Rear Admiral Meyer’s philosophy of “Build a Little, Test a Little, Learn a Lot” drove the testing and milestones of the Aegis system. Having witnessed problems with existing missile systems related to a lack of testing, tests that incorporated too many objectives, and failed system integration efforts requiring massive “get well” programs, he drove the project to conduct numerous tests in development and in delivery of production gear prior to ship installation.
That philosophy carried over into the sea-based ballistic missile defense (BMD) program, using the Aegis weapons system at its core. The following are scenes from the development of Aegis BMD — from the designing board to sea. A clear example of the results of following that philosophy may be seen in the sequence of test shots over the final two minutes of the film — the early intercepts aimed for the center of mass of the target. As the tests progressed, watch how the aim point is walked forward towards the harder to hit but more important (simulated) warhead section of the target:
