Using the V2 is a poor example, as that was a combined effort with both the British and the Americans. While Operation Crossbow it did achieve some of its goal, I can't find documentation that it was the RAF sorties that achieved damage to the V2 and its related infrastructure. I'm not terribly well versed in the history of the V2 during WWII, so I may just be missing it. The best thing the Brits did was use double-agents to send the Germans misinformation about where they were striking. They gradually convinced the Germans that the rockets were landing on the far side of London harmlessly. The physics behind the V2 at the time clearly placed it as striking London, but the misinformation essentially demanded changes in the engineering. London was still hit plenty though, so this intelligence campaign was not a total success. If this had actually been totally successful, the Brits might as well have helped Germany setup more V2 factories. Each V2 was extremely costly in terms of materials to produce. This removed available materials from the parts of the war effort that actually needed them.
