Study tips and what to memorize
- Memorize the nine AEGIS elements and each element's primary role.
- Know the SPY signal chain: RFM → Drivers → FPA → Arrays and which are cooled by SPY SKID.
- Remember locations: where MCEs, Radar Rooms, and directors are generally sited.
- Understand the data flow: SPY SIGPRO → SPY computer → CND (CTSL) → WCS → SPY uplink to missile.
- Recall key support systems: EEFC, SPY SKID, 400 Hz converters, ORTS, ATD, CEC.
Example scenario (brief)
- SPY detects contact → MMSP produces tracks → SPY computer forwards tracks to CND (CTSL) → CND applies doctrine → WCS selects weapon and computes fire control solution → MK 15/DCC + MK 200 drive SPG-62 to illuminate target and SPY uplink sends midcourse guidance to missile.
