How should layered mission architecture be read?

Layered mission architecture looks beyond a single platform and considers which altitude, infrastructure and support touchpoints a system needs throughout the mission.

At the upper layers, communication, positioning and mission awareness become prominent; at field level, testing, maintenance-repair, integration and technical support become more decisive.

In the E63 approach, this reading is combined with traceable process discipline, controlled verification and supportable design from production through post-delivery operation.
