History

Type 0 Recon Seaplane, also called Type 0 3-Seat Recon Seaplane is a Japanese naval recon plane developed by Aichi Clock before WW2.

Development of this plane started in request of 1937. In this project Kawanishi and Aichi joined. Aichi design No.12 Experimental 3-Seat Recon Seaplane but they missed the delivery data (September 1938) so Aichi was disqualified because they advanced in 3 projects (Prototype No.11 Special Recon Seaplane "AB-14, E11A", No.11 Experimental carrier-based dive bomber "AM-17, D3A" and No.12 Experimental 2-seat recon seaplane "AM-19") but they continue development.

Main designer was Matsuo Kishiro, and Assistant designer were Mori Morishige and Ozawa Yasuo. Company name was "AM-18, E12A". They based No.12 Experimental 2-Seat Recon Seaplane (AM-18) and first prototype completed in Janualy 1, 1939 and start test flight.

On the other hand, Kawanishi delivery to the navy No.12 Experimental 3-Seat Recon Seaplane and test flight started. Its on-water stability is not good so second prototype modify floats. But in parallel Aichi doing test flights and it specification was not a bad so disqualification was canceled and competition started.

Cruise range of Kawanishi's one is superior to Aichi's one, but Max speed of Aichi's one is superior to Kawanishi's one. But during test flight 2nd prototype of Kawasaki's one was missing. Because of this incident examination of Kawanishi's one was discontinuation so Aichi's one was adopted.

 

This plane produced by Aichi clock (aircraft section independent in 1943 as Aichi aircraft) and Watanabe ironworks (aircraft section independent in 1943 as Kyushu aircraft).

Variation of this plane is below:

• E13A1 / Type 0 Recon Seaplane Model 11 --- Initial model. At first it called Type 0 Mark 1 Recon Seaplane Model 1.
• E13A1a / Type 0 Recon Seaplane Model 11 Ko: Modify float from 2 pillar to 4 pillar per one float. Add spinner. Some plane equip Type 3 Air Mark 6 Radar to search vessels.
• E13A1b / Type 0 Recon Seaplane Model 11 Otsu: Add Type 3 Mark 1 Detector for ASW.

Also there are several variations.

• PT-boat hunter, equip 20 mm single machine gun on rear
• Night recon plane, equip long exhaust pipe to hide fire
• Auxiliary torpedo bomber for battle of Japan
• Kamikaze attacker

In game they have very strange color... I don't know why.

Open for discussion.

This would be a fun tier 1 plane.  +1.

[Miki_Hoshii 2,449]

Definately competitive enough for War Thunder. Would love to see this +1

Apparently in 301st Recon and 302st Recon of 634th Navy Air Group, E13A equipped torpedoes for preparation of battle of Japan!

Also, some E13A modified to equip Mk27 rocket bomb.

I support more float planes for Japan+1

[Tetravault 225]

+1 Gib more floats

[Z3r0_ 4,128]

The one with the rear cannon could be hilarious

Now that it is available as ship-launched model, should be so easy to add to normal tech tree.
