The fourth Sea Guardian exercise ran from March 25 to April 1, 2026, in Karachi and off Pakistan's coast, featuring ships, submarines, and aircraft from both navies. It started with a port phase of facility tours, discussions on maritime threats, and a Young Officers Seminar, then shifted to two days of sea drills on air defense, submarine ops, surface warfare, and a joint patrol. Officials noted improved interoperability to tackle regional issues like piracy and trafficking, building on their alliance under the China-Pakistan Economic Corridor.
