New UK Carriers - aircraft launch

[pzu]

Probably missed it elsewhere, but how will the proposed new UK carriers launch their aircraft?

Rely on STOL/VTOL and Ski-jump, or catapult?

If catapult, how will this be powered?

Steam or some newer form of propulsion - MAGLEV or similar?

Initially, the carriers will be configured just for STOVL with a ramp for the new JSF aircraft.

However, the design includes the ability to upgrade the carrier for conventional aircraft launch using a catapult.

This is a requirement of the contract, since the carriers have a designed life expectancy of 50 years, i.e. longer than the service life of the new JSF aircraft.
