The E-1B (WF-2), an airborne early-warning aircraft, is from a large family which also included the S-2 Tracker, C-1 Trader and others. It carried a crew of 4 and could operate from any Navy aircraft carrier. The large dish houses long-range search radar to detect targets beyond the line-of-sight of surface vessels. This aircraft was the last E-1B to leave Navy service.
