It is launched by a gunpowder booster charge, giving it an initial speed of 115 m/s (380 ft/s), and creating a cloud of light grey-blue smoke that can give away the position of the shooter. [8] The rocket motor [ b ] ignites after 10 m (33 ft) and sustains flight out to 500 m (1,600 ft) at a maximum velocity of 295 m/s (970 ft/s).
