Annotations L'Rell and Voq present this supposedly new ship type as a holographic projection in DIS: "Point of Light". Voq is going to oversee the production. Despite his sudden departure, several ships of the type are built. We can see one D7 in DIS: "Through the Valley of Shadows" and several more in "Such Sweet Sorrow II". The "new" D7 roughly retains the shapes of the ship from TOS. Concept artist Ryan Dening changed the nacelle style to be more in line with Discovery-Klingon design. The surface details (created by Scott Schneider) too are very different. The countless lights in "Through the Valley of Shadows" insinuate the ship could be several kilometers long, but the "reimagination" was scaled up to "only" about 10 times the volume of the TOS version. It is clear that the presentation of the "new" D7 and the reasoning that the ship unites the Klingons breaks the fourth wall. The return to the traditional design is very clearly a response to the criticism of the bizarre ships of season 1, which didn't look Klingon at all. They are retroactively declared individual designs of the single houses that for some reason existed in just one era (although T'Kuvma's ship was said to be ancient) and that for some other reason will all be scrapped within a few years. The "new" D7 also invalidates the designation of the Sech class (see below) as "D7" in "Choose Your Pain", which happened at a time when no one in the production seemed to have a problem with Discovery being a total reboot on the visual side. It seems odd that the Klingons would name their new ship "D7", which sounds more like a Federation code name (and actually was one in "Choose Your Pain"). Considering that the K't'inga may be the authentic Klingon name of the class that the Federation occasionally refers to as "D7" (or perhaps of an upgrade that the Federation calls "D8"?), it may have made a bit more sense to name the "Point of Light" ship "K't'inga". Perhaps the idea was that Voq-Tyler came up with the name and also with the design (considering that it resembles Federation ships, unlike the ones of season 1)? However, bearing in mind that Klingon ships always looked like the "new" D7, also in Enterprise, this doesn't make much sense - unless it is the intention of Discovery to continue to disregard ENT. The reboot D7 is 503.53m long, as opposed to 224m of the original ship. If it were not for the size issue, it might be possible to reconcile this D7, as the only DIS Klingon ship type, with the classic Klingon design lineage.
