The was the first purpose built airborne early warning aircraft used by the
United States Navy . It was a derivative of the
S-2 Tracker and first entered service in
1954 . It was replaced by the more modern
E-2 Hawkeye in early
1970s .
The E-1 was designated 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 thus inherited the nickname "Stoof with a Roof."
