Vast's Haven-2 is a commercial space station designed to succeed the International Space Station (ISS) and enable crewed operations in LEO.

It is designed to bid for NASA’s Commercial LEO Destinations (CLD) Phase 2 program, which is expected to be awarded in mid-2026, by building on Vast's Haven-1 concept.

Vast aims to launch the first module of Haven-2, a larger version of Haven-1 offering greater habitable volume (55 m3) by 2028, and then follow this up with the build and launch of 3 additional modules over a 2-year period.
