The 9M55K4 is a Russian 300 mm Smerch rocket for remote laying of anti-tank minefields from the BM-30 / 9K58 launcher family. Rosoboronexport lists it as a 25-mine PTM-3 delivery round, while GICHD and U.S. Army T2COM describe the same Smerch/PTM-3 combination in explosive-ordnance and Russian remote-mining context.
The 9M55K4 belongs to the Smerch mine-laying rocket subfamily and is closely related to the 9M527 anti-tank mine rocket designation.

The 9M55K4 is a Smerch-fired 300 mm rocket for remote laying of anti-tank land mines.
| Launcher | Launcher type | Launch evidence |
|---|---|---|
![]() | 300 mm multiple launch rocket system | Rosoboronexport lists the 9M55K4 as a 300 mm rocket for the Smerch multiple launch rocket system, and GICHD identifies the 9M55 series as launched by the 9K58 Smerch / BM-30 family.

The 9M55K4 changes a Smerch launcher from an area-fire rocket system into a remote anti-tank minefield delivery system. The key relationship is between the 300 mm rocket body, the BM-30 / 9K58 launcher, and the PTM-3 scatterable mine payload.
| Feature | 9M55K4 detail | Reader context |
|---|---|---|
| Launcher connection | Rosoboronexport lists the rocket for the Smerch multiple launch rocket system, and GICHD identifies the 9M55 series as launched by the 9K58 Smerch / BM-30 family. | The munition is not a separate launcher; it is a Smerch round that gives the launcher a remote mining role. |
| Mine payload | Rosoboronexport, GICHD, and T2COM all identify a 25-mine PTM-3 anti-tank or anti-vehicle mine payload. | One full 12-rocket Smerch salvo could disperse a large anti-vehicle mine load, though exact minefield geometry depends on firing method and conditions. |
| Mine behavior | GICHD describes the PTM-3 as a scatterable magnetic-influence anti-vehicle mine, and Rosoboronexport lists a 16-24 hour self-destruction time for the mine payload. | The payload is intended to obstruct or channel armor rather than produce an immediate blast-fragmentation strike like other 9M55 warheads. |
| Russian remote-mining context | T2COM identifies BM-30 Smerch with 9M55K4 as one of the practical Russian MLRS combinations for deploying PTM-3 mines at distance. | The designation links launcher, rocket, and scatterable mine functions in one remote-mining package. |
