improve living conditions for the crew, and enhance ease of supervision and maintenance. Each room was separated from adjacent spaces by double watertight bulkheads, which increased structural strength and reduced the possibility of a single torpedo hit disabling two engine rooms at a time. The system as a whole was capable of generating , and Aquila was expected to reach on trials and when fully laden. At a displacement of 27,800 tons, maximum fuel supply was 2,800 tons, and operational range 4,150 nmi at 18 kn and 1,210 nmi at 29 kn. With maximum fuel load, 3,660 tons, Aquila would displace 28,800 tons, with a range of 5,500 nmi at 18 kn and 1,580 nmi at 29 kn. Hangar Aquila had a hangar with a total length of , a width of , and height of . This space was divided into four sections by five fire doors, section length from fore to aft being 32, 25, 25, and 35 meters. Hangar floor capacity was 26 aircraft for the Re.2001 OR Serie II, with seven in the 32-35 meter sections and six in the 25 meter sections. Additionally, fifteen aircraft could be suspended from the hangar ceiling. A planned folding-wing version of the aircraft was to have allowed the stowage of sixty-six aircraft in the hangar. Flight deck Aquila had a single continuous flight deck. It was partially armored with plate over the gasoline bunkers and magazines. The flight deck ended short of the bows but overhung the stern, where it featured a pronounced round-down to improve air flow. Two octagonal lifts with a capacity enabled transfer of aircraft between the hangar deck and flight deck. One was directly amidships and the second another forward, thus placing them far enough from the aft arrester wires that both could be used for striking down aircraft into the hangar immediately after a landing. Two German-supplied Demag compressed air-driven catapults, each capable of launching one aircraft every 30 seconds, were installed parallel to each other at the forward end of the flight deck. These were originally intended for Germany's own "Carrier B", Graf Zeppelin′s incomplete—and eventually scrapped—sister ship. The Italians obtained them—along with five sets of arrester gear and other component plans—during a naval technical mission to Germany in October–November 1941. A set of rails led aft from the catapults to the elevators and into the hangars. For catapult-assisted launches, aircraft would be
