MSPO 2023: Hanwha Defense unveils Biho II mobile air defense system.

During the MSPO 2023 defense exhibition in Poland, the South Korean company Hanwha Defense is unveiling a new version of its Biho II mobile air defense system. This advanced system is built on the 8x8 wheeled chassis of the Tigon armored vehicle, marking a significant departure from previous Biho models that used a single 30 or 40mm automatic cannon capable of firing airburst ammunition.

Unlike its predecessor, this new model is based on the 8x8 wheeled chassis of the Tigon, which was initially revealed at the DX Korea defense exhibition in September 2018. The hull of the vehicle is made of fully welded steel armor but can be reinforced with appliqué armor to improve its resistance against ballistic and mine threats.

Under the hood, the Biho II is equipped with a power pack developed by Caterpillar. It includes a turbocharged and intercooled 6-cylinder inline diesel engine that generates 525 horsepower. The engine is coupled to a 4500SP electronically controlled automatic transmission from Allison, featuring six forward and one reverse gear.

The Biho II is fitted with an unmanned turret that can be armed with a 30 or 40mm gun capable of firing airburst ammunition. This new type of tactical anti-personnel explosive ammunition detonates in mid-air, causing airburst effect fragment damage to enemy targets.

Operated by a crew of three people—a driver, a commander, and a gunner—the Biho II is designed for efficiency and rapid responsiveness. In addition to its main armament, the vehicle can also be equipped with surface-to-air missile launchers that can be mounted on the side of the turret's roof.

The turret is also equipped with a small target radar mounted on its right side, with a maximum range of 15 km. Additionally, a surveillance radar is mounted on the roof of the turret, extending its maximum range to 35 km. The system can track fighter aircraft up to a range of 7 km and Unmanned Aerial Systems (UAVs) up to 3 km.
