My dears Famvburg and Maveric,


as you know the work on Su-12 stopped in 1949,and as Maveric said,it was not slow,so
may be Sukhoi submitted anther proposal,and what about Yakovlev ?.

An-2F or An-2NAK / NRK - OKB-153 (Antonov) and
Su-12 or RK - OKB-134 (Sukhoi) both aircraft developed in 1946-47.


Reconnaissance aircraft development OKB-115 (Yakovlev), the period covered by the terms of reference based on the resolution "On the construction of a pilot corrective-reconnaissance aircraft and helicopters experimental series." "О строительстве опытного корректировочно-разведывательного самолета и опытной серии геликоптеров." (Order of the Ministry of Aviation Industry from August 15, 1946) - I do not know.
