Leidos Inc. was awarded a $72.8 million contract for work on submarine detection sonar for the U.S. Navy, the Defense Department announced.

The company, based in Reston, Va., will perform work on the Transformational Reliable Acoustic Path System, or TRAPS, one of two prototypes developed by the Defense Advanced Research Projects Agency, the Defense Department agency responsible for the development of emerging technologies military applications.

Leidos' Leidos' work on TRAPS comes under an indefinite quantity, cost-plus-fixed-fee contract with a three-year ordering period and no options, the Defense Department announced on Friday.

The TRAPS system uses a fixed sonar mode placed on the ocean floor, exploiting advantages of operating from the seafloor, to achieve large-area surveillance of the area surrounding the submarine. Each node communicates back to a floating "stationary surface node" through a wireless acoustic modem when the ocean floor node detects a sound.

The other prototype, called Submarine Hold at Risk [SHARK], has an unmanned underwater vehicle as a mobile platform to track enemy submarines. Both are part of DARPA's Distributed Agile Submarine Hunting [DASH] program.

Leidos' work on the contract will be done at the company's Long Beach, Miss., facility, with an expected completion date of June 2022.

Lockheed nets $16.2M contract for Virginia-class sub masts
Washington (UPI) Jun 24, 2019 - Lockheed Martin's Rotary and Missions Systems division received a $16.2 million contract to build elements of Virginia-class submarines, the Defense Department announced.

The company will manufacture multifunction modular masts for the submarines' Block V hull, which can be extended by sections, depending on the requirements of the vessels' strike capabilities. Virginia-class submarines with Block V armaments are capable of carrying Tomahawk cruise missiles.

The vessels typically carry eight masts, which include a snorkel mast, two photonic masts as replacements for periscopes, high-data-rate satellite communication masts, a radar mast and an electronic warfare mast.

The contract was competitively procured through the Federal Business Opportunities website and announced on Friday. It specifies options which can boost it value to $97.8 million.

Work on the contract will be done at Lockheed Martin facilities in Nashua, N.H., and Syracuse, N.Y., and is expected to be completed by June 2020. If all options are exercised, the deadline will be extended to June 2024.

The Naval Sea Systems Command at Washington Navy Yard in Washington, D.C., was the contracting agent.
