The M224 60 mm Lightweight Mortar is a smooth bore, muzzle-loading, high-angle-of-fire weapon used for close-in support of ground troops. It was deployed extensively in the War in Afghanistan by the United States military.

Description

The M224 system is composed of these parts:

  • M225 Cannon: 14.4 lb (6.5 kg)
  • M170 Bipod: 15.2 lb (6.9 kg)
  • M7A1 Baseplate for use in conventional mode: 9.6 lb (4.4 kg) or
    • M8 baseplate for use in handheld mode: 3.6 lb (1.6 kg)
  • M64A1 Sight Unit (The M67 Sight Unit is now widely used for the system): 2.5 lb (1.1 kg)

The mount consists of a bipod and a base plate, which is provided with screw type elevating and traversing mechanisms to elevate/traverse the mortar. The M64A1 sight unit is attached to the bipod mount. The mortar can be fired in the conventional mode or the handheld mode. This smooth-bore system can be gravity-fired or fired by using a manual spring-loaded trigger.

It is typically fielded at the infantry company level. A small mortar section with two mortars was organic to Army rifle companies (light, airborne, air assault) and Ranger companies. Marine rifle companies have a section with three 60mm mortars in the company weapons platoon.

History

The M224 LWCMS (Lightweight Company Mortar System) replaced the older (WWII-era) 60 mm M2 Mortar and M19 Mortar and began fielding in the mid-1970s. These weapons had an effective range of only 2,000 m (2,187 yd). While the M224 was designed to fire all types of the older ammunition, its primary rounds are of the newer, longer-range type that range out to 3,489 m (3,816 yd).

In 2011, an improved M224A1 version was brought into service.[3] The M224A1 consists of the M225A1 tube, M170A1 bipod assembly, M7A1 baseplate, M8 auxiliary baseplate and the M64A1 sight unit.[3] By reducing the number of components and using lighter materials the mortar system weighs 20% less with a reduction of 9.3 lb (4 kg).[3] The US Army plans to replace all legacy M224s with the new M224A1.[3] Concurrently, a lighter version of the 81mm M252 mortar was also developed.[citation needed]

Ammunition

The M224 Mortar can fire the following principal classifications of training and service ammunition:

  • High explosive (HE): Designations M888, M720, and M720A1. Used against personnel and light material targets.
  • Smoke Cartridge (WP): Designation M722. Used as a screening, signaling, or marking munition.[5]
  • Illumination (ILLUM): Used in night missions requiring illumination for assistance in observation.
  • Training practice (TP): Designation M50A2/A3. Used for training in limited areas. These rounds are obsolete and no longer used.
  • Red Phosphorus: Can be seen with or without a Night Vision Optic.
  • Full Range Practice Cartridges (FRPC): Designation M769. This round is used for practice or clearing misfires.
  • M1061 MAPAM: SAAB Technologies produced Multi-Purpose Anti-Personnel Anti-Material round.

Fuzes

The M224 rounds have three fuze types: The Multioption Fuze (M734), the Point-Detonating Fuze (M525), and Timer fuze. The M734 is used for the M720 HE round and can be set to function as proximity burst, near-surface burst, impact burst, or delay burst.
