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.

The ACTUS® ARKS16 (1–6X24mm SFP) Riflescope is designed for precision and durability, meeting the needs of professional users in a wide range of environments. With a Second Focal Plane (SFP) optical design, it enables fast and accurate target acquisition at various magnifications. The illuminated reticle ensures smooth and reliable targeting even in low-light conditions, such as during dawn or dusk. Built to perform in diverse operational environments, the ACTUS® ARKS16 is the ideal sight for users requiring superior performance when it matters most.

The ASN-157 was developed to meet the ongoing need for helicopters with reduced size and weight avionics. The ASN-157 system has an accuracy of 0.15 percent of total velocity, weighs less than 13 lbs., consists of one line-replaceable unit, and has a predicted mean time between failure of over 7,300 hours.

EM21 is designed to be used behind the EOST EDS Red Dot Reflex Sight. EM21 can be mounted right behind the EOST EDS (or any of other dot and holographic sight) to give 3 times magnifying view. EM21 helps shooter convert the optical magnification so that he can have better target acquisition and fast target engagement capability. The ability to transition between the two distances almost instantly and still maintain weapon accuracy is easily achieved with our EM21. Simply switch the magnifier out of the way for a quick 1X targeting. EM21 can be used for hunting/recreational purpose.

The SDI170 IMU is designed for demanding, mission-critical, rugged environments and ideal for continuous use applications with no wear-out components, highly linear accelerometer performance and longer life compared to competing alternatives. It is constructed with EMCORE’s latest generation quartz gyros, quartz accelerometers, and high-speed signal processing to achieve outstanding precision performance. The solid-state quartz sensors and hermetically sealed IMU construction provide reliable MTBF and a 20-year operating and storage life. Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection and flexible input power compatibility make the SDI170 IMU easy to use in a wide range of higher-order integrated commercial and defense system applications.
