The U.S. Navy said it has awarded Carlsbad-based ViaSat Inc. a three-year, $12.3 million contract to repair MIDS radios used on various aircraft platforms.

MIDS is short for Multifunctional Information Distribution System. The system carries voice and data traffic.

The Naval Supply Systems Command Weapon Systems Support activity of Philadelphia awarded the deal.

The contract was not competitively procured because the buyer deemed the service was available from only one reliable source or from a limited number of reliable sources.
