 By 1959 Soviet scientists and engineers developed new technology, and as a result, the "Southern" design office (KBYu – as abbreviated in Russian) started a new machine-building project making ballistic missiles.Under the leadership of Yangel, KBYu produced such powerful rocket engines that the range of these ballistic missiles was practically without limits.During the 1960s, these powerful rocket engines were used as launch vehicles for the first Soviet space ships.
