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.

“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.

Almost always retrieved after tests or exercises, they are refurbished and shot again, sometimes dozens of times.

If not recovered by retrieval personnel for some reason, they have a ‘phone home’ marking on the casing should a random skin diver or fisherman chance upon one.

Everything old is new again

Response Boat Small, Generation two (RBS-II)

You are looking at the maiden voyage of the new CG29247, a Response Boat Small, Generation two (RBS-II), at U.S. Coast Guard Station Apra Harbor, Guam, the Western-most USCG base in the world.

The RBS-II has an offshore racing hull design with trim tabs and was the competition winner by Metal Shark with their 29-foot Defiant-series deep V aluminum-hulled boat. The company won a $192 million contract in 2011 for (upto) 470 of these vessels to be used at Coast Guard stations as by large ocean going cutters. So far, 180 of 224 boats ordered and paid for have been delivered. Another 20 boats may be ordered by CBP and up to 10 by the U.S. Navy.

They are replacing the 400 remaining 25-foot SafeBoats Defender-class RB-S vessels– since 2001 the most common vessels in the Coast Guard, used by sectors, stations, MSRT/MSSTs, MSUs, training centers, and some AUXFACs.

However, the Defenders, the last of which were delivered in 2009, ironically replacing a myriad of aluminum-hulled Boston Whalers and RIBs used by the Guard, only have a 10-year lifespan as their hull/electronics and outboards all time out about the same.

The ‘Sharks have drop down windows for all-weather use, can pack upto 600 HP of outboards or twin Yanmar 6LPA-STP2 diesels mated to Hamilton 241 jet drives, have shock-mitigating seats just like the Navy’s SWCC boats, glass cockpits, can mount M2/M240s on two different towing points that double as pintle bases, surface search nav radar and lots of other neato features.

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.

The Outer Banks, via 47 foot MLB

The Coast Guard’s 47 foot Motor Life Boat, introduced years ago, is much more advanced than the 41 and 30 foot motor life boats, is still a wild ride. (And show up on the surplus market from time to time)

From the Makapu’u Light on Oahu’s southeastern most point, the world’s largest lighthouse lens reflects a beam that can be seen from 19 nautical miles away.

The 12-foot-tall and 8-foot-wide Hyper-radiant Fresnel lens takes up more than a quarter of the space inside the 46-foot-tall lighthouse.

With more than a thousand prisms, the lens is almost five feet taller than the First Order Fresnel lens in America’s tallest lighthouse, the 207-foot-tall Cape Hatteras Light in the North Carolina Outer Banks. It is wide enough for several people to stand inside.

“It is, by far, the largest lens that I have ever seen,” said Chief Petty Officer Ernest W. Rucker, who leads the Honolulu-based U.S. Coast Guard Aids to Navigation Team (ANT) that maintains the lens.

The Hyper-radiant lens was unveiled at the 1893 Chicago World Fair. Once it reached Hawaii, pieces of the giant lens were hoisted from a moving ship up the steep lava slope and reassembled in the lighthouse.

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.

PI to start receiving first of 10 new patrol boats, wants to go bigger

44m opvThe Japan Marine United Corporation is currently building a class of 10 new 44m (144-foot) offshore patrol vessels for the Philippine Coast Guard (PCG), paid for in part by Japanese grants. These ships, nice slow patrol boats dubbed “Multi-Role Response Vessels” with long enough legs to keep a presence in the disputed South China Sea, are just what the PI needs. And of course, since a lot of the money comes from Japan, the program allows the Philippines to act as an increased buffer by proxy with China.

Japan_Coast_Guar_MRRV

The first of these will arrive in the Philippines in September and the type is already in use with the Japanese Coast Guard.

Further, the PCG is looking at two follow-on 92m (302-foot) vessels and hire another 900 coasties.

This, coupled with the fact that the flagships of the Philippine Navy are a pair of retired 378-foot Hamiliton class USCG Cutters, could lead one to wonder just who is the bigger sea service in the Philippines in the next few years.

But of course, that is all part of the chess game with China, as they are ordering huge “Coast Guard” ships themselves pushing 15,000-tons, or the size of a WWII heavy cruiser.

Reports state that these ships will be able to hit 25 knots and will be outfitted with 76mm naval cannons, two secondary gun turrets, two anti-aircraft CIWS mounts as well as being able to carry at least a pair of large Z-8 multi-role helicopters. These helicopters, somewhat akin to a CH-53 Stallion, could move a lot of personnel and material very quickly without a port available.

In addition, Japan is building at least two more 9,000-ton (the size of an Aegis destroyer) Shikishima Class coast guard cutters for their own racing stripe service. So we are in effect looking at a Coast Guard race in the Far East.

Congress finally approved both a polar and another Great Lakes icebreaker

If you have read this insipid blog long enough you know that I am a fan of icebreakers (the ships, not the chat-up)  and bemoaned the long-running lack of such vessels in U.S. maritime service.

Well it seems Congress is finally doing something about it.

The Coast Guard Authorization Act of 2015  passed by voice vote in the U.S. House of Representatives on Monday, Feb. 1, approving a bill the Senate passed in December. It now moves to President Barack Obama’s desk for a signature.

As part of the $1.9 billion included with the bill is money for a new polar icebreaker and one for the Great Lakes.

“This bipartisan bill authorizes the Coast Guard for two years and strengthens its ability to recapitalize an aging fleet of cutters and aircraft that are decades past their prime,” said Rep. Duncan Hunter, R-California.

Now hold your breath and wait for the ships to pop out, which may be a totally different thing altogether.

And so goes the Viking

After over 40 years in service to the Navy, the humble and often unloved S-3 Viking has passed on. This neat little ASW bird was cooked up in the 1970s to replace the aging S-2 Tracker prop plane to give the Navy’s carriers persistent sub-busting and surface control capabilities without having to task a P-3 squadron to each flattop from shore.

While the S-3 never had to actually drop it hot on a Russki sub, they tracked hundreds of them and would have been one of the vital keys to keeping the Atlantic open if the Cold War ever went hot. Post-1989, they were increasingly used (as the P-3 was/is) in supporting overland operations, providing vital eyes and ears in EW recon roles as well as helping the fleet with light COD and aerial refueling (buddy stores).

S-2 Turbo Tracker peels off from an S-3 Viking.

An S-2 Turbo Tracker of VS-21 hands it off to the then-new S-3. The last Navy S-2 was withdrawn from service on 29 August 1976

During the Gulf War, Vikings nailed a number of Saddam’s small fast attack craft as well, proving their teeth worked just fine.

Now, retired from the main fleet in 2009, a number of S-3 aircraft joined Air Test and Evaluation Squadron (VX) 30 and continued to be used for range control duties out of Point Magu where they were appreciated.

From the Navy’s presser

“It’s got legs,” Capt. John Rousseau, who led the charge to bring the retired aircraft to VX-30. “It can go fast and long. The radar, even though it’s old, there’s not many better. We still spot schools of dolphins and patches of seaweed” when patrolling the range.

In November, VX-30 retired the first of its three Vikings, flying it to the military aircraft boneyard at Davis-Monthan Air Force Base in Arizona. The other two, each with 40 years of service on the airframe, were not far behind.

“They still have life in them,” Rousseau said, “but it was time for another depot-level maintenance period, and you have to weigh that cost against the little time you could still get out of them.”

And with that, the last two were pulled off line this month and are headed to the desert.

And maybe Taiwan who could use them to replace (wait for it) 1950s vintage S-2 Trackers.

Other ideas to re-purpose the old “turkey bird” is as a dedicated COD aircraft or even an unmanned carrier-based drone.
