UK and US test-fire torpedo from unmanned underwater vehicle for first time

The United Kingdom and the United States have test-fired a torpedo from an unmanned underwater vehicle for the first time. The test took place in British waters last week as part of the AUKUS defense pact with Australia. The British government announced the milestone on Monday, highlighting it as a significant advance for future submarine technology and NATO's underwater capabilities. The torpedo was launched from a 12-meter-long British-made drone named Excalibur. This development reflects Western efforts to modernize military forces with autonomous systems in response to threats from Russia and Iran.
