10 -- COMMON BROADBAND ARRAY SONAR SYSTEM (CBASS) SOL N00024-98-R-6107 POC Renee Brooks (SEA02611B) (703) 602-7706 This announcement is to modify the synopsis published on 07 August 1997 which stated the Naval Sea Systems Command's intent to negotiate a sole source contract with Northrop Grumman Corporation, Electronic Sensors and Systems Division for the development of the Common Broadband Advanced Sonar System (CBASS). The CBASS will provide the hardware and software required to implement a broadband sonar system in the ADCAP torpedo. This hardware will include new and modified broadband capable components including the sonar array, sonar analog receiver, preamplifier, and transmitter. Based on a review of the requirements and responses to the synopsis published on 07 August 1997, NAVSEA currently plans to award this contract following a limited competition between Hughes Aircraft Corporation, Naval and Maritime Systems, P.O. Box 3310, Fullerton, CA 92834-3310; Northrop Grumman Corporation, Electronic Sensors and Systems Division, 18901 Euclid Avenue, Cleveland Ohio 44117-1388; and Raytheon Electronic Systems, Portsmouth Operations, 1847 West Main Road, Portsmouth, RI 02871. Northrop Grumman and Hughes are the qualified manufactures of the MK48 ADCAP Torpedo and its subsystems. Raytheon is a qualified manufacturer of the MK48 ADCAP Sonar Array System. It has therefore been determined that Hughes, Northrop Grumman, and Raytheon possess the required expertise, capabilities, and experience necessary for successful development and implementation of a broadband sonar system in the ADCAP Torpedo.
