There are only a few production stealth planes, F-22, F-35
and the trusty F-117. Though some may argue F-35 is LO, not
stealth
It is cheaper and easier to get a LO plane like F-15SE or
F-18(?). These planes uses materials at selected places and
CFT to hide stores. It will not be completely invisible but good
enough at long range.
Do you know that the B-2 spends most its time in the
hangar? The maintenance of the joints and panels is an
interesting experience.
