Hello,

You can find a photo of the E9W: HERE

You may click on it to enlarge the image.

If indeed this binocular was used by a submarine borne aircraft, it has to be rather rare.

Keep safe,
Arthur Pinewood :hi:

I think that it is the Watanabe E9W Japanese submarine-borne reconnaissance seaplane in orange colour.
Designed by Watanabe ironworks.

It is a biplane with radial engine.

Silly question: was this aircraft launched from the submarine via the torpedo tubes? Just joking, except, how did they launch it? Presumably they had a hatch and lift big enough for the fuselage with floats attached and then mounted the wings when it was floating, and recovery was the same procedure in reverse. However they did it the sub and plane must have been vulnerable for a fair length of time.

It says it took 2.5 minutes to assemble and 1.5 minutes to disassemble or vice versa.
Some of the aircraft were launched by catapult and then recovered when it landed on the floats.
A biplane might only need 50 knots to stay airborne. If the wind was 10 knots, only 40 knots is needed to launch.

Other countries including Britain had similar aircraft but didn't pursue them.

The Navigation officer may actually be what we called the Observer, who would use the binocular to identify shipping.

The biplane is bright orange all over and the registration number covers almost the whole of the top wing to prevent attack by Zeros.
At 10,000ft one can see 125 miles.
The ceiling was over 20,000ft presumably on oxygen.
The aircraft was slow, but all the observer needed was height.
