INTA — Spain's National Aerospace Institute

The Instituto Nacional de Técnica Aeroespacial (INTA) is Spain's leading public research organization for aerospace and defense technology. Operating under the Ministry of Defense, INTA conducts critical testing, certification, and R&D for Spain's defense sector and international aerospace partners.

The Centro de Ensayos para Unmanned Systems (CEUS) in Huelva is INTA's specialized facility for unmanned aerial vehicle (UAV) testing, training, and certification — supporting next-generation drone development for defense, surveillance, and reconnaissance applications.

⚠ Challenge

INTA required reliable, specification-grade Jet A-1 supply for a 2-week intensive drone training campaign at CEUS Huelva. The operation involved multiple daily flight cycles for defense contractor pilots and engineers testing new UAV platforms. Fuel quality, delivery reliability, and zero-downtime logistics were non-negotiable — any interruption would delay critical defense development timelines.

Rapid Mobilization & On-Site Fuel Management

Suat Fuels deployed a dedicated fuel supply solution tailored to the mission-critical nature of defense UAV testing:

  • 48-hour mobilization — Contracted, certified, and delivered first batch within 2 business days of request
  • ASTM D1655 Jet A-1 — Full specification compliance with batch certificates of analysis (CoA) provided for each delivery
  • On-site coordination — Suat logistics team worked directly with INTA ground operations to synchronize deliveries with flight schedules
  • Flexible replenishment — Daily consumption monitoring and just-in-time refueling to avoid storage constraints at the remote testing site
  • Safety & compliance — Full adherence to Spanish defense procurement protocols and INTA environmental/safety standards

✓ Key Execution Details

Suat coordinated road tanker deliveries from our Andalusia distribution network, ensuring fuel arrived within 4-hour delivery windows aligned with CEUS daily flight operations. Our team remained on standby throughout the campaign to handle any emergency top-ups or schedule changes.

The training campaign was completed on schedule with zero fuel-related delays. INTA's flight operations ran seamlessly, enabling defense contractors to validate UAV performance, pilot proficiency, and mission readiness within the planned timeframe.

Suat's ability to mobilize rapidly, maintain fuel quality under demanding field conditions, and adapt to dynamic operational requirements demonstrated our capability to support time-sensitive defense and government missions across Spain and beyond.

"Suat Fuels' responsiveness and operational discipline were exactly what we needed for this critical training cycle. Their team understood the mission stakes and delivered accordingly."
