Panzerserra Bunker- Military Scale Models in 1/35 scale: Cruiser Mk I (A9) British tank

Cruiser Mk I (A9) British tank - case report

Tankers of His Majesty !!

The subject of this work is one of the pioneers of Armored Warfare with the English. It fought bravely in the fields of France and in the desert sands, but was quickly surpassed by more modern machines. Today we will learn about the history of the first operational of the Cruisers tanks: the Cruiser Mk.I tank A9.

History

The Tank, Cruiser, Mk I (A9) was a British cruiser tank of the interwar period. It was the first cruiser tank: a fast tank designed to bypass the main enemy lines and engage the enemy's lines of communication, as well as enemy tanks.

The Cruiser Mk.II (A10) was a more heavily armoured adaptation of the Mark I, developed at much the same time.

Design and development

In 1936, the British War Office designated two different kinds of tanks for future development: heavily armoured infantry tanks to be used in close co-operation with infantry during attacks, and fast mobile cruiser tanks designed to make forays deep into enemy territory.

Due to the cost, British replacement designs for Medium Mark II tanks then in service had been cancelled with only three Medium Mark III built. In 1934, Sir John Carden of Vickers-Armstrong was asked to provide a "reasonably cheap tank" as a replacement for some of the medium models then in use. This design was known by General Staff specification A9.

The pilot model of his medium tank design was finished in 1936 and given the designation A9E1. It incorporated the best features of the cancelled Medium Mk III design, but lighter so that it could be powered by a commercial petrol engine.

However, this was still in the time of the Great Depression and the tank had a number of cost-cutting measures applied. It was the first British tank to have a centrally located turret and to have powered traverse. The system was by Nash & Thompson and similar to that being introduced on the Vickers Wellington medium bomber aircraft.

The armour was light, with a maximum thickness of 14 mm (almost a standard for the time). Many armour faces were vertical, and there were numerous shot traps, but it could achieve 40 km/h and carried the new high velocity QF 2-pounder (40 mm) gun, which had replaced the QF 3-pounder (47mm) by the time manufacture started in 1937.

The driver's compartment and the fighting compartments were not separated. As well as the turret armament, which consisted of an Ordnance QF 2 pounder gun and a coaxial Vickers machine gun, there were two small turrets either side of the driver's compartment, each with an armoured Vickers machine-gun.

Both of these smaller turrets were permanently manned, which gave the tank a total crew of six (commander, gunner, loader, driver and two machine-gunners).

The prototype A9E1 was tested against other designs and, although lacking in some areas, it was accepted in 1937 as an interim design until a Christie suspension cruiser tank could be delivered.

An order was placed for 125. Seventy-five were built by Harland and Wolff, and the other 50 were built by Vickers. Initially, a Rolls-Royce car engine (the 7.67 litre of the Phantom II) was used for the pilot model, but this proved to be underpowered and was replaced by a 9.64 litre AEC bus engine.

The later Valentine infantry tank essentially used the same lower hull and suspension, though with considerably more armour.

The A9 weighed 12 long tons (12 t), was 5.8 m long, 2.65 m high, 2.5 m wide and had a top speed of 40 km/h on road and 24 km/h off. Its maximum road range was 240 km. The ammunition load was 100 rounds for the main gun and 3,000 rounds for the three machine guns.

Service

The Mark I cruiser began to be delivered in January 1939. 36 tanks were delivered before the start of the war, 40 in September–December 1939 and 49 in 1940.

The Cruiser was an effective operational tank in the French, Greek and early North African campaigns. They fought intensely and bravely in these Theaters of Operations, but soon became obsolete in the face of better armed, armored and powerful German vehicles.

The 2-pounder gun was lethal against the early Italian tanks encountered during the North African campaign and could hold its own against Rommel's early Panzer IIs and Panzer IIIs.

It could also breach the 20 - 30 mm of protective steel on later opponents, such as the Panzer III Ausf F and the Panzer IV Ausf D.

It was effective until the Germans introduced the more thickly armoured Panzer IV Ausf E to the desert in the spring of 1941.

However, its minimal armour made the A9 very vulnerable to most Axis anti-tank weapons. Also problematic was the lack of high explosive shells for the 2-pounder gun, and even worse the lack of armour-piercing shells for the 94 mm gun on the CS (close support) version. Another issue was that the areas around the front machine gun turrets created a frontal surface that was more vulnerable to enemy fire than it would have been had it been a simple flat plate.

The mechanical unreliability of the Cruiser was also a disadvantage. In particular, tracks were easily slewed, causing difficulties. But these machines fought well and generally performed well, although they were quickly surpassed by the rapid evolution of German tanks and AT guns. On the front line, they became rare from the end of 1941.

Variants

Mark I (A9): Used by the 1st Armoured Division in the Battle of France (1940). Used by the 2nd and 7th Armoured Divisions in North Africa until 1941.
Mark I CS: Had a 3.7 inch (94 mm) /L15 breech-loaded howitzer, derived from the World War I QF 3.7-inch mountain howitzer, instead of the 2-pounder gun. 40 rounds, mostly smoke, were carried.

Surviving vehicles:

Only two specimens are known:

The kit

For this project, we will use the excellent Bronco kit (#35149) Cruiser Tank Mk.I/I CS, which has the option of being built in two versions: the one armed with the 2-pdr AT gun and the one with the 6-inch howitzer, in the CS version. My choice will be the version armed with the 2-pdr AT gun.

Ready for painting...

I will follow the manufacturer's painting suggestion, as my client opted for the Caunter Scheme and the historical references provided by the decal sheet are correct Very well done, Bronco!!!). I redid the colored profile art following the Panzerserra Bunker pattern. Meet ANTELOPE, a Cruiser Mk.I A9 tank belonging to 7th Armoured Division, 1st Royal Tank Regiment, A Squadron, who fought at Derna Pass, Libya, in April, 1941.

I'll be using a Caunter Scheme paint kit from AK Real Colors: Portland Stone, Silver Grey and Slate. First of all, let's paint the kit with the color Portland Stone, following the pattern above:

Portland Stone in the indicated areas...

Portland Stone color: left view

Now, let's isolate the areas in Portland Stone so we can apply the Silver Grey color. In this type of camouflage, I always apply the colors from light to dark...

I'm going to use a small detail from Value Gear to highlight the model... but it's important that the roll bag doesn't interfere with the rotation of the tower... You never know where the danger might come from...

I carved a groove in the ventral portion of the resin roll bags
to fit the hinges on the tank's toolbox...

Everything to avoid interfering with the turret's derivation...

And the roll bags after being painted and installed on the toolbox...

Notice the water can in the turret's side

and to 7 o'clock. Perfect!!

And no English vehicle in the desert would be complete without its signal flags on the radio antenna: tracing paper painted (on both sides) in the desired colors... Detail: before painting, I folded the paper and made a clear crease, so that we could then cut the pennants more easily and correctly, without the risk of "scratching" the paint when folding the pennants...

The creased and painted tracing paper...
Now, just wait for it to dry.

Once dry, we fold the paper at the crease and cut the paper into the desired shape...
Then, just glue the pennants with PVA glue, including the antenna
in the crease of the pennant... Easy!
