About the company
Seager Mechanical Systems LLC, a Subchapter S corporation based in Portsmouth, Virginia, operates as a subcontractor delivering ship repair and outfitting services to federal maritime programs. The vendor has no prime contract footprint and no SBA set-aside certifications; all recent award activity consists of subcontract positions under federal contractors on vessel maintenance and modification work.
Seager's customer base spans two agencies split evenly across recent awards: the Department of Transportation Maritime Administration and the Department of the Navy Secretary of the Navy, each accounting for two awards. All work routes through a single parent vehicle — Indefinite Delivery Contract 693JF721D000007 — under which Seager has delivered four task orders since late October 2025. Work is concentrated in ship building and repairing (NAICS code implied by all four awards). Representative subcontract scope includes toilet flush valve replacements and refrigerator outfitting on a Navy vessel, as well as forklift-equipment sourcing for the same platform, all issued through Crowley Government Services, Inc. as the prime contractor.
Activity is nascent: all four awards in the source date to October 2025, with $516 thousand in combined dollars obligated. The Service Contract Inventory dataset shows no SCI-reportable federal service contracts above the $150,000 threshold, indicating Seager's work is goods-centric or classified below the SCI reporting floor. The vendor appears to operate as a feeder subcontractor to Crowley on maritime repair-and-outfit scope, with no indication of other prime relationships or broader federal customer diversification in the available data.
