The success of the early Apollo program was followed up by the Apollo Applications Program which sought to use Apollo technology for a variety of projects including providing a path towards lunar colonization. One of the aspects of the program was in developing space stations and habitation modules for long voyages using the S-IVB stage of the Saturn V. In the face of increasing budget cutbacks starting in 1969 most of the projects had to be abandoned. However the concept of using S-IVB was scaled down, combined with a telescope array developed from Apollo technology, and missions for the leftover Apollo hardware after the cancellation of future lunar missions. Skylab was launched in 1973 and after a troubled start which saw the loss of one of its solar panels and micro meteoroid shield saw several successful missions which saw stays starting with 28 days with the final one lasting nearly 90 days.

The Hokulani Orbital Workshop (HOW) is BDB’s approximation of the original Skylab complete with docking space for two spacecraft and a radio telescope mount using the CADS (Common Androgynous Docking System) docking ports. It is designed for up to six crew, presumably from two different 3-man Kane CSM, but in a crunch can also house two additional crew in the airlock and docking adapter.

The Hokulani is launched on a modified Sarnus V, designated the INT-21, with the telescope unit initially mounted on top of the stack. Once you have reached your desired orbit the procedure is to undock the telescope unit, which functions as a small probe unit, and have it redock on the zenith docking port of the adapter. The CADS ports are specific to both the telescope unit and the zenith porting so that they are not easily interchangeable. The actual Skylab used a series of arms and motors to move the telescope into its operational position and lock it down.

The HOW lacks an on-board engine, unlike most space stations, and simply has several RCS thrusters for lateral and rotational control. However the radiator system in the aft also acts as a sizable monopropellent tank and you shouldn’t need to refuel for quite some time. The main station body has two rather fragile wings which face downward compared to the telescope unit’s four thinner solar panels which face upward. The purpose of this is that none of the solar panels can track the sun so regardless of the direction the station is pointing at least some of the panels will be recharging the station’s systems.

Built in the VAB in KSP version 1.3.0.
