a new aiming device, the AZP-47 (Avtomaticheskaya Zenitnaya
Pritsel - Automatic AAA sight, model 1947), previously used
only in the USSR, had been brought into Germany.
it is far better than the PUAZO-3 (Pribor Upravleniya Artileriskym
Zenitmym Ognyom - AAA Director) or the AZP-39 (Automatic AAA sight,
model 1939) in that the controls are arranged for more expeditious
handling and the gunner can make slight corrections by Observing
the shellbursts.
The speed computer, distance computer and computer of angle
of dive and pitch are the automatic features of the AZP-470
The speed computer is changed to compute data on airplane
speed up to 100 km an hour, the AZP-39 could not compute data
on planes abuve 500-600 km an hour. The AZP-47 enables the
gunner himself to make adjustments for elevation and de-
flection, thus eliminating the work of a gun crew man who
worked on deflection adjustment when the AZP-39 is used.

The AZP-47 is a direct fire system and is not director con-,
'trolled. The sight itself computes all data by feeding them in-
t6 the computers for speed, distance, and angle of pitch
and dive.
Azp-47 consists of a collimator with two OC magnifying lenses

Filters (dark colored glass) are used to compensate for vary-
ing conditions of light.
How are leads accomplished? A mechanism geared to the sight
or estimated by observation and through the use of reticles

Lead is computed automatically by the sight by a mechanism
geared to the sight.
tn AAA Gun
(A) The new gun has a much longer barrel than the present 57.rmm
AT gun and is equipped with a muzzle brake.
(b) Fixed on top of the barrel is a 12.7-mm AA MG which is
synchronized to firS upon the same target as the gun. It
can be fired independently, or, simultaneously with the 57-mm
AA gun,
,Only one gunner (sighting device operator) Is required for
the gun and there is only a single Seat for a gunner, whereas
?present AA guns require two gunners and have two seats for them.
The mount for the gun is approximately the same as that of the
37-mm AA guns, model 1939.

from the horizontal is 85 degrees and the maximum depression
from the bbrizontal is 10 degrees.

is sufficient for AA purpowes, therefore larger caliber AA
guns are not necessary. Further, speed, all iMportant in AA
