Apparently the cannons at Ft Will and Aberdeen still have the Mack T9 with the cannon, supposedly 20 were built and were fielded in Europe and Korea during the cold war.

Ft. Sill, and they are modified or updated T9's with different 375hp engines and std Mil Spec heavy truck wheels and tires for parts commonality.

More research shows that the M249 front and M250 rear tractors for the M65 cannon system were actually KW's, the Macks were used to start the project and KW built 33 pairs of the tractors for the cannons when they were put into service. Seems odd KW built 33 pairs and they supposedly only built 20 cannons and the tractors are harder to find than the cannons but crazier things have happened.

Speaking of the Kenworth-produced M249 (front unit) and M250 (rear unit), we're talking about the T10 (the gun it carried was designated M65/T131). While it is reported that only 20 of the atomic cannons* were produced, noted military vehicle historian Fred Crismon states that sixty-six of the 85 ton T10 gun carriages were produced in 1952-1953, and many were stationed in West Germany from 1954 to 1961.

Each unit was powered by an 895 cu.in. 375 horsepower Continental A0-895-4 horizontal opposed-piston engine coupled to a 3-speed manual transmission with an Allison torque converter.

As with the Mack T8 Series, the forward driver controlled both power and brakes.

* The cannon could fire both conventional and W9 atomic shells. It had a range of 35 miles with an accuracy of 20 yards. The 280mm cannon was based on the German Krupp K5 railway gun captured by the Allies at the end of WW2. Twenty eight were produced and two nicknamed "Anzio Annie" and "Anzio Express" by Allied troops made quite an impression in January 1944 when they began shelling the Anzio beachhead during Allied invasion of Italy from 20 miles away. The Allies again felt the lethal end of the German 280mm K5 cannon in June 1944 during the invasion of France.

A little known fact is the successful firing of a W9 nuclear shell in Nevada in 1953 is credited with bringing an end to the Korean war.

Been to Aberdeen a lot and there's stuff all over that place. Just never allowed to stop and take pics. Go figure.

A lot of the referbished armor and weaponry has been moved to Fort Lee, Virginia, some is on loan to The American Armor Museum in Virginia a few tranport vehicles were loaned to the U.S. Army Ground Transport Museum in Virginia and some of the WWII German Armor is on permanant loan the the German Armor Museum in Munster, Germany. What it left there is not money to "sanitize" it per new EPA regulations for Lead, Asbestos and Depleted Uranium contamination of the Iraqi vehicles. . .SAD

Great article,thanks for posting! I have always been interested in WWII,and its many vehicles,and always wondered about the operation of tanks and their crews,i found this video on the driving of a Sherman M-4 I thought might be of interest. For those un-aware,the Sherman was a highly inferior tank to comparable German units,basicly a deathtrap! under-armored,under-gunned,and fueled with high-octane gasoline. But Mack did make the transmissions for both early M-3 and M-4's musta' been quite a workout to run a tank! I give the WWII tank crew vets all the admiration and respect I have! Truly some of the most un-sung heroes of the war...........................Mark

Note that the Sherman on the Mack T8E1 is a late model with HVSS suspension (horizontal volute spring suspension) and the 76mm high velocity gun.

The Shermans evolved into a formidable weapon as a result of British modifications. The Brits needed more tanks but recognized the Sherman's deficiencies that you speak of (The British were well aware of the weakness of U.S. tank design, having already suffered heavy losses with U.S. M3 "Grants" against Rommel's Afrika Korps). The most important British modification was replacement of the short 75mm cannon with a lethal long barreled 17-pounder anti-tank gun that could take on most German armor. It could penetrate more armor than the 88mm in the German Tiger.

England operated 17,184 Shermans. Unlike gasoline-engined U.S. Arrmy Shermans which earned the name "Ronson Lighters", many British Shermans received under Lend-Lease had 410 horsepower Detroit Diesel model 6046 12-cylinder engines, essentially two paired 6-71 engines (Sherman Mark III/M4A2). The Russians, whose tanks were all diesels, received M4A2s as well. The U.S. Marines did receive a few M4A2s (less than 200) for use in the Pacific alongside gasoline-powered M4A3s.

A small volume of Lend-Lease Shermans (M4A6) were fitted with 450 horsepower RD-1820 radial diesel engines, a Wright R-1820 aircraft engine converted to diesel by Caterpillar.

Mid-way thru the war, U.S. Army Shermans were upgraded with the heavier T23 turret and a 76mm high velocity gun, giving our guys a chance (but still unequal to the British Sherman "Firefly" variant).

With its early weaknesses resolved, the refined M51 Super Sherman was being used successfully against significantly more modern Russian T54 and T55 tanks as late as 1973 by the Israeli Defense Force.

The Israeli "Super Sherman" mounted a deadly French 105mm Modele F1 gun in a much modified turret, with 460 horspower Cummins VT8-460Bi V-8 engines and HVSS suspension.
