A carrier raid on Kiel could reshape the Atlantic war

What if Britain had launched a mass carrier raid on Kiel in 1939?

A four-carrier night strike could devastate the German surface ships there and might push Germany toward completing Graf Zeppelin instead.

In this explicitly counterfactual scenario, Britain concentrates Ark Royal, Courageous, Glorious, and possibly Furious for a night attack on Kiel. The estimate is roughly 144 Swordfish and sixty Skuas, divided into two waves. Scharnhorst, Gneisenau, and Admiral Scheer would face massed torpedo and bombing attacks while Germany still lacked an effective night-fighter defense. The operational risk to four carriers would be considerable, but destroying the available German surface force could justify it in light of the later Atlantic campaign. A successful raid might also shift blame toward the Luftwaffe and redirect German effort from repairing surface ships into completing Graf Zeppelin. Following that chain links one carrier decision to later fleet allocation, procurement, and the possibility of an Atlantic carrier battle.
