Warships that never were – the Soviet ‘Sovetsky Soyuz’ class battleship (I)

The ‘Sovetsky Soyuz’ class comprised four battleships which were started in the late 1930s but not completed. Designed in response to the battleships being built by Germany, the class was to have totalled 16 ships, but in the event only four had been laid down by 1940, it was decided to curtail the programme to …

The secondary armament of the ‘Montana’ class battleships was planned as 20 5-in (127-mm) L/54 guns in 10 turrets located as five on each side of the ships’ central superstructure ‘island’.

Warships that never were – the US ‘Montana’ class battleship (I)

The ‘Montana’ class of battleships planned by the United States Navy were schemed as successors to the ‘Iowa’ class ships, but reverted to a more traditional concept inasmuch as they were slower but larger, better armoured and more heavily armed.

Fighters which did not make the cut – the Lockheed F-90

With its P-80 Shooting Star firmly established in production during 1945, in July of that year Lockheed was able to commit its development team to the start of work on a more advanced fighter. The first step in this process was the creation of a number of conceptual designs, and these eventually totalled more than …

Fighters which did not make the cut: The Republic F-91 ‘Thunderceptor’

Bearing a close conceptual and structural resemblance with the P-84 (later F-84) Thunderjet series in its fuselage and the F-84F Thunderstreak in its swept tail unit, Republic’s design for a ‘penetration fighter’ received an initial US Army Air Forces order in March 1946 for two XP-91 prototypes which emerged only after the USAAF had become …
