Why didn't you turn it into your Me 262 then?
Even the Brits hat their Meteor ready by the end of war.
Silly question though, by 1943 you knew you would win the war with conventional means and a Liberty ship was more important to the war effort than a jet fighter (with most likly very limited range making it largely useless to protect the bombers), the nuclear bomb more of a military statement than any jet fighter could have ever been. Just like a Sherman tank was good enough against a Tiger or Panther if there were enough Shermans around and a P-47 or P-51 could beat an Me 262 if there was one around when the Me 262 had to start or land or was parked, and there was basically always one around! What the US learned in WW II was that mechanics of scale are more decisive than advanced state of the art or even novelty arms - it's probably where the still current rule of thumb came from that an attack force needs to be ten times the size of a defense force to ensure victory and not too crippling own losses.
