Alicorn and the vulnerabilities of a submarine carrier

How would you sell the Alicorn submarine aircraft carrier to a real navy?

The pitch would promise carrier power with submarine concealment, but surfacing for flight and railgun operations would expose an isolated vessel with limited sensor height.

Ace Combat's Alicorn is described as a submarine aircraft carrier with two nuclear reactors, a large flight-deck railgun, two secondary railgun turrets, missile launchers, and capacity remembered as about 60 aircraft. The panel corrects its submerged displacement to 810,000 tons and quotes a length of 495 meters, with a crew of 350 sustained for at least two years without resupply. Those fictional capabilities make a tempting sales pitch for carrier power with submarine concealment. The operational criticism is that such a vessel would be too attractive to deploy alone, losing the protection normally provided by a carrier task group. It must spend time on the surface to launch and recover aircraft or fire its main railgun. Escorts ordinarily provide the defensive layers and time a carrier needs to organize its aircraft and respond to attack. Alicorn's low height above water would also restrict sensors and long-range air defense compared with a surface ship of equivalent size.
