In 1963, the Lockheed A-12 (code-named “Archangel”) became America’s first supersonic stealth plane. Incredibly fast, much faster than today’s sixth-generation stealth bomber, the A-12 could reach speeds of over 2,000 miles per hour. Despite its speed and innovation, it was retired soon after it was designed with the even faster SR-71 Blackbird. Today’s modern stealth planes don’t reach the speeds of the previous models mainly because they prioritize stealth over speed. Also, faster flying requires more fuel. But we’re also in the age of innovation. Countries across the globe are working to improve their stealth aircraft fleets, both with more advanced technology and new iterations of previous aircraft. For example, India may soon be prepared to get its first fifth-generation fighter jets. Israel has reported safety issues with the components of its F-35 fighter jets which might necessitate more development. As we look to the future, anticipate the onset of new-generation stealth fighters that will transform the state of warfare as we know it. (How much firepower can a stealth bomber carry?)

But for now, what stealth planes are global militaries flying? To identify the oldest and newest stealth planes in world militaries (retired, in use, and on order), 24/7 Wall St. reviewed the 2025 World Air Forces directory from Flight Global, an aviation and aerospace industry website, as well as other sources such as Military.com, military websites, and Air & Space Forces Magazine. We ordered the aircraft in chronological order from the earliest year first used to the latest. We added data from Military Factory on the type of aircraft, top speed, manufacturer, and armament. Data on notable countries that operate these aircraft came from FlightGlobal.
This article was updated on April 14, 2025 to highlight updated Flight Global data, as well as advances in stealth technology in various countries.
Why We’re Discussing Stealth Aircraft
Covert air operations began in World War I with militaries attempting to reduce the visibility or sound of their aircraft. Technology in this regard has made leaps and bounds since the First World War. Companies that manufacture these jets for the military, like Lockheed Martin (NYSE:LMT), make billions in sales every year, and it’s worth understanding how these companies operate if you’re considering investing in them. As conflict breaks out across the globe — and as the U.S. uses its aircraft to project power — knowing which countries have which stealth aircraft gives you an idea of what might happen, and who might win, should war be on the horizon.
These are stealth aircraft from the oldest to the most cutting-edge:
1. A-12 Archangel
- Top speed: 2,212 mph
- Countries that use this aircraft: United States
- Year first used: 1962
The A-12 Archangel, also known as the Lockheed A-12, is a retired high-altitude reconnaissance aircraft designed for the Central Intelligence Agency (CIA). First officially (and unofficially) flown in 1962, the A-12 Archangel was used more heavily in efforts starting the year after. The A-12 Archangel served as a stealth aircraft that allowed the CIA to effectively spy on the Soviet Union. Given the purpose of this aircraft, there were no weapons onboard.
2. SR-71 Blackbird
- Maximum speed: 2,274 mph
- Countries that use this aircraft: United States
- Year first used: 1964
Developed by Lockheed, the SR-71 Blackbird is a long-range strategic reconnaissance aircraft. The aircraft can hit speeds as fast as Mach 3.3, or three times as fast as the speed of sound. This makes the SR-71 Blackbird the world’s fastest and highest flying operational aircraft. Though the aircraft has no weapons onboard, it still remained effective in gathering intelligence in combat areas. The plane’s high operational costs are one of the reasons it was eventually retired in 1999.
3. AQM-91 Firefly

- Maximum speed: 505 mph
- Countries that use this aircraft: United States
- Year first used: 1968
The AQM-91 Firefly is an unmanned reconnaissance drone that was developed for use by the CIA and U.S. Air Force. Designed by Ryan Aeronautical and Teledyne-Ryan in 1968, this drone had an operational altitude of 78,000 feet and contained no weapons. The goal of the AQM-91 was to perform reconnaissance throughout the Vietnam War, especially around China. However, the drone never actually became operational. Its design has, however, inspired future stealth aircraft.
4. F-117 Nighthawk

- Maximum speed: 684 mph
- Countries that use this aircraft: United States
- Year first used: 1981
The F-117 Nighthawk is a stealth aircraft designed by Lockheed for attacking enemies and locations without ever being caught. It saw combat during Operation Just Cause in 1989 and Operation Desert Shield/Storm in 1990-1991. Although the F-117A has been officially retired, the U.S. Air Force still flies five F-117As, mostly as training aircraft. Because they were used as a weapon, these aircraft have laser-guided bombs, drop bombs, Maverick missiles, Sidewinder missiles, and HARM anti-radiation missiles.
5. B-2 Spirit

- Maximum speed: 628 mph
- Countries that use this aircraft: United States
- Year first used: 1997
The B-2 Spirit is a Northrop Grumman design. Despite being a heavy bomber plane, it’s made for strategic and stealthy attacks. This aircraft is absolutely loaded with weapons like free-fall nuclear bombs, drop bombs, joint direct attack munitions, air-to-surface missiles, and cruise missiles. Right now, the U.S. Air Force currently has 18 B-2 Spirit aircraft in active service. However, the B-2 Spirit is scheduled to be removed from service starting in 2032, mostly due to its high cost of repair.
6. Shenyang J-11B

- Maximum speed: 1,553 mph
- Countries that use this aircraft: China
- Year first used: 1998
While most of the aircraft you’ve seen so far were designed for the United States, China also holds its fair share of stealth aircraft. The Shenyang J-11B aircraft was created by Shenyang Aircraft Corporation and the Aviation Industry Corporation of China. This stealth plane also doubles as a 4th generation air superiority fighter with 30mm GSh-30-1 internal cannon, air-to-air missiles, air-to-surface missiles, air-to-surface missiles, laser-guided bombs, conventional drop bombs, cluster bombs, and rocket pods. Between the J-11, J-16 (which you’ll see later), J-30, and J-35, China currently has 319 of these aircraft in active service.
7. F-22 Raptor

- Maximum speed: 1,500 mph
- Countries that use this aircraft: United States
- Year first used: 2005
Lockheed Martin’s F-22 Raptor first took flight in 1997 before being introduced into military service in 2005. The F-22 Raptor, an effort from both Lockheed Martin and Boeing, is a fifth-generation air dominance fighter. Its speed, stealth, agility, and avionics make this plane a formidable opponent — and the weapons only supplement that: a 20mm internal automatic canon, Sidewinder missiles, AMRAAM missiles, joint direct attack munitions, air-launched cruise missiles, and guided bombs. It’s no surprise that the F-22 Raptor remains a key part of the U.S. fleet, with 178 active aircraft.
8. RQ-170 Sentinel

- Maximum speed: 590 mph
- Countries that use this aircraft: United States
- Year first used: 2007
This aircraft, nicknamed the “Wraith,” was made for the United States in 2007 by Lockheed Martin. It doesn’t go very fast, but considering it’s an unmanned vehicle, it does well. There’s not much known about this aircraft. The U.S. Air Force was believed to have 20 to 30 of these aircraft, but there seems to be a lot of uncertainty. Although the RQ-170 Sentinel is not listed in the World Air Forces directory, some sources say that these aircraft were deployed as recently as 2021.
9. Shenyang J-16 (Red Eagle)

- Maximum speed: 1,534 mph
- Countries that use this aircraft: China
- Year first used: 2013
The Shenyang J-16, also known as the Red Eagle, is another Chinese stealth aircraft. This one is more modern, built in 2013, and can handle speeds above 1,500 miles per hour. This all-weather fourth-generation strike fighter aircraft features weapons like anti-radiation missiles, rocket pods, anti-ship missiles, laser-guided munitions, drop bombs, internal cannons, and several types of air missiles. It was made by Shenyang Aircraft Corporation and Aviation Industry Corporation of China. As stated earlier, there are 319 active J-11/16/Su-27/30/35 planes in service.
10. RQ-180

- Maximum speed: 590 mph
- Countries that use this aircraft: United States
- Year first used: 2015
The RQ-180 is a United States aircraft made by Northrop Grumman. This unmanned aerial vehicle is designed for stealth and reconnaissance — and is SO good that many people wonder if the RQ-180 is even real. To this day, the aircraft (sometimes called the White Bat), has only been officially photographed a few times. As far as we know, the RQ-180 has no weapons. There is some evidence that the RQ-180 has been used in active service, but this information is being kept heavily under wraps.
11. WZ-10 Cloud Shadow

- Maximum speed: 390 mph
- Countries that use this aircraft: China
- Year first used: 2016
Cloud Shadow is a Chinese aircraft made by the Chengdu Aircraft Industry Group. When it comes to speed, the WZ-10 doesn’t have it; this is a rather slow unmanned aerial vehicle, with a top speed below 400 miles per hour. However, unlike many unmanned aerial vehicles on this list, it includes air-to-surface missiles, light cruise missiles, and precision-guided bombs. Over the past year, Japan has intercepted WZ-10 aircraft over the East China Sea, and the WZ-10 was also tracked in the South China Sea near Vietnam.
12. F-35 Lightning II

- Maximum speed: 1,229 mph
- Countries that use this aircraft: Canada, Czech Republic, Denmark, Germany, Israel, Italy, Japan, Poland, United Arab Emirates, United Kingdom, United States

It’s a fifth-generation multirole stealth aircraft with internal cannons, air-to-air missiles, air-to-surface missiles, anti-radiation missiles, laser-guided bombs, and conventional drop bombs. This all-weather stealth fighter is considered one of China’s most advanced aircraft.
14. GJ-11 Gongji

- Maximum speed: 621 mph
- Countries that use this aircraft: China
- Year first used: 2019
The GJ-11 Gongji is a plane by the State Factories for China in 2019. This unmanned combat aerial vehicle goes at a fairly impressive speed of over 600 miles per hour. It also has a few weapons, including laser-guided bombs, drop bombs, and air-to-surface missiles. Some military strategists believe that China could deploy these aircraft in an unexpected way that could be hard to combat from other forces.
15. Sukhoi Su-57 Felon

- Maximum speed: 1,616 mph
- Countries that use this aircraft: Russia
- Year first used: 2019
The Sukhoi Su-57 Felon is a Russian aircraft made by Sukhoi OKB and the United Aircraft Corporation.
