Navy's Pocket Carrier Beats U-Boat Packs - A Swordfish going down the lift of one of Britain's latest escort carriers. A second aircraft in charge of its crew is waiting. Note the extreme narrowness of the bridge, from which the ship is controlled on the right-hand side of the deck. Aboard one of the Navy's latest "pocket" escort carriers, which are proving such an effective counter weapon to the U-Boat pack. October 25, 1943. (Photo by British Official Photograph).
