Victek was founded in 1990 and incorporated in 1996 as a defense and electronics component specialist, operating through two main segments: defense and civilian business.
In defense, the company produces electronic-warfare direction-finding systems, military power supplies, electro-optical equipment, IFF (identification friend-or-foe) devices, TICN (Tactical Information Communication Network) equipment, and other defense products.
Its flagship shipboard direction-finding system, SONATA, was jointly developed with the Agency for Defense Development, and the company separately developed a compact electronic-warfare system, ACES, to expand electronic-warfare revenue.
Its high-voltage power supply (HVPS) is applied across multiple defense systems, including the power module for the KF-21 fighter's AESA radar, export tank thermal-imaging units, and self-propelled artillery fire-control systems.
Its main counterparties are the Defense Acquisition Program Administration and prime contractors such as Hanwha Systems, giving it an indirect export structure through completed weapons-system makers.
In its civilian business, Victek operates unmanned public bicycle rental systems such as Seoul's Ttareungyi, also supplying related equipment such as QR terminals. In 2024, it established a subsidiary, Victek MHD-Rockland, to supply aircraft parts and conduct PBL and MRO business, extending into aviation maintenance.
Given this structure, Victek functions largely as a Tier-2 vendor supplying components and subsystems to larger defense prime contractors.
