USATC, Series 200, Sheet 0167-5, scale 1:200,000 1. A small, probably incomplete, airframe was observed undergoing structural testing at Moskva Aircraft Experimental Plant 51 (Figures 1 and 2). The size and configuration of the airframe suggest that the design bureau headed by P. O. Sukhoy may have developed a new small fighter. 2. The new airframe (Object Target Number Figure 3) was rig in the west plant area. Components which were discernible included the wing and probably a partial fuselage. The wing was delta in planform and appeared to have a compound sweep on the leading edge. Because no cockpit or tail surfaces were observed, it is possible that the airframe was mounted in an inverted position within the test rig. A review of photography revealed that the airframe was in the test rig 3. The structural test rig, just north of a probable airframe inlet and engine test facility, was completed as early as March 1972. It consists of a metal framework constructed on a concrete pad. A probable hydraulics fluid storage tank is nearby on the west side. Structural test rigs of this type are used for airframe fatigue testing. During fatigue testing, the entire airframe or portions of the test aircraft are subjected to dynamic loading to simulate actual flight conditions. These loads are applied through hydraulic jacks and other specialized equipment. The test data is recorded and analyzed to ascertain possible deficiencies in the design of the aircraft. It is possible that the airframe at Plant 51 has been mounted within the rig in an inverted position to acquire negative load data. 4. Plant 51 houses the Sukhoy Design Bureau (OKB) and functions as a prototype production plant.' Located on the southern side of Moscow Central Airfield and bordering the western edge of Moscow Airframe Plant 30 , the plant contains approximately 800,000 square feet of floorspace. Sukhoy's OKB has been responsible for the design and development of some of the principal fighter aircraft in the Soviet Union. These include the FITTER series, FISHPOT, FLAGON, and FENCER A. 5. There has been some activity which may be related to the development of a new aircraft at the Sukhoy flight test support facility (Figure 4), at the Ramenskoye Flight Test Center (BE In July 1974, footings for a new unidentified building were observed. When completed, the new building will be In September 1974, a new large parking apron was seen under construction. A large area had been graded and the laying of concrete segments was in progress. 25X1 25X1 25X1 25X1 25X1 25X1 25X1 25X1 -1- Top Secret PIR-009/75 Sanitized Copy Approved for Release 2011/07/14: CIA-RDP78TO5162A000400010075-5 Sanitized Copy Approved for Release 2011/07/14: CIA-RDP78TO5162A000400010075-5 Top Secret RUFF r8?\ MOSCOW/SHEREMETYEVO AIRFIELD MOSCOW/KHIMKI AIRFIELD Kra$nogorsk Railroad, double track Railroad, single track MOSCOW/BYKOVO Byko vo\- AIRFIELD MOSCOW/RAMENSK MOSCOW/MYACHKOVD AIRFIELD "MENSKOV FLIGHT TEST CENTE J _\ FIGURE 1.
