The firing order is the same as the other AJ-V8 engines although the cylinder numbering is different (AJ37 = 1-5-4-2-6-3-7-8 vs. AJ26 = 1-2-7-3-4-5-6-8). The engine is assembled by hand at the AM facility in Cologne, Germany, which also builds the V12 for the DB9 and Vanquish. The cylinder block, cylinder heads, crankshaft, connecting rods ...
The AJ26 engine used for Antares is based on a Russian NK-33 rocket engine designed and manufactured in the early 1970s in support of the failed Russian N-1 moon program. Aerojet-Rocketdyne modifies the NK-33 configuration for use on U.S. launch vehicles. For Antares, the AJ26 also includes several operational variations from the NK-33 ...
AJ26 is a rocket engine used by Orbital Sciences Corporation for its commercial cargo missions to the International Space Station. NASA conducted a hotfire test of AJ26 engine E-15 at Stennis Space Center on Jan. 17, 2014, and cleared it for shipment to Wallops Flight Facility.

Once flight acceptance is achieved, the engine will power the first stage of Orbital's Taurus II space launch vehicle on commercial cargo missions to the International Space Station.
Aerojet's AJ26 engine is an oxidizer-rich, staged-combustion LO2/Kerosene engine that achieves very high performance in a lightweight compact package. Based on the NK-33 engine originally ...
The AJ26 engine used in the testing was removed from the E-1 stand on Jan. 24, and will be returned to Aerojet in Sacramento, Calif. to be refurbished and used on an upcoming Taurus II mission. The same day the engine was removed, the first flight engine was installed to begin regularly planned "acceptance testing" at Stennis. The AJ26 ...
