VICTEK Co., Ltd.

VICTEK started in July 1990 making power supplies for the Korean military, and the ACES electronic warfare family grew out of that. The company now runs two businesses that look nothing alike. On the defense side it is the domestic specialist in warship electronic support, with a product line graded by platform. ACES-I, fielded under the Korean designation SLQ-201K, equips surface combatants above 250 tons and completed sea testing aboard ROKS Andong in June 2019. ACES-II is the customised shipboard variant. ACES-III is the submarine system, and VICTEK describes it as the first submarine electronic warfare equipment developed entirely with Korean technology, using six channel direction finding to detect, analyse and classify emitters before cueing the combat system. The company also won the local development contract for the P-3C electronic support suite flown by Korean maritime patrol aircraft, covering the signal processor, RF divider and wideband receiver, and it has been in volume production of identification friend or foe equipment since 2009. Few suppliers anywhere cover both the receiver that finds an emitter and the high voltage supply that feeds the transmitter answering it, and VICTEK does both in the same building. That vertical reach shows up in the pricing.

Power conversion remains the backbone. VICTEK builds high voltage power supplies that drive travelling wave tubes in shipboard and airborne jammers, including a unit able to run four mini TWTs together or individually, plus HVPS for satellite communication vehicle terminals, general military power supplies, uninterruptible supplies, power modules, battery management systems and a rectifier for the impressed current cathodic protection system that keeps FFX hulls from corroding. Related to that are high power amplifiers in microwave power module and TWTA formats. A fourth line covers signal processing and control hardware. It includes an airborne terminal linking helicopter weapon systems to surveillance and command networks, a vehicle and man portable tactical computer, a 21.5 inch touch panel military computer built into the compact SLQ-201K console, and a rugged 7 inch handheld with GPS and radio interfaces.

The civil side is a genuine second business rather than a sideline. VICTEK supplies smart public bicycle sharing systems to Korean cities, comprising docking terminals with GPS and electronic self-locking, kiosk-free stations, relocatable stands and a patented cascade mechanism that lets one bike lock to another. Electrical facility and information communication contracting sits alongside it. Newer work includes LiDAR for maritime unmanned systems and high voltage supplies for digital X-ray generators. The company moved its headquarters from Icheon to Yeonsu-gu in Incheon in 2024, employs roughly 250 people, reported sales near 82.9 billion won and has traded on the KOSDAQ since 2003. It has been recognised by the Defense Agency for Technology and Quality and by DAPA for procurement performance.
