Dealing with a pocket battleship threat but with a twist. Instead of one of the great powers assume you have a nation that cannot build its own capital ships, that has to deal with a pair of pocket battleships around 1932. Say for example Goeben proved unrepairable and its guns were used for a...

There is already a thread on what might have been in the 1930s. I want to focus on the land forces. Britain and France in 1940 had some tanks (Somua and Matilda 2) which could match the Germans. If the French and British General Staffs had understood the importance of armoured units in a...

An interesting midget submarine that became a vital part of an even more interesting operation of the Decima Flottiglia MAS that came close to fruition in 1943 (it was ultimately scheduled for December of that year, but events intervened). Development of the CA-class had begun pre-war, in 1938...

Hi, in 1938,Parnall designed a twin boom heavy bomber Project,with no supporting tailplane or structure between the booms,how we can find a drawing or a more Info about it ?.

A handful of examples of the Saro/Blackburn Segrave twin-engined light touring monoplane were built in the early 1930s, mainly by Blackburn at Brough. Some were license-built by Piaggio as the P.12, but I don't know how many (Wikipedia suggests just two). The last Blackburn-built Segrave was...

New book available which may be of tangential interest to SPF members. Automotive history is filled with concepts which never left the drawing board, with early streamlined projects being among the more fascinating. This book presents ten of the most striking and unusual aerodynamic automobile...

Enrico Cernuschi and Vincent O'Hara's article on Italian aircraft carrier design ("Search for a Flattop: The Italian Navy and the Aircraft Carrier 1907-2007") in Warship 2007 has a passing mention of two mid-1930s proposals for carrier-based aircraft: the Caproni Ca.165 biplane fighter and a...
