Several thoughts floating around my brain on this:

1) There are historical examples of situations in which the superior force (at least on "paper") was outmatched by the inability to close range. (One example is Troubridge's pursuit of the Goeben in 1914.)

2) However, issue #1 should be mitigated by the constraints of the wargaming table. Goeben was considered a superior force by the Brits because she could keep the range open indefinitely; in your situation, the Hyperions should have been able to close the range within a couple turns, since the White Stars are restrained by the board edge, right?

3) Regardless, point values 400 to 320 are not "pretty similar"... That's the equivalent of a nearly 60% increase in firepower!

A Whitestar should beat a Hyperion every time, and a well flown one should be able to handle a single flight of fighters as well. Still, an engine rating of 13 seems a wee bit on the high side, even for a vessel that flies "at the speed of plot." I guess it would depend on the baseline ranges for the weapons involved. But I agree with the earlier response that it sounds like it just done what a Whitestar should do! Between the long range of its main beam weapon, its stealth characteristics, along with its agility and speed, it would probably take a series of improbably lucky shots for a Hyperion to win (even if the WS captain strayed too close).The arcs of a Hyperion's heavy weapons are so limited that a WS should be able to use broadside passes to avoid getting shot at and pivots to bring its own weapons to bear. This tactic would work even on a fixed map if the WS is patient.
Cheers,

I haven't done fighters yet, so when I do the hyperion points will go up to meet the WS.  I think this will help, but as it stand they should still stand a chance.

Oh, I didn't realise that.  I just saw it had a jammer and gave it stealth.  I used to own B5 wars but never played it properly due to it taking so long.  I've read some of the rules recently for the conversions but not everything. 

I'll take off stealth in that case, cheers!

Countermeasures is enough to portray the jammer.

Thanks for another view on this.  I'm tending to lean your way on this.  I'm going to first test the speed changes and then make a decision on stealth.  I think I'd rather avoid taking into account power issues that were present in B5Wars as that's adding complexity.  I'll read up on the B5 wars rules and decide then, but I think I'd rather keep all the tech available on a ship and not go into minute details.

The Earth Hyperion was a very old ship when the White Stars came out.
They should probably be outmatched.
BUT the white stars were pretty small ships perhaps a lucky shot might take one out?

Here's my formula for engine conversions from B5 Wars.  Note that the turn cost and turn delay numbers are like fractions in B5W so you need the decimal version to put into the formula below. 

[Engine Power] / ["Acc/Dec" Cost]
+
([Engine Power] / [Turn Cost]) / 20
+
(10 / [Turn Delay]) / 20
=
Round to nearest whole number
=
TOTAL ENGINE RATING

So a White Star is:

12 / 2 = 6
+
(12 / 0.333) / 20 = 1.8
+
(10 / 0.333) / 20 = 1.5
=
TOTAL = 9.3 = 9 Engines

BTW, how do you determine fighters speed?

Marc

I simply took free thrust and it looked a bit fast. I will try something like you did. Maybe decide that the Starfury is the 'medium fighter' (currentl speed 10 att 5+ with nothing special and work out other fighters on this basis.
