尽管美国三军的防区外攻击导弹(TSSAM)计划采购量已减到6650枚,但其研制费用已增加到154亿美元。原先海空陆三军计划购买8650枚这种低可观测巡航导弹,总采购费约139亿美元。目前陆军已从1400枚减到600枚,空军仍计划买5000枚,而海军准备买1050枚。 Although the planned purchases by the U.S. Armed Forces for Offensive Area Attack Missiles (TSSAM) have been reduced to 6,650, their development costs have increased to 15.4 billion U.S. dollars. The original Air and Land Third Army plans to purchase 8650 such low observable cruise missiles, the total purchase cost of about 13.9 billion US dollars. The army has now been reduced from 1400 to 600, the Air Force still plans to buy 5000, while the Navy is ready to buy 1050.
