What AEC Skyline does

AEC Skyline is a privately-held Dutch defence and aerospace services company headquartered in Bosschenhoofd, Netherlands, founded in 1991 and controlled by CEO Stef Have through the Forum Group. The company operates through three subsidiaries: Skyline Aviation (contract air services), Skyline CDS (Critical Data Solutions for C4ISR & Cyber), and S2IX International (secure information management software, acquired November 2025). Its core business is delivering realistic and cost-effective training and ISR support to armed forces and public security organisations, with primary customers including the Netherlands Ministry of Defence, Belgian Ministry of Defence, Royal Netherlands Air Force, USAFE, NATO exercises, and Royal Netherlands Army units.

AEC Skyline's technical portfolio spans contract air platforms (Learjet 36A, L-39 Albatros, GA8 Airvan, PC-12) configured for JTAC Close Air Support training, adversary air (ADAIR) training through its exclusive teaming with Top Aces, electronic warfare training, target towing, and remote sensing. The Sky Warden ISR Strike Aircraft (Air Tractor AT-802U based) provides 7.7+ hours of persistent operations with WESCAM MX-15/MX-20 EO/IR pods, Link-16, ROVER datalinks, and Persistent Systems MPU5 MANET radio. On the C4ISR side, the company is an official reseller and systems integrator for L3Harris datalinks (ROVER, VORTEX), Persistent Systems Wave Relay MANET (MPU5, GVR5), Nokia/Fenix Group Banshee tactical radios, Haivision video encoding (Command 360, Makito, Kraken, Falkon), Juggernaut.Case ruggedized devices, Elistair tethered drones, Milrem Robotics UGVs, and TrackDeep counter-UAS. The proprietary S2IX software provides NATO FMN-compliant secure information exchange with Zero Trust architecture validated at CWIX exercises.

The company generates revenue through multi-year government defence contracts (Netherlands MoD 5-year contract awarded July 2022, Belgian MoD CAS contract May 2025), C4ISR hardware resale with integration margins, OEM systems integration services, and increasingly software/subscription revenue via S2IX and Whisper secure roaming eSIM services. AEC Skyline is accredited under MAR-OPS 1&2, MAR-M, and MAR 145 (first commercial Netherlands company so accredited) and certified to ISO 9001:2015, ISO 14001:2015, and ISO 27001:2022. Operations span the Netherlands (Bosschenhoofd, Eelde), Germany (Zweibrücken), Belgium, and exercises across Europe and the Caribbean.

Expansion highlights6 records

Broad incumbents

• Saab: Swedish defence prime offering combat aircraft, C4ISR systems, electronic warfare and training across NATO. Comparable to AEC Skyline in the C4ISR and training portfolio, though at much greater scale.
• CAE: Global defence training and simulation prime serving NATO militaries with synthetic training solutions and live-virtual-constructive offerings. Comparable on military training services to NATO allies, though much larger and broader scope.
• QinetiQ: UK-headquartered defence and security technology and services company operating air training ranges, target towing and C4ISR test services. Comparable to AEC on contract military aviation services to European NATO customers.
• Kongsberg Defence & Aerospace: Norwegian defence technology company offering tactical communications, C4ISR and remote weapon stations to NATO customers. Directly comparable to AEC's C4ISR integration business, particularly on tactical radios and command systems.

Emerging players

• Systematic: Danish defence software company offering SitaWare C4ISR suite widely used across NATO. Highly comparable to the S2IX software business acquired by AEC Skyline in November 2025 — both target NATO mission networking interoperability.
• Persistent Systems: US-headquartered MANET radio pioneer (MPU5, Wave Relay) — one of AEC Skyline's flagship OEM partners for tactical radios. Directly comparable on military tactical communications technology, though AEC is a reseller/integrator while Persistent sells direct.
• Milrem Robotics: Estonian unmanned ground vehicle manufacturer whose THeMIS and Type-X platforms are integrated by AEC Skyline as part of its manned-unmanned teaming offering. Comparable to AEC's unmanned systems integration and trials work.

Direct peers

• Draken International: US-based commercial adversary air and JTAC training provider operating a large fleet of former military jets. Closest US analogue to AEC Skyline's Skyline Aviation division — directly comparable on contract air services for military customers.
• Top Aces: North America's leading commercial adversary air (ADAIR) provider operating F-16, A-4, Alpha Jet and Learjet 35 aircraft with Advanced Aggressor Mission System. AEC Skyline's exclusive teaming partner for joint ADAIR and JTAC training in Benelux and the Nordics — directly comparable in mission, business model, and customer base.
• ATAC (Airborne Tactical Advantage Company): Commercial adversary air provider serving US Navy, USAF and allied forces with a fleet of Hawks, Mirages and L-39s. Closely comparable to AEC Skyline on JTAC and CAS training mission for military customers.
