The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the manufacture of spare parts for aircraft, specifically under the title "15--SLAT, AIRCRAFT." This procurement requires firms to provide firm fixed prices for each Contract Line Item Number (CLIN), with evaluation criteria focusing on lead time, price, past performance, and capacity. The parts are critical for maintaining operational readiness and safety in military aviation, and the solicitation is limited to approved manufacturers, necessitating a Source Approval Request for new suppliers. Interested parties must submit their quotes by 2:00 PM EST on the closing date, which is subject to change, and can direct inquiries to Helen Carmelo at Helen.i.carmelo.civ@us.navy.mil or by phone at 215-697-1138.
