Northrop Grumman E-1 Tracer
Photo Tracer, New England Air Museum, 2001
First flight 17 December 1956
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 Grumman
C-1 Trader and first entered service in 1958. It was replaced by the more
modern E-2 Hawkeye in the early 1970s.
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 aircraft was nicknamed "Stoof"; the
WF/E-1 with its distinctive radome gained the nickname "Stoof with a
Roof." The E-1 featured folding wings for compact storage aboard
aircraft carriers. Unlike the S-2 and C-1 in which the wings folded
upwards, the radome atop the fuselage necessitated the E-1 to fold its
wings along the sides of the fuselage.
