美国是拥有重型轰炸机最多的国家,目前一共有208架,包括三种机型:B-52、B-1和B-2。美军方计划在2040年前基本保持这种状况,根据美国准备同时打两场局部战争的方针,美空军认为保持130架可用的重型轰炸机是最低需求,为此,飞机数量要在170架以上。而现在实际上“作战可用”的飞机只有1112架,因此,最近几年内还必须采取措施将已专用于训练的一些B-1改回来。而到2037年不生产新飞机仍能保持这种实力的 The United States is the country that owns the largest number of heavy bomber planes and currently has a total of 208 aircraft in three models: B-52, B-1 and B-2. The U.S. military plans to basically maintain this situation by 2040. According to the U.S. plan to fight two localized wars at the same time, the U.S. air force believes it is the minimum demand to maintain 130 usable heavy bomber aircraft and, for this reason, the number of aircraft is above 170. And now, in fact, there are only 1112 “combat-ready” aircraft, so steps must be taken in recent years to bring back some of the B-1s that have been earmarked for training. By 2037, however, it will maintain its strength without producing new aircraft
