BAE Systems San Diego Ship Repair is among seven companies awarded second-year contract options on U.S. Navy ship modernization deals.

Up to $117.3 million worth of work may be split among BAE and six other vendors. The contracts are indefinite delivery, indefinite quantity deals, so the vendors will need task orders from the Navy to proceed.

The contracts cover continuing engineering and technical services to modernize Navy ships. The seven contractors will upgrade, repair and maintain what the Navy calls HM&E systems (short for hull, mechanical and electrical systems). Work is expected to last through March 2018.

The Naval Surface Warfare Center of Philadelphia awarded the contracts. The Navy announced the awards Aug. 12.

Other companies receiving similar contracts were L3 Unidyne Inc., Epsilon Systems Solutions Inc., Delphinus Engineering Inc., General Dynamics Information Technology Inc., Q.E.D. Systems Inc. and Amsec LLC.
