V3 Mimoyecques WW2 Bunker

The V3 was built in 1943-1944 by Hitler to try to reverse the impending defeat of Nazis... It consisted in barrages of small rocket projectiles fired from 25 underground cannons capable of reaching London ...

The complex was supposed to launch waves of 300 rockets an hour, speeding at 1500 m/second. Each cannon had a calibre of 150mm and was 130m long, lying in underground tunnels. Had these cannons existed, they would have been the biggest guns in the whole world.

Thousands of prisoners were camped in horrible conditions at the complex near Marquise village, to dig the tunnels.

As the V3 represented a big threat, it was massively bombed and finally destroyed on 6th of July 1944, with the powerful "Tallboy" bomb, specially developed to pierce the thick concrete of V-weapon bases.
