The exact course could not be observed. On 25 January 1955, no special activity was observed in the radar ^tation. Six soldiers were seen near the group of motor vehicles and 4 soldiers near the Kniferest-type set. 4. Perleberg radar station. On 8 March 1955, the following radar sets were observed in the installation: 1 Token 1 Kniferest 1 Fishnett 4 radio trucks. Three of the 4alradio trucks had a wooden mast about 6 meters high from which a single antenna wire extended into the individual trucks. Three semi-undergro nd bunkers for vehicles w$re also observed in the installatio nd along the eastern side a flat bunker which was surrounded by a double arbed wire fence. This bunker was connected to the Token and radio trucks by lines. Six additional wire lines extended from the bunker into the quartering area of the airfield. These lines were suspended from wooden masts about 3 meters high with simple cross bars. Two more lines with porcelain insulators lead toward the Artillerie Kaserne. A total of 40 to 50 x 200-liter barrels were stored close to the earth bunker. The radar sets were not in operation on 8 March. However, on 24 January between 0930 and 1500, the Kniferest had continuously rotated making one rotation within about 6 seconds. About 6 soldiers moved between the radio trucks. An additional 15 soldiers wearing black-bordered blue epaulets marched from the quarters at the field toward the radar station.4 Gardelegen radar station. Between 12 and 17 March 1955, the radar station 25X1 on triangulation point 63.2 northeast of Gardelegen was occupied by 1 Token, 1 Kniferest and 2 Fishnets, the latter 30 to 40 meters apart. The Token-type set occasionally rotated during the morning and late afternoon. The previously reported wire lines leading from the installation toward Garddlegen and to triangulation point 47.7 west of the barracks installation at the field consisted of 4 white wires each. The overhead line extended south of #weitriangulation point 47.7 parallel to the highway leading toward Klosterheuendorf. The line wax underground under the railway underpass of the spur track leading to the barracks installation at the field. An air force officer with several NCOs who presumably belonged to the radar station were repeatedly observed in Gardelegen.5 6. Gotha radar station. On 5 December 1954, ^ Token-type set was north of the Flak Kaserne west of Gotha. A Kniferest-type set 1Obout 10 meters from the Token. Three radio trucks were parked in dug were protected by wooden roofs. Insulated cables of various dianii extended from the Token and radio trucks to two wooden masts where the cables were tied up in a bundle and lead on to the Flak Kaserne.6 7. Plauen radar station. On 3 April 1955, 1 Token and 1 Kniferest were still 25X1 observed in the radar station near the water tower west of Plauen. A second Kniferest-type set had repeatedly been set up and dismantled in the installation prior to 3 April. Two small barracks were still observed just next to the Token-type sets The soldiers who operated the installation were black-bordered blue epaulets and probably had their quarters in Kirchbaoh Kaserne since q"n going back Approved For Release 2008/10/28: CIA-RDP80-0081 OA007100480003-1 Approved For Release 2008/10/28: CIA-RDP80-0081 OA007100480003-1 SECRET 25X1 S-E-C R-E-T 1-8. Wittenberg radar station. On 15 April 1955, the Token-type set was still observed on Apollensberg west of Wittenberg,.It rotated slowly between 0900 and 1200. Each rotation lasted 30 seconds. A radio installation with a single mast 8 to 10 meters high and with an egg-shaped masthead was observed850 to 100 meters from the Token on the slope of Apollensberg. 9. Radar station on "Kleiner Entenfaengerberg" near Werder. On 19 January 1955, a radar set similar to a Token-type set, was still observed on "Kleiner Entenfaengerberg" about 2 km east of Werder/Havel, 1 km south of the Potsdam-Werder railroad line. Observations were made from a distance because the area around Entenfaengerberg was blocked and the set could not be seen through the thick tree-tops at the foot of the mountain. The radar set was apparently mounted on a fram tree-tops. The upper grid frame had a slanting position box underneath which rotated together with the upper fr was definitely observed. A second grid frame could not be'Tfftn ified. It was possibly hidden behind the tree-tops. It was observed that the9set only rotated in an anti-clockwise direction and in clear weather. 10. Demmin radar station. On 28 January and between 9 and,14 February 1955, a radar station with a dDumbo-type set surrounded by a barbed wire fence was observed at the eastern exit of Demmin south of the road to Jarmen, about 600 meters east of the cemetery. There were also 2 masts interconnected bat an antenna from which a lead-in extended to a radio truck barked next to the Dumbo. A total of 3 radio trucks were observed. Soldiers who were employed in the installation wore black-bordered blue epaulets' and were quartered in earth ~8nkers. The Dumbo occasionally rotate, aking 2 rotations in 1 minute. 11. Radar station near Neuhaus am Rennsteig. On 14 April 1955, a Soviet installation;; probably a radar station, was observed at the southwestern exit of Neuhaus am Rennsteig along the Steinheid-Neuhaus road. A 2.5- meter-high board fence surrounded an area of about 275 x 50 meters where a former villa and 2 ante systems, one about 10 meters high and the other about 15 meters high, ere located. The bases of the masts were sunk in angular irons about 15 m wide. The 10-meter antenna consisted of 3 double cross bars, each cross bar with 8 aluminum rods about 15 mm in diameter. The 15-meter antenna had 2 such cross bars. Tvuo Soviets with crimson epaulets and without weapons were seen in Neuhaus. One officer wearing red-bordered yellow epaulets with red longitudinal stripes and 2 stars side-by-side left the villa. about 60 Soviets with crimson epaulets were quartered in the installation in addition to some Soviet families who were billeted in the former villa. Three trucks allegedly belonged to the radar station. A similar radar station was alleudly located on Arnsgereuther Hill between Neuhaus and Probstzella. 12. Air warning station near Rudolstadt. After 15 January 1955, a superstructure 4 to 5 meters high was erected on the platform of the so-called Luisenturm on Hummelsberg, about 10 km north of Rudolstadt between the Kleiner amd Grosser Kochberg. Work was terminated by late February. The superstructure including the roof was built in the form of a half-timbered frame with the spaces being filled with glass, thus providing a panoramic sight. On 25 February, some rods, probably rod antennas, were seen fitted to the 25X1 25X1 Approved For Release 2008/10/28: CIA-RDP80-0081 OA007100480003-1 Approved For Release 2008/10/28: CIA-RDP80-0081 OA007100480003-1 ill 2 VP men armed with rifles were observed at the foot of superstructure. During the first phase of construction work, two Soviet officers had allegedly been seen on the tower. On 19 January, truck d presumably 5 female VP personnel on top of the tower. s wef seen. Recently, no Soviets have been observed at ion. 13. Stahnsdorf radio installation. On 28 March 1955, a radio installation of 4 masts arranged in a square was observed about 200 meters south of Ludendorff Kaserne in Stahnsdorf. The masts were about 6 meters high, braced in 2 places about 8 meters apart. In the middle of the installation a four-cornered wooden hut about 3 meters high was seen. A similar radio installation was located about 30 meters north of the first installation. Between the two installations was a guard tower about 5 meters high which was permanently occupied by a sentry. .On 12 April, the southern installation except for the wooden hut was dismantled and a similar 4-mast station was established about 80 meters south of the hut. A van-like truck was observed between the masts. No cable lines were seen at this installation. The northern radio installation was still unchanged. A third 4-mast radio installation with a wooden hut was seen about 250 meters north of Siegfeld Kaserne on 12 April. No soldiers o4ehicles were seen, but a sentry was posted there. Besides these installations, many antennas or lines of unidentified installations were seen in the area of Siegfeld Kaserne and Ludendorff Kaserne. 14. Radio installation at Fuerstenwalde airfield. On 22 March 1955, a new radio installation was observed on the former Fuerstenwalde airfield. The following installations were arranged from east to west; two twin-mast installations about 50 meters apart; about 100 meters farther west and unidentified set; and about 50 meters west of the latter occupied by 5 Soviet officers, had been seen coming direction of Rudolstadt and moving toward Luisenturm. A barracks constructed next to the tower. he individual installations. About 60 men received instruction radio installations. The individual two-mast installations consisted twin-mast installation. A radio truck with a rod-antenna was parked of 2 wooden masts about 12 meters high, about 25 meters apart from th north to south, and interconnected with a line. The unidentified installation 1 mast about 8 meters high braced at one point. nna which had the cross shape of the Kniferest was esh wire netting. The entire superstructure seemed to have the shape of a box. About 101~rucks and 10 tl 15 radio trucks were parked in front of the eastern hangar. 15. Radio installation at Johannisthal airfield. After 15 March 1955, two 4-mast radio installations were observed at Johannisthal airfield. One installation was located in the middle of the field and the other at the western edge of the former landing field. Soviet officers and soldiers were repeatedly seen moving between th75former installation and the depot of the former Organization Todt. 16. Radar set at Schoenwalde airfield. On 7 December 1954, the following sets were located on the drill grounds of Schoentalde airfield: 1 RUS II on a propped-tulp trailer 1 generator on blocks, slightly dug in and surrounded by planks 1 radio truck with 2 vertical rods about 1 meter long on the roof.

On 25 January 1955, no special activity was observed in the radar station: Six soldiers were seen near the group of motor vehicles and 4 soldiers near the Kniferest-type set. 4. Perleberg radar station. On 8 March 1955, the following radar sets were observed in the installation: 1 Token 1 Knifereat 1 Fishnet 4 radio trucks. Three of the 4 radio trucks had a wooden mast about 6 meters high from which a.single antenna wire extended into the individual tracks. Three semi-underground bwikers for vehicles were also observed in the installation, and along the eastern side a flatrbunker which was surrounded by a double barbed wire fence. This bunker was connected to the Token and radio trucks by lines. Six additional wire lines extended from the bunker into the quartering area of the airfield. These lines were suspended from wooden seats about 3 Deters high with simple cross bars. Two more lines with porcelain insulators lead toward the Artillerie Eaaerns. A total of 40 to 50 x 200-liter barrels were stored close to the earth bunker. The radar sets were not in operation on 8 March. However, on 24 January between 0930 and 1500, the Kniferest had continuously rotated making one rotation within about 6 seconds. About 6 soldiers moved between the radio trucks. An additional 15 soldiers wearing blank-bordered blue epaulets marched from the quarters at the field toward the radar station.4 5. Gard. leap r et Migg. Between 12 and 17 Marsh 19559 the radar station 25X1 on triangulation point 3.2 northeast of Oarielegen was occupied by 1 Token, 1 Kniferest and 2 Fishnets, the latter 30 to 40 meters apart. The Token-type set occasionally rotated during the morning and late afternoon. The previously reported wire lines leading from the installation toward Gardalegen and to triangulation point 47.7 west of the barracks installation at the field consisted of 4 white wires each. The overhead line extended south of triangulation point 47.7 parallel to the highway leading toward Kloeterneuendorf. The line was underground under the railway underpass of the spur track leading to the barracks installation at the field. An air force officer with several 11116COs who presumably belonged to the radar station were repeatedly observed in Gardelegen. 6. Gotha radar station. On 5 December 1954, a Token-type set was observed north of the Flak Kaserne west of Gotha. A Kniferest-type set was plaoed about 10 meters from the Token. Three radio trucks were parked in dog-onto which were protected by wooden roofs. Insulated cables of various diameters extended from the Token and radio trucks to two wooden masts whets the cables were tied up in a bundle and lead on to the Flak Kaserns. 7 Plr_uen radar static: On 3 April 1955, 1 Token and 1 8niferest were still 25X1 observed in the radar station near the water tower west of Plauen. A second Kniferest-type set had repeatedly been set up and dismantled in the installation prior to 3 April. Two small barracks were still observed just next to the Token-type set.

A radio installation with a single mast 8 to 10. meters high and with an egg-shaped masthead was observed850 to 100 meters from the Token on the slope of Apollensberg. 9. ?far eta on_onn"glain*r_ En_tenfae gerbepy near We er. On 19 January 1955, a radar not similar to a Token-type set, yeas still observed on "Kleiner Entenfaengerberg" about 2 km cast of (erder/Havel, 1 km south of the Potsdam-Warder railroad line. Observations were made from a distance because the area around :!;ntenfaengerberg was blocked and the set could not be seen through the thick tree-tops at the foot of the mountain. The radar set was apparently mounted on a frame in line with the tree-tops. The upper grid frete had a slanting position and a resta le-shaped box underneath which rotated together with the upper frame, This movement was definitely observed. A second grid frame could not be identified. It was possibly hidden behind the tree-tops. It was observe& that the9set only rotated in an anti-clockwise direction and in clear weather. 10. Domain radar station. On 28 January and between 9 and 14 February 1955, a radar station with a Dumbo-type set'surrounded by a barbed wire fence was observed at the eastern exit of Dammin south of the road to Jarwen, about 600 meters east of the cemetery. There were also 2 masts interconnected by an antenna from which a lead-in extended to a radio tr?nk -narked next to the Dumbo. A total of 3 radio trues were cbserved. Soldiers who were employed in the installation wore b ac -bordered blue epaulets and were quartered in earth Vunkers. The Dumbo oacasiona~ly rotated making 2 rotations in 1. minute. i1 Radar station near Neuhans_am Rennateig. On. 14 April 1955, a Soviet installation, probably a rada:: station., was observed at the southwestern exit of Neuhaus am Rennsteig along the Steinn.id-Neuhaus road. A 2.5- meter-high board fence surrounded an area of about 275 x 50 meters where a former villa and 2 ,antenna systoms, one about 10 meters high and the other about 15 meters high, were located. The bases of the masts were sunk in angular irons about 15 cm wide. The 10?-meter antenna consisted of 3 double cross bars, each cross bar with 8 aluminum rods about 15 an in diameter. The 15-meter antenna had 2 such cross bars. Tara soviets with crimson epaulets and without weapons weira seen in Neunaua. One officer wearing red-bordered yellow epaulets with red longitudinal stripes and 2 stars side-by-side left the villa uartered in the installation in addition to some Soviet families who q were billeted in the former villa. Three trucks allegedly belonged to the radar station. A similar radar station was a11e Idly located on Arnagereuther Hill between Neuhaus and Probstsella. 12. Air warning station near Rudolatadt. After 15 January 1955, a superstructure 4 to 5 meters high was erectad on the platform of the so-called Luisentura on 8ummelsberg, about 10 km north of Rudolstadt between the Kleiner amd G.roaeer Kochberg. Work was terminated by late February. The superstructure including the roof was built in the form of a half-timbered frame with the spaces being filled with glass, thus providing a panoramic sight. On 25 February, some rods, probably rod antennas, ware seen fitted to the 25X1 25X1 Approved For Release 2008/10/28: CIA-RDP80-0081 OA007100480003-1 Approved For Release 2008/10/28: CIA-RDP80-00810A007100480003-1 The two rods were about 3.5 meters apart and interconne,3ted by a horizontal rod from which 4 '.look-like bars branched off. A sk:stch was made of this set. 1 similar set located at some distance and arrsngod in such a way that the hook-like devices pointed to each other,. 25X1 Cable connections laid on the gronnnd and crossing the spur track on poles were seen on all sees. Several-soldiers moved between the aet3. These sets were no longer observed at a::out 1000 on 5 February 1955. On the roof of a building was a SCR-534 radar set which slowly rotat-ad to and fro. A Pegmatit radar set which did not rotate was mounted on the same building. Soldiers wore seen c.rill'.ng with 8 x,25-mm AA guns, including some in emplacements, on the I:rain!ng grounds 17. Radar set near Sehoenval lde -ijfield. On 8 .January 1955, a model AA 4 IBC 3 radar set, counted on a she: about 6 meters long, 4 meters wide and 4?5 meters high, was observed south of-Schoenualde airfield about 200 meterp east of the Boetsow-Sohoenwal.e road. * could not be determined whether a radio ,~ruok was parked in ':.iia shed., 18. Radio installation north of Feissen. O 12 Marsh 1955, a ?our-mast radio i.nstallat son was locatf%.. abcnt 500 meters went of the Yeissen-ORcrilla road in line with the Bohni';cscb :arraeks inat~.llation? The masts were about 6 meters high and arran*.e!d in a square each side about 10 w4ters long. A wuoaen hut was located in the middle of the square. Onl,4 Me Soviet sentry was observed in the ?,nstalLation. Another similar inetall:.tion which had been observed be txeen the former installation and ;!:e 2 eissen-Okril.la :,-Lad in late Februar was ac longer seen on 12 blarch.,i7 19.. Air warninrr comuanv, Q KTP di aionin Zgea ,;:Karpin area, During March 1955" an air warning oom:^.xny of about 80 men vLs activated from volunteers of units of the KVP divisio?.in the E gesin-Parpin area. Training was done in the quartering sectior A in Parkin. Then the unit was transferred to Gumnits. Four soldiers of his air warning company were always posted on an old tower of reinforc.,d concrete about 25 meters high and located. about 100 meters east of tl?a Torgelow-Eggesin railroad '.ins about 500 meters south of Gumnitz. The lower had a direct telephone connection to the division headquarters in 'ggeein where all aircraft crossing this area were reported. The u;?er section of the tower housed a day room for the sentries. Special sets to-, detecting flying aircraft were not yet available. 1. omment, The Flak Kaserne in Wismar is occupied by 1 motorized rifle regiment and I heavy gun battalion that are definitely not connected with the mentions radio and radar installation which are presumably used for air traffic ontrol and air warning service. 4', Commer T e ,mat is -type set was established in the Hagenow installation 25X1 in August 1t4 when the Token-type set was dismantled for a few days. T. Taken was p:tbably plated on an earth wall because of the low position of the lower reflector which would be hampered in its action by low obstacles,, :toms .s. During September 1954, a Fishnet was observed next to the Kni erest iL the radar station at Ludwigslust--'rrhentin airfield. Comore:'.,,. A second Fishnet was observed in the Perleberg mddar station in tower 1954 The flat earth bunker possi",ply housed a computing station:: S-K-C-R-E-T Approved For Release 2008/10/28: CIA-RDP80-00810A007100480003-1 Approved For Release 2008/10/28: CIA-RDP80-00810A007100480003-1 5. Comment. No changes occurred in`tl - W Gardelegen radar station wher compared with observations made in October 1954. 6. Comment. The Flak Kaserne in Gotha is occupied by elements of the 57th Gds Not Rifle Div which is ::got connected with the radar station. According to previous reports, Only 1 Token was seen in the installation. 7, 9. Comment. According to previous observation8, 1 Fishnet belonged to Plauen radar station. This set was apparently not seen on the day of observation. Count. The Token on Apolleneberg near Wittenberg probably belongs to the headquarters of the Southern Ftr Corps which is stationed in Kittenbera. LComment, Another radar station with 1 Token, 1 Kniferest and 1 Dumbo was observed on triangulation point 62 about 1.35 km south-southeast of Glindow in November 1954. The two radar stations probably belong to the headquarters of the Twenty-Fourty Air Army in Warder. ~Comnent. The radar station near Demmin is reported for the first time. It closes the gap between Puetnitz and Rechlin-Lears, ommQnt. During June 1954, 1 Kniferest, 1 Fishnet ani presumably 1 n o were observed in Neuhaus am Rennsteig.. It cannot be determined if tweae sets are identical with the sets mentioned in the present report. For sketch of seta, possibly of type Kniferest, seen on 14 April 1955, see Skertah 1. 12. I Comment. The air warning station near Rudolstadt is reported for the first time. This indicates that an air warning organization is to be established in the GDR. 13. 14. gomment. The Schlieffen Kaserne in Stehnsdorf is occupied by the 66th 25X1 Sig Regt of the OSYG. The radio installations observed are possibly used for the training of signal personnel, Comment. The quarterin g buildings of the former Puerstenwalde airfield 25X1 are occupied by elements of the 63rd IA Div. The installations observed are probably used by AA personnel for training purposes. Comment. The radio installations on .Johannisthal airfield are reported or the first time. Comonent. Elements of the 31st AAA Div arc quarteredjn Schoenwalde airfield., The s4ta observed are fairly definitely used by these units for training purposes. For sketch of new set, see Sleatoh 2, Comment. The barracks installation in tteissen-Bohnitssoh is occupied by tank and AA units of the Soviet Arsy. It is unknown whether the reported radio installations belong to these units or if they operate as DP Installations within the framework of the air traffic control system. Comment. These are indications of the activation of air observation units within the VP.
