Offensive counter air

Air warfare conducted to actively destroy enemy aircraft and ability to wage aerial warfare

Offensive counter-air (OCA) is a military term for the suppression of an enemy's military air power, primarily through ground attacks targeting enemy air bases: disabling or destroying parked aircraft, runways, fuel facilities, hangars, air traffic control facilities and other aviation infrastructure. Ground munitions like bombs are typically less expensive than more sophisticated air-to-air munitions, and a single ground munition can destroy or disable multiple aircraft in a very short time whereas aircraft already flying must typically be shot down one at a time. Enemy aircraft already flying also represent an imminent threat as they can usually fire back, and therefore destroying them before they can take off minimizes the risk to friendly aircraft.
