The carrier based E-1B Tracer provided critical early warning and guidance support. Its four man crew was able to remain in flight up to seven hours. The most distinguishing feature of the E-1B is the enormous aerodynamic radome over the truck of the aircraft.

With the delivery of the E-­‐1B Tracer, Grumman delivered to the Navy an aircraft with a single purpose; airborne early warning. Entering service in 1954, the E-­1B was a derivative of the still relatively new S-­‐2 Tracker. But the Tracer was distinct in its appearance because of its top mounted radome, a strong but electronically transparent thin shell that housed radar equipment.
