On 4 November 2026 India's home-built frigate INS Sahyadri tied up at Yokosuka, Japan, for Exercise Malabar 2026 with the United States, Japan and Australia. What the official releases confirm about harbour and sea work, and what they still leave blank._ Published 5 November 2026 by the AllIndia.news defence desk. Section: Defence, Exercises. ## The numbers - **4 Nov 2026**: date INS Sahyadri arrived at Yokosuka Naval Base for Malabar 2026, per PIB - **4 navies**: India, Japan, the United States and Australia take part in Malabar 2026, per PIB - **29 Oct 2026**: date Sahyadri finished the India-Republic of Korea Navy bilateral exercise at Busan, per PIB ## What is at risk when navies do not practise together Every day, tankers, container ships and fishing boats cross the Indo-Pacific. A collision, a hijacking or a submarine contact can close a route that feeds Indian factories and kitchens. No one navy can be everywhere those routes run. That is why navies practise together before a crisis. They share radio habits, flying rules and how they hunt under the water. When those habits do not match, help arrives late or in the wrong place. [1] Exercise Malabar is one of the main drills India uses for that problem with three close partners: Japan, the United States and Australia. Those four countries also sit in the Quad grouping of Indo-Pacific partners. A guided missile stealth frigate is a warship built to be hard to spot on radar and able to fight in the air, on the surface and under the sea. [1] [2] ## Why one Indian ship is carrying so much of the load INS Sahyadri is an indigenous Guided Missile Stealth Frigate of the Eastern Fleet, meaning it was designed and built in India and sails with the Navy's east-facing fleet. On 4 November 2026 it arrived at Yokosuka Naval Base in Japan for Malabar 2026, the Press Information Bureau said the next day. [1] Yokosuka is a major Japanese naval base near Tokyo Bay. The Japan Maritime Self-Defense Force welcomed the ship. Vice Admiral Yagi Koji, Commandant of the Yokosuka District, and Shri R Madhu Sudan, Deputy Chief of the Indian Mission, attended the ceremony, per PIB. [1] The Times of India, citing the Indian Embassy in Japan, reported the same arrival day and the same two officials at the ceremonial reception, and placed Sahyadri at the centre of a wider run of Indian Navy deployments across oceans. [2] ## The setback is not a lost battle. It is a thin roster. A frigate cannot be in two seas at once. Before Japan, Sahyadri had just finished another partner drill. According to a separate PIB release, the ship concluded the India-Republic of Korea Navy bilateral exercise at Busan on 29 October 2026, after harbour talks and a sea phase with the Korean destroyer ROKS Munmu the Great. [3] DD News, the public broadcaster, confirmed that Busan schedule: harbour professional exchanges, then coordinated navigation, helicopter operations and joint manoeuvres at sea with ROKS Munmu the Great. [4] The Times of India adds that Sahyadri had reached Busan on 26 October after earlier work with Russia in the Indra series, and that the ship is in Malabar for a second year running. Those deployment details come from that report and the Embassy line it quotes, not from the Malabar arrival release itself. [2] So the tension is practical. One home-built frigate is hopping from Korea to Japan to stand in for India in a four-navy drill, while other Indian ships are busy elsewhere. If schedules slip or a ship goes unready, the Quad sea phase loses a partner on the water. [1] [2] ## What Malabar 2026 is meant to fix PIB says Malabar 2026 brings together the navies of India, Japan, the United States and Australia to improve operational coordination, interoperability and the exchange of professional expertise. Interoperability means crews can work each other's plans and gear without a long pause to translate habits. [1] The plan has two parts. A harbour phase for professional interactions and coordinated planning. Then a sea phase involving INS Sahyadri and participating units of the United States, Australia and Japan. [1] PIB links the visit to MAHASAGAR, which it expands as Mutual and Holistic Advancement for Security and Growth Across Regions, the Navy's label for wider maritime partnership work. The arrival note does not list which US, Australian or Japanese ships will sail in the 2026 sea phase. [1] ## What the releases still do not say The official arrival release does not give start or end dates for the 2026 harbour or sea phases. It does not name partner ships or aircraft. It does not say which serials, such as anti-submarine hunting or boarding drills, will be run this year. [1] The Times of India recalls that last year's Malabar sea phase, from 10 to 18 November, included anti-submarine warfare, Visit Board Search and Seizure, gunnery, underway replenishment and cross-deck helicopter work, with the harbour phase in Guam. That is a record of the previous edition, not a confirmed 2026 timetable. [2] Until a later official note fills those blanks, readers should treat Malabar 2026 as confirmed at the Yokosuka arrival and the four-navy line-up, with the detailed sea script still unpublished in the sources checked here. [1] [2] ## What to watch next - Whether a closing PIB or Navy statement lists the 2026 sea-phase serials and partner ships by name. - Dates for the end of Malabar 2026 harbour and sea phases, which the arrival release does not give. - Where Sahyadri sails next after Japan, after the Busan-to-Yokosuka hop. ## Sources 1.
