The biggest question is which version of the M48 vs which version of the M60??

That could qualify as many as 8 tanks.

Here is a frontal of an M48A1. I'm searching for several other versions of M48 that I know I have floating around.

As for M60, Joe D seems to have a good 'corner' on that one...

Interestingly, the M60 bow ha a flat face because it was originally planned to include a kind of fiberglass sandwich armor. But the cost was too high so they opted for standard solid steel... BUT the Soviet T64 turned up eventually sporting - you guessed it - fiberglass sandwich armor bow! My my, whotta coincidence!

Another visual difference between M48 and M60 are the cast aluminum roadwheels nstead of steel on the M48. The M60 cast wheels are distinguished by reinforcing ribs running around the outside bead. Pretty late in M60's career they reverted back to steel wheels again.

In these shots of the Fort Irwin M48 and M60A3, you can see the difference in the return rollers, and the front leading edge of the hulls.

The only thing you can really count on is the shape of the hull, for all the reasons listed by the 'Weed. At a glance, if it isn't the A5, the gun is the quick way...unless it's been upgunned, as was often done (Israelis, too).

I musta' been one of the last AIT classes to train on the M48 in 1971...I've always wondered when that switched over....

Aaahhhh, thanks everyone!

I know a little here and there, but it's never too late to learn a few more things! Smile

Headlight shrouds...forgot the headlight shrouds (and these might be the same on the A5...gotta' check).

Actually the turret for the early M60 (A-nuthin') is slightly different than the M48 turrets. The back end of the turret is more squared off than is the M48 turrets. Below is a picture of the AEF M60 early turret conversion as compared to the Academy M48A5 turret. The differences check out when looking in Hunnicut's Patton book (a great reference if you can get one).

Looks like the other main differences have been addressed by the others already...

Hi Folks!

One more item that helps, no matter which direction the point of view is from as long as it can be seen.

The TC's cupola!
All the 48 cupolas are much smaller and mounted a M2HB machine gun.
All the 60 cupolas are much bigger and mounted the M85 machine gun.

Spot Report!

...and both were next to useless.

ThatÃ¢â‚¬â„¢s was a really good question,
What really throws a wrench in the works is the ability to interchange the turret between the two. BDAR manuals at the time outlined the ability to do just that. The rings diameters were the same. There are 48Ã¢â‚¬â„¢s with 60 turrets and 60Ã¢â‚¬â„¢s with 48 turrets. They are mostly Non-US models. Taiwan has put modified 48 turrets (LRF/STAB/Thermal) on surplus 60 hulls they got from the US. I think they call them CM-11Ã¢â‚¬â„¢s. Get's very confusing. As far as US models here are the simple ways I tell the difference, all are 90mm except A4/A5.

M48, Open cupola, 5 support rollers, gas powered with exhaust center deck, small drivers hatch.
M48A1, M1 closed cupola with M2 TT .50cal, same deck/gas, 5 support rollers, large drivers hatch.
M48A2, Same cupola, new low IR deck with rear grills, gas powered, 3 support rollers.
M48A2C, Same as above but has newer Fire Control system. Longer bore evacuator.
M48A3, Rebuilt 48/48A1, has new IR deck, turret same as A2C, uses M60 components, Diesel engine, also has air cleaner boxes like the M60. 5 support rollers. Some have vision block ring installed between M1 cupola and turret. The prototype of this used an A2 model so it had 3 support rollers.
M48A4, Experiment, Used old straight 60/105mm turrets left over from A2 production. Has the same hull as A3. Cupola is the M19 with M85 .50 cal. Project cancelled.
M48A5, M48A3 up gunned with M68 105 cannon. All IÃ¢â‚¬â„¢ve ever seen had low profile cupolas (Israeli?).

They also took an M60 and mounted an M48A5 turret to it. I believe Fort Knox has it. Then you have the oddities created for hard targets. The idea is if it fits, put it together. IÃ¢â‚¬â„¢ve seen M60A2 turrets on 48A1 hulls. None of these creations were operational, just an easy way to make targets.

DifferenceÃ¢â‚¬â„¢s between 48 and straight 60 turret.

M60 has M19 cupola with M85 MG. ItÃ¢â‚¬â„¢s much bigger.
M60 has rear stowage mount for M2 .50 cal.
M60 turret has a more squared right rear. (Like models shown)
M60 base for cupola is larger, sits higher and has a slot cut at the 3 and 6 oÃ¢â‚¬â„¢clock position.

Please chime if thereÃ¢â‚¬â„¢s anything to add or correct, I donÃ¢â‚¬â„¢t have my references. My rule of thumb is the hull determines the tank, boat shape front = M48, Flat M60. But that's me.

Hope this helps. Thanks for the vote of confidence Dontos and Doug, I still liked my M85, lot's of places to store pogey bait in the ammo box.

WOW! I guess there really aren't any stupid questions!

Thanks guys ... I can now consider myself well informed!

I knew you'd be up to it. Two things:

M60 hull with M48 turret is in fact in the collection. Damn thing looks brand new. It is a prototype M60.

M48 chassis mounted with M60A2 turret is up on Zussman Range (MOUT site). I've seen it a number of times. The turret has some remote operability when the full system is used for a training unit. Its between the 'school' and the water tower.

Isn't there an tension adjusting arm w/roller between the last roadwheel and the sproket? (M48A?)

Hi Joe...
I was thinking primarily of the cupolas....neither was very wieldy...which is why flex-mounts got stuck on them in real-world conflicts. M85 was a hoot, when it was working right.

Joe_D · Posted: Fri Feb 10, 2006 1:29 am Post subject: Re: M48 vs M60

Hey Dontos,
I figured you'd be trolling around tonight. The early 48's (pre-diesel) had the stupid little wheel between the sprocket and #6 road wheel, Just like the 47's. A lot got cut off later in their life on both of them. Usually you can see what's left of the arm still on the hull. It had it's own torsion bar from what I remember. The 47's we got back from France and Italy usually had them removed and plated over. The ROK Army 47's also had them removed. I can't say for sure but I believe it became useless when they started using a newer front idler system. That's why it's called the "Compensating Idler Wheel" because it moves forward as the track compresses the #1 arm up. I don't think 47's and early 48's had this system. Someone out there might know.
Dontos, If I ever find my way back to Knox, I'd like to see the 60 with 48 turret. Of coarse I'd bring my camera. The 48 hull I seen with the 60A2 turret was at the recovery school range across from Muldraugh. (GMD range??) there at Knox and I also saw one sitting in Richardson tank park in 97 I think.

Hi, Doug!

Funny; if you were one of the last AIT classes to train on M48s, I might have been among the first classes to train on M48's AND slick M60s, at fort Knox, Summer, 1962. Night and day, brother, what a difference! Especially in the driver's compartment -- like going from Corvair to Oldsmobile. Exactly ten years' difference. The M48s must have seemed like Ford Model As or something to you guys by that time ("Hey, Cletus, looky-here, there's a dadburn horn on this'n! Beep-beep!"),

With that diesel pack shaping the after hull, the M60 always looked 'tall-in-the saddle' to me, compared with the much-squattier 'bathtub-shaped' after hull of the gasoline pack-equipped M48 versions.

The gasoline M48 also had, to some, a 'trumpet' tone out of those mufflerless exhaust headers at various loads and throttle applications, and if backing down suddenly was needed, as in an emergency stop, those headers belched raw gasoline flame like a Lockheed Constellation at takeoff.

As many of you guys have mentioned, the bore evacuator, or fume extractor, was at the very end of the M48 main armament, but only if it was fitted with the 90mm gun.

Early M48s had a little tensioning idler between the trailing roadwheel and the drive sprocket, but these, along with the horn, disappeared in the early sixties, at least in FRG.

That toad-shaped face of the M48 glacis is the surest giveaway of all.

Sincerely, sniff,
Russ
