From here, EMALS and other Ford-class problems, "Naval Air: 2USS Truman Gets Dent":

Quote: "...EMALS less reliable than the older steam catapult. EMALS was also more labor intensive to operate and put more stress on launched aircraft than expected. Worse, due to a basic design flaw, if one EMALS catapult becomes inoperable, the other three catapults could not be used in the meantime as was the case with steam catapults. This meant that the older practice of taking one or more steam catapults offline for maintenance or repairs while at sea was not practical. The navy admitted that in combat if one or more catapults were rendered unusable, they remained that way until it was possible to shut down all four catapults for repairs. During the initial at-sea tests the EMALS failed once every 75 aircraft launches. The standard for steam catapults is one failure every 4,166 launches. The landing and recovery system also had reliability problems, failing once every 76 landings, which is far below the standard of one failure per 16,500 landings. In effect, these problems with launching and recovering aircraft make the Fords much less effective than the older Truman and other Nimitz class CVNs"

 

Oh dear that is very sad reading.
