About Stewart & Stevenson Fdda LLC
Stewart & Stevenson Fdda LLC, operating as Florida Detroit Diesel-Allison, is a Fort Lauderdale, Florida-based limited-liability company that supplies diesel engine components, overhauls, and maintenance services to the U.S. Coast Guard and Defense Logistics Agency as a prime contractor on full-and-open purchase orders and indefinite delivery contracts. The vendor is a child entity of Stewart & Stevenson Power Products LLC, a Houston-based manufacturer and distributor of power solutions.
Florida Detroit-Allison operates entirely as a prime contractor (100% of recent awards) across a high-volume, low-dollar transaction portfolio. The vendor competes without set-aside designation in most circumstances, though select awards carry Total Small Business set-aside status. The company is an authorized distributor for Rolls-Royce Solutions, MTU, Allison Transmissions, Detroit, and Mercedes diesel power systems.
The customer concentration is extreme and Coast Guard-focused. The Department of Homeland Security's U.S. Coast Guard accounts for 553 awards (47% of all awards) with $78.1 million in combined potential value—a dominant share that reflects the vendor's role as a critical supplier for Coast Guard maritime diesel propulsion and auxiliary engine systems. Defense Logistics Agency Land and Maritime places the second-highest volume (391 awards, $8.5 million), followed by DLA Aviation (94 awards, $3.1 million) and the Department of the Army Materiel Command (25 awards, $7 million). Together, these five customer lines cover 89% of combined potential value. The awards are heavily transactional: median individual purchase-order values range from under $5,000 to roughly $190,000, with the notable exception of an $8 million indefinite delivery vehicle for MTU engine overhauls on 154-foot Fast Response Cutters (awarded May 2022, completion May 2025).
The vendor's parent IDVs include Coast Guard contract HSCG4011D11005 (274 task orders, $16.5 million combined potential value), HSCG8013DPFR821 (69 task orders, $6.8 million), and DLA contract 70Z08019D13001B00 (64 task orders, $6.1 million). Representative awards span cylinder-head overhauls and inspections ($191,263 for 60 Rolls-Royce diesel heads for Medium Endurance vessels; $64,758 for Rolls-Royce fuel injection nozzle overhaul), MTU component procurement ($275,036.75 for Rolls-Royce parts for small boats as a Total Small Business set-aside; $111,534 for MTU marine diesel parts as a Total Small Business set-aside), hydraulic and transmission components ($19,448 for fuel cam actuated pumps for MTU 8V4000 engines), and routine maintenance ($22,481 for a Rolls-Royce local operating station).
Activity has remained flat at roughly three to four awards per year across 2022–2025, with two awards recorded as of March 2026. The combined potential value across all 1,171 awards totals $109.4 million, with $50.1 million obligated (46% draw-down), reflecting heavy utilization against the standing IDVs. The Service Contract Inventory dataset reports only four SCI records (all as named subcontractor roles in FY2024, totaling 3.3 FTEs), indicating the vendor's purchase-order and parts-supply activity falls below the $150,000 SCI reporting threshold in most instances and operates outside the federal services-contract reporting framework. The vendor has no subcontractor footprint in the award data and does not operate as a sub to other primes in this federal portfolio.
