Narrative:

We were passing 1;500 AGL when I heard a loud bang followed by a shudder of the aircraft. I initially thought a bird strike had occurred. Then the bang repeated several times accompanied by airframe vibration. We determined that it was the number one engine (N1 RPM fluctuations of +/- 15%). I elected to bring the throttle lever to idle to avoid further engine damage. Flaps and slats were retracted on schedule at approximately 3;000 ft. We declared an emergency for an engine failure and asked ATC to stand by. We ran the engine compressor stall checklist and elected to shut down the engine. I dumped approximately 55;000 pounds of fuel. We returned for a coupled auto-land ILS approach.
