NATO navies

Iran's Islamic Revolutionary Guard Corps Navy has captured a second US-made Remus 600 unmanned underwater vehicle in the Strait of Hormuz, according to the report. The incident points to continued friction between Iranian forces and the US Navy over surveillance drones operating in one of the world's most critical oil shipping lanes, and follows an earlier seizure of the same type of equipment.

The Royal Navy frigate HMS Portland has test-fired the Naval Strike Missile and Sea Venom anti-ship missiles during exercises in the North Atlantic, demonstrating the ship's upgraded strike capabilities. The firings showcase the frigate's ability to engage surface targets at range, and come amid heightened NATO naval activity and monitoring of Russian vessels in northern waters.
