This project was quite a surprise to me! Three things strikes me particularily about it:
1. the minuscule size; it's smaller than most WW2 escort carriers were!
2. the icebreaker bow, which must be unique for a carrier design and gives us clues about the planned areas of deployment.
3. the unmistakable de Havilland Vampire which the carrier seems to be designed around (lift size, hangar dimensions, etc.) which is remarkable since the drawing is dated less than six months after the first flight ever by a Vampire from a carrier (incidentally also the first jet to fly from a carrier!) and almost two and a half year BEFORE the first flight of a production Sea Vampire!
