Which aircraft lots require the use of lox?

The use of liquid oxygen (LOX) is specifically associated with a particular range of aircraft lots in the Super Hornet fleet, which reflects design and operational requirements for these aircraft. Lots 12 and below require LOX due to the specific configurations and systems installed in those variants, which include considerations for high-altitude and high-performance capabilities that necessitate the use of LOX to ensure optimal performance and pilot safety.

In contrast, lots above this designation, particularly starting from Lot 13, often use different systems or configurations that do not require the same level of oxygen support, reflecting advancements in the design and technology that may have integrated alternative solutions. Thus, recognizing that only Lot 12 and below require LOX illustrates an understanding of the evolution of aircraft systems and the operational dependencies tied to different aircraft lots in the Super Hornet program.
