Lockheed Martin has conducted two successful test flights of the joint air-to-surface stand-off missile – extended range (JASSM-ER) at White Sands Missile Range, New Mexico, US.

During the test, the live 2,000lb-class missiles, released from B-1B bombers, effectively navigated and destroyed their intended targets.

The primary objective of the flight test was to demonstrate end-to-end system performance while exercising the missile’s alternate terminal engagement profile and time-on-target (TOT) mode.

During the TOT, the JASSM-ER adjusted its cruising speed throughout the flight profile based on winds and other atmospheric data.

The first JASSM-ER missile was released from an altitude of 13,000ft at a speed of Mach 0.72, while the second missile was released from 30,000ft at Mach 0.88.

JASSM-ER is an autonomous, air-to-ground, precision-guided stand-off missile designed to meet the needs of US warfighters.

The missile is equipped with a dual-mode penetrator, blast fragmentation warhead, advanced infrared seeker and enhanced digital anti-jam global positioning system receiver.
