2005年1月4日,美国军火巨头洛克希德—马丁公司披露将卖给台湾449枚“海尔法”空对地导弹,总价在5000万美元左右。台军表示,将把“海尔法”导弹用于攻击军舰,这就要求减小穿甲能力,扩大杀伤面积。于是,洛克希德—马丁公司将导弹弹头改为爆炸破片型,以提高对军舰的打击能力。 On January 4, 2005, the U.S. arms giant Lockheed-Martin Company disclosed that it will sell 449 “air-to-air missiles to Taiwan” at a total price of about 50 million U.S. dollars. The Taiwan military said it will use “Hailefa” missiles in assault warships, which requires the reduction of armor penetration capacity and the expansion of the killer area. As a result, Lockheed Martin changed the missile warhead into an explosive fragment in order to enhance the combat capability of the warship.
