The Nagajima YAGR-4b (Japanese: 近接航空支援用垂直離着陸対地攻撃機 YAGR-4b, Close air support and ground-attack VTOL aircraft YAGR-4b) is a dual-engine heavy jet VTOL combat aircraft developed and produced by Nagajima Aerospace Engineering and designed primarily for air support and ground-attack duties. It was developed from the earlier YAGR-3a and is the most mass-produced military jet VTOL vehicle in the world. It is one of the mainstay aircraft in the UNPF (United Nations Peacekeeping Force) as well as the APSOG. The YAGR-4b has been in use since 2084, and has been developed into many variants, including transport and drone variants.

The YAGR-4b is also less-commonly known as the "Type-78 CASGAVTOL", with the informal nickname of Suzumebachi (Hornet). It has the United Nations Identification Name of Hailstorm-A.


The YAGR-4b is a twin-engined jet VTOL aircraft. Its main method of propulsion and lift are the two large jet engine nacelles on swings on either side of the fuselage. Each engine is independently manoeuvrable and can also be rotated backwards 90 degrees to provide a great amount of forward thrust. Smaller vectored thrusters in the large tail provide control over pitch and yaw.

Heavily armoured, the YAGR-4b can withstand hits from up to 35mm rounds, and is hardened against EMP weapons. It is able to carry up to 4,200 kg of weapons on four under-wing hardpoints, and is also equipped with a 25mm cannon.

The layout of the cockpits is unconventional. The pilot of the aircraft sits in the upper cockpit while the gunner sits in the lower cockpit, allowing the gunner to have greater visibility over the ground to spot and acquire targets more quickly.


The YAGR-4b was developed by Nagajima Aerospace Engineering at the request of the old Japanese government. Developed started in 2045 and ended in 2082. Shortly after, the Japanese government made the wise decision to surrender and join the United Nations' Blue Zone. The YAGR-4b was then transferred to UN use.
