civilian Irregular Defense Force) unit and US infantry advisors, the Army SK5s were engaged in a 7-hour continuous fight with enemy forces.

During the reconnaissance sweep, the SK5 boats inspected over 60 houses along the waterline and discovered over 25 bunkers within the area.

After destroying the bunkers with their supporting infantry, the two hovercraft came under enemy fire. Both craft returned fire, but were unable to press the attack since the CIDG forces were unwilling to dismount into a potential ambush.

After disengaging, both ACVs repositioned to another area and were once again taken under fire. Both vessels returned fire and when the infantry inspected the area they discovered several killed enemy soldiers.

All was good until one of the Army craft, ACV #901, was destroyed on 9 Jan 1970. ACV #902 was destroyed in August 1970. The final Army unit, #903 was returned stateside.

The three Navy PACVs were likewise brought back CONUS and transferred to the Coast Guard in 1971.

Behold, the Coast Guard's hovercraft fleet!

Numbered CG-38101, 38102 and 38103, one (103) was lost in an accident while the first two were transferred to the US Army Mobility Equipment Research and Development Center on 25 April 1975, making the Army the only U.S. military hovercraft owner until the Navy took possession of the first 87-foot long Landing Craft Air Cushion (LCAC) vessels in 1986.

Of the British hovercraft, the original SR.N1 is held by the Science Museum at Wroughton, the only SR.N2 was broken up in the 1970s, SR.N3 was used for target practice, 4 of the 6 SR.N4 ferries were broken up and the two left are currently at the Hovercraft Museum in Lee-on-the-Solent but are facing imminent destruction.

Of the SR.N5s, one U.S Army boat, ACV 903, was returned to the states and is on display at the Transportation Museum in Ft. Eustis, VA. The sole remaining Navy PACV is at the Bellingham International Maritime Museum in Washington.

As for the British Hovercraft Corporation, moving past the SR.N5s they built the 58-foot SR.N6 in large numbers in the 1960s, being their most successful model of all with at least 54 completed. Popular in commercial use as a 58-passenger ferry, a military version capable of carrying a platoon was used by the Canadian Coast Guard, Italian Navy, Egyptian Navy, Iraqi Navy, Iranian Navy and the Saudi Arabian Frontier Force. The Shah liked them so much he ordered a half dozen larger 78-foot BH.7 hovercraft in the early 1970s while the CCG bought three of BHC’s last hovercraft, the 90 passenger AP1-88 boats before the company folded in 1984.

But we do have 91 U.S.-built LCACs today…

We all live in a yellow submarine…

Boeing’s massive 51-foot Echo Voyager, debuted yesterday, is an outgrowth of their 18-foot Echo Ranger and 32-foot Echo Seeker prototype testbed UUV’s– which were capable of 2-3 day operations– only Voyager would be capable of missions lasting months in theory.

Equipped with a hybrid rechargeable power system and modular payload bay, the midget sub sans crew, according to the video below, can do everything in theory from being a weapons platform, to launching and operating UAVs, to protecting infrastructure (read= smoking frogmen operating near sensitive bases), to submarine decoy, mine countermeasures, ASW search and barrier ops, and battlespace prep– though the video spends a lot of time talking about how it can help with oceanography and oil spills as well.

51-foot Echo Voyager 2
“Echo Voyager is a new approach to how UUVs will operate and be used in the future,” said Darryl Davis, president, Boeing Phantom Works. “Our investments in innovative technologies such as autonomous systems are helping our customers affordably meet mission requirements now and in the years to come.”

Long a staple of ASW training, exercise/recoverable torpedoes (extorps/rextorps) have been around for the Mk44, Mk46, Mk48, Mk50 and 54 variants and are typically the reworked warshot fish in which the explosive is replaced with an electronic signaling and guidance package that records the position of the device for data analysis after the exercise, and various signaling devices that help locate the torpedo in the water for recovery afterward.

They are pretty brightly marked, and colorful.

Caching done right

The Latvian-based Legenda relic hunter group found five sealed artillery powder cans while poking around the forests. When unearthed the munitions found inside led the group to conclude it was a WWII-era cache for saboteurs left behind by the Germans for individuals unknown.

The cache was explosives-heavy with some interesting items including magnetic limpet mines (at bottom) coal torpedos (center) and plenty of good old demo charges

Sure, all the stuff could just be planted for the photo op, but that seems pretty elaborate so we’d like to wish that the magic of it being buried for the better part of a century is the real deal.

The Latvians had no love lost for towards the Soviets (still don’t) and many signed up for the Waffen SS in mass and as auxiliaries to the German military and field police. A lot of that hearkened back to the fact that the remnants of Kaiser Willy’s forces helped keep the Reds out back in 1918-19, earning the country independence and once Uncle Joe rushed back in 1940 with a heavy hand, things kinda soured from there.

So whether the cache was meant for “stay behind” forces when the Germans left in 1945, or was assembled by the Soviets as a deniable supply for partisans of their own, is up to interpretation.

Ahh, German made abrasive. Pour this in the crankcase of your local T-34 sitting at the depot..

As the contents are absent on German weapons (though contains some commercial German made blaster’s tools), they contain French munitions dated to 1934 (which the Soviets wouldn’t have had access to but the Nazis captured in bulk in 1940) as well as Polish and Soviet made grenades made pre-1939 that also fell into German hands in quantity during the Blitzkrieg years– all kinda verifying the logic behind the relic hunters.

Of course, they could also be a CIA supplied cache for resistance groups fighting the Soviets in the forests in the 1950s made to be deniable as a German-WWII era set, as there is not a single U.S.-made or post-1945 item in the lot…just saying…

Navy to get more Archerfish

Big Blue is looking to get up to 1,000 additional Archerfish mine destructor vehicles (tiny, really maneuverable, slow torpedoes) for the AN/ASQ-235 Airborne Mine Neutralisation System (AMNS).

Developed by BAE Systems, the Archerfish vehicle was selected as the Common Neutraliser to equip AMNS, part of the USN’s airborne organic mine clearance capability, is deployed from the MH-60S helicopter and is intended to neutralize bottom, close tethered, and moored sea mines. Meant largely for Hawks deploying on littoral combat ships, they could conceivably be used fleet wide.

In a $8 million sole-source pre-solicitation notice published on 29 January 2014, NAVSEA announced its plan to contract BAE Systems “to produce up to 966 Archerfish Neutralizers (Destructor, Mine Neutralization, Airborne EX 64 Mod 0 Archerfish, EX 65 Mod 0 Archerfish, and EX 66 Mod 0 Archerfish)”, together with fibre-optic spools, neutraliser interface boards, neutraliser interface and deployment packages, and support equipment.

Testing of the Airborne Laser Mine Detection System (ALMDS), another component of the system, started with the LaserHawks of HSC-26 in August 2014

US Naval Sea Systems Command (NAVSEA) this week dropped another $22 million ($56 cumulative) for Archerfish  which should move the ball down the field a bit.

Meet Seagull, Israel’s new USV robot boat

seagull

Elbit Systems has a new 40-foot unmanned surface vehicle, the Seagull, which is designed to operate in pairs for either mine sweeping or sub busting. The idea is the first vehicle will have surveillance gear to find the sub or mine, while the second will carry either clearance gear (an ROV) or a anti-submarine torpedo to shove right up the sneaky U-boat’s kisser.

From Elbit’s presser:

Drawing on world class know -how derived from generations of Unmanned Aircraft Systems (UAS) design, development and operation and its naval capabilities, Elbit Systems’ newest offering in the unmanned platform field is Seagull -an organic, modular, highly autonomous, multi-mission Unmanned Surface Vehicle (USV) system.

Seagull is a 12-meter USV with replaceable mission modules, with two vessels capable of being operated and controlled in concert using a single Mission Control System (MCS), from manned ships or from the shore.

The system provides unmanned end-to-end mine hunting operation taking the man out of the mine field. It provides mission planning, and on-line operation in known and unknown areas,including area survey, search, detection, classification, identification, neutralization and verification. It is equipped to search the entire water volume and operate underwater vehicles to identify and neutralize mines.

The idea is the two-boat pair can operate within 50-100 miles of the control station and remain at sea for 96 hours, covering a pretty large swath of littoral in the process while their operators sip coffee back in a trailer somewhere. A second set of boats can be kept ready to rotate out the first, making a persistent sea station a very possible endeavor.

This obviously has uses in a MIUWU or PSU augmentation or replacement.

Speaking of which, DARPA’s Sea Hunter–the Anti-Submarine Warfare Continuous Trail Unmanned Vessel, or ACTUV is the U.S.’s version of this, and is mucho larger at some 132-feet long and is getting some love on social media as of late.
