PARIS — United States production of some missiles continues to be constrained by a supply squeeze for rocket motors, Raytheon officials said at the Paris Air Show last week.Raytheon’s naval power unit, which supplies missiles including the SM-2 and SM-6 models as well as the AIM-9X Sidewinder, is still hampered by availability of rocket motors, Barbara Borgonovi, who heads the business, said in a press briefing at the展示。“这不仅涉及当今需求的限制，而且更多的是我们将来看到的需求增加，” Borgonovi说。 “我们必须在我的许多计划中拥有更多的供应来源，以使火箭电机能够达到这一需求。”火箭电机一直是提高美国高级弹药的产量的障碍，最近几十年来，行业巩固了关键组成部分的国内供应商的数量。 Meanwhile, the conflicts in Ukraine and the Middle East have used up thousands of missiles, depleting the stockpiles of the U.S. and its allies.Missile makers and their suppliers have been looking to grow and diversify production in response, expanding existing capacity or adding entire production lines for rocket motors.Raytheon is supporting current suppliers, which for many of the programs overseen by Borgonovi is Aerojet Rocketdyne, owned by L3HARRIS。这位高管表示，Aerojet一直在投资，并且“在2025年取得了良好的开端”，到今年5月，与2024年5月的主要火箭电机提供了许多主要的火箭电机。雷神（Raytheon）的火箭运动策略的第二部分是扩大许多现有成功合作伙伴的业务。美国防空系统总裁Sam Deneke说，该公司依靠挪威的Nammo来支持Amraam空对空导弹和进化的Sea Sparrow导弹或Essm.Rocket Motors为Amraam生产提供“非常健康”的供应链的限制。对于ESSM，Nammo“做一个Incessib
