Attack aircraft have long been one of the main types of fighter jets, but it seems they are a dying breed and will disappear in the coming years. Since the 1960s, the world has seen only two types of dedicated attack aircraft widely introduced – the Fairchild Republic A-10 Thunderbolt II (in phased retirement) and the Soviet Sukhoi Su-25 Frogfoot (actively fighting almost every day). However, both aircraft are out of production, and there are no directly planned replacements.
