When the attacks began in mid-June of 1944 there were fewer than 30
Tempests in 150 Wing to defend against them. Few other aircraft had the low-altitude speed to be effective. Early attempts to intercept V-1s often failed but techniques were rapidly developed. These included the hair-raising method of using the airflow over an interceptor's wing to raise one wing of the Doodlebug, by sliding the wingtip under the V-1's wing and bringing it to within six inches (15 cm) of the lower surface. Done properly, the airflow would tip the V-1's wing up, overriding the buzz bomb's gyros and sending it into an out of control dive.
At least three V-1s were destroyed this way. The Tempest wing was built up to over 100 aircraft by September;
P-51 Mustangs and
Griffon-engined
Spitfire XIVs were polished and tuned to make them almost fast enough, and during the short summer nights the Tempests shared defensive duty with
Mosquitoes. Specially modified
P-47Ms (half their fuel tanks, half their 0.5in {12.7 mm} machine guns, all external fittings, and all their armour plate removed) were also pressed into service against the V-1 menace....
In daylight, V-1 chases were chaotic and often unsuccessful until a special defence zone between London and the coast was declared in which only the fastest fighters were permitted. Between June and mid-August 1944, the handful of Tempests shot down 638 flying bombs...
Next most successful was the Mosquito (428), Spitfire XIV (303), and Mustang, (232). All other types combined added 158. The still-experimental jet-powered
Gloster Meteor, which was rushed half-ready into service to fight the V-1s, had ample speed but suffered from a readily-jammed cannon and accounted for only 13.
By mid-August 1944, the threat was all but overcome—not by aircraft but by the sudden arrival of two enormously effective electronic aids for anti-aircraft guns, both developed in the USA by the
MIT Rad Lab: radar-based automatic gunlaying...and the
proximity fuse. [emphasis added]
