Articles overview
The typical british murder (Dieppe landing)
The main events of Operation Jubilee took piace on Dieppe beach. Wouid Essex Scotch and Hamilton infantry with tanks that were landed there capture the town, it wouEd have been a great success. However, nothing went according to plan.
The air-deployed smoke screen was carried away by the wind. The Germans opened fire on the Canadians, who covered under the pier wall after having landed. Col Labatt's group captured the casino, Cpt Hill's group reached the town center without any resistance but had to turn back for fear of encirclement. But the rest of the command was afraid to show any initiative and didn't dare to advance. Essex Scotch also lost the momentum at the pier and their attack was repulsed.
Tank Sanding didn't fare well either. Landing barges have delivered 30 Churchill tanks. Some of them were knocked out during landing, but the rest attempted to provide support to the infantry. The straps of beach were located where the pier height didn't exceed 60cm, and 13 to 15 tanks advanced on the town. However ail the streets leading into the town were blocked by dragon teeth. Sappers failed to demolish them. The tanks attempted to destroy them with gunfire, but German AT guns opened fire on them, They have broken the tracks of several tanks forcing the rest to retreat. At 7 o'clock it became clear that the landing has failed.
The aftermath of Dieppe raid were not encouraging, Of approximately 6100 men that boarded the ships 3648 were killed, wounded or taken prisoner, including 3363 Canadians, 247 British and 38 Americans. Equipment losses were not as great. One of the eight escort destroyers was Sost, as well as 33 landing craft. Also all 30 landed tanks had to be abandoned. The losses at Dieppe were heavy, but they were heavy only relative to the forces involved, being quite negligible compared to the scale of Allied armies.
During the operations happened what became to be known a typical English murder, when having initiative, recon data and numeric superiority the Allies were conducting the campaign as if they were playing golf, The realities of war however were not exactly in accordance with aristocrat calculations.
Artillery tanks of the Soviet Union
The appearance of this type of tanks in several countries in 1928-1935 didn't come as a surprise. Even back in WW1 the French, while creating their Reno-FTtank, have agreed that the armament of these tanks is too weak to defeat the battlefield strongpoints and decided to produce some of these tanks in the variantot a self'propeiled gun with 47-57mm gun. However these plans were never carried out.
After the war ended the AFV classification got a s!ot for this very type of vehicles, which started being ca!led artillery tanks. The Soviet design efforts on artillery tanks are littie-known. Soviet artillery tanks were meant to carry very powerful armament, 76mm gun, which brought them to the level of heavy tanks armament-wise, Another noticeable feature of the Soviet artillery tanks was the armament placement in a fuliytraversable turret.
The first to design such a weapon system was N.Dyrinkov for his D-3B tank. The turret of this tank was called A-43 and was tested on BT and T-26 tanks. However It proved to be very tight and was not fielded.
Then the time has come for Voroshiiov plant. Here a large turret for T-26 tank was designed. It was tested with PS-3 and KT guns and the tank was damaged in the process. However the turret was noticed by the Kharkov plant Design bureau which adopted it for BT-7 chassis. The resulting tank received the designation BT-7A and 133 were produced. BT-7A tanks took part in the battles of the summer of 1941.
Take off vertically. Or nearly... (two episodes from the autogyro history)
In a flying vehicle caiied the autogyro the lift is produced by a freely rotating main rotor, in-the-aircraft classification they occupy the intermediate place between the planes and the helicopters. They need little space for takeoff, they can move with very small speed without stalling, but they cannot hover. The peak of their popularity happened in 1930s.
The first episode describes the TsAGI efforts to design an autogyro fighter with "Wright-Cyclone" 650hp engine, that was planned to achieve the speed of 300 km/h. New vehicle received the designation A-12 and was built under the supervision of N.Skrzhinsky with the large number of 1-15 and I-16 fighters'parts.
On May 27, 1936 A-12 performed its maiden flight. During trials the speed of 245km/h and the altitude of 5570m was reached. On May 23,1937 the rotor blades fatigue resulted in a catastrophe and the design efforts were abandoned.
The second episode deals with the German Navy use of kite-autogyro Bachstelze, which could fly on a tether around the submarine, aiding it in observation. In USSR this approach was also researched, but the work didn't progress beyond the study of German-supplied documentation and samples.
Heavy German tank A7V
German designers, like their British and French colleagues, had to start from scratch, To supervise the efforts November 13, 1916, the technical commission under General Friedrichs was created.
The view on a concept of a tank varied between War Ministry and High Command. For economy it was decided to develop a unified chassis suitable for a tank, tractor, and truck. Design efforts were started at Daimler, Bussing, NAG, Benz, Opel. New vehicle received the designation A7V.
On January, 20 Ministry of War requested 100 chassis to be buiit. It was intended to armopr only 10 of them. The project was complete on January, 22. And in April 1917 first chassis has undergone mobility demonstrations, and was shown on 19th of June to Kaiser Wllhelm II.
First tractor based on A7V was sent to the army in September 1917 for trials, and In November (e.g. a month before the first British massive tank attack at Cambre) the first tank was finished.
To be continued.
The Worst US Tank Of World War II
Which was the worst US Army tank of World War II ? If we limit this contest to those tanks which actually went into series production and were deployed with US troops, the nod wouid probably go to the T-16 Sight tank. Most readers may very well not even recognize the T-16, It's service in the US Army was so short and ignominious, that it hardly figures in most histories of US tank development during the Second World War.
Uniike nearly all US Army tanks of World War II, the Marmon Herrington T-16 light tank was not developed on the basis of a US Army requirement. It was a private venture by the company, intended for commercial export. Marmon Herrington was far better known at the time for its commercial trucks. In the 1930s, it had begun to design light tanks for export, including the CTVL for Mexico. The later CTL-3 was purchased by the US Marine Corps for trials. These were not true tanks, lacking a turret, but more like a large tankette. The improved CTL-3M, aiso built for the US Marine Corps, helped form the technical basis for theJater T-16.
A mortar alternative?
Battalion-level artillery was born during the WWI as Infantry support artillery intended for suppression of open and concealed machine-guns that come aiive in the depth of opponent's defense and destroy advancing infantry with their close range fire. The appearance of a tank and the advent of armored forces made battalion-level artillery necessary also for the protaction of infantry from enemy tanks and armored cars.
While battalion AT guns were lately often mentioned in the literature in the recent years, the history of indirect-fire battalion guns was ignored. Of particular interest are the 30s USSR's efforts to create a 76mm battalion howitzer. The Sidorenko's 35K and Grabin's F-23 artillery systems were created. These guns were perfected for a long time, but were never fielded. To a large extent this was due to their apparent competition with mortars. Even though they couldn't replace, only complement, the mortars, as is demonstrated by German and Japanese experience, the mortar proponents in Artillery Directorate opposed everything that could conceivably compete with their favorite. As a result before WWII battalion howitzers were never fielded with the Red Army

New German tank Tiger B (from the Soviet WWII archives)
In August 1944 on the right bank of Vistula river the forces of the Red Army captured new German tanks "Tiger B", produced by MAN plant. According to prisoners' reports, new German heavy tank Tiger B" is caiied "King Tiger" in the German army, However in the User's Manual this term is not used...
This article was published in the "Tank industry bulletin N10/1944. The article quotes the results of the first trials of the tank Tiger Ausf B in Kubinka
