The ground attack aircraft listed here are military aircraft used to attack targets on the ground with greater speed and a smaller radar cross section than strategic bombers.
[1] Historically, attack aircraft were used for their higher precision compared to strategic bombers when delivering unguided munitions.
Modern attack aircraft may be expected to function in high threat environments where enemy air defences preclude the use of strategic bombers.
There are bound to be some overlap in the role and design between categories and some multirole combat aircraft appear in more than one list.
Fighters, fighter-bombers, and even trainers have also often been used in the role of attack aircraft.
