US Turbine & Accessory LLC

US Turbine & Accessory LLC, a self-certified small disadvantaged business based in Taylor, Michigan, provides aircraft engine maintenance, repair, and overhaul (MRO) services to the Department of the Navy as a prime contractor holding a single-award indefinite delivery contract (IDC) worth $245.95 million. The vendor is an FAA/EASA-certificated repair station specializing in inspection, repair, and testing of General Electric J85 aircraft engines used in the F-5F/N Tiger II Adversary platform, operating on full-and-open competition without set-aside designations.

US Turbine & Accessory LLC holds the NAVAIR Whole Engine Inspection and Repair Services single-award IDC, awarded in June 2023 with a ceiling of $245.95 million and a performance period through December 2032. The Naval Air Warfare Center has issued five task orders against this vehicle to date, including a $4.38 million delivery order for J85 engine inspection, repair, and testing services awarded in April 2026, a $2.98 million January 2026 task order for maintenance and overhaul work, a $3.10 million order from November 2023, and a $3.95 million order from August 2023. A $10,000 contract execution support order completed in May 2024 rounds out the active portfolio. Combined potential value across the five Navy delivery orders totals $14.4 million, with $15 million already obligated across the vendor's entire award footprint. All Navy work is performed at the contractor's Taylor, Michigan facility.

Customer concentration is extreme: the Naval Air Warfare Center accounts for 100% of combined potential value ($260.4 million), representing eight awards across the primary IDC and subordinate task orders. The vendor holds minimal exposure to other agencies — NASA Glenn Research Center and the Defense Logistics Agency Aviation each account for fewer than $70 thousand in combined potential value across two small awards each, reflecting transactional rather than strategic relationships. The top category concentration aligns with the Navy's J85 engine focus: 8 awards fall under Aircraft Engine and Engine Parts Manufacturing (NAICS); the PSC profile is dominated by Maint/Repair/Rebuild Of Equipment–Engines, Turbines, And Components (6 awards).

Activity is heavily concentrated around the June 2023 IDC award and its subsequent task orders. The vendor shows sporadic historical awards (one in 2015, one in 2016) before a four-award cluster in 2023 and two awards in both 2024 and 2026. One award with a $4.38 million potential value reaches ultimate completion within the next twenty-four months, presenting a recompete exposure window for the J85 engine inspection and repair scope. In its subcontractor role, US Turbine & Accessory LLC performs F-5 aircraft maintenance work including turbine assembly and compressor assembly services to Amentum Services, Inc., delivering specialized engine component support under the prime's broader aircraft maintenance programs. The vendor's revenue profile remains heavily dependent on NAVAIR task-order execution against the single master contract, with no diversification across additional agencies, vehicles, or business lines evident in recent award activity.
