The 9 fastest piloted planes in the world

The world's fastest manned planes are nothing short of engineering marvels.

Capable of flitting through the air at multiple times the speed of sound, these planes take the pilot to the fringe of science fiction.

Although a number of these aircraft have since been retired, they continue to be the fastest manned aircraft in history.

The designs and advances achieved with these planes have also left an immense impact upon the development of the planes that succeeded them.

Here's a look at the world's nine fastest manned aircraft ever flown.

F-4 Phantom II

Maximum speed: 1,472 mph

Maximum range:1,615 miles

First flight: May 27, 1958

The supersonic F-4 Phantom II jet was originally developed just for the US Navy and officially entered into service in 1960. In the mid-1960s, the interceptor was adopted by the US Marine Corps and the US Air Force.

The F-4 carries more than 18,000 pounds of weapons, including air-to-air missiles, air-to-ground missiles, and various bombs. The primary fighter jet during the Vietnam War, the Phantom II was gradually replaced by the F-15 and the F-18 Hornet.

Convair F-106 Delta Dart

Maximum speed: 1,525 mph

Maximum range:1,800 miles

First flight: December 25, 1956

First introduced into service in 1959, the Convair F-106 was designed to intercept and destroy Soviet bombers during the Cold War. The Delta Dart carried sophisticated radar, infrared missiles, and a nuclear-tipped rocket, according to the Aerospace Museum of California.

The F-106 still holds the world record as the fastest single-engine fighter at 1,525 mph. The F-106 is considered one of the most challenging fighter jets to operate because of its heavy cockpit workload.

Mikoyan MiG-31 Foxhound

Maximum speed: 1,860 mph

Maximum range:2,050 miles

First flight: September 16, 1975

First introduced into service on May 6, 1981, the Soviet MiG-31 remains one of the fastest combat jets ever designed. Built as an interceptor aircraft, the Foxhound continues to serve in the Russian and Kazakh air forces.

Despite its age, Russia plans to keep the aircraft in service until 2030.

Mikoyan Ye-152

Maximum speed: 1,883 mph

Maximum range: 913 miles

First flight: July 10, 1959

The Ye-152 was first introduced in 1959 and was an operational interceptor derived from the Mikoyan Ye-150. The Ye-152 is best known for paving the way for the Mikoyan-Gurevich MiG-25 Foxbat.

XB-70 Valkyrie

Maximum speed: 2,056 mph

Maximum range: 4,288 miles

First flight: September 21, 1964

The XB-70 was a prototype of the never-completed US B-70 nuclear-capable strategic bomber. The bomber was intended to bomb targets while traveling at over Mach 3 at high altitudes.

Soviet missile defenses and the expansion of the role of intercontinental ballistic missile systems ultimately led to the abandonment of the B-70 program. The only two completed XB-70 prototypes were then used as test vehicles for high-speed flight.

Bell X-2 "Starbuster"

Maximum speed: 2,094 mph

First flight: September 18, 1955

The Bell X-2, which only flew for a brief span between November 1955 and September 1956, was a research aircraft jointly constructed by the Bell Aircraft Corporation, the US Air Force, and the National Advisory Committee for Aeronautics. The plane was developed to test flight between Mach 2 and 3.

On September 27, 1956, the X-2 reached its recorded maximum speed of 2,094 mph. During the flight, however, test pilot Milburn G. Apt died. He was the first man to break Mach 3.

Mikoyan-Gurevich MiG-25 Foxbat

Maximum speed: 2,170 mph

Maximum range: 1,599 miles

First flight: March 6, 1964

The Soviet MiG-25, which was first introduced in 1970, was built as a supersonic interceptor and reconnaissance aircraft. Due to the aircraft's large wings, the US assumed it was a highly maneuverable fighter. Instead, the Foxbat needed the large wings due to its weight.

The MiG-25's maximum speed of Mach 3.2 is not sustainable without causing engine damage. Its top sustainable speed is 1,920 mph (Mach 2.83).

SR-71 Blackbird

Maximum speed: 2,200 mph

Maximum range:3,682 miles

First flight: December 22, 1964

The SR-71, designed by Lockheed Martin, was a marvel of a plane. It flew at altitudes of over 80,000 feet at speeds greater than 2,000 mph. The plane, engineered for surveillance, flew for more than 30 years and was capable of outrunning antiaircraft missiles lobbed at it.

For perspective, on its retirement flight from Los Angeles to Washington, D.C., the SR-71 flew coast to coast in only 67 minutes.

X-15

Maximum speed: 4,520 mph

First flight: June 8, 1959

The world's fastest manned aircraft is the rocket-powered X-15. The X-15 flew for the first time on June 8, 1959, after successfully deployed at 45,000 feet from another aircraft. A few years later, on October 3, 1967, the X-15 pulverized all flight-speed records with a stunning 4,520 mph, or Mach 6.72, speed.

Three X-15s were made and flew a total of 199 flights before the $300 million program was retired.
