Chairman and chief executive officer John F. Sullivan Jr. of Bath (Maine) Iron Works announced recently the shipyard has been awarded a contract for $4.9 million for additional work on four FFG7-class guided missile frigates (FFG-20, 22, 28 and 31) built by Todd Shipyards on the West Coast, but scheduled to be homeported on the East Coast.

The initial contract price covers all work to be done on the FFG-20 and advance planning, design work and material procurement for the remaining three ships.

The Post Shakedown Availability (PSA) work includes modification of combat systems, installation of improved early warning systems, habitability modifications and the updating of the other ships' systems.

The USS Antrim, FFG-20, is expected to arrive at Bath on May 7, 1982 for a 14-week PSA period.
