The U.S. Government is seeking sources for the procurement of a Switch Assembly (NSN: 5930-01-527-8778, P/N: 79763893-009) for the AH-64 Apache. The estimated quantity ranges from 10 to 50 units. The contractor must provide all necessary services, facilities, labor, parts, materials, equipment, tools, and data. The government does not own the Technical Data Package (TDP), which is held by Lockheed Martin; respondents must demonstrate access to the TDP or explain how requirements can be met without it. The anticipated contract is a Firm Fixed Price Indefinite Delivery Indefinite Quantity (IDIQ) with a 60-month period of performance.
