The availability requirement for the SKA telescopes will have a major impact on the design, capital and operating costs. The design‐for‐reliability, maintainability, maintenance planning and performance expectations should be well balanced. Engineering analysis indicates that the SKA telescopes should have an inherent availability of 99% and both telescopes are required to have an operational availability of at least 95%. This paper discusse the availability and support challenges of building and operating two telescopes in Australia and South Africa. It describes the approach to the critical design review of the system, with a special focus on simulation modeling and sensitivity analysis. It also discusses the use of failure data from the precursor telescopes and gives technical insight into the development of a digital twin for decision making.
