Supersonic in the context of "Shockwave"

Deflagration (Lat: de + flagrare, 'to burn down') is subsonic combustion in which a pre-mixed flame propagates through an explosive or a mixture of fuel and oxidizer. Deflagrations in high and low explosives or fuel–oxidizer mixtures may transition to a detonation depending upon confinement and other factors. Most fires found in daily life are diffusion flames. Deflagrations with flame speeds in the range of 1 m/s differ from detonations which propagate supersonically with detonation velocities in the range of km/s.

Detonation (from Latin detonare 'to thunder down/forth') is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds about 1 km/sec and differ from deflagrations which have subsonic flame speeds about 1 m/sec. Detonation may form from an explosion of fuel-oxidizer mixture. Compared with deflagration, detonation doesn't need to have an external oxidizer. Oxidizers and fuel mix when deflagration occurs. Detonation is more destructive than deflagration. In detonation, the flame front travels through the air-fuel faster than sound; while in deflagration, the flame front travels through the air-fuel slower than sound.

Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. TNT, dynamite, and C4 are examples of high power explosives that detonate. The velocity of detonation in solid and liquid explosives is much higher than that in gaseous ones, which allows the wave system to be observed with greater detail (higher resolution).

An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when whatever is containing the expansion is broken by the pressure that builds as the matter inside tries to expand, the matter expands forcefully. An example of this is a volcanic eruption created by the expansion of magma in a magma chamber as it rises to the surface. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.

The Tupolev Tu-22M (Russian: Туполев Ту-22М; NATO reporting name: Backfire) is a supersonic, variable-sweep wing, long-range strategic and maritime strike bomber developed by the Tupolev Design Bureau in the 1960s. The bomber was reported as being designated Tu-26 by Western intelligence at one time. During the Cold War, the Tu-22M was operated by the Soviet Air Forces (VVS) in a missile carrier strategic bombing role, and by the Soviet Naval Aviation (Aviatsiya Voyenno-Morskogo Flota, AVMF) in a long-range maritime anti-shipping role.

In 2024, the Russian Air Force had 57 aircraft in service, according to the 2024 Military Balance report by International Institute for Strategic Studies. However, in 2023, Ukraine's Main Directorate of Intelligence estimated that Russia had only 27 aircraft in operable condition.

The SEPECAT Jaguar is a British-French supersonic jet attack aircraft originally used by the British Royal Air Force and the French Air Force in the close air support and nuclear strike role. As of 2025, the Jaguar remains in service with the Indian Air Force.

Originally conceived in the 1960s as a jet trainer with a light ground attack capability, the requirement for the aircraft changed to include supersonic performance, reconnaissance and tactical nuclear strike roles. The aircraft were manufactured by SEPECAT (Société Européenne de Production de l'avion Ecole de Combat et d'Appui Tactique), a joint venture between Breguet and the British Aircraft Corporation, one of the first major joint British-French military aircraft programmes. It was also later license produced by Hindustan Aeronautics Limited in India for use of the Indian Air Force. Various single and two–seater variants of the aircraft have been developed over the years, including a maritime strike version. A carrier-based variant was also planned for French Navy service, but this was cancelled in favour of the cheaper, fully French-built Dassault-Breguet Super Étendard.
