Japan's navy gets a home repair base for its V-BAT drones under a Shield deal with NIPPI

US drone maker Shield has signed a contract with Japan's NIPPI Corporation that makes the aerospace firm its main provider in Japan of maintenance, repair, overhaul and training for the V-BAT uncrewed aircraft flown by the Japan Maritime Self-Defense Force. The companies announced the agreement in Tokyo on 12 November.

Under the deal, NIPPI will provide technical and maintenance support for the V-BAT directly to the JMSDF and set up its own capability inside Japan to service Group 3 uncrewed aircraft, a class of larger tactical drones. Shield described it as the first domestic maintenance agreement of its kind for the type in Japan. Neither company disclosed the value of the contract, how long it runs or how many aircraft it covers.

The stated goal is readiness. Shield says keeping repair work in Japan will shorten turnaround times and remove much of the need to send components back to the United States, while building a Japanese workforce able to support V-BAT operations over the long term. The company also said NIPPI could later support V-BAT programmes in other branches of the Self-Defense Forces, although no such expansion has been agreed.

NIPPI, founded in 1934 and now a wholly owned subsidiary of Kawasaki Heavy Industries, brings a long record of military aircraft work. It operates from Yokohama and from facilities next to Naval Air Facility Atsugi, and Defense War Room reported that it has been a depot-level maintenance contractor for US Navy and Marine Corps aircraft in Japan since the early 1950s, working on more than 14,000 of them, including MH-60 helicopters, EA-18G Growler electronic attack jets and MV-22 Osprey tiltrotors.

Sumisho Aero-Systems, the Japanese trading company that has handled the V-BAT purchase for the JMSDF since the programme began, will keep its role as the link between Shield and Japanese government customers. Shield has also set up a dedicated office in Tokyo to support its customers and partners in the country.

The support contract follows a fast acquisition. Japan's cabinet approved the purchase of six V-BAT systems on 27 December 2024 under a fiscal 2025 budget that set aside 4 billion yen to give the navy's planned patrol vessels their own shipborne surveillance, Shield confirmed the selection in January 2025, and the JMSDF announced that the first aircraft had arrived at Yokosuka in December 2025, according to Defense War Room.

The V-BAT, designated MQ-35A in US service, is a tail-sitting drone that takes off and lands vertically before switching to wing-borne flight, and its enclosed ducted fan keeps exposed rotor blades away from crowded ship decks. Manufacturer figures cited by Defense War Room give it a maximum take-off weight of 75 kilograms and more than 12 hours of endurance when carrying an electro-optical and infrared camera. The US Navy and US Coast Guard also fly the type.

In Japanese service the aircraft is tied to the new Sakura-class patrol vessels, a 1,900-ton design whose lead ship is due to be commissioned in January 2027. JMSDF officials have also said the drone is under consideration for the upgraded Mogami-class frigate, Defense War Room reported.

The arrangement also bears on surveillance in the seas near Taiwan. Defense War Room argued that a repair chain running across the Pacific would limit how often the drones could fly as demand for surveillance grows in the East China Sea, and that a home depot run by a firm already servicing US Navy aircraft near Atsugi could become a sustainment hub for a drone type that US forces also operate in the region, although support for US units is not part of the announced scope.
