Unsourced material may be challenged and removed. It australian welding standards pdf the primary tank used by the Italians throughout the war. Italian tank weight standards at the time, 13 tonnes was the scheduled weight and 1940 the initial year of production.

The crew of four were housed in a forward fighting compartment, with the engine at the rear and transmission at the front. The tracks were conventional skeleton steel plate links, and were relatively narrow. Together, this system was thought to allow good mobility in the mountainous areas in which future combat was expected. In the desert where most M13s were actually employed, mobility was less satisfactory. This was an innovation that many countries had yet to introduce, as diesel engines were the future for tanks, with lower cost, greater range and reduced danger of fire compared to petrol engines. One hundred and four rounds of mixed armour-piercing and high explosive ammunition were carried.

A fourth machine gun was sometimes carried in a flexible mount on the turret roof for anti-aircraft use. RF1CA radio was also fitted as standard equipment. 70 a month, before the fall of 1940. Further action took place in Derna, where the V battalion had just arrived. Italian troops to retreat along the Libyan coast. The attacks failed and all of their tanks were lost. The last six surviving tanks entered a field near the local British command post.

Many tanks were lost in this campaign to artillery fire rather than other tanks. 1941, when their fuel ran out and they were destroyed. Italians had around 240 M13 and M14 tanks in first-line service. 230 M13s were still in front line service. 50 mm calibre only during 1942. The adoption of the 47 mm long gun was probably the best feature of the M13. The diesel engine was an advantage, and the simplicity of production suited the state of Italian industry.

However, the tank also had many grave shortcomings which severely hampered its effectiveness on the battlefield: the engine provided good range, but not great power and reliability. The M13’s engine was the same as the M11’s, but the newer tank was heavier, which resulted in lower speed and more strain on the powerplant. The suspension and tracks were reliable, but resulted in relatively low speeds, not much better than infantry tanks such as the Matilda. 41 but did not keep up with the increased armour and firepower on Allied or German tanks. The method of construction, using rivets, was outdated.

Most tanks of the era were switching to the use of welding for construction, since rivets can shear off when hit, becoming additional projectiles inside the tank. The two-man turret was less efficient in combat than the three-man turrets used in many other tanks of the era. Radios were not fitted to many tanks. Italian crews improved during the conflict, their tanks’ technical disadvantage worsened. In such a condition, they marvel that the Italian tanks were able to fight for as long as they did. Despite heavy operational attrition, the M13 were present at the war’s end and a few even managed to survive into the post-war period. It was equipped with a more powerful engine as well as better air filters for operations in North Africa.

It also had thicker armour than the previous models. 40 tank with the turret replaced by a large multi-piece hatch. The hull housed additional radios and other communication equipment.
