The SD 4 HL ( HL for shaped charge ) was a German shaped charge bomb for fighting tanks by aircraft during the Second World War . It was dropped from drop containers as a cluster bomb .

Data

The SD 4 HL was dropped with the dropping container 500 (AB 500), which held 74 bombs, and the AB 250, which held 40 bombs. It could penetrate the relatively thin cover armor of any tank at the time. The bomb weighed 4 kg, was 90 mm in diameter and 310 mm in length. As an explosive charge it contained 0.31 kg Hexotol 50 (a melt-castable mixture consisting of 50% Trotyl and Hexogen ), as well as the small ignition charge 34 / Np loaded with 7 grams of Nitropenta . The bomb penetrated 13 cm of armor steel at an impact angle of 60 °; In addition, its steel body was broken up into 300-400 fragments weighing more than 1 gram during the detonation, which acted against easily injured targets within a radius of 13 m from the bomb with an average fragment density of one effective fragment per m² area.

The Soviet counterpart, the PTAB , was used for the first time in the battle of the Kursk Arch . On March 5, 1944, Hitler released the SD 4 HL after it had been held back in order not to make the enemy aware of the possibility of effective anti-tank combat from the air.
