The major North-American aircraft factory, builder of the famous "Sabre F-86", "Mustang P-51" and others, also made engines.

-Especially rocket engines such as the XLR41-NA-1 (with the inside designation NA-704-Mark II). As well as the XLR43-NA-1 (NA-704-Mark III). They were manufactured before the 1950's. Data has been kept confidential.

From Appendix 6: The V-2 engine that was built in North America was made by North American Inc. (Builder of famous airplanes like the Mustang, Sabre and X-15).

-Other information talks about the intervention of General Electric (GE) in manufacturing.

-What is certain, is that the one shown in the illustration and exposed at the NASM is made by NAA.

-Although it is explained that it was made between 1947 and 1948 but destined for the Navaho missile project.

-They made six rocket motor prototypes to gain experience although they were never started.

"NAA engine based on that of the V-2"

-Observing carefully, we see clear differences in the upper accessories, a steam generator for the feed pump turbine and below, each inlet to the nozzle is divided into three branches instead of one in the original engine.

-The bench is also different, possibly because of Navaho.

-As mentioned in the main text, this brand made engines, especially rockets.

A North American XLR43-NA-5 is seen in the Atlas A first-stage center base in the picture below

-As we can see, the motor is pivotable, which facilitates the direction of the missile.

-Also in the early 1950's North American, a builder of memorable airplanes, made mixed power plants: the XP-81 should use the GE TG-100 turbines in the bow and the I-40 in the tail.

“The XP-81”

-Due to the delay in the delivery of the TG-100 engine, the first tests were made with a Packard-Merlin V-1650 engine. Even the entire front of this plane was that of the P-51 Mustang.

From Appendix 9: (see Rocketdyne) Attributed rocket engines:
-LR-42 (XLR-42-NA-1)
-NA-704 Mark II
-NA-704 Mark III

“NA-704 Mark III”

-LR-41 (XLR-41-NA-1)
-XLR-43-NA-1
-XLR-83-NA-1

From Appendix 10: There was a Nuclear Engine Project led by Rockwell Space Div. At Marshall Space Flight Center.
