A single-engined [[biplane]] that was designed and developed by the [[Yokosuka Naval Air Technical Arsenal]] as a reconnaissance aircraft for the [[Imperial Japanese Navy]], 320 were built as the '''Type 14 Reconnaissance Seaplane''', entering service in 1925 and remained in operational service until 1932.

==Development and design==
==Development and design==
In 1921, the Japanese Naval Arsenal at [[Yokosuka, Kanagawa|Yokosuka]] started design of a single-engined reconnaissance [[floatplane]] to replace the Navy's [[Yokosuka Ro-Go Ko-Gata]] floatplanes. The resulting aircraft, the '''Type 10 Reconnaissance Seaplane'''{{ref label|Note1|a|a}} was designed by a team lead by a member of a visiting delegation from [[Short Brothers]] of the [[United Kingdom]]. It was a single engined two-bay, two-seat [[biplane]] powered by a 400&nbsp;hp (298&nbsp;kW) [[Lorraine-Dietrich]] engine. Two were completed in 1923, but showed poor performance due to being overweight. A modified aircraft, the Type 10 Model A flew in 1924, showing only slight improvement, while a further revised prototype, the Model B flew in 1925, this curing the aircraft's weight problems while demonstrating better stability and control. As a result, several pre-production Type Bs were built.<ref name="Mikesh p272"> Mikesh and Abe 1990, p.272.</ref>

Two versions entered service in 1926, a two-seater powered by a 400&nbsp;hp Lorraine Deitrich 1 V-12 engine, the Type 14-1 or E1Y1, and a three-seater with all-metal floats and a more powerful Lorraine-Deitrich 2 [[W engine]].<ref name="Mikesh p274"/> In 1928, the Type 14-2 was used as the basis for the Type 90-3 Reconnaissance Seaplane, of which about 20 were built as the [[Yokosuka E5Y1]] and [[Kawanishi E5K1]].<ref name="Mikesh p278-9"> Mikesh and Abe 1990, pp.278—279.</ref>

As the Type 90-3 showed little improvement over the Type 14-2 from which it was developed, in 1931, Yokosuka developed the further refined Type 14-3 Reconnaissance aircraft, with a new tail, a geared Lorraine-Deitrich 3 engine and significantly improved performance.<ref name="Mikesh p274"/>

The E1Ys formed the main reconnaissance seaplane equipment of the fleet, operating from [[Battleship]]s and [[seaplane tender]]s. E1Ys were operated from the seaplane tender [[Japanese seaplane carrier Notoro|''Notoro'']] during the [[January 28 Incident|Shanghai Incident]] of early 1932.

Role Reconnaissance floatplane
National origin Japan
Manufacturer Yokosuka
First flight 1923
Introduction 1926
Primary user Imperial Japanese Navy
Number built 320[1]

The Yokosuka E1Y was a Japanese floatplane of the 1920s. A single-engined biplane that was designed and developed by the Yokosuka Naval Air Technical Arsenal as a reconnaissance aircraft for the Imperial Japanese Navy, 320 were built as the Type 14 Reconnaissance Seaplane, entering service in 1925 and remained in operational service until 1932.

Development and design[edit]

In 1921, the Japanese Naval Arsenal at Yokosuka started design of a single-engined reconnaissance floatplane to replace the Navy's Yokosuka Ro-go Ko-gata floatplanes. The resulting aircraft, the Type 10 Reconnaissance Seaplane[a] was designed by a team led by a member of a visiting delegation from Short Brothers of the United Kingdom. It was a single-engined two-bay, two-seat biplane powered by a 400 hp (298 kW) Lorraine-Dietrich engine. Two were completed in 1923, but showed poor performance due to being overweight. A modified aircraft, the Type 10 Model A flew in 1924, showing only slight improvement, while a further revised prototype, the Model B flew in 1925, this curing the aircraft's weight problems while demonstrating better stability and control. As a result, several pre-production Type Bs were built.[2]

Although the Type 10 was not adopted by the Japanese Navy,[2] it was again redesigned, reducing the wingspan from 16.16 m (53 ft 0¼ in) to 13.99 m (45 ft 11 in) and reducing the empty weight from 1,912 kg (4,215 lb) to 1,660 kg (3,659 lb).[3] In this form, the revised design was accepted in January 1926 as the Type 14 Reconnaissance Seaplane, later receiving the short designation E1Y.[4]

Two versions entered service in 1926, a two-seater powered by a 400 hp (300 kW) Lorraine-Dietrich 1 V-12 engine, the Type 14-1 or E1Y1, and a three-seater with all-metal floats and a more powerful Lorraine-Dietrich 2 W engine.[5] In 1928, the Type 14-2 was used as the basis for the Type 90-3 Reconnaissance Seaplane, of which about 20 were built as the Yokosuka E5Y1 and Kawanishi E5K1.[6]

As the Type 90-3 showed little improvement over the Type 14-2 from which it was developed, in 1931, Yokosuka developed the further refined Type 14-3 Reconnaissance aircraft, with a new tail, a geared Lorraine-Dietrich 3 engine and significantly improved performance.[5]

A total of 218 E1Y1 and E1Y2s were built by Yokosuka (23), Nakajima Aircraft Company (47) and Aichi (148). 102 E1Y3s were built by Aichi.[7]

Operational history[edit]

The E1Y1 and E1Y2 entered service in 1926, replacing Yokosuka Ro-Go Ko-Gata and Hansa-Brandenburg W.33 seaplanes, with the E1Y3 following them into service from 1931. The E1Ys formed the main reconnaissance seaplane equipment of the fleet, operating from battleships and seaplane tenders. E1Ys were operated from the seaplane tender Notoro during the Shanghai Incident of early 1932. The E1Y remained in use until the early part of the Second Sino-Japanese War.[5]

Many E1Ys were sold as civil aircraft from 1932, usually converted with a cabin for three or four passengers. Some were fitted with Napier Lion engines.[8]
