This is a small "Super Lion" design
My smallest Super Lion design in the early 1970's was for a 750ft-long ship with a 100ft beam. I did another version which was practically Vanguard size. My actual Springsharp design has a greater displacement and I added 4in QF guns to have 16, as that is a more reasonable anti-torpedo boat armament than only 12-4in QF. I went with a uniform 7in belt between the end barbettes. The ends are 4in, as I could not justify going with "All or nothing" for the Super Lion. The design has a "Tiger" look, with three equally spaced funnels and a tripod foremast. This is the Springsharp report:
