While past performance is no guarantee of future results, does anyone really think NASA can build and launch this in 4 years?

AFAIK, all the PPE bids currently known are heavily derived from existing commercial systems. 4 years is pushing it, but probably not by much. Construction of the pressurized modules will probably be more time consuming though

Unless they launch the PPE on a second unmanned iCPS or build a second MLP, it is not flying before mid 2023. This is driven by the MLP availability for EM-2, which is 33 months after Block 1 stops flying.

"commercial launch vehicle" means not SLS.  It could fly on Delta IV, Atlas V, Vulcan, Falcon, BFR, Blue Origin, etc.  What ever is available and certified.

No.

Yes, it is only a spacecraft

The Power and Propulsion Element of the DSG is based on the propulsion module of the ARM. How far along did the ARM get?

With regards to the propulsion module: Powerpoint stage basically.

The robotic section passed KDP-B in 2016 and an RFP for DDT&E was issued that same year for the robotic spacecraft (including the propulsion module). Proposals were due in October 2016. But no contracts were awarded because ARM was killed-off in April 2017.
So, the propulsion module is nothing but fancy CGI right now.

The companies on contract to look into DSG only have contracts for design studies and Proof-Of-Concept ground mock-ups. Which is a long way off from DDT&E activities for the actual PPE.

Pity.
