ww2dbaseThe Sea Otter flying boats were developed from the Walrus design, with the most significant difference setting the two apart being the orientation of the engines -- the engines were mounted in a forward-facing fashion with Sea Otter aircraft, as opposed to rear-facing with Walrus aircraft. 592 were originally ordered to be manufactured, but the end of WW2 meant only 292 was built between 1942 and 1945. Most of them were employed by the British Royal Air Force, British Royal Navy, and the Royal Australian Navy, while eight of them were sold of the Royal Danish Air Force, eight to the Danish Naval Air Arm, and six to France for use in French Indo-China.
