The Iwo Jima (CV-46) of the Essex class was cancelled incomplete after the war. But according to Friedman, there were plans to redesign the ship to alleviate the deficiencies of the Essex class (the plans died with the cancellation of the carrier): Does anyone have information on this redesign?

Is the water-alcohol injection R-2800 on the P-47s, so they can make 2300-2600-2800 HP instead of 2000-2100 HP, also cheating? Engineer in ww2: we've managed to make our engines do extra 15-20-30% HP more, with reasonable reliability. 21st century enthusiast: cheater! Three things: - there...

I didn't see any topics featuring or referencing this interesting airship (including the compelling figures involved in its development and construction), but I came across a some newsreel footage of it worthy of posting and created this topic for reference and as a potentially clearinghouse for...

Since the end of the First World War, bold attempts were made in the Soviet Union in the field of rockets and various types of weapons, although timid, but existing and somewhat significant for the hard period that the Union was going through at that time, sometimes typically handcrafted and...

Grigorii Ivanovich Bakshayev was interested in the concept of variable geometry aircraft, where the size and/or shape of wings are altered according to the stage of flight, or desired characteristics. There are many methods of achieving this but one of the simplest is the telescopic wing, where...

From the third volume of the US Navy's 'Springstyle' plan books is one of the designs the US Navy looked at during the design process that led to the Midway Class Carriers. The design work was actually completed after the 'Scheme B' design which will be the feature of a future post. This one...

The Royal Navy's second 16" armed battleships history was a long and bumpy road of large number of designs and the inability on the Admiralty's side to actually start and continue it's work on them or choose a design to produce. First I present the 1938 designs: Design 14A-38 This is the first...
