Minor quibble:  the extended tailpipes don't do a lot to suppress IR
emissions, as it is pretty hard to do much about a jet engine's IR,
especially against modern heat-seekers (which home on the exhaust, not
the hot engine parts).  The extended tailpipes come from experience
with shoulder-launched-SAM hits:  those simple little missiles tend
to hit in the tailpipe area, and they don't have a very big warhead,
so if the tailpipe is nice and long, all they do is dent the sheet
metal.
