JP-5, or JP5 (for "Jet Propellant") is a jet fuel that weighs 6.8 pounds per gallon and has a high flash point (min. convert|60|°C|°F|sigfig=2). [ [ Characteristics of Fuels] Marine Corps Schools Detachment - Ft. Leonard Wood] It was developed in 1952 for use in aircraft stationed aboard aircraft carriers where the risk from fire is particularly great. JP-5 remains the primary jet fuel for most navies. Its NATO code is F-44. It is also called AVCAT. It is specified by MIL-DTL-5624 U (TURBINE FUEL, AVIATION, GRADES JP-4 AND JP-5), last issued on 2004, and meets the British Specification DEF STAN 91-86 AVCAT/FSII (formerly DERD 2452).

The JP-4 and JP-5 fuels, covered by the MIL-DTL-5624 U Specification, are intended for use in aircraft turbine engines. These fuels require military unique additives that are necessary in military weapon systems. This requirement is unique to military aircraft, engine designs, and missions.

Additionally, JP-5 is a military unique fuel because it must have a flash point substantially higher than commercial aviation turbine fuels. It is stored in large quantities on aircraft carriers and other vessels. The flash point is for safety in these military unique applications.

Freezing point of JP-5 is −46 °C and the flash point > 60°C. It does not contain antistatic agents. It is a yellow liquid, based on kerosene.

Other names for JP-5 are NCI-C54784, Fuel oil no. 5, Residual oil no. 5.

JP-5 is a complex mixture of hydrocarbons, containing alkanes, naphthenes, and aromatic hydrocarbons.
