- **Training Systems**: Realistic simulation environment for operator proficiency

### 5. Initial Aegis BMD Integration
- **Ship Modifications**: Upgrade 5 Aegis destroyers with BMD capability
- **SM-3 Block IB Missiles**: Deploy initial inventory of 40 sea-based interceptors
- **SPY-1D Radar Integration**: Link naval sensors to C2BMC network
- **Forward Deployment**: Station BMD-capable ships in Pacific and European waters
- **Cooperative Engagement**: Data sharing with ground-based systems
