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.

A German defense startup demonstrated a 39-foot unmanned surface vessel during a NATO exercise off Portugal, launching attack drones from a boat designed to carry ten of them plus four anti-ship missiles. A smaller 20-foot sister vessel, already operated by the German military, is unarmed. The demonstration highlights how quickly European startups are fielding drone boats for navies as NATO tests new unmanned warfare capabilities.

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.
