[Defense Column] Russia's 'T-80U' Tank Received Instead of Money

[Kim Daeyoung, Military Analyst] In 1983, the Soviet Union developed the T-80U tank to counter the latest tanks of the United States and NATO (North Atlantic Treaty Organization). The T-80U tank was adopted by the Soviet Army in 1985, and today, Russia?the country that developed it?along with South Korea and Cyprus, are considered its main operators. South Korea began importing the T-80U tanks in September 1996.

The T-80U tanks were introduced through the "Bulgom Project." In 1991, the South Korean government provided the Soviet Union with a $1.47 billion economic cooperation loan. Initially, $3 billion was planned, but only about half was paid due to the sudden collapse of the Soviet Union. However, Russia, which succeeded the Soviet Union's debts, faced poor economic conditions and eventually found it difficult to repay the principal and interest. In July 1995, South Korea and Russia signed an agreement to repay in kind instead of cash. Accordingly, from 1995 to 1998, raw materials, helicopters, and defense industry goods were to be repaid annually, among which the defense industry goods import project was the Bulgom Project.

The T-80U tanks introduced to South Korea were newly produced at the factory at the time, featuring the latest model equipped with the new 1,250-horsepower Klimov GTD-1250 gas turbine engine. About 30 T-80U tanks were imported, initially as training tanks brought in to study "enemy equipment," i.e., the enemy's weapon systems. However, the Army later officially adopted the T-80U tanks as standard equipment, and they are currently used in frontline units for combat. The Army's adoption of the T-80U tanks, originally enemy equipment, as official military equipment is a rare case worldwide.

The T-80U tank, which uses an autoloader, carries a crew of three and can fire anti-tank missiles from its main gun. Uniquely for a tank, it is equipped with a gas turbine engine, which is mainly used in aircraft. Compared to diesel engines commonly used in tanks, the gas turbine engine is lighter and has better cold-start performance. In fact, Russian units deployed in cold regions operate T-80U tanks. The gas turbine engine has a simple structure and is advantageous for maintenance and repair. It also produces less noise compared to diesel engines.

However, it has drawbacks such as high production costs and poor fuel efficiency. The T-80U tank can travel at a maximum speed of 70 km/h on roads. The T-80U tanks deployed in the Army reportedly made a strong impression on many military officials. Unlike the Army's tanks, which mainly used 105mm guns at the time, the 125mm main gun mounted on the T-80U demonstrated powerful firepower. Additionally, the autoloader and the ability to fire anti-tank missiles from the gun distinguished it from the tanks operated by the Army at that time. Because of this, the South Korean military considered importing more T-80U tanks.

However, opposition from domestic defense companies and difficulties in friend-or-foe identification led to the plan being quietly shelved. Nevertheless, the advantages of the T-80U tank were reflected in the development of the Army's K2 tank. In particular, the K2 tank uses a neutron shielding liner to block radiation in consideration of combat during nuclear war, a technology said to have originated from the T-80U tank.
