evelopment of high altitude target drones based on Yak-25RV started in 1958, even prior trials of the experimental reconnaissater. Yak-25RV-I was intended as manned target for fighter-interceptors, practicing unarmed interception of high altitude targets. Difference from series Yak-25RV by deleted photoequipment. There were no surprises during trials (finished in 1961), and limited series production started in Ulan-Ude.
Minor improvements, introduced during production, resulted in 240kg weight savings, what was quite substantial for high altitude performance (August 1962).
If necessary, Yak-25RV-I could be re-equipped for unmanned operation. Standard unmanned version was designated Yak-25RV-II and was used by high altitude interceptor regiments for life firing practice. Yak-25RV-II was equipped with P-28 autopilot and remote control set. It was guided by specially modified Yak-30 trainer.
Retired reconnaissaters Yak-25RV were also converted into target drones.
