Accelleron US Inc.

Accelleron US Inc., a foreign-owned manufacturer of marine propulsion components, supplies turbosuperchargers, turbine rotors, rotary pumps, and related turbocharger parts to the U.S. Navy as a prime contractor (96% of recent awards) competing on an unrestricted, full-and-open basis with no set-aside designations. The company operates manufacturing facilities in Somerset, Franklin Township, New Jersey and Cary, North Carolina, delivering specialized components that support naval vessel maintenance, fleet replenishment oiler operations, and maritime logistics.

Accelleron's customer base is narrowly concentrated within the Department of the Navy. Naval Supply Systems Command accounts for 17 awards totaling $5.4 million in combined potential value, while the Navy's Military Sealift Command holds 4 awards carrying $6.1 million combined potential value — together representing the full $11.4 million of obligated dollars across Accelleron's federal footprint. The U.S. Coast Guard placed a single $27 thousand purchase order in August 2026 for ten exhaust mufflers. Naval Sea Systems Command appears in the award record without a disclosed dollar value. The two rankings by award count and potential value are nearly identical, reflecting steady per-order magnitude across both Navy customer streams.

Activity peaked in 2023 with ten awards, followed by a marked decline to three awards per year in 2024, 2025, and 2026. Only one award faces ultimate completion inside the next twenty-four months, with a combined potential value of $240 thousand — a minimal recompete cliff. Accelleron's recent work includes a $5.9 million Military Sealift Command sole-source award in August 2023 for complete turbosupercharger overhaul and certification of multiple fleet replenishment oilers (USNS Kanawha, Ericsson, Patuxent); a $1.99 million Naval Supply Systems Command order in June 2023 for turbosuperchargers supporting vessel maintenance; and a $419 thousand Naval Supply Systems Command purchase order in October 2025 for turbine rotor components. Most awards are firm fixed-price purchase orders with completion dates ranging from three to nine months from award date.

Accelleron subcontracts minimally; a single sub-award to National Steel and Shipbuilding Company for USS Harpers Ferry restricted availability repair work was recorded in December 2025. The company's product portfolio centers on turbosupercharger and components (9 awards), power and hand pumps (5 awards), and gas turbine engine parts (3 awards), per PSC classification — a specialized supplier footprint aligned to naval propulsion-system sustainment and ship overhaul cycles.
