Landship

The British Landship Committee formed during World War I to develop armored vehicles for use in trench warfare.

The British proposed building "landships," super-heavy tanks capable of crossing the trench systems of the Western Front.

However, even at a revised weight, 300 tons was considered impractical given the technology present, but the influence of the big wheel would persist in the "creeping grip" tracks of the first tanks, which were wrapped around the entire body of the machine.

It was the largest caliber rifled weapon ever used in combat and, in terms of overall weight, the heaviest mobile artillery piece ever built.

Super-heavy tanks such as the British TOG 2 and the Soviet T-42 were built in a similar layout as naval battleships, albeit on a smaller scale.

[7] Extremely large hovercraft such as the Zubr-class LCAC used by both the Russian Navy and the PLAN could also technically cover some aspect of landship design by factor of it being also capable of traversing overland as a partial-terrestrial vehicle.

At over 50 meters long with a max tonnage weight of 555 tons, it is the closest one could get to a modern military landcraft, although it is more of an amphibious hovership than anything else.

They were exceptionally tall, had multiple decks, staircases and ladders, and some were armed internally with emplaced weapons such as ballistas, catapults or onagers and cannons.

Currently, the only country utilizing armoured trains in the modern era is Russia, where it is used more akin to a land-base landing ship on rails as of December 2023.

As their role involves the collection of vast underground resources in large bulk, their physical dimensions dramatically increased to accommodate the transferral of those materials and easily dwarf any other ground vehicles by several orders of magnitude.

The Overburden Conveyor Bridge F60 is considered the largest vehicle in physical dimensions of any type and has been referred to as a "lying Eiffel Tower.

[15] Spreaders are incredibly large ground vehicles that are meant to 'spread' overburden into a neat, consistent and orderly manner.

[16] Stackers are mining vehicles that exclusively run on rails and are imposing in size, with some stacker-reclaimer hybrids having a boom length of 25 to 60 meters.

Reclaimers, as its name implies, 'reclaim' bulk material such as ores and cereals from a stockpile dumped by a stacker and are quite large, with bucket-wheel types usually having a boom length of 25 to 60 meters.

Large underground vehicles designed to drill and create subterranean subway transits, some of which weigh about 5,000 tons.
