Aichi E13A (Jack) Story

In terms of numbers alone, the E13A series seaplanes (called "Jacks" by the Allies) produced by Aichi were the most important type of aircraft of this type for the Japanese Navy during World War II. The system was widely used in the early 1940s and was responsible for reconnaissance for the U.S. Navy at Pearl Harbor, Hawaii, prior to the infamous December 7 attack.

Designed for outstanding durability and endurance, the E13A served until the end of the war and was notorious for kamikaze attacks on advancing U.S. Navy convoys.

The E13A is a low-flying three-person monoplane equipped with pontoons instead of a conventional landing gear system. The initial demand for seaplanes stemmed from the Japanese Navy's need for a new seaplane to replace the aging Kawanishi E7K2 series. Therefore, proposals were made to Aichi, Kawanishi and Nakajima Aircraft to encourage them to try competition. In the end, only one designed by Aichi and Kawanishi remained, and Aichi Design received the green light.

A prototype was then built and ordered into production after 1940.

Although initially limited in numbers, the E13A family performed some early carrier-based ground attack and reconnaissance missions, encouraging the use of this type of aircraft. Therefore, the seaplane will be regularly used with future cruiser groups and will be installed on the catapults of Japanese battleships.

Standard armament consists of a downward-firing 1 x 20mm cannon and a 7.7mm machine gun in the rear cockpit. External stores are limited to a single 551-pound bomb or depth charge as needed.

Aichi "Jacks" are used more for their scouting initiative than their punching ability (which is limited in this regard). Reconnaissance missions included the Pearl Harbor reconnaissance and the American strike group's famously misrepresented reconnaissance mission early in the Battle of Midway, which had many carrier-based attack aircraft operating on the decks of Japanese carriers, awaiting the arrival of reconnaissance reports.

The Aichi E13A will serve until the end of the war, although every month it is limited by a new generation of carrier-based fighters and the ever-advancing U.S. military. The Jakes, like other aircraft of this type, were later downgraded to carry out kamikaze attacks on American ships, hoping to destroy psyches and disrupt supplies and combat capabilities.

Ultimately, this superb aircraft will be considered the best seaplane Japan can deploy, and 1,418 production models of this type will attest to that.
