Object
USS Enterprise-D Deflector Shields
Standard Federation starship defensive system, distinct from alien sensor-blocking technologies. Operated by the Enterprise crew to absorb physical/energy attacks, not for sensor disruption.
7 appearances
Purpose
Protect the Enterprise from enemy weapons fire, energy pulses, and space hazards during combat and high-speed maneuvers
Significance
Shields dictate survival in the three-way race to Tin Man, forcing Riker to gamble on repairs amid Romulan assaults and supernova threats; their failure amplifies crew fractures, elevates Tam Elbrun's role, and turns first contact into brinkmanship
