Historical overview
The M60 was a Cold War main battle tank born from the M48 Patton lineage but standardized as a new vehicle with the 105 mm M68 gun, diesel AVDS-1790 powerpack, improved range, and revised armor/hull features. The First Division Museum emphasizes its 1960 service entry and its role as a counter to Soviet tanks that had surpassed the 90 mm M48 in firepower. AFV Database gives December 1960 as the first acceptance date for the original M60 and 2,205 acceptances for that model. [First Division Museum; AFVDB M60] Sources
It mattered because it was a pragmatic bridge between the gasoline-engined Patton era and the M1 Abrams. The Army wanted a better answer to T-54/T-55 and later T-62 threats while more ambitious replacements, including T95, MBT-70, and other advanced tank projects, failed or slipped. The result was a 'stopgap' that became a long-serving standard: M60A1 entered acceptance in 1962, the unusual M60A2 experimented with the 152 mm Shillelagh gun/launcher, and the M60A3/TTS gave the late M60 family laser ranging, a new fire-control system, and thermal night-fighting capability.

The most important variants are the original M60, M60A1, M60A1 AOS, M60A1 RISE, M60A1 RISE Passive, M60A2 Starship, M60A3, and M60A3 TTS. The family also produced important specialized vehicles, especially M60/M60A1 AVLB bridge-layers and the M728 Combat Engineer Vehicle. The cited accounts further links M60T/Sabra, Jordanian Phoenix, Turkish FIRAT/TİYK upgrades, M60-2000/120S, and other post-Cold-War upgrades as boundary carry-forward records. Sources
Major disputes center on counting. AFV Database provides model acceptances for original M60, M60A1, M60A2, and M60A3, while museum and general reference sources use broader family totals. The Tank Museum states production ended after 13,634 tanks, whereas the cited accounts and several common references use about 15,000 when major variants, export programs, and conversions are counted. The safest treatment is to cite precise model acceptance numbers where available and treat all aggregate totals as count-definition dependent. [AFVDB M60; Tank Museum Pattons] Sources
The M60 was not revolutionary, but it was strategically successful. It gave U.S. and allied armored forces a powerful 105 mm diesel MBT in large numbers, absorbed several decades of fire-control and reliability upgrades, fought in Middle Eastern wars and the Gulf War, and remains the basis of active or recently active foreign modernization programs. Its weak points were high silhouette, aging armor architecture, limited growth compared with later composite-armored MBTs, and a failed missile/gun detour in the M60A2. Its strongest historical claim is that a conservative tank, kept modern through upgrades, can matter as much as a technically more ambitious replacement that never arrives. Sources
The M60 emerged from a decade of U.S. Army frustration with postwar tank replacement cycles. The M46, M47, and M48 had all been shaped by rushed requirements, delays, or stopgap logic. By the mid-1950s, the M48 family gave the Army a useful medium tank, but its early gasoline-engine range and 90 mm gun left room for improvement. Meanwhile, Soviet T-54/T-55 and later T-62 tanks gave NATO planners a growing firepower and numbers problem along the inner-German border. [Tank Museum Pattons; USAHEC] Sources
The military problem was straightforward: obtain a tank with better gun performance, longer range, acceptable armor, and diesel safety/fuel economy before an all-new advanced tank could be matured. The U.S. studied the new T95 family, but that program was technologically ambitious and slow. A faster path was to update the M48 lineage with the AVDS-1790 diesel, redesigned hull features, and a U.S. version of the British 105 mm L7 gun, the M68. [Tank Museum Pattons; AFVDB M60] Sources
Doctrine was still built around armored units that could move, shoot, communicate, and survive under nuclear-age and conventional conditions. Later FM 17-15 language for tank platoons stresses the enduring mission to close with and destroy enemy forces using fire, maneuver, communications, and armored protection. The M60 served in that doctrinal world: not as a boutique weapon, but as the standard tank platoon's workhorse until Abrams replaced it in the most capable formations. [FM 17-15] Sources
Industrial constraints favored continuity. A dieselized M48-derived vehicle could be standardized and produced through existing U.S. heavy-vehicle industrial channels while more radical projects failed. This explains why the M60's historical significance is not only technical. It is also a procurement story: the useful tank that the Army could actually field beat a succession of more advanced but less deliverable replacements. Sources
Development and variants
Included are U.S. production gun tanks, major upgrades, experimental or specialized derivatives, export service, and post-Cold-War upgrade lineages where they are derived from M60A1/M60A3 hulls. The account does not merge every M48/Magach/ vehicle into M60; those are discussed as related lineages or boundary cases. Sources
The M60 is normally classified as a main battle tank. The M60A2 complicates that classification because its 152 mm M162 gun/launcher and Shillelagh missile system pushed it toward a missile-tank concept, but it remained a tank in U.S. service rather than a separate tank-destroyer branch. The M728 CEV and AVLB are tank-derived specialized engineering vehicles; they belong in the M60 family tree but does not represent gun-tank production unless the source explicitly does so. [AFVDB M60] Sources
It does flag post-Cold-War upgrade records as boundary carry-forward, especially F-US-M60UP, M60T/Sabra, Turkish FIRAT/TİYK-related records, Jordanian Phoenix, and Iranian Samsam. Those records are included here for lifecycle completeness but cannot be retroactively treated as 1960s U.S. production variants. Sources
The M60 design path drew from the M48A2 and T95-era improvement studies. The Tank Museum summarizes the Army's choices as either a new T95 tank or an upgraded M48 using a diesel AVDS-1790, siliceous-cored armor plans, and the M68 105 mm gun. T95 was cancelled in July 1960, but the upgraded design had already been adopted as M60 in March 1959. Officially, the M60 was not christened Patton, even though it belongs to the broader Patton family in design lineage and popular language. [Tank Museum Pattons] Sources
Development is best treated as a 1957-1959 design and standardization process followed by 1959-1960 production acceptance. The cited accounts uses 1957-1959 as development/start. The file name follows the cited accounts line and the cited accounts start year, 1957. AFV Database gives December 1960 as the original M60's date of first acceptance; the First Division Museum and USAHEC describe 1960 service introduction. [AFVDB M60; First Division Museum; USAHEC] Sources
M60A1 followed quickly. AFV Database gives October 1962 as first acceptance and 7,948 acceptances. Its key visible change was a longer, needle-nosed turret derived from T95E7 work, with better internal space and thicker protection. Over the 1970s it received top-loading air cleaners, the AOS stabilization package, RISE reliability improvements, smoke grenade launchers, and RISE Passive night-vision improvements. [AFVDB M60; Tank Museum Pattons] Sources
The M60A2 was the most ambitious and least successful branch. It mounted a low-profile turret and the 152 mm M162 gun/launcher for conventional rounds and the MGM-51C Shillelagh missile. AFV Database records 1973 as first acceptance and 540 acceptances, while the cited accounts uses about 526 and marks the number for verification. The technical idea was attractive in the missile-enthusiasm era, but the vehicle was maintenance-heavy, tactically awkward, and short-lived. [AFVDB M60] Sources
M60A3 was the final major U.S. standard. It kept the 105 mm gun but modernized target acquisition and fire control. DA Historical Summary FY1985 describes M60A1-to-M60A3 conversion as adding gun stabilization, laser rangefinder, solid-state computer, thermal shroud, and thermal imaging sight. DAHSUM FY1984 reports that Army production of M60A3 TTS concluded in FY1984 with 1,052 built since FY1980, while retrofit and conversion programs had already produced 3,191 M60A3 TTS tanks by that point and planned thousands more conversions. [DAHSUM FY84; DAHSUM FY85] Sources
Design and performance
The core M60 layout was conventional for a U.S. Cold War MBT: driver in the hull center front; commander and gunner on the turret right; loader on the turret left. AFV Database gives four-man crew positions for M60, M60A1, M60A2, and M60A3 in this general arrangement. The layout preserved a human loader and large turret bustle/volume rather than adopting an autoloader. [AFVDB M60] Sources
The original M60's hull is one of the easiest ways to distinguish it from M48. The M60 used a wedge/flat front rather than the M48's boat-shaped nose; this reflected the planned use of flat siliceous-cored armor panels. That armor scheme was not adopted because of cost and industrial constraints, but the hull form remained. The vehicle used cast homogeneous steel hull sections and retained torsion-bar suspension with rear drive sprockets and front idlers. [AFVDB M60; Tank Museum Pattons] Sources
The original M60 turret resembled the M48 lineage. M60A1 introduced the long-nose turret with cutaways under the front and improved internal volume. M60A2 used a distinctive low-profile missile/gun turret with a short-barreled 152 mm gun/launcher. M60A3 returned to the M60A1-style 105 mm turret architecture but added fire-control, smoke, and sighting improvements. [AFVDB M60; Tank Museum Pattons] Sources
The M60 family used cast and welded homogeneous armor rather than Chobham-style composite armor. AFV Database gives detailed values for the original M60 and M60A1, including an original M60 turret front rated at 7.0 in equivalent and an M60A1 turret front of 10.0 in equivalent; the First Division Museum gives a simplified.93-7.0 in armor range for its M60 exhibit. Sources
The core gun was the 105 mm M68, an American derivative of the British L7. AFV Database describes the M68 as equivalent to Britain's L7 but with a vertical sliding breechblock and eccentric bore evacuator, among other U.S. differences. Original M60 carried 57 rounds; M60A1 and M60A3 carried 63 rounds in AFVDB data. [AFVDB M60] Sources
M60A2 replaced the M68 with the 152 mm M162 gun/launcher. AFV Database records 33 conventional rounds plus 13 MGM-51C Shillelagh missiles for M60A2. It notes a maximum missile range of 3,000 m and a minimum range of 800 m because guidance took time to become effective; the conventional HEAT-MP round was therefore the closer-range default. [AFVDB M60] Sources
Original M60 armament included an M85.50-caliber cupola machine gun and an M73 7.62 mm coaxial machine gun; early production problems caused the first 300 vehicles to use a pedestal-mounted M2HB and the first 45 to lack the cupola. M60A1 used M85 in the cupola and M73/M219 coaxial guns. Sources
The 105 mm family fired APDS/APFSDS, HEAT, HEP/HESH-type, white phosphorus, anti-personnel, and practice ammunition depending on period and operator. The First Division Museum lists armor-piercing, HEAT, APERS, high-explosive plastic, and white phosphorus ammunition for its M60 exhibit. By the 1980s, 105 mm ammunition improvement remained active because both M60 and early M1 fleets still used 105 mm guns. DAHSUM FY1984 mentions a 105 mm Tank Gun Enhancement Program including the XM900 round and XM24 extended 105 mm tube. [First Division Museum; DAHSUM FY84] Sources
The original M60 used an optical coincidence rangefinder and integrated fire-control equipment. M60A1 AOS added gun stabilization. M60A3 added laser rangefinder, solid-state ballistic computer, thermal shroud, and improved fire-control architecture; TTS added a thermal imaging sight. DAHSUM FY1985 explicitly identifies stabilization, laser rangefinder, solid-state computer, thermal shroud, and thermal imaging sight as M60A1-to-M60A3 conversion features. [First Division Museum; AFVDB M60; DAHSUM FY85] Sources
M60 and M60A1 used day optical sights, coincidence rangefinders, and infrared/passive night devices depending on variant. M60A1 RISE Passive replaced active infrared dependence with passive night sights for gunner and commander. M60A3 TTS introduced the Tank Thermal Sight, making the final U.S. M60 much more credible in night and obscurant conditions than earlier M60A1 configurations. [AFVDB M60; Tank Museum Pattons] Sources
The central automotive feature was the Continental AVDS-1790 air-cooled V-12 diesel. AFV Database gives 750 gross horsepower for M60 and M60A1/A2, with GM CD-850 cross-drive transmissions. The First Division Museum also gives 750 hp, 385 gal fuel capacity, 30 mph speed, and 300-mile range for its M60 exhibit. [AFVDB M60; First Division Museum] Sources
The M60 family used torsion bars, six dual road wheels per side, three return rollers, rear drive sprockets, front idlers, and 28-inch double-pin tracks. AFV Database gives a sustained 30 mph road speed and about 300 mi cruising range for M60/M60A1; M60A2's range is listed at about 280 mi. Later RISE packages improved reliability through air cleaners, engine components, fuel systems, starter equipment, and track changes rather than changing the basic mobility class. [AFVDB M60] Sources
The four-man crew preserved loader workload and U.S. gunnery practice. M60A1 improved internal seating and pedal arrangements. M60A2's unusual turret made crew ergonomics and maintenance less forgiving; commander, gunner, and loader had more specialized positions around the M162 gun/launcher and missile electronics. [AFVDB M60] Sources
Radio fits varied by period, branch, and operator. For the U.S. Army and Marine Corps, the M60 served within standard armored platoon command-and-control structures rather than as a special command vehicle. FM 17-15's tank-platoon doctrine underlines communication as one of the tank platoon's essential capabilities, alongside movement, shooting, and armored protection. [FM 17-15] Sources
Protection systems grew over time. Smoke grenade launchers appeared on late M60A1 upgrades and M60A3. M60A1 RISE Passive vehicles in U.S. Marine service were often fitted with explosive reactive armor for Operation Desert Storm. Modernized export vehicles such as M60T/FIRAT add new armor packages, sensors, situational-awareness equipment, and, in some cases, local fire-control systems. [AFVDB M60; MCUP Always Faithful; SSB 2024; ESD 2024] Sources
The M60's diesel powerpack and conventional architecture made it more maintainable than many more ambitious Cold War tank projects. RISE packages focused explicitly on reliability. Known weaknesses were the high silhouette, aging steel-armor protection against later APFSDS and ATGMs, limited growth compared with composite-armored successors, M85 machine-gun and early cupola issues, and M60A2's complex and maintenance-heavy missile/gun system. [AFVDB M60; Tank Museum Pattons] Sources
Production, operators, and combat record
AFV Database identifies Detroit Tank Arsenal and Chrysler Corp. for the original M60, Detroit Tank Arsenal for M60A1, and Chrysler Corp. for M60A2 and M60A3. The M60 family thus sits squarely in the U.S. Cold War armored-industrial base that had grown out of Second World War tank production and postwar Chrysler/Detroit Arsenal capacity. [AFVDB M60] Sources
Published accounts describe M60 production as 1959-1983, with conversions to 1990. AFV Database gives first acceptance dates of December 1960 for M60, October 1962 for M60A1, 1973 for M60A2, and May 1979 for M60A3. DAHSUM FY1983 and FY1984 show M60A3 production and conversion continuing through the early 1980s, including FMS production and depot conversion work at Anniston and Mainz. [AFVDB M60; DAHSUM FY83; DAHSUM FY84] Sources
Quoted family production totals depend on which vehicles and conversions are included. AFV Database provides acceptances of 2,205 M60, 7,948 M60A1, 540 M60A2, and model-specific M60A3 data; DAHSUM provides program figures for M60A3 TTS production, retrofit, and conversion. The Tank Museum gives 13,634 tanks for total M60 production ending in 1987. The cited accounts uses about 15,000 including major variants. These are not necessarily contradictions unless all sources are claiming the same counting basis; the difference may reflect whether the total includes rebuilt vehicles, export/FMS tanks, specialized hulls, or late conversions. [AFVDB M60; Tank Museum Pattons] Sources
A consistent per-tank cost series is not established in the cited accounts. Industrial difficulties included early cupola and M85 machine-gun production, the cost of the proposed but unadopted siliceous-cored armor, the M60A2 gun/missile installation, and large-scale depot conversions. The Army’s FY1984 historical summary identifies Anniston and Mainz depots as central to M60A1-to-M60A3 TTS work. [AFVDB M60; DAHSUM FY84] Sources
The M60 family's production success was not that it froze a design in 1960. It was that the industrial base could keep rebuilding, improving, exporting, and supporting it for decades. That made it a durable asset even after newer MBTs appeared. Sources
The M60 was originally a U.S. Army tank and was also used by the U.S. Marine Corps. It became a major export and aid vehicle across NATO-aligned and U.S.-aligned forces. Sources
USAHEC states that the U.S. Army retired the M60 series in 1997 in favor of M1A1 Abrams; The Tank Museum similarly states that the last Pattons in U.S. service were retired in May 1997 after the Gulf War swansong. DAHSUM FY1985 shows the planned early-1990s tank mix moving toward M60A3, M1, and M1A1 while older M48A5, M60, and M60A1 were to be eliminated. [USAHEC; Tank Museum Pattons; DAHSUM FY85] Sources
Outside the United States, the M60 survived because many users could not replace large armored fleets at once. The most visible current/recent example is Turkiye: in February 2024, the Turkish defence-industry authority announced delivery of the first modernized M60T tanks under a project that replaced foreign-origin FCS with the national VOLKAN-M system and integrated modernized subsystems. Taiwan is another key case, with M60A3 and / lineages remaining relevant during the M1A2T transition. [SSB 2024; ESD 2024; OCAC 2026] Sources
The M60 family saw extensive combat in Middle Eastern service, especially in Israeli and Iranian hands. Iran used M60A1 vehicles delivered before the 1979 revolution during and after the Iran-Iraq War; current status and exact modernization claims are uncertain in the available accounts. Sources
The best-documented U.S. combat endpoint is Operation Desert Storm. Marine Corps University Press describes the M60's 'last hurrah' in Chapter 4 of Always Faithful and identifies the M60A1 'Genesis II' as a featured artifact. It places the Desert Storm ground campaign starting on 24 February 1991 and lasting roughly 100 hours. The narrative describes Task Force Ripper and 3d Tank Battalion entering the Burqan oil field and destroying Iraqi tanks; it also notes that Marine M60s in Desert Storm were upgraded with passive night sights and explosive reactive armor. [MCUP Always Faithful] Sources
The U.S. Marine M60A1 was not equal to an Abrams in survivability, speed, or modern growth potential, but in 1991 it remained a capable 105 mm platform in Marine hands. The same MCUP chapter states that after Kuwait the Marine Corps purged the M60 and transitioned to Abrams. That makes Desert Storm a clean narrative endpoint for U.S. combat use even if foreign M60-derived vehicles continued to fight later. [MCUP Always Faithful] Sources
Turkish M60T/Sabra and later FIRAT-related vehicles have been linked to combat service in Syria. Specific loss claims, active protection status, and exact fleet counts vary by source and are not asserted here without a dedicated operator-level study. [SSB 2024; ESD 2024] Sources
Legacy and historical evidence
Firepower: strong for a 1960s tank; M68 105 mm gave NATO-standard lethality and a long ammunition growth path. Sources
Armor: respectable steel armor in M60A1 form, but no composite armor and increasingly vulnerable by late Cold War standards. Sources
Mobility: good range and reliability compared with early gasoline Pattons, but not exceptional against Leopard 1 or Abrams. Sources
Reliability: generally solid in conventional gun-tank variants; M60A2 is the major exception. Sources
Ease of production: strong because it used an existing U.S. industrial/support base and could be rebuilt repeatedly. Sources
Crew effectiveness: four-man layout and improved FCS helped; M60A3 TTS notably improved night fighting. Sources
Strategic impact: high because of scale, export reach, and long service life rather than single-vehicle technical novelty. Sources
The M60's influence lies in two overlapping legacies. First, it preserved and perfected the Patton-lineage idea of a conventional, four-man, Western gun tank through the 1960s and 1970s. Second, it became one of the clearest examples of a tank whose useful life was extended through fire-control, reliability, armor, and export upgrades long after the original design baseline was obsolete. [Tank Museum Pattons] Sources
Doctrinally, the M60 bridged the Army from optical-rangefinder and active-IR Cold War tanking to laser rangefinders, solid-state ballistic computers, thermal sights, and Abrams-era platoon tactics. It also showed the limits of missile enthusiasm: M60A2's failure did not kill guided weapons, but it did discredit a complicated gun/launcher tank that could not justify its maintenance burden. [DAHSUM FY84; DAHSUM FY85; AFVDB M60] Sources
The export legacy remains visible. M60T/Sabra, Turkish FIRAT/TİYK upgrades, Jordanian Phoenix, Taiwan's M60A3// ecosystem, Egyptian upgrade packages, and Iranian Samsam claims all show that large Cold War MBT fleets can remain militarily and politically relevant through modernization. These are boundary carry-forward vehicles: they are descendants of the M60, not evidence that the 1960 M60 itself remains a front-line peer of modern MBTs. [SSB 2024; OCAC 2026] Sources
Surviving vehicles are common in museums, outdoor memorials, base displays, and collections. The abundance of survivors is itself a research advantage: it enables visual comparison of turret forms, rangefinder blisters, smoke launchers, ERA kits, dozer/plow fittings, and post-service display modifications.
