Compare vehicles
Two or three aircraft or launch vehicles side by side. Each kind is compared only with its own, since their published figures describe different things.

- No scoring
- No ranking and no winner.
- Gaps stay visible
- A missing value reads “Not published”, never zero.

All to one scale. Outlines traced from U.S. government drawings, public domain. Every source is listed on the credits page.

PerformanceSpeed, range and ceiling.
| Characteristic | SR-71 Blackbird | F-22 Raptor | B-2 Spirit |
|---|---|---|---|
SpeedSpeed: what this measuresIn the simplest model, maximum speed is where the engines' thrust just balances drag at a given altitude. A structural, heating or engine temperature limit can cap it first. General aerospace background, not an ORBIX calculation. | Mach 3+ Published minimum | Mach 2 Approximate public value | Mach 0.95 Published maximum |
RangeRange: what this measuresRange follows from usable fuel, engine efficiency and lift-to-drag ratio over the mission. The published figures use different bases: the F-15 and F-22 figures are ferry ranges with external fuel tanks, the F-35 figure is on internal fuel, the B-2 figure is unrefueled, and the SR-71 source gives no basis. Each cell names the basis its source gives. Read them as different measures, not one scale. General aerospace background, not an ORBIX calculation. | 2,900+ mi Published minimum | 1,850+ mi Published minimum, ferry range with two external wing fuel tanks | 6,000 nmi Approximate public value, unrefueled range |
CeilingCeiling: what this measuresService ceiling is the altitude where the best climb rate drops to 100 feet per minute. Thinner air cuts both lift and engine thrust as altitude rises, until the aircraft has almost no excess power left to climb.
