M60A3 tank

Also known as
  • M60A3 TTS
  • M60A3 Passive
  • 105 mm Gun Tank M60A3
  • Tank, Combat, Full Tracked: 105-mm Gun, M60A3

The M60A3 is the final major U.S. production upgrade of the M60 main battle tank family, pairing the 105 mm M68E1 gun with laser rangefinding, a solid-state ballistic computer, crosswind sensing, and the later Tank Thermal Sight configuration. The cataloged conflict record covers Egyptian Sinai security deployments, Turkish cross-border use in Syria, and Republic of China crisis-response drills during the 2022 Taiwan Strait escalation.

Role in Conflicts

Side
Turkey

Turkish M60A3, M60T, and Leopard 2A4 tanks were hit by anti-tank guided missiles during Operation Euphrates Shield in Syria; Turkish defense reporting ties those M60A3 combat losses and survivability concerns to later M60A3 modernization work.

Role details
Side
Republic of China

Republic of China Army M60A3 tanks conducted counter-amphibious landing operations during Penghu live-fire exercises on August 24, 2022, amid the Fourth Taiwan Strait Crisis; the evidence supports crisis-response fielding and deterrent training, not combat use against opposing forces.

Fire-Control Upgrade

The M60A3 kept the M60A1 lineage's 105 mm gun and four-person layout, but its reader-visible difference is the fire-control suite rather than a new hull. The upgrade paired a laser rangefinder with the M21 ballistic computer and automatic inputs such as crosswind and cant sensing; TTS vehicles then added a thermal gunner's sight for night, smoke, haze, and other poor-visibility conditions.

Rangefinding

A laser rangefinder replaced the older optical rangefinder approach used on previous M60-family fire-control layouts.

Ballistic computer

M21 solid-state computer processed ammunition, range, crosswind, and other firing inputs.

Thermal-sight split

M60A3 TTS vehicles received the VSG-2 Tank Thermal Sight in place of the passive gunner's night sight.

Variants

Because this record covers the M60A3 and M60A3 TTS together, the variant list is limited to sourced adjacent designations rather than repeating the current model.

Danish A5 DK tanks saw direct conflict use in Bosnia in the 1990s, and refurbished A5-family vehicles later entered Ukrainian service as mobile direct-fire support tanks with better sighting and logistics than many older Soviet designs but far less protection than Leopard 2 variants.
