Uragan-5B / Smerch / Smerch-A Radars

[overscan (PaulMM)]

I've not read a complete account of how Uragan-5B led to Smerch radar, but it seems that in 1958 OKB-15 (later, NIIP) basically got put onto the SA-6 GAINFUL (Kub) project and part of the Uragan-5B team were transferred to Experimental Design Bureau No 339 (NIIR) where all airborne radar work became concentrated. The RP-S "Smerch" was initially called "Uragan--5B-80" with the -80 referring to the K-80 AAM.


The airborne radar teams were essentially split out of NII-17 and then recombined into NIIR. It seems the two teams continued to work somewhat separately under Volkov (Uragan-5B, Smerch, Sapfir-21, Taifun) and Kunyavsky (Sokol, Orel, Sapfir-23)
