Studies of air combat in the Vietnam War inevitably focus on the MiG-killing fighter engagements, B-52 onslaughts or tactical strikes on the Hanoi region. However, underlying all these was the secretive -electron war- in which highly-skilled electronic warfare officers duelled with Soviet and North Vietnamese radar operators in the attempt to enable US strike forces to reach their targets with minimal losses. Orbiting at the edge of heavily-defended territory, the vulnerable EB-66s identified and jammed the enemy-s radar frequencies with electronic emissions and chaff to protect the American bombers. Their hazardous missions resulted in six combat losses, four of them to SA-2 missiles and one to a MiG-21, and they became prime targets for North Vietnamese defences when their importance was realised. This illustrated study focuses on the oft-overlooked B-66 series, examining their vital contributions to the Vietnam War and the bravery of those who operated them in some of the most chall
