Gadila-class Merchant Aircraft Carrier

These ships originated in a plan from the Naval Staff in London to equip several ships to a type of carrier that was part of the emergency measures during the war. The Merchant Aircraft Carrier is in fact nothing more than a merchant vessel with a flight deck built over it. During the war, they have proven to be very useful as convoy escorts, providing them with air cover when needed. Originally, it was the plan to convert several passenger ships of the Ruys-class of the KPM. These ships were serving as troop ships, and were to valuable in that role. But these tankers proved to be suited for this task too, and were converted from 1943 to 1944. Both were ready in 1944 and made several voyages over the Atlantic, without ever facing the enemy. Both ships returned to Merchant Service post-war. This class was identical to the British Rapana-class.
