Introduction

The M59 is an armored personnel carrier of US origin. It was developed in the early 1950's as a cheaper and more mobile follow on to the M75 that entered US service only a few years earlier. Although the M59 was plagued by a limited reliability large numbers were produced before the successful M113 entered service.

Layout

The design of the M59 is roughly based on the earlier M75. The M59 features a new chassis, has thinner armor and a lower profile. Instead of a single engine two smaller and cheaper engines are used. However the mechanism to combine the power from both engines proved unreliable. The troop compartment is at the rear and is accessed by a single door. A trim vane is located on the bow and is used during amphibious operations.

Firepower

The M59 is armed with a single 12.7mm M2HB heavy machine gun in a low profile turret. The advantage over the ring mount of the M75 is the armor protection for the gunner, but situational awareness is reduced and the weapon is harder to aim. A mortar carrier with the 107mm M30 mortar was also produced.

Protection

The steel armor protects the crew from small arms fire and shell splinters. Since the armor is rather thin armor piercing rounds will easily penetrate. An NBC system and smoke grenade dischargers are both lacking.

Mobility

The tracked chassis allows the M75 to cross allmost any terrain. Although the weight has been reduced while a similar power is retained the M59 does not have a better mobility than the M75. In fact it has a lower top speed and very limited operational range. The major improvement over the M75 is the amphibious capability.

Users

The main user of the M59 was the US army. Large numbers were acquired and used until the mide 1960's. In US service the M59 was replaced by the much more capable M113. When the M59 was replaced large numbers of ex-US army M59's were exported to various allies of the USA. Nowadays the M59 is obsolete and no longer used.

Variants

M59

The M59 is an armored personnel carrier that was produced only in one version. It can be distinct from the M113 by its horizontal bow, forward location for the M2HB cupola and single rear door.
