Narrative:

While established on and cleared for the rvav (rnp) Z rwy 24R at guam we receive a very sudden and fast yellow TA traffic alert then about a second later got the red RA alert. The first officer and I both looked to our right after the yellow TA and there was a military bomber heading right for us. The yellow TA box showed 2200 feet. We were approximately 2500 feet inside wabox intersection.after visually acquiring the bomber first and a second later getting the red RA with 'climb climb'; I disconnected the autopilot and started an aggressive climb. After about 200-300 feet the RA stopped. We were clear of traffic. I was stabilized a good distance out and was able to safely descend and reacquire a 3 degree glideslope with the PAPI-left lights insight and make a normal landing rwy 24R. During the last part of our approach agana tower offered us the phone number of the approach control facility located below the tower. The first officer copied it down on taxi in.first officer and I remember hearing approach control clearing an aircraft for what I believe was an 'overhead break'. I think the bomber came as close as 200 ft and one quarter (1/4) to one third (1/3) mile from us in a very high speed climb. The bomber could have been closing on us at 250-300 knots.
