A B-1 bomber loaded with GBU-54 Laser Joint Direct Attack Munitions takes off during the Combat Hammer exercise at Ellsworth Air Force Base, S.D., Feb. 19, 2014. B-1 aircrews from the 34th Bomb Squadron employed GBU-54 LJDAMS against moving targets during the Air Force’s air to ground Weapon System Evaluation Program known as Combat Hammer, Feb. 18 to 20, which allows maintenance, munitions, weapons and aircrew Airmen the opportunity to train with these weapons.
