As previously reported in Tactical and Technical Trends (No. 4, p. 21) the
Axis armies are using hollow-charge ammunition. This is armor-piercing ammunition with
an explosive charge or filling and is designed to pierce armor at relatively low muzzle
velocities. The Germans consider that it achieves reasonably good armor penetration with
little loss of antipersonnel fragmentation.
The Germans are known to have at least 3 types of hollow-charge ammunition, all
caliber 75-mm and designated as follows:
7.5-cm Pz. Gr. Patr. 38 KwK,
7.5-cm Gr. 38,
7.5-cm Jgr. 38.
The first type is used in both the short- and long-barrelled 75-mm tank
guns; presumably this ammunition could be used in the new 75-mm antitank
gun (7.5-cm Pak 40) discussed in this issue in article number 4. The
second type is designed for the 75-mm light field gun 18, and the
third type for the 75-mm infantry gun.
The Italians also are reported as having developed hollow-charge ammunition. They
are known to have three types, 75/18, 75/27, and 100/17. The 75/18 is
designed for the Italian 75/18 (caliber 75-mm, length of
bore 18 calibers) gun-howitzer, the 75/27 for the standard 75-mm light
field piece, and the 100/17 for the 100-mm mountain howitzer.
The 75/18 weapon exists in two models: model 34 and 35. Model 34 is
a mountain gun; model 35, which has a more heavily constructed carriage, is
used as a field piece and a self-propelled armored
mount (see Tactical and Technical Trends, No. 6, p. 35).
