Haltermann Carless’ high‑performance fuels are engineered to meet the highest standards in defense and space applications. This expertise is rooted in decades of fuel development for sectors where precision, repeatability and operational reliability are critical.
Haltermann Carless is CAGE-code registered and our fuels are compliant with applicable NATO, DEF STAN, and U.S. MIL-DTL fuel specifications.
Haltermann Carless supports UAV programmes with high-performing kerosene and gasoline fuels, as well as reliable, compliant supply chains for long-term programmes.
Kerosene‑type UAV fuels
Kerosene-type fuels are designed for medium and large UAVs performing long-endurance ISR (Intelligence, Surveillance, Reconnaisance) and tactical support missions. Haltermann Carless kerosene-type fuels deliver high energy density for endurance-optimised UAV platforms and feature high thermal and oxidative stability with low deposit formation enabling stable combustion behaviour and predictable engine operation across variable altitude and temperature conditions. Options with high flash point enhance safety for naval, carrier-based and forward-deployed operations. Extreme temperature fuels available.

Gasoline‑type UAV fuels
Gasoline‑type fuels are optimised for small to large UAVs using 2-stroke or 4-stroke engine powered drones, where ignition quality, fast throttle response and vapour control are critical. Haltermann Carless gasoline‑type UAV fuels provide high octane numbers for maximum efficiency and performance. Anti‑vapour‑lock characteristics and tightly controlled volatility ensure stable combustion across temperature and altitude ranges. Partly and fully sustainable options support future‑oriented UAV concepts.

Haltermann Carless RP‑1‑type and advanced RP‑1+ fuels offer higher purity and tighter specification control than conventional RP‑1. High-energy density combined with high thermal and oxidative stability and low deposit formation, supports engine durability, repeatability, and predictable combustion behaviour. Controlled purity improves storability and enables clean engine operation.
Haltermann Carless fuels also support reusable engine concepts.
