American Turbo Systems Inc.

American Turbo Systems Inc., doing business as American Turbo Systems, is a self-certified small disadvantaged business and manufacturer of aerospace and aviation components based in Tucson, Arizona, that supplies axial impeller fans, gas turbine engines, and related propulsion system components to defense agencies as a prime contractor, competing full-and-open without set-aside designations across a 107-award footprint.

American Turbo Systems is a for-profit manufacturer specializing in turbine and gas turbine engine components, with primary NAICS focus on Turbine and Turbine Generator Set Units Manufacturing (25 awards) and Motor Vehicle Air-Conditioning Manufacturing (20 awards). The company has been registered in SAM.gov since 2001 and has maintained consistent federal contracting activity across more than three decades, though recent award volume is modest — four awards in 2025, two in 2024, and three in 2023 — relative to its historical baseline. The vendor holds no parent GWACs, agency-wide IDIQs, or GSA Schedules; instead, it operates almost exclusively under single-award indefinite delivery contracts with individual defense components, issuing delivery orders and purchase orders for specific components and repair services.

Customer concentration is heavily weighted toward defense sustainment. The Department of the Air Force Materiel Command Air Force Sustainment Center dominates by award count (32 awards, $4.4 million combined potential value), but the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command anchors dollar value (6 awards, $9.8 million combined potential value). Defense Logistics Agency components — Aviation and Land and Maritime — account for 21 awards with $270 thousand combined value. These five customer entities represent 100% of combined potential value across the portfolio. Work is performed at the contractor's facility in Tucson, Arizona.

Representative prime work includes a $528 thousand Army delivery order (August 2021–October 2022) for overhaul of ten gas turbine engines (NSN 2835-01-180-0452); multiple Air Force Sustainment Center delivery orders for axial impeller fans ranging from $8,388 to $33,240 under a $520,101 indefinite delivery contract running through October 2025; and a $9,999 Naval Supply Systems Command purchase order (November 2024) for a gas turbine engine. A new $468,051 single-award indefinite delivery contract with the Air Force Sustainment Center was awarded October 27, 2025, with ultimate completion in October 2030, extending the vendor's Air Force footprint an additional five years. Top parent IDVs include Air Force Sustainment Center contract FA851908D0005 (13 task orders, $880 thousand potential value), Army contract W58RGZ16D0065 (5 task orders, $4 million potential value), and Air Force contract FA851721D0001 (9 task orders, $158 thousand potential value). The vendor operates as a sole prime across all awards — no subcontract or teaming relationships are present in the footprint.

Combined potential value across all 107 awards totals $14.8 million, with $8.5 million obligated to date (58% obligation rate). The vendor competes in full-and-open procurements without leveraging small disadvantaged business set-asides, reflecting competitive positioning as a direct prime supplier to defense depot maintenance and sustainment programs rather than as a targeted set-aside incumbent.
