The EL4000 is an RU/DU-integrated LTE outdoor base station that provides long-distance LTE service outdoors and has been supplied through KT for the Ministry of Oceans and Fisheries’ LTE-M network.

The Nebula connector employs the renowned Hypertac hyperboloid contacts as the bedrock of its high reliability providing immunity to shock and vibration fretting and over 100,000 mating cycles. These features combine with current carrying capacity up to 1.5 Amps per contact and low insertion / extraction forces to provide significantly enhanced quality and reliability performance compared with other more commodity connector solutions. Available for direct mounting to PCB, the Nebula Series supports independent function for all its 22 contacts. It also offers optional quarter-turn locking hardware for faster connector securing and to prevent unintentional separation.

Hyundai Rotem's UGV has adapted the top-notch autonomous driving technoolgies from Hyundai Motor Group, capable of search and reconnaissance missions as well as munition transport. Fielded in real operation after approval by the ROK Army in 2021, its technologies were also appreciated in major events such as National Armed Forces Day and Combined Joint Live Fire Exercise.

Supported by a rugged internal combustion engine compatible with heavy fuels, Reliant delivers over 10 hours of persistent ISR without runways, launchers, or recovery gear. Designed for high-wind, high-altitude, and denied environments, Reliant excels where legacy platforms fall short. Dual swappable payload bays support ISR, SIGINT, or EW missions, while onboard edge AI processing enabled by NVIDIA Jetson Orin NX modules delivers real-time threat detection and adaptive rerouting, even without connectivity. The platform can be deployed by a two-person team in under 10 minutes using a compact 10×10-meter footprint for launch and recovery from rooftops, vehicles, ships, or remote terrain. With an IP55-rated, all-weather design and reliable GNSS-denied navigation, Reliant gives operators the flexibility and resilience required to operate in complex, contested battlespaces.

KJF designed and fabricated passenger, service and cargo door assembly toolings for sukhoi superjet 100.

aviation fuel refueling cart : Mobile refueling cart that can easily refuel light aircraft and helicopters Sump recovery system : Collect the drained/sumped aviation fuel from the aviation fuel refueling system, easily sample and test it, and then decide whether to drain it or return it to the system. Aviation fuel refueling system : The aviation fuel refueling system is compactly constructed with a skid for easy use and installation.

Tactical Information Communication Network (TICN), a core system for network-centric warfare (NCW) It is a communication-based system that guarantees real-time command and control of reconnaissance, surveillance, command decision, and true strike in network-centric warfare (NCW), including network management system (TIPS)/switching system (TIPS), tactical mobile communications system (TMCS), and small-capacity transmission system. It is divided into five subsystems: (LCTRS), High Capacity Transmission System (HCTRS), and Multi-band Multi-Channel Multi-function Radio (TMMR).
