Hmm, after watching RotJ again, with my finger on the slow button, I think I may have to re-think my position. Originally, I'd assumed that the wingless and the Liberty represented the majority classes of Mon Cal ships at Endor.
I assumed that
these Mon Cal shipswere wingless Liberty-types. However, with the perspective that you get seeing Akbar on his bridge,
shown here, I think that the two ships shown in the pic of the Imperial bridge may indeed be Home One type craft. Add to it, yet another Home One type shown on the other side of the Executor after the SSD's bridge is taken out,
shown here, and the possibility of the second craft destroyed by the deathstar being a Home One-type, and you have a total of 4 Starcruiser level ships at Endor.
Now, as far as I can tell, you have atleast 2 Liberty-types at Endor. One, the Liberty, was destroyed by the Deathstar, the other is shown duking it out with a SD at point blank range,
shown here. On the wingless Liberty-type, there is definately one, but since one dosen't get destroyed and then they show another one, I can't confirm that the wingless we see in a couple of shots, are not the same ship.
However, there seems to be atleast 3 more unidentifiable Mon Cal ships behind the two Home One-types in the scene on the Executor bridge
, shown here,that don't seem to have the wings attached. They could be more Home One-types or escorting wingless Liberty-types.
So we have atleast;
4 Home One types at the battle of Endor
2 Liberty types
1 wingless type (or Liberty sub type)
Perhaps 3 unknown types.
So perhaps when Akbar is saying 'cruisers' he does in fact mean his Starcruisers, while the Liberty-types and the other wingless-type are the escorts for the Cruisers. This would help explain why the rebel fleet was so successful against the Executor, what with atleast 3 Starcruisers pounding it, plus their escorts.
I also noted, that not one Mon Cal ship was destroyed by anything, minus the Deathstar, while atleast two Stardestroyers got taken out by rebel ships. One particularly by a Home One-type Starcruiser, while Akbar is ordering a concentration of all fire power against the Executor,
shown here.
Result; the Liberty style Mon Cal craft may indeed be Stardestroyers (perhaps such craft are later retermed Stardefender for political reasons) while the true Mon Cal cruisers are indeed Starcruisers, though at ~3km they're at the lower end of the scale.
While I'm on the issue of the battle, where is the mention of HQ frigate. I was just watching the battle and Wedge says's 'they're heading for the medical frigate.'?
