Discover why GE's Passport engine is B-52 ready.

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 Boreas 50 fiber optic gyroscope (FOG) is a highly accurate and reliable navigation technology. It’s the result of over 25 years of development in partnership with two research institutions. The gyroscope uses a closed-loop optical coil and an advanced spread-spectrum digital modulation technique to improve accuracy, stability, and reliability while reducing size, weight, power, and cost. Gyrocompass North-Seeking The Boreas range of fiber optic gyroscopes (FOGs) can determine heading without needing a Global Navigation Satellite System (GNSS) or a magnetometer. By sensing the Earth’s rotation, the system’s north-seeking algorithm can acquire an accurate heading. This is possible in static and dynamic conditions, even at high latitudes. Reliability Boreas 50 has been designed from the ground up for rugged reliability. Both the hardware and software are tested and certified to environmental and electromagnetic standards (MIL-STD 461 and MIL-STD 810H). The precision aluminum enclosure is waterproof and dustproof to the IP67 standard. The system is resilient to shock and vibration, allowing it to be used in extreme conditions. Industry-Leading SWaP-C The Boreas 50 FOG Series delivers industry-leading performance with a compact and lightweight design. Excelling in terms of Size, Weight, Power, and Cost (SWaP-C). Multi-Protocol Support The Boreas 50 features multiple interfaces, including Ethernet, CAN, RS232, 1PPS, RS422, and GPIOs. It supports industry standard protocols, including NMEA 0183, CANopen, 1PPS, and ANPP, as well as a wide variety of proprietary protocols. A rich, responsive embedded web interface provides full access to all of the device’s internal functions and data. Internal storage allows for up to one year of data logging.

High-power laser weapons targeting objects at 0.5 ~ 4.0km distances require optical components with sub-nm wavefront error precision. Our Company has successfully developed aspherical polishing and high-power laser coating technologies for Ø300 ~ 550mm optical components through defense project experiences. measurement technology 1) Laser Induced Damage Threshold(LIDT) - The evaluation to confirm the durability of optical components is called LIDT (Laser-Induced Damage Threshold), which is defined as "the maximum amount of laser radiation incident on an optical component when the expected probability of damage is zero" (ISO 21254). In other words, it represents the maximum intensity or power of laser that an optical component can withstand, making it a critical requirement in laser weapon systems. - Our company has established LIDT measurement technology and in-house facilities developed in accordance with ISO 21254 standards. When compared with LIDT test results from domestic and international companies during laser weapon system development, we have demonstrated measurement technology and accuracy that meets or exceeds industry standards. While overseas companies require more than one month for verification processes, our company can immediately provide reliable data through our LIDT system. 2) Cavity Ring Down Spectroscopy(CRDS) - When the reflectivity is 99.997%, this may not present significant issues in low-power laser applications. However, in high-power laser components, even the 0.05% of light that passes through the optical mirror can cause problems in vulnerable parts of the system, including rear optical instruments, bonded lenses, and control cables. Therefore, measurement and evaluation methods for high-reflectivity optical mirrors are extremely important. - Currently, the transmittance and reflectance of optical components are generally measured using spectrophotometers, but measuring reflectance levels of 99.5% or higher is not possible with this method. CRDS (Cavity Ring-Down Spectroscopy) technology is required to achieve measurement resolution beyond that of spectrophotometers, and our company has established this system to measure the reflectance of various optical components. This is a critically important technology for responding to high-power laser weapon system development requirements.

Main advantages of the PBS ECS systems include the possibility of cooling, heating and ventilation in one system, minimal power consumption, ecological operation without the need for a coolant and a compact design. Specific applications of the ECS systems include light combat aircraft AERO L-159 ALCA, jet trainers AERO L-39NG and L-39 Albatros, etc.

AquaShieldIR key benefits: Water repellency: creates a water-repellent surface on IR imaging lenses, preventing water droplets from adhering. This feature ensures clarity and visibility, even in rainy or foggy conditions. Enhanced visibility in wet conditions: by repelling water droplets, AquaShieldIR™ enables IR imaging lenses to perform optimally in wet conditions. Improved Image Quality: thanks to the preventions of water droplets and contaminants from adhering to the lens surface, resulting in improved image quality.
