Hydraulic top bracing is an attenuation device installed between the main engine and the hull of the ship to reduce thermal expansion and vibration from the main engine to natural frequencies. The operating principle is an automatic control operating system through in/out and on/off the operating range of the hydraulic top bracing according to the rpm of the main engine. The number of hydraulic cylinders per engine is typically 2, 4, 6 depending on the type of engine, up to 8 are installed if necessary, and 1~2 of control panels are installed.

FIRSTEC is providing key components of guided weapon, such as Actuation System, Gudiance Control Unit, Fire Control Unit, and wire harness, to complete systems such as Hyunmoo, Raybolt(Hyungung), Bigung(Poniard), M-SAM II(Cheongung II), L-SAM etc. applying them to each business.

EveryDrone is a web-based tool for developing high-performance drones. It enables 3D model creation, virtual wind tunnel testing(CFD), and structural analysis, all without software installation. Even without prior simulation knowledge, anyone can follow the workflow to easily complete simulations.

A ground control system that establishes unmanned aerial vehicle missions, controls aircraft and mission equipment, reads image information, and transmits it to higher-level units.

High-quality aerospace-grade aluminum forgings, produced from 6000 and 7000 series ingots sourced from reputable foundries. Our company specializes in forging and heat-treating to meet specific customer requirements, including ring and plate shapes, for defense industry applications.

This is the UAV launchers capable of launching the fixed-wing UAVs even on mountainous terrain, field, ships without sufficient runways to take off. It is designed to be the most powerful and easy to operate to take off the fixed-wing type UAVs of various specifications(Take-off weight, Take-off speed, and allowable G-force) into the air. It provides an interface that standardizes the shuttle for any type of unmanned aviation vehicle, and is easy to mount and to avoid take-off interference. A specially designed and manufactured hydraulic actuator is used to fully cope with the take-off weight of the aircraft, and a proprietary accumulator to allow a wide range of launch speed control. And multiple pulleys are equipped to ensure acceleration performance.

MQ-9B SkyGuardian® is the next generation of remotely piloted
aircraft systems (RPAS), delivering persistent intelligence,
surveillance, and reconnaissance (ISR) around the globe.
SkyGuardian is designed to fly over the horizon via satellite for up
to 40 hours in all types of weather and safely integrate into civil
airspace, enabling joint forces and civil authorities to deliver real-time
situational awareness anywhere in the world—day or night. Featuring
a longer wingspan than its predecessors at 79 ft (24 m), the aircraft is
outfitted with the revolutionary Lynx® Multi-mode Radar, an advanced
electro-optical/infrared (EO/IR) sensor, and automatic takeoff and
landing capability. In addition to its industry-leading endurance and
superior surveillance capabilities, SkyGuardian seamlessly integrates
with its users’ other platforms, systems, and podded technologies,
dramatically expanding the aircraft's multi-domain mission set
