The next generation of military aircraft represents the latest evolution in aerial combat, and much of this leap forward is in stealth technology. Although modern stealth technology was first developed in the late 1970s, it has become increasingly prevalent in the fifth-generation of fighter jet aircraft. Stealth aircraft combine technologies that aim to help the aircraft avoid detection by reducing reflection, radar detection, and certain emissions such as infrared, radio frequency, and audio.

These advanced crafts have enhanced stealth capabilities, highly integrated computer systems, and superior overall performance. Famous examples of such technology include the F-22 Raptor and F-35 Lightning II, both hailing from the United States. 

To identify the most widely used stealth planes on Earth, 24/7 Wall St. reviewed the report 2023 World Air Forces from FlightGlobal, an aviation and aerospace industry website. Stealth aircraft, including uncrewed aerial vehicles, were ranked by the number of units in service in the 163 countries with data on FlightGlobal. UAV figures came from Military Factory. Supplemental data regarding the type of aircraft and notable countries that use it also came from FlightGlobal. Data on top speed came from Military Factory.

Notably, most of the aircraft on the list are fifth-generation fighter jets loaded with stealth technology that allows them to effectively evade or minimize detection by radar and other sensor systems. Other entries include the next generation of UAVs generally purposed for reconnaissance or surveillance. Stealth bombers make an appearance as well. (Also see, the 26 military aircraft of the future.)

Stealth aircraft of only three countries make the list – Russia, China, and the United States. Noticeably, not many other countries have stealth aircraft as they lack the production capabilities. However, the United States has already been shipping its F-35 Lightning II to its allies, while Russia and China are reportedly looking to sell their next generation of stealth aircraft as well.

The F-35 Lightning II is the most prevalent stealth aircraft on this list, employed by a host of countries — mainly U.S. allies. Its design integrates radar-absorbent materials and distinctive external lines commonly found in stealth technology. The aircraft’s structure is intentionally crafted to deflect incoming radar signals away from the source radar, thus lowering the radar cross-section and making it difficult for defense systems to pinpoint its actual location. Additionally, the aircraft’s thermal signature is reduced due to the internal integration of weapon systems and engine exhaust cooling technologies. (On the flip side, these are the aircraft being phased out by the U.S. military.)

Overall, the stealth features, sophisticated computer systems, and improved performance characteristics of these aircraft represent considerable strides in defense aviation technology. As modern warfare continues to evolve, the importance of incorporating stealth aircraft into air forces across the world would be paramount.
