#OTD – 23 March 1918 – The Paris Gun
A Centenary Action

On this day in 1918, in support of Operation Michael, the massive “Pariskanone” (Paris Gun) fires on the French capital for the first time. Weighing over 600 tons and with a barrel measuring approximately 36 metres long, it could fire a 230-pound shell approximately 130 kilometres. The first shells that struck Paris were fired from approximately 120 kilometres away – a range so great that the Coriolis Effect (the rotation of the Earth) had to be factored into aiming the weapon.
