Rubb, Inc.

Rubb, Inc., doing business as Rubb Building Systems, manufactures and delivers fabric-covered, tension membrane structures — including aircraft shelters, storage buildings, and specialty tents — to the Department of Defense and allied military customers as a prime contractor (98% of awards). The Maine-based company is self-certified as a small disadvantaged business and competes predominantly in full-and-open federal procurement, with occasional small-business set-asides; recent awards span purchase orders and definitive contracts ranging from $5,600 to $176,000 in ceiling value.

Rubb's customer base concentrates heavily within the defense industrial base. The top five customer agencies account for 60% of recent awards by count but only 17% by combined potential value, signaling a high-volume, modest-dollar profile typical of goods manufacturing. The Department of the Air Force (20 awards, $176 thousand combined potential value) and the Department of the Navy (16 awards at Naval Sea Systems Command and fleet level, combined $962 thousand potential value) dominate the award count. Naval Sea Systems Command anchors the largest single-customer bucket by dollars, followed by the Army Corps of Engineers' Charleston District (one $487 thousand award for a storage facility) and Air Forces Europe (two awards totaling $277 thousand for a munitions storage building at Buchel Air Base, Germany). The Air National Guard has placed six awards ($215 thousand combined potential value) for aircraft shelter inspections and fabric structure repairs. Rubb's work spans domestic bases (Texas, Washington, Maine) and overseas locations (Germany, Japan).

Rubb sits on five GSA Federal Supply Schedules — GS07F0375J (12 task orders, $185 thousand combined potential value), GS00F0803F (7 task orders), GS08F37470 (3 task orders), GS00F0018F (2 task orders) — and holds an Indefinite Delivery Contract with the Defense Logistics Agency (DAKF4088C0766). Representative prime contracts include a $176,125 Air Force building upgrade (September 2025, Sanford, Maine), a $120,670 Naval Sea Systems Command purchase order for propeller tents (July 2022), a $144,615 Air Forces Europe purchase order for a munitions storage building extension at Buchel AB, Germany (June 2023), and multiple Air National Guard inspection and repair contracts ($18,000–$20,000 range, 2024–2026). In 2025, Rubb received a $128,500 Project Grant from the U.S. Department of Agriculture's Rural Business Cooperative Services under the Rural Energy for America Program (CFDA 10.868) to develop renewable energy systems, with completion targeted for April 2027 — a strategic expansion beyond its traditional defense sector focus into sustainable energy infrastructure.

Activity has been episodic: two awards in 2022, two in 2023, one in 2024, six in 2025, and one in 2026 (through early June). The combined potential value across all 94 awards in the source dataset is $13 million, with $10.1 million obligated (77% delivery rate). Recompete exposure in the next twenty-four months is minimal — only two awards ($18 thousand combined potential value) reach ultimate completion inside that window. Rubb's primary NAICS category is Prefabricated Metal Building and Component Manufacturing (42 awards), with secondary exposure in Fabricated Structural Metal Manufacturing (3 awards) and Canvas and Related Product Mills (2 awards). The vendor subcontracts rarely: only 2 sub-awards appear in the source dataset, including a KBR Services fabric structure repair sub-award (August 2025) for base operations support in Japan and a Battelle Memorial Institute sub-award (February 2023) for fabric structures supporting recreation and vehicle storage. Service Contract Inventory reporting shows minimal SCI activity — two records as named subcontractor, 0.3 FTEs in FY2022 and 0.0 FTEs in FY2024 — reflecting Rubb's goods-manufacturing footprint, which falls outside the SCI reporting threshold for product-based contracts.
