Danish Army Specific: When entering NATO in 1949, Denmark qualified to be part of the MDAP. As founded by the United States, Denmark had three options in tanks: M4A3 Sherman, M47 and M48. Denmark had the M48 in favour, but because of not being the most important recipient, United States wanted Denmark to have the Sherman.
These different point of views led to deliverance of 8 Sherman's in April 1952, officially for training, but the United States had made their point clear. Denmark then asked for the M47, but as the month went on, it became clear the countries like Korea, Italy and France was in a greater need.
Suddenly the United States offered the British
Centurion Mk III instead, an offer that was accepted.
According to the serial numbers all 8 Sherman's were built as M4A3(105)VVSS, but later converted with a 75 mm turret which had it's M3 gun replaced with a M1A1 76.2 mm gun
The Sherman was the first tank to become operational in Denmark.
Historical
: In April 1941 the Armoured Force Board considered 5 proposals for the new M4 medium tank, and chose the version based on the medium tank M3 Lee. Approval was given in May 1941, a prototype known as the T6 was produced at Aberdeen Proving Ground and ready in September same year. The following month it was standardised as the M4.
At the same time the M3 was downgraded to "Substitute Standard". The Sherman shared many components with the M3 General Lee.
In December the designation M4A1 was assigned to those tanks with a cast upper hull. Production of the M4, which were powered by a Continental R975 Whirlwind radial engine, started at the Lima Locomotive Works in February 1942.
The M4A2, which were also standardised in December 1941, went in production in April 1942. It was essentially a M4 powered by a General Motors 6046 twin diesel engine, rather than the Continental 975 petrol engine.
The M4A3, which were standardised in January 1942, differed from the A2 mainly in the design of the turret and suspension (Horizontal Volute Suspension System (HVSS) versus Vertical Volute Suspension System (VVSS)). The Ford GAA-III engine was developed especially for the M4A3 version. First production vehicle was completed by Ford in May 1942.
The first M4A4 was standardised in February 1942 and went into production by Chrysler in June. This version was powered by the 30-cylinder A57 multi-bank engine, and most of the production were supplied to the British under Lend-lease.
A M4A6 was produced by Chrysler at the Detroit Arsenal from October 1943, but in February, after only 75 of the planned 775 vehicles had been produced, production ceased. The A6 version was basically a M4A4, but powered by a RD 1820 radial diesel engine built by Caterpillar as their model D200A. The engine was based on the Wright G200 aircraft engine.
Various version such as mine flail, bulldozers and flame-throwers were made.
Besides WW II the Sherman served the US Army through the Korea War, and several thousands were supplied to other nations in military aid programs.
The Sherman was declared obsolete by the US Army in 1956.
