Douglas Havoc

“Havoc” was the RAF name for the night-fighter and intruder versions of the American Douglas DB-7 / A-20 design, the day-bomber version of which the RAF called the Boston. Painted black and fitted with airborne interception radar and a heavy nose battery of guns, Havocs flew home-defence night patrols and intruder sorties over German-occupied airfields from 1941. Some were converted to the unusual “Turbinlite” role, carrying a powerful nose searchlight to illuminate enemy bombers for an accompanying single-seat fighter — an idea that proved largely impractical.
