We, STX Engine, started with our business to be designated as a defense company in 1977 and established a factory for defense purposes in 1988. Moreover, we have grown into a largest defense diesel engine manufacturer by licensing with MTU. Based on the aforementioned fact, we manufacture and provide diesel engines for main battle tank, self-propelled artillery and armored vehicle to ROK Army, for destroyer, frigate, patrol vessel and support vessel to ROK Navy, for patrol vessel to Korea Coast Guard as well.

STX Engine produces medium speed engine driven power generation equipment that can satisfy customers 100% by ideally combining medium speed engines, which have been collectively produced at our Changwon factory since obtaining licenses from the mid 1970's from MAN ENERGY SOLUTIONS in Germany and NIIGATA POWER SYSTEM in Japan, with a power generation system designed with rich experience in the area of system engineering. By installing diesel engine power generation equipment in locations across Korea and overseas, such as on islands, remote areas, resorts, etc., where no public power supply is available, as well as industrial complexes and hospitals which require good source of power, and factories receiving expensive public power supply, etc., our customers can confirm the investment effect within a short period of time after experiencing the power supply we make available to them, as well as low installation and operation costs and maximized availability of the equipment.
