DARPA drone ship tracks submarines – Video Clip

DARPA – the Defense Advanced Research Projects Agency – is known for designing a variety of high-tech and futuristic platforms for the US military.

One of the most recent projects from DARPA? An oceangoing drone ship specially designed for submarine hunting by engineers at SAIC.

The ship – dubbed the ACTUV sub-tracking drone – is specifically built to monitor very quiet diesel-electric submarines. In terms of real-world scenarios, the Navy would deploy sonar buoys around a specific area to give the drone ship an idea of where to search.

After the search area is defined, the drone ship would be capable of taking over the search using long-range and short-range sonars for up to 13 weeks at a time. The ship is also able to detect and gauge the intent of other ships in its path, with human failsafes built into the system.

The ACTUV is currently categorized as a work in progress, so it will be years before the vessel is actually ready to plow through the oceans searching for enemy submarines.

SAIC says the ship won’t requires human interaction or maintenance for the entire term of its 60 to 90 day deployment. Indeed, the only time human assistance is needed during the ACTUV mission is when the harbormaster escorts the ship out of the dock.

ROV submarine finds wreck of bullion liner sunk by WW2 U-32

On 28 October 1940 U-32, under the command of Hans Jenisch, sank the 42,348-ton liner Empress of Britain, which had been previously damaged by German bombs. Empress was the largest ship sunk by a U-boat. U-32 was sunk northwest of Ireland, in position 55°37′N 12°19′W, by depth charges from the British destroyers HMS Harvester and Highlander on 30 October 1940. Nine of her crew died, 33 survived and were taken prisoner, including Jenisch, who spent six and a half years in British captivity before returning to Germany in June 1947

AN Irish-built robot submarine has shed new light on the biggest passenger ship sunk by a German U-boat.

The 42,000-ton Empress of Britain was carrying gold worth millions of euro when it was sunk on October 28, 1940, off Bloody Foreland in Co Donegal.

A 1995 expedition reported finding the Empress upside down in 500ft of water.

The salvagers broke into the ship’s strong room only to find a single skeleton — but no gold.

Now a survey by a Marine Robotics Team from the University of Limerick (UL), using a “Smart” remotely operated vehicle (ROV), has discovered the ship is actually on its side.

The Empress of Britain was hit by two bombs from a Luftwaffe Condor on October 26, 1940 and caught fire about 70 miles northwest of Aran Island, Co Donegal.

Most of the 578 survivors were picked up by British ships, while the liner continued under tow to the Clyde in Scotland.

However, a German submarine, the U-32, shadowed the salvage convoy for nearly 24 hours before firing three torpedoes.

Two hit and sank the Empress northwest of Bloody Foreland. Some 25 crew members and 20 passengers were killed when she went down.

The gold is now thought to have been taken off the ship while it was on fire and its passengers were being evacuated.

Iran Almost Through with Indigenization of Submarine Technology

A senior Iranian defense industry official announced on Monday that the country has almost completely indigenized building of military submarines.

Deputy Head of the Naval Industries Organization of the Iranian Ministry of Defense General Babayee said Iran can now manufacture different types of naval equipments, including submarines.

“In construction of military submarines, this organization has achieved more than 90% indigenization now ,” Babayee said.

As regards other products, the official said, “We have indigenized some products up to 92%, while with regard to the production of some other products and depending on the type of the project, indigenization has taken place from 65 to 70%.”

Last month, Iran boosted its naval power in Persian Gulf waters after a new missile launching vessel and two light submarines joined its Navy fleet.

During the ceremony attended by Iranian Navy Commander Rear Admiral Habibollah Sayyari, two Qadir-class light submarines also joined the Iranian naval fleet.

All parts of the Qadir-class submarines, including the hull, radar equipment and advanced defense systems, have been made domestically.

The submarines are appropriate vessels for different naval missions, including reconnaissance and combat in territorial waters, specially in the Persian Gulf and the Strait of Hormuz which are not wide enough for the maneuvering of large warships and submarines.

Meantime, the Iranian Navy tested the operational capabilities of its submarine units on the second day of Velayat 91 naval wargames on Saturday.

Spokesman of the Wargames Rear Admiral Amir Rastegari announced that on the second day of the drills, Iran’s light and kilo-class submarines have traversed the territorial and international waters, conducted reconnaissance missions and traced hypothetical enemies successfully.
