A: EMALS uses an electromagnetic "rail gun" to launch/arrest aircraft. After delays of between five and twenty years (depending on how you look at the schedule) it''s closer to becoming a reality, and is installed on the carrier Gerald R. Ford (CVN 78) which was "commissioned" in 2017 but will not be operational until sometime between ...

Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. However, there are a number of drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients
