Gyros Unlimited

Gyros Unlimited, operating as North Bay Aviation Division, is a veteran-owned small business based in Fairfield, California that performs aircraft component repair, overhaul, and logistics support services for Department of Defense and Department of Homeland Security customers as both a prime contractor (52% of recent awards) and a subcontractor (48%). The company is a for-profit Subchapter S corporation and competes predominantly full-and-open without set-aside designations on the majority of its prime work, though one Coast Guard indefinite delivery contract carries a Total Small Business set-aside.

North Bay Aviation's prime capability footprint centers on specialized repair and maintenance of military aircraft components—power supplies, altimeter servo controls, flight control computers, electro-mechanical actuators, and related line replaceable units—for legacy platforms including the C-130 Hercules, E-3 AWACS, TH-1H helicopter, and HC-130J. Representative prime work includes a $358,260 delivery order from the Air Force Sustainment Center (March 2026) for C-130/E-3 power supply repair under a $2.46 million indefinite delivery contract running through September 2027; a $156,610 purchase order from Naval Supply Systems Command (April 2024) for servo-controlled altimeter delivery; and a $15,540 delivery order from Air Force Sustainment Center (November 2025) for altimeter servo control repair on TH-1H helicopters. The company also holds a $250,000 Blanket Purchase Agreement with Air Force Materiel Command under the Air Force Repair Enhancement Program, awarded May 2025 through April 2030.

Customer concentration is split between defense logistics and air force sustainment. The Air Force Sustainment Center dominates by potential value—22 awards totaling $5.6 million (75% of combined prime and sub potential value)—while Naval Supply Systems Command places the highest award count at 31 orders ($581 thousand combined value), followed by the Coast Guard with 28 awards ($811 thousand). Army Materiel Command Security Assistance Command and Naval Air Systems Command complete the active set. Prime indefinite delivery contracts anchor North Bay Aviation's Air Force work; the company maintains active IDCs with Air Force Sustainment Center for power supply repair ($2.46 million ceiling through September 2027, and a separate $743,050 contract through March 2030) and for altimeter servo control repair on TH-1H helicopters ($79,950 through March 2027).

On the subcontractor side, North Bay Aviation performs repair work under five primary primes: S&K Aerospace LLC and S&K Federal Services LLC (Army Foreign Military Sales and P-8A aircraft component repair under IDIQ contracts W91CRB19D0028 and W91CRB23D0023, each carrying 14–15 task orders), Vertex Aerospace LLC (E-6B contractor logistics support), S&K Logistics Services LLC (Army security assistance enterprise Foreign Military Sales), and Boeing (C-17 Globemaster III sustainment). Subcontract work mirrors prime capability—flight control computers, power units, stabilizer trim actuators, display units, and gas turbine power units for both active-duty platforms and Foreign Military Sales cases.

Activity has grown sharply—from four awards in 2022 to 42 in 2024—before moderating to 32 in 2025 and 2 year-to-date in 2026. Five awards carrying $540,000 combined potential value face ultimate completion inside the next twenty-four months and present recompete exposure. The company's award portfolio spans 139 total transactions (52% prime, 48% sub) with combined potential value of $7.5 million and $6.3 million obligated. NAICS concentration sits with aircraft parts manufacturing (46 awards) and support services for air transportation (30 awards), with primary PSC codes tracking maintenance and repair of aircraft components and electrical equipment.
