1. On 18 April 1951 about noon, individual twin-jet aircraft
circled over the Bernau (N 53/Z 96) area at an altitude of
about 800 meters. Description of the aircraft is as follows:
Wings fitted between the nose and tail when seen from below
at a angle to the rear, wing tips squared-off, engines about
half as long as fuselages and almost as thick as the fuselage,
fuselage not pointed at tail but rounded, elevator assembly
set high, leading adges swept back. (1)
2, On 19 April., there was no flying at the Oranienburg airfield
because of wind and rainy weather. The Germendorf-Oranien-
burg railroad line had a spur track which led to the northern
edge of the field. The siding branched off, one track led
to the south and the other to the east. A fuel container,
similar to a large railroad tank car, was mounted on a brick
pedestal about 2 meters high, just north of the branch track
leading to the east. Soviet soldiers were seen in camouflaged
trenches along the road which ran on the northern edge of the
field. They checked passing civilians. Passenger cars
25X1C latter occupied by six air force
officers, and truck were seen at the entrance to
the field. 25X1 C
3, On 22 April, there was no flying between 1.0 a.m. and 4:30
p,m. except for one biplane on a local flight. The weather
was good. The following features were observed on about
30 jet bombers parked at the field; Two jet engines in the
wings, close to the fuselage, projecting more beyond trailing
edge of wings than beyond leading edge, engine tapering to
the rear, air intake and air exhaust covered with red protect-
ing caps, cockpit in front of wings elevator and rudder
assemblies similar to those of hli -15 plane, nose wheel,

Soviet star on~:`:fuselage and on the upper portion of the
rudder assembly. No antennas were seen. Some aircraft
were painted silver, others dark olive drab. High ladders
were seen leaning against several planes. (2)
4. A Dumbo radar set, about 10 meters high was located on the
eastern edge of the field, directly on the bank of the
canal. It rotated in one direction at irregular intervals. (3)
The exact course of the runways could not be determined.
A new runway was probably under construction on the western
edge of the field, since about 30 laborers were digging
there and two steam rollers were in use. (3)
6. On 21 April between 3:30 and 7 p.m. about 1.5 twin-jet aircraft
were parked at the field. The planes had a nose wheel, and
a cockpit on top of the front section of the nose? The shape
of their rudder assemblies s similar to that of the jet
fighter with swept-back wings. A dark two-digit number was
seen below the red Soviet star on the upper section of the
rudder assemblies. Some planes had a dark brown cover. The
exact number of aircraft could not be determined since the
planes were arranged in such a way as to cover the least possible
parking space.
7. Three radio installations were seen at the field. One radio
installation, a Mumbo radar set, was located in the north-
eastern corner of the field. It did not rotate during the
time of observation. Two wooden huts were west of this radio
installation. A cable, connected to the power transmission
lines at the Oranienburg-Berlin highway led to the instal-
lation. (4) The second radio installation was in the eastern
section of the field, between the canal and the runway. There
was a mast about 8 meters high from which a single antenna led
to another mast, about 6 meters high. A wire led from the
higher mast to a radio cabin. The third radio installation,
which consisted of four braced metal masts about 6 meters
high, was located south of the second installation,in the
eastern section of the field. The masts were Interconnected
by a single antenna. In the middle of the square of toasts
there was a wooden but about 2 meters high. A vertical rod
about 2 meters long protruded from the northwestern corner
of this hut. No wires were seen leading from the masts to
this rod.
9.
The westernmost section of the field was being rolled. Two
tank trucks without numbers were parked north of the
hangar. (5)
On 23 April, at least six twin-engine jet bombers flew over
Oranienburg between 7 and 11 a.m. The planes were consider-
ably slower than jet fighters with swept-back wings. The

following features were observed: Nose wheel, engines were
under the wings and projected more beyond the leading edges
than the trailing edges of the wings, plexiglass nose except
for small recess which was apparently of metal, large rudder
assemblies fuselages protrude beyond the rudder assemblies,
elevator assemblies dihedral and swept-back. (6)
10. On 24 April, six twin-engine jet bombers were parked in front
of the assembly shop at the field at about 10 a.m. Two of
the.planes were covered with gray-green tarpaulins. No numbers
could be seen on the aircraft from a distance of about 500
meters. Many conventional aircraft were parked in the area
northeast of the hangar. There was no flying.
11. A Dumbo radar set about 10 meters high was emplaced on the
northeastern edge of the field, about 30 meters west of the
canal. A factory installation located north of the field
in the triangle formed by the railroad line, the road, and the
canal was occupied by Soviet Air Force troops. Many officers
and EM were seen entering and leaving the factory.

The aircraft are probably assigned to a unit stationed in
Oranienburg. It has not been
determined whether these planes belong to a new unit or
whether the bomber regiment equipped with PE-2s aid previously
stationed in Oranienburg is being re-equipped with this new
jet aircraft type. The latter assumption is believed more
probable.
