122 mm 9M22K Grad rocket
Also known as
- 9M22K
- 122 mm 9M22K
- 122mm 9M22K Grad rocket
- 9M22K2
The 122 mm 9M22K is a Soviet/Russian Grad-family submunition carrier rocket for the BM-21 launcher. CAT-UXO and GICHD identify 9M22K as a Grad delivery round associated with PTM-3 scatterable anti-vehicle mines, while U.S. Army OE Watch groups the closely related 9M22K2/9M28K mine rocket as the BM-21's three-mine remote-mining option.

Variants
Public technical references do not use the Grad mine-rocket designations uniformly. The CAT-UXO/GICHD 9M22K identification is best read alongside adjacent 9M22K2 and 9M28K references, without treating PTM-3 use reports as exact 9M22K conflict-use evidence.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Adjacent Grad mine-laying rocket | Missilery lists the 9M28K among Grad ammunition as a cassette round fitted with anti-tank mines. |
Launch Platforms
CAT-UXO and GICHD identify the 9M22K as a Grad-family mine-delivery rocket for the BM-21 launcher, while OE Watch discusses the closely related 9M22K2/9M28K designation pair in the same launcher role.
| Launcher | Launcher type | Launch evidence |
|---|---|---|
 | 122 mm multiple rocket launcher | CAT-UXO places the 9M22K in the BM-21 Grad rocket family; GICHD also lists 122 mm Grad as a PTM-3 delivery route. Sources: CAT-UXO 122mm 9M22K Grad rocket, GICHD Explosive Ordnance Guide for Ukraine |
Designation And Payload Notes
Public references connect 9M22K to PTM-3 delivery, but they do not all draw the same boundary between 9M22K, 9M22K2, and 9M28K.
| Reference point | What it supports |
|---|---|
| 9M22K page scope | CAT-UXO identifies the 122 mm 9M22K as a BM-21 Grad rocket with PTM-3 anti-vehicle mine payload, base ejection, electrical initiation, and fin/spin stabilization. |
| PTM-3 delivery path | GICHD lists PTM-3 as a scatterable magnetic-influence anti-vehicle mine that can be dispensed from 122 mm Grad 9M22K, 220 mm Uragan 9M59, and 300 mm Smerch 9M55K4 launch routes. |
| Adjacent designation | OE Watch describes the BM-21 as capable of firing 9M22K2/9M28K scatterable mine rockets, each carrying three PTM-3 mines. |
| Conflict-use caution | Landmine Monitor documents PTM-3 antivehicle mines in Ukraine, but that mine-monitoring source does not identify the 9M22K rocket as the delivery munition. |
Timeline
122 mm 9M22K Grad rocket Key Events
Grad system accepted for Soviet service
Missilery's Grad history cites the Soviet decision accepting the M-21/9K51 Grad field rocket system, the launcher family later associated with 122 mm mine-laying rockets.

OE Watch highlights BM-21 remote-mining limits
U.S. Army OE Watch described the BM-21 as capable of firing 9M22K2/9M28K scatterable mine rockets but noted the three-mine payload makes large minefields inefficient compared with larger Uragan and Smerch mine rockets.

Mine monitors list PTM-3 in Ukraine
Landmine and Cluster Munition Monitor lists PTM-3 antivehicle mines among landmine types used in Ukraine, but it does not identify 9M22K as the delivery munition for those cases.
