UDI Tests ETC Gun from Hybrid-Electric Combat Vehicle

United Defense Industries (UDI, Minneapolis, MN) announced that it successfully fired a 120 mm electrothermal chemical (ETC) gun from a hybrid-electric drive combat vehicle. The effort, using a fully integrated 100 kJ pulse power system, was accomplished through a cooperative research and development agreement with the US Army's Armament Research Development and Engineering Center (ARDEC).

United Defense developed an autoloader that successfully loaded and ejected rounds and stub cases from the vehicle. The fully automatic breech power connection was designed so that electricity reached only the propellant, but not any other part of the cannon or vehicle. Vehicle survivability is also enhanced when using the ETC technology because engagements can be at longer range, and at higher cross-country speeds. The technology has a broad range of applications, including applications to existing and future direct-fire weapons platforms.
