he USAF has put stealth aircraft in harm's way without jamming. Jamming
would be counterproductive, as it would indicate an attack is imminent.

Really? During Balkan conflict no US aircraft,stealth or not,flew without
Jammer support.
Two f117 were hit ,one lost,the other safely returned,both because of jammer
failures.

The originator of now famous saying "Jammers are like American Express never
leave home without them" is a f117 "driver".period.
