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.

Taesang manufactures Fixed Wing Aircraft using advanced closed die forging technology with SMS Group equipment. This process ensures precision, consistency, and superior quality for critical aerospace applications

It is equipped with advanced multi-sensor payloads such as EO/IR and LiDAR, enabling precise data collection in diverse environments. The drone is optimized for tasks ranging from infrastructure inspection to tactical surveillance. Its versatility allows operators to adapt quickly to different mission requirements with a single platform.

Every year, we celebrate World Space Week in October to honor scientists' contributions to space research and inspire the next generation of innovators. Honeywell has been a part of every NASA human space mission since the late 1950s, when our flight-control systems were installed on the X-15 Rocket Plane (shown above in a photo of Neil Armstrong after a research flight in November 1959).

Large mirrors are crucial in various optical systems, particularly long-range multi-spectral setups for defense, surveillance, and commercial use, like UAV optics and agricultural temperature monitoring. Aerospace applications, such as satellites and telescopes, are common. These mirrors come in different shapes and materials, including Al, Si, Ge, and Cu, spanning visible, UV, and IR spectrums. By using advanced CNC grinding, polishing, and diamond turning we provide precise surface forms, with tight tolerances, and multispectral performance. Our mirrors, up to 700mm in diameter, provide impressive specifications: 0.05% radius tolerance, less than 0.5Fr P-V irregularities, 0.1Fr RMS at 0.633μ, and sub-40Å RMS roughness. MKS Ophir's proprietary coatings enhance spectral performance and surface durability. Contact us to set a meeting at ADEX Seoul
