The V3 was a multi-chamber super gun, whereby a fin-stabilised projectile was accelerated along a very long barrel by a series of sympathetic detonations of charges located in a herring-bone arrangement. I don't believe that any shots were fired in anger as the V3 facility in Mimoyecques in Calais was bombed into oblivion (during which drone B17s were flown into the complex - and Joe Kennedy (JFK's elder brother) was killed). The RAF finished it off with Tall Boys. I visited it years ago on an Air Power Staff Ride. Thousands of slave workers died as a result of the bombing as an aquifer burst and the tunnels were flooded.My dad was blown off his bike in Cranford Park, Hayes, by a V1 blast. He was 14 and delivering for a local butchers. He said he never heard the V1 engine, he just remembers the blast and coming round, his bike some way away from him and cuts & bruises, mainly from flying stones and earth. He said he hated the V1, the V2 was feared less as it wasn’t such a psychological weapon, you didn’t know it was coming and it was very much an attitude of, I won’t know much about it! The V1 was very much a slow moving, sight & sound weapon that was feared because it was watched, then the engine cut and it was a sense of, On shit, where’s it going to come down!
On a separate note, has anyone got any info on the supposed V3, I believe this was two stage, used liquid oxygen and could hit New York from central Germany?
ETA: apparently Luxembourg was shelled by one.
