Oblik-Dummy was Zenit-8 (Oblik) spy sat, which has been in storage long beyond its service live and was converted to an instrumented dummy payload for the maiden launch of the new Soyuz-2-1a launch vehicle. The photographic equipment was removed and the vehicle was fitted with vibration and thermal sensors designed to measure the launch environment of the new launch vehicle.
The Soyuz 2.1A converted the flight control system from analog to digital, which allowed launch from fixed platforms. It also allowed big fairings and payloads.
