Looking for naval fighters on the web I found this article with pictures of Republic P-47 Thunderbolts embarked on aircraft carriers. There was a naval version of this plane? The report and photos, never seen by me before, can be viewed at the link below:
P-47s were sometimes transported to their operational areas by aircraft carrier, as were Spitfires and Hurricanes for Malta etc. They could fly off, but not land back on as they had no arrester gear. they weren't naval variants. The aircraft in your photos are certainly being delivered somewhere, but its hard to tell whether it was Italy / North Africa or the Pacific. The fully wrapped aircraft are probably en route to England (Liverpool most likely) where they would be unloaded by crane, as it was too difficult to remove the wrapping at sea, and they had port infrastructure available to unload.
If it was supposed to be easy. everyone would be doing it...
If you watch the Great Planes documentary episode on the P-47 (available on youtube), there is a good ten minutes of footage of 'naval' P-47s (starts approx 27 min in). The P-47s were loaded on to 'jeep' carriers at Pearl Harbor, then flown off to the newly reconstructed airfield at Saipan during the Marianas campaign in 1944.
