The attached sets of six photographs of the Type 27 twin-jet planes which
have recently arrived in the Russian Zone of Germany are sent you for
retention.
2. The photographs were taken at Oranienburg Airfield
25X1 as the planes were taking off. They were taken without a
telescopic lens.
3. The planes are two types. One type (see photos 3 to 6) has a plexiglass
nose; a bulge under the fuselage, just behind the nosewheel housing and in
line with the air intakes of the eges; and a tail gun position. The
other type (see photos 1 and 2) has a solid nose, which appears to be more
pointed. It is apparently fitted with two cockpits and a tail gunner's
25X1
position, although weapons are not visible, and has no bulge under the fuselage.
This type is possibly a trainer.
Although the type 27 allegedly has an NENE engine, it is believed that this
plane is equipped with an advanced version of the JUA'R) 004. Since the end of
1947, the JUNG engine has been manufactured in mass production in UFA-Chernikovka,
and possibly also in other engine plants such as Rybinsk No. 26. The JUMO
engine has only been used in Yak-15s to date. If the JUNG 004 engine is being
used in this new type aircraft, the take-off power of the two engines will have
a thrust of 3,000 kg. If the JUNG 004 H is used, the thrust will be 3,600 kg.
It is not known whether the latter type engine has been in mass production during
recent years.
5. The overall configuration of the plane seems to have some German constructional
features. The chief designer of the Heinkel Plant, Siegfried Guenther, who
works in Kimry, is believed to have assisted in the construction of the new type
plane. The suspension of the nose wheel and the landing gear resemble the twin-
engine He-219. The swept back elevator assembly, though fitted with straight
fins, is also considered to be a mixture of Soviet and German designs. It is
believed that when the wheels of the main landing gear are retracted they turn
90 degrees.
6. The purpose of the bulge or blister under the fuselage behind the nose wheel is
not clear. This blister may be used as an additional entrance hatch for the crew,
or as a housing for photographic equipment or radar. The rod seen at the rear

of the underside of the fuselage may be either a dipole or the guide rod for
a trailing aerial.
7. The two-sectional bomb-bay door seen on photograph 1+ leads to the conclusion
that bombs weighing up to 1,000 kg can be taken up. A 2,000 pound bomb, com-
pletely assembled, required a bomb-bay at least 8.5 feet long. The bomb-bay
of this aircraft is not more than eight feet long. It is possible that this
aircraft will carry a total bomb load of 2,000 pounds, i.e.,
2 - 1,000 pound bombs
4- 500
8 - 250 n a
10 - 100
If this aircraft is to serve as a light or medium bomber, the most common
load would be 100=pound bombs (fragmentation for front line action) and the
weight of the individual bomb would not exceed the 500-pound class.
8. In the nose there are possibly two fixed weapons. (See photographs 4 and 5.)
It is not known whether an additional flexible weapon is also fitted in the
c5ckpit.. The tail gunner's station, fitted with two weapons, indicates that
the guns are remote-controlled by the gunner. The caliber of the guns is
unknown.

4. Altaough tjs type 27 allegedly has an lM engine, it is believed that this

engine has only been used in 7ak-15s to data. If the JIJIG 004 engine in being
