On 17/18 August 1943, Harris ordered Operation "Hydra", a series of attacks against the Peenemünde Army Research Center producing V-weapons. Raht scrambled to intercept but only caught one Lancaster with his radar operator east of Flensburg at 02:57. Raht spotted the bomber caught in searchlights and fired off an identification flare to force the anti-aircraft batteries to cease-fire against the bomber. Raht swiftly dispatched the bomber, identified as "ED725" PM-P. It belonged to No. 103 Squadron RAF and P. J. O'Donnell and his crew were killed. On 23/24 August Raht claimed his 12th victory southeast of Thomsdorf at 00:58. Raht did not score a victory again until 27/28 September 1943, when he accounted for a Lancaster over Hanover. The report lists Raht as belonging to 4./NJG 3 at this time. Raht claimed his 14th victory northeast of Stendal. The report described the enemy aircraft as a four engine bomber but did not specify the type. The 15th claim was filed that same night, when he reported a Lancaster shot down over Haguenau.
