K22 IFV is the Royal Joseon Armed Forces's next-generation infantry fighting vehicle. It was developed to replace part of the K200 and complement the K21.
K22 was developed by improving the AS-21 Redback IFV to meet the needs of the Royal Joseon Armed Forces.
History
Design
K22 replaced the existing K-21's aluminum composite armor with steel armor, and fitted additional armor to meet the needs of the Royal Joseon Armed Forces. After all these improvements, the K22 had a stronger defense than the K21, but it weighed significantly more than the K21. Because of this, the K22 had to be equipped with a more powerful engine than the K21. The K22 addressed this issue by installing a K9 self-propelled howitzer's power pack engine, which had more power than the K21's engine.
K22's tracks are composite rubber tracks(CRT) manufactured by Soucy Defense(Canada). Rubber tracks are lighter in weight than conventional steel tracks, but can retain the vehicle's load, and reducing vehicle vibration/noise and increasing fuel efficiency. In addition, CRT is easier to maintain than steel tracks. While conventional steel tracks need to be replaced every 5000 km and rubber packing needs to be replaced every 500 km, CRT only needs to be replaced entire tracks once every 5000 km without rubber packing replacement. In addition, CRT can be repaired by welding by troops using dedicated tools in the field.
