40x46mm Round RLV-TB Thermobaric Grenade


The RLV-TB round is intended for combined destruction, both by air-blast and thermal emission: of the enemy manpower and equipment located mainly in different types shelters and covered areas, and in the open, as well as of light armoured and unarmoured vehicles.

The 40x46 mm Round RLV-TB consist of Thermobaric Grenade with AF41 fuze and Propellant charge CP-42. At a safe distance 10m, after the grenade has left the barrel, the fuze gets armed. Upon meeting a target, 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 composition is generated which detonates from the bursting charge. A zone characterized with over pressure and temperature is created in the area.

The round is designed for use with 40x46 mm Underbarrel Grenade Launcher UBGL-M6 and its modifications, as well as M203; HK 69; etc.

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.
