T-45 Goshawk

Can anyone tell me what the roll rate and maybe the g-rating is for the T-45 Goshawk?

The T-45 Goshawk was developed from the Hawk 60 airframe, which has a G rating of -4/+8 (sounds a bit much to me)

The Goshawk airframe I presume must of been strengthened for naval use (landing gear, arrester hook etc) so I would say that the Goshawk has a lower G rating than -4/+8 probably -3/+6 (Which still seems quite high to me) but that

Yes the Goshawk airframe was strengthened for carrier operations; landing gear, tail hook, wing etc. I would think that would increase the G capability or at least stay the same. I mean, how many G's does an airframe take every time it hits the carrier deck? In Youtube videos I have seen of the Goshawk it looks pretty nimble. I would guess from those videos that it has a roll rate of at least somewhere in the neihborhood 150 degrees/second but I don't know for sure.

Not the airframe thought out on the Goshawk that has been strengthened I believe it is just the landing gear, and around the arrester hook area and also on the tie downs.

The extra weight of this would decrease the G limitations
For example all of this will be 4 times heavier at 4G and therefore will be putting greater load onto the airframe at this G than the original Hawk 60 Airframe becuase of the extra weight.

I don

Actualy I found some info on Google. It can do 180 degrees/second between .7 and .9 mach.

Nothing high about that when you look at others. The Alpha Jet is similar, although the UK operated examples are limited to only +6G. The Tucano is up to +6G (as is the Tutor), and the crew in those don't wear G-protection.

Google's first answer to my search for the Goshawk comes up with -3/+7.3
