The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit. Transonic: 0.8 ...
The transonic speed range is that range of speeds within which the airflow over different parts of an aircraft is between subsonic and supersonic. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. [citation needed] Northrop X-4 Bantam (Mach 0.9) — Supersonic [1.2–5) 921–3,836 mph (1,482–6,173 km/h; 412 ...
Uncrewed torpedo speed claims range from 60 knots (110 km/h; 69 mph) for the British Spearfish torpedo [64] to 200 knots (370 km/h; 230 mph) for the Russian VA-111 Shkval.

The Ford Mustang Mach-E is a battery electric compact crossover SUV produced by Ford. [12] Introduced on November 17, 2019, it went on sale in December 2020 as a 2021 model. [13] [14] The Mach-E is part of the Mustang series, [15] with its name inspired by the Mach 1 variant of the first-generation Mustang. The car won the 2021 North American ...
where a 0 is 1,225 km/h (661.45 kn) (the standard speed of sound at 15 °C), M is the Mach number, P is static pressure, and P 0 is standard sea level pressure (1013.25 hPa). Combining the above with the expression for Mach number gives EAS as a function of impact pressure and static pressure (valid for subsonic flow):
