炮弹在五号州际公路上空爆炸，发生于海军陆战队周年庆活动期间
摘要
一枚实弹炮弹在海军陆战队演示期间提前在五号州际公路上空爆炸，导致高速公路关闭并引发关于公共安全的政治争论。
2025年10月18日，在彭德尔顿营地举行的美国海军陆战队250周年纪念实弹射击演示中，一枚155毫米炮弹在五号州际公路上空提前爆炸。爆炸产生的弹片击中了加州公路巡警（CHP）的一辆警车和副总统JD·范斯安全护卫队中的一辆摩托车。事件未造成人员伤亡，但促使演习被取消，并对现场进行了额外弹片的清理。
在活动期间，CHP关闭了从海洋赛德的港湾大道到圣奥诺弗雷附近巴西隆路的17英里五号州际公路路段，理由是安全考虑。这一临时关闭导致了严重的交通拥堵。
加州州长加文·纽瑟姆批评联邦政府决定在繁忙高速公路上方进行实弹演习，称“在繁忙的高速公路上空发射实弹不仅错误，而且危险。”
海军陆战队官员坚持认为此次演习安全且常规，声称没有必要中断五号州际公路的交通。
目前，针对炮弹提前爆炸的原因正在进行调查，以确定原因并防止未来发生类似事件。
