Indeed, Freedom construction is very much faster than ISS IOTL. I think this is a factor of both heavy lift (one of those huge truss segments with solar arrays in a single H03 launch!) and NASA's impressive flight rate ITTL: by my count, there were 8 launches between November 1988 and July 1989 to get to IOC (3x H03, 5x M02), not including any AARDV missions, so almost 1 per month, all from the Cape. That beats the hell out of OTL's Shuttle maximum sustained rate of around one mission every 2 months and is starting to look closer to the Soviet 'sausage-factory' launch rate (or SpaceX's flight manifest).
One thing I think Griffin got right: "If we build another station, I hope we're smart enough not to do it in 20-ton chunks again" (or words to that effect)...
Do not forget that ISS IOTL had 2 year delay unlit Russian module were delivery, then was the Columbia Disaster in 2003 what interrupt the ISS assembly for 2 years.
defacto is ISS not complet, there missing a Russian Module Nauka (aka Russian Research Module) that supposedly to be launch in December 2013.
I hope the Proton rocket work this time right
Freedom in Eyes turned skywards is not assembly piece by piece by shuttle flights, but launch the Parts by advance Saturn rockets what goes much faster
Freedom (Liberty in ver 3.0 ) in Ronald Reagan's Space Exploration Initiative, Imitative is launch by two Shuttle-C flights and 4 shuttle flights in 1992/1993
the two Shuttle-C brought the Truss and 2 Nodes in 28° Orbit, the Shuttle the Habitat and 3 lab module and Crew rescue/ resupply capsule
After finish my Technical advice for How Silent Fall the Cherry Blossoms
and the Drawing for Eyes turned skywards, I will overwork Ronald Reagan's Space Exploration Initiative completely.
