The M77
Oganj (fire) multiple launch rocket system was developed in
Yugoslavia in the late 1960s. Its prototype was first publicly
revealed in 1975 and production commenced in 1980s. This artillery system saw
action during the Yugoslav wars. Currently Serbian Army operates
about 70 of these systems. A small number might also be in service
with other former-Yugoslavia countries.
The M77
Oganj has 32 launching tubes for 128 mm rockets. It fires warheads
with anti-tank or anti-personnel submunitions. Maximum range of fire
is 20.6 km. A full salvo of this rocket system covers area of 0.36-1.1 ha, depending on the warhead
type. It can also fire Serbian newly
developed Grad-M and Grad-2000 rockets with improved range and firepower.
The M77
Oganj MLRS is mounted on the
FAP 2026 6x6 truck. A 12.7 mm
heavy machine
gun is mounted on top of the roof for self-defense. Vehicle is
fitted with a central tyre inflation system.
Vehicle
carries a full set of reload rockets, stored behind the cab in the
automatic loader. It speeds up reloading process, however this
rocket system can also be reloaded manually. The M77 Oganj can
launch two sets of rockets from traveling and leave firing position
within 6.5 minutes. In traveling position rocket launcher is covered
by hydraulically operated canvas cover, which makes it hard to
recognize, as vehicle looks like an ordinary utility truck.
Variants
Oganj 2000
ER, a recently developed 122 mm rocket system, based on the Russian KamAZ 8x8 truck. It has 50 launching tubes and carries another 50
reload rockets.
