The EPL4000, like the EPL2000, is an all-in-one RU/DU/EPC/application server system that provides seamless outdoor LTE service without backhaul connection. It offers a service radius of several kilometers and is optimized for installation inside ships and vehicles.

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.

This rocket nozzle featuring conformal cooling channels and isogrid ribbing was manufactured using EOS Copper CuCP, a pure copper material optimized for additive manufacturing. The production required approximately 72 hours, taking advantage of the exceptional thermal and electrical conductivity of pure copper to meet demanding aerospace performance requirements. As one of the few companies in Korea capable of performing metal additive manufacturing with pure copper, we provide advanced technical expertise and support OEM production as well as collaborative technology development projects with various industrial partners. The showcased component was designed by nTopology and demonstrates the synergy of advanced design optimization with state-of-the-art copper additive manufacturing.

LLC-4000 is a cutting-edge 4K low-latency video encoder/decoder purpose-built for tactical operations, reconnaissance, and situational awareness in demanding environments. It delivers reliable real-time video transmission over narrow-bandwidth satellite links and tactical radio systems, enabling uninterrupted communication during critical missions. Engineered with a compact form factor and advanced compression technology, the LLC-4000 is well-suited for remote and mobile deployments where bandwidth is limited. Proven in operational use, the system has been successfully deployed by units of the Japan Ground Self-Defence Force, including amphibious rapid deployment and communications brigades, supporting a wide range of military field operations.

The first step toward armed helicopters The Bomb Rack Unit (BRU) is a device installed on a helicopter’s Stub-wing to mount various armaments such as rocket launchers and air-to-ground missiles, and it consists of a Pylon Unit and a Bomb Rack Unit. CTLA’s Bomb Rack Unit is equipped with a Boresight function that allows vertical (up/down) and horizontal (left/right) angle adjustments, and a solenoid-actuated free-fall weapon release (Jettison) method is applied. CTLA’s Bomb Rack Unit has passed the system tests for the Light Armed Helicopter (LAH) and received suitability certification, and it is currently in mass production.
