R-5B rocket (R-5BA, V-5B) - Soviet single-stage liquid geophysical rocket .
Creation History
It was created on the basis of the R-5M medium-range ballistic missile developed under the guidance of S.P. Korolev in OKB-1 .
The R-5B rocket was designed to continue scientific research and study the upper atmosphere associated with flights at high speeds and altitudes of the order of 500 km. The decision to make five copies of the rocket was made on February 23, 1960 .
R-5B significantly differed from the R-5A missile in a set of scientific experiments related to promising developments of OKB-1 . The new missile had an inseparable warhead with a set of research facilities that had individual rescue systems.
There were two options for manning the head of the equipment - R-5B (two missiles) and R-5BA (three missiles).
All missiles of this type also included studies of the parameters of the upper atmosphere, the circulation processes in the stratosphere, the parameters of the ionosphere, the nature of the phenomena caused by the corpuscular radiation of the solid component of interplanetary matter, the Earthβs magnetic field.
In total, from the Kapustin Yar training ground between October 18, 1962 and July 6, 1963, five R-5B missile launches were carried out.
