Paint Scheme Notes
F-111As had a different camouflage pattern than all the other tactical variants.
This is most evident around the nose. They initially had white undersides, but
this was changed to olive drab on the Harvest Reaper F-111As. By the time of
the Constant Guard V deployment to Thailand in 1972 the undersides were black,
a color used until the overall gray scheme was adopted by tactical F-111s in the
early 1990s. F-111s were the last aircraft to use the Vietnam era colors, with
Desert Storm aircraft using this scheme because most aircrew found it much easier
to fly tactical formation with.
US-based F-111A and F-111Ds had hard-edged patterns, virtually identical between
aircraft, while European-based F-111Es and F-111Fs had soft edged patterns,
which were generally similar from one aircraft to the next.
FB-111As were painted in a unique scheme using SAC colors.
Aircraft 68-0250 was painted in a new ‘European One’ scheme
in early May 1984, with all other FB-111As being repainted in due course.
