Uh, I just redocked my T10 to count the internals again thinking I could have made a mistake, but no I'm still counting the normal stock nine internals the T9 has, with an additional two C5 military slots?
C8
C7
C6
C5
C4
C4
C3
C3
C2
C5 MIL
C5 MIL
I mean, I've not flown my T9 in awhile, but I could have sworn thats what the T9 had as well? Minus the two C5 mil slots of course?
Not sure about the Internal count, as I do all this on my phone and it makes everything tricky, but I think you are right.
So, where does the difference in cargo come? With the 9 I can fit 5A Shields, throw on some boosters if I want, and get 300+ shields. More then enough to submit, boost, and high(low wake) out. With the T10 I can't use 5 shields because of the 1200t I am guessing. Therefore I end up with less cargo capacity.
TBH I haven't made a detailed study as ED Shipyard is tricky to do on my phone and a Corolis hasn't added the T10 yet.
I did go thru the process once for the T10 on ED Shipyard and I wasn't not impressed in particular with the high cost of the 10. Less cargo for a nothing speed increase and a couple of LY jump is hardly worth it with the money plus the ability to Engineer the 9. Even un-Engineered the 9 seems a better ship for trading.
But the T10 wasn't designed as a trader so no sweat, no burn, no complaints. If it was then we can get all fired up about the T10 Keelback.
