An electrically powered mobile fort
The Aubriot-Gabet Cuirassé was an experimental French effort to move protected firepower using electrical power supplied from outside the vehicle. The clearest evidence assembled in the cited sources is a photograph of the wheeled armored machine in November 1915. A cable linked it to its power supply, making it fundamentally different from a tank carrying an engine and fuel for independent movement. Sources
The combined Aubriot-Gabet name is retained as the available evidence identity. The official photographic description emphasizes Gabet, while the account discusses differing accounts of Aubriot’s role. That is a subject for attribution research, not a reason to rename the original assignment silently. Sources
The reported tracked, petrol-electric follow-on was a separate development. The available evidence does not establish its construction securely enough to present two completed vehicles. Gabet's smaller remotely controlled land-torpedo work was not a crewed tank variant despite its use of electrical systems. Sources
Development in the mobile-fortress tradition
The concept belongs to French experiments in protected mobile firepower during the early war. Rather than begin with a mature tank layout, it treated the protected gun position itself as something that could be moved toward a military problem. Accounts place Gabet’s earlier electrical and remote-control interests in this background, while keeping those interests distinct from the photographed armored vehicle. Sources
The chronology brings together reports of earlier experiments, wartime proposals, and the November 1915 image. The photograph provides a firm visual anchor, but it does not, by itself, establish every stage of design or testing. A reported December follow-on remain unconfirmed rather than being accepted as the next photographed configuration. Sources
The relationship to a particular commercial chassis is unresolved in the assembled research. Filtz and Caterpillar/Holt associations appear in the source discussion, but the cited evidence does not justify assigning a manufacturer with the certainty appropriate to an identified procurement record. That uncertainty remains unresolved in any technical summary. Sources
Electric drive and gun installation
The photographed vehicle carried an armored upper structure on wheels and depended on a trailing electrical cable. Accounts describe an electric motor, but does not establish its output, a complete transmission specification, or the exact generating arrangement. It is therefore possible to explain the operating concept without inventing a horsepower figure or self-contained engine installation. Sources
A small gun, generally identified in the available evidence as 37 mm, formed the intended protected firepower. Its exact model, ammunition allowance, mounting details, and traverse remain uncertain. The presence of an upper gun structure cannot establish a claim of fully rotating turret performance without supporting evidence. Sources
Two crew are reported, but their exact stations and duties are not securely established. Hull dimensions, armor thickness, range, and sustained speed are similarly incomplete. These gaps are not appropriately filled with figures quoted for the later petrol-electric proposal. Sources
Testing, limitations, and the follow-on proposal
The external supply cable placed a basic constraint on how the vehicle could move. It tied the experiment to infrastructure outside the armored body and introduced a vulnerable connection across the ground. Published accounts describe this dependence as a central weakness of the concept; it does not supply a complete official trial report measuring the vehicle’s behavior in battle conditions. Sources
The reported petrol-electric and tracked follow-on would have addressed a different propulsion arrangement. Its existence as a described project is not the same as demonstrated construction, acceptance, or service. A responsible family overview can explain the proposed change while keeping the build status unresolved. Sources
The references identify no serial-production program or combat service. The photographed wheeled vehicle supports a prototype-level account. The cited accounts do not firmly establish exact totals beyond that evidence. There is also no established operator fleet to populate from the broad institutional labels in the available accounts. Sources
Related electrical experiments are not tank variants
Gabet’s land-torpedo experiments help explain why electrical control and propulsion recur in the wider story. They nevertheless address a different kind of device from a crewed armored mobile fort. Their inclusion as contextual technology cannot increase the number of tanks in the encyclopedia. Sources
They may show a proposed arrangement clearly, but they cannot resolve whether a historical follow-on was built, how its hull was dimensioned, or which chassis was used. The photographed prototype, contemporary project descriptions, and later interpretations remains separate evidence categories. Sources
This treatment makes the overview useful without manufacturing a more elaborate production family than the sources support. Sources
Photographic evidence and remaining questions
The published embedded image is particularly valuable because it shows the cable-fed wheeled machine rather than a generic later tank. The proposed caption identifies the vehicle, the November 1915 context, and the ECPAD collection attribution. Sources
One useful archival view is better than a larger gallery padded with unrelated electrical machines. A lack of additional photographs in the cited record is not evidence that no such material exists anywhere. Sources
The most important historical questions remain the precise chassis, the construction status of the follow-on, gun identification, crew arrangement, protection, and the respective roles of the named contributors. The project’s interest lies in the attempt to combine protection and electrical mobility, not in a falsely complete specification sheet. Sources
