M60 tank - ...ПРОДОЛЖЕНИЕ

M60A3 series

Development
Due to the rapidly developing advancements in anti-armor capabilities and solid-state electronics of the 1970s, along with the general dissatisfaction of the M60A2, an upgrade of the M60A1 was needed. In 1976 work began on the M60A3 variant which featured a number of technological enhancements.
Features
The M60A3 version of the M60-series had the same mobility, performance, and weapons systems as the M60A1 RISE and RISE Passive tanks and incorporated all of their engineering upgrades, improvements and capabilities.
The electronics and fire control systems were greatly improved. The turret's hydraulic fluid was replaced with a non-flammable one. This updated turret configuration was mated to the M60A1 RISE hull using the AVDS-1790-2D RISE engine and CD-850-6A transmission along with a Halon fire suppression system. It was designated as the Tank, Combat, Full Tracked: 105 mm Gun, M60A3.
The M60A3 tank was built in two configurations. The earlier version, sometimes referred to as the M60A3 Passive, uses the same passive gunner's sight as the A1 RISE Passive and the latest version has a Tank Thermal Sight (TTS). The M60A1, RISE, and RISE Passive tanks used a coincidence rangefinder and the mechanical M19 ballistic computer. The M60A3 uses a laser based rangefinder and the solid state M21 ballistic computer.
The M21 FCS for the M60A3 was made up of a Raytheon AN/WG-2 flash-lamp pumped ruby-laser based range finder, accurate up to 5000 meters for both the commander and gunner, a solid-state M21E1 gun data computer incorporating a muzzle reference sensor and crosswind sensor, ammunition selection, range correction and superelevation correction were inputted by the gunner, an improved turret stabilization system along with an upgraded turret electrical system and solid-state analog data card bus. The M10A2E3 ballistic drive is an electro-mechanical unit.
The commander had an M36E1 passive periscope and the gunner an M32E1 passive sight. The TTS configuration replaced the gunner's sight with the Raytheon AN/VSG2 Tank Thermal Sight (TTS), a Mercury-Cadmium-Telluride (HgCdTe) IR detector. This sight allows the gunner to see through fog, smoke and under starlight conditions without the aid of an IR searchlight. This system provided improved night fighting capabilities.
The first M60A3s were assembled at the Detroit Arsenal Tank Plant in February 1978, where the first of a low-rate of initial production quantity of 296 M60A3s were produced through October with fielding to Army units in Europe starting in May 1979. The M60A3 was seen by the US Army as a stop-gap measure as the development of the XM1 Abrams MBT was already well advanced with fielding to Europe planned to start in 1981 and notified Foreign Military Sales (FMS) customers of its near-term plans to discontinue M60-series tank production.
In March 1982 General Dynamics Land Systems purchased Chrysler Defense. The procurement of M60A3 and M60A3 TTS tanks for the Army concluded and hull production ceased in May 1983, with a total of 1,052 M60A3 and TTS tanks built as new vehicles. However the conversion of earlier models to M60A3/E60B tanks continued for FMS, with the last tanks delivered to Israel in May 1986 and a conversion total of 3,268 E60Bs. These late-production examples were upgraded from existing surplus inventories of M60A1 RISE tanks.
The Army also increased its M60A3 TTS fleet through the M60A1 Product Improvement Program (PIP) and the M60A3 tank field retrofit program conducted by the Anniston Army Depot and the Mainz Army Depot (MZAD). Depot field teams retrofitted all of the Army's 748 M60A3 tanks to the TTS configuration by the end of 1984. In addition, both depots converted a total of 1,391 M60A1 RISE tanks to the M60A3 TTS. These M60A1 RISE PIP conversion programs concluded in 1990.
Italy, Austria, Greece, Morocco, Taiwan and other countries upgraded their existing fleets with various E60B component upgrades under several FMS defense contracts with Raytheon and General Dynamics during the mid to late 1980s. In 1990, M60A3/E60Bs from Army surpluses were sold to Oman, Bahrain, and Saudi Arabia.
The M60A3 replaced the M60A1 in the US Army and any remaining M48A5s in ARNG service on a one-for-one basis. The Marine Corps continued to use the M60A1 RISE Passive until they were withdrawn from combat use in 1991. They were phased from ARNG service between 1994 and 1997, being replaced with the M1 MBT. The Detroit Tank Plant was closed in 1996 with production of the M1A1 Abrams continuing at the Lima Tank Plant in Ohio.
E60 series
M60s for use in foreign military service were designated as the E60 series by the US Foreign Military Sales (FMS). These were essentially M60s with minor modifications requested by approved foreign purchasers. Some of the modifications included removal of the M19 cupola, different models of machine guns, electronics, fire control systems or radios, external armor plates, smoke launchers and power packs. Israel purchased many of these tanks forming the basis for the Magach 6 series.
This series included the following designations:
 - E60: modified M60 variant for non-US service
 - E60A: modified M60A1 variant for non-US service
 - E60B: modified M60A3 variant for non-US service
The M60A2 was never approved for foreign sales.

Army National Guard evaluations

M60AX
Priority in initial M1 Abrams unit allotments was given to Active Army armored units in Europe. The Army National Guard's armored assets were key strategic elements, approximated at 3,000 tanks, and were important for reinforcing Active Army units in Europe in case of conflict. (This was particularly critical to the ARNG 86th Armor Brigade.) Without an inventory available to provide the ARNG with M1 Abrams tanks, unfunded Requests for Proposals (RFPs) were circulated by the ARNG Tracked Vehicle Task Force starting in 1983. Teledyne Continental developed the first RFP upgrades to the suspension, power pack and transmission. It was demonstrated and tested at Fort Knox in January 1985. The upgrade was not evaluated for US military service or assigned a designation. GDLS acquired Teledyne and by 1987 had pursued the RFP improvement to the armor, mounted the M68A1, and called it the Super 60. It was the reference point for the ARNG upgrade decisions submitted to the Department of the Army to upgrade its M60A3 TTS fleet. In the actual report, the upgrade is referred to as the M60AX. $90 million was requested for prototyping and $2.8 billion to complete the fleet conversion by 1999.
M60A4
The M60A4 was the proposed prototype upgrade of the M60A3 TTS for the National Guard that emerged from the M60AX study conducted by the ARNG Tracked Vehicle Task Force with a projected cost of $750,000 per tank. The upgrade would have included improved protection, automotive performance and combat effectiveness, but retained the same M68E1 gun as the M60A3. After examining more than two dozen possible upgrade components for the M60A3 TTS, the task force decided on the 15 subsystem upgrades that made up the M60A4 overhaul. Since the M60AX evaluation vehicle was not in the US Army Logistical system the requested components for the upgrade were inferred to by FSCM part numbers. Survivability upgrades included both appliqué and wraparound armor, internal spall liners, laser protection, an automatic fire suppression system, an engine smoke generation kit and a new low-profile cupola. Mobility enhancements included a new 1050 horsepower engine, a new automatic transmission, improved final drives, an improved vehicle suspension and a modification to the air cleaner. The M60A4's key target acquisition and fighting improvements were an upgraded laser rangefinder, an enhancement of TTS optical performance, a modified fire control system and an improved turret drive and stabilization system. After reviewing the proposal it was declined by Chief of Staff of the United States Army General Carl E. Vuono in 1988. The prototype was never constructed.
The US Army did not view the M60A4 as a cost effective proposition for the National Guard with only a limited increase in crew survivability and the same firepower as the M60A3. The M60 tank was superseded in ARNG service by the M1 version of the Abrams tank beginning in 1990. The M60A3 was phased out from ARNG service and was fully replaced by the M1A1 by 1997. Most of the M1 Abrams tanks were upgraded to the M1A1 configuration.
Foreign upgrades
A US Congressional Report in November 1993 stated that there were 5,522 serviceable M60A1 and M60A3 tanks in the US Army's inventory available for sale or transfer to US allies or foreign nations. Of these 111 were in Korea, 1,435 were in Europe, and 3,976 located in CONUS. The average age of these tanks was 16 years and an expected peacetime service life of 20 years. The average price was US$212,898 per tank as is, without radios or machine guns and they were not mechanically overhauled. Tanks located in Korea were inspected and sold to Bahrain and Taiwan.
Of the 1,435 tanks in Europe, 1,311 have been cascaded to other NATO countries under the terms of the Conventional Forces Europe Agreement (CFE), 18 reserved for non-combat use and 106 returned to CONUS. Egypt inspected 411 tanks at Fort Hood and 91 at Fort Knox and tentatively selected 299 of those. An additional inventory of tanks from the CONUS M60 fleet were available at the same unit price for other approved purchasers.
The United States chose not to pursue further upgrades to the M60 tank series after 1978. Its near-term replacement by the Army with the M1 MBT were scheduled to start production in 1980. M60 series tanks were phased out of US service by 1997 and Opposing Force (OPFOR) training use in 2005. Together with the large number of M60 MBTs still in foreign service and a large US Army surplus inventory, several upgrades for the tank were offered starting in 1985.
There are three basic approaches to upgrade decisions for the M60 MBT. Some countries, such as Taiwan and Jordan, have sought to modernize the M60 as a frontline MBT. Turkey is seeking a middle-ground, keeping it useful as it develops more modern designs. Other countries, such as Egypt, Saudi Arabia and Thailand are modernizing their M60 fleets for counter-insurgency type operations.
While the market for M60 modernization is somewhat limited, because the tank is generally operated by poorer countries or has been relegated to secondary tasks, other companies have come up with more advanced Service Life Extension Program (SLEP) upgrade solutions. Additionally, several countries also funded their own design upgrades, notable examples are the Magach, Sabra and Phoenix variants. In 2005, M60 variants were in service with Egypt, Greece, Israel, Jordan, Turkey, Taiwan and some 20 other nations to varying degrees.
High Performance/Super M60 Main Battle Tank
The High Performance M60, also called Super M60, was a comprehensive update package for the M60A1 and A3 tanks, first offered in 1985 by Teledyne Continental. The vehicle was developed as a private venture for the export market and was never evaluated for US military service. Unofficially called the M60AX, the upgrade offered to increase the protection, firepower and mobility for the M60A1 and A3 tanks.
Although the US Army chose not to adopt the installation of a new power pack or suspension system in the M60 series, General Dynamics formed a co-operative private venture with Teledyne Continental to develop a comprehensive upgrade package. The Super M60 prototype was based on an M60A1 leased from the US Army. It featured the AVCR-1790-1B engine producing 1,200 hp (890 kW) coupled to a Renk RK-304 transmission with four forward and four reverse gears. This High Performance configuration was demonstrated and tested at Fort Knox in January 1985 but was not designated.
The torsion bar suspension system of the M60 was replaced with a hydropneumatic suspension system (HSS) developed by the National Waterlift Company as seen on the HIMAG, General Motors XM1, and the Jordanian Centurion (Tariq). Over the M60A1, the Super M60's top speed increased to 45 mph (72 km/h) and power/weight ratio increased to 23.1 hp/t (17.2 kW/t), despite the 9,500 lb (4,300 kg) increase in weight. Survivability was enhanced with a layer of Chobham spaced applique armor built around the turret and frontal arc of the hull that noticeably changed its appearance.
The applique armor consisted of an outer layer of high-hardness steel armor panels and an inner layer of ceramic inserts covering the base M60A1 vehicle. Track skirts consisted of Sitall and high-hardness steel for the hull sides as well as Kevlar spall liners for the fighting compartment. Like the vehicle it is based on, it retained a crew of four: the commander, loader and gunner positioned in the turret and the driver in the front of the hull.
The weapons of the Super M60 are similar to those of the M60A3. The main gun is the rifled 105 mm/L52 M68A1E2 with a thermal sleeve. The 7.62 mm M73 coaxial machine gun used on the M60A1 was replaced with a 7.62 mm M240C, with the same number of rounds. The M19 cupola was replaced with a low silhouette model with a pop-up hatch for the commander and a 12.7 mm M2HB machine gun on a pintle mount with 600 rounds. The Fire Control System (FCS) used was designated the Advanced Laser Tank Fire Control System (LTFCS).
The FCS configuration was largely similar to that used on the M60A3, but instead of replacing the optical rangefinder with an AN/VVG-2 laser rangefinder, a Nd:YAG laser emitter was installed on the roof and the M35 gunner's sight was modified to include a laser visual unit. Also, the stabilization configuration was changed to that of the M1 Abrams where the sight itself was fully stabilized and the gun followed the sight. The prototype did not have an optical range finder but one could have been easily installed.
After initial tests with only the new engine and suspension, additional modifications such as the armor upgrade intended to increase protection from shaped charged projectiles were applied. Testing conducted not only showed that the new suspension system smoothened the off-road ride, but also allowed the Super M60 to handle well in spite of its considerable weight increase over the original M60A1. As one of the first upgrade packages offered for the M60 series, the Super M60 prototype demonstrated the potential for upgrading the M60A1/A3 and was offered by Teledyne Continental as one of their many possible upgrade packages.
Even though this update package offered M60 users an opportunity to dramatically increase the combat capabilities of their tank fleets, no country ever bought the update and the program effectively ceased by the end of the Cold War. Only one prototype was built. The overall failure of the Super M60 program was likely due to the lack of immediate necessity for such a vehicle. This design was similarly developed independently by Israel in their Magach 7 series. Additionally the German company Krauss-Maffei Wegmann offered the Super M48, applying this design's technology to the M48A2/A3.
M60-2000
The General Dynamics Land Systems (GDLS) M60-2000 or 120S was an upgrade of the M60A1 tank. The development of the M60-2000 was primarily due to the large number of M60 Main Battle Tanks in service with many Middle Eastern nations unable to afford a sufficient force of more modern main battle tanks. The upgrade was marketed at those M60 users with the industrial capability to convert the tanks themselves. The M60-2000/120S was a GDLS supplied conversion kit that married the M1A1 turret of the M1 Abrams to the M60A1 RISE hull, offering many features of the M1A1 Abrams to existing M60 users at a reduced cost.
It was first referred to the M60-2000 Program and design work began in late 1999 by General Dynamics Land Systems as a private venture for the export market and was never evaluated for US military service. Later the M60 designation was dropped because of the extensive changes and to highlight this as a new vehicle to potential customers thus changing the name to the 120S Project. The M60-2000 was test-marketed during 2000 and a number of countries in NATO and the Middle East were briefed on the vehicle. Following customer feedback, detailed engineering work was carried out and in December GDLS decided to build a functional prototype. The company rolled out the proof of concept prototype of the 120S tank at their Detroit, Michigan, facility in August 2001. It was shown at the IDEF Exhibition held in Turkey in October 2001.
The 120S was initially aimed at the Turkish Land Forces Command (TLFC) M60 upgrade requirement but this competition was subsequently won by IMI Military Industries with their Sabra II upgrade. The Egyptian Army was considering this offer until it was finally rejected in favor of a licensed contract to build M1s in Egypt. Only one prototype was made. As of early 2009 there were no sales of the 120S tank and was no longer mentioned in General Dynamics marketing literature. The prototype was disassembled and the hull and turret returned to the US Army in 2003.
M60A3 Phoenix
The M60 Phoenix Project was Jordan's modular upgrade of the M60A3TTS to better address both immediate and emerging threats to the M60MBT. The tank is armed with a RUAG Land Systems L50 120 mm smoothbore Compact Tank Gun (CTG) with a firing rate of 6-10 rounds per minute. 20 ready rounds are stored in the turret bustle. The M21 FCS is replaced with Raytheon's Integrated Fire Control System (IFCS). The system consists of an eye safe laser rangefinder, second generation night sight, digital ballistic computer, cant sensors and a MIL-STD 1553 data bus. The M10 ballistic drive is upgraded with a fully electrical superelevation resolver.
The maneuverability and acceleration of the Phoenix is improved with the use of the General Dynamics AVCR-1790-2C engine producing 950 hp increasing available power by 20%, an upgraded CD-850-B1 transmission, new air cleaner and air induction systems, improved suspension and new and improved final drives. Survivability is improved through the addition of various modular armor protection schemes for both the M60's turret and hull. The upgrades include armor protection with STANAG 4569 Level 6 protection plates to the frontal arc, passive and reactive armor panels and side skirts and slat armor added to the bustle, protecting the rear of the turret from RPG attack.
The protection scheme can be reconfigured to changing threat conditions. It also has a 12 tube High Speed Directed Launcher (HSDL) smoke screen system using a multi-spectral smoke hardxill providing protection against thermal detection. On 15 April 2004 Raytheon Company was awarded a $64.8 million contract by the Jordan armed forces to upgrade three tank battalions.
Raytheon has been working with Jordan's King Abdullah II Design and Development Bureau (KADDB) on its Phoenix Level 1 Independent Fire Control System (IFCS) upgrade and Level 2 Lethality upgrade efforts for the M60 main battle tank. Some of the upgrades included passive spaced armor packages, IR jammers and an ammunition containment system for the turret bustle. A $46.6M contract with the Jordan Armed Forces was authorized in 2012 to upgrade one battalion of their Phoenix main battle tanks.
Raytheon M60A3 SLEP
Raytheon in conjunction with other partners offered the M60 Service Life Extension Program (SLEP) for the M60A3 in May 2016. It has been marketed for export to nations that need the performance improvements to take on modern armor threats. The SLEP is offered as a collection of modular upgrades for the tank's firepower, mobility, and protection. This allows for SLEP customization to each user's needs. Its firepower improvements features the 120 mm M256/L44 smoothbore main gun as used on the M1A1 Abrams. It is fitted with a load assist system allowing for a firing rate of 6 to 10 rounds per minute and 20 ready-rounds in the turret bustle.
The Raytheon Integrated Fire Control System (IFCS) integrating an eye safe laser rangefinder, second generation gunner's night sight, digital ballistic computer, cant sensors, a fully electrical superelevation resolver and a MIL-STD 1553 data bus, giving the system capabilities similar to the M1AD standard. Other turret upgrades offered are the Curtis-Wright Gun Turret Drive and replacing the M19 cupola with a Hitrole remote controlled weapon system, that enables 360° panoramic surveillance from a secure position inside the tank armed with a M2HB .50cal machine gun.
Suspension and mobility upgrades include an upgraded AVCR-1790-2C engine producing 950 hp and improved hydropneumatic suspension. The installation of an Automatic Fire and Explosion Sensing and Suppressing system (AFSS) that improves soldier survivability and protects the engine compartment as standard. Upgraded armor protection with STANAG 4569 Level 6 protection plates to the frontal arc and side skirts and slat armor added to the bustle, protecting the rear of the turret from RPG attack. These changes increased the vehicle weight to 62-63 tons.
Leonardo M60A3 SLEP
The Leonardo M60A3 is a modular SLEP upgrade for the M60MBT offered in 2017 by the defense company Leonardo DRS. The upgrade is intended to offer nations already operating the M60 a modular upgrade solution for their vehicles to offer capabilities more in line with third-generation main battle tanks. It was unveiled 17 October 2017 at the Bahrain International Defense Exhibition and Conference (BIDEC). It has been marketed as an alternative upgrade to the Raytheon SLEP upgrade for M60MBT modernization.
Upgrades offered in this package include a new 120/45 gun from the Centauro II that offers a weight saving of 500 kg over the older 120/44 gun due to a redesigned light alloy cradle and muzzle brake. The old commander's cupola is completely removed and replaced instead with an armored circular ballistic plate protected with slat armor. This also offers a weight reduction compared to the original M19 cupola as used on the M60A3. For close defense, the turret is also fitted with the HITROLE-L 12.7 mm remotely operated weapons system.
The turret has been refitted with a new set of hydraulic and servo control improving performance. The rest of the vehicle is completely overhauled including the torsion bars, brakes, fuel supply, electric system, wheels, seals, paint, and smoke grenades. The vehicle has also been retrofitted with the Automatic Fire and Explosion Sensing and Suppression System (AFSS). It is equipped with the LOTHAR gun sight, DNVS-4 Driver's Night Vision Sight and TURMS digital fire control system. a daytime TV camera, and an eye-safe Laser range finder. IED jamming systems and a laser warning receiver systems developed by Leonardo are optionally offered.
Armor improvements include a whole new passive protection suite fitted around the M60's existing cast armor turret and hull that is claimed to meet STANAG Level 6 standards. Protection for the turret is optimized for protection against kinetic energy (KE) weapons and artillery across the frontal arc. The hull to is upgraded to the same standard with the protection covering the hull sides extending to the third roadwheel. For the rear of the turret, slat armor is provided with an emphasis on protecting against the RPGs.
Mobility is improved via either a full refurbishment of the existing power packs or an upgrade. The new powertrain offered is stated to deliver up to 20% more power without high costs and avoiding the need for any modifications to the existing hull. This AVDS-1790-5T 908 hp engine replaces the 750 hp engine and is connected to an upgraded CD-850-B1 transmission. It was unveiled at the Bahrain International Defense Exhibition and Conference (BIDEC) at Manama, Bahrain in 2017.
US service history
Fifteen of the early examples of the M60 produced had insufficient hull armor thickness, and were therefore used by the Armor School at Fort Knox to train tank crewmembers and maintenance personnel.
The M60 AVLB and M728 Combat Engineer Vehicle were the only variants of the M60 series deployed to South Vietnam during the Vietnam War. The M728 was used in fire support, base security, counter ambush fire, direct assault of fortified positions, and limited reconnaissance by fire. The AVLB provided gap crossing capabilities when required to support armored forces. M60 tanks were deployed at this time to West Germany during the Cold War to support US Army operations and participated in annual REFORGER exercises as well as Armed Forces Day parades in West Berlin until 1991. The M60 was also deployed to Korea to support US Forces Korea and participated in bi-annual Exercise Team Spirit maneuvers with South Korea notably with the US 2nd Infantry Division until 1991.
On 12 October 1973, President Nixon authorized Operation Nickel Grass that transferred M60 tanks to support Israel during the 1973 Yom Kippur War. On 21 August 1976, President Ford conferred with Henry Kissinger and green lighted Operation Paul Bunyan with a platoon of M60A1s reinforcing elements of the US 9th Infantry Regiment (Task Force Vierra) at the south end of the Bridge of No Return in response to the Korean axe murder incident.
M60 tanks participated in Operation Urgent Fury in 1983. Marines from G Company of the US 22nd Marine Assault Unit equipped with Amphibious Assault Vehicles and four M60A1 tanks landed at Grand Mal Bay on October 25 and relieved the Navy SEALs the following morning, allowing Governor Scoon, his wife, and nine aides to be safely evacuated. The Marine tank crews faced sporadic resistance, knocking out a BRDM-2 armored car. G Company subsequently overwhelmed the Grenadian defenders at Fort Frederick. The 1st Battalion, 8th Marine Regiment deployed with M60A1s to Beirut and were present during the subsequent October 23 Beirut barracks bombing near the Beirut International Airport during the ongoing Lebanese Civil War.
M60A1s have been historically used for ground force adversarial work during Exercise Red Flag as well as in close air support trials with the F-16 at Nellis Air Force Base, Nevada in the 1980s. During Operation Desert Storm in the Gulf War of 1991, at least one US Air Force unit was equipped with M60 tanks. The 401st TFW (P), deployed to Doha, Qatar had two M60A3 tanks for use by explosives ordnance disposal personnel. It was planned that using the tanks would allow the EOD crews to remove unexploded ordnance from tarmac runway and taxiway surfaces with increased safety.
M60A1s of the 1st Marine Division Task Force Ripper led the drive to the Kuwait International Airport on 27 February 1991. Task Force Ripper's M60A1 tanks destroyed about 100 Iraqi tanks and armored personnel carriers, including T-72 tanks. The division commander Maj. Gen. J.M. Myatt said, "During the first day of combat operations 1st Platoon, D Company, 3rd Tank Battalion destroyed 15 Iraqi tanks". The Marines also destroyed 25 APCs and took 300 prisoners of war. The next day, Marine M60A1 tanks encountered a minefield and attempted to proof two lanes with the MCRS. Both were unsuccessful. One MCRS missed a mine, which blew apart a track of the tank pushing it, immobilizing the tank and blocking the lane. The 1st Marine Division encountered more Iraqi opposition as it proceeded north coming into contact with the Iraqi 15th Mechanized Brigade, 3rd Armored Division. During this engagement the Marines destroyed an additional 46 enemy vehicles and took approximately 929 POWs. Once the 1st Marine Division reached Kuwait International Airport they found what remained of the Iraqi 12th Armored Brigade, 3rd Armored Division defending it. The Marines destroyed 30 to 40 Iraqi T-72 tanks which had taken up defensive positions around the airport.
After the conclusion of Operation Desert Storm, FORSCOM withdrew the M60 tank series from combat use and replaced it with the M1A1 Abrams for both the Army and Marine Corps. It was relegated to CONUS use with the Army National Guard through most of the 1990s. In May 1997, at Fort Riley, 1st Battalion, 635th Armor, Kansas Army National Guard, retired the last M60 series tanks in the US military. The 58 M60A3 tanks of the Kansas Guard's only armor battalion were unceremoniously parked in a holding pen at the Camp Funston Mobilization and Training Equipment Site (MATES), in the Kansas River Valley, down the hill from Fort Riley's main post. They were later transferred to the Jordanian Army.
Due to the restructuring of forces at the end of the Cold War, surplus US Army M1A1s were absorbed by the US Marines replacing their M60A1s on a one for one basis, allowing the Marine Corps to quickly become an all-M1 tank force at reduced cost. Except for a small number in TRADOC service for the combat training of units in Europe, most M60s were placed in reserve. Some 1,400 were transferred to NATO allies from 1991 to 1993 under the Treaty on Conventional Armed Forces in Europe and some were sold, mainly to Middle Eastern countries. Tanks were given to a few nations under governmental grants. They were finally declared as excess to US needs in 1994. They were superseded in National Guard service by the M1 version of the Abrams MBT and fully replaced by the M1A1.
After being retired from combat use in 1991, 18 M60A3s, with the M19 cupola removed, continued in active Army service to provide tactical combat training to US and NATO forces in Europe. They were fitted with the Multiple Integrated Laser Engagement System (MILES), given the mission to provide tactical engagement simulation for direct fire force-on-force training and were maintained at the Combat Maneuver Training Center (CMTC) near Hohenfels, Germany. They were used in the OPFOR Surrogate (OPFOR(S)) role by D Company 1st Battalion, 4th Infantry Regiment (Team Dragon) until May 2005. After their service as training aids, these examples were demilitarized and placed as target hulks on various firing ranges at the Grafenwoehr Training Area. They were replaced in this role by the Tonka tank (unofficial name) - an M113 OSV-T with a mock turret.
The large number of M60 series tanks still in the Army's CONUS inventory in 1994 were declared as excess to requirements and disposal of them began through grant programs or demilitarization at additional costs to the US government. As of 2015, the US Army and Air Force continue to use QM60s on a limited basis as targets for the testing of radar and weapons systems. They are also salvaged for parts to maintain other vehicles still in service. One M60A1 hull was leased to General Dynamics for development of the M60-2000/120S during 2000-2001.
The M68 105 mm Gun has been used for the M1128 Stryker MGS. Many are on public display in parks and museums or veteran service organizations as well as gate guards at military bases. Some 100 M60s are to be placed as artificial reefs off New Jersey and the Gulf coasts of Florida and Alabama accessible to scuba divers. The United States Army TACOM Life Cycle Management Command (TACOM-LCMC) has directed that the M728, M60AVLB and QM60-series target vehicles are to be withdrawn from use and logistical support by 2024 with any units remaining to be demilitarized and sold for scrapping through the DLA Disposition Services Defense Reutilization and Marketing Office (DLADS-DRMO).

Additional equipment
M9 Bulldozer Kit for the M60 series: (LIN B45390): The M9 bulldozer installed on the M60-series tank will increase the vehicle weight by 4.45 tons (4.04 metric tons). It is used to clear obstacles, leveling ground, filling depressions and to construct fighting positions. It is not to be used for demining activities. It is controlled by the driver.
M1 Mine Clearing Roller System (MCRS) (LIN M18157): The MCRS is installed on the front of the tank through a removable adapter, and provides the capability for neutralization of Anti-Tank (AT) land mines, which are buried or laid on the surface, in the track path of the vehicle. The MCRS consists of two roller banks with two push arm assemblies. Each roller bank has four rollers, which apply ground pressure higher than that exerted by the tank. This principle ensures the explosion of pressure fused anti tank mines, which would otherwise explode under the track itself. Additionally a Magnetic Actuating Device (MAD) is connected between the two roller banks. The system weighs 10 short tons (9.07 metric tons).
Vehicle Magnetic Signature Duplicator (VEMSID): (LIN V53112) The VEMSID increases the effectiveness and survivability of countermine equipment by causing the stand-off detonation of magnetic influence mines at a safe distance ahead of the tank. It generates a multi-axial magnetic signature optimized for passively fused magnetic influence fused mines. The system comprises four emitter coils, two associated power boxes and a MSD Control Unit (MSDCU).
Pearson D7 Surface Mine Plow (SMP) (LIN B71620): It is a track-width plow designed to skim the surface of a flat roadway or trail, not to defeat buried mines. It is controlled by the driver.
Track Width Mine Plow (TWMP) (LIN B71621): The Track Width Mine Plough (TWMP) uses a raking action to clear a safe path by bringing concealed or buried mines and improvised explosive devices (IEDs) to the surface and moving them wide and clear of the vehicle. It can be fitted with a MAD to counter magnetic influence fused mines.
Full Width Mine Rake (FWMR) (LIN B51986): A rake assembly for unearthing and disposing of buried and surface laid mines in sand and loose earth. It was specifically designed and fabricated for use in Operations Desert Shield and Desert Storm. The tank needs to have the M9 Buldozer Kit or a SMP installed first to employ the rake. It consists of a V-shaped tined plough that performs countermine activities by lifting buried mines with its tines and pushing them to the side as the vehicle moves forward. The FWMR also uses an aluminum skid shoe which protrudes from the front of the tines to allow the rake to maintain a consistent plowing depth. It clears a path measuring 180 inches wide, accommodating heavy tanks and other armored vehicles. Additional features are that it weighs 4000 pounds and is easily assembled and installed.
