Lockheed has been awarded a contract for the production of mod 7 common broadband advanced sonar system (CBASS) functional item replacement (FIR) kits.

The $50.6m fixed-price incentive, firm-fixed price, cost-plus-fixed fee contract includes options which, if exercised, would bring the cumulative value of the contract to $235.2m.

The mk48 mod 7 kit production programme will supply the US Navy with FIR upgrade kits consisting of a guidance and control box, broadband analogue sonar receiver, preamplifier, cable assemblies, as well as guidance and control materials.

The CBASS programme will provide the mk48 ADCAP mod 6 torpedo with a wideband sonar system, and advanced broadband signal processing algorithms for enhanced detection and prosecution of shallow water threat targets.

Work will be carried out at the company’s facilities in Massachusetts and Ohio, US, and is expected to be completed by May 2014.

The US Naval Sea Systems Command will be the contracting activity.
