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.

Quapason™ is a high-performance vibratory gyroscope from Safran Electronics & Defense, combining the compactness of MEMS with the reliability of Fiber-Optic Gyroscopes (FOG). It delivers exceptional robustness, ultra-low noise, and high signal stability, making it ideal for stabilization and inertial navigation in harsh environments. Used in weapon turret stabilization, avionics, and artificial horizons, it has surpassed 140,000 units delivered, proving its reliability and precision across civil and military applications.

Applied for the Localization Development Project of Core Components in Weapon Systems Conducted basic design for the development for mechanical Mine Sweeping Equipment for MSH, followed by submission of a proposal and presentation for in-person evaluation Patent : Mine Sweeping System with loT Based Functional Float

Brazing is bonding two or more pieces of metal by means of flowing a filler metal between the joint interfaces at a temperature below the melting point of the base metal. The filler metal, upon cooling to the solid state, forms a strong metallic bond throughout the joined area. Through Dip-Brazing, RF Systems manufacture 1. Brazed Antennas 2. Brazed Waveguides 3. Brazed Divider / Combiner

The SmartVDO Eye series AI cameras use the NVIDIA® Orin™ NX Super platform, offering a comprehensive, all-in-one AI monitoring solution. The NeuroEye-I series, designed for industrial inspection, features Sony high-resolution, high-sensitivity sensors and supports both rolling and global shutters for capturing detailed, high-quality images. The NeuroEye-S series, built for environmental safety, offers autofocus, auto-aperture, low-light night vision, and IP66 protection, ensuring reliable operation in harsh conditions. Combined with YUAN’s powerful AI development kit, QDEEP, AI models can be rapidly deployed and customized to enhance operational efficiency.

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.

# Key Features - Drone Detection and Neutralization > Detects and jams multicopter and suicide drones, and engages targets with gunfire. - Enemy Detection and Fire Support > Identifies personnel and vehicles within range, provides automatic target designation (digital reticle), and coordinates with squad-level weapons. - 360° Surveillance and Reconnaissance > Conducts all-round monitoring of bases and forward positions, deploys ahead in hazardous areas, and transmits real-time video. - Close Support and Resupply > Carries and delivers ammunition, water, and medical supplies to designated locations. # Expected Effects - Reduces soldiers’ combat burden, enhances survivability, and contributes to higher mission success rates. - Strengthens small-unit self-defense capabilities against drone attacks, which are emerging as a key threat in future battlefields.
