A beyond-visual-range missile is an air-to-air missile that is capable of engaging at ranges around 40 km (22 nmi) or beyond. This range has been achieved using dual pulse rocket motors or booster rocket motor and ramjet sustainer motor. Medium-range, long-range, and very-long-range air-to-air missiles fall under the category of beyond-visual-range missiles. Older BVR missiles generally used the semi-active radar homing, and modern BVR missiles use the active radar homing guidance.
In addition to the range capability, the missile must also be capable of tracking its target at this range or of acquiring the target in flight. Systems in which a mid-course correction is transmitted to the missile have been used.
