Long-term, stable aftermarket demand once fieldedSource: CRENGINE Global Defense MRO Business Plan (2026). Market size and growth are estimates.
Limits of the prime-contractor-led export model
- Small importers such as Finland, Norway, Estonia and Egypt lack timely consumables and local maintenance infrastructure
- US/European OEM supply chains need months to years for parts because of labor shortages and aging equipment
- Obsolescence and delays translate directly into capability gaps and security risk

Six business areas
Weapon-system MRO
Naval (smart MRO and digital twins, engine and propulsion overhaul, reverse-engineering of obsolete parts, hull and green tech) and Army (outsourced maintenance of K1, K2, K9, K-55A1, KAAV, K21; sub-system module maintenance; local centers).
Defense spare parts (CSP)
Consumables for M109 and LVDT (tracks, road wheels, support wheels, HSU) via domestic partners or own production, with a cooperation framework with Hanwha Aerospace.
IPS element development
Integrated product support manages the whole life from requirement to disposal. We develop the 12 IPS elements, training content and electronic manuals.
AI smart maintenance (CBM+)
Auto-generated digital twins per combat vehicle with field failure history and live data to predict failures — higher availability, lower cost and time.
Training center
Networked multinational training with security protocols; Meta Quest 3 and HTC VIVE first; VR training for K9 User Club countries.
Non-weapon equipment export
Export of body armor (protection levels IIA–IV), field gear, boots, helmets and ALICE packs.

Combining 32 years of defense know-how
with XR and AI
Digital twins per combat vehicle are generated automatically and combined with field failure history and live operating data to predict failures.
- Higher availability through failure prevention
- Lower sustainment cost and maintenance time
- Optimized maintenance support and logistics

Let's start global MRO together
Parts export, maintenance, training and AI predictive maintenance. We welcome cooperation proposals.
