The Indian Navy’s indigenous guided missile destroyer INS Imphal took part in a Passage Exercise (PASSEX) with the US Navy’s guided-missile destroyer USS Gridley (DDG 101) in the Arabian Sea on September 29, 2025, an official statement said.

It said that the two warships carried out a series of joint activities, including tactical manoeuvres, cross-deck flying, and anti-piracy VBSS (Visit, Board, Search and Seizure) training. The crews also shared best practices and operational procedures to improve interoperability between the two navies.
