Kawanishi E13K1 Experimental 12-Shi Three-seat Reconnaissance Seaplane

The Kawanishi E13K1 Experimental 12-Shi Three-seat Reconnaissance Seaplane was an unsuccessful attempt to design an aircraft to replace the Navy Type 94 Reconnaissance Seaplane E7K.

In 1937 the Japanese Navy asked Aichi and Kawanishi to produce three-seat long-range reconnaissance aircraft capable of being launched from a catapult but also of operating from shore bases. Kawanishi responded with a low-wing twin-float monoplane of all metal construction apart from the fabric covered control surfaces. The crew of three sat in tandem in a covered cockpit with a greenhouse style canopy that sloped down towards the rear.

The first prototype made its maiden flight on 28 September 1938 and went to the Navy in October for tests against the Aichi E13A1. The Aichi aircraft was faster, easier to maintain and handle on deck, while the Kawanishi aircraft was more manoeuvrable and had a better rate of climb. The maintenance and deck handling problems counted against the Kawanishi design, and the Aichi E13A1 was accepted for production.

Both of the Kawanishi prototypes suffered from accidents. On the first prototype this was triggered by excessive vibration in flight. The second prototype disappeared during a test flight and was never recovered.
