Shchitonoska - Based on FT-17?
Permalink Closed


We have learned some information over time about this one-man vehicle. As we all know, it turns out none were ever built. It was a private venture by the engineer Maksimov in 1919.

One wonders, what were Maksimovs inspirations, how did he come up with the idea?

Well, in 1919 Russia was equipped with some British tanks, aswell as some FT-17s. In fact, the Shchitonoska was supposed to use the 4 cylinder Fiat engine then in production, which ended up being used for the KS FT-17 copies. One of the only specific design features we know about Maksimovs design was that it was driven in the prone position, and had 10 small bogie wheels.

Well, the FT-17 has 9 small bogie wheels. Could Maksimov have simply designed a one-man version of the FT-17 by lengthening it a little bit, turning the space in front of the engine normally occupied by a standing gunner and a sitting driver into a space to lay in the prone position for a combination Driver/Gunner, and redesigning the tracks?

We all know that Russia had a hard time building up the infrastructure to manufacture tanks. Their first homemade vehicle was a FT-17 copy in 1920, and only 15 of those were made by 1922. Could Maksimovs design have been about using cheaper materials, a simpler chassis, weaker armor, and building a vehicle that could actually be mass produced in Russia at that time?

I photo-hacked a picture of the Russian KS FT-17 copy into what I think Maksimovs design might have looked like. I used John Milsoms sketch of the vehicle as a template.

And yes, I am bad at making pictures like this, but I think you get the idea.

What do you think?

Perhaps I should have phrased my question better. Obviously there is no way for us to know what was going on in Maksimovs head, or what a vehicle, that was never built and of which no plans exist, would look like.

I was simply wondering if you think my hypothesis was plausible.

Plausible but not the only possibility. There were a number of Russian factories already manufacturing powered track units - as part of various half track vehicles. These could provide a relatively cheap and available source of tracks.

And for such a small vehicle, light-weight would be the name of the game.

The Russians were producing Kegresse style track units domestically correct?

Kegresse track units have rather large bogie wheels, four in each unit. Perhaps it was intended that each Shchitonoska vehicle be equipped with lengthened Kegresse units, consisting of 10 bogie wheels? The manufacturing of such a vehicle would be far easier than my FT-17 idea, as the manufacturing capability was already in place.

I just whipped up this image... If the Shchitonoska vehicle was to use lengthened Kegresse units, then this is what those track units might have looked like. It is worth noting that the bogies are very similar in size, in relationship to the length of the tracks, to Milsoms drawing.


I think your idea is far more likely than mine Centurion.

One thing that has puzzled me though, is do you think the Shchitonoska would have had curved armor as depicted in the sketch? The Vezdekhod had, or was meant to have, curved armor plates. So perhaps the idea of a little one-man kegresse tracked vehicle with fully curving armor isn't such an outlandish idea?

Thin curved armour plate isn't easy to manufacture so for example turrets with a curve at the period tended to be cast (and heavier) plate tended to be angular (however one firm in Britain had solved the problem - they made Admiralty pattern turrets for example). Often a curved plate turret would be thick boiler plate or the like. One wonders if Russian (Soviet) industry at the time was up to curved armour plate.

There were several improvised armored cars of the WWI era with curved armor, but it was always mild steel or boiler plate or the like, never proper armor plate.

At the time Maksimov designed the Shchitonoska, the Russian Civil War had been going on for around 2 years, and would continue on for another 3 years.

Presumably the Shchitonoska would have been used in the infantry support role, never being intended to go "over the top" in trench warfare the way the FT-17 and British tanks were. As such, the vehicles prime advesary would be troops with rifles and machine guns. perhaps Maksimov thought that cheap thick curved mild steel/boiler plate would best suit his vehicle. The vehicles name, "Shield Bearer", is also interesting. Could the vehicle have been intended for soldiers to hide behind, or on one side of it, using it as sort of mobile fortification? Or perhaps that "fin" in Milsoms drawing is actually an infantry shield, similar to the Krupp Light Tank?

The Shchitonoska was to be around 2.25 tons, with 10mm armor, presumably throughout the vehicle. British and American one-man tanks sported armor only from 5 to 9 mm, and in turn weighed around 1.5 tons. The much higher weight and thicker armor of the Shchitonoska could be an indication it was to use thick boiler plate in place of actual hardened armor.
