The 1948 RN Cruiser Projects

[Tzoli]

Soon after WW2, the Royal Navy sketched up a couple of cruiser designs mostly as theoretical representatives of what the RN would need in the future and whose embodied the new technologies then under development:
- 6inch Mark XXVI Main Battery Weapon (1953)
- Medium Calibre DP Weapon (5"/70) (1957)
- 3/70 for secondary Battery (1953)
- New DA Close Range Weapon (1957)
- LRS.1 Long-Range Director and TS Equipment (1953)
- MRS.3 Director and Predictor (1953)
- MRS.4 Director and Predictor (1957)
- TIU Mk.III (1954)
- Type 960 Radar (Already existing)
- Type 992 Radar (1954)
- Sea Slug Missile (1958)

The first among these sketches were the small, medium and large cruisers of 1948/49 often called as the "1960 Cruiser" because the technologies above would be only ready by 1960.

And here are my drawings of the Sketch I and II designs
I've used the final Type 901 Radar director for the Sea Slug, and a quad 40mm/70 OQF Mark XI gun mount for the DACR which I envisioned as a somewhat smaller sextuple mount as used on Vanguard.
