In the end I think it comes down what the TL of the J-drive actually is.

If a J-drive's TL is 13 then it will never ever do better than J4 no matter how much displacement is reduced.

However, if the TL is 15 then it can & will make J6, even if the original design only did J4, *if* the displacement could be reduced accordingly

Howdy Phil,


I think you are saying that a J5 drive is capable of making a 5 parsec jump using either CT LBB 2 or cross referencing hull tonnage to jump 5 rating/performance to Drive Type or CT LBB HG 2e using the equation of Hull tonnage x a percentage of the hull required.


I, if I'm understanding correctly, agree that a J5 drive is the same drive in either CT LBB 2 or CT LBB 5 HG 2e.

It would seem then that a lot of folks decided that J-range could go down but not up.

The group I was in, which was formed *after* CT HG v2 came out, figured it worked both ways.

To us it didn't matter whether,  for example, the Gazelle's J-drive  was originally designed to a max-DT config or a max-J config.
Either way it was the same J-drive.
