Defenses against aircraft and cruise missiles are a logical adjunct to
defenses against ballistic missiles. Developed technologies could sup
port air defenses complementary to limited missile defenses that would
be effective against reduced threats. While effective missile defense
s should shift emphasis back to aircraft and cruise missiles, technolo
gies in development should be appropriate for projected threats. Inter
national development could improve the performance of defenses and les
sen the risks and consequences of errors.
