Dillon Aero
Dillon Aero is a U.S. defense manufacturer and weapons-integration company in Phoenix, Arizona, centered on externally powered Gatling-gun systems, mounts, ammunition handling, training, and lifecycle support for air, land, and sea applications.
2 weaponsDillon Aero's public product line is built around the M134D and M134D-H 7.62 x 51 mm NATO Minigun family, the newer 503D .50-caliber Gatling gun, and the supporting hardware needed to install those systems on aircraft, ground vehicles, naval craft, remote weapon stations, and fixed positions. The company says its systems are fielded internationally and its official brochure describes long-running U.S. government contract activity, USSOCOM program-of-record status for the M134D family, and total-package support that includes hardware, installation, training, spares, and lifecycle support.
The manufacturer also sells the surrounding integration ecosystem: crew-served and fixed-forward mounts, high-capacity ammunition magazines, feed chutes, power supplies, batteries, training courses, range access, and product-support services. Its Phoenix quality certificate describes the business as designing, developing, manufacturing, and supporting the Dillon Aero M134 Gatling gun and related products, which matches the catalog's emphasis on weapon systems rather than small-arms accessories alone.
