The Japan Ministry of Defense's (MoD's) Acquisition, Technology & Logistics Agency (ATLA) has provided more details about the configuration of the new Subaru UH-2 twin-engined, multirole helicopter that is entering service with the Japan Ground Self-Defense Force (JGSDF).

In a video released on 1 July via ATLA's official YouTube channel, the agency said that the new rotorcraft, which is based on the jointly developed Subaru Bell 412EPX commercial helicopter, features a Pratt & Whitney PT6T-9 Twin-Pac turboshaft engine and an integrated glass cockpit.

Other new aspects include a 30-minute dry-run capability by the main rotor's gearbox and the application of Subaru's proprietary laser-peening technology to improve mast-hub integration.

The helicopter's internal maximum gross weight is stated to be 12,200 lbs (5,534 kg), allowing it to transport greater loads than the UH-1J, which is set to be replaced by the UH-2. For instance, the agency said that the new helicopter can accommodate two reconnaissance motorcycles and their operators in the cabin. The UH-2 is also capable of stable landing on sea-going vessels and can be loaded onto cargo aircraft.

Besides the traditional cargo and troop transport role, the Japanese utility helicopter can deploy troops by parachuting or rappelling ropes, and also carry out humanitarian assistance and disaster relief (HA/DR) operations, specifically in the event of natural disasters.

With regards to mission systems, the video mentions that the UH-2 can be equipped with an airborne video camera to perform HA/DR operations and provide real-time data via a video transmission system. The aircraft will also feature warning systems, chaffs, and flares for self-defence.
