Fastest Fighter jets in the world
According to the Saber Rattling Team the fastest fighter jets are usually interceptor like Mikoyan MIG-31 and others given down there
MiG-31
At 17,500 m (57,000 ft), the MiG-31 can achieve a top speed of 3000 km/h (1865 mph), or Mach 2.83. Which made MIG-31 one of fastest aircraft in the world.
F-15C Eagle

F-15C can fly with a top speed of Mach 2.5 (1,650 mph, 2,655 km/h) at high altitude which made F-15C Eagle second fastest aircraft.
Su-27 B
The SU-27 is a super maneuverability fighter which achieve speed of Mach 2.35 at M2 altitude
2,500 km/h (1,600 mph, 1,300 kn) / Mach 2.35 at altitude
J-20

The J-20 known as Mighty Dragon is the new development Chengdu Aerospace Corporation for the People’s Liberation Army Air Force (PLAAF). With twin WS-10B engine allows it to achieve a speed of Mach 2+ which makes J-20 one of the fastest 5th generation fighter in the world
Mach 2+ 2450 km/h (1535mph)
Mirage 2000C
The Mirage 2000 is one of the iconic fighters of Dassault Aviation France which can go at a speed of Mach 2.2 at high altitudes
2,336 km/h (1,452 mph/ Mach 2.2) at high altitude
JAS-39A Gripen
The SAAB Gripen JAS-39 single engine fighter can achieve Mach 2 speed at 10,000m altitudes.
2,460 km/h (1,530 mph, 1,330 kn) Mach 2
Euro Fighter Typhoon
The two Euro jet EJ200 engines of Euro Fighter Typhoon allow it to achieve Mach 2+ at 10,975m altitude.
2,495 km/h (1,550 mph, 1,347 kn) / Mach 2.0+ (2,495 km/h or 1,550 mph at 10,975m altitude)
F-22 Raptor

Meanwhile the famous F-22 Raptor is also at a similar speed level
Despite being a dedicated air superiority fighter, the F-22 still does not need to compete with interceptor aircraft like the MiG-25. At high altitude, the F-22A has a top speed of 2335 km/h (1450 mph).
F-16D

The nature of the F-16’s role means it doesn’t necessarily need to be the fastest jet out there. The F-16D, at high altitude, can achieve a top speed of 2142 km/h (1330 mph).
JF-17B
The Twin seated Pakistan Air force fighter can achieve Mach 2 speed at high altitude.
2,400 km/h (1,500 mph, 1,2250kn)Mach 2
