40x46 mm Round RLV-TB with Thermobaric Grenade

Manufacturer

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, caves and in the open, as well as 
- of light armoured and unarmoured vehicles.
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 rounds are designed to be fired from:
- Underbarrel Grenade Launchers: ARSENAL UBGL-M8, UBGL-M7, UBGL-M16; M203; HK 69; etc.;
- Stand-alone Grenade Launchers: ARSENAL UGGL-M1, HK 69A1; M 79; STAR FN SCAR; M320; etc.;
