Vulkan M-92 - Mobile Multiple Rocket Launcher That Fires 122 mm Rockets Up to 12 miles.

The Vulkan M-92 is a mobile multiple rocket launcher that fires 122-mm rockets, capable of engaging targets up to 12 miles.
Development of this system began in 1968. The mechanical engineer and Chief Operating Officer of the Artillery Department of the Military Engineering Institute, was responsible for overseeing its development and production.
The six pre-series production models were based on the FAP 2220 6x6 truck and were shown to the public for the first time in 1975. Serial production began two years later. Serial production variant mounted on a FAP 2026 BDS/A 6x6 truck body. The rocket system is placed at the rear of the platform and contains 32 128mm launch tubes capable of hitting targets as far as 20.6 kilometers (12.8 miles).
This system is operated by five personnel. One of its unique features is its retractable canvas, which allows the rocket launcher to be easily disguised and makes it difficult for the enemy to recognize it until the crew is ready to fire.
In 1994, Serbia developed a new version called the M-94 Oganj C, which could fire M91 (cluster-type warhead with 40 grenade submunitions) and M77 (HE warhead) rockets. This version features a 32-rocket reloading system that allows for a complete reload and launch of a second salvo within three minutes.
