Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent and/or closely related prior contract activity for B-2 heat exchanger remanufacture. Prior awards under FA811824D0019 list Aerocorex as the awardee for multiple periods and values (e.g., $2,079,344; $891,958), with work described as remanufacturing B-2 heat exchangers (including sink and load heat exchangers) at Tinker AFB, along with associated quality, inspection, tooling/test equipment, parts control, and technical order maintenance. The current requirement for purchase of B-2 heat exchanger spares (3 units) is consistent with a continuation of supplying the same type of component used in the B-2 environmental/air conditioning system.
