The Aichi E11A (九八夜偵, Kyū-hachi Yatei) was an Imperial Japanese Navy flying boat used during the first year of World War II for maritime patrol duties.
It was designed to be launched from cruisers or battleships in order to spot their shellfire at night.
The Type 98s were soon diverted to communications and transport duties.
