1. The Bird-of-Prey can be seen in DIS: "Battle at the Binary Stars", "The Butcher's Knife Cares Not for the Lamb's Cry", "Lethe", "Si Vis Pacem, Para Bellum" and "Will You Take My Hand?". In "Lethe", two of the ships are docked to a ground-based station. In "Will You Take My Hand?", we can see a large Klingon logo on a Bird-of-Prey that the ship type previously didn't seem to have.
2. The design is a completely different one than the Bird-of-Prey known since "Star Trek III" or its predecessor from Star Trek Enterprise. We may argue that "Bird-of-Prey" is just a generic designation, but it is quite obvious that in the reimagined world of Discovery this new BoP is meant to replace the familiar one from the old Star Trek (just like we never see any old-style Klingons in the series either).

1. We can spot the Batlh class a couple of times in DIS: "Battle at the Binary Stars". The class also appears in "Will You Take My Hand?".
2. This ship is occasionally spelled "Bstlh", but "Batlh" is correct. {batlh} means "honor" or "honorably." It refers to inherent honor, like strength of character, rather than to honors that have been conveyed, as symbolized by a medal or award.

1. This ship class is likely present in DIS: "Battle at the Binary Stars". In any case, we can clearly identify a bortaS bir (aka Qatlh) in "The Butcher's Knife Cares Not for the Lamb's Cry" (as Kol's ship) as well as in "Will You Take My Hand?".
2. According to the latest scale chart, the class is not named "Qatlh" but "bortaS bir" (cold revenge). Eaglemoss calls the class a "battlecruiser".
3. {Qatlh} means "be difficult."

We can see the class in DIS: "Battle at the Binary Stars". The Chargh looks similar as the Jach class, but the identification of the Chargh is positive. The Chargh, rather than the Jach, is probably also visible in "Si Vis Pacem, Para Bellum" and "Will You Take My Hand?".
1. The two Charghs in "Si Vis Pacem, Para Bellum" are referred to as "battlecruisers".
2. {chargh} means "conquer."

1. In DIS: "Battle at the Binary Stars", the cloaked cleave ship rams the USS Europa. The ship reappears in "Such Sweet Sorrow II".
2. It is unknown whether the cleave ship was designed for the very purpose to remain cloaked and ram enemy ships during a battle.
3. The side view is a design sketch and may not correctly reproduce the shape of the ship as it appeared on screen.

1. 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".
2. 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.
3. 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.
4. 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.
5. 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 rather "D8" because there are visual differences?), 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.
6. The same reimagined design is also used in Strange New Worlds, whereas the Klingons themselves return to a classic look in the series. We can see the ship type in SNW: "The Broken Circle" and "Subspace Rhapsody". On the latter occasion it is called "K't'inga class", although in classic Trek D7 and K't'inga are two distinct designs, with the latter probably being more recent and replacing the D7 after the TOS era.
7. The reimagined 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.

1. The DaSpu' is among the ships that are clearly identifiable in DIS: "Battle at the Binary Stars".
2. {DaSpu'} means "bootspike."

1. The 'etlh class can be identified in the fleet of DIS: "Battle at the Binary Stars".
2. According to the latest scale chart, the class is not named "JejHa'" but "'etlh" (blade).
3. {jejHa'} means "be dull," but it's not a simple negation of {jej} "be sharp." The simple negation would be {jejbe'}, "be dull." Negation with {-Ha'} means the sharpness has been undone or done improperly, and probably indicates that it's about something you'd expect to be sharp, like a knife. Our guess is the word suggests the condition of a knife used so often it's become dull.

1. The Jach probably appears in DIS: "Battle at the Binary Stars". Since the Chargh is a very similar design, a positive identification of the Jach is hard though.
2. {jach} means "scream, cry out, shout, yell."

1. It seems likely that this ship class is present in DIS: "Battle at the Binary Stars". Since the Qoj, the Tlhapqa' (Qow') and the Veqlargh closely resemble each other, it is hard to identify the specific classes in the episode.
2. {Qoj} means "wage war."

2. According to the latest scale chart, the class is not named "Tlhapqa'" but "Qow'" (destroy) - or "Qaw" according to Eaglemoss.
3. {tlhapqa'} means "take again," {tlhap} meaning "take" and the ending {-qa'} meaning "do again" or "resume." In short, it means "take back" or "retrieve."

1. We can see the Qugh class in DIS: "Battle at the Binary Stars", "Si Vis Pacem, Para Bellum" and "Will You Take My Hand?".
2. This ship type is referred to as a "destroyer" in "Si Vis Pacem, Para Bellum", although it is much bigger than the two Chargh-class "battlecruisers" in the same episode.
3. {Qugh} means "disaster." It's also Kruge's name in Klingon.

1. The Sarcophagus ship appears in DIS: "The Vulcan Hello", "Battle at the Binary Stars", "The Butcher's Knife Cares Not for the Lamb's Cry", "Si Vis Pacem, Para Bellum" and "Into the Forest I Go".
2. It is unknown whether the Sarcophagus ship is a sui generis design or whether it used to be a standard type before it was phased out. In any case, it is the only such ship in service during the Klingon war against the Federation.
3. The visual effects in "Battle at the Binary Stars" and "Into the Forest I Go" put the Sarcophagus in the 2 kilometers size range, a size which has been confirmed by Eaglemoss.

1. We can see this ship design in DIS: "Battle at the Binary Stars" and "Choose Your Pain".
2. The Sech class is called "D7" in "Choose Your Pain". Since this is a very definite designation, it is clear that Discovery's starships (of the first season) have no continuity with those of the "old" Prime Timeline. In the episode, the ship (a battlecruiser in the old Star Trek) is occasionally referred to as as "prisoner transport", although this most likely isn't the primary purpose of the design, even in Discovery's version of history.
3. In direct contradiction to "Choose Your Pain", L'Rell and Voq present the "new D7" (see above) in DIS: "Point of Light". In contrast to the Sech, this "new" ship looks much like the old D7 from TOS and is quite obviously meant to reconcile the messed up design lineage from DIS with the one of classic Trek. This invalidates the idea that the Sech could be a D7, although explicitly stated in the episode.
4. {Sech} means "torch."

1. This ship was secretly built underneath the surface of Cajitar IV in SNW: "The Broken Circle" and later launched from there. Spock ordered to destroy it before it could attack the Klingon D7.
2. The design uses the characteristic saucer of a Crossfield class with the gaps in it, which is why Jenna Mitchell mistakenly identifies it as this class before it is discovered that it was cobbled together. Alas, the very same design appeared earlier in the episode docked to Starbase 1, so it can't have been an unknown configuration. Size estimation based on known components of the ship.
3. The Broken Circle is purportedly a joint syndicate of Klingons and humans to mine dilithium on Cajitar IV and boost its price. But we only see Klingons all the time. While this appears to make sense, considering that the planet is shared, would the entire staff that is building the ship (in secret!) switch every month?
