M48A2

Design

The engine deck was redesigned; the grills were replaced with two large louvered doors, which helped to cool the engine more efficiently and also reduce the infrared signature of the vehicle. The suspension system was also modified, in order to simplify construction. They removed the track tensioner arm, modified the idler arm, added bumper springs and friction snubbers, and the air cleaning assembly was moved. The number of return rollers per side was changed from five to three. The engine was changed to the AVI-1790-8, which was more compact, but gave slightly more horsepower. The more compact engine allowed for the installation of additional fuel tanks, causing an increase of fuel carrying capacity, to 335 gallons. M48s and M48A1s were upgraded to the M48A2 standard, so many M48A2 retained the five return rollers.

M48A2C

The M13 Fire Control System was added, with the M5A2 ballistic drive and the M13A3 gun data computer, along with the M17 coincidence rangefinder which replaced the M12 rangefinder on previous M48s. The M13A3 gun data computer added gun barrel distortion to the calculations, and the M17 rangefinder was a double image coincidence image instrument. The gunner received an M20 day periscope with 8x magnification and an M105D day telescopic sight with 8x magnification and a 7.5 degree field of view.

M48A3

Development

The gasoline engine used on earlier M48 models proved to be unreliable, and was also known for catching on fire. Continental Motors and OTAC had been developing an X-shaped compression ignition engine in 1954, using the T95 to test it, but it proved to be unreliable. OTAC was instructed in June, 1955 to use a diesel engine if it was more fuel efficient. The AVDS-1790 diesel engine was selected in August, 1956, and in December the Army ordered 1,020 M48A1 and M48A2 to be converted to use the new engine.

A Soviet T-54 tank was driven onto the UK's embassy in Budapest's property during the Hungarian Uprising in 1956, and it was inspected by a British military attaché. They found that the British 20 Pounder would be unable to penetrate the frontal armor, and the 100 mm was extremely capable, and it was even suspected the Soviets were working on a larger 115 mm gun. The US Army was quick to act, and started to develop the XM60 medium tank and the M68 105 mm gun, in order to replace the M48 series.

Design

The M48A3 was the first M48 to incorporate a diesel engine, the AVDS-1790. This solved the problem of the engine catching on fire, and increased reliability. The commander's M1 cupola was modified to the M1E1 cupola, which removed the two rear vision blocks and modified the hatch, to increase the room inside the cupola. The M48A3 tanks that were built used the M48A2 hull (three return rollers), but many M48A1 and M48A2 were converted to the M48A3 standard. Some modifications were made to the hull: the steering wheel used by the driver was changed to a T-bar control, the driver received a padded seat, new fenders and mudguards were added, armored boxes were added around the taillights, and other minor details. As the M48A3 was a modification of previous models, the M48A3 had a number of varying characteristics. For example, the M48A3 could have either three or five return rollers, earlier or later headlight layout, and the M48A3 could also have the earlier M1 cupola.

M48A5

The M48A5 upgrade was applied to National Guard M48A2s and M48A3s, along with some M48A1s in order to maintain ammunition commonality between the tanks. The main feature of the upgrade was the change in main armament to the M68 105 mm gun, using the M116 mount and an all-metric measurement M16 fire control system. The hull featured components from the M60A1 RISE Hull PIP Update Kit, in order to increase commonality. The most notable component from the RISE was the AVDS-1790-2C engine with TLAC engine panels. The transmission was changed to the CD-850-6 cross-drive transmission, used the T142 track assembly, and got the M13A1 NBC protection system. The co-axial .30 cal M37 machine gun was replaced with the .50 cal M219/T175 machine gun. As the M48A5 was an upgrade of multiple earlier models, it had many different variations. One example of this being the return rollers; the M48A5 could have either three or five return rollers. The M48A5 could also have differences in the headlights layout, with either the early layout or later layout. Additionally, some M48A5s had earlier cupola styles.

M48A5API

The Israeli military had received M48 Patton tanks, and replaced the M1 cupola with an Urdan cupola, which featured a low profile. The Urdan cupola did not allow the commander to fire his machine gun from inside the tank, but gave him more protection from enemy tank shells. The Urdan cupola was equipped with an M60D machine gun, replacing the previous .50 M2 Browning machine gun. Additionally, a second M60D machine gun was fitted to the turret roof, near the loader's cupola, allowing the loader to fire a machine gun. The ammunition stowage was modified, and the tank could carry 54 rounds of 105 mm ammunition. These tanks were called M48A5API, but as earlier M48A5 tanks were upgraded to the API standard they simply became known as M48A5, dropping the API designation.
