The Defence Operational Training Capability (Air) (DOTC(A)) Programme is the MOD’s solution to the future of Air centric collective synthetic training. The DOTC(A) Programme aims to establish a series of networked synthetic mission training facilities to support the development and sustainment of the UK’s Defence Capability. The DOTC(A) Core System and Service (DCS&S) Project will support the DOTC(A) Programme and enable distributed training by providing a common synthetic environment and a range of training delivery services, which will ensure coherence and interoperability across the DOTC(A) Programme.
