Raytheon reported that DARPA has received the prototype of a new underwater submarine detection system to be mounted on unmanned trimaran hulls.
The Pentagon’s Defense Advanced Research Projects Agency (DARPA) has received the prototype of a new underwater submarine detection system to be mounted on unmanned trimaran hulls, Raytheon said in a news release.
“Raytheon Company has completed delivery of its latest… fifth-generation hull-mounted sonar system, for… DARPA’s Anti-Submarine Warfare Continuous Trail Unmanned Vessel program,” the release, issued on Wednesday, stated.
A prototype trimaran built by Leidos is designed to serve as the program’s unmanned vehicle, Raytheon explained.
The Raytheon report followed published claims that Russia is apparently developing an underwater drone that will be able to inflict massive damage to coastal areas as part of a top secret project known as Ocean Multipurpose System: Status-6 carrying a torpedo equipped with a nuclear warhead.
This weaponized drone will be capable of causing “assured unacceptable damage” to an enemy by contaminating vast coastal areas, rendering them completely unusable for long periods of time, and will be able to bypass NATO’s missile defense system.

China is building some “fairly amazing submarines” and now has more diesel- and nuclear-powered vessels than the United States. China is also expanding the geographic areas of operation for its submarines, and their length of deployment. For instance, China had carried out three deployments in the Indian Ocean, and had kept vessels out at sea for 95 days.
U.S. military officials in recent months have grown increasingly vocal about China’s military buildup and launched a major push to ensure that U.S. military technology stays ahead of rapid advances by China and Russia.
The quality of China’s submarines is reportedly lower than those built by the United States, but the size of its undersea fleet had now surpassed that of the U.S. fleet. A spokeswoman said the U.S. Navy had 71 commissioned U.S. submarines. U.S. submarines are built by Huntington Ingalls Industries Inc. and General Dynamics Corp.
In its last annual report to Congress about China’s military and security developments, the Pentagon said China had 77 principal surface combatant ships, more than 60 submarines, 55 large and medium amphibious ships, and about 85 missile-equipped small combatants.

COTS stands for commercial off-the-shelf stands for commercial items and available in the commercial marketplace that can be bought and used under government contract. Motivations for using COTS components include hopes for reduction of overall system-development and costs (as components can be bought or licensed instead of being developed from scratch) and reduced long-term maintenance costs.
Now COTS computer equipment for sonar signal processing designed by General Dynamics Corp. will be introduced to to US Navy submarines.
A $47 million dollars were granted to the company to deliver Multipurpose Processor (MPP) engineering services and Total Ship Monitoring Systems (TSMS) for Ohio-class missile submarines as well as on Los Angeles-, Seawolf-, and Virginia-class fast attack submarines. The goal of the Naval Sea Systems Command is to increase effectiveness of the following:
- towed array
- hull array
- sphere array
- sonar signal processing
The MPP is a multi-array interface receiver that provides signal conditioning for received array signals; data processing; digital formatting of data; beam formation; and signal processing for A-RCI display data.
The TSMS, meanwhile, monitors and localizes the submarine’s own noise sources including transients, so onboard sonar systems can compensate for it and improve its ability to detect and identify sound emissions from other submarines ad surface ships. The TSMS feeds its data to the MPP.
A 20-year-old “genius” electronic engineer and his father are among the crew searching for the missing Malaysian flight MH370.
When Jay Larsen, the chief engineer on MH370 search vessel GO Phoenix, needed a new technician, his 20-year-old son Kolter sprang to mind.
“He’s an electrical engineer genius and we asked him to come along,” he said.
“He’s been a very solid member. I’m proud of him.
“I don’t know that we can understand the weight of what we’re doing honestly.
“We’ve all experienced losses close to us and we’re out here trying our hardest.”
Jay and Kolter are key members of a search crew on board the GO Phoenix, a vessel scouring the Indian Ocean for the missing Malaysian Airlines Flight 370 (MH370), which disappeared March 8 while ferrying 239 passengers and crewmembers from Kuala Lumpur, Malaysia, to Beijing, China.
And while the Flathead Valley natives long to be home tracking elk sign through the wet November snow, the significance of their contribution to the search expedition isn’t lost on either of them.
For seven months, family members of the missing passengers and flight crew have been waiting for answers buried in a watery abyss, and Larsen hopes his highly specialized sonar technology can help bring them to light.
Jay Larsen owns the Whitefish-based deep-sea survey company Hydrospheric Solutions LLC (HSI), and, as chief engineer of the sonar kit that the ship is towing miles beneath the ocean surface, he has spent the last month mapping the undulating mountains and crevasses of the ocean floor, working round-the-clock to locate the missing flight in the remote southern Indian Ocean. His son, Kolter, an engineering student at Montana State University – Jay’s alma mater – joined the crew somewhat serendipitously as an electrical technician while taking a semester off college.
The sonar that HSI is towing 3.2 miles beneath the ship is called the SLH ProSAS-60, owned by SL Hydrospheric LLC, a company that Larsen still co-manages and co-founded in 2008 with the purpose of bringing the rarefied device to the deep-sea surveying market.

The US Navy’s newest and biggest toy is the imposing Zumwalt-class guided-missile destroyer, a svelte, stealthy entry designed to complement the Navy’s large fleet of Arleigh Burke-class DDGs.
Considering everything from its stealthy figure – which allows it to appear on radar as the same size as a fishing boat – to its 155-millimeter (six-inch) Advanced Gun System represents a significant leap forward in naval technology, it’d be impossible for us to recap all the significant features on this new ship.
Thankfully, Defense News has a really thorough and feature-laden story on the lead ship of the class, theUSS Zumwalt. Covering the ship from bow to stern, anything you might want to know (and that’s been released to the public) about this new destroyer can be found there. Head over and have a look!
A Malaysian navy vessel fitted with specialised sonar equipment has set sail for the Indian Ocean to join in the search for Malaysia Airlines flight MH370 that went missing nearly five months ago.
Defence Minister Hishammuddin Hussein said the KD Mutiara vessel left a navy base on Monday in the north-eastern state of Perak.
The vessel has sonar equipment that can detect objects down to 7,000 meters from the sea surface, he said.
A Chinese ship and an Australian-contracted private vessel are conducting a survey of the Indian Ocean floor where the aircraft was believed to have crashed off the coast of Western Australia.
It vanished without a trace on March 8 about an hour after takeoff from Kuala Lumpur.
Malaysia has vowed to continue the search for the missing flight until the aircraft is found.
The plane was carrying 239 people aboard the flight to Beijing when it radically changed course and the tracking instruments were shut off.
Aviation specialists have surmised that it flew south over the ocean, and would have run out of fuel.
A deep-sea research sub has been lost in Kermadec Trench, one of the ocean’s deepest spots, which lies northeast of New Zealand, media reports said Tuesday.
The unmanned robotic vessel, called Nereus, went missing on Saturday while exploring the Kermadec Trench. It was a flagship ocean explorer for the U.S. science community.
Surface debris was found, suggesting the 8 million dollar sub suffered a catastrophic implosion as a result of the immense pressures when it was operating some 10km down. The deep trench has pressures of about 16,000 pounds per square inch(psi).
“Nereus helped us explore places we have never seen before and ask questions we never thought to ask,” said biologist Timothy Shank from the Woods Hole Oceanographic Institution, which managed the sub.
The robot was built in 2008 and could operate in an autonomous mode or remotely controlled via a tether to a support ship to explore the Earth’s deepest oceanic trenches. The team is now collecting surface debris in hopes of revealing more about the implosion.
