The 2P25 launch vehicle is the tracked firing vehicle for the Soviet 2K12 Kub / SA-6 Gainful system. It sits in the catalog as a component page: the vehicle carries and launches three 3M9 missiles from a GM-578 tracked chassis, with engagement control supplied by the Kub radar/control element rather than by the launcher alone.
The launcher designation follows Kub-system modernization rather than a separate stand-alone weapon family; public references identify modernized 2P25M1 launchers in Kub service while SPU is used as launcher terminology.
The launcher is documented as the tracked firing element inside the Kub family rather than a stand-alone missile system.

The 2P25 is documented as the launch vehicle inside the 2K12 Kub / SA-6 system, not as a complete fire-control system by itself. Its page therefore links the launcher to the parent Kub system and to the 3M9 missile it carries.
| Catalog item | Component role | Source-supported context |
|---|---|---|
| Parent SAM system | Kub batteries combine 2P25 launch vehicles, 3M9 missiles, and 1S91 radar/control vehicles for medium-range air defense. |
| Carried missile | Each 2P25 launch vehicle carries three ready 3M9 missiles on the tracked launcher chassis. |
