双 V 型车体“斯特赖克”装甲车取代了原有的平底设计，这是因为在伊拉克和阿富汗的简易爆炸装置（IED）袭击中暴露出其生存能力的重大缺陷——其 V 形车底能将爆炸能量向外偏转，而非将其导入乘员舱。该重新设计在不到两年内完成并投入实战部署，成为美国陆军历史上最迅速的重大车辆改装之一。 来源：Military Mechanics 翻译：Qwen 3.5 Plus The Double-V Hull Stryker replaced the flat-bottomed original after IED attacks in Iraq and Afghanistan exposed a critical survivability gap — its V-shaped underbelly deflects blast energy outward rather than channeling it into the crew compartment. The redesign was completed and fielded in under two years, representing one of the fastest major vehicle modifications in U.S. Army history.
