No, I think it's only T2. But comes with a cool console.
But there is already a Tier 2 Saber. How can it be a refit if there is already one at that level with the same stats? Also, how is a Tier 1 version of a tier two ship a refit? A refit SHOULD be for either tier 4 or 5!
Yes it is T2.5.
There is a picture of it here. (not very good. also I'm way too lazy to log in an... Eh I got a few minutes to kill. Will update shortly.)
And at level 51 it evolves into a Fleet Escort. :p
