Yak-25M, yak-25MG, by A.S.Yakovlev ('Flashlight-A')

30k Yak-25M drawing from Yak-25 at the Russian Power

In November 1953 the 'Sokol' radar station was finally ready for service. It had substantial advantages compared to RP-1 aiming radar used on early production Yak-25. Among other advantages, 'Sokol' was capable to track low-flying targets (300m above the ground). In April 1954 station was tried on Yak-120 interceptor and put into production under RP-6 designation.

Governmental order N°899-385 was issued on May 13 demanding to start production of 'Sokol'-equipped Yak-25 immediately, but in fact it started only in January 1955. Aircraft was designated Yak-25M. It had improved RD-5A (AM-5A 2nd Series) engine. Guns were equipped with muzzle recoil absorbers, fuel capacity was increased.

Some Yak-25M were equipped with 'Gorizont-1' (Horizon-1) system, allowing 'blind' aircraft aiming by ground based radar(s). Those interceptors were designated Yak-25MG.
