An interestingly economical ship. Similar in concept to the RN's WW1 era "destroyer killers", IE the Arethusas, C class and D class, but with a more modern armament layout. These would make useful destroyer leaders I think.

Could you get 30 knots on similar displacement by reducing protection?

Yeah, speed costs length. All in all, that's not a bad ship though. The extra length could help with congestion, etc. and make for a little better ship.

My guess is, for ~3500 tons, you might be able to get splinter protection over the machinery spaces too. An interesting concept to me. It's not much more than an overgrown destroyer, but then again, that's ok.

I like that. I don't suppose the NUS would be interested in some export work for the Ottomans in the future though, huh? I can think of lots of useful roles for a ship like this in the Med and Red Seas.

[Jefgte]

...I can think of lots of useful roles for a ship like this in the Med and Red Seas.

& archipelago too.

[mentat]

  Agree - this size of ship very handy for Med - I looked at this last year

- and think at @ 28-29 knots and low seakeeping (it is the Med.) you can get a DD design with 5 x 150 mm (5 x 1) - and bit of armour (30/40mm) - for gun mounts + armour patch for Mags - a 'Destroyer Gunship'

  - not so robust as small CL - but much cheaper - can afford more - operate in small squadrons ....
