Description
The 13th ISS assembly launch contained the S1 truss segment, followed by the P1 truss segment on the 14th ISS assembly launch. This is part of my project to make a Kerbal version of the ISS, balancing between the real thing, how Kerbals might do it, and keeping the parts count low.
You’d probably want to launch these on STS missions.
A stock subassembly. Built in KSP version 1.11.2.
