Introduction

The 9K52 Luna-M is an early Cold War era artillery rocket system of Soviet origin. In the West the 9K52 Luna-M is known best by the NATO reporting name FROG-7. It was developed in the Soviet Union as a replacement for the earlier FROG series artillery rockets.

Layout

The FROG-7 launch vehicle is based on the BAZ-135 8x8 truck chassis. It carries a single launch rail for the 9M21 rocket and is fitted with two outriggers. The 9M21 artillery rocket is unguided and features a solid propelland rocket motor. The 9T29 transloader vehicle on the same BAZ-135 chassis carries three rockets. A fire direction vehicle based on the GAZ-66 tows a trailer mounted meteorological radar.

Firepower

The FROG-7 fires the massive 9M21 artillery rockets with various types of warhead. These are unguided and spin stabilized. The range envelope is 12 to 68 km. The accuracy is limited with a CEP of 400 to 700 meters. Preparation time before firing is 15 to 30 minutes.

Protection

The FROG-7 is based on a softskin vehicle and during firing and reloading the crew is unprotected. There is no NBC system.

Mobility

The BAZ-135 8x8 vehicle allows for a reasonable cross country performance and good road speeds.

Users

The FROG-7 was widely employed as a tactical weapon by the USSR and Eastern Europe during the Cold War. It was also exported to many allies of the USSR. Nowadays in Eastern Europe and Russia it is mostly phased out or replaced by the newer SS-21.

Variants

9K52 Luna-M

The launch vehicle of the FROG-7 or 9K52 Luna-M system is based on the BAZ-135 8x8 chassis and is called the 9P113. The launch vehicles are accompanied by a fire direction vehicle on a GAZ-66 chassis and 9T29 transloaders based on the same BAZ-135 chassis carrying three missiles each.

9P113: Transporter erector launcher (TEL) based on ZIL-135LM 8x8 truck.
9T29: Transloader based on ZIL-135LTM 8x8 truck. Carries up to three 9M21 rockets side by side. Center rocket lies horizontal. Rockets on each side are tilted slightly upwards.
9T111M: Small long wheel base trailer for a single 9M21 rocket.
