The SA-3 'GOA' is not a new missile, after all, the SA-2 'GUIDELINE' before it has been around for decades. These missiles have been continuously upgraded over the years, though- and one of these brought down a F-117A Stealth Fighter over Serbia.

This is a re-loader. It brings a pair of missiles, and offloads them backwards onto an SA-3 Twin launcher. A really essential piece of equipment.
