在1991年举世瞩目的海湾战争中,面对能在40公里距离进行交战的伊拉克炮兵,美陆军炮兵武器明显地暴露出在射程上不占优势。为此,美陆军正在对M270式多管火箭炮弹药进行一系列改进,以便增大读武器的射程,提高它的精度,降低其成本,并使火箭弹能够运载新的战斗部。美陆军对多管火箭炮弹药的改进主要包含两个方面:其一是提高火箭炮弹药的射程,美陆军于1992年投资约2300万美元发展增程型火箭炮弹药,这种增程型弹药
In the 1991 Gulf war that took world-wide attention, the U.S. Army artillery arms obviously showed no superiority in range, in the face of Iraqi artillery capable of engaging at a distance of 40 kilometers. To this end, the U.S. Army is making a series of improvements to the M270 multi-barrel rocket ammunition in order to increase the read range of its weapons, increase its precision, reduce its cost and enable the rockets to carry new warheads. The improvements made by the U.S. Army to the multi-barrel rocket and ammunition mainly include two aspects. One is to increase the range of the rocket and ammunition. The U.S. Army invested about 23 million U.S. dollars in 1992 to develop extended-range rocket ammunition.
