Narrative:
[After takeoff] at 400 ft AGL we selected LNAV. Turned the autopilot on at 600 ft; shortly after that we got a low altitude capture; I bugged the speed up to 200 KTS and selected speed mode. We leveled off a 4;000 ft MSL and were accelerating thru 170 KTS; called for flaps 1. During flap retraction the speed started bleeding off. I heard a loud bang from the right motor at about 160 KTS. My first thought was a bird strike in the right motor. I was reaching for the throttles when the first officer pushed the throttles forward because the airspeed was 140 KTS. Then we hear 2 more; loud compressor stalls from the right motor and informed departure of what we had and wanted to return to [departure airport]. The first officer stated he did not hear the first compressor stall. Departure kept us at 4;000 ft and we returned to [departure airport]. On downwind departure asked us if we were declaring an emergency to which we stated not at this time since we did not have any further compressor stalls. I did not get an artr to return due to the short time span in trying to get the aircraft safely on the ground not knowing what was wrong with the motor.

Title: A B757 flight crew reported experiencing a compressor stall in the right engine after takeoff. They returned to departure airport at reduced power.
Narrative: [After takeoff] at 400 FT AGL we selected LNAV. Turned the autopilot on at 600 FT; shortly after that we got a low altitude capture; I bugged the speed up to 200 KTS and selected SPD mode. We leveled off a 4;000 FT MSL and were accelerating thru 170 KTS; called for flaps 1. During flap retraction the speed started bleeding off. I heard a loud bang from the right motor at about 160 KTS. My first thought was a bird strike in the right motor. I was reaching for the throttles when the First Officer pushed the throttles forward because the airspeed was 140 KTS. Then we hear 2 more; loud compressor stalls from the right motor and informed departure of what we had and wanted to return to [departure airport]. The First Officer stated he did not hear the first compressor stall. Departure kept us at 4;000 FT and we returned to [departure airport].
