That's why I wanted to convert them.  I made some stats for the Zandris IV stuff in X. Because I tried to stay to true to what was on the model and what the sculptor had come up with for FT stats they had a limited armament. They also kind of looked like they had AGBs too.

I got around to buying AE recently and was a little upset due to the lack of Armored Gun Batteries and Redundant Shielding.  Rather than complain though I took a little time to apply them in a manor similar to Armored Plating in AE.  Here's what I came up with minus filler/explanation text.

Armored Gun Batteries

The effect is to negate any damage roll result of 6, eliminating 50% of potential weapon damage.

In starship construction a ship with armored gun batteries has the Total SU Cost for each battery multiplied by a factor of x1.5. In addition, the Total SU Cost of each battery should be should be multiplied by a factor of x1.75 when calculating the ship's Battery ORAT values.

Redundant Shielding

The effect is to negate any damage roll result of 4, eliminating 50% of potential shield damage.

In starship construction a ship with redundant shielding has its Shield Factor multiplied by a factor of x1.5. In addition, the Shields value should be multiplied by a factor of x1.75 when calculating the Starship DRAT.

The SU mods for each (x1.5) was ported directly over from X.  I modified them to follow Armor Plating's example in not requiring an extra die roll.  This resulted in the two options being slightly better than the X version (negating hits 3/6 of the time as opposed to 2/6 of the time). I upped the ORAT value for the AGB's and theDRAT value for RS's by 1/6 to follow suite.

Thoughts and or criticism? Apologies if someone already came up with the same idea.
