It is amazing how long it has been taking for the Koreans to figure out how to domestically produce one of their key defense systems:
South Korea’s arms acquisition agency has decided to equip third batch of K2 Black Panther main battle tanks with a German transmission system, a part of the tank’s power pack that includes a locally developed engine.
The decision is a blow to a 15-yearlong effort to replace the German RENK transmission system with an indigenous one, which local industry expected would pave the way for exporting the tank. (…….)
The failure in local transmission development has also caused setbacks for the tank’s deployment in the South Korean Army.
The Black Panther was co-developed by the state-run Agency for Defense Development and Hyundai Rotem, a defense business arm of Hyundai Motor, to replace M48 Patton tanks and earlier models of K1 tanks that have been service since the 1980s. Prototypes were unveiled in 2007.
Mass production of the first 100 units was approved in 2011, with deployment scheduled for the following year, but the effort was delayed over a faulty engine and a lack of progress on a locally produced transmission. The government then decided to use the German-made power pack consisting of the MTU 883 diesel engine and RENK transmission system for the first batch.
The tanks entered service in 2014, and in that same year, local developers announced they succeeded in developing a 1,500-horsepower power pack that could be installed on the second batch of 100 tanks. However, the deployment of the second batch also faced delays, as the S&T Dynamics-made transmission system repeatedly failed to prove its reliability and durability under transmission production standards, which require a system to run without issue for 320 hours. The second batch of K2s were eventually delivered in 2019.
