The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure a sole source item identified as "Shaft, Shouldered" with part number 06371-05802-103. The procurement involves a quantity of one unit, and it is noted that there are no available drawings or data for this item, which limits the ability to source it from multiple suppliers. This component is critical for miscellaneous power transmission equipment, and the government intends to negotiate exclusively with Sikorsky, as they are the only responsible source capable of fulfilling the requirement. Interested parties have 45 days from the notice to submit capability statements or proposals for consideration, and all inquiries should be directed to Kate N. Schalck at kate.n.schalck.civ@us.navy.mil.
