Identified by its twin-float biplane configuration, unequal-span wings with the upper wing noticeably larger, and the prominent radial engine; wing-tip stabilising floats are a useful identification feature.

History

Developed in the late 1920s, the E4N entered IJN service around 1931 and was used extensively aboard capital ships and cruisers during Japan's operations in China. It was gradually replaced by more capable monoplanes through the mid-1930s.

Variants

The E4N1 and E4N2 were the primary variants, with the E4N2 featuring a more powerful engine and revised float arrangement.

Where you'll see it

Operated from IJN cruisers and battleships throughout the early 1930s; phased out as monoplane floatplanes became available.
