After developing jet engines, the Great Tang Empire continuously invested technical efforts in directions such as turbojets and turbofans, developing various types of jet engines. These engines, the technologies of the future, have promising prospects not only in military use but also in civilian applications.
This is a form of technological accumulation, considered a necessary preliminary investment. With the technology of many jet engines available, more models of aircraft are poised to emerge.
The Air Force is a major user of engines, and their constraints are relatively minimal: although the Navy also eagerly anticipates jet aircraft, they indeed do not yet possess the necessary conditions to equip jet engines.
The Navy's aircraft carriers do not yet have retrofit catapult systems, so the 10 in-service carriers can only utilize propeller planes.
