La 17R device is an improvement over the target La-17, which has a qualitatively better performance and technical indicators. The new machine must perform more qualitative intelligence work. To this end, it was equipped with a powerful type of aerial cameras AFA-BFA-2K. It started developing in 1957 year, with the powerplant used RD-900. When construction abandoned corner reflectors, and the fuselage and wingtips fabricated from metal.
Design calculations showed that the device will be able to conduct high-quality flight at an altitude of 7 kilometers flight range in 170 km. In clear weather, this machine could carry out an excellent shooting position of the enemy. When the bend radius achieved its target of 5,4-8,5 kilometers. It should be noted that when planning a height 7 kilometers unmanned La 17R could fly even 56 kilometers.
In 1959 the Council of Ministers put forward their demands to the new car, which is within the range of not less than 100 kilometers and speed in 900 km / h. Suffice severe requirements demanded further improvements, after which La 17R not run with the Tu-4, but directly to the ground installation. This requirement was not the end, because it was necessary to create an unmanned reusable and thrust 1900 kgs. Furthermore, the flight depth was increased to 250 kilometers.
State testing devices La 17R were completed in the summer 1963 years. Following the results of the tests were obtained such performance characteristics:
Flight altitude 7 kilometers.
The flight speed of up to 885 km / h.
You can use the photo-reconnaissance of the objects that were deleted on 50 kilometers from the starting position, and at the height of 7 kilometers for objects on remote 200 kilometers.
Serial production unit La 17R began with 1963, the plant № 475, 20 here was made of such machines. On arms of a target used to 70-ies. Information about the combat application no. It should be noted that the apparatus model La-17 were the last aircraft devices, which bore the name of the great designer SA Lavochkin.
