A research strand rather than a teaching one. These posts track how machine learning is actually being applied in aerospace and defence: anomaly detection on flight and trajectory data, autonomous systems, sensor fusion, and the procurement and policy decisions that decide which of it gets built.
They are the most heavily sourced posts on this site and they should be read that way. Each one cites its primary sources, and claims about a specific programme, contract or capability are attributed rather than asserted. Research here is AI-assisted and then checked against the sources named in each piece.
This section exists because the engineering problems in it are unusually good teaching material: they are real, they are constrained, and the cost of a wrong answer is legible.
