What they buy
NAVSUP Weapon Systems Support manages the Navy-unique spare parts that DLA does not carry. The Philadelphia site handles aviation: airframe components, engine parts, avionics, and support equipment for Navy and Marine Corps aircraft. The Mechanicsburg site handles maritime: hull, mechanical, electrical, and combat system parts for ships and submarines.
It buys both new spares and repair of repairable items, so a solicitation may ask you to make a part or to overhaul and test one. Everything is tied to a National Stock Number and usually to a drawing owned by NAVAIR or NAVSEA.
How they buy
Solicitations post on SAM.gov. Small buys often appear as requests for quotation with a short response window and are awarded as purchase orders. Items with steady demand go on long-term contracts, and some whole systems sit under performance based logistics arrangements with the original manufacturer.
Approved source lists matter here more than almost anywhere. A notice will often say the item is procurable only from named manufacturers, or that alternate offers need engineering approval. Set-asides are used where the technical data is available and more than one source exists.
How a small shop gets in
Register in SAM.gov and set alerts for NAVSUP WSS as the contracting office. Look for notices where the data is available and no approved source is named, and quote those first.
For source-controlled items, prepare a source approval request. The package typically covers your quality system, similar parts you have made, and evidence you can meet the drawing, and it goes to the cognizant engineering activity for review. Once approved, you can quote future buys of that NSN. The NAVSUP small business office runs outreach and can explain which commodities are open to new sources.
Approval outlasts any single award
A source approval request takes months of paperwork, but it applies to the NSN, not the solicitation. Pick parts with repeat demand before you invest in one.
