I am interested in Steam Gun Boat, a British WW2 design for a relatively large, well armed ship which was intended to be used mostly in coastal waters and was to be easily mass produced in non-military shipyards. However, it has proven to be to complex, and they were forced to produce them in shipyards that produced various military vessels, thus defeating its reason for existance.

It was relatively fast and well armed for a vessel of its size, in its final configuration it had speed of 30 knots, and was armed with 1x76mm, 2x57mm, 2x20mm and 2x533 torpedoes.

Now, I am interested to know, how would these craft fare in conditions of WW1. They were relatively short ranged, but rather seaworthy as well, so how would they perform and compare to other small craft in various areas, from North Sea, Belgian Coast and Mediterranean.

Also, how would they be used by both sides, by Entante and Central Powers, presuming they can build them.
