Good stuff, very interesting.

Thanks. :)

And here's the next pair.

ATL Delta III LV. That sits somewhere between OTL Delta II and OTL Delta III. The key difference being that it's rather more successful than OTL Delta III. Built shortly after STS disaster that brings back the ELVs for NASA and DoD.

ATL Titan V LV. With 5/7 Seg. Titan SRBs, STS SSMEs and Centaur upper stage to meet practically all of the DoD's Heavy-Lift requirements and most of NASA's BEO Missions. Almost like OTL Ariane 5.

A Jarvis-L rocket lifts off from Capo Passero, Italy:

The Antares-SR (Short Range) spacecraft can carry 6 astronauts into Low Earth Orbit and support them for several weeks.

(These excellent add-ons were made by Forum Orbiter Italia)

The Jarvis-M rivals the Saturn V in payload capacity.

Something I found over at Ex Astris Scientia's archives - a "filling the gaps" project concerning ST's infamous DY series of early starships :

DY series evolution from the DY-100 to the DY-500.

An idea on how the DY-300 looked like and how it was launched.

A late, heavy-haul descendant of the series, the DY-900.

The Leviathan, one of the ships from the last known series type, DY-1200.

Atlas V can fly with just one SRB. (Atlas V 411)

True. As long as the central engines can gimbal sufficiently, and the SRBs aren't too powerful relative the the central engine, the rocket can fly fine.

As another example, it doesn't appear that the SRBs on the Atlas V 551 are symmetrical either;

Not sure if you noticed, but the boosters on 8430 are not symetrical, that is not ninety degrees of each other. Rockets can be real sensitive about that sort of thing.

They don't have to be. The SRBs are pre-gimballed to fire into the LVs Centre of Mass. Just like OTL STS SMMEs, Delta II, Atlas V, and Ariane 4.

Yeah, gimballing like that prevents any resulting torques (that is, the vehicle doesn't try and spin out of control). It does make the vehicle fly a bit "sideways,' which can be interesting, but it's controlable--it just means you're generating an angle of attack and some lift/drag forces the same way a wing would. Check out these stills from the launch of an Atlas V 411 (4m fairing, 1 SRB, single engine centuar): http://www.launchphotography.com/ASTRA_1KR.html As you can see, it's moving a bit sideways as it clears the pad. However, since the thrust is through the center of mass, it remains controllable as long as the resulting flight path angle is small.
