Histo
1. In 1943,a submarine development group was formed at Blankenburg/Harz and
was given the name Glieckauf. , This-group was headed. administratively by
a Dr. FISCHFR, who was a naval architect. The first project-lasaigtied to
th@ group was the design of the type No. 26, submarine, and, *hen the,-war l

extension of his work with MAN,

2. Eight days before the occupation of Blankenburg by the Americans,
on about 20 April 1915, the Glueckauf group started a systematic
paper and design burning pro ram. Theoretically,. all plans and
papers were destroyed, but two persons =saved some
of the operation instructions for the type No. 26 motor. These
persons were a Dipl. Ing. Gustav SCHROETER and Ing. WATZE.. The
Americans occupied Blankenburg until about the end of May 1915.
During this tune, they put to work a few of the Glueckauf
technicians and designers in reconstructing certain of the wartime
designs. From the end of May 1915 until the middle of July 1915,
the British occupied Blankenburg, but did not continue the policy
of employing technicians.

About the middle'of July 1945, the Soviets occupied Blankenburg.
After about 14 days., the Soviets ordered the local police to round i
up all the. remaining members of the wartime Glueckauf group. The
Soviets then requested the members to go to the USSR and work.for
them. No one volunteered. The Soviets then made everyone an offer,
who would work for them at Blankenburg. No one volunteered. They
were then escorted to the Glueckauf plant, the door was forced, the
place inspected. Many papers and designs which had not been burned
were found. The Soviets interrogated the remaining personnel as to
the identity of the remaining plans and diagrams. This occurred
early in Aupist of 194.
1., It was later learned that some time in the early if'aM of 19h5,
the Soviets;
reorganized the old Glueckauf group. From now on, this re-
organized Gluekau_f group will be referred to as the Elankenburg
group. S'TATESNT was the scientific and technical director, while
WITT was the administrative director. STATESNY got in touch with
his,old superior KTAUSEN,, who had tone to Hamburg after the and
of the war, and persuaded him to join the group. STATESNT and
? AUSEN had now changed places, and STATESNY was now KLAUSEN's
superior. This shift was probably due to the fact that STATESNY
had been on, the scene and, after helping to reorganize the group,
was made the technical and scientific director as a sort of-reward.
I KLA.USEN, bscause of
his former position, had a much better overall owledge of the
various operations of the group,as well as lof the, ai bilities"of the
members. 'KLA,USEN was deputy scientific and technical director
under STASNY and ?I,j fell naturally into his old position
as immediate overall supervisor of the project.

At the end of, this time, two Soviet naval officers
were attached to the Blankenburg group. Their
names were SLOTOPOLSKI and BRAHMANN. They
served as the official adminstrative head of the
group till the arrival of Col. ANTIPIN some time
later.

civilian clothing. Later,,in the USSR, it was
discovered he was a naval officer, as some of
the group saw him in a uniform at some social or
state function.,

(e) Thermal insulation of the dissociation and combustion
chambers. The original design called for the use of
aluminum foil, crimpled and packed into a surrounding
jacket. later the final designs utilized an asbestos
blanket. The Soviets were always taking things apart
and--putting them together, and the asbestos blanket
insulation was much easier to assemble and take down
than the aluminum foil insulation.
(f) Design and location of the auxiliary machinery to be
located outside the pressure hull engine room mock-64up.
(:L) Pumps for lubrication, fuel, etc., which normally
would be installed in a diesel auxiliary engine
room inside the pressure hull. In the Leningrad
installation, they were placed outside for convenience.
(2) Condenser water, cooler, eto., which must be placed
outside the pressure hull in an operating submarine.

(g) Design of location of all pipe lines outside the pressure
bull for eventual operational use. The Soviets made no
attempt to simplify the maze of German piping.
(h) Design of overall assembly of prototype motor, including all
pipe lines to fuel oil, water, H202,, etc.
(i) Development of dissociation chamber types. They experimented
with the design Of various shapes, etc., for dissociation
chambers. This was simply a "keep busy" project.
(j) A brief attempt to design an indirect Walter system.
This was worked on over a period of only ten days when
the Soviets-ordered all work to be dropped on this project,
and gave directions to work on Qnll the.' Darla lEtedi8.tcely
