Sukhoi SU-22M4: Take a tour of Soviet-era fighter jet used by Poland
Many military aircraft designed and built during the Soviet era are still in operation around the world – highlighted by the Ukrainian air force in the country's war with Russia.
One fighter bomber, the Sukhoi SU-22M4, is flying with Nato's Poland and is designed to fly low to the ground at high speeds.
The successor to the SU-17, it was originally launched in 1966 and was designed to be an export model.
This would see it head to Warsaw Pact countries, a defence collective originally made up of the Soviet Union and seven other nations, as well as around the globe.
The plane is a specialist in destroying ground targets using guided and non-guided weaponry.
It is single-engined and single-seated, with supersonic speed of up to 2,305km/h.
It has eight to 10 weapon carriers capable of taking a wide range of systems, but with the aircraft all about ground attack, it's extremely limited in taking on other air opponents.
It's an elderly airframe but is still in use in countries including Syria, Iran and Vietnam.
The Polish planes have been going through a modernisation programme since 2015, which aims to keep them flying until at least 2025.
