We are one of the world's leading manufacturers of both military and commercial aircraft ground support equipment. Hydraulics International, Inc. is proud to be one of a few small companies having the total self sufficiency in the design and fabrication of aerospace ground support equipment.

A key weapon system of the Korean missile defense system that can effectively respond to various enemy air threats. The Cheongong is a medium-range surface-to-air guided weapon that provides enhanced regional air defense capabilities that can effectively respond to various enemy air threats infiltrating from medium and low altitudes, and is the core weapon system of the Korean Missile Defense System (KAMD). The simplification, lightweight, and maneuvering of the guided weapon system have improved operational efficiency and survivability, and excellent technology such as multi-target simultaneous response capability, high-altitude interceptor guided munitions, and electromagnetic interference countermeasures have been reflected. Key Features: SimulTaneous Capable of interlocking superior, adjacent systems, or conducting simultaneous engagement operations by a single battery Multi-Target A three-dimensional phased array radar (MFR) with target detection, tracking, and enemy identification capabilities, and has multi-target detection capabilities Launcher Vertical launcher capable of remote operation of wired and wireless (maximizing the effect of responding to all-round targets)

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.

The MIL-DTL-5015 series of connectors were developed as military standard connectors and applied to various military equipment, it is also used in general industries, medical care, electric vehicles, robots and automation facilities based on its high durability and reliability. This series is threaded coupling and the connection between the contact and the wire is based on soldering. It can be used compatibly with third-party products of the same standard since it is produced according to military standards.

Lumir, in collaboration with the Electronics and Telecommunications Research Institute (ETRI), developed and integrated this device for lunar exploration aboard Danuri (KPLO, the Korea Pathfinder Lunar Orbiter), Korea's first lunar probe. This device successfully demonstrated its performance by receiving BTS music videos transmitted from the Moon to Earth, achieving Technology Readiness Level (TRL) 9.
