Hi Aichi E7A! Competitor of Kawasaki E7K(Type 94 reconnaissance sea plane).

In early 1932, the Japanese Imperial fleet it has become apparent that the program for replacing high endo spy Type 14 E1Y2 fiasco. The combined efforts represented companies Aichi, Каваниши and Nakajima, under the patronage of state arsenal fleet in Йокосуке not promised imminent success. Work in this direction was the 1928 to 1931 year, and as a result gave gore a mouse. Which emerged as a result high altitude Type 90-3 E5Y1 is not seen its predecessor. Therefore, fleet was forced to order a company Aichi modified version hi spy type 14, adopted by the forces under the symbol E1Y3. Such temporary induced measure, however, has not met relevance issue. Given the failure of the "brainstorming" of several companies, the technical division headquarters aviation fleet Kаigun Kоku Hоmbu took the decision to hold a contest of projects.
I have to say, that a similar situation has arisen in many other projects marine aircraft different classes, therefore, the decision on the design marine aircraft on a competitive basis was virtually all future projects marine aviation until 1945.
Such contests have received the designation "Shisаku Seizо" √ verbatim, "proof-of-industrial production", abbreviated as "leading shipbuilder" with the addition a numeric prefix, the development, from the beginning of the era of planting - the reign of emperor distrust, which came to the throne in 1926. The first trial competition for projects 6-leading shipbuilder was held in 1931. It included only three draft √ night number boat, where braces summoned over bombers and a bench where braces bombers. All three of the draft and have experienced, and in the next, 1932, Kаigun Kоku Hоmbu developed a technical job contest 7-leading shipbuilder, one of the most extensive and ambitious programs in the Japanese history of new cadets. According to the plans fleet in this contest job entered the deck fighter aircraft, torpedoes and summoned over bombers, where braces heavy hammer aircraft, basic bombers, as well as high endo spy.
In the last part of the project period moving averages was granted firms Каваниши and Aichi, since both of those things at the company's refineries slipped long-haul previous-generation E1Y2 and 3 and sufficiently well-familiar with the narrow places of the new E5Y/E5K.
I have to say that the guide firms Aichi озадачилось this problem even before the announcement contest. The year before, in 1931, in Germany in the firm would be Хеинкель
