NORFOLK, Va. (NNS) -- The fast-attack submarine USS Scranton (SSN 756) successfully demonstrated homing and docking of an Unmanned Undersea Vehicle (UUV) system during at-sea testing in January 2006.

The two UUVs used in the testing are a part of the AN/BLQ-11 Long Term Mine Reconnaissance System (LMRS), which was designed to enable submarines to conduct clandestine undersea surveys to locate mines.

“The testing demonstrated several important capabilities of a submarine-launched UUV system,” said Capt. Paul D. Ims Jr., program manager for UUVs in the Program Executive Office for Littoral and Mine Warfare. “These included the ability of the submarine to prepare and then launch an autonomous UUV from her torpedo tubes, and the ability of the submarine to rendezvous with an autonomous UUV and then control the UUV with an underwater acoustic communication system.”

According to Ims, repeated homing tests were conducted with slightly different configurations to assess the ability of a UUV to dock with a torpedo-tube-mounted recovery system. The final result was the first successful docking of the LMRS vehicle to a submerged submarine at-sea.

“This was a big step forward,” Ims said. “The Navy is making significant progress in the development of Unmanned Undersea Vehicles, especially in the mission areas of reconnaissance, surveillance and anti-mine warfare.”

“Our UUV programs are focused on delivering more affordable, modular, autonomous systems with an open architecture.”

After the UUV is launched from the submarine’s torpedo tube, it transits to a series of pre-programmed waypoints. Meanwhile, the submarine maneuvers to rendezvous with the UUV. Homing and Docking sonar guides the UUV towards the recovery arm, a unique docking mechanism that extends out of the ship’s upper torpedo tube. After the UUV is captured, the recovery arm guides the UUV into the lower torpedo tube, and back into the submarine.

“Achieving the first successful at sea docking of an autonomous UUV with a submarine was the result of a seamless joint effort between Scranton and the LMRS team,” said Cmdr. Mike Quinn, commanding officer, Scranton. “Submarine missions are increasingly focused on generating real-time, actionable intelligence and the ability to launch and recover autonomous, re-useable UUVs with various mission payloads will improve our ability to provide the theater commanders with the information they need to successfully conduct pre-cursor, as well as combat operations.”

“Improvements in autonomy -- the artificial intelligence that enables UUVs to function beneath the water for long periods of time without communication with human operators -- will enable UUVs to accomplish very sophisticated missions with complex payloads,” Ims added.

The LMRS test demonstrated technologies possible from completely autonomous UUVs. Once launched, there are no wires connecting them to the submarine. The UUVs can monitor and control their position using sophisticated inertial navigation systems and GPS receivers. Forward and side scanning sonars enable obstacle avoidance, and communications are accomplished via acoustic and UHF satellite communications systems.

An average of 10 attack submarines are deployed globally at any given time, performing a variety of missions in support of national security and the global war on terrorism. UUVs are just one of the multi-mission payloads submarines bring to the joint warfighting arena.

“Unmanned Undersea Vehicles will extend the submarine's stealthy reach, across both the depth and breadth of the littoral battlespace,” Ims stated. “Acting as a clandestine, autonomous, mobile sensor, networked into the Global Information Grid, UUVs will provide unprecedented improvements in battlespace awareness.”

The variety and complexity of missions that a UUV can perform will provide the area commanders a valuable tool in Intelligence, Surveillance and Reconnaissance (ISR) and other littoral operations.

“UUVs will play a major role in assuring access to the littorals and enabling U.S. Joint Forces to project power from the sea to inland objectives,” Ims said.

“Mine Countermeasure and ISR mission capabilities will be delivered first, followed by expansion into other warfighting missions through development of modular payloads,” he added. “UUVs will provide the submarine force with access to littoral battlespace that is too shallow for submarine operations or is otherwise inaccessible.”

“With FORCEnet connectivity, UUVs will be a force multiplier, enabling a single submarine to simultaneously provide clandestine presence in multiple locations.”

Several critical lessons were learned during these tests, including management of the interaction that occurs when a UUV comes very close and then docks to a submerged submarine, the integration of UUV systems within the submarine and the performance of UUV acoustic communication and homing systems.

All of these lessons learned are being used to continue the development of UUVs for today’s submarine force and looking at future capabilities and technologies for the next generation of UUVs.

“Advances in autonomy software, energy systems, sensor design and computer processing technology will make it possible to pack ever-increasing capability into smaller, cheaper UUVs,” Ims explained.

“These improvements will also enable a UUV of a given size to have longer endurance or carry more payload,” he continued. “Unmanned vehicle systems must employ modular hardware and software design, and an open system architecture that will support rapid, affordable insertion of new technologies and payloads.”

“The follow on applications for this technology and capability in the submarine force are limitless,” Quinn added.

Up-Periscope!!

[L98Fiero]

Now that's a pig-boat.

[Southack]

UUV's are as cool as UAV's...maybe cooler.

[martin_fierro]

Meanwhile, in Iran...

[Casekirchen]

Its bad enought that we have a submarine named for Jimmah.

Do we also have to have one named for a democratic senatorial candidate in Pennsylvania as well?

[Paul Ross]

Bump!

“UUVs will provide the submarine force with access to littoral battlespace that is too shallow for submarine operations or is otherwise inaccessible.”

Finally. I hope this will help us maintain the balance in the Straits of Taiwan... Anti-mine, ISR, and presumably, a platform for anti-submarine, and anti-shipping operations.

The Chinese subs are getting much better...and we are looking likely at air-independent systems for their conventionals...

[MEG33]

Good News!

AN/BLQ-11

Very cool tool

[mylife]

Go to WWII sonar school Here!

[mylife]

Its actually ASW sonabouy ops but its pretty cool

[Grampa Dave]

Go Navy.

Of course according to the old submariner, Jimmy Carter, who banged his head too many times while in the boat, there is no real need for this new submarine. Only Bush and a strong America are dangerous to the world.

[SandRat]

and anyone who's read about Adm Rickover knows you only left his Nuke Sub Navy when your obligation was over or you screwed up. Since the Peanut Farmers obligation was not over that only leaves the later.

"anyone who's read about Adm Rickover knows you only left his Nuke Sub Navy when your obligation was over or you screwed up. Since the Peanut Farmers obligation was not over that only leaves the later."

Interesting in that I was told this by a friend whose company does special retro jobs on subs just a few weeks ago. He had been told this and recently read a book on our nuclear subs. At that time no one as an officer got into his Nuc Sub Navy as you note w/o Rickover's approval. Also, if you left before your obligation was over as you noted, Rickover wanted you out of his program.

Thanks for the good post. On a related, "secret report."

More US subs to counter Chinese threat

THE United States Navy plans to secretly transfer submarines from its Atlantic to Pacific fleet, reflecting an increased awareness of the potential threat China could pose to future world security.

The plan, to move six submarines to the Pacific by 2010, will leave 60 percent of the US Navy's submarine fleet in the Pacific and 40 percent in the Atlantic. Currently, the submarines are evenly divided between the two oceans.

Hawaii's Pearl Harbour base will gain one submarine to boost its total to 18, San Diego would see its submarine force grow to seven from four. Bremerton, Washington state, will gain two more subs for a total of three, according to an unidentified US Navy official.

Navy bases in Norfolk, Virginia, and New London, Connecticut, will lose ships.

Thanks for both pings. One wonders if Jimmy Carter was a paid consultant in the building of the new Iranium sub?

[george76]

Adm. Rickover knew Jimmah was not capable.

We know that Jimmah is not capable.

If Jimmah helped the Iranians, then their boat may sink on its first dive.

Is that the Captain in the white helmet or the crew?
