Viasat Inc. said June 21 that it received a U.S. Air Force contract to sustain MIDS-LVT radios.

The indefinite quantity deal — covering repairs, spares and support services — could be worth as much as $42 million over five years. The deal covers domestic and foreign military sales. Work will be performed in Carlsbad.

Viasat (Nasdaq: VSAT) said it currently has more than 3,500 MIDS-LVT units fielded to 20 customers worldwide. The initials stand for Multifunctional Information Distribution Systems Low Volume Terminal.

MIDS-LVT units are part of the tactical Link 16 radio communications system meant to provide soldiers and pilots greater situational awareness by exchanging digital data over a common communication link. Link 16 is continuously and automatically updated in real-time. According to Viasat, that reduces the chance of fratricide or duplicate assignments, while increasing mission effectiveness.

The Air Force Sustainment Center at Robins Air Force Base in Georgia awarded the contract.
