This new German 88-mm antiaircraft gun has already been described in
Tactical and Technical Trends (No. 29, p. 5). The ammunition fired is HE, with
either time or percussion fuze, and APCBC;* the weights of the projectiles are
20.68 and 22.44 pounds respectively. While an estimated muzzle velocity of
3,400 f/s was reported in Tactical and Technical Trends, it now appears from
captured range tables that with HE the muzzle velocity is 3,280 f/s, with APCBC
The total length of the APCBC round is 45.63 inches and the total weight
46.2 pounds. Each round is separately packed in a metal cylinder. The German
nomenclature is "8.8-cm Pzgr. Patr.* Flak 41." The following are some of the
details of this ammunition.
Externally the projectile resembles the standard APCBC projectile for the
older 88-mm gun. It is fitted with a ballistic cap, a piercing cap and double
rotating band. The rotating bands of the specimen examined were iron, but in projectiles
for the older 88-mm gun, both iron and bimetallic bands have been encountered.
The bursting charge is small and consists of 60 grams (.13 lb) of cyclonite. A
Bd.Z*** 5127 and a tracer are fitted. The base fuze operates as follows. A fixed
igniferous detonator is situated below a striker with a compressed spring. The
striker is held off the detonator by two balls which are kept in position by a
collar located round the fuze body. The collar is kept in position by a shear wire.
Upon impact, the collar sets forward against the shear wire and breaks it, the
balls being thereby released. The striker, under the action of its spring then hits
The projectile is painted black and has a white tip. This, however, is not
a specific indication for a projectile for the Flak 41 since it is known from
documentary evidence that a similar projectile with similar markings is used in the
older 8.8-cm gun. The weight of the projectile is 10.2 kilograms (22.44 pounds).
b. Cartridge Case
The cartridge case is necked and the specimen examined was made of
brass. It carried no design number, but 8.8-cm Flak 41 was stamped on the base.
It had the following dimensions:
|Overall length|| ||33.66 in|
|Length from base to shoulder||29.33 in|
|Length from shoulder to mouth|| 4.33 in|
|Diameter of rim|| 4.72 in|
|Diameter above rim|| 4.33 in|
|Diameter at shoulder|| 3.98 in|
|Diameter at mouth|| 3.50 in|
An electric primer is fitted. The propellant consists of 11.91 pounds of
tubular flashless propellant. The sticks have the following dimensions:
|| 29.13 in|
|| .189 in|
|| .059 in|
An igniter containing the usual German igniter powder is fitted.
