The Hybrid Bi Ho self-propelled anti-aircraft system, seen here at ADEX 2015 in Seoul, combines guns and fire-and-forget SAM on one highly mobile tracked armoured platform. Source: IHS/James Hardy
South Korea's Doosan DST is marketing its latest Hybrid Bi Ho (Flying Tiger) self-propelled (SP) air defence system to the Asia-Pacific region and is one of two mobile air defence systems recently shortlisted by the Indian government.
The original full-tracked Bi Ho SP air defence system, also known as the K30, has been in service with the Republic of Korea Army (RoKA) for some years and is fitted with a two-person turret armed with twin locally manufactured Rheinmetall Air Defence KCB 30 mm cannon.
The Hybrid Bi Ho adds a pod of two Singung (Chiron) fire-and-forget surface-to-air missiles (SAMs) either side of the two-person turret that have an effective range of around 7 km and can engage targets up to a maximum altitude of 3.5 km.
The 30 mm cannons have a cyclic rate of fire of 600 rounds per minute and a maximum effective range in the air defence role of 3,000 m. They also have a secondary ground/ground role.
The target is first picked up by the TPS-830K surveillance radar mounted on the turret rear and then tracked using the panoramic day/night sighting (including forward-looking infrared) system, which also includes a laser rangefinder and is coupled to a computerised fire control system (FCS).
The Hybrid Bi Ho could also receive target information from another source and keep its own surveillance radar switched off to avoid the threat of anti-radiation missiles (ARM).
The Singung (Chiron), which is also known as the P-SAM by manufacturer LIG Nex1, is already deployed by South Korea in a tripod-mounted man-portable version and is fitted with a high explosive blast fragmentation warhead.
In a typical target engagement the Singung SAM would be used to engage targets at longer range with the 30 mm cannon being used to engage close in targets.
The Hybrid Bi Ho was originally developed to meet the requirements of the RoKA and following trials that were completed in 2014 is now in quantity production.
