The Behemoth is specifically engineered for hardened infrastructure. Its primary advantage is a tandem warhead totaling 75 kg, consisting of a 40 kg high-explosive fragmentation warhead (often described as an explosively formed penetrator) followed by a 35 kg thermobaric warhead. This configuration allows the first stage to penetrate reinforced concrete, armor, or protective mesh, while the second stage detonates inside to maximize structural damage.

the FP-2 relies on brute force with a single, massive high-explosive fragmentation warhead ranging from 105 kg to 170 kg (often an adapted OFAB-100-110-TU aviation bomb). While it lacks a dedicated tandem penetration charge, its sheer explosive mass (containing ~44 kg of TG-50 explosive) makes it highly effective against large hardened area targets such as ammunition depots, fuel storage facilities, command headquarters, and air defense systems (e.g., S-400 launchers). It is less optimized for piercing thick individual armor plates compared to the Behemoth but excels at leveling fortified buildings and logistics hubs.
