There is probably no more uniquely a Soviet/Russian weapons system than the unguided rocket – think Katyusha. Their use, on a smaller scale, extended to Soviet concepts of close air support with aerial unguided rockets. Whereas in Western air forces the unguided rocket is a thing of the past in favor of precision munitions, they remain a staple with most Soviet/Russian-influenced air forces. Such is their belief in the system that the Soviet Union produced a broad array of rocket pods to accommodate their principal unguided 55mm aerial rocket, the S-5. Provided in this set is the early UB-16 without the extension tubes for the 5 interior rockets. Later UB-16s have the extension tubes. They are listed for use with the MiG-17, MiG-19, and the MiG-21, but I have also seen them carried on Syrian L-39s.
