Four in the cockpit, the rest at the consoles

The E-3's crew is split into two groups. The flight crew consists of four people: aircraft commander, pilot, navigator and flight engineer. Added to them is a mission crew of 13 to 19 specialists. That second group is not fixed, because its size varies depending on the mission to be flown. A different count gives a total crew of 17 to 25 people, with a mission crew of between 13 and 21.

Eight hours in the air

The E-3 can fly a mission profile of more than eight hours without in-flight refueling. USAF and NATO E-3s have an unrefueled range of more than 5,000 nmi (9,300 km). Versions fitted with CFM56 engines reach about 11 hours.

What the radar watches

The pulse-Doppler radar reaches more than 250 mi (400 km) against low-flying targets, at the aircraft's operating altitude, and the pulse radar (BTH) reaches about 400 mi (650 km) against aircraft at medium and high altitudes. E-3 production ended in 1992, after 68 aircraft were built.
