Narrative:
After takeoff second engine fire loop failed. Return to base lax. Landing weight 320000 pounds. Had fire/overheat upper EICAS illuminated. Callback conversation with reporter revealed the following information: the reporter stated that one of 2 fire warning loops was previously deferred per the MEL and when the second loop alerted to an engine fire it required return to lax. The reporter said he questions the judgement of dispatching a flight with 1 engine fire warning loop deferred as inoperative.
