The number of different ships you need depends on how many of the ship lock restricted-entry maps (E-4, E-5) you want to clear on medium or hard...if you want to do both of those maps on medium for example, you would need 6 ships for E-3, 12 different ships for E-4, and another 6 different ships for E-5 (so yes, 24 for full ship locking).

We can't be sure about the possibility of support expedition ship locking yet, since this behavior was variable in past events...though I personally think that support expedition ships will be excluded from the ship locking mess.
