STRATEGIC DIRECTION

Strategic Direction

Building on existing partnerships to expand prime registrations and collaboration scope.

We aim to participate in the supplier pools of leading primes—LIG D&A, Hyundai Rotem, and Korea Aerospace Industries— securing long-term contract foundations as a defense software and RF design partner, with extended engagement through MRO (maintenance, repair, and overhaul) services after delivery.
