Program Office intends to solicit and award a sole source contract and/or separate contract(s) under the authority of FAR 6.302-1 to Northrop Grumman Systems Corporation, 7323 Aviation Blvd., Baltimore, MD 21240-2001. This acquisition will be an Indefinite Delivery, Indefinite Quantity (IDIQ) contract, using a combination of Cost Reimbursement and Fixed Price contract types. The Period of Performance is date of contract award to 31 Dec 2026 and will cover eight (8) additional option ordering periods (estimated: Award - 31 Dec 2034). Northrop Grumman is the current developer for the Stand-in Attack Weapon (SiAW) weapon system and is the only known company that has detailed knowledge necessary to provide the required SiAW Active Seeker specific support. Northrop Grumman possesses the necessary access to the weapon technical data, as they are the Original Equipment Manufacturer (OEM). Selection of any other vendor would result in a substantial duplication of effort to develop similar technical data, comprising the development of SiAW as well as an unacceptable delay in fulfilling the agency’s requirements.

The scope of this IDIQ contract will provide resources including, but not limited to, further development and integration of the SiAW Active Seeker an all associated components, Test and Evaluation Support, Science and Technology development, and Integration and Assembly.
