US, UK Launch Torpedo From Robot Sub

The US Navy and Royal Navy launched a 3,700-pound Mk 48 torpedo from the uncrewed submarine XV Excalibur on September 13 at Scotland's BUTEC range, a first for allied undersea warfare. The test validated weapon interchangeability under AUKUS Pillar 2 and leads to Project CUTLASS with Anduril's Dive-XL.
