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.

Engine Parts, Overhaul

A super-evolution of the original platform brought about by the present-day tactical requirements and offering specialized features and functions specifically designed and fitted to provide top-notch efficiency, high operating speeds, a low recoil impulse, and a decisive and consistent feel. We took special care to design a weapon that offers very fast emergency reloads even in the most demanding of environments and situations, such as sports shooting, law enforcement or civil defense. The entire furniture set is AK compatible and thus the weapon can be fully configured to fit and use a wide array of accessories, making it suited for any preferences and all tasks.

The ACTUS® CORE-5 is the latest development of our Dot Sight lineup. It delivers the same high-end optical performance and legendary durability as our existing CORE Dot Sights, now with enhanced features based on feedback from professional users. The ACTUS® CORE-5 offers three reticle designs and improved ergonomics, with relocated illumination controls on the top for ambidextrous operation—ensuring seamless adjustments while staying clear of chest rigs and plate carriers when slung. A dedicated night vision override switch allows for instant adaptation to sudden lighting changes, while the CR2032 battery provides an impressive 20,000-hour runtime at Level 8 brightness.

We have taken the standard housing configuration of the P1 & P3 mounting dimensions while incorporating true differential pair contacts within the P1 & P3 dimensional constraints. P1 connector housing contains 21 position true differential pair blind mate contacts allowing board designers to carry high density differential pair signals from the LRU via motherboard to daughter-card plug in modules with a single connector P1 type housing.
