Robert Lochner (engineer) harbours to Franklin Roosevelt and Winston Churchill. The decision to go ahead was taken and full-scale trials of the floating breakwater started in April 1944. During the trial, an onshore gale produced heavy seas, but Robert's bombardons calmed the waves effectively. Assembling two Mulberry Harbours the day after the landings on 7 June 1944 was one of the most remarkable engineering feats in history. A total of 1,500,000 tons of harbour equipment had to be taken across the channel in an operation involving 150 Allied tugs, and by D-Day 'plus 12', most of Lochner's concrete breakwaters were in position. On
390th Strategic Missile Wing On 25 May 1944, a detachment of the group was directed to bomb coastal defenses in France using radar, despite weather conditions that were ideal for visual bombing. Although crewmembers were not advised why radar bombing was directed, this mission was a test to determine if pathfinder operations would succeed if the weather over Normandy was foul when the invasion took place. Thereafter, the group would frequently use pathfinder techniques when clouds obscured its assigned targets. The group bombed the coast near Caen fifteen minutes before the D-Day landings in Normandy on 6 June 1944. It attacked enemy artillery in
