40mm Round RLV-TBThermobaric Grenade

The Round RLV-TB is intended for: Combined destruction, both by air-blast and thermal emission, of the enemy manpower and equipment located mainly in different types of shelters and covered areas, and also for light armoured and unarmoured vehicles. The 40 mm Round RLV-TB consists of a Thermobaric Grenade with AF41 fuze and Propellant charge CP-41.

The Propellant charge CP-41 serves to transfer the required initial velocity of the grenade and to ensure the stability of its flight. At a safe distance, after the grenade has left the barrel, the fuze gets armed. Upon meeting a barrier, the fuze AF41 gets activated and initiates the bursting charge which, in its turn, disperses the thermobaric composition TBC-2.

The thermobaric composition TBC-2 interacts with the oxygen from the air; an air-fuel mixture is generated which detonates from the bursting charge. A zone characterized with increased pressure and temperature is created in the area.

The round is designed for use with 40 mm Underbarrel Grenade Launcher UBGL-1 and its modifications, as well as Underbarrel Grenade Launchers GP-25, GP-30 and GP-34.

The rounds can be stored in non-heated storerooms for 10 years, but only if they are kept in the original non-opened packing of the manufacturer.
