Engineering Brief - Experimental Demonstrator
Military Tank Conversion for 90-Degree Vertical Fire
Full technical analysis covering angle-dependent torque, hydraulic actuator sizing, manual transmission strategy, costs, and real-world feasibility.
Important preamble
No operational main battle tank is designed to fire at 90 degrees. Modern MBTs (Leopard 2, M1 Abrams, T-90, etc.) are typically limited to about +20 to +42 degrees. A 90-degree concept is an experimental demonstrator, not a standard military retrofit.

Tactical advantages of vertical fire
Additional operational capabilities
How a cannon reaching 90 degrees of elevation creates new battlefield options.
Anti-air defense
Potential engagement of low-altitude threats (helicopters, diving aircraft, loitering munitions) where a standard tank is constrained by elevation limits.
Helicopters · Aircraft · DronesDrone neutralization
FPV threats and steep top-attack vectors can be addressed with direct fire when turret elevation is sufficient.
Modern C-UAS threatUrban combat
Ability to engage elevated positions (roofs, upper floors, terraces) without major repositioning to recover usable elevation.
Urban overmatchMountain warfare
Direct engagement of high-angle targets with fewer detours and reduced operational delay.
Reduced blind angleIndirect mortar-like fire
At very high elevation, near-vertical terminal trajectories could reach targets behind cover and fortifications.
120 mm mortar-like effectExpanded versatility
A single vehicle can combine conventional direct fire with anti-air and indirect options, reducing reliance on specialized assets.
