The Department of Defense, specifically the Department of the Army, is seeking information regarding potential solutions for an Aircrew Cooling System to address excessive heat issues in the KC-135 aircraft. The primary objective is to gather market research on innovative solutions that can mitigate heat stress for aircrew members, focusing on factors such as mobility, ease of implementation, size requirements, and transportation convenience. This initiative is crucial for maintaining operational effectiveness and safety, as cabin temperatures can exceed 135°F in hot environments. Interested parties are encouraged to submit their responses electronically, with inquiries directed to 1LT Christopher Fisher at christopher.fisher.7@us.af.mil or MSgt Benjamin James at benjamin.james.1@us.af.mil. This notice is not a request for quotes, and no awards will be made from this RFI.
