Contra-Gravitronic FTL Drives - Rules and Stats
Posted: Thu Dec 19, 2019 7:55 pm
So in various posts over the last probably year or so I’ve discussed ships, tactics, and most recently system/planetary defense and defense platforms. Now in all of those discussions one thing that has come up is the use of FTL in combat and it was quickly apparent that we are all operating under very different assumptions about how it operates. Most of my assumptions were based on how I had been using it in game for the last 20 years so I went through all the books to try and gather just the canon information and there isn’t much.
These are all the Rules I found:
DB 2: Phase World, Pg. 152-153
This is the bulk of information that we have on CG drives and really all it provides is a description of how the drives work in a “scientific” sense and really only provides one rule:
- FTL must be shut down a minimum of 10,000 miles from a planet but twice that is “safer” but how it is safer is undefined.
Note: After discussion this rule may only apply to approaching a planet with an atmosphere and not leaving one.
DB 3: Phase World SB, Pg. 6-7
The only material in this book is the rule that ships in intergalactic space can move at 5 times it’s listed speed.
Questions remaining:
- How far away from the galaxy do you have to be for this speed to kick in?
- Is it a gradual increase (i.e. at a few hundred lightyears you can do twice the listed speed and then at another distance triple, and so on) or is it immediate.
This is important information to have because ships can go “up” or “down” or above or below the width of a galaxy and fly place to place at 5 times listed speed.
DB 6: Three Galaxies, Pg. 131-133
The only specific information in this book is a list of prices for FTL engines. This list appears to be uniform and no way seems dependant on ship size or mass. This means that the same 75 million credit CG-F drive can move a Proctor fighter at 6 LYpH can also be used for a Protector class Battleship.
Questions remaining:
- What is the weight and size of a drive? So how much space in the ship is taken up by the drive?
If the same drive works in both a Black Eagle and a Packmaster then it must be tiny.
DB 13: Fleets of the Three Galaxies, Pg. 11-12
The only material in this book that I have found is basic rules for combat at FTL.
We also get the basic understanding that Dreadnought class ships require a very specific drive system that is enormously more expensive than drives in smaller ships.
Discussion Topics
First, if anyone finds information in the books that I missed please let me know and I will add it to the discussion.
Second, here is a list of questions that I think need to be answered about FTL drives to determine both their tactical and strategic uses:
1- How long does it take to activate an FTL drive? Is it always hot and ready to go or do you have to “spin it up”? At the very least you would probably have to set a course with nav space.
2- How is the 10,000 mile safe zone determined? Is it determined by gravity or mass? Does jupiter and the sun have the same 10,000 mile zone as an earth sized planet?
3- What happens when you activate the drive early or deactivate it late? Does it just shut down or not work? Does it take damage or blow up?
4- What is meant by “twice that (meaning 20,000 miles) is safer”? Can there be a negative effect for coming out of or going into FTL between 10k and 20k miles?
5- How accurate is your “exit” from FTL and how fast are you traveling when you leave? Can you exit exactly 100 feet off the bow of another ship or is it a wide exit point
6- How far away from the galaxy do you have to be for this speed to kick in and is it a gradual or immediate effect?
7- What is the cost, weight and size of a drive? Do you use the prices in DB 6 as is or with mods? Is there a power requirement?
