About this creation


























Historical Information:

During the Hungarian Revolution of 1956, a Soviet T-54A medium tank was driven onto the grounds of the British embassy in Budapest by the Hungarians. After a brief examination of this tank's armor and 100 mm gun, British officials decided that their 20 pounder was apparently incapable of defeating it. There were also rumors of an even larger 115 mm gun in the works. Hence there was a need to adopt a 105 mm gun, which emerged as the famed Royal Ordnance L7. This information made its way to the United States, where the Army had been experimenting with a series of upgrades to their M48 Patton tanks. Most were relatively minor, all retaining its 90 mm gun. These experiments were concerned with improving the armor and the introduction of a variety of autoloader systems and upgraded rangefinders.

The T95 program, launched after the Questionmark III conference in June 1954, was the intended replacement to the M48. It featured a host of innovative and experimental components such as its 90 mm smoothbore T208 cannon rigidly affixed to its turret, and its new powertrain and suspension. The burden of developing them however slowed the overall program to a crawl. General Taylor approved of a new tank development program in August 1957. This incorporated many ARCOVE recommendations and foresaw the eventual replacement of the light, medium, and heavy tanks with two types the airborne reconnaissance/assault vehicle and the Main Battle Tank. The MBT was to combine the firepower and protection sufficient for the assault role with the mobility to perform as a medium tank. A tank of the T95 series, armed with a smoothbore cannon and powered by a compression ignition engine, was envisaged by the Army Staff as the bearer of the role of future MBT.

The course of this tank program was the source of widespread debate. The Bureau of Budget (BOB) believed that the Army was not progressing with sufficient speed in its tank modernization program and recommended the immediate replacement of the M48A2. Correctly predicting that the BOB would not approve the procurement of the M48A2 after the fiscal year of 1959, the Deputy Chief of Staff, Logistics (DCSLOG) proposed a tank based on the M48A2 featuring improved firepower and the AVDS-1790 engine. Of course the alternative was to introduce a tank from the T95 series but it remained highly experimental with its compression ignition engine not as developed as the AVDS-1790. An influential group of senior officers, by May of 1958, concluded that the T95 had only marginal advantages over the M48A2. They proposed that the most important improvements, better firepower and fuel economy, could be achieved by mounting a compression ignition engine and a more powerful gun on the M48A2.

In 1957, plans were laid in the US for a universal or all purpose tank. Fulfilling this requirement with an interim tank resulted to the M60 series, which largely resembles the M48 it was based on, but has significant differences. The M60 mounted a 105 mm M68 main gun with the bore evacuator mounted towards the middle of the tube, compared with the M48's 90 mm M41, which mounted the bore evacuator towards the end of the tube right after its T-shaped blast deflector. It also had a hull with a straight front slope whereas the M48's hull was rounded, had three support rollers per side to the M48's five, and had road wheels constructed from aluminum rather than steel, although the M48 wheels were often used as spare parts.

The improved design incorporated a Continental V-12 750 hp (560 kW) air-cooled, AVDS-1790-2 diesel engine, extending operational range to over 300 miles (480 km) while reducing both refueling and servicing. Power was transmitted through a CD-850-6 cross drive transmission, a combined transmission, differential, steering, and braking unit.

The hull of the M60, like its predecessor the M48, could be cast as cast as a single piece or by welding smaller castings. The turret was similar to the M48A2's and was made as a single piece casting although it was modified to accept the new larger diameter cupola and the M116 mount for the 105mm gun. The hull was divided into three compartments, with the driver in front, fighting compartment in the middle and engine at the rear. The driver looked through three M27 day periscopes, one of which could be replaced by an M24 infrared night vision periscope.

The M60 was the last U.S. main battle tank to utilize homogeneous steel armor for protection. It was also the last to feature an escape hatch under the hull. (The escape hatch was provided for the driver, whose top-side hatch could easily be blocked by the main gun. Access between the driver's compartment and the turret fighting compartment was also restricted, requiring that the turret be traversed to the rear).

Originally designated the XM60, the new vehicle was put into production in 1959, standardized as the 105 mm Gun Full Tracked Combat Tank M60 on 16 March 1959, and entered service in 1960. There was a proposal in April 1959 to change the nomenclature to 105 mm gun main battle tank M60; this was however rejected due to a conflict with the Federal Cataloging Agency Policy. Over 15,000 M60s (all variants) were built.

Model Information:

- Rolling Tracks
- Elevating and Depressing main gun
- Rotating turret (In theory)
- Moving Trailing Arm Suspension, but nothing to actually 'Spring' it...

Builders Notes:

I wanted to see how my new PC could handle LDD, and as expected it's like a walk in the park for it. The renders all told took around 10 minutes to render including not seen images which I re-rendered...

This whole build would have taken my old PC a day to complete, render, and post, but I've gotten everything done in less than 4 hours, I'm hitting levels of productivity that shouldn't even be possible...

As for the build, the turret from my 59-Patton fit with minor modifications, and while overall the tank isn't as detailed as I'd liked, as this scale it is what it is... That said building the lower hull was quite fun because it's like a boat, not really flat armor plates.

Quoting BATOH rossi nice, well shaped ... maybe the barrel of the cannon should be longer ... anyway nice job;)
It's one of those 'Just a little longer would be perfect, but the pieces available make it too long and thus unacceptable' situations... Thanks for the comment!
