S&T Daewoo K11
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.
In May 2010, the United Arab Emirates purchased a quantity of 40 K11s for evaluation purposes for a total cost of US$560,000, giving an indicative unit cost of US$14,000.
