ATK Defense is an industry leader in ammunition, precision and strike weapons, missile warning solutions, and tactical rocket motors across air-, sea-, and land-based systems. The group is the largest US producer of small-calibre ammunition, as well as a leading producer of medium- and large-calibre ammunition and medium-calibre chain guns. The group is home to ATK’s Advanced anti-radiation guided missile (AARGM), next-generation GPS-guided mortar and artillery projectiles, joint and allied threat awareness system (JATAS), AAR-47 missile warning system, fuzes and warheads, propulsion and controls for missile defence interceptors, weaponised special mission aircraft and advanced propulsion. Some of its contributions in land systems are:

Small calibre systems

ATK Small Caliber Systems is the world’s leading producer of high-quality military small calibre ammunition and links. During the 11 years ATK has operated the Lake City Army Ammunition Plant in Independence, Missouri, ATK has delivered more than 11 billion rounds of 5.56mm, 7.62mm and .50 calibre ammunition for use by United States and international military services. In partnership with the Army, ATK is successfully executing a $276 million modernisation project at the Lake City plant. This will ensure the plant remains a viable national asset for another 70 years.

Surface-to-surface missiles

Javelin: ATK is under contract to the Javelin joint venture (Lockheed Martin and Raytheon) to supply the composite launch tube assembly for the Javelin missile, the world’s premier shoulder-fired, multi-purpose combat system.

Long-range land attack projectile (LRLAP): ATK produces the rocket motor and tail fin assembly for the Long-Range Land Attack Projectile (LRLAP) for the Advanced Gun System (AGS). The AGS is a 155mm gun system for the US Navy’s new DD(X) surface combatant ships. It will provide flexible, sustainable, and affordable firepower against a wide range of littoral and inland targets as well as for anti-surface warfare.

Precision attack missile: ATK is designing developing, and manufacturing the rocket motors for the Non Line of Sight – Launch System Precision Attack Missile (NLOS-LS PAM) programme under a contract from Raytheon Missile Systems. The US Army will use the PAM primarily against tanks, armoured, lightly-armoured, and other stationary or moving targets. The US Navy plans to integrate the system as a weapon module on the littoral combat ship and unmanned surface vehicle to defeat threats such small moving boats.

Tube-launched, optically-tracked, wire-guided (flight motor): ATK has been the sole source supplier of the TOW flight motor since the early 1980s. The motor uses the proven minimum smoke propellant to propel the missile downrange. The flight motor incorporates dual canted nozzles that vent the exhaust gases at an oblique angle to the missile line of flight to avoid damage to the trailing control wires. In addition to the flight motor, ATK manufactures the TOW launch motor.
