The Klingon D-7/K'tinga class is the same in "Unexpected" as it is in Deep Space Nine (and although that was apparently a last-minute substitute in ENT, the alternate Klingon ship model looked virtually identical to the D-7 too).
It had similar lines, but I certainly wouldn't call it "virtually identical", any more than I would say the original pre-refit 1701 looked "virtually identical" to the refit 1701, even though they had similar lines as well.
I was so hopeful that CBS would have decided to replace the K'tinga
with the D4 in that ep when ENT season 1 was released on blu-ray. I should have known better.
