  Navy issues $23.4M contract for Block 5 Virginia-class sub hardware

  The Virginia-class contract was issued to Lockheed Martin, days after General Dynamics was awarded a $22.2 billion deal for nine of the next generation submarines. ByChristen McCurdy Dec. 6 (UPI) -- Lockheed Martin Rotary and Mission Systems received a $23.4 million deal to procure hardware for Virginia-class submarines, the Department of Defense announced Friday. The contract funds the purchase of long-lead-time material for two Virginia Block 5 hulls, one Virginia installation and checkout kit, one pre-production unit and associated hardware assets for testing, according to a press release. On Tuesday, General Dynamics Electric Boat received a $22.2 billion contract to build nine Block 5 subs for the Navy. Virginia-class submarines are built to conduct anti-submarine warfare, anti-surface-ship warfare, strike warfare and special operations support as well as intelligence, surveillance and reconnaissance. Block 5 submarines have an additional payload module and more payload tubes for launching cruise missiles. Work will be performed in Syracuse and is expected to be completed by December 2020. https://www.upi.com/Defense-News/2019/12/06/Navy-issues-234M-contract-for-Block-5-Virginia-class-sub-hardware/1391575679260

  New undersea drones are smaller, cheaper and can be refueled deep under water

  By: Victoria Leoni NATIONAL HARBOR, Md. — Bright yellow underwater drones were a visible highlight on the exhibition floor here at the Sea-Air-Space Exposition. Among the autonomous underwater vehicles (AUVs) featured: a new high-speed, micro-sized vehicle by Hydroid and a subsea drone refueling station by Teledyne Energy. Hydroid's Remus M3V is substantially smaller than previous models. With a compact, A-size (36-inch long, 4.875-inch diameter) envelope and no fins or appendages, the vehicle can achieve speeds of more than 10 knots and dive up to 300 meters. It can be used in search and survey; intelligence, surveillance and reconnaissance (ISR); and multivehicle missions. With its variable center of gravity, the Remus M3V can also operate in buoy mode. Its key marketing points are its small size, low cost and compatibility with existing AUV operating systems. “The Navy always wants more with less,” said Justin S. Reid, business development manager at Hydroid. “They want a smaller vehicle that can do the same things as a larger vehicle, and also the price point to match it.” Teledyne Energy featured its untethered subsea power station at the exposition, along with its Gavia AUV. The Gavia can perform side-scan sonar operations to capture images of the sea floor. It is intended to travel ahead of Navy fleets and transmit oceanographic data back to the vessels. Teledyne's subsea power station can remotely refuel the Gavia and other underwater vehicles. Deployable via ship or helicopter, the fuel cell system has an energy storage of 200 kilowatt-hours and an operating depth of 3,000 meters. Teledyne will demonstrate the subsea power station at the Navy's Advanced Naval Technology Exercise in August.
