Up to 4000 armored military vehicles by November 1943


Genesis of Italian armor

Fiat 2000
Like other nations involved, Italian tank development dates back from WW1. They observed Allied efforts in 1916, and the first successes in the field. However, the Italian view on armored warfare was limited in scope, mostly because of the landscape where most divisions fought. The Austro-Hungarian border was mostly an Alpine battleground, which prevented any efficient use of tanks. However, in some areas, like Northern Dalmatia, tanks were ideally suited. The general staff ordered a single French Schneider CA-1 in 1916, for extensive trials. But the design was ultimately rejected. A similar indigenous model was started the same year when FIAT, by then the industrial giant of Italy, proposed a new design, the FIAT 2000. It was ordered after the plans were drawn up, and the construction of two prototypes soon began. It was a 40 ton boxy model, which bore some superficial resemblance to the German Sturmpanzerwagen A7V. It never entered production, as the war came to an end. It had innovative features, like a completely separated engine compartment, with the crew being posted above. One of these two machines was operationally tested in Libya, and the other displayed in several propaganda shows.

From 1927 to the Ethiopian invasion

By 1918, FIAT and Ansaldo were the only industrial complexes large enough to deal with tank production. The first model produced for the Royal Army (Regia Esercito) was a local derivative of the French Renault FT, called FIAT 3000. These vehicles were ready in 1922, and served well to forge Italian interwar armored tactics. A variant developed in 1930, armed with the Vickers-Termi 37 mm (1.46 in) gun, named FIAT 3000B. Both formed the bulk of the Italian army corp, until new models arrived in 1935. From there on, official designations incorporated “Carro Armato or “CA”, meaning “armored carriage” and an abbreviation composed of the army model designation( L for “Leggera”, M for “Medio”, P for “Pesante”), the weight and the year of first production.

The FIAT 3000B (later L5/30) was an important step towards full-scale tank production. But only 153 were built in all, and they never achieved all the expectations placed on them. Despite this, some were exported, including to Eritrea, and others fought during the second Italian-Ethiopian war of 1935. They also soldiered in East Africa, in the Balkans and Greece, and still operated in 1943, when the Allies landed in Sicily, at Gela.

Italian tank development during the thirties

In 1928, an Italian army commission attended the first public demonstrations of the British fast one-man tankette designed by Major Giffard LeQuesne, which later became the first Carden-Loyd tankette design. The Mk.VI, distributed by Vickers, was an instant success, sold and produced under licence abroad. It was fast, versatile, and cheap. The tankette fad lasted well until 1936. Ansaldo and FIAT earned contracts for the first Italian design, the CV-33 (“Carro Veloce”). It was followed by the CV-35, and the CV-38. These were the most produced armored vehicles in Italy so far, being an export success and even cheaper than the original Vickers model. Accordingly, these tankettes saw extensive service, despite being obsolete by 1940.

World War Two light Italian armor

Carro Armato L6/40
By June 1940, the bulk of the Regio Esercito armored forces was made of tankettes. These had several limitations, like weak protection, machine-gun armament, and no traversing turret, which all prevented any use against other tanks. This issue was first addressed with a prototype, the FIAT-Ansaldo Carro d’Assalto L/36 or 5-tons modello 36, a CV-35 tankette equipped with a new suspension and a light traversing turret, armed with a L/26 37 mm (1.46 in) and a coaxial Breda 6.5 mm (0.25 in) machine-gun. The armor was raised to 30 mm (1.18 in), speed lowered to 32 km/h (20 mph) and the range was only 80 km (50 km). A second prototype had the gun placed in the hull, and a fully traversible light machine-gun turret.
Despite some production advantages, the Army choose a new scaled-up model. The Carro Armato Leggera M6T (1938) was given a stronger chassis, more powerful SPA 8-cyl engine, a reworked suspension, and a light turret bearing twin 8 mm (0.31 in) Breda modello 38 machine-guns. It has an impressive 42 km/h (26 mph) top speed and far better range (200 km/125 mi). But despite these performances, the Army insisted for a better armed model. Thus, the L6/40 appeared in early 1940. The first prototype and a preseries were delivered by mid-1940. The L6/40 was almost identical to the previous prototype, but with a 20 mm (0.79 in) 37/26 rapid-fire antitank gun, and a coaxial Breda 8 mm (0.31 in). The preseries and series were armed with a Modelo 35 gun. The L6/40 was fast, but it was barely more than an improved tankette, weighing 6.8 tons in battle order.

World War Two Italian medium tanks

The need for a medium infantry tank urged FIAT and Ansaldo to design a brand new hull in 1938. Army specifications included a 37 mm (1.46 in) gun, two machine-guns and good armor. At first, the M11/39 came with strong influences from the British Vickers Matilda I and Cruiser I. But still, there was no turret design strong enough to support the designed M40 37 mm (1.46 in) gun, and it was fitted in the hull. The light turret was equipped with twin Breda 8 mm (0.31 in) machine-guns. For the first time the crew consisted of three-men. The armor was 30 mm (1.18 in) thick, and the engine was a 105 bhp V6 diesel, sufficient to give a maximum speed of 32 km/h (20 mph) and 200 km (124 mi) range. It was a 11-ton model, hence its denomination. The next step was the M13/40, a 13-14 ton medium tank fitted with a gun turret (47 mm/1.85 in Cannone da 47/32 M35) and a four-men crew. This gun had some armor-piercing capabilities.

After a single prototype, a series began in late 1940. Later production versions (1941) had 42 mm (1.65 in) of armor, similar to the next model, the M14/41, which was almost identical. The last evolution of the type was the M15/42, equipped with a much powerful petrol engine, the FIAT SPA 145 bhp. But all these designs were limited by a rather obsolete suspension system, dating back to the Vickers 6-ton. Starting in 1942, the Italian army tried to develop a true “cruiser tank”. This could only be achieved with a Christie style suspensions system. This led to the M16/43, better known as the Carro Celere Sahariano, which bears some resemblance to the British Crusader. It had a very low profile, long hull, and the same armament as before, probably 40 mm (1.57 in) of armor, and a powerful FIAT SPA (275 hp) engine. It was capable of a sustained speed of 71 km/h (44 mph). But it also came too late. Production was cancelled as the Axis was driven out of Tunisia.

Italian heavy tanks

Since the WW1 FIAT 2000, no heavy model was ever studied, mostly due to the lack of funds, industrial capabilities or different priorities. However, this changed in 1939, with some German assistance. The Carro Armato Pesante P26/40 was equipped with a powerful 420 hp FIAT V12 diesel, and had a welded hull protected with 50-60 mm (1.97-2.36 in) of hardened steel armor. The large two-man turret housed an efficient 75 mm (2.95 in) L/34 gun. which had good armor-piercing capabilities. Because of the lack of resources, the first prototype was not ready before 1942, and production really started in 1943. By November, only 70-80 had been delivered. Production was then taken over by the new German authorities, and ultimately 103 would be completed. Most served with the Wehrmacht in Italy, until the armistice.

Light tanks

Light tanks were developed first, like many other nations in the 1920s and 1930s. France provided the first tanks in the shape of the wartime Renault FT, which Italy copied and refined as the FIAT 3000, and later adopted the British Carden Loyd tankette concept. Tankettes, although of limited value on the battlefield, were cost-effective and cheap to produce en masse, enough for filling reviews and for Mussolini to boast of his power to foreign journalists not keen on military matters. But, as it was learnt the hard way in Africa, these vehicles were easy prey and were only suitable for scouting and as auxiliaries. Nevertheless, they provided the precious industrial experience basis upon which the Italian medium tanks were developed.

L5/21 – 100 units, light infantry tank, designed in 1919, armed with twin Breda 6.5 mm (0.25 in) machine-guns.
L5/30 – 52 units, light infantry tank, modified in 1930, armed with a single 37 mm (1.46 in) and a coaxial 6.5 mm (0.25 in) machine-gun.
L3/33 – 1200 units, tankette, twin Breda 7.9 mm (0.31 in) machine-guns.
L3/35 – 1300 units, improved tankette, twin Breda 7.9 mm (0.31 in) machine-guns.
L3/38 – 200 units, upgraded tankette with a new suspension system, twin Breda 7.9 mm (0.31 in) machine-guns.
L6/40 – 283 units, new light tank, one 20 mm (0.79 in) gun and a coaxial Breda 8 mm (0.31 in). Several derivatives.

Medium tanks

Medium tanks (Carro Armato Medio) were first developed as scaled-up tankettes or after the example of the British Mark E. After a first small series of stopgap vehicles armed with a hull main gun (a solution also favored by France and USA), the bulk of the production was centered around a homogeneous series, the M13/40 and its successors, which were very closely related. Together, they formed a 1800-strong tank force, quite an achievement for Italy at that time, but certainly not impressive compared to the industrial muscle of Great Britain, moreover the United States. Although their protection was relatively strong, the bolted assembly denied this advantage. Firepower was adequate, with a very good 47 mm (1.85 in) gun and a tandem of machine-guns, but their diesel engines suffered from the heat in North Africa, and their old-fashioned suspensions did not favored the great speeds required in desert warfare.

M11/39 100 units – 37 mm (1.46 in) Vickers-Termi gun in the hull and twin Breda 8 mm (0.31 in) machine-guns in the turret.
M13/40 779 units – 45 mm (1.77 in) Breda gun in the turret and twin Breda 8 mm (0.31 in) machine-guns in the hull, better engine and armor.
M14/41 800 units – 45 mm (1.77 in) Breda gun in the turret and twin Breda 8 mm (0.31 in) machine-guns in the hull.
M15/42 118 units – same characteristics, but better armor.
M16/43 prototype only – the “corazzate”, an Italian fast cruiser tank with Christie style suspensions.

Heavy tanks

Due to progressive technological advances in manufacturing, Italy started building a heavy tank in 1942 (not counting the early FIAT 2000), with German engineering help. Built in small quantities and too late, this excellent tank was mostly used by German crews after the Italian armistice.

Carrro Armato Pesante P26/40 103 units – 75 mm (2.95 in) armed, good armor. Developed too late.

Tank destroyers & SPGs

Under the name “Semovente”, Italian self propelled guns were inspired by the success of the German StuG III on the Eastern front. A wide variety of these tanks were derived chiefly from the standard medium tank chassis, and the light tank L6 as well. Their names (Semovente means “self propelled”) were composed of the main gun’s caliber followed by its barrel length ratio. Ex. 75/18 meant 75 mm – 18 caliber (the barrel length was 18x the bore diameter).

Semovente da 47/32 – the lightest of the series, built on the L6/40 chassis, with a 47 mm (1.85 in) AT gun.
Semovente da 75/18 – the regular SPG inspired by the StuG III, based on the M13/40 and M14/41.
Semovente da 75/34 – a tank hunter based on the M15/42 chassis.
Semovente da 75/46 – tank hunter based on the M15/42 model 1943 chassis, mostly used by German forces.
Semovente da 90/53 – formidable tank hunter equipped with a 90 mm (3.54 in) converted AA gun.
Semovente da 105/25 – the heaviest and last tank hunter, based on a widened M15/42 chassis.

Armored cars

Although these kind of vehicles gave speed and firepower at affordable cost, Italy did not develop the concept of armored cars (AutoBlinda or AB) as much as the British Forces, especially in North Africa. The IZM and AB611 were old and heavy machines, unsuitable for reconnaissance. However, after 1940, the AB 40 series provided the bulk of Italian armored cars with an excellent model, declined into the AB 41 and AB 43. British models were found as a source of inspiration, the LRDG operations inspiring the AS 42, while the Lince was a copy of the Daimler Dingo.

Lancia-Ansaldo IZM – only a handful of these WW1-era armored cars were used in Colonial areas.
Autoblinda Fiat AB 611 – the standard late 1930 4×6 colonial armored car.
Autoblinda AB 41 – a rather successful 4×4, well-armed design, which strove in North Africa.
Camioneta AS 42 – a conversion of the AB 41 as a long range vehicle equivalent to the British LRDG patrol cars. Depending on their posting, these were the “Sahariana” or the “Metropolitana”.
Autoblinda Lince – a copy of the British Daimler Dingo, with 250 copies built in 1943-45 and used by the Italian Social Republic and German Forces.

Ansaldo MIAS

The Ansaldo MIAS or “Motomitragliatrice Blindata d’Assalto” (Armored Engine-driven Assault Machine-gun) was one of the tiniest “tanks” ever built. It was so small that the user had to march behind crouched, although protected by the side extensions of the armor, which were able to stop bullets at 50 m (165 ft). It was propelled by a single-cylinder 250cc Frera engine, which could  produce 5 hp, enough to reach 5 km/h (3 mph), walking speed. However, it also benefited from a reverse gear and a differential gear for rapid direction changes.

It was armed with two 8 mm (0.31 in) Breda machine-guns or a 45 mm (1.77 in) Brixia grenade-launcher. While a tank in appearance, this vehicle was more of a self-propelled shielded machine-gun in reality! It was one of the weirdest vehicles of the 30’s, developed out the of the experience and remembrance of trench warfare. Due to its very low price, it could have been produced by the thousands, but the army choose otherwise and, luckily for their potential users, the CV tankettes were preferred.

FIAT Ansaldo Carro Veloce 33
The CV 33 tankette, the best-seller and most produced armored vehicle in Italy at the time.
Carro Armato L6/40
The L6/40 was the next generation of light tanks, initially developed on the basis of the CV 35 tankette. It had a new suspension system and a 20 mm (0.79 in) gun in a traversing turret. It was the Italian equivalent of the Panzer II.
Carro Armato M11/39
Some M11/39s captured by Australian troops after the British counter-offensive of early 1941. This medium tank was strongly influenced by 1938 British designs, like the Matilda I and Cruiser I.
Carro Armato M13/40
Some M13/40s in maneuvers. This medium tank, derived from the M11/39, spawned a long lineage and was built from 1940 to 1943, in several versions. With 30-42 mm (1.18-1.65 in) of protection and a high-velocity 47 mm (1.85 in) gun, it was the mainstay of Italian armor.
Carro Armato M14/41
A captured M14/41, formerly used by the Wehrmacht to deal with Polish insurgents, here in Warsaw, in 1945. The M14/41 was one of the last evolutions of the M11/39.
Carro Medio Celere M16/43 Sahariano

At the beginning of WW2, Italian armored divisions were equipped almost 90% with L3 tankettes, of dubious combat value, as was shown in the following years. The M11/39 was a good start, although limited by its configuration, but the M13/40 and the following M14/41 and M15/42 were much better, although still hampered by their riveted construction and old fashioned leaf spring bogie suspension, which limited top speed. After the first encounters with British Cruiser tanks, the idea soon emerged of a similar vehicle, in early 1941. Italians engineers did not have access to the Christie suspension patent, so the design was obtained after reverse-engineering a captured Cruiser Mk.III.

Despite a weak armor, speed had a quality of itself, giving a sort of active protection. Since the M13/40 and following models could not match the top speed of the A13 Cruiser Mk.III, an order to start the development of a similar tank was passed, which had to be faster and have a lower silhouette, for colonial duties. As it had to be designed with desert warfare in mind, the FIAT engine’s cooling was reworked, with the introduction of tropical features, like sand filters and a new ventilation system for the crew. First mention of the M16 came from May 24, 1941, when the proposal was formalized by the Commando Supremo and validated by the Roatta Ispettorato Superiore di Studi (Higher Inspection Technical Research).

On June 23, Ansaldo produced a full-scale model of the tank. Work on the intended 47 mm (1.85 in) gun 47/40 long barrel progressed at the same time. In August 1941, the project was upgraded and designated as the Ansaldo-Fossati Carro Medio Celere (later FIAT M16/43). Its most distinctive feature was its four big road wheels suspended by Christie type vertical springs, two return rollers and auxiliary rollers in between. The hull was very elongated, with well sloped front and side plates. The overall empty weight was 13 tons, and there was a crew of four, including the commander, gunner and loader/radio operator located inside the turret. The SPA petrol engine delivered 275 hp, for an estimated top speed of 55 km/h (34 mph) on flat ground. A wooden 1:10 mock-up was presented and construction approved by the Commando Supremo on August 13, 1941. It was already dubbed Sahariano. Despite its revolutionary design, there were still a few anachronisms, like the riveted construction and the main armament, the long-barrel 47 mm (1.85 in) gun 47/40 and coaxial single Breda 8 mm (0.31 in), still relevant compared to the British 2-pounder, but certainly not up to date with the current requirements of the front in mid-1941 and new developments of tank guns.

A 75 mm (2.95 in) gun was studied, but never implemented. Protection was sacrificed, with the greatest thickness (30 mm/1.18 in) on the front slope and 20 mm (0.79 in) on the turret face, figures no longer relevant, as shown by the poor battle performance of the Crusader. As production was delayed, a prototype was built only in the spring of 1942, when M4 Shermans were already equipping the British Armoured units. The Celere Sahariano became outdated, despite tests showing a top speed of 71 km/h (44 mph) was achieved. In July 1942 the project was terminated, as the more conventional M15/42, then in development, was given priority. The prototype was kept in storage and scrapped in 1944.
Autoblinda AB42
The Autoblindas AB 40 to 43 were the main armored car in the Regia Esercito. It was a sturdy and well-armed design, with good off-road capabilities.
Semovente 47/32
The Semovente 47/32 was a derivative of the L6/40, strongly influenced by the German StuG design. It was used as a tank hunter, as well as for close infantry support.
Semovente 75/18
The Semovente 75/18 was a self-propelled artillery based on the M11/39, but equipped with a fixed 75 mm (2.95 in) gun.
Semovente 90/53
The Semovente 90/53 was the heaviest adaptation of the M14/41 chassis, and was used as artillery support as well as tank hunting.
Carro Armato P40
The Carro Armato P26/40, the last WWII evolution of Italian tanks, was a good design armed with a high-velocity 75 mm (2.95 in). However, it came too late.
Semovente 75/34
A Semovente 75/34 captured by British troops in 1944.

      The P43 heavy tank never left the design phase. Only photos of a few models exist. It may eventually be treated as a prototype of the week, but there are no plans for that as of yet. If you’d like to see it, perhaps you can provide us with good sources for the tank?
