Features:
The M198 Medium Towed Howitzer is a 155mm field
artillery howitzer. It is constructed of aluminum
and steel, and is air transportable by CH-53E
helicopter, and C-130 or larger fixed-wing aircraft.
The M198 provides increased range, and improved
reliability and maintainability over the former
standard towed 155mm howitzer, the M114A2. The use
of rocket-assisted projectiles significantly extends
the range, lethality, and counterbattery fires of
the direct support artillery battalions. The M198
fires all current and developmental 155mm
ammunition.
Background: The first 10 M198 Howitzers
were delivered to the 10th Marine Regiment in
January 1982. The first Army M198 Howitzers were
delivered to Ft. Bragg.
