In an earlier speculative discussion I had made some estimates of ship sizes from the series, some of these turned out to be wildly wrong, and others nearly on target, and in the meanwhile, in idle moments, I refined some of my earlier estimates, coming closer, but the time for speculation is past, a verified Expanse ship size chart is now here, well, at the link below.

Project Orion The USAF Plan 1962
Dr. Brent Ziarnick, Major, USAFR, gives an excellent talk on Orion and the role it might have played as part of the US strategic nuclear forces.
The engineering and physics side of nuclear pulse propulsion has been covered in great detail through declassified documents such as the General Atomics report on Orion, which can be found here: GA-5009 vol III "Nuclear Pulse Space Vehicle Study Conceptual Vehicle Design" and George Dyson's book,* which is an essential study guide to Orion, detail on the USAF side of Project Orion is still emerging. This video provides an in depth look at the scope of those plans.
