• Developing dual-use UAVs for civil and defense applications
• Automating the transport of heavy cargo with MHI's multi-purpose medium-sized UAV
• Accelerating the transport of medications using a VTOL (vertical take-off and landing) UAV capable of flying long distances at high speed

TOKYO, July 31, 2025 - (JCN Newswire) - Mitsubishi Heavy Industries, Ltd. (MHI) participated in a practical training exercise held on July 17 at the Japan Ground Self-Defense Force (JGSDF) Asaka Garrison (Nerima-ku, Tokyo), aimed at improving response capabilities in the event of an earthquake centered on the Tokyo metropolitan area. The training was conducted by the JGSDF Eastern Army in cooperation with local governments, with MHI joining at the request of the Japan UAS Industrial Development Association (JUIDA). MHI conducted training to transport relief supplies to isolated disaster victims using its medium-sized multirotor uncrewed aerial vehicle (hereinafter "medium-sized UAV") currently being developed by its Commercial Aviation Systems division, and the VTOL (vertical take-off and landing) UAV being developed by the Integrated Defense & Space Systems division.

The medium-sized UAV is being developed for a variety of purposes, such as transporting relief supplies in the event of a disaster, providing logistics support to remote islands and mountainous areas, and conveying materials for construction work on power transmission towers. It has conveyance functionality with enhanced wind resistance during takeoff and cruising, and an automatic unloading function that allows the cargo to be lowered at the destination with a winch from a hovering state without having to land. For this exercise, MHI conducted a loading demonstration of relief supplies, and a flight demonstration. Going forward, MHI will pursue further functional improvements such as incorporation of satellite communication capabilities, and extension of the cruising range with a hybrid power system.(Note)

The VTOL UAV is being developed for the purpose of quickly delivering relief supplies to remote islands and ships in transit. It is capable of high speed flight over long distances of up to 1,000 kilometers, and can take off and land even in places without runways. For this exercise, MHI took advantage of the maneuverability and vertical take-off and landing capabilities of the VTOL UAV to demonstrate quick delivery of medicines to disaster areas.

MHI will continue to pursue the development of dual-use UAVs with consideration for both civil and defense applications, and through their use, work to provide solutions for various societal challenges.
