DS9: "Valiant" features a Jem'Hadar battleship that is purportedly twice as large and three times as strong as a Federation Galaxy class. We never see this vessel again until DS9: "What You Leave Behind" (WYLB). In the shot with the Dominion fleet in Cardassia's orbit we can spot several of these massive ships, but now they are even much bigger, perhaps 5km long, compared any of the other ships. The first problem is that the huge ship (sometimes called "confrontation cruiser" in fandom) is exactly the same model as the smaller one from "Valiant", but scaling considerations would forbid the two real ships to be the same design. The second question is if such incredibly huge ships can exist at all and where they suddenly come from.

The Jem'Hadar battlecruiser is a large warship that repeatedly appeared during the Dominion War arc of DS9. Fans quickly found out that the first ships as seen in DS9: "In Purgatory's Shadow" were unlike the variant which we could look at more in detail in later episodes. The first variant is routinely nicknamed "V-type" because of its wing and nacelle arrangement that looks like a "V" in a straight fore view. This article investigates whether a distinct V-type exists at all, how often it shows up and whether there are possibly more variations aside from the nacelle struts. Here is a list of all battlecruiser appearances in chronological order:

1. DS9: "In Purgatory's Shadow"
2. DS9: "By Inferno's Light"
3. DS9: "Ties of Blood and Water"
4. DS9: "In the Cards"
5. DS9: "Call to Arms"
6. DS9: "A Time to Stand"
7. DS9: "Sons and Daughters"
8. DS9: "Behind the Lines"
9. DS9: "Favor the Bold"
10. DS9: "Sacrifice of Angels"
11. DS9: "Shadows and Symbols"
12. DS9: "The Changing Face of Evil"
13. DS9: "What You Leave Behind"
