What Milpower Source does
Milpower Source is a privately held US defense electronics firm founded in 1984 and headquartered in Belmont, New Hampshire, that designs and manufactures rugged, MIL-SPEC compliant power conversion, power management, networking, VPX, and thermal management subsystems for military and aerospace platforms. Its product portfolio spans DC-DC, AC-DC, and DC-AC power supplies, VITA 62/SOSA-aligned 3U and 6U VPX modules, holdup units, uninterruptible power supplies, ground control unit supplies, airborne power distribution units (e.g., the M9538 8-channel 100A PDU), rugged Ethernet switches and routers under the MILTECH sub-brand (e.g., MILTECH 9116 10G managed switch/router), TSN and dual-enclave cross-domain networking modules, and liquid and forced-convection thermal management hardware. Core technology centers on military-grade power conversion and networking with embedded system management (IPMI 46.11), engineered to meet MIL-STD-1275, MIL-STD-704, MIL-STD-810, and MIL-STD-461 requirements across airborne, ground, naval, and soldier applications. The firm is AS9100D and ISO 9001:2015 certified (valid 2025-2028) and reports over 40 years of field-proven performance across more than 200 defense customers.
The company operates a custom, quote-based enterprise sales model targeting US military branches (Air Force, Navy, Army, Marines, Coast Guard) and a deep bench of defense prime contractors including Lockheed Martin, Raytheon, Northrop Grumman, General Dynamics, Boeing, BAE Systems, L3Harris, Leonardo DRS, Collins Aerospace, Sierra Nevada Corporation, Honeywell, and Elbit Systems. End platforms span avionics, UAVs, C4ISR, electronic warfare, ground vehicles, radar arrays, missiles, surface ships, and submarines, with named program exposure including the F-15/F-16, V-22 Osprey, PATRIOT AN/MPQ-65, NASAMS, AWACS, JSTARS, MESA radar, Trophy APS, and JLENS. Revenue is generated through hardware sales of standard and modified off-the-shelf products, supplemented by custom design engineering services; pricing is non-public and quote-based with multi-year program contracts. Go-to-market is direct enterprise field sales via website quote requests, US and European (Switzerland) sales teams, and a small catalog of technical content channels, with no third-party resellers or marketplace presence.
