Contribute the Enhancement of Armed Forces with Continuous Technology Development Designed for replacing the Republic of Korea Army(RoKA)’s aged attack helicopter (500MD, AH-1S), the LAH(Light Armed Helicopter) Project is the one that aims to develop a cutting-edge armed helicopter suitable for the modern battlefield. Through the synergy of maximizing commonality in subsystems and parts with LCH(Light Civil Helicopter), KAI will reduce the development, production, and sustainment cost ultimately to be a bridgehead for a global helicopter market. The first flight of LAH was successfully conducted in 2019. KAI aims to complete the development of LAH in 2023.

ARDRONIS는 로데슈바르즈의 드론 대응 솔루션 제품군입니다. 복합 시스템 접근 방식으로 고객이 각각의 고유한 최종 사용자 요구사항에 따라 악의적이고 비협조적 위협을 탐지-식별-위치 확인-추적-검증-대응할 수 있습니다. ARDRONIS가 RC 드론 활동을 탐지하면 드론 신호의 유형을 자동으로 분류하고, 드론의 방향과 조종자를 확인한 다음, 드론이 목표물에 도달할 수 없도록 무선 제어 링크를 차단합니다. 대부분의 상업용 원격 제어 드론은 최신 주파수 가변 파형인 FHSS(Frequency Hopping Spread Spectrum)를 통해 제어합니다(업링크). 기타 일반적인 드론 유형은 Wi-Fi을 통해 제어합니다(업링크). 드론에서 전송하는 신호(다운링크)는 일반적으로 FHSS, Wideband 또는 Wi-Fi 신호입니다.

The Haigh-Farr Wraparound™ is a self-contained omnidirectional antenna for cylindrical or conical shaped bodies. A single point feed is used and no external splitters, combiners or cable harnesses are required for installation. The antenna is conformal, and may be mounted flush, or on the exterior of the vehicle. Designs are available from 300 MHz to 13 GHz with typical applications including Flight Termination, GPS, Telemetry, Data Links and Transponder. Multiple antenna elements may be combined within the same physical Wraparound™, providing multi- band capability in a single, compact package. Wraparound™ antennas have been flown on vehicles from subsurface sea to space, including high-mach kinetic kill weapons, high-G projectiles and re-entry vehicles. The Wraparound™ has been qualified for use on several high performance vehicles flown on test and launch ranges throughout the United States and Europe. For high aero-heating applications an ablative heat shield may be added to the antenna for additional thermal protection.

Green Optics possess proprietary CVD-based Zinc Sulfide (ZnS) production technology for defense and industrial multi-wavelength optical materials. We have core technological capabilities to manufacture high-quality ZnS products tailored to meet diverse customer requirements. ZnS Material Optical Performance and Processing ZnS materials produced through CVD processes provide high transmittance exceeding 70% in the SWIR wavelength range (8-12 μm). When these materials undergo additional Hot Isostatic Pressing (HIP) treatment, the crystal structure undergoes recrystallization, improving transmission characteristics to achieve over 70% transmittance in the visible (VIS) wavelength range of 0.45-0.8 μm. This process extends the application range of optical materials previously limited to SWIR and LWIR bands, delivering superior optical performance across multi-wavelength regions from VIS to LWIR. Material Specifications: - STD-ZnS (Standard ZnS Material): Manufactured via CVD process, exhibits transmittance exceeding 70% in LWIR wavelengths (8-12 μm) with high physical hardness (Knoop hardness: 210 kgf/mm²). - MS-ZnS (Multispectral ZnS): Converted from STD-ZnS through HIP processing, extends wavelength range into the visible spectrum. While crystal structure recrystallization during this process reduces hardness somewhat (approximately 150 kgf/mm²), it still meets MIL specifications. This dual-processing approach enables comprehensive wavelength coverage while maintaining military-grade durability standards.
