I've been discussing destroyers with Thirdfain. He has suggested that the discussion be moved here so that we all can weigh on it.
I start with this, contesting his claim that destroyers have very short range.

Thirdfain wrote:Give me historical examples. That'll count.
Adrian wrote:Pick an example from the allowed time period, please? 1892 is the cut-off in terms of capability. Havock does not fit within that range; the only really good example which does is an old Spanish boat (whose name I can't remember, Destructor, I think,) which was launched in the late 1880's.
Game-legal example, please
The tone of the reply the follows is unwarranted. I was going to change it, but Thirdfain got to it before I could delete it and write it over.
Adrian wrote:The technology difference between the British who launched Havock and the nations we're starting with is nil. Fact of the matter is that prior to the Havok class TBDs were rare, very rare. The Spanish destroyer? Well, they only built one. Hell, I wouldn't be surprised if prior to the Havock class the only TBDs in the world were Destructor and Kotaka. The reason? Shitty range. If we're going to employ TBDs on a large scale (and by that I mean a lot more than a couple of prototypes on opposite sides of the world) then we need to base them on Havock, not Destructor.
Of course, the tone in Thirdfain's reply was definitely warranted in light of what he recieved.
Thirdfain wrote:Too. Fucking. Bad. These are based on Destructor and Katoka, with all the limitations that implies. TBD's are supposed to be a new idea, very much in it's infancy. These aren't the destroyers of World War 1. Live with it.
Adrian wrote:Damn, and just when I was about to bring the hostility in my message way down.
Anyway, there's no data on how much range they have. But it depends a lot on cruising speed and fuel bunkerage. I made a ship on SpringSharp (well, it's probably not an infallible program, but it seems pretty good) that's as close as I can to Destructor based on the little data avaliable. To get as much range as Havock with similar cruising speed you need between 40-50 tons of fuel. This seems well within the capabilities of the desgins of the era.
And I know these aren't the destroyers of the Great War, I'm arguing for the destroyers of the late Victorian era. Which have pretty good range.

So here we are.
My position as it stands now:
I think that torpedo boat destroyers are not as short-ranged as Thirdfain thinks. For one thing, range is very highly dependent on cruising speeds. Going faster kills range, slower lengthens range. One should also take notice of what is meant by "short range" exactly. TBDs are primarily meant to escort capital ships. During this time period the max range of the ships of the line would have been ~5000 nm. If the destroyers can only manage 1500-2000 nm they are comparatively short-ranged.
1890 is something of a difficult year, since it's in the gap between the invention of the Torpedo Boat, and the effective Destroyers with decent range needed to counter them. Taking a look at people's OOBs in general, it seems like the general player assumption is that their destroyers will be capable of keeping up with their battle-line. Since most have a number of destroyers that's about right for the purpose of forming a screening force for the main combatants. With the Great War in Europe, the concept of the destroyer should be well proven by now, and even far away colonies know of it.
What I'm trying to say is, in the real 1890 there were no effective TBDs yet. Not for another three years. However, it is mostly because nobody bothered to build any rather than technological barriers. There's been a huge war in this alternate time-line, and even if the faraway colonies are incapable of reproducing most of the advances that occured during this war, such simple ideas as "torpedo boats work" and "so do torpedo boat destroyers" should have disseminated. Like I said, getting good range in these a TBD is not hard. 40-50 tons of coal allows a 380-ton ship to have a range of ~3000 nm at a decent cruising speed.
