This weapon was introduced in 1941 to replace the 37-mm antitank gun. It
is one of the most effective German antitank guns at present in service. The
following sketch illustrates this gun.
|GERMAN 50-mm ANTITANK GUN|
The barrel is of monobloc, loose-barrel construction, and is fitted with a muzzle brake.
The carriage is of the split-trail type, and is carried on solid rubber
tires 31 1/2 inches in diameter. There is a third detachable
wheel to increase the speed of bringing the gun into action.
The shield consists of two 4-mm sheets of armor plate spaced about 1 inch
apart. The left side of the shield has a sighting port.
The gun is normally towed by a half-track. There is also a self-propelled
type. Recently, the gun, without a muzzle brake and electrically fired instead
of by percussion, has been mounted in the latest type of Mark III tank.
The gun fires AP shell, and AP 40 shot. The latter is a light shot with
a ballistic cap and a tungsten carbide core, which has a good armor-piercing
performance at ranges under 500 yards. The following table gives the complete
data on the three types of ammunition.
|| Fuze ||
|AP tracer shell||9 lbs 3 oz||21.4 in||4 lbs 9 oz||Base||Projectile black|
|HE shell||7 lbs 3 oz||23.7 in||3 lbs 15 oz||Nose||Projectile dark green|
|AP 40 shot||-----||-----||2.025 lbs||-----||Projectile black|
The following figures show the penetration of the two different types of armor-piercing shells.
(a) AP shell:
60-mm (2.36-in) homogeneous plate at 250 yards at 20°;
60-mm (2.36-in) homogeneous plate at 1,300 yards at normal.
The above figures are probably conservative, and were deduced from trials with a limited
supply of ammunition.
(b) AP 40 shot:
90-mm (3.54-in) homogeneous plate at 330 yards at 20°;
64-mm (2.54-in) homogeneous plate at 440 yards at 20°.
The above figures are unconfirmed.
