The anticipated DO is for efforts associated with LRASM integration on the B-52 aircraft platform, to include missile software updates, associated testing, test asset repair, and failure review boards. This contract is being pursued on a sole source basis under the statutory authority of 10 U.S.C. 2304 (c)(1) as implemented by Federal Acquisition Regulation (FAR) Subpart 6.302-1, only one responsible source and no other services will satisfy agency requirements. All responsible sources may submit a capability statement, proposal, or quotation, which shall be considered by the agency. Unless stated herein, no additional information is available. Requests for the same will be disregarded. A determination by the Government not to compete this effort is solely within the discretion of the Government. Lockheed Martin is the sole designer, developer, manufacturer, and integrator of the Long-Range Anti-Ship Missile (LRASM). LMMFC alone has the requisite knowledge, experience, and technical data that can meet the Government's requirements within the required timeframe. Accordingly, LMMFC is the only known, qualified, responsible source that can fulfill the requirements specified herein.
