105mm Gun Tank M60 at the Russell Military Museum.

The turret and armament on this vehicle appears similar to that of the M48A5 tank, but the hull is noticeably different. The front hull is wedge-shaped and straight as opposed to M48's rounded bow, and the exhaust pipe for the personnel heater can be seen exiting to the hull's right side, in front of the fender stowage box. The lens for the rangefinder can be seen in the armored blister on the turret side, and the gunner's telescope was provided with a cover in the canvas dust shield. Although obscured from view, this early-production machine has one lifting eye forward on the turret roof and two to the rear. Later turrets had this arrangement reversed.

The commander's rangefinder was a coincidence model that did not require the visual acuity of older stereoscopic rangefinders. The commander used the vertical and horizontal adjustment knobs to align the target images from the left and right lenses until they were in coincidence. Once this occurred the range could be read through the range scale window. (Picture from TM 9-2350-215-10.)

A closeup of the ballistic computer M13A1D is provided in this picture. The range input shaft transmitted range information from the commander's rangefinder, and the superelevation output shaft likewise transmitted superelevation information from the computer to the ballistic drive. The superelevation handcrank allowed manual input of superelevation data into the computer. The range scale was graduated from 0 to 4,400m in 100-m increments. The range correction knob was used to compensate for variable conditions that could affect the gun's performance, such as ambient air temperature and density, gun tube wear, range error, and ammunition variation. It was graduated in intervals of 1% of the range for a total of ±15%. Tube wear was measured by the number of armor-piercing discarding sabot tracer (APDS-T) rounds fired: one round of APDS-T was the equivalent of 40 high-explosive plastic tracer or 1.5 high-explosive antitank tracer rounds. If the tube was new, a correction of -1% was entered. If 10 rounds of APDS-T equivalent had been fired, the correction was 0%, 20 rounds was +1%, 30 rounds was +2%, 40 rounds was +3%, 50 rounds was +4%, 80 rounds was +5%, 90 rounds was +6%, 110 rounds was +7%, 130 rounds was +8%, 150 rounds was +9%, 170 rounds was +10%, and 190 rounds and above was +11%. The inner matching dial indicated the same range as the rangefinder when the correction was 0%, and indicated different ranges depending on the correction factor. The outer matching dial could be manually operated by the superelevation handcrank or electrically operated by the computer, and rotated between the static range scale and the inner matching dial.

The forward portion of the loader's position is the subject of this picture, and the 105mm gun breech dominates the lower part of the image. The replenisher indicator tape was used to judge the amount of hydraulic oil in the replenisher; if one side of the tape had a rough edge while the other was smooth, the amount of oil was sufficient. If both edges of the tape were rough, the replenisher needed additional oil. If both edges were smooth or there were long notches on each side, the replenisher needed bled or drained.

Normal pressure in the seal was 0psi, but under the above two conditions it was to be inflated to 25psi (1.8kg/cm²). During a combat situation while fording the pressure could be decreased to 5-7psi (.4-.5kg/cm²) to permit the turret to traverse. (Picture from TM 9-2350-215-10.)

The tachometer/hourmeter and speedometer/odometer were to the driver's front. The hourmeter timed engine operation based on 2,025rpm per hour: that is, one hour rolled over if the engine ran at 2,025rpm for one hour. Thus, if the engine was run for one hour at 1,350rpm, the hourmeter would advance by ⅔ of an hour. The warning light by the tachometer indicated when the engine's oil pressure was low, and the warning light by the speedometer advised of high engine and transmission oil temperature and low transmission oil pressure.

Two independent fixed CO2 fire extinguisher systems provided protection against electrical, fuel, or oil fires in the engine compartment. Three cylinders were mounted to the driver's front left, and could be actuated by handles inside the driver's compartment or outside on the upper hull front. The driver's control handle (left) could be pulled to fire the first shot, then reset and pulled again after about 20 seconds for the second actuation. When the first shot was fired, a switch automatically cut fuel to the engine. If the handle malfunctioned, the safety keys could be removed from the cylinder control heads, and the emergency control head handles (center) could then be pulled all the way to the left to actuate the extinguishers. The external controls (right) featured separate handles for each shot. The emergency handles did not cut fuel to the engine. (Picture from TM 9-2350-215-10.)

105mm Gun Tank M60A1(RISE)(PASSIVE).

This vehicle is also fitted with the aluminum wheels, but note the horizontal hull tiedown eyes compared with vertical hull tiedown eyes the above vehicle. M60 and M60A1 hulls up to serial number 5025 had three vertical tiedown eyes rated at 20,000lb (9000kg) each. M60A1s from serial number 5026 and 152mm gun-launcher tanks M60A2 from serial number 4426 had four horizontal tiedown eyes rated at 490,000lb (220,000kg) side load and 413,000lb (187,000kg) oblique load. Late-production hulls were fitted with only two horizontal lifting eyes, as the middle two were deleted. This tank is equipped with the 1kw AN/VSS-3A xenon infrared searchlight, which is plugged into the receptacle on the turret roof. The light had a peak candlepower output of 50 million, and could operate with a compact beam of 1° minimum or a spread beam of from 1° to 7°. In front of this on the gun tube is a pyrotechnic device to simulate the firing of the main gun. The right-hand blister for the coincidence rangefinder is visible near the top of the turret just below the commander's cupola. Armored top-loading air cleaners are also visible on the rear fenders between the stowage boxes. This tank belonged to the 24th Infantry Division, and was taking part in Exercise GALLANT EAGLE '79 at Eglin Air Force Base. (Picture taken 25 Oct 1978 by SSGT Dwight A. Jackson; available from the Defense Visual Information Center.)

105mm Gun Tank M60A1(RISE)(PASSIVE).

This Marine tank is fitted with explosive reactive armor (ERA). These tiles are composed of explosive sandwiched between two steel plates. When struck by a high-explosive antitank (HEAT) shell or missile, the HEAT penetrator detonates the explosive, sending the plates in opposite directions. This action destabilizes the HEAT penetrator, making it less effective at penetrating the tank's armor. This tank was participating in the US/Thai exercise THALAY THAI '89. (Picture taken 1 Sep 1989; available from the Defense Visual Information Center.)

152mm Gun-launcher Tank M60A2 at the Patton Museum of Cavalry and Armor.

This early-production M60A2 retains the bore evacuator on the 152mm gun-launcher. Details of the suspension, such as the aluminum road wheels and friction snubbers on the first two and last road wheels, are also visible. A 23" (58cm) 2.2kw 100 million candlepower xenon searchlight is mounted on the turret's left side, in front of the loader's hatch. An infrared filter could be used as well, black on the AN/VSS-1 searchlight and pink on the AN/VSS-2. The light could be used in overdrive mode for 15-20 seconds once every five minutes, which increased its output to 150 million candlepower. The beam width for both the AN/VSS-1 and -2 was either 0.5-0.75° in narrow mode or 7° in wide mode. The beam was 1.2° high in each mode. With white light, the lamp had a planning range of 1500m; with the pink filter the AN/VSS-2 had an infrared planning range of 1000m.

The narrow cross-section of the turret can be glimpsed here. The upper part of the turret was not much wider than the gun mount, and the turret widens near the base for the gunner's and loader's stations. The service headlights and infrared headlights are obvious; above these in both headlight groups is a blackout driving light, and below them is a blackout marker light. The mounting locations for the driver's three M27 periscopes are visible in the upper hull, and the exhaust for the personnel heater can be seen running from the right side of the hull roof to the tank's right fender. This vehicle is running on the T142 track with replaceable rubber pads.

152mm Gun-launcher Tank M60A2.

The barrel of the gun-launcher on this tank lacks the bore evacuator seen on the previous vehicles. It is equipped with the closed-breech scavenging system, which rendered the bore evacuators redundant. The introduction of this system came about due to issues with burning fragments of the combustible ammunition cases remaining in the gun breech after the round had been fired. (Photo by Richard S. Eshleman.)

152mm Gun-launcher Tank M60A2.

This rear view shows the bulge under the rear louvres cause by the addition of the CBSS. The system was comprised of two 3100psi (220kg/cm²) air bottles, two gear-driven compressors, and other associated equipment, and it would deliver three 1000psi (70kg/cm²) shots of air after each main gun round was fired. The system was triggered by the recoil of the gun-launcher. Across the back of the turret, from left to right, is a stowage basket, turret ventilator blower, and the stowage point for the searchlight. The large size of the commander's cupola can also be ascertained. (Photo by Richard S. Eshleman.)

The bore evacuator on the 152mm gun-launcher is apparent, positioned about halfway down the short gun tube. The housing above the gun was for the Shillelagh missile's infrared transmitter. The gunner's M126 telescope is visible, and under the padlocked cover above the telescope is the aperture for the tank's laser rangefinder. The telescope was the sight used for the missile, and the primary sight for canister and coaxial machine gun engagements. It was the secondary for HEAT-MP shells after the gunner's M50 periscope. The external triggers for the tank's fire extinguishers are visible under the guard on the hull front slope.

The series of lights across the top indicated, from left to right, an OK computer self test; a defective computer unit; a defective output unit; a defective reticle projector unit; a defective gunner's control unit; a defective cant unit; a defective laser rangefinder unit; and a defective or missing crosswind sensor, or that the system was being operated in manual wind mode. The air temp and altitude knobs were used to input those values into the computer. Panel lights are between and outside of these knobs, and five more are present on the lower portion of the unit. In the lower right corner of the upper section is the manual/rangefinder switch, which determined if the computer accepted input data from the rangefinder or the range dial on the right side of the gunner's control unit.

At the upper left of the lower section is the remaining tube life percentage control knob, and below this is the switch to put the system into boresight mode, where all computer functions except parallax and range were deactivated. The knob between the left and center panel lights at the top told the computer to calculate for either M728 or M392 APDS ammunition, while the knob to the right set the computer to calculate for M456 HEAT ammunition. The spare position on this knob was not used. At the right of the top row is the crosswind mph control to manually input crosswind speed from the right or left. The Common Zero column of knobs at the left offset all azimuth (top) or elevation (bottom) settings of individual controls by a fixed amount. To the right of these are the APDS azimuth (top) and elevation (bottom) zeroing controls. To the right of these are the HEP/WP azimuth and elevation zeroing controls, and to the right of these are the HEAT azimuth and elevation zeroing controls. The final column of knobs on the right are the FSDS azimuth and elevation zeroing controls. On the inside of the hinged cover at the bottom are areas to log the various settings used.

105mm Gun Tank M60A3(TTS) in Chillicothe, Ohio.

This tank is externally similar to the M60A1 above. Friction snubbers on the first two and last road wheels are obvious. The front road wheel arm was equipped with double bump stops, compared to single bump stops on the other wheels. The single bump stops can be seen behind the road wheels. The exhaust pipe for the personnel heater can be seen in front of the forward fender stowage box, and a triangular mount for a smoke grenade launcher assembly is visible on the forward turret below the grab handle.

105mm Gun Tank M60A3(TTS) in Chillicothe, Ohio.

The right side of the turret was home to the commander's cupola and the gunner's periscope sight. The round aperture for the commander's M85 machine gun is visible in the cupola's front, and a periscope guard is present on top of the cupola. From the turret mounting surface, the cupola is 21.56" (54.76cm) tall to the periscope guard and 16.57" (42.09cm) without the periscope guard. Its inner diameter was 34" (86cm) and its total diameter was 52.25" (132.7cm). With the M85 machine gun and 180 rounds of ammunition, the cupola weighed 2439lb (1106kg). Mounted just beside the gunner's periscope is an interrupter bar that, when swung to the vertical position, was meant to prevent the commander's machine gun from firing down onto the gun shield-mounted searchlight. The rounded top to the gunner's periscope guard indicates that this tank is equipped with the AN/VSG-2 tank thermal sight. Non-TTS tanks (like the M60 above) had a flat-topped periscope guard.

The loader had his own hatch in the left side of the turret roof, and an M37 periscope was provided in his hatch door. The flexible base of the crosswind sensor is visible on the rear of the turret, and hidden from view behind the commander's cupola is a turret ventilator. The left-side rangefinder blister is empty since the laser rangefinder only occupied the opposite blister. Note that the xenon searchlight receptacle has been capped on this tank, since it was no longer necessary.

105mm Gun Tank M60A3(TTS).

The right side of the turret is detailed in this picture. The commander's seat is elevated to the right, and the gunner's position is directly to the front and below. The commander's black control handle sits atop the turret traverse gearbox assembly; the commander's control handle was connected to the gunner's control assembly by the two rods: the upper elevation rod and lower traverse rod. The unmarked white box directly behind the gearbox assembly on the turret wall is the electronics controller unit. Directly behind his control handle on the turret wall with is his ammunition select box. The black box on the turret wall above and to the right of the ammunition select box is the commander's communication control box, and the networks box for the cupola power switch and circuit breakers for the stabilization electronics and power pack blower motor is to the right of this. The laser rangefinder can be seen near the top of the image; the upper black knob was for adjusting deflection while the lower knob was for adjusting elevation. In front of the turret traverse gearbox is the gunner's azimuth indicator, with his large control unit and smaller stabilization control box and gun control boxes going forward along the turret wall. Above the stabilization control box is the turret hand traverse drive; the shaft from this handle connects to the turret gearbox assembly via the no-bak assembly, which prevents the rotation of the hand traversing drive handle when the turret is using hydraulic power, or when the turret rotates due to being on a slope or when the gun tube strikes an obstacle. The gunner's control handles can be seen on the lower left. The tank thermal sight is not mounted, but the commander's extension would snake along the turret wall above where the rods exiting the front of his override handle have been bent downward. The gunner's telescope remains, however. (Photo by Richard S. Eshleman.)

The protective flap on this blister would open when the laser rangefinder was in use. The rangefinder could detect targets from 200m to 4700m and had a maximum lasing rate of 3 per minute, or 6 per minute for 2 minutes followed by a 3-minute cooling period. An armored fender-mounted air cleaner is visible behind the rangefinder blister between the fender stowage boxes.
