Development and Design

M60A1 Series

M60A1 (AOS)

In 1972, the M60A1 (AOS) was introduced, which gave the tank an add-on stabilization (AOS) system. It was a kit that could be applied to M60A1 tanks with very little modification to the hydraulic gun control system. The AOS allows for stabilization of the gun vertically and of the turret horizontally. This allowed the gunner to track targets and control the gun and turret while the vehicle was moving; this increased the hit-on-the-move capability significantly. Before the AOS upgrade the fire-on-the-move accuracy at 2000 meters was practically 0%, whereas with the upgrade 70% accuracy was achieved. The AOS had three modes: power-with-stabilization-on, power-with-stabilization-off, and manual. Power-with-stabilization-on was the mode which stabilized the gun, power-with-stabilization-off allowed the turret to be controlled electrically when the stabilizer was not necessary, and the manual mode allowed the crew to still traverse the turret and elevate the gun if the electrical or hydraulic systems were inoperable.

M60A1 (AOS)+

M60A1 (AOS)+ is the designation for M60A1 tanks that were equipped with the TLAC, AOS, and T142 tracks. The T142 track debuted in 1974, and it had replaceable rubber pads, improved end connectors, and had a better service life.

M60A1 RISE

M60A1 RISE+

M60A1 RISE Passive

M60A3 Series

The official full name of the M60A3 was Tank, Combat, Full Tracked: 105-mm Gun, M60A3. It was also known as the 105mm Gun Tank M60A3.

Development

During the 1970's there was a rapid advancement in anti-tank technology, and with the failure of the M60A2 program to produce a sufficient fighting vehicle an upgrade of the M60A1 series was necessary. In 1976, a program to do just that was initiated; the intention was to increase the turret armor and to modernize and improve the technological systems in the tank. The product of the program was the M60A3 tank, a significant improvement over the M60A1 series. Despite the improvement over the earlier M60 models, the M60A3 was viewed as a stop-gap measure, as the M1 Abrams was already being developed and was planned to enter service in 1981. The M60A3 eventually replaced all US Army M60A1 and M48A5 tanks (used by the National Guard until 1987) in service. But, the Marine Corps still used the M60A1 RISE tanks until the M60 was retired from front line service in 1991.

Production

In February of 1978, the first M60A3 tanks were finished at the Detroit Arsenal Tank Plant. The low-rate initial production run was completed at the DATP in October, which consisted of 296 M60A3 tanks; the tanks were first fielded by the US Army in May of 1979. Chrysler Defense was purchased by General Dynamics Land Division in 1982. In May 1983, production of the M60A3 ended with a total of 1,052 M60A3 and M60A3 TTS tanks built. At this time, the Detroit Tank Plant closed, and production of the M1 Abrams was at the Lima Tank Plant in Ohio. Despite this, the conversion of earlier M60 tanks to the M60A3/E60B standard was still occurring, specifically for other nations through the Foreign Military Sales program. The last M60A3 tanks were delivered through the FMS in May of 1986 to Israel, with a total of 3,268 tanks converted. The tanks upgraded for Israel were surplus US Army M60A1 RISE tanks. Earlier M60 tanks were also converted to the M60A3 TTS standard for the US Army. Other nations including Italy, Austria, Greece, Morocco, and Taiwan upgraded their M60s to the M60A3 standard through FMS contracts with Raytheon and General Dynamics in the 1980's. In 1990, surplus M60A3/E60B tanks were sold to Oman, Bahrain, and Saudi Arabia.

M60A3 Passive

This was the first model of the M60A3 series; it was known simply as the M60A3, but was also known as the M60A3 Passive in order to better distinguish it from the later M60A3 TTS. The M60A3 was based on the M60A1 RISE Passive tank, but with a number of upgrades for the turret - most notably changes to the armor and fire control system. The armor on the turret face was increased to 276 mm and the armor on the gun mantlet was changed to 330 mm. The M60A1 RISE Passive tanks uses a coincidence rangefinder and the mechanical M19 ballistic computer. The M60A3 received the M21 fire control system which includes an AN/VVS2 flash-lamp pumped ruby-laser rangefinder for the commander and gunner, solid-state M21E1 gun data computer, improved stabilization mechanism, improved electrical system, and an improved solid-state analog data card bus. The M10A2E3 ballistic drive is an electro-mechanical unit.The commander received an M36E1 passive periscope and the gunner received an M32E1 passive sight. The hydraulic fluid in the turret was changed to a type that was non-flammable. The M60A3 turret was mounted on the chassis of the M60A1 RISE Passive hull, with the same AVDS-1790-2D RISE engine and CD-850-6A transmission, with a Halon fire-suppression system. A total of 748 M60A3 Passive tanks were built, and all were later upgraded to the M60A3 TTS standard.

M60A3 TTS

The M60A3 TTS was an improved model of the earlier M60A3. The gunner received an AN/VSG2 Tank Thermal Sight (TTS), which was the only major improvement over the M60A3 Passive. 304 M60A3 TTS tanks were built (with production ending in 1983), 1,391 of the US Army M60A1 RISE tanks were converted to the M60A3 TTS standard by the Anniston Army Depot and Mainz Army Depot by 1990, and all 748 US Army M60A3 tanks were also upgraded to the TTS standard by 1984.

M60AX/Super M60

Development

The M60AX, commonly known as the Super M60, was an upgrade package for the M60A1 and M60A3 tanks offered by General Dynamics in 1985. It was developed as a private venture for foreign nations that already operated M60s; it was never considered for service with the US Military. The US Army decided not to develop a new power pack or suspension system for the M60, but General Dynamics formed a co-operative private venture with Teledyne Continental to do just that. Additional armor was also fitted.

Design

The M60AX was based on the M60A1 RISE hull and the T95E7 turret from the M60A1 and M60A3 series. The power pack was replaced by the AVCR-1790-1B engine and the Renk RK-304 transmission. The torsion bar suspension was replaced with the National Waterlift hydropneumatic suspension system. These upgrades increased the mobility of the tank by 20%. The protection of the vehicle was also improved with a layer of composite armor on the turret and laminate steel panels on the front of the hull. Steel side skirts were added to the sides of the tank as well, and Kevlar spall liners were added to the crew compartment. The tank kept the standard crew of 4 of the M60, with the driver in the hull and the gunner, commander, and loader in the turret.

The armament of the M60AX remained similar to that of the M60A3. The main gun was a 105 mm/L55 M68A1E2 gun; this was the same model as used on the M1 and IPM1 Abrams, which had a longer XM24 tube and a thermal sleeve when compared to the gun of the M60A3. Additionally, the coaxial 7.62 mm M73 machine gun was replaced by a 7.62 mm M240C machine gun. The commander's cupola (formerly the M19 model) was replaced with a low-profile cupola, with a pop-up hatch. A 12.7 mm M2HB machine gun was mounted on a pintle mount for operation by the vehicle commander. The fire control system (FCS) was nearly identical to that of the M60A3 TTS. It consisted of the M21E1 solid-state ballistic computer, Raytheon AN/VSG2 Tank Thermal Sight (TTS) for the gunner, a Raytheon AN/VVS2 laser rangefinder, an M10A2E3 electro-mechanical ballistic drive, and solid-state analog data card bus. No optical rangefinder was fitted to the prototype, but one could have been fitted with ease.

Production

The M60AX was one of the first private upgrade packages offered for the M60 series of tanks. Despite the largely increased capability of the M60AX when compared to standard M60 tanks, no nation bought any, and the total production remained at only 1 prototype. This may have been because there was no need at the time as the Cold War was winding down. The project was effectively over by the time the Cold War ended, as newer tanks became more widely available.

M60-2000/120S Main Battle Tank

Development

General Dynamics Land Systems (GDLS) began work on an upgrade of the M60 platform as a private venture in 1999. It was originally called the M60-2000, but the name was then changed to 120S, as the vehicle was more than just a simple upgrade of the M60. The 120 stood for the 120 mm gun, and the S stood for speed and survivability. A number of nations were briefed on the design in 2000, and a working prototype was built in 2001. The prototype was shown in Turkey at the IDEF Exhibition in October.

Design

The tank consisted of an M60A1 chassis with an M1A1 Abrams turret mounted on it, both parts loaned by the US Army. Originally, an upgraded M60A3 turret was considered, but the M1A1 turret was preferred. The M1A1 turret could be fitted to the M60 chassis by using an adapter ring; very few modifications to the turret were needed. The turret is that of the standard M1A1, and not the M1A1HA - so no depleted uranium was used in the composite armor. The armor package was customizable for the customer, and one of the options consisted of STANAG Level 6 armor plates being added to the hull front and sides up until the third road wheel. Slat or cage armor could be added to the turret, steel or composite side skirts could be added, and spall liner and ERA packages were also available. The prototype was fitted with mock side skirts lacking the protection of production side skirts; it was also fitted with new sponsons more similar visually to those on the Abrams. The 120S had a crew of 4, with the driver in the hull and the commander, gunner, and loader in the turret.

The suspension of the hull was changed to the same torsion bar suspension system as used on the M1 Abrams, in order to compensate for the increased weight. If the customer preferred, hydropneumatic suspension could be used instead.  The powerplant used on the prototype was the same as on the M60A1, the Continental V-12 750 hp (560 kW) air-cooled AVDS-1790-2 diesel engine with a CD-850-6 cross drive transmission, with a range of 275 miles. It was planned that the production vehicles would use the more powerful General Dynamics Land Systems AVDS-1790-9 diesel engine (1,200 hp) and Allison X-1100-5 series automatic giving a range of over 300 miles. Other powerplants were offered as well, and the road wheels and drive sprocket could be changed the the type used on the M1 Abrams, and the T158 lightweight track from the Abrams was also offered.

The armament of the 120S consisted of the 120 mm M256 gun with a thermal sleeve; this was the exact same as on the M1A1 Abrams. 36 rounds were carried in the turret bustle rack with blowout panels for increased survivability. It was planned that there would be additional ammunition stowage in the floor of the hull for production models. The secondary armament consisted of a coaxial 7.62 mm M240C machine gun, a 7.62 mm machine gun mounted on the loader's hatch, and a 12.7 mm M2HB machine gun mounted on the commander's hatch. Two M250 smoke grenade launchers are carried, one on each side of the turret. Each launcher has six barrels for smoke grenades. Not only do the smoke grenades visually conceal the tank, but they also conceal the thermal signature of the vehicle. The tank is also capable of using a vehicle engine exhaust smoke system , which creates smoke by spraying oil on the engine. The tank was equipped with a 240X4 Forward Looking Infrared Radar (FLIR), day/FLIR stabilized sight with an eye-safe laser range-finder, a thermal imaging system, and an onboard digital fire control computer and data bus similar to the M1 Abrams Mark 1 Advanced Fire Control System.

Production

The 120S was mainly marketed to Turkey in order to fill their M60 upgrade requirements, but that contract was won by Israel Military Industries with the Sabra III upgrade. The Egyptian Army considered the 120S upgrade, but decided to license-build M1 Abrams tanks instead. In total, only one prototype was completed, and the 120S never entered production. The prototype was disassembled and both parts were returned to the US Army in 2003. The 120S is no longer being marketed by General Dynamics.

M60A3 SLEP

In May 2016, Raytheon offered the M60A3 Service Life Extension Program (SLEP). The SLEP was designed for export to current M60 operating nations, in order to allow for an upgrade of the M60s used by those nations as a cheaper alternative to buying a fleet of newer tanks. The SLEP is a multiple of modular upgrades to the M60 that cover mobility, armor, and firepower. The modularity of the components allow customization for the needs of each country.

The main armament was upgraded to the 120 mm M256 L/44 gun, the same gun as used by the M1A1 Abrams. A fire rate of 6 to 10 rounds per minute with the load assist system. The Integrated Fire Control System (IFCS) was added. The IFCS consisted of a laser rangefinder, second generation night sight for the gunner, digital ballistic computer, cant sensors, electrical superelevation resolver, and MIL-STD 1553 data bus. Additionally, the Curtis-Wright Gun Turret Drive was added, and the M19 commander's cupola was replaced with the Hitrole remote controlled weapon system, which allowed the commander to view the surrounding are from inside the tank, via the .50 cal M2HB machine gun. The engine was replaced with a 950 hp AVCR-1790-2C engine, and the suspension was improved. An Automatic Fire and Explosion Sensing and Suppressing system (AFSS) was added. Slat armor was added to the turret bustle, to protect against RPG and ATGM attacks, and armor plates rated at STANAG 4569 Level 6 protection were added to the front of the vehicle. The finished vehicle weighed about 63 tons.

Leonardo M60A3

The Leonardo M60A3 was unveiled in October 2017 by Leonardo DRS at the Bahrain International Defense Exhibition and Conference (BIDEC). It is intended as an alternative to the M60A3 SLEP upgrade program in order to allow nations using the M60 to bring their tanks up to more modern standards.

The upgrade consists of thorough modernization throughout the different parts of the tank. The 120/54 gun from the Centauro II/MGS is used instead of the 120 mm L/44 gun, in order to reduce the weight by 500 kg. The M19 commander's cupola was replaced with an armored circular cupola protected with slat armor; the new cupola has a much lower profile than the M19 model, and it also weighs less. A HITROLE-L 12.7 mm remote weapons station has been added to the loader's side of the turret roof. The turret was upgraded with a new hydraulic and servo control system, which improves the reliability and performance of the turret. The tank comes equipped with the LOTHAR gun sight, DNVS-4 Driver's Night Vision Sight and TURMS digital fire control system. A daytime thermal camera and an eye-safe laser rangefinder are equipped.

The armor of the tank has also been substantially upgraded. Passive armor protection claimed to meet STANAG Level 6 protection standards has been added to the turret and hull. The armor is focused on the front of the turret in order to protect against chemical rounds, and it is also applied to the front of the hull and the hull sides until the third road wheel. Slat armor was added to the back of the turret, in order to protect against RPG attacks. If the client requests, IED jamming systems and a laser warning receiver can be fitted.

The powerplant can either be refurbished or replaced with an improved version. The improved powerplant consists of the  AVDS-1790-5T 908 hp engine (replacing the old 750 hp engine) and the CD-850-B1 transmission. The tank is fitted with the Automatic Fire and Explosion Sensing and Suppression System (AFSS). Additionally, the torsion bar suspension, brakes, fuel supply, electric system, wheels, seals, paint, and smoke grenades were all changed and improved.
