The U.S. Navy awarded BAE Systems San Diego Ship Repair a contract to perform depot-level maintenance and alterations to the USS Bunker Hill, the oldest Ticonderoga-class cruiser in the fleet. The deal is not to exceed $38.3 million. Work is expected to be complete by May of 2016.

The Navy’s Southwest Regional Maintenance Center of San Diego awarded the contract, announced on July 21.

Cruisers carry Tomahawk cruise missiles and take part in air warfare, undersea warfare, naval surface fire support and surface warfare; some have been outfitted for ballistic missile defense. The first five ships in the class — the Ticonderoga included — have been decommissioned.
