B330 were the BA 330 and the Nautilus. Bigelow has partnered with United Launch Alliance with the goal of launching a B330 module to orbit in 2021, potentially as an addition to the International Space Station. The two companies have also proposed launching a B330 to low lunar orbit in 2022 to serve as a lunar depot. The first B330 launch was originally planned to be launched aboard an Atlas V launch vehicle, but ULA stated in October 2017 that its in-development Vulcan Centaur launch vehicle was the only launch vehicle available with the performance and fairing capacity to carry the module. BA 2100 concept module The BA 2100, or Olympus module, is a concept module that would require a heavy-lift launcher and would place in orbit the complete infrastructure of a habitat, over six times as large as the B330. , estimates put the vehicle mass between 90 and 120 metric tonnes, with a diameter of approximately . The concept model shows docking ports at both ends. First Base In June 2019, Bigelow Aerospace introduced the "First Base" concept. First Base is a lunar station module that can accommodate four people; it features four airlocks and two warehouses with solar arrays on top. Delays in launch capability As a result of delays in launch capability to transport humans to the Bigelow habitats, Bigelow "laid off some 40 of its 90 employees" in late September 2011. Bigelow had expected human launch capability by 2014 or 2015 but "the prospect of domestic crew transportation of any kind is apparently going to occur years after the first B330 could be ready. ... For both business and technical reasons, we cannot deploy a B330 without a means of transporting crew to and from our station, and the adjustment to our employment levels was necessary to reflect this reality". Bigelow Commercial Space Station The Bigelow Next-Generation Commercial Space Station is a private orbital space complex currently under development by Bigelow. The space station will include both Sundancer and B330 expandable spacecraft modules and a central docking node, propulsion, solar arrays, and attached crew capsules. Initial launch of space station components was planned for 2014, with portions of the station available for leased use as early as 2015. Bigelow has publicly shown space station design configurations with up to nine B330 modules containing of habitable space. Bigelow began to publicly refer to the initial configuration
