Proposed upgrade to all existing F-2s in service of the JASDF, which included the introduction of CFTs, F110-GE-132 EIPE engine, AIM-120, AIM-9X, JHMCS, GBU-31 / 32 and a lot more. Unfortunately never became a thing.
Of course we have to start with the maximum battleship series where we see a real design study for an 80k ton battleship sporting 24 16"/50cal guns in 4 sextuple turrets. Of course the package comes complete with 18" of belt armor and 90k hp driving it up to a maximum of 25 kts… all in 1916
Next we have the United States class carrier. This one was a post war carrier project (that got worryingly far along) for a massive supercarrier. The idea here was to have a ship from which to launch heavy bombers
Last we have a proposed anti aircraft conversion for the Iowa class that armed it with 3 quadruple turrets housing the autoloaded 8"/55 found on the des moines class and a huge 5" and 3" dual purpose secondary battery
I’m seeing a strange pattern of successful American planes getting Swedenized.
Anyways, here’s the mendeleev tank, it’s a highly advanced WW1 concept proposed by the son of Dimitri Mendeleev.
Its front plate is 150mm, its side and rear are 100mm.
It bears the 120mm canet gun and a light machine gun (looks to be a maxim gun)
Top speed is 15 mph (24 kph) with 1.44 hp/t
Crew of 8
It would have pneumatic suspension, the tracks and machine gun turret would both be retractable.
as the wikipedia states:
Mendeleev’s idea of allowing the tank to completely lower the hull onto the ground, turning the tank into a mobile fortress that could bunker down when need be
The initial design is thought to date back to as early as 1898. It was worked upon in 1911, and presented in 1916.
A proposal to upgrade their aging M41s (and possible m42 hulls) to a more modern standard. It incorporated an Abrams turret interior skeleton with a 105mm Gun. Project was canceled due to the fact this turret made the M41 more vulnerable than the original vehicle.
Just a reference
The Avro was one of the first interceptor/fighter that is canadian made and one of the fastest for its time, the project was cancelled because the US doesnt want Canada to have the first, so they demand Canada to dismantle it and hired all of the person that worked on the CF-105
But in short, its quite fast, has good manuverability at high speed, carries weapon on the belly bay which include air to air missle, 1000lb bombs, and guided missle. The missles were all under development(hasnt finished) but ultimately was switch and cancelled because of the US
pretty sad
