The Malabar naval exercise commenced on November 10, hosted by the US at its Guam military base, involving the navies of India, the US, Japan, and Australia. The nine-day event features a harbour phase focused on operational planning and communication alignment, followed by a sea phase with naval drills emphasizing joint fleet operations, anti-submarine warfare, and aerial maneuvers. The exercise is particularly significant as all four countries utilize the same maritime surveillance platforms, enhancing interoperability and real-time coordination in maritime security. This collaboration underscores the commitment of the Quad nations to strengthen regional stability and counterbalance emerging threats in the Indo-Pacific region.
