After delayed flight because of maintenance delay due to A check and Engine 1 replacement we departed. At approximately 100 ft I noticed the OVHT Eng 1 NAC EICAS message and at 200 ft noticed the Fire Eng 1 ECIAS message. We climbed through 400 ft and received the master warning accompanied by the Fire Warning Bell. Autopilot was engaged and we climbed through 1000 ft and I preformed the QRC for Fire Eng 1 and started our EFP and notified ATC and a Mayday aircraft. Completed QRH recall review followed by after takeoff checklist. Upon completion of the QRC checklist the Fire Eng 1 Warning disappeared so we did not need to blow the fire bottles. We asked for vectors back to [the airport] and requested the fire department standby to inspect the engine for any signs of a fire. After landing we exited runway and parked on taxiway. Fire department inspected engine and determined there was no indication of a fire and we were cleared into the maintenance ramp stand. We notified Ops enroute of the return and on the ground notified maintenance control; Ops; Dispatch; and scheduling.
A Boeing 747-400 captain reported observing #1 Engine Overheat and Fire Warning lights shortly after takeoff. The appropriate emergency checklists were completed; and a return to the departure airport was successfully accomplished.
