Japanese fighters fly into India for Veer Guardian as UNICORN transfer stays on the table

Japan Air Self-Defence Force fighters are in India for Veer Guardian 26, a bilateral air exercise scheduled from 9 to 22 September. It is the first time Japanese fighters have deployed to India for the drill. The dates were locked in after Defence Minister Rajnath Singh and Japan's Defence Minister Shinjiro Koizumi met in New Delhi on 20 August and signed a Memorandum of Arrangement on Maritime Security Cooperation.

The August joint statement did more than name an exercise. The two ministers agreed to raise the complexity of bilateral drills, to bring unmanned systems into them, and to try short-notice exercises that test whether the two air forces can move without a year of planning. They also discussed special operations forces and how Japan's Self-Defence Forces might work with India's future integrated theatre commands.

Equipment is the slower file. Japan has described the UNICORN integrated communications antenna as its first defence-equipment transfer to India, building on a November 2024 memorandum that involves Bharat Electronics Limited. UNICORN is a single mast that folds several naval radios into one low-observable structure. The project is not new. What changed in August was a public push to finish it under Tokyo's revised Three Principles on Transfer of Defence Equipment and Technology. Koizumi and Singh also said they would talk about Japanese use of Indian yards for ship repair and about using Make in India lines for Japanese kit.

Before New Delhi, Koizumi visited Western Naval Command in Mumbai and INS Chennai. That itinerary was a message about the sea. India and Japan already share language on a free and open Indo-Pacific. Ship repair in Indian docks and a Japanese radio mast on an Indian hull are how that language becomes steel.

A fourth 2+2 meeting of foreign and defence ministers is supposed to convene in Tokyo later this year. The two sides also pointed at the Indo-Pacific Logistics Network, a disaster-relief airlift group, whose second tabletop exercise is due at Japan's defence ministry this month.

Veer Guardian is the part a camera can see. Japanese fighters on an Indian runway on 9 September are a fact that China can count. UNICORN, ship repair and theatre-command talks are the part that will or will not exist a year from now. The useful measure is whether the antenna contract is signed before the 2+2, and whether a Japanese ship actually ties up in an Indian yard for repair. Until those two events, the relationship still looks stronger on paper than on the dock.

Quad politics sits behind the schedule. The United States and Australia are the other two legs. A Japanese fighter deployment to India does not wait on Washington. That is why this fortnight matters more than another joint statement. It is also why the UNICORN file, dull as a radio mast, is the better test of whether Tokyo will sell and New Delhi will absorb.
