The first prototype, called "23-01" but also known as the MiG-23PD, was a tailed delta similar to the MiG-21 but with two lift jets in the fuselage. However, it became apparent very early that this configuration was unsatisfactory, as the lift jets became useless dead weight once airborne. The second prototype, known as "23-11", featured variable-geometry wings which could be set to angles of 16, 45 and 72 degrees, and it was clearly more promising. The maiden flight of 23–11 took place on 10 June 1967, and three more prototypes were prepared for further flight and system testing. All featured the Tumansky R-27-300 turbojet engine with a thrust of 7850 kp. The order to start series production of the MiG-23 was given in December 1967.
