The E-1 Tracer was the first purpose built airborne early warning aircraft used by the United States Navy. It was a derivative of the C-1 Trader and first entered service in 1958. It was replaced by the more modern E-2 Hawkeye in the early 1970s.

Design and development

The E-1 was designated WF under the old US Navy system; the designation earned it the nickname "Willy Fudd". Since the S-2 Tracker was known as S2F under the old system, that airplane was nicknamed "Stoof"; the WF/E-1 with its distinctive radome gained the nickname "Stoof with a Roof."


The Tracer was fitted with the Hazeltine AN/APS-82 in its radome. The radar featured an Airborne Moving Target Indicator (AMTI), which analyzes the Doppler shift in reflected radar energy to distinguish a flying aircraft against the clutter produced by wave action at the ocean's surface. Separating a moving object from stationary background is accomplished by suitable hardware.
