The announcement was made on behalf of the Javelin Joint Venture, the Lockheed Martin and RTX partnership that produces the Javelin weapon system. Kongsberg Defence & Aerospace manufactures the MCT turret used in the demonstration.
The MCT-30 is an unmanned turret developed for the U.S. Marine Corps Amphibious Combat Vehicle program and serves as the main armament of the ACV-30 variant. Derived from Kongsberg’s RT-20 design, it can carry a Northrop Grumman Bushmaster II family cannon in either 30 mm or 40 mm configuration.
The turret can hold up to 150 cannon rounds and carries a coaxial 7.62 mm machine gun with 200 rounds. Its modular design can also accommodate an anti-tank missile launcher, two to four launchers for 70 mm laser-guided APKWS munitions or a roof-mounted remote weapon station.
Javelin is taking a step toward greater integration on the battlefield.

The configuration tested in Norway used a twin Javelin launcher that retracts during transport and rises above the turret roof for firing. Its housing is fitted into the rear-right section of the turret bustle and covered by light metal shielding.
The enclosed arrangement appears to offer greater protection from changing weather conditions than conventional external launchers, although its ballistic protection may be limited to the lightest projectiles and fragments. The design may also make launcher replacement or reloading more difficult following a malfunction or combat damage.
