The ABR8-220 is an air-to-air powder rocket missile. The design of the.ABRS-220 is a modification to the RB-100-S rocket missile 'develOpid in Germany during World War II.

Power Plant. The fuel consists of sticks of compressed Diglycol powder,weighing 24 kilograms. The total impulse produced was 7,400 kg./sec., and the thrust was found to be 190-195 kilograms. Terminal speed was 440 meters/sec. plus the speed of the aircraft. (3. Accuracy. The ABRS-220 is a spin-stabilized, uncontrolled air-to-air missile. The design requirement put to our group was one out of two hits on bomber targets. A considerable portion of the time spent by the group on this project was in carrying out calculations of disper- sion. Three different methods of obtaining a rotary motion were considered as follows: (1) Canted )ocket thrust (2)Assymetric spoilers on the fin stabilizer (3) Canted cruciform fin stabilizer. I rejected the third method, because the Soviets would not have been able to manufacture the parts with the required accuracy. d. Tests. Models of the A3RS-220 were ,tested on the ground firing range at Krasnoarmeyskiy. Not enough tests were Conducted to determine the accuracy of the missile., / did not witness any .ait..firinglosts. 10. After-aompletion of the German activity on ABRS-220, it was discovered that the Soviets were engaged in theoretical and practical aspects of a similar project. The results of the Soviet tests made in competi- tion with the German built model's were not made known to me. The Soviets evidently placed a high priority on this project as .evidenced from, the following. At the end of the work on.this project,I was asked to give a lecture on the ABRS-220 design. The lecture took place at the Soviet institute near the Yaroslavskiy railroad station and was attended by a great number of guests including high ranking officers and civilian specialists. This project was terminated by turning over to the Soviets complete plans, descriptive literature, and technical instructions. The Sokol Missile 11. In the spring of 1947 my group was pressed to take up work on a controlled air-to-air missile based on the "Falke" development. In Berlin, where a certain amount of preliminary work had taken place, the term "Super-Moeve" was applied to a supersonic version of "Falke." 'In the USSR this project was dubbed "Sokol." . 12. I successfully put off working on "Sokol" at this time by pleading inadequacy of personnel and facilities to carry out a controlled ? missile development. The Soviets accepted my reasoning that "Sokol" was not feasible as long as they did not have wind tunnel results and a control mechanisms laboratory. I was told that.' would receive the wind tunnel data in due time and in the interim was assigned another project, the ABRS-240 See paras. 16 -19 belog. 13. However, a considerable amount of pressure was put on my group to continue our work on the "Sokol" design. In spite of the handioaps, I was forced to accede to the Soviet desires and started to work on. it on or about 1 January 1948, without benefit of an appropriate CONFIDENTIAL Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 50X1 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 CONFIDENTIAL - 6 - laboratory, adequate. personnel, and wind tunnel faoiliiiiiTtFhie project represents the only missile worked on in the USSR, which.

After a meeting at the Secret Section of the, Ministry of Agricultural Machine Building, it which the casief.engineer of the Ministry was present, it Was decided to have out group prosecute the "Sokol" design intensively. In the place of experimental wind-tunnel data, I was told to use my mathematiaieni for verification of the design.

CONFIDENTIAL - 7 - that wind tunnel tests would only lead to minor modi . The lack of verification did not appear to disturb the Soviets. Their interest seemed to lie in the system design. As a part of "Sokol", a new servo control system was designed. It was to be driven by a propeller-driven generator. Where our group was incapable of carrying out detail design, approximate dimensions and weight were given to the Soviets, along with broad functional characteristics. The design was completed about August 1948 and turned over to the Soviets along with the supporting theoretical caloulations, ballistic and hit probability calculations. This included a study of the effect of human error in the control system. The data was tuned over and discussed at a technical meeting at KB No,), ant the project was dropped abruptly by our group. All the data and documents were sealed and sent by courier to another location. No Permeate ever .came to our group on "Sokol" after this meeting. The ABRS-240, "Molnya" 50X1-HUM As a substitute to the "Sokol" project, the Soviets asked us whether we could build an air-to-ground rocket with the following characteristics; ? a. 1000 - 1200 meters range b. 50 per cent of missiles in a target area one meter square. I complained that this accuracy was impossible with an uncontrolled rocket, but our reply to the fulfilling of these requirements was the A3RS-240 "Molnya." 17. In April 1947, our group began the design of ABKS-240. The design itself was based in part on certain intuitive assumptions by me and the group, i.e., optimum power for the missile, size-of stabilizer, rpm of main missile, etc. As the detailed design progressed and calculations were made, the rough design proved to be optimal in all phases. The Soviets were skeptical about the reliability of expelling the projectiles without detonating them, the stability of the projectiles, and the type of explosive pattern that would be formed; as a result, permission was given to make :three test Missiles. These were assembled from parts made in the Soviet experimental workshops at Krasnoarmeyskiy. ao 'Design Characteristics. ? .The ABRS-240 is an air-to-ground anti-tank missile containing ? seven projectiles in the warhead. This missile was to be fired from relatively slow aircraft (420 km./hour). The ? terminal speed of the missile was designed to be 114 meters/ sec. plus the aircraft speed. The warhead contained a cluster of seven powerless projectiles which were ejected a few hundred meters in front of the target by explosive charge detonated by the change in pressure in the rocket motor after burning out. Upon expulsion from the body of the missile, the projectiles were accelerated tangentially because of the rotation of the .main missile. The center projectile remained on the same course as the main missile. The result was that the projectiles caused a ring-like pattern in the vicinity of the target. The projectiles CONFIDENTIAL Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 50X1 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 ? ?

After several hundred yards of flight, the ejection of the projectile took place and then separated from the missile. airframe. The folding fins opened and the projectiles stayed on course., Even the empty airframe, without ?give, stayed on coUree. After the tests, the project was assigned a high priority and efforts were concentrated on complet- ing it in the shortest possible time. 18. After the tests, our group received official requirements for an improved ABRS-240 to decrease the caliber, decrease the size and warhead of the projectiles, and increase the penetration capacity of the projectiles.- These requirements were as follows: Total. Weight " Caliber of missile , Caliber of projedtiles Penetration power Firing ?

After the test firing of the ABRS-240, a Soviet design group in KB No.5 was given the new requirements and began work on the design of an improved ABRS-240. I saw, during visits to the experimental workshops, parts being manufactured that could be definitely identified with ABRS-240. I noted that several changes had been made by the Soviets in the manufacture of the missiles. For example, a leather gasket was changed to cardboard allowing some of the combustion gases to escape. In order to prevent any further knowledge of this activity, an order was issued in the:winter of 1948-1949 placing the workshop off limits to German personnel. The Zenith Missile 20. The Zenith design resulted from the Soviet requirement for a cheap, uncontrolled mass antiaircraft weapon. The following detailed requirements were given to our group in the fall of 1948, after the "Sokol" project was terminated: CONFIDENTIAL Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 CONFIDENTIAL - 9 ?

We developed a design of a two-stage, ground-to-air solid propellant rocket to meet .the above requirements. The design included all the important details. However, the theoretical ballistics carried. out in support of this design were rather sketchy. The design, once it was decided to use a two-stage missile, was based on old . ? values wii.remembered were used during wartime at Rheinmetall-Borsig. ?This design, with supporting literature, was turned over to the Soviets at KB No.3. Lit is interesting to note that the data on the Zenith was not translated until nine months later, and at that time, sent to the Agricultural Ministry. At this time, several questions were asked abolt the Zenith, on length of time for development, 'and, several minor items. The total spent on this project was three monthsA7 22.

It was believed that a quick release catch mechanism would allow the second stage to be fired alone against low flying targets. Inside of the peg was a delay powder composition which was coupled with the pressure-igniter. This pressure- igniter was activated by the propellant gases of the first stage. Inside is a cylindrical drill-hole in which a copper- ? sealed piston is located. The piston is thrown forward by the gases of the first stage. In its forward position the piston-hits the firing pin which ignites s percussion cap. This results in the combustion of the delay powder composition. The Forward Sealing Panel of the Firstfitage A Clamped steel part which had a threaded connection on the frontal interface as will as in the curved position. This curvature permitted an additional centering of the casing of the second stage. The sealing panel had an outside thread which was screwed on to a steel ring. .The steel ring in turn was connected with the 2.7 mm. pipe by means of a welded /Sam. The caliber of the steel pipe was approximately 120 atm. On two diametrically opposed places on the forward sealing panel, pigs protruded in which the guide pin was screwed. .Through this guide pin, the igniting voltage was to be fed ' to the missile igniter. For this purpose an electrical percussion cap was placed in the shaft of the guide peg. The explosion of charge ignited the centrally located powder charge. Point 16 Black Powder Charge ?. The blaok powder charge was contained in a thick-walled . celluloid capsule which had weak points around its cir- cumference. These permitted the penetration of the igniting explosion. The celluloid capsule was centered ' by means of a centering ring. Point it Centering Ring This-Wat'pressed of deep drawn steel.

It consisted of a Stall ring approximately 3 mm. thick which was provided around its circumference with three flat iron strips to cater the missile's combustion chamber. Point 22 Sealing Panel this panel, was also joined to the nozzle. It was a preesed part constructed .from a thick-walled pipe. The ..thick-walled pipe was turned out in the direction of the gas jet in order to obtain an enlargement of the cross- section'. The necessary enlargement for the missile's Combustion chamber was to be achieved by a high-temperature process. The connection between the panel and the pipe was to be effected by means of a circular welded seam.' Point 23 Conical Steel Casimir This was designed as a fairing to enclose the nozzle. The fairing also served as a means for attaching the four 'control 'surfaces. joint 24 Control Surfaces 'The Ring Magazine Missile 23. During World War II, the Germans had planned to improve the RB-100-S air-to-air missile by using small ballistic explosive projectiles in the warhead instead of the incendiary cylinders. This improvement was called "Miki." After the "Zenith" project, the Soviets wanted our group to continue along these lines. ,The Soviets did not approve of the cluster warhead, nor of the 4ength-.of,the missiles designed. They consequently gave new requirements, in general to shorten the over-all length, and utilize a. ring magazine construction; these requirements were as follows: Range Speed differential Warhead Projectile Fuses Main Fuse In'a short time, many diffe the representative ones are 800-1000 meters 350 meters/sec.

The Ring Magazine missile follows generally the design of the RB-100-S. Ten different designs were carried out over a period ? of two months. They differed from the basic design in methods of expelling the projectiles and numbers of projectiles. The airframe of this missile was approximately 1.5 m. long and Approximately 300 mm. in diameter. The propellant, like all the ? designs carried out at Krasnoarmeyskiy, was solid powder sticks. Stabilization was to be maintained by a cruciform tail. The -Projectiles were to be ejected after a time delay and form a cone 9 O'NFIDENTIAL Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 50X1 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 25. 26.

In the final reports on these designs, drawings were included which did not show all the design details. Kowever,-the -propulsion unit itself was - fairly complete in order that fabrication could be started immediately by the Soviets. The hiallistic Calculations were carried out only far the critical values and not in as great detail as on the earlier projects. The work was principally engineering design, and only, 30 per oent of the group's time was spent on ballistic calculations. Nothing further was said to us after oup reports were made on this missile. During the winter. of 1951-1952, I accidentally observed test firings of., missile which was undoubtedly built along the lines of the "Ring Magazine" missile. Since the altitude of the aircraft was approximately 10,000 ft., I could only count the burets and determined row this that several of the variations in the de040,1 were built. Some showed 24 bursts; others, 50 bursts; and ori9X1 -HUM, as many as 70-80 bursts. see page 11 of Report We were clirected to design a launching device to be housed in an aircraft of-unspecified dimensions and configuration. This device was to launch 48 air-to-air missiles in succession. Dur- ing this time, there was a closer working arrangement between the Soviet military and the German group. A colonel (Air Force) came often for briefings and occasionally offered suggestions as the design progressed, but I do not remember his name. Be was a permanent representative of the Soviet Air Force at Kras- noarmeyskiy. The Automatic Rocket 27. The Automatic Rocket, is a weapon similar to the "Mighty Mouse" air-to-air missile. An automatic launching device fires 48 air-to-air missiles from the mother aircraft. The missiles of this weapon are not controlled. The design of the Automatic Rocket comprised two pods which carried 24 missiles each. The missiles were mounted on an endless belt which was rotated by motor. As each missile reached the lowest point in its travel, it was automatically released by an electrical contact made at that point. Every other missile was set back a few inches, to prevent malfunction from contact between adjacent missiles. The order of firing was such that the front row was fired first, and then the second. The endless belt thus made two full CONFIDENTIAL 50X1 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 50X1 50X1 Declassified in Part - Sanitized Copy Approved for Release 2013/08/09: CIA-RDP81-01030R000100360005-6 CONFIDENT IAL - 14 - 50X1 . m ravitlutinnn Aron nagn.35 for drawing of the Automatic Rocket. ? ? 50X1-HUM 28. .Thia.projeet irse initiated in May 1949 and was completed in Auguit 1949.

In the last few weeks of 1949, our group was directed to oirry out penetration tests of 13115-240 projectiles. I cannot give much information on this subject, in view of its short period of duration and my lack of direot contact with it. I do knew, however, that the warheids involved showed i penetration of 800-800. millimeters.
