1: Convert 30 HP to 1 Superstructure Point
2: Convert 1 SCU = 50 tons
3: Convert Shields by giving it 2/1 for 10 SP, and 1/* (*=1 per additional 30 SP after that), and Max Shield Power is 1
Charging per 15 SP
4: Moving 1 Square (Ship Scale) = MPR 5/1, 2 = 4/1, 3 = 3/1, 4 = 2/1, 5 = 1/1, 6 = 1/2, 7 = 1/3, 8 = 1/4, 9 = 1/5
5: Hyperdrive is MPR x5 per Engine
6: Impulse Engine is 3 points per visible Thruster
7: Beam and Missile Damage is equal to 1 = 30 Damage (Fractions of this; - a residual 15 Damage, with some flexible interpretation,
become the Beam Weapon's Modifiers)
8: Weapon Range is, for each successive d10, starting from 1: D/E-F/G-H/J/P/S/T/U/X/Y/Z
9: If any Plasma Charts are applicable, use RL-1/RL-2/RL-3 for Smaller Ones, any others get AMPB
10: Power Cost is 1 for Proton Torpedoes and most missiles, 2 for Concussion Missiles
For ICON, Superstructure is x3.6, Resistance is 1 per 15 Threshold, Shield Protection is x2.4 the Max Shield Power,
Spread is 2 for launchers, multiply Total Power x3 for Power, Multiply Beam Damage x2 (x3 if Weapon has 'Heavy' in the title),
and give Missile Weapons 5 Damage per 2d10 in Damage
For both systems, Crew, Passenger and Shuttle Counts remain the same. Give ships Corvette (Size 3, Class IV-V) and up Tractor Beams
in blocks of 2, and give for Computers 20 WDF (STCS) or 1 (ICON), 2 of each make 1 Core, and have 2-6 pairings for larger ships.
Here, indeed is a way to convert Star Wars D20 Ships to either FASA or LUG's Ship Combat Systems.
It is rough, and in all likelihood, many of the larger ships are going to be even
larger and more advancex
