The S&T Daewoo K11 DAW (Dual-barrel Air-burst Weapon) is an assault rifle chambered to fire 5.56x45mm NATO rounds, as well as 20x30mm air-burst smart grenade from its overbarrel launcher. Two conventional 20 mm shells either detonate immediately on impact or on a timed fuse after impact. A third type of shell is controlled by the weapon's integrated electronics to explode a few meters from the target, yielding an air burst effect capable of killing targets within a 6 m area and seriously wounding those within a 8 m area. Users enter a range at which the shell is to detonate, allowing targets in ditches, in buildings, or behind walls to be destroyed without requiring the shell to strike the target.
