HSTV-L

Visual Appearance & Layout

• Ultra-Low Profile: The most striking feature of the vehicle is its highly compressed, low-slung silhouette designed to make it an incredibly difficult target to spot and hit.

• Sharply Sloped Armor: The hull front features an aggressive, wedges-like frontal slope designed to maximize the effective line-of-sight thickness of its aluminum-alloy armor and deflect incoming kinetic rounds.

• Cleft Turret: Unlike conventional main battle tanks, it uses a highly unconventional cleft or low-profile turret where the main gun sits in a central split, significantly minimizing the exposed surface area above the hull ring.

Armament & Firepower

• Main Gun: The tank is armed with the 75mm Ares XM274 automatic cannon. It fires specialized Cased Telescoped Ammunition (CTA) where the projectile is fully enclosed inside the propellant casing.

• Rapid-Fire Autoloader: Supported by an advanced automatic feeding system, it is capable of firing devastating burst sequences with an incredibly fast reload speed of roughly 0.85 to 1.0 seconds between shots.

• Ammunition & Targeting: It carries a 26-round capacity carousel. The primary kinetic shell is the XM885 APFSDS (Armor-Piercing Fin-Stabilized Discarding-Sabot), paired with the XM884 HE-VT proximity-fused shells for engaging low-flying helicopters and anti-aircraft threats.

• Extreme Elevation: As clearly highlighted in the photo, the main gun possesses a massive range of motion, providing a remarkable vertical guidance angle from -17° of gun depression up to +45° of elevation.

• Secondary Weapons: It features a coaxial 7.62mm M240 machine gun, alongside a second commander-operated 7.62mm machine gun located near the top sight housing.

Technical Specifications & Measurements

• Weight: 20.45 metric tons (roughly 22.5 US tons).

• Hull Length: 5.918 meters.

• Total Length (Gun Forward): 8.528 meters.

• Width: 2.794 meters.

• Height (Overall): 2.414 meters.

• Height (To Hull Roof): Just 1.422 meters.

• Ground Clearance: 0.508 meters.

• Powerplant: Powered by an Avco-Lycoming 650 horsepower gas turbine engine paired with an X-300 transmission.

• Mobility: Yields a high power-to-weight ratio of roughly 31.8 hp/ton, enabling a blistering top road speed of 83.6 km/h (52 mph) and an operational cruising range of 160 kilometers

It's a cutie inside though

It's a High Survivability Test Vehicle – Lightweight, so no face no normal human body

Rather empty base
