Jet aircraft on straight-deck carriers

Did the US Navy have difficulty operating jet aircraft from straight-deck carriers?

Not fundamentally; straight decks operated jets successfully, while angled decks solved landing-speed, safety, and sortie-rate problems.

Straight-deck carriers operated jet aircraft before angled flight decks became standard. Angled decks addressed problems associated with higher landing speeds and the way carriers organized launches and recoveries. Those changes also affected sortie rate. During the Korean War, straight-deck carriers operated jets or piston aircraft according to their air groups, without needing an angled deck to make flight operations possible.
