The fastest combat jet ever built can outrun any missile fired at it from below. It’s been retired for 20 years.
How to Play: Guess if the aircraft on the right has a HIGHER or LOWER top speed than the one on the left.

Top 10 Fastest Military Aircraft
Mach number is multiples of the speed of sound. Modern fighters typically max at Mach 2-2.5; Cold War recon birds (SR-71, MiG-25) pushed Mach 3+.
| # | Name | Top Speed (Mach) | Unit |
|---|---|---|---|
| 1 | X-15 (rocket plane) | 6.70 | Mach |
| 2 | SR-71 Blackbird (USA, retired) | 3.30 | Mach |
| 3 | MiG-25 Foxbat (USSR/Russia) | 3.20 | Mach |
| 4 | XB-70 Valkyrie (USA prototype) | 3 | Mach |
| 5 | MiG-31 Foxhound (Russia) | 2.83 | Mach |
| 6 | F-15 Eagle | 2.50 | Mach |
| 7 | Su-27 Flanker | 2.35 | Mach |
| 8 | F-14 Tomcat | 2.34 | Mach |
| 9 | F-22 Raptor | 2.25 | Mach |
| 10 | MiG-29 Fulcrum | 2.25 | Mach |
Why Speeds Have Plateaued
SR-71 Blackbird (1966-1998) reached Mach 3.3 — the fastest manned aircraft ever. Its successor (replacement) has not been built.
Modern fighters trade max speed for stealth, agility, and sensor fusion. F-35 maxes at Mach 1.6 — slower than 1960s aircraft but more capable in actual combat.
Hypersonic missiles (Mach 5+) are increasingly the focus rather than aircraft speed. Russia and China deploy hypersonic weapons; the US is catching up.
Frequently Asked Questions
Fastest fighter jet ever?
SR-71 Blackbird at Mach 3.3. MiG-25 reached Mach 3.2 but burned out engines doing so.
Why are modern jets slower?
Speed is less valuable than stealth and electronics. F-35 at Mach 1.6 is more lethal than F-15 at Mach 2.5 due to sensors and radar avoidance.
Was Concorde a fighter?
No — Concorde was a supersonic passenger jet. Listed for context. Its Mach 2.04 cruise speed exceeded most fighters of its era.
Hypersonic aircraft coming?
Possibly. Lockheed’s SR-72 concept aims for Mach 6 but hasn’t been built. China and Russia have hypersonic programs.
Note: Top speeds in Mach per official military aircraft specifications.
