OZ to pick up 12 redesigned SSNs (-N) and upto 450 AMRAAMs

In the ever-continuing West Pac arms race, Australian officials announced this week that France’s DCNS has won the $38.5 billion Project SEA 1000 Future Submarine program to replace six Collins-class submarines currently in service with the Royal Australian Navy (RAN) with a dozen Shortfin Barracuda Block 1A boats.

The Barracudas (Suffren-class in French Naval use) are a sexy batch of nuclear-powered attack subs that are currently building. They are 5,300-ton ships that include advanced features like a pump-jet propeller and X-shaped stern planes. While smaller than the U.S. Virginia-class, they are comparable in size to the old school Sturgeon-class SSNs of the 1970s and 80s and the Los Angeles-class which are still bumping along. They will, naturally, be larger and more advanced that the Collins.

The difference between the Aussie subs and the Sufferns will be that their dozen boats– to be built in Australia– will be diesel boats. They will be able to force-project as needed.

Further, Australia could become the first foreign nation to buy the radar-guided Raytheon AIM-120D air-to-air missile under a $1.2 billion foreign military sales package approved by the U.S. government this week. The Delta has a 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (Pk) and the U.S. military itself is wanting a bunch but they are tied up in sequestration.

Included with that deal is:

Up to 450 Advanced Medium-Range Air-to-Air Missiles (AIM-120D)
Up to 34 AIM-120D Air Vehicles Instrumented (AAVI)
Up to 6 Instrumented Test Vehicles (ITVs)
Up to 10 spare AIM-120 Guidance Sections (GSs)

450 Fox Threes and a dozen of the world’s most advanced SSKs sure make a potent pill against a future enemy looking to roll hard over Canberra.

A-10s in the PI

In other news, the Air Force is rotating composite units of A-10s and HH-60s through the PI and, they are reportedly flying maritime patrols over Scarborough Shoal in the South China Sea. 

“Our job is to ensure air and sea domains remain open in accordance with international law,” said Air Force Col. Larry Card, the commander of the new air contingent in the Philippines. “That is extremely important, international economics depends on it — free trade depends on our ability to move goods. There’s no nation right now whose economy does not depend on the well-being of the economy of other nations.”

Memoratus in aeternum, Thresher

USS Thresher (SSN-593), commissioned in August 1961, was the lead ship of a new class of nuclear-powered, fast-attack submarines and was the most technically advanced ship in the world.

On April 10, 1963, she sank approximately 200 miles off the coast of Massachusetts. All souls aboard were lost that day; 129 U.S. Navy Sailors and civilian workers. Thresher was the first nuclear-powered submarine lost at sea, and the largest loss of life in the submarine force’s history.

As a result of this, the Navy immediately restricted all submarines in depth until the causes of this tragic loss could be fully understood, leading to SUBSAFE.

This week, 53 years on, she is still remembered. This week the U.S. Naval Undersea Museum added to their permanent Thresher display the ceremonial dress sword of LCDR Pat Garner, Thresher‘s Executive Officer when she sank. This is the first time the sword, on special loan to the museum, has ever been exhibited.

“It’s been 53 years since we lost Thresher and out of the loss came the SUBSAFE program,” said Rear Adm. Moises DelToro, deputy commander, Undersea Warfare in a statement. “Our challenge today, 53 years after the loss of Thresher, is to maintain our vigilance, intensity and integrity in all matters involving the SUBSAFE program and to avoid ignorance, arrogance and complacency.”

Speaking of drones in the Pacific

I’ve talked a lot about the Navy’s Sea Hunter program and others, but how about this news ICYMI from the Pitcairn Islands– you know, that windswept group of four volcanic atolls in the Pacific inhabited mostly by descendants of the Bounty mutineers and the Tahitians who accompanied them. Sparsely populated, the British Territory sees the occasional USCG/USN or RN ship pass through the area, but there is no enduring presence.

It seems they have hit on the idea of protecting their huge EEZ (322,000 sq. mile, or about the size of Texas and Montana combined!) by unmanned submersible operated by Satellite Applications Catapult and the Pew Charitable Trusts at the Harwell Science and Innovation Campus in Harwell, Oxfordshire.

_81734919_eyes_on_sea_war_room0

Apparently the preserve is home to at least 1,249 species of marine mammals, seabirds and fish, as well as some of the most near-pristine ocean habitat on Earth, and the 54 inhabitants of the Pitcairnians– who depend on the sea for survival– can’t stop trans-global poachers all by themselves.

From the BBC:

The drone, made by US firm Liquid Robotics, will be directed by staff at the satellite watch room which is monitoring fishing vessels. The craft is equipped with a camera that can take snaps of fishing vessels that are in restricted areas, and satellite technology that can pinpoint their location. The unmanned craft starting patrolling late last month.

The Liquid Robotics drone, called a Wave Glider, is a two-part craft made up of an instrument-bearing boat that floats on the ocean surface that is tethered to a submersible. The craft uses the differential motion between the sea surface and the region the submersible traverses to propel itself.

The self-propelling propulsion system means the Wave Glider can stay at sea for months at a time.

Get your Das Uboote on

Throwback Thursday: The German Bundeswehr posted this groovy six-minute film about the Type 206A coastal diesel boats filmed in 1984. Entitled Stahlfisch (Steelfish) its chock full of really neat operational scenes filmed aboard S176, a handy little 159-foot/450-ton boat which was in commission for 30 years, only being scrapped in 2005.

Of course it’s in German, but all good U-boat films are, right?

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.

A Customs and Border Patrol Air and Marine Office P-3 Orion Long Range Tracker found a self-propelled semi-submersible vessel (SPSS/dope sub) in the Eastern Pacific Ocean that led to the arrest of four smugglers and the boat being lost at sea with 6 tons of blow on board. Street value was $193 milly.

As noted by CBP in their presser:

The crew aboard a P-3 Long Range Tracker detected a self-propelled semi-submersible vessel Mar. 2, while conducting counter-narcotics operations with Joint Interagency Task Force (JIATF) South.

The task force coordinated an interdiction of the semi-submersible with a U.S. Coast Guard vessel in the area while the AMO crew maintained constant visual surveillance. Upon interdiction, the U.S. Coast Guard arrested four individuals operating the vessel.  The semi-submersible became unstable and sank.

“This type of cooperation and teamwork produces these kinds of results where suspects are arrested and narcotics prevented from reaching U.S. shores,” said Director John Wassong at the National Air Security Operations Center – Corpus Christi. “Our crews will continue to take every opportunity to disrupt this type of transnational criminal activity.”

CBP operates two types of P-3s: 11 P-3 Airborne Early Warning, or AEW, and 3 P-3 Long Range Tracker, or LRT, aircraft flying from Corpus Christi, Texas, and Jacksonville, Florida.

CBP’s LRTs, called “slicks” by the service to differentiate them from the AN/APS 145 radar-equipped AEWs, are former USN P-3As that have landed most of their ASW and ASuW suite, replacing them with an electro-optic ball with night vision and FLIR capabilities, APG 66 air search and SeaVue marine search radars used for detecting and tracking targets of interest.

Over 40 years old, the 14 Orions flown by CBP have been extensively reworked in recent years and are expected to remain in service for another two decades.

Warship Wednesday: March 16, 2016, the Tale of the Photogenic Tyrant

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 forward view from the conning tower of the British T (Triton)-class diesel electric submarine HMS Tribune (N76) of HMs Royal Navy running along the surface in Scottish waters, 1942. Though modern and relatively low mileage, this 275-foot fleet boat only served for a decade, but she will live on for eternity.

With the World War I era boats getting long in the tooth, the Admiralty commissioned twelve 275-foot Odin-class, six 289-foot Parthian-class, six 287-foot Rainbow-class, 62 much smaller 202-foot S-class, three huge and rather experimental 345-foot River-class and six 289-foot Grampus-class submarines in the 1920s and 30s. With lessons learned from these 95~ diesel boats, it seemed the brass liked the 275-foot range as a sweet spot for general sub size and pushed ahead with 53 new T-class boats to replace the 1920s era O, P and R class submersibles mentioned above.

These sea monsters, designed in 1935, had an impressive armament of 10 torpedo tubes (6 bow, 4 aft) which was considered devastating at the time, room for 16 torpedoes, and mounted a QF 4-incher on deck. A crew of 48 manned the 1,500-ton smoke boat and twin diesel/electric engines/motors could drive them at nearly 16 knots on the surface and 9 when submerged. They weren’t flashy compared to the German, U.S. and Japanese fleet boats of the day, but they could sail 8,000 nautical miles and could operate at a 300 foot depth with no problem.

The hero of our tale, HMS Tribune, was the sixth and thus far last ship of the fleet to carry that name since 1796. Laid down 3 March 1937 at Scotts Shipbuilding and Engineering Company in Greenock on the River Clyde in Scotland, she was commissioned into the fleet on 17 October 1939– just six weeks after the start of World War II.

While still working up Tribune may have brushed into U-21 thought neither ship exchanged fire.

Over the next three and a half years she would complete an impressive 18 war patrols, though cranky engines proved her undoing. Many of Tribune’s patrols were quiet, with nothing but neutral ships spotted. Covered in great detail over at Uboat.net (go read it!), she had a series of 15 skippers over this period, typically reserve lieutenants. She spent extensive time off the coast of Norway and in the Kattegat while operating from Rosyth but just couldn’t make the hits when needed.

Tribune made unsuccessful torpedo attacks on the German armed merchant cruiser Schiff 33 / Pinguin off Standlandet, Norway; U-56 in the Hebrides; U-138 with 5 torpedoes about 10 nautical miles South-West of Ile de Groix; the German tanker Karibisches Meer in the Bay of Biscay; and finally sighted the heavy cruiser Admiral Hipper and light cruiser Köln leaving the Gimsostrommen and steering towards Hval Fjord in Sept. 1942 but was unable to attack.

During 1942, Admiralty photographers who captured a number of images that endure in the IWM today toured her at Scapa Flow.

Then came the Crown Film Unit who, with a barebones cast and director Jack Lee, cameraman Bill Chaston and cinematographer Jonah Jones with a few WRENs in-tow, filmed the Ministry of Information film “Close Quarters” aboard the vessel.

In the 75-minute film, she was referred to as HMS Tyrant and, while most of the scenes were fleshed out by a full production crew at Pinewood Studio in a superb full-sized model of the submarine, footage of the boat underway and her spaces were retained.

Note the greatly enhanced Jolly Roger of HMS Tyrant!

Transferring to Gibraltar in November 1942, Tribune began patrols in the Med with about the same success she had off Norway. Although she caught some depth charges from a RAF Wellington by mistake, and more from an Italian patrol boat, she did come in handy by landing SOE agents in Corsica in January 1943 and carried out close recon of the Copaiba Bay shoreline from just 1,000 yards or so offshore.

On 10 Jan 1943, Tribune finally drew blood by pumping torpedoes into the Nazi-flagged French merchant Dalny (6672 GRT, built 1914) 15 nautical miles from San Remo, Italy, which had to be beached in order to prevent sinking.

She followed this up later with damaging the German tanker Präsident Herrenschmidt (9103 GRT, built 1932) about five nautical miles South-West of San Lucido, Italy, in March.

With her engines untrustworthy, Tribune was sent back to Portsmouth in April 1943 and spent the rest of the war as a training boat. Placed in reserve in June 1945 even before the war ended in the Pacific, she was transferred to Falmouth in November 1945 then sold to be broken up for scrap July 1947.

As such, Tribune was luckier than many of her sisterships, of whom 16 were destroyed, largely by mines and in scraps with Italian and German subs in the Med. After the war, some were modernized similar to the same program as the USN did with the GUPPY boats, but the last of these, HMS Tabard (P342), was discarded by 1974.

The stills and movie reels taken of Tribune will continue as a tribute to the class and HMs submarines as a whole during the war.

Meet the new Echo Voyager unmanned underwater vehicle

We all live in a yellow submarine...

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.”

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.

seagull 2 sea gull 3

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.

One of the Kaiser’s boats no longer unaccounted for

When SMS U-31 of the Kaiserliche Marine‘s IV Flotilla sailed from Wilhelmshaven on 13 January 1915, and disappeared shortly thereafter, it was assumed, she had struck a mine and sunk with all hands, somewhere in the North Sea.

Well, it turned out they were right.

Now, 101 years after her disappearance, her final resting place is known. In 2012 an engineering team plotting the site of a new offshore wind farm about 55 nautical miles off the coast of East Anglia found a wreck on the ocean floor.

Digital scan of the sunken U boat, which has been found off the East Anglian coast. See Masons copy MNWRECK: The wreckage of a First World War German submarine has been found by divers 90km off the East Anglian coast. Video footage shows the sunken U-boat, which went missing 1915, on the sea bed under about 100 feet of water. The submarine, which had more than 31 crew onboard, is believed to have hit a mine about 55 miles off Caister on Sea in Norfolk. The 58 metre long wreck was found by a survey team from energy companies Scottish Power Renewables and Vattenfall, who are currently drawing up plans for the new East Anglia ONE wind farm.

Initial investigation thought it to be a lost Dutch sub from the WWII-era, so the Dutch Lamlash wreck-diving team was called in last year and they have identified the vessel as U-31.
