I'm not trying to derail, I'll drop back to lurking this one in just a mo...
But...
Am I the only one that finds it somewhat disheartening that so much of this talk revolves around slapping "high tech" names on historical battles/ships and rehashing the past? Why not play historical tabletop games? Why bring it into Traveller?
OK, I know that many see the OTU as having historical parallels but how far is too far?
Where's the fiction in this science fiction?
(starts rooting thru the deepest drawers for the Nomex suit, I know its here somewhere...)
This is a sci fi board. If they want to flame you, I don't think your Nomex is going to help: they'll bring out the high temperature plasma.
And, your point is valid, though I wouldn't be disheartened by it. It's just that a lot of us come from a fairly wide gaming-and-miscellaneous background and can't help dragging in those old examples when trying to explain ideas.
When push comes to shove, a lot of sci fi draws on old examples - fighters, battleships, and so forth - if for no other reason than to present stories that have some familiar paradigms for the reader to latch onto. A story about amorphous clouds of nanobots warring with each other beyond our perception would be entertaining, but it doesn't grab you the same way a story about men and women winning through by wit and daring grabs you - even though pure logistics wins more wars than wit or daring.
As Mr. Whipsnade has mentioned several times - HG ship combat is not the age of sail in space, it is not ironclad era or predreadnaught or WW1.
It is ship to ship combat using the technology that underpins the Traveller setting across the entire TL range of 7 to 15.
The only way to appreciate HG is to play it, properly and fully. Build fleets, not ships, at every TL. Try to find the strengths and weaknesses of fleet design at the various TLs.
I don't care for any large ship, call it what you will. A large ship is an expensive target and easy to hit. A small ship is a less expensive target and harder to hit.
I joined in on this because a certain prevailing thought was that BBs should work.
ANY one of us, given half the Imperial Fleet budget, could destroy the Empire in short order.
Assume we get half the credit value of ANY Imperial fleet in any given battle. It could even be done for a whole lot less.
I would agree with this sentiment except that High Guard does not exist in a vacuum. As a part of the Traveller Milieu, it creates a rules environment that starkly contradicts the canon depiction of the universe of the Imperium and her neighbors. A lot of people are irritated by that and would prefer to find some way to resolve the contradictions.
I like High Guard by itself, and there's no reason to believe battleships
should dominate - that idea was pretty well retired on Dec. 7, 1941 (I did warn you, Hiro:devil

, and any holdouts need only look at the fate of Yamato to understand that bigger is not always going to be better. However, from CT Supplement 9 through FFW and Invasion Earth, down to MegaTrav's Fighting Ships of the Shattered Imperium, and in more mentions in more supplements than can be described here, the universe inhabited by the Imperium is painted as a universe where bigger is better. If my intention is to fight the Imperium verses the Zhodani, then I either adjust those rules to fit that paradigm or I chuck High Guard completely and assume it has nothing to do with the Traveller universe - which leaves me without a big-ship rules set.
