== Fate == One of the two Lampaden guns was dismantled on 15 February 1945, and firing ceased on 22 February, when US Army units had advanced to within 3 kilometres (1.9 mi) of the Lampaden site. A second battery of guns began to be deployed in January 1945 at Buhl, aimed at Belfort in support of the Operation Nordwind offensive. One gun was erected before the failure of the Nordwind offensive put the site at risk, and the equipment was removed before firing could begin. There were other proposals to deploy batteries to bombard London, Paris, Antwerp and other cities, but they were not implemented due to the poor state of the German railway network and a lack of ammunition. All four HDP guns were eventually abandoned at the Röchling works in Wetzlar and Artillerie Abteilung 705 was re-equipped with conventional artillery. The disassembled gun tubes, spare parts, and remaining ammunition were later captured by the US Army and shipped to the United States where they were tested and evaluated at the Aberdeen Proving Ground, Maryland, and scrapped there in 1948.
== Museum == The Mimoyecques museum provides public access to the underground galleries, which exhibit varying degrees of structural completion and historical bombardment damage. The site’s holdings include the remains of the original ordnance, a small-scale replica of the V-3 weapon system and authentic examples of the machinery, rail infrastructure, and tools utilized during the facility's operation. The site also contains memorials to the slave labourers who were forced by the Nazis to construct it and to the airmen killed in action during the destruction of the base. The Misdroy site also has a museum.
== Scale model == Hugh Hunt of Cambridge University, together with explosives engineer Charlie Adcock, created a working scale model of the V-3 gun and was able to prove the ignition of the propellants was done by the advancing gas behind the projectile.
