The Pratt & Whitney J58 (JT11D-20) turbojet aero engine, which had a specific fuel requirement; namely JP-7 turbine fuel.. Turbine Fuel Low Volatility JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219 [1]) is a specialized type of jet fuel developed at Pratt and Whitney by master chemist Clarence Brown CB Eichman in 1955 for the Central Intelligence Agency ...
As of 2021, the J58 is the only known aircraft engine designed to operate continuously at maximum afterburning at high Mach number cruise. [12] [26] J58 experience was used extensively in the JTF17 engine proposal for a Mach 2.7 SST, due to significant flight time at Mach 2.7 and above. It was also used for subsequent engines developed by Pratt ...
SJ61 (JP-7/ingested air) A dual-mode ramjet/scramjet engine flown on the Boeing X-51 hypersonic demonstration vehicle. J-2X (LH2/LOX) Previously developed to be used on the Earth Departure Stage for the Block II of the Space Launch System, though the EDS was later replaced by the Exploration Upper Stage using 4 RL10 engines.
It was similar to JP-5 but with a lower freezing point and improved thermal oxidative stability. When the XB-70 program was cancelled, the JP-6 specification, MIL-J-25656, was also cancelled. [37] JP-7 was developed for the Pratt & Whitney J58 afterburning turbojet engines used in the Lockheed SR-71 Blackbird for sustained flight at Mach 3+.
SJ61 (JP-7/ingested air) – A dual-mode ramjet/scramjet engine flown on the Boeing X-51 hypersonic demonstration vehicle. AJ10 (Aerozine 50/N 2 O 4) – Second stage engine for the Delta II, used as the Orbital Maneuvering System (OMS) engine for the Space Shuttle, and the main engine for the European Orion Service Module.

The engine was produced from 1951 to 1965 with a total of 21,170 built. Many J57 models shipped since 1954 contained 7-15% of titanium, by dry weight. Commercially pure titanium was used in the inlet case and low-pressure compressor case, whereas the low-pressure rotor assembly was made up of 6Al-4V titanium alloy blades, discs and disc spacers ...
