USNS HENRY J KAISER - Main Engine Coupling

Military Sealift Command seeks Main Engine Coupling spares for the USNS Henry J. Kaiser (T-AO 187) under Solicitation N3220527Q7038, with quotes due November 20, 2026 at 2:00 PM local time. The Set Aside line reads Total Small Business. The attached justification memorandum records a brand-name, single-source determination for Geislinger Corporation's BC125 Geislinger Coupling, so the solicitation's small business designation and the single-source justification both apply to this procurement. Naval Supply Systems Command (N32205) is issuing the solicitation on behalf of Military Sealift Command.

Place of performance is listed as the United States, with delivery to Military Sealift Command BATS in San Diego, California by December 1, 2026. The RFQ covers 24 line items, including viton o-rings, felt seals, disc springs, lock nuts, snap rings, oil seals, bearings, rotorseal assemblies, torque bar and spring kits, hexhead capscrews, and roll pins. Line items 0004, 0011, 0017, 0018, and 0021 are ship critical safety items subject to heightened quality assurance surveillance and DoD unique item identification under DFARS 252.211-7003. Packaging must follow MIL-STD 2073-1 and MIL-STD 129R, with markings for the USNS Robert F. Kennedy (T-AO 208). The memorandum justifies the brand-name selection to maintain fleet configuration baseline per COMSCINST 4790.3, citing the BC125 coupling on the USNS Joshua Humphreys (T-AO 188), and states the product is a direct replacement part that must be compatible. It also designates the item as critical ship equipment under COMSCINST 4490.1 and SMS Procedure 10.6-002-ALL, and cites FAR 13.106-1(b)(1)(i) under the simplified acquisition threshold. The independent government estimate is redacted.

Pricing is firm fixed-price, with unit prices inclusive of packing and shipping. Written acceptance of the purchase order forms the binding contract, and invoicing runs through Wide Area WorkFlow with specified DoDAAC routing codes.
