Joint Common Missile Fits into AH-64D Apache Longbow

Released on Tuesday, September 06, 2005

Lockheed Martin has successfully integrated and flown the Joint Common Missile instrumented measurement vehicles (IMVs) on the Boeing AH-64D Apache Longbow attack helicopter, validating the physical and environmental interface between the missile, the M299 missile launcher and the helicopter platform.

The IMV is outfitted with sensors and instrumentation to record the environments the missile must operate under during flights. It contains an inert warhead and rocket motor to simulate a tactical round in flight.

Successful integration of the JCM IMVs, the combat-proven all-digital M299 launcher, and the AH-64D, characterized the vibration, shock, pressure (acoustic) and temperature environments that JCM will experience, and proved the airworthiness of the JCM.

The environmental flights on the Apache are the first in a series of such integration and flight tests that will integrate JCM on the four required platforms for the US Army, Navy and Marine Corps. The remaining collection of environmental data on the Marines' AH-1Z Super Cobra attack helicopter, the Navy's MH-60R/S Seahawk armed reconnaissance helicopter and the Navy's F/A-18E/F Super Hornet jet fighter will be conducted during the remainder of 2005.

Lockheed Martin also supplies the M299 launcher to the Army for the Apache, which has carried and fired HELLFIRE II and Longbow HELLFIRE missiles in Iraq. JCM's aerodynamics are similar to those of HELLFIRE on Apache. Marvin Engineering of Inglewood, California, provides the M299 hardware; the software is produced by Lockheed Martin at its facility in Ocala, Florida.

The other two rotary-wing platforms, the Super Cobra and the Seahawk, will carry JCM on the M59 launcher, which is a minor modification to the M299, and is produced by Lockheed Martin and Marvin Engineering.

The JCM launcher on the Super Hornet will be the LAU-145/A dual-rail launcher, supplied by EDO Corporation of North Amityville, New York. The launcher and JCM models have been fit-checked and uploaded to the aircraft, and successful wind tunnel tests have been conducted. The LAU-145/A includes a pneumatic cooling system to provide JCM sensor cooling for the fixed-wing aircraft, and takes advantage of the existing J-Weapon interfaces on the Hornet.

The only weapon designed to meet eight validated critical capability gaps for the Army, Navy and Marine Corps, JCM provides fixed- and rotary-wing pilots with a precision-strike, adverse-weather, weapon that can defeat a wide range of stationary and moving targets with minimal collateral damage a capability that doesn't exist today.

JCM is the next-generation, multi-purpose, air-to-ground precision missile that will replace the HELLFIRE, Longbow and Maverick air-to-ground missiles currently in the arsenal of the US Army and Navy. To deliver the multi-purpose warhead to its target, the Lockheed Martin JCM includes a tri-mode seeker with imaging infrared, semi-active laser and millimeter wave radar capabilities for active and passive 'fire-and-forget' and precision-strike targeting.
