To back up what PU151 stated -
Air Force One is most typically a Boeing VC
-25 (which is a heavily modified 742). For airfields that can't handle the VC
-25, one of the C-32s is used.
Air Force Two is most typically a Boeing C-32 (a modified 752)
Marine One is most typically a Sikorsky VH
-3D, a Sikorsky VH
-53D, or a Sikorsky VH
To the best of my knowledge, "Army One" has not been used, and "Navy One" only used once - when Bush flew on an S-3B Viking
to the USS Abraham Lincoln
South Carolina - too small to be its own country, too big to be a mental asylum.
