Marmon Aerospace & Defense

What Marmon Aerospace & Defense does

Marmon Aerospace & Defense, now operating as Marmon Defense following an April 2026 rebrand, is a Berkshire Hathaway subsidiary that designs and manufactures mission-critical wire and cable interconnect solutions for defense and aerospace applications across Land, Air, Sea, and Space domains. The company's core technology is built around irradiated cross-linked polymer insulation systems — including cross-linked ETFE, polyalkene, polyethylene, and fluoropolymers — that deliver performance characteristics such as low-smoke zero-halogen construction, EMP resistance, seawater tolerance, and operating ranges from -100°C to 538°C. The portfolio spans QPL-listed mil-spec products (M22759, M81044, M27500, M24640, M24643, M16878, M55021), proprietary branded lines (AD1044ZH®, AD50, AD4, Surprenant EMZ®, DEFENSE-Link®, FG2000®, Surprenant Lo-Flo, 19050 space cables), and custom cable manufacturing. Sub-brands Harbour Industries, Marine Tech, TE Wire & Cable, KITCO Fiber Optics, CCPI Europe, and RSCC are retained under the Marmon Aerospace & Defense Group umbrella.

The business operates on a sales-led B2B enterprise model, selling direct to US military branches (notably the US Navy), defense prime contractors, and aerospace OEMs while also reaching standard mil-spec volume through an authorized distributor network. Pricing is quote-based with multi-year contract cadence; pricing points are not publicly disclosed. The company operates four US manufacturing facilities totaling over 170,000 square feet (Manchester, NH; Hooksett, NH; Naples, FL; York, PA), and is one of 12 business units consolidated under Marmon Engineered Wire & Cable. Customer concentration is centered on US Navy and naval defense applications, with NAVSEA-approved DEFENSE-Link® communications cables and circuit integrity products acquired through the February 2025 Marine Tech Wire & Cable deal being especially relevant to naval fleet upgrade programs. The company holds NAVSEA, MIL-SPEC, SAE, NEMA, UL, NASA SP-R-002, and QPL certifications that create high regulatory switching costs for its defense customer base.
