Post subject:  Type 18 Frigate Conversion
During the early 1950's the RN was looking at the problem of providing large numbers of ASW ships. The problem was that all WW2 built ASW ships (River, Loch, and even Castle classes) were too small and too slow, to fight the new Russian submarines, those name by NATO Whiskey class. The solution was convertin the large number of WW2 built destroyers of the 'O' to 'Z' classes as frigates, and so HMS Rocket and HMS Relentless were chosed to a full conversion. The result was the Type 15 conversion, which was considered a very successful it was very expensive. Plans were drawn for a cheaper solution, the Type 18

In the end none were ever built, the ships that were meant to be converted to Type 18 were converted to Type 15 at the end.

Nice drawing, but it seems outright strange for a late forties-early fifties destroyer to only have two guns and in the stern no less.
Is the tub just behind the 40mm(?) gun a director?

Useless for a 1948-1950's ASW western ship to carry 4 to 6 large guns (100+mm), because during this era, the main (soviet) threats was attacks by soviet subs, light forces (MTB), mine and aicrafts. (soviets cruisers/destroyers was expected to remain in harbor, due to very large US/UK fleet dominance)

A twin 102mm was clearly sufficient to deal with a surfaced russian sub and a mix 40-102mm battery was well suited againts MTB.
The only major weakness was the inability for the 102mm gun to deal with modern air threats (this mount, designed by early 1930's, was clearly too slow (in speed elevation/movement terms) againt last generation of soviet piston engine aircrafts and early generation of soviet jets aircrafts)

The Type 15/16 conversions were actually carried out and there are a few ships represented already in the database (and while you're at it, they all need to be redone anyway).

I understand why they did it (or considered it anyway) but it just goes against my aesthetics.

It is also on the main site. Type 16 will be done.

Yeah there are still some that need to be redone though, you can see on the database.

I think your refering to 'Unknowns' work, on the Archive (not database) and yes, over time these are being redone, plus other types not yet represented. The Type 18 was never completed as it was in between the Type 15 and 16 in capability and considered too expensive compared to the limited Type 16, but it would have provided a better Type for asw.
