The K't'inga was the "new" Klingon ship designed for "The Motion Picture". It really is substantially similar to the D7. It's supposed to be a new ship model, rather than a retrofitted older craft, but it bears a lot closer resemblance to the D7 than does the "refitted" enterprise to its appearance in the original series.

The D7 Cruiser was the standard enemy ship of the original Star Trek series. Designed by Walter "Matt" Jeffries to evoke the threatening lines of a manta-ray these ships became the instantly recognizable face of the enemy.
