My thought on the video is this:
Ignore the "end of century stuff."
This could be while the SDF-1 is on its way back to Earth.
The CVS-101 class are huge, 180 meters longer than an Nimitz. It is possible (though highly unlikely) that a OTC enhance F-22 might be made operable from its decks since the longer takeoff distance would lower the nose gear load. Also, given the timeline, it is possible that some F-22s might still be in limited service and that in the SDFM timeline a carrier variant was put to use.
The Regults could have been leftovers from the original attack on the SDF-1, hiding out and waging guerilla war on Earth.
The CVS-102 (rushed into service and barely operational) was sent to intercept with whatever they had on hand, the F-22s, Tomahawks, VF-1A-4. The pilot's flight suit even works because if he was an atmo only pilot, why would he need the space suit?
It is also possible that this video takes place post Space War 1, the CVS-101 has been pulled from the rebuilt Macross and recommissioned. The UN Spacy is putting so much into the Megaroad fleet that local defense is using older hardware, read whatever they can find and field. Based on the look of the damaged area this takes place in, with multiple huge blast craters, that is actually more my bet, especially since the Tomahawks look like rebel units as well, since they are attacking the F-22s.
Another possibility. Given that so many of the shots are familiar ones, maybe this was put together as a bid or attempt to convince SK/BW/Bandai to make a Macross the First Animation. Even the Half Gerwalk pose as the end is reminiscent of pose of Skull-1 at the end of SW-1.
