Weighing nearly 17 tons on paper, Vasily Mendeleev’s proposed Tanks project in 1911 stands as one of the most ambitious conceptual blueprints in early armored warfare history. Long before tanks crawled across the trenches of the Somme, a Russian naval engineer envisioned a heavily fortified, land-battleship that combined battleship-grade armor with internal combustion propulsion. Yet, the sheer scale of the vehicle's mass created insurmountable engineering bottlenecks that kept the machine permanently rooted on the drafting board.
Understanding the Mendeleev tank weight requires looking beyond simple tonnage statistics and examining the interplay between early propulsion limits, heavy artillery plating, and structural feasibility. While popular retellings often gloss over the mechanics, the reality of designing a 17-ton armored vehicle in the pre-World War I era revealed severe gaps in industrial manufacturing, suspension technology, and engine output.
The Origins of Vasily Mendeleev’s Armored Concept
Vasily Mendeleev, son of the famous chemist Dmitry Mendeleev, began working on his design in 1911 while serving as an engineer at the Kronstadt naval yard. Drawing heavily from his naval background, Mendeleev approached land vehicle design the way shipwrights approached cruisers. He incorporated thick steel plating, compartmentalized internal spaces, and a heavy naval gun turret integrated directly into the chassis.
The initial blueprints called for a vehicle measuring approximately 10 meters in length, protected by boxy steel armor ranging from 100 mm to 150 mm on the front, and 100 mm on the sides and rear. To put this into perspective, most World War I tanks built years later carried a fraction of that thickness. This massive structural ambition directly dictated the vehicle's projected weight, pushing calculations to roughly 14.5 to 17.3 tons depending on the fuel and ammunition loadout.
Breaking Down the Projected Mass
The primary driver behind the high tonnage was the sheer thickness of the proposed box hull. Mendeleev refused to compromise on crew survivability, specifying steel plates that could withstand direct hits from contemporary field artillery.
- Hull Armor: The thick steel plates accounted for nearly half of the total vehicle mass, creating a protective box that sheltered a small crew and a pneumatic lifting system.
- Internal Armament: A retractable 75mm naval gun was housed in the front hull, backed by a pneumatic mechanism designed to lower or raise the weapon depending on combat needs.
- Propulsion System: A single gasoline engine producing around 100 horsepower was selected to drive the heavy chassis, which presented an immediate power-to-weight deficit.
- Track Integration: Uniquely, Mendeleev designed an internal rail system that allowed the entire hull to be lowered directly onto its tracks or raised onto hidden railway wheels for long-distance transport via standard train tracks.
This pneumatic lifting gear and internal track-lowering machinery added considerable mechanical complexity and dead weight to the interior, severely restricting space for the crew and fuel storage.
The Fatal Flaw: Power-to-Weight Deficit
The core reason the Mendeleev project never progressed past blueprints was a fundamental mismatch between mass and mechanical power. A 17-ton vehicle driven by a 100-horsepower engine yielded a dismal power-to-weight ratio of less than 6 horsepower per ton.
For comparison, successful early tanks like the British Mark I operated with similarly tight margins, but Mendeleev's heavy concentration of weight over rigid, unarticulated tracks meant the vehicle would have likely bogged down immediately in soft mud or trench terrain. Without a flexible track system wrapping around the entire hull—a breakthrough later popularized by British and French engineers—a heavy box-like chassis acted like a sledge rather than a tractor.
Furthermore, Russian heavy industry in the early 1910s lacked the specialized facilities required to mass-produce reliable, high-output internal combustion engines capable of moving such heavy loads across rough terrain. The Imperial Russian Army's Main Artillery Directorate ultimately rejected the proposal, citing prohibitive production costs, excessive weight, and logistical nightmares in transporting such a heavy vehicle to the front lines.
How It Compares to Early Operational Tanks
To truly understand why the design's mass was problematic, look at how contemporaries tackled weight management during the First World War:
- British Mark I (1916): Weighed roughly 28 tons, but distributed that weight across a massive rhomboid track footprint that spanned obstacles and trenches effectively.
- French Renault FT (1917): Weighed a mere 6.5 tons, prioritizing agility, a rotating turret, and a small footprint that revolutionized modern tank doctrine.
- Mendeleev Project (1911): Sat at 17 tons on rigid tracks with no over-the-tracks suspension, creating a high ground-pressure profile that would have stalled on standard European soil.
Mendeleev’s project was ahead of its time conceptually, but it suffered from an acute misunderstanding of how ground pressure and weight distribution dictate mobility on unimproved terrain.
Frequently Asked Questions
Did the Mendeleev tank ever see combat?
No. The vehicle was never built as a physical prototype. It remained strictly a private design concept submitted to the Russian Main Artillery Directorate in 1912, where it was subsequently rejected.
Why did Mendeleev include railway wheels inside the hull?
Because early Russian roads were notoriously poor and rail networks were the primary method for moving heavy equipment across vast distances. The internal pneumatic jacks allowed the tank to lift itself off its tracks and ride directly on civilian or military train tracks.
How thick was the proposed armor?
Mendeleev specified armor up to 100 mm to 150 mm on critical frontal arcs, which offered protection far exceeding anything deployed on actual battlefield tanks for the next two decades.
Who funded the development of the design?
Vasily Mendeleev funded and drafted the project entirely on his own initiative as a personal engineering study, without direct commission or financial backing from the Russian military.
