The KAPLAN Anti-Tank Vehicle (STA) is the smallest member of the KAPLAN new-generation armored combat vehicle family developed by FNSS. The vehicle is powered by a diesel engine coupled to a fully automatic transmission system that provides a 21 hp/ton power-to-weight ratio allowing joint operation capability with main battle tanks. It has a maximum road speed of 65 km/h, with a cruising range of over 525 km.  The KAPLAN STA is 5.6m long, 3m wide, and has an overall height of 3.1m. Its advanced torsion bar suspension system is specifically designed to minimize vibrations in the vehicle and improve road handling. The vehicle has a low silhouette, and with its twin tracks (five road wheels each side), it can operate at high speeds, not only on asphalt but also on soft soil or muddy and rough terrains under all weather conditions. The KAPLAN STA can climb a gradient of 70% and a side slope of 40%. It can cross a vertical step of 0.75m and a trench of 1.8m.

The vehicle has a modular platform design that allows it to execute a wide variety of missions by integrating different subsystems. It is equipped with an advanced self-protection suite consisting of a CBRN Protection System, A/C, Automatic Fire Extinguisher, Mine Resistant Seats, and Smoke Grenade Launchers. It has two self-sealing fuel tanks at the rear that are fully armored and isolated from the vehicle to ensure the safety of personnel.

The KAPLAN STA is one of the very few vehicles in its class that has fully amphibious characteristics with water speeds up to 6.3 km/h. Its hull is water-resistant, and both the hatches and lids are water-proofed via seals. The vehicle can enter the water without any prior preparation, and thanks to its two rear-mounted propulsion systems, it can move in deep and fast-flowing streams.

The hull of the KAPLAN STA is manufactured using a unique welding technique that provides advanced ballistic protection. The vehicle features mine and blast resistance and offers high mobility under different geographical conditions thanks to its lightweight hull. The power pack and the expanded driver cabin are located at the front of the vehicle, while the gunner and the commander sit in the middle of the vehicle. The rear section of the vehicle is allocated for the assistant gunner and additional crew members.  The KAPLAN STA can be accessed through the integral personnel door on the ramp or the hydraulic ramp located at the rear of the vehicle. The power pack can be removed through the cabin access hatch for maintenance and repair.
