In accordance with the USSR Council of Ministers Resolution of 1958 g. in OKB PO. Dry started developing an interception T 3-8M aerial targets with missiles K-8M. In OKB aircraft received the designation T-47. For writing at the request of the military "Diamond" radar and optical sight ASP-5H had to finalize the nasal part of the fuselage. To provide the required antenna patterns interceptor on the sides of the forward fuselage made cutouts, Closes the radio-transparent panels.
In January 1958 g. Test Pilot EK. Kukushev first raised T-47 in air. After 15 flying machine put on the joke, removing the pre-motor (He demanded for the fourth batch of PT-8-4, equipped as a cannon, and missile weapons). Converted PT-8-4 was different from other mass-produced cars engine AL-7F with the compressor blades, set at an angle of 9 °, and equipment for the oxygen run. several dozen different flight pilots were carried out on this machine. At the end of summer 1958 g. PT-8-4 airplane, piloted by test pilot E.V. Yelyan, After landing at high speed he skidded off the runway and was damaged.
AT 1957 g. factory number 153 should release 50 interceptor T-47. In total, the plant has built ten T-47 radar with "Diamond" and guns. The first production aircraft equipped with engine AL-7F and after the establishment of a resource were to be replaced with the AL-7F-1.
The first plane of the complex T-3-8M, not yet fully stocked equipment and armament, altered from batch PT-8 at the pilot plant DB-51. At the end 1958 g. began flight testing a prototype of the future head of the Su-11 under the designation T-47-3. Unlike machines with radar "Diamond" with the Su-11 prototype disappeared nasal radio-panel wing and "tooth". On both sides of the fuselage fairings electric cables stretched. The structure of the onboard T 3-8M interception complex equipment includes automatic control system interception "Air 1" with radio command line "azure" automatic data transmission and radar "Eagle". The airborne interception purposes provided in the rear hemisphere, flying at a speed of up to 1800 kmh.
At the end 1959 g. began joint state tests of the complex T-3-8M SD-K-8M. Act of the State Commission on the completion of the test was approved 8 June 1961 city, and a month later the plane T-47-8, piloted by test pilot EH. Solovyov, He took part in the parade Tushino. Aircraft missile system to intercept under the designation Su-11-8M was adopted in February 1962 g. The complex provides the interception purposes, flying at a speed of up to 1600 km / h at altitudes of up to 23 000 m. Range radar detection purposes was 25-26 km, and defeat the purpose of the launch of two missiles ensured with a probability of 0.8-0.9. In one of the test flights (pilot ispygatel B.C. Ilyushin) at about 20 km in the Su-11 engine refused. The pilot tried several times to start it, but to no avail. Ilyushin has managed to put the car without the engine for the first time in our country.
Compared with the Su-9 aircraft, The Su-11 was released a few (about 100), Yes, and they have served long. Operation Su-11 often accompanies high accident rate, often associated with the engine failure. The reason for this, According to the developers, It was discrepancy flow characteristics of the air intake and TRD. Su-9 and Su-11 were the most high-speed and high-altitude air defense aircraft to the country 1969 city, when they were replaced by MiG-25 fighter jets began to arrive. The last fighters of this type were withdrawn from service in 1980 city, ie. served to adopt a more 20 years.
