Afternoon PDT,
The system description text on Step 5: Add Weapons, Ammunition, and Other Equipment pp. 153-155 does not mention grav decks.
The examples in Step 5: Add Weapons, Ammunition, and Other Equipment provides the following:
Catalyst Game Labs 35004 Strategic Operations lists the tonnage in the example text and price on the Advanced Aerospace Unit Costs Table p. 159
1. Alliance Class Space Station p. 155 right column "..., and a 420-meter grav deck for the comfort of shipboard personnel (500 tons)."
2. Odyssey Class Jump ship p. 156 right column "...., 2 110-meter grav decks (100 tons each), ....",
3. McKenna Class Warship p. 157 left column "....Lynn also installs 3 grav decks - 2 at 45-meter diameter and 1 at 75 meter diameter - at 50-tons each...."
The Advanced Aerospace Unit Costs Table p. 159 lists the cost in C-bills for Grav Deck (under 100m diameter), Grav Deck (100-25mm diameter), and Grav Deck (over 250m diameter).
I did not find any updates in Strategic Operations Errata 2.0 Last Modified: 10/26/2011 indicating that a table to see if there was any information about a table similar to the one in FASA 1718 AT2 p. 74/FanPro 35011 AT2 Revised Edition p. 65 which has the following:
Grav Deck (<100 meter diameter) 50 tons
Grav Deck (150-250 meter diameter) 100 tons
Grav Deck (>250 meter diameter) 500 tons
Is there a table that lists the same information for the Grav Decks cover in FASA AT2 and FanPro AT2 Revised Edition?
