Vickers wheel-track tanks

Post by BIGpanzer » 23 Feb 2005 20:53

Also try to find any additional info about this tank.....
Image

This is an experimental British wheel-track tank Vickers mod. 1926 based on Mk.I medium tank design(weight 7.6 t; crew 3 men; armament - 2 MGs; armor 8-12 mm; engine Meadows 135 hp; speed 24-72 km/h) with high-speed engine-gearbox switching between tracks/wheels. The system worked but the crew considered the ride to be unpleasant, also all the external devices on the vehicle were considered vulnerable to hostile fire. Several (~ four) different wheel-track tanks were constructed by Vickers in 1926-1927.

If you know some info about British Martel tankette and Czech KH-50 (KH-60, KH-70) wheel-track tanks, also about Vickers wheel-track tanks, were developed in 1920s, post it here, please.
Thanks in advance, BIGpanzer

About the T-28. I don´t believe it was the most heaviest. If I remember correctly the heaviest tank of WWII was pzkfw. VII Maus with 188 ton.

Hi!
When I wrote about the American T28 as the most heavy tank (or self-propelled gun) of WWII, I mean the tanks of the Allies. So sorry for misunderstanding :) Also the experimental British heavy tank TOG 2 (with 81,345 t) and British heavy assault tank "Tortoise" (with 79,345 t) should be mentioned.
Of course, German super-heavy tank Type 205 "Maus" with ~188 t (or 180 t according to another sources) was the heaviest of WWII. Unfortunately (and fortunately to the allies :) ), never used. I think that the most heavy track vehicle, really used in WWII, was Mörsergerät 040 Karl (120 t).

Soviet wheel-track medium tank T-29

Post by BIGpanzer » 24 Feb 2005 12:55

Also one question: what was the most high-speed tank of 1930s-1940s? Seems to be the Christie models M1937 and
M1938 (on wheels up to 115 km/h!), how do you think? But what about the real track tanks? Of course, I mean test speed on the road, because the max. speed of all tanks at the battlefield is near 20-25 km/h usually :)

Interesting, that one of the most high-speed (and the most heavy among them!) tanks was the Soviet T-29 (based on 3-turret T-28 medium tank design, weight 23,5 t, armament - 1 x 76,2 mm KT-27 + 5 x MGs DT, crew 5 men, armor 20-30 mm, engine M-17B 500 hp, speed 54 km/h on tracks or 81 km/h on wheels, range 125-250 km). T-29 had six traction road wheels and could move with only one track, which was very important during the combat. But this tank was very complicated and unreliable, so its production was stopped, only 2 serial tanks were produced by Kirov factory in Leningrad (+ 3 prototypes). One T-29 used during the battle at Moscow in 1941, as reported some sources.

Well the MG's used on the Martel's would have been Vickers or Lewis guns, or possiably Hotchkiss's.

Hi, Argus!
Thanks, so all possible British MGs of that time were possible, as I understand :)

By the way, I found some specifications of the British Vickers wheel-track tank, I asked the forum members about it a little bit above. Unfortunately, nobody wants to help :( :(
So what I found - built in 1926; this was the standard medium Mk.I on the wheels; the change of the mover was carried out by engine power during 1 min (for example on Czech KH-type tanks - manually by the crew during 30 minutes). The disadvantages of Vickers - vulnerability of the whole system and lengthwise jolting on the road. Weight - 7,6 t; 3 men; 2 MGs Vickers .303; armor - 8-12mm; engine "Medows", 135 hp; speed - 72 km/h on the wheels, 25 km/h on the tracks.

About MGs on British light tanks. I have one question - could somebody explain me how it was possible to use two MGs (7.71mm Vickers + 12.7mm), located one over another in the turret of Mk.I A4E10, used by UK and India in 1930s as experimental tank? I couldn't imagine the control of them.
Mk.I A4E10 had the weight 4,5 t; 2 men crew; 1x12.6mm MG + 1x7.71mm MG; 12-18 mm armor; 56 hp engine; speed 52 km/h and range 260 km.

Soviet heavy tanks SMK and T-100

Post by BIGpanzer » 27 Feb 2005 12:55

Thanks for the reply, Liluh!
Now I am searching the information about Soviet experimental heavy tanks SMK and T-100, one of the first with shellproof armour. They were the predecessors of the KV heavy tanks and both used during the Winter War with Finland...
If somebody know the info about their using by Soviets in the war against Finland and especially their further fate, let me know, please.

Jeez, that T-100 looks like something a bored modelmaker might have whipped together out of spare parts from a couple of kits.

:lol:

SMK and T-100 Soviet heavy tanks

Post by BIGpanzer » 28 Feb 2005 23:31

Yes, those T-100 looks a little bit strange for me also :) Anyway it was much better than five-turret heavy tank T-35 with only 20-30 mm armor (T-35 was produced in 1934-1939). Probably, T-100 was the best heavy tank in 1939.

What I found about Soviet experimental heavy tanks with shellproof armor: SMK (engineer - Ermolaev) and T-100 (engineers - Ginzburg and Palej). Both had two turrets for concentrated round fire (at first three turrets were planned and the design of T-35 heavy tank, but the engineers realized that such tanks with thick armor will be very overweight). SMK means S.M. Kirov - the first secretary of the Leningrad Communist Party Committee, was killed in 1934 by terrorist, according to secret Stalin's order. SMK and T-100 were built in 1939.

Armament and armor were the same in both cases, but SMK had the torsion individual suspension with internal amortization and wide tracks. T-100 had laminated springs.
Both tanks had large weight, hard driving and quite bad maneuverability, gasoline engine instead diesel, and the commander control of the fire from the two turrets was not easy, so they were not accepted by the army. Single SMK was produced, and two T-100 (the second was rebuilt as the heavy self-propelled gun SU-100Y with the navy 130-mm gun). SMK and T-100 were equipped with aircraft engine GAM.

So the main heavy tank of USSR in 1941 was famous KV-type tank (with single turret and short-cut SMK chassis, up to 75mm armor).

Specifications of SMK: weight 55 t; crew 7 men; dimensions 8,75 m x 3,36 m x 3,35 m; armament 1 x 76,2mm gun L-11 (150 shells) + 1 x 45mm gun M1932 (300 shells) + 3-4 x 7,62mm MGs (3969 shells); armor up to 60-75 mm; engine GAM-34BT, 12 cylinders, 850 hp; speed 35 km/h; depletion of fuel 600 L/100 km; range 220 km. SMK had a radio station 71-TK-3.

Specifications of T-100: weight 58 t; crew 8 men; dimensions 8,50 m x 3,40 m x 3,42 m; armament 1 x 76,2mm gun L-10 (150 shells) + 1 x 45mm gun M1932 (393 shells) + 3 x 7,62mm MGs (4284 shells); armor up to 60 mm; engine GAM-34BT, 12 cylinders, 850 hp; speed 32 km/h; range 200 km. T-100 had a radio station 71-TK-3.

Single SMK and both T-100 and SU-100Y were used during Winter War against Mannerheim fortifying line since 18 December 1939 (as the heavy tank company with two additional new experimental KV tanks, 91st tank battalion, 20th heavy tank division, equipped with T-28 three-turret medium tanks). New heavy tanks were invulnerable for 37-47mm AT guns (got many hits without any damage) and achieved good results. Later SMK was blown up on Finnish land-mine at Finnish territory and was left by its crew because of the caterpillar damage. T-100 protected damaged SMK for a long time by guns and MGs fire, took the SMK's crew and returned back to the Soviet positions. Soviet and Finnish army engineer units couldn't evacuate the heavy SMK with broken chassis and caterpillar, even used several heavy tractors and several T-28 medium tanks (by Soviets). So only after the end of the Winter War Soviet engineers could take SMK to pieces and delivered it to the tank factory. SMK was not restored and preserved at the tank factory yard till 1950s, when it was scraped. T-100 fought till the end of the war (12 March 1940).

But what happened with T-100 after the Winter War, I couldn't find. Probably, it was take into pieces at tank factory, but this is only my supposition.
Does anybody know something about this?

Swedish Landsverk L-30 and L-80 wheel-track tanks

Post by BIGpanzer » 02 Mar 2005 10:34

I am trying to find some info about the trials and "further fate" of the Swedish Landsverk L-30 and L-80 tanks, developed in 1931-1933.
Could anybody help me?
