Two JASSM - ER systems pass successful test
The missile tests, conducted recently at the White Sands Missile Range, in New Mexico, have increased the JASSM-ER programme’s success rate to 91 percent in 11 flight tests, Lockheed, the missile’s manufacturer, said.
During the test, the live 2000-pound missiles were fired from on board the USAF’s B-1B bombers and effectively navigated to and destroyed their intended targets.
While the first JASSM-ER missile was released from an altitude of 13,000 feet and a speed of 0.72 Mach, the second missile was released from 30,000 feet at 0.88 Mach, the company said.
The primary objectives of the tests were to demonstrate end-to-end system performance while exercising the missile’s alternate terminal engagement profile and Time-on-Target (TOT) mode – the ability to control time of flight to engage time critical targets.
During the TOT first-time event for JASSM-ER, the missile adjusted its cruising speed throughout the flight profile based on winds and other atmospheric data.
Lockheed now expects to receive a contract by January 2011from the US Air Force to produce 30 JASSM-ER missiles.
The Initial Operational Test & Evaluation phase, comprising 16 flights, would commence in the second quarter of 2011, with production missile deliveries beginning in late 2012, it said.
The JASSM-ER is an upgraded version of the original JASSM system.
The JASSM is an autonomous, long-range, conventional, air-to-ground, precision standoff cruise missile. It is designed to destroy high-value, well-defended, fixed and relocatable targets. The weapon uses a state-of-the-art infrared seeker and anti-jam GPS to focus on its target.
The JASSM flies at subsonic speed and carries 450 kg penetrator/blast fragmentation warhead. It has been test launched from numerous platforms including the B-1, B-2 and F-16 aircraft. Its future platforms include F-15E, F/A-18 and F-35 fighter aircraft.
The JASSM-ER is more than two-and-a-half times the range of its predecessor.
The US Air Force plans to acquire 4,900 JASSMs and its longer range JASSM-ER.
