Lockheed Martin has successfully completed the fifth flight test of its modernised tactical missile system (TACMS), which was developed for the US Army.

Conducted at the army's White Sands Missile Range in New Mexico, the test confirmed that the missile functions as designed and is in compliance with performance requirements of the Engineering & Manufacturing Development (EMD) programme.

Lockheed Martin Missiles and Fire Control Precision Fires & Combat Maneuver Systems vice-president Scott Greene said: "The continued success of the modernised TACMS flight test programme validates production readiness.

"Our team is singularly focused on performing for our customer, the US Army, because we know we cannot let them down on the battlefield."

"The continued success of the modernised TACMS flight test programme validates production readiness."

During the test, the long-range tactical surface-to-surface missile was launched from a high mobility artillery rocket system (HIMARS) launcher towards a target that was 85km away.

This missile was equipped with new guidance electronics and the added capability to defeat area targets without leaving behind unexploded ordnance, as part of the US Army's TACMS Service Life Extension Program.

The TACMS modernisation process includes the disassembly and demilitarisation of TACMS Block 1 and 1A submunition warheads, which will be replaced with new unitary warheads to comply with the US Department of Defense's policy on cluster munitions and unintended harm to civilians.

The modernisation process is also said to reset the missile's shelf life.

The TACMS platform facilitates the quick integration of new payloads and capabilities to meet current and future demands.

Lockheed's TACMS missiles can be fired from the entire family of multiple launch rocket system (MLRS) launchers.

To date, more than 580 TACMS have been fired in combat operations and the system has demonstrated extremely high rates of combat accuracy and reliability, Lockheed stated.
