The merged VKS divides into three main components — the "layers" around which this learning environment is built:
VKS — Russian Aerospace Forces
± 165,000 personnel · central command in Moscow
1 · Air Force (VVS)
The flying part: fighters, bombing, ground attack, transport, reconnaissance. Organised into 5 tactical commands (AFADA) + Long-Range Aviation (LRA) + Transport Aviation (VTA).
2 · Aerospace & Air Defence (ADD / PVO-PRO)
Ground-based air defence: the radar network (radio-technical troops), surface-to-air missiles (S-400, S-300, Buk, Pantsir) and missile defence around Moscow (A-135/A-235).
3 · Space Forces (KV)
Launch and operation of military satellites, space surveillance and the early-warning system against ballistic missiles (SPRN).
The first two components are the most important for the air-combat analyst and are covered in detail. The space component is treated briefly.
