Here is my first thought on a SFB Fed CA with the R refit.

CONSTITUTION-class FEDERATION HEAVY CRUISER ( CAR ) ( 183 )

Hull: 8 7 6 5 4 3 2 1
Engines:  5 5 4 4 3 2 2 1
Screens:  3 3 3 2 2 2 1 1
Weapons:  1 [ XY ]  2 [ XY ]  3 [ XY ]  4 [ YZ ]  5 [ YZ ]  6 [ Y ]
[X] Photon Torpedo [4/8/12, 4+ 1/1/2, Slow-Firing; Variable IMP]
[AB] [AB] [AB] [AB]
[Y] Phaser Type I [6/12/18, 3+ 1/1/1, Doubled Range Mods]
[GHI] [GHI] [AC] [AC] [BD] [BD] [EF] [EF]
[Z] Phaser Type III [3/6/9, 3+ 1/1/1, Doubled Range Mods]
[ABCDEF] [ABCDEF]
Special:  Hyperdrive; Fire Control; Marines (10); Science (80); Teleporters (2); Transport (25)

From remembering SFB back in the day, I'd switch around the defining characteristics of the Torps and the Phasers. 

Range affected Torps ability to hit from almost-guaranteed to don't-bother-firing.  But they always did the same damage.  Give them Doubled Range Mods (and Slow Firing). 

Phasers had the same chance to hit, but range made them do less damage.  Call that No Range Modifiers and Range Based Damage.

I don't see how to do Overloaded Torps though.  Might be an interesting possibility for a weapon mod.  Variable Power or something.  Can fire at 2xDmg, but then can't fire next turn.  Optional modifiers could be a powerful design thing.  40K plasma works the same way.

Yeah, but then you'd have to have a separate weapon called Overloaded Photons.  That's what made me come up with the Fire-time Options thread.  It would be cool if "2x Damage, Carronade" was a mode on the main weapon itself.

Well here is what I have come up with based loosely on the Star Fleet battles designs.

What I like about Star Fleet battles is that the Klingon battle cruiser and the Fed. Heavy cruisers are evenly matched.

In Starfleet battles the Klingon ship is more maneuverable then the Fed ship so I made the Klingon ship a little faster.

In every game system they rate the shields lower on the Klingon ship so I did the same.

The disruptors are long ranged weapons so I gave them Inverted range modifiers, nothing in SFB suggests this it's just something I wanted the weapon to have.

Phasers : I loved the Idea of Ranged Based Damage as suggested by boneless and no range mods. I did not use ranged based damage, but ranged based impact instead as it does the same thing as damage but it also effects the shields.

I also used the Photon torpedoes as suggested by Boneless.

Japridemore had great ideas using marines and teleporters, Science areas Hull size and Screens are a great idea but would prolong any convention game.

The Klingon has has a +1 Tech level for engines and weapons, this makes sense as they are an older space faring race. I also needed space to cram all that stuff in a 7 Hull

My Ideas about the two ships

The fed's need to get close to make full use of their Phaser I's and torps
The Klingon ship needs to make use of its long-range weapons and speed.
Once the Klingon is in Photon range he is toast as the photons will eat him up.
The Klingon players will need to use speed and maneuver to their advantage.

Most of the weapons and arcs are as per SFB

Let me know what you think!

Steve... 5 shields?

This is for a convention scenario, they only have a short amount of time to play.   Save the 5 shields for X ships. 

Phasers with a longer range than Photon Torpedoes?

I'm not a SFB player, but that's not how they were portrayed in the series. They were only fired at what was apparently "long" range and in spreads - giving the impression that they were powerful,but slow and relatively inaccurate (like their namesakes). And they were never(?) used simultaneously with phasers - which you could argue was for energy management concerns.

Once the infighting began it was always Phasers. And Phasers were never mentioned as being used at "long" range, In fact that's what differentiates Star Trek from B5 - the emphasis on ship-to-ship dogfights at relatively short ranges rather than battlelines slugging it out at long ranges.

In the game StarFleet Battles, Type One phasers, which is what Federation ships have, can fire out to 75 hexes.  :shock:
However, they don't do much damage at long range.  Photon torpedoes only fire out to 30 hexes.
In the early days, SFB was fun and my friends & I played often.  It soon deteriorated to Rules-quest and became drugery; not fun...
We used to design our own ships and guestimate the point value.  Its nice to be able to have an exact value, and many more weapon options here using SAE.
