PTAB (Russian ПТАБ, short for Противотанковая Авиабомба, "Antitank Aviation Bomb") was a Soviet World War II high-explosive anti-tank (HEAT) shaped charge bomb.
The Ilyushin Il-2 ground attack aircraft could carry 280 PTAB bombs directly on the bomb-bay folds, or 4x48 in four cassettes.
Introduced in 1943, PTABs were widely deployed from Il-2s,[1] and due to the bomb's very low weight, from Yakovlev Yak-9 fighters, specifically from the internal weapon bay in the Yak-9B (fighter-bomber) modification.
[2] During the 2022 Russian invasion of Ukraine, rapid technology development occurred to iterate on design of racing drones into a type of FPV loitering munition.
Aimed a very low-cost and high production volume, the heavy-duty version of the Escadrone attack drone was modified to carry a 2 kg (4.4 lb) PTAB 2.5 anti-tank bomb.
