1) Unmanned Orion to LEO on FH or Vulcan or NG.2) Crew to LEO on crew vehicle. 3) 45t OTV launched on NG.I prefer Vulcan over FH as long term it could support crewed launches of Orion. There are advantages to separate crew launch as its life support can be used in stead of Orions while waiting for OTV. Alternative is have crew waiting at ISS for OTV, giving long time window for launch delays of OTV.NB OTV+ Orion has DV of 4km/s and can deliver Orion direct to Gateway.
This is the kind of stuff I am talking about: hard pricing on the actual cost of Falcon Heavy for a NASA mission....If base cost on FH is $90M then the bump is $27M. Factor in relatively the same cost increase for full expendable or center core expendable from the $95M to $150M that was tweeted by EM.
The total cost for NASA to launch PACE is approximately $80.4 million, which includes the launch service and other mission related costs.
In an old thread about improving New Glenn's performance (specifically, this post), it was pointed out that an expendable New Glenn with 8x GEM-63s would be comparable in performance to SLS block 1. While it wouldn't be nearly as cheap or efficient as other LV options, it would still be much cheaper than SLS, could likely be developed relatively quickly and easily, and doesn't affect the overall program architecture too much, all of which makes this interesting to me as an interim Orion LV.
In terms of cost:0) Orion/SLS: $1500M Orion + charitably $1500M SLS = $3000M.1) Frankenrocket: $1500M Orion + ~$200M ICPS + $150M FHE = $1850M + huge, unquantifiable NRE2) Orion/Vulcan and FHE: $1500M Orion + SWAG $250M Vulcan N62 + $150M FHE = $1900M, modest NRE3) Orion/FH3R and FHE: $1500M Orion + $90M FH3R + $150M FHE = $1740M, medium NRE.4) Orion/FHE and D4H: $1500M Orion + $150M FHE + ~$450M D4H = $2100M, medium NRE.5) Minimal Starship + D2/F9: $200M Starship crew module + 7*$50M Starship launches + $170M D2/F9 = $720M, unquantifiable-but-likely-100%-SpaceX-funded NRE. (Don't like $50M/Starship launch? Pick a number...)6) Orion/Vulcan and New Glenn transfer stage: $1500 Orion + SWAG $250M Vulcan N62 + $100M New Glenn + $50M NG Stage 3 = $1900M. Modest NRE.Update: Added option #6

Modest NRE.Update: Added option #6Sorry, but you're SWAGing a lot more than just the Starship number here. The SLS figure you're using was the differential of the entire yearly program plus one launch with the cost of a Delta IV subtracted out, and even doing the very crude costing method of divvying up the Orion Production and Operations contract by number of spacecraft ordered gets you nowhere near $1.5B per Orion.
