1. The second effort part of the Production and Deployment (P&D) phase as defined and established by DoDI 5000.02 after Low-Rate Initial Production (LRIP) and following a successful Full-Rate Production Decision Review (FRPDR). The system is produced at rate production and deployed to the field or fleet. This phase overlaps the Operations and Support (O&S) phase since fielded systems are operated and supported (sustained) while Full-Rate Production (FRP) is ongoing. 2. The production level contracted for once the production process has been stabilized. Ideally, it would coincide with the Economic Production Rate (EPR).
