Dual purpose ships in the service of the Allies killed two birds with one stone. With great ingenuity merchantmen had been provided with flight decks so that they acted as escort carriers while continuing to function as grain vessels, this picture shows one being loaded up at a Canadian port with 7.000 tons of grain, through openings in the flight deck. This ship was only 380 feet long, but Swordfish torpedo bombers of the Fleet Air Arm could take-off and touch down on it with ease.
