Ceradyne, a 3M-owned manufacturer of advanced ceramic systems and components has been awarded a $92.7 million Defense Logistics Agency contract to produce improved small arms protective inserts for the U.S. military, the U.S. Department of Defense announced Wednesday.

The inserts are a form of ceramic trauma plate added to ballistic vests. The U.S. Army, Navy, Air Force, and Marine Corps will all benefit from the addition. The sole-source acquisition contract is for one-year and 10 months with no options included. The labor will be conducted in California and Kentucky and should be finished on Nov. 30, 2017.

General Dynamics Electric Boat is being awarded a change to a Navy contract for the development of conformal acoustic velocity sonar large vertical array outboard electronics. The alteration will increase the value of the undefinitized contract action modification to $8.3 million. The labor will be conducted in Groton, Conn., and should be finished by October 2018.

Electric Boat was also awarded a $7.1 million modification to a Navy contract to restructure a main propulsion machinery and ship service turbine generator control system for submarines. More than $3.5 million in fiscal 2016 funding will be assigned at the time of the award, none of which will expire at the end of the fiscal year. The work will be conducted in Groton, Conn., and should be finished by March 2017.
