This is a Sources Sought Synopsis for market research to identify potential manufacturers and suppliers of specific spare missile parts for the Improved Bradley Acquisition Subsystem (IBAS). The work is to add items to an existing 9-year contract in support of the U.S. Army. The government is seeking qualified sources, including various small business types, but notes this acquisition is currently limited to a small number of responsible sources under specific regulations. Firms capable of producing the listed items are encouraged to identify themselves and seek source approval to compete for future solicitations.
