The introduction of AEW & CS platforms into the subcontinent by the Pakistan Air Force (seven Saab 2000s of the Kamra-based No.3 Sqn and four CETC of China-supplied ZDK-03 Karakoram Eagle KE-3s of the Masroor-based No.4 Sqn) in the previous decade, and followed by the Indian Air Force’s (IAF) procurement of three A-50I PHALCONs from Israel and three locally-developed EMB-145Is earlier this decade) has seen aircrew of both air forces act like air-traffic controllers for military aircraft on operations. Due to this, the AEW & CS platforms have become as proficient in an offensive role as in a defensive role. In the former, the aircrew on board the AEW & CS platforms can now guide both combat and combat-support aircraft on to targets during offensive engagements, be they on land, in the air or at sea. While doing this, the platforms still maintain their defensive roles by informing friendly pilots what other aircraft are within their area of operations, be they friend or foe. The A-50I, for instance, can detect low-flying targets within a diameter of 400km or 215nm. At medium-altitude, it can detect targets within 520km or 280nm. Thus, one A-50I cruising at 9,150 metres (30,000 feet) has a radar coverage of 312,000 square kilometres. It is capable of controlling six airborne interceptions and managing three tactical strike missions at the same time, an EMB-145I can control three interceptions and manage one tactical strike mission at the same time) airborne near Pathankot at the same time.
