The Original and the Most Advanced Stealth Fighters Today

stealth 1
Stealth jet fighters represent the pinnacle of technological weapons sophistication. They are an integral part of our airforce, and the airforces of developed countries around the world. These stealth fighters are at the bleeding edge of innovation, and will play major roles in future conflicts. Here are the world’s top 5 stealth fighter planes that are above and beyond anything we have seen so far!

Shenyang J-31
stealth 2
• Top speed: 1,367 mph

• First flight: October 31, 2012

• Country of origin: China

stealth 3
The Shenyang J-31 is a Chinese fighter jet that’s earned the nicknames “Gyrfalcon” and “Falcon Hawk.” It’s a twin-engine, fifth generation fighter that’s still in the process of being developed. It was designed and built by the Shenyang Aircraft Corporation.

The Sukhoi T-50
stealth 4
• Crew: one pilot

• Length: 55 feet, 5 inches

• Wingspan: 37 feet, 9 inches

stealth 5
Similar to other 5th generation fighter jets like the Sukhoi T-50, the Shenyang J-31 has twin rudders and two engines. It boasts forward-swept intake ramps with diverterless supersonic inlet bumps and trapezoid-shaped wings. The J-31 is the Chengdu J-20’s little brother, smaller and more maneuverable.

Chengdu J-20

stealth 6

• Gross weight: 70,750 lb

• Wing area: 840 sq ft

• Country of origin: China

stealth 6b
The Chengdu J-20 is a Chinese stealth jet. It’s a twin-engine, fifth-generation fighter that’s still in the prototype stage. It’s in development by Chengdu Aerospace Corporation, for use in the Chinese Air Force. Its first test flight was on January 11, 2011. Fully operational jets won’t be rolled out until 2018. Production is being stalled by some technical complications, though China is hopeful that it will extend its long-range striking power in the region.

stealth 8a
• Crew: one pilot

• Length: 66.8 feet

• Wingspan: 44.2 feet

stealth 8b
The J-20 was built with a stealth profile in mind, but it already has some critics. Some people think that the J-20’s engine nozzles may compromise its stealth and allow it to be detected by radar. One of the prototypes had WS-10G engines that were constructed with jagged-edged tiles and nozzles, which helped ameliorate the negative stealth impacts.

F-22 Raptor
stealth 9
• Top speed: 1,500 mph

• Cost: $150 million each

• Country of origin: United States

stealth 9a
Developed by Lockheed Martin, the F-22 Raptor is a twin-engine tactical fighter aircraft currently in use by the United States Air Force. It was designed to be an air superiority fighter, but is also equipped to conduct ground attack, signals intelligence and electronic warfare maneuvers. Boeing also collaborated with Lockheed Martin to construct the F-22s, contributing the wings, aft fuselages and training systems.

The F-22
stealth 10 f22
• First flight: September 7, 1997

• Number built: 195

• Crew: one

stealth 10a F22
The F-22 boasts a number of stealth properties, including a precisely engineered airframe with fixed-geometry serpentine inlets, which reduce visibility. It was also built with radar-absorbent material, and has low radio emissions, reduced infrared and acoustic signatures and even a lower visibility to the naked human eye.

F-35 Lightning II

stealth 11 f35
• Top speed: 1,200 mph

• Cost: $98-116 million

• Country of origin: United States

stealth 11a f 35
The F-35 Lightning II, developed by Lockheed Martin, is a single-engine multirole stealth fighter. It is still in development, but it’s in the final stages. Its primary role will be to conduct aerial reconnaissance, ground attack and air defense operations, and will be available in three variations. The F-35 is an evolution of the X-35, the best design from the Joint Strike Fighter program. The development of the F-35 Lightning II is the most expensive military weapons system development program in history.

stealth 12
• First flight: December 15, 2006

• Number built: 115

• Length: 50.5 feet

stealth 12a
The F-35 uses radar-absorbent materials and was designed to have a low radar cross-section. It also incorporates systems to reduce its infrared and visual signatures. Its acoustic signature, however, is problematic. The F-35 is twice as loud as the McDonnell Douglas F-15 Eagle during takeoff, and four times as loud when landing. The USAF conducted an environmental impact study and found that if they replaced the F-16s at the Tuscon International Airport with F-35s, more than twenty one times more nearby residents would be exposed to unacceptable noise levels.


1. PAK FA T-50

stealth 13
• Top speed: 1,520 mph

• Cost: $50 million

• Countries of origin: Russia, India

stealth 13a
PAK FA translates to “Prospective Airborne Complex of Frontline Aviation.” It’s a fifth-generation fighter jet currently being prototyped by Sukhoi for use by the Russian Air Force. It will be the first Russian aircraft to use stealth technology, and is intended primarily as an air superiority and attack jet. It is intended to succeed the MiG-29 and Su-27 aircraft.

stealth 14
• Crew: one pilot

• Length: 65 feet

• Wingspan: 45.8 ft

stealth 14a
Much like the F-22, the T-50 reduces its radar cross-section through the use of planform edge alignment. The edges of its wings and control surfaces are aligned in such a way as to minimally reflect radar waves. Its weapons are carried inside the airframe, and it has recessed antennae as well. Its rear portions feature radar-absorbent material, as well as its canopy.
