M109 SPH

The M109 is an American 155 mm turreted self-propelled howitzer (SPH), first introduced in the early 1960s. The M109 family is the most common western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions.

The newest M109 version for U.S. service is the M109A7, formerly known as the M109A6 Paladin Integrated Management (PIM). The M109A7 shares common components with the Bradley Fighting Vehicle (BFV) such as the engine, transmission, and tracks.

Weighing 78,000 lb (35,000 kg), the M109A7 is 10,000 lb (4,500 kg) heavier than its predecessor, and it has the capacity to grow to 110,000 lb (50,000 kg). Even with the weight increase, the M109A7 can travel faster than previous versions at 38 mph (61 km/h) and is more maneuverable than a Bradley Fighting Vehicle. The M109A7 can sustain a one-round per-minute rate of fire and a maximum rate of fire of four rounds-per-minute.

A crew of four Soldiers operates the SPH and can use it to engage targets at ranges of 22 kilometers using standard projectiles and 30 kilometers using rocket-assisted projectiles.


The M992A2 Field Artillery Ammunition Supply Vehicle (FAASV) is built on the chassis of the M109-series howitzer. It is also colloquially referred to as a “cat” (referring to its nomenclature, CAT: Carrier, Ammunition, Tracked). It replaced the M548 supply vehicle. Unlike the M548, it is armored.

This ammunition vehicle has no turret, but has a taller superstructure to store 95 rounds with a corresponding number of powders and primers. There is a maximum of 92 conventional rounds, 45 each in two racks, and 3 M712 Copperhead rounds.
