WVR
Within Visual Range
Within Visual Range describes air combat conducted at close distances where pilots can see the opposing aircraft, relying on short-range missiles, guns, and aircraft maneuverability.
Within Visual Range (WVR) combat, commonly called dogfighting, occurs at distances where the opposing pilots can visually acquire each other, typically within 10 nautical miles. WVR engagements rely on short-range infrared-guided missiles like the AIM-9X Sidewinder, high off-boresight targeting through helmet-mounted cueing systems, and in some cases the aircraft's cannon for close-in kills.
Modern WVR combat has been transformed by helmet-mounted cueing systems and high off-boresight missiles. The pilot can simply look at the target, even behind the wing line, and the missile seeker will lock on, enabling shots that would have been impossible with previous-generation weapons. The AIM-9X, combined with the Joint Helmet Mounted Cueing System, gives even fourth-generation fighters a devastating WVR capability that makes close-range combat extremely lethal for both sides.
The relevance of WVR combat in future wars is debated. BVR-optimized fifth-generation fighters like the F-22 and F-35 are designed to detect and destroy adversaries long before visual range, making WVR engagements theoretically avoidable. However, restrictive rules of engagement that require visual identification, the possibility of BVR missiles being defeated by countermeasures, and the chaotic nature of multi-aircraft engagements mean that WVR combat remains a possibility that every fighter pilot must train for.
