Speed has always been a headline spec for military aircraft, and Mach 2 marks a clear threshold between fast and exceptional. This list spans Cold War experiments, interceptors and fighters, and each speed is taken from a published source. Here are ten jets that cross that line.

1. Lockheed SR-71 Blackbird: The Benchmark Blackbird
Jalopnik’s fastest military aircraft ranking lists the Lockheed SR-71 Blackbird at a top speed of Mach 3.3, around 2,500 mph, and says it still holds the record for fastest jet-powered military aircraft. One SR-71 averaged 2,124 mph flying from Los Angeles to Washington in 1990.
Every other jet here sits below that mark, which makes the Blackbird the yardstick for the whole category. The figures are as the source states them, and peak speeds for aircraft like this depend on altitude and configuration. Readers comparing the whole list should note that the sources differ in age and method, so small gaps between jets say little.
2. MiG-25 Foxbat: Fast but Fragile
The Soviet MiG-25 Foxbat interceptor had an operational top speed of Mach 2.83, according to Jalopnik’s list of speed record holders. The same article says the jet could reach Mach 3.2, but only at the risk of damaging its engines.
That gap between a safe operating speed and an absolute peak is a useful reminder when comparing top-speed claims. A number reached once, with consequences, is a different thing from a speed a pilot could fly routinely. The Soviet entries in particular show how a high ceiling on speed shaped interceptor design during the Cold War era.
3. XB-70 Valkyrie: Only Two Built
Just two XB-70 Valkyrie bombers were built, and Jalopnik gives the type a maximum speed of Mach 3.1, or 2,056 mph, in its ranking of record-setting aircraft. That puts a very small fleet near the top of the speed charts.
The Valkyrie shows that speed alone did not guarantee a production run. The figure is as stated by the cited source and depends on altitude and configuration, so it is best read as a published maximum. A single-source figure like this one is best treated as a reference point for comparison, not a performance guarantee.
4. MiG-31 Foxhound: Interceptor Still Flying
Jalopnik’s entry on the Foxhound says the Mikoyan MiG-31 has been in service since 1981, with about 500 built, and lists a speed of Mach 2.83 from two D-30F6 engines.
Few aircraft on any speed list combine a Mach 2.83 rating with a production run that large and a service record dating to 1981. The listed speed is as stated by the source and varies with altitude and configuration, as with every jet here. Placing it beside the Mach 3 class above shows how large the gap is between merely supersonic and truly extreme speed.
5. Sukhoi Su-27: Flanker Family Patriarch
Live Science cites a maximum supersonic speed of Mach 2.35, or 1,550 mph, for the Sukhoi Su-27 Flanker in its guide to fast military airplanes. That is a lower figure than the Soviet interceptors above it, yet it still clears the Mach 2 line comfortably.
For readers, the Su-27 is a reminder that agile fighters sit in this club too, not only purpose-built speed machines. The number is the cited source’s, and real-world performance depends on altitude and configuration. Used as a comparison point, the number helps explain why the Flanker is often grouped with the fastest fighters of its era.
6. F-111 Aardvark: The Swing-Wing Aardvark
Live Science says the General Dynamics F-111 Aardvark was able to fly at Mach 2.5, or 1,650 mph, in its roundup of military aircraft speeds.
The Aardvark matters because a strike aircraft, not a pure interceptor, reached this speed class. As with the other entries, the speed is as stated by the cited source and depends on altitude and configuration. Readers should treat the figure as one source’s claim for a particular flight condition, not a universal rating, and as a rough guide to the class.
7. F-15 Eagle: Eagle Above Mach 2.5
Live Science describes the F-15 Eagle as capable of flying at speeds greater than Mach 2.5, or 1,650 mph, in its article on speedy warplanes. The phrasing is open-ended, so the source gives a floor rather than a precise maximum.
That wording matters when comparing entries: greater than Mach 2.5 is not the same as a measured record. The F-15 earns its place as a widely recognized fighter, with a speed as stated by the source and subject to altitude and configuration. Next to the F-111 above, it illustrates how long the Mach 2.5 class has been a fixture of air force inventories.
8. F-22 Raptor: Raptor at the Line
A 2001 Aerospaceweb table lists the F-22 Raptor at Mach 2.0, or 1,355 mph, at 30,000 feet, per its fighter speed comparison. It is the lowest figure on this list, sitting right on the Mach 2 line.
The age of that table is worth noting, since it predates much of the Raptor’s service life. The altitude is part of the published number, and the speed is as stated by the source rather than a current official specification. Even at the bottom of this list, a jet at this speed is flying at twice the speed of sound.
9. F-16 Fighting Falcon: Mach 2.05 in Clean Trim
Aerospaceweb’s 2001 aircraft speed table lists the F-16 Fighting Falcon at Mach 2.05, or 1,350 mph, at 40,000 feet in a clean configuration. Clean means without external stores, a detail that appears in the published figure.
A loaded F-16 would not necessarily match that number, so the qualifier carries real weight. The speed is as stated by the cited source and depends on altitude and configuration, like the other entries. Because the table carries a date, anyone using the number should check it against current official data.
10. F-104 Starfighter: Museum-Backed Mach 2
The Smithsonian National Air and Space Museum refers to the Lockheed F-104 Starfighter as a Mach 2 interceptor in its Cold War speed feature. The source gives the class of performance rather than a precise figure.
That makes the F-104 the loosest entry numerically, but a respected museum describing it at Mach 2 justifies its place. The speed is as stated by the cited source and depends on altitude and configuration. Readers should note the source offers a qualitative description, so no exact top speed can be quoted for this aircraft.
