JP-5 Fuel, NATO F-44 naval aviation fuel
JP-5 fuel has the highest flash point of any standard jet fuel, engineered for carrier flight deck safety, enclosed-ship storage and Marine Corps aviation ashore.
NATO F-44
What is JP-5 fuel?
JP-5 fuel (also searched as JP5 fuel or JP-5) is a high flash point kerosene aviation fuel specified by MIL-DTL-5624. NATO codes it F-44. The defining requirement is a minimum flash point of 60°C (140°F), materially safer than JP-8 / Jet A-1 (38°C) for carrier hangars, below-deck tanks and enclosed shipboard handling.
JP-5 fuel serves carrier air wings (fighters, AEW, helicopters) and land-based squadrons that must uplift carrier-grade fuel. The military additive package (CI/LI, FSII, SDA) mirrors JP-8 for corrosion, icing and static protection.
At 15°C, JP-5 fuel density is typically 0.788-0.845 kg/L (≈ 6.6-7.1 lb per US gallon). Exact batch density is confirmed on the Certificate of Analysis shipped with every lot, a common procurement check alongside flash point.

Frequently asked questions
What is JP-5 fuel?
JP-5 fuel (JP5 / JP-5) is a high flash point kerosene aviation fuel to MIL-DTL-5624. NATO designates it F-44. It is built for carrier flight decks and enclosed-ship storage where fire safety requires a minimum 60°C flash point.
What is JP-5 fuel density?
JP-5 fuel density at 15°C is typically 0.788-0.845 kg/L. Exact batch density is reported on the Certificate of Analysis.
What is the flash point of JP-5?
Minimum 60°C (140°F) per MIL-DTL-5624, the highest of any standard jet fuel, for carrier fire safety.
JP-5 vs JP-8, what is the difference?
Flash point: 60°C vs 38°C. JP-5 fuel = carrier aviation (F-44); JP-8 fuel = land bases (F-34).
JP-5 vs JP-4?
JP-4 (F-40) is a wide-cut, more volatile legacy grade largely retired for safety. JP-5 fuel is the modern high-flash carrier kerosene; choose JP-5 for naval aviation programs.
What is F-44?
F-44 is the NATO STANAG code for JP-5 carrier-grade aviation fuel.
What is JP-5 fuel used for?
JP-5 fuel powers carrier air wings, fighters, AEW aircraft and helicopters, plus land-based squadrons that must uplift carrier-grade fuel. It is the Navy’s high-flash aviation kerosene for flight-deck and shipboard safety.
Does the navy still use JP-5?
Yes. JP-5 (NATO F-44) remains the carrier-grade aviation fuel for shipboard aviation where a ≥60°C flash point is required. Ashore, some programs uplift JP-8 / F-24; on carriers and enclosed ship storage, JP-5 is still the safety standard.
How much does 1 gallon of JP-5 weigh?
At 15°C, JP-5 fuel density ≈ 0.788-0.845 kg/L, so one US gallon weighs roughly 6.6-7.1 lb (≈3.0-3.2 kg). Exact weight depends on batch density on the CoA.
Is JP-5 the same as diesel?
No. JP-5 is a kerosene-type aviation turbine fuel. Naval ship diesels and gas turbines typically burn F-76 distillate, not JP-5. Cetane, distillation and use-cases differ.
Where can I buy JP-5 fuel?
