A -- advanced Inertial Reference Unit (Adv-IRU) prototype

an advanced Inertial Reference Unit (Adv-IRU) prototype to support the operation of future airborne and tactical systems. In addition, offerors must show an upgrade path or design variant of their approach to support future space-based electro-optical systems. This effort will be divided into a basic contract with two options. The basic contract will be a 10-month effort (9-month Technical Effort) to develop the preliminary design for the system and the critical design for all long lead hardware items (with vendor quotes). The contractor will also deliver a final report. The first option will be a 13-month effort (12-month Technical Effort) to procure government-approved long lead hardware items identified in the Basic Contract and to develop the critical design for the airborne prototype and the design variant for space-based applications. The second option will be a 16-month effort (15-month Technical Effort) to fabricate/procure, assemble, test and deliver the prototype advanced IRU.
