The Large Ultraviolet/Optical/Infrared Surveyor (LUVOIR) is one of four mission concepts being studied by NASA for the 2020 Decadal Survey in Astronomy and Astrophysics. Enabling a mission as ambitious as LUVOIR requires an array of technologies. Critically, a systems-level approach must be taken to developing these technologies, guided by architecture studies to place each technology in the appropriate system context. Three technology systems enable the LUVOIR science objectives: the system, the system, and the system. Each of the technology systems comprise the individual technology components that must be developed and demonstrated as a system. Supporting engineering manufacturing development efforts are also identified for early risk reduction. It is important to note that the high-contrast coronagraph instrument and ultra-stable segmented telescope technology systems are tightly coupled; the performance capabilities of one system drive the requirements of the other. Similarly, the ultraviolet instrumentation technology system is loosely coupled to the other two; while the relative performance affects each system, they do not necessarily drive one another. This coupling between systems requires continuous cross-validation between the technology development paths. It is therefore critical that the technology development plan be executed in parallel with a detailed Pre-Phase A Architecture Study to provide the necessary systems-level perspective and cross-validation.
