• 8K72 - used to launch the early Luna spacecraft and the prototype Vostok spacecraft

• 8A92 - used for launching Zenit reconnaissance satellites throughout the 1960s
• 8A92M - modified version for launching Meteor weather satellites into high orbits.

On March 18, 1980 a Vostok-2M rocket exploded on its launch pad at Plesetsk during a fueling operation, killing 48. An investigation into a similar -- but avoided -- accident revealed that the substitution of lead-based for tin-based solder in hydrogen peroxide filters had resulted in the breakdown of the H2O2 and the resulting explosion.
