Milpower Source, Inc.

Milpower Source, Inc., a foreign-owned manufacturer headquartered in Belmont, New Hampshire, supplies precision-engineered power supplies, converters, and specialized electronic components to the Department of Defense and the Navy as both a prime contractor (64% of recent awards) and a subcontractor to major defense primes. The vendor competes full-and-open — no set-aside designations appear across its federal footprint — and wins work on technical merit and original-equipment-manufacturer status rather than small business preferences.

Milpower Source's capability portfolio centers on AC-DC power supplies, DC-DC converters, uninterruptible power supplies, and related components for complex military platforms. Representative prime work includes a $125,780 firm fixed-price purchase order from Naval Sea Systems Command in February 2026 for MILPOWER USB components, a $134,260 sole-source upgrade of 22 media converters to Naval Sea Systems Command in December 2023, and a $34,353 power unit for Naval Supply Systems Command in July 2023. The vendor also performs verification testing and component-level engineering, exemplified by a $21,000 Naval Strategic Systems Programs order for M357-3 verification tests awarded in January 2025. As a subcontractor, Milpower Source supplies AC-DC and DC-DC power supplies, uninterruptible power supplies, and Ethernet switches to Raytheon (across Patriot weapon system spares, the Advanced Technology Support Program, and KSA FMS production), L3 Technologies (for manned-unmanned teaming, AN/SRQ-4 radio terminal sets, and SPEIR E&MD), General Dynamics Mission Systems (for MK 54 MOD 1 lightweight torpedo sonar assembly), and Serco (for CANES submarine production and afloat networks).

Customer concentration is heavily weighted to the Navy. The top five customers account for 77% of recent awards by count, led by Navy Information Warfare Systems Command (47 awards, $217 thousand combined potential value) and Navy Naval Sea Systems Command (39 awards, $342 thousand combined potential value), followed by Navy Naval Supply Systems Command (25 awards, $424 thousand combined potential value), Navy command-wide (26 awards), and Army PEO Missiles and Space (13 awards). The dollars-by-customer ranking surface Air Force Materiel Command's Air Force Sustainment Center ($502 thousand across 3 awards) as the single highest-value customer, reflecting C-130J support work for the Coast Guard and power-supply requirements for Air Force platforms; however, the Navy dominates the active customer base and accounts for most of the award volume. Milpower Source has served 28 distinct customer agencies across its portfolio.

The vendor places task orders under five named indefinite-delivery contracts: IDC N6600121D0153 (6 task orders), IDC SPRBL115D0017 (5 task orders), IDC W58RGZ24D0065 (5 task orders), Consolidated Afloat Networks and Enterprise Services Full Deployment Production (5 task orders), and Advanced Technology Support Program IV (3 task orders). The vendor's primary NAICS footprint aligns with power manufacturing: Power, Distribution, and Specialty Transformer Manufacturing (59 awards) dominates, followed by Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (14 awards), and Engineering Services (11 awards). Top PSC categories include Converters, Electrical, Nonrotating (38 awards) and Maintenance, Repair, and Rebuild of Electric Power Distribution Equipment (14 awards), reflecting the vendor's core business.

Activity has accelerated sharply: one award in 2021, seven in 2023, eighteen in 2024, and forty-five in 2025, with seven additional awards in 2026. The combined potential value across all 196 awards totals $1.7 million; however, obligated dollars stand at $17.6 million, indicating that the vendor has invoiced significantly against its awarded contracts — a signal of execution maturity and sustained customer trust despite the small nominal contract ceiling values. The vendor's export footprint includes international foreign military sales work for Switzerland and Romania routed through Raytheon sub-awards, placing Milpower Source in the supply chain for allied defense platforms as well as U.S. Navy systems.
