The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting offers for the procurement of aircraft main slings. This solicitation aims to acquire spare parts, with a focus on competitive procedures limited to government-approved sources. The evaluation criteria will prioritize non-price factors such as capacity, delivery, and past performance, with delivery time being the most critical factor in the selection process. Interested vendors must submit proposals that include relevant past performance references from the last three years, and all submissions should be directed to Brian Kent at 215-697-0000 or via email at BRIAN.T.KENT.CIV@US.NAVY.MIL. The contract will be awarded based on the evaluation of both price and non-price factors, with specific attention to the timeliness of delivery.
