wiki見る感じダーツそれぞれがレーザー誘導で飛んでるんじゃないの？
The dart housing is made from a tungsten alloy. The darts are each 396 millimetres (15.6 in) long, 22 millimetres (0.87 in) in diameter, and about 900 grams (32 oz) in mass. Around half the weight of each dart – approximately 450 g (16 oz) – is its explosive charge, detonated by a delayed-action, impact-activated fuse.[6] Each dart consists of a rotating fore-body, with two canard fins, attached to a non-rotating rear assembly with four fins. The rear assembly of each dart also houses the guidance electronics including a rearwards facing sensor.
The darts do not home in on laser energy reflected from the target; instead, the aiming unit projects two laser beams which paint a two-dimensional matrix upon the target. The lasers are modulated, and by examining these modulations the sub-munitions sensor can determine the dart's location within the matrix. The dart is then steered to keep it in the centre of the matrix. The sub-munitions steer by briefly decelerating the rotating fore-body with a clutch. The front wings then steer the missile in the appropriate direction. The three sub-munitions fly in a formation about 1.5 metres (4.9 ft) in radius, and have enough kinetic energy to manoeuvre to meet a target evading at 9 g at 7,000 metres (23,000 ft) altitude.[6]
