Sorry for the delay in replying, gents... it's been absolutely bonkers out here for the past few days.glitterboy2098 wrote:as far as ground troops getting off..
All good ideas, IMO... though the first three seem inconsistent with the depictions of the UEEF's typical approach to planetary assault operations.
They seem to be quite fond of having their ships stand off in orbit for orbit-to-surface bombardment and sending down dropships and independent fighters.

The CG model in the film doesn't support that size... which is why, for the last several posts,
ShadowLogan and I have been mulling over the implications of the
Ikazuchi-class being much smaller than indicated. If the ship were as big as the stats say it is, no problems exist with the amidships hangar deck... but the Alpha fighters would have to be eight times their official size, and the crew would all have to be four meter tall giants, which of course doesn't quite work.

How do they get off the ship? That is actually provided for us in official RT material:
-"
The front of the vessel features a heavily armored bow that can be used to ram enemy ships and
twin bay doors for rapid frontal deployment."
Whether that door actually exists is another matter entirely... it's never been depicted, its existence would kind of logically preclude the practicality of the launch bays (either version), and OSM didn't have any such feature. Sufficed to say, I don't entirely buy it, especially in light of the ship not having a barrier system and being so fragile that blunt Invid claws and low-velocity collisions can cause massive gaping hull breaches. It doesn't seem like a ship suited to ramming, especially as it has no engines oriented for reversing. (The
Star Trek problem of how do you stop when all of your engines are pointing in the same direction...)

One other reason, which proves plot-critical to the
Shadow Chronicles OVA but was also demonstrated quite readily in the OSM/series... these ships are heavily automated, to such an extent that even the largest ships can be operated by barely enough people to form a baseball team. Modern warships have crews of thousands because they NEED crews that huge to maintain and operate their various systems, which often require significant manual labor. Large warships like aircraft carriers normally require a bridge crew of dozens... the typical bridge crew of a UEEF warship in RTSC or New Generation-era
Robotech is just seven (the SDF-4 and
Icarus) counting the captain. The
Garfish-class bridge in the series only seats four, including the captain.

I have reviewed the documentation in AotSC for the Ikazuchi's depicted size, along with the Alpha. The TSC depiction of the Ikazuchi actually is closer to what AotSC states than the OSM. It isn't a perfect match mind you, but it does appear that AotSC/Infopedia could be correct FOR TSC's depiction, but not NGs*.
I've reviewed my own math and checked a few other things, and I did make a slight upwards adjustment but not much of one.
We know, from the visuals of the OVA, that the
Ikazuchi-class's launch bays have replaced the 6*4 racks of battloids with ten launch tubes for fighter mode instead, and that each is just barely wide enough to permit the egress of an Alpha fighter. I redid my measurements digitally and came up with approximately 7.25 launch bays worth of length to the ship (fins excluded), as I had not previously counted that bulge at the back of the engine section. Another thing I had to revise was the between-tube padding. The outermost tubes, based on the visual, directly butt up against the sides of the launch bay rather than having free space on that side, which shrinks the footprint of the bay as well.
The new wrinkle I discovered while I was being incredibly bored in a doctor's waiting room this morning is that the CG model Alpha does not match the proportions given in stats for either the OSM or the
Robotech version. The OSM proportions should give the aircraft a length to width ratio of 1.6 to 1 (10.25m long, 6.4m wingspan). The
Robotech proportions are 1.25 to 1 (10.25m long and 8.2m wingspan). The CG model's proportions are approximately 1.422 to 1, giving the RTSC Alpha Fighter CG model a wingspan of 7.2m, not 8.2. It's closer to the OSM size than RT's, but only by about 20cm. (In so doing, I also noticed they changed the proportions of the aircraft's wings, being more of a cropped delta than the original show's cranked arrow.)
Here's how the numbers pan out under the various assumptions of the Alpha's size:
For the OSM wingspan of 6.4m and RTSC version of the shipThe five tubes, being approximately 6.5m wide each, are spaced by four pillars of approximately 3/4 of a meter to 1 meter in width, but not on the outside edge. This gives the interior of the bay an approximate width of 36.5m, and the exterior dimension of approximately 42m. This gives the ship, which is approximately 7 1/4 bays long in the CG model side view (measured from the exterior corner of the hexagonal losenge-shaped bay), a length of approximately 304.5m if one doesn't count the various antennae and fins which the RT stats list separately. This is almost bang-on the OSM size.
u]For the CG model's proportional wingspan and RTSC version of the ship[/u]The five tubes are approximately 7.3m wide in this, and spaced by four pillars of approximately a meter in width between bays. The interior width of the bay space is now 40.5m, and the exterior is approximately 46m at its widest extent. That puts the total length of the ship at around 333.6m long.
For the RT stats wingspan and the RTSC version of the shipThe five tubes are approximately 8.3m wide, same spacing as above. That puts the interior width of the bay at ~45.5m, and the exterior at 51m, for a total length of 370m.
All of that is a LONG way from the RT stats size for the ship of over 600m.
