Watanabe E9W

The Watanabe E9W was a Japanese submarine-borne reconnaissance seaplane, the first aircraft designed by Watanabe Ironworks.

The aircraft entered service in 1938 with the Imperial Japanese Navy Air Service as the Navy Type 96 Small Reconnaissance Seaplane with the last being delivered in 1940.

Although it was in the process of being replaced by the Yokosuka E14Y monoplane, it was still in front line service at the time of the Japanese attack on Pearl Harbor, remaining in service until July 1942, being used to direct their parent submarines onto Chinese ships attempting to pass the Japanese blockade of the South China Sea.
