Narrative:

I was working north radar; handling departures and arrs off anc airport and elmendorf AFB. I had a handoff to assist me who was training a developmental. We were in the midst of a large arrival rush of fighters to elmendorf. The final to elmendorf crosses just off the departure end of runway 32 at anchorage. Anchorage tower calls handoff for departure releases. Handoff was making good releases between the flts of fighters. It got dramatically more complex as the flts of fighters began requesting flight split-ups for individual PAR's. Then it got even more complex when edf gca advised they wanted 10-12 mi between aircraft on their runway 6 final. I was scrambling to split up flts and keep them at the required interval and not deviate south radar's airspace. Anc tower is very bad at 'hitting holes' on the elmendorf final with runway 32 departures. 10 mi gaps are just big enough. I had aircraft X on a 070 degree heading descending to 1600 ft on a 12 mi final to elmendorf. I saw the spacing was good with aircraft X preceding traffic; so I switched him to the gca; forgetting there was 1 crossing departure off runway 32 in front of him. Aircraft Y departed; I idented him and turned him to a 360 degree heading to get across aircraft X final sooner. I issued traffic to aircraft Y who got the fighter in sight when they were about 4 mi apart; and I instructed him to maintain visual separation. Concurrently; handoff called gca to issue traffic to aircraft X and advise him to maintain visual separation. I screwed up. I forgot the heavy departure and gave the communication change to aircraft X too soon and screwed myself. Traffic was way too fast and complex and I simply lost track of the anc departures. Handoff was training and coordinating when I communication-changed so they did not catch that. Another bad day.

Title: A11 CTLR DESCRIBED CONFLICT WITH MIL ACFT LNDG ELMENDORF AFB AND DEPARTING ANC AT 2500 FT; NO RECORDED LOSS OF SEPARATION LISTED.

Narrative: I WAS WORKING N RADAR; HANDLING DEPS AND ARRS OFF ANC ARPT AND ELMENDORF AFB. I HAD A HDOF TO ASSIST ME WHO WAS TRAINING A DEVELOPMENTAL. WE WERE IN THE MIDST OF A LARGE ARR RUSH OF FIGHTERS TO ELMENDORF. THE FINAL TO ELMENDORF CROSSES JUST OFF THE DEP END OF RWY 32 AT ANCHORAGE. ANCHORAGE TWR CALLS HDOF FOR DEP RELEASES. HDOF WAS MAKING GOOD RELEASES BTWN THE FLTS OF FIGHTERS. IT GOT DRAMATICALLY MORE COMPLEX AS THE FLTS OF FIGHTERS BEGAN REQUESTING FLT SPLIT-UPS FOR INDIVIDUAL PAR'S. THEN IT GOT EVEN MORE COMPLEX WHEN EDF GCA ADVISED THEY WANTED 10-12 MI BTWN ACFT ON THEIR RWY 6 FINAL. I WAS SCRAMBLING TO SPLIT UP FLTS AND KEEP THEM AT THE REQUIRED INTERVAL AND NOT DEVIATE S RADAR'S AIRSPACE. ANC TWR IS VERY BAD AT 'HITTING HOLES' ON THE ELMENDORF FINAL WITH RWY 32 DEPS. 10 MI GAPS ARE JUST BIG ENOUGH. I HAD ACFT X ON A 070 DEG HDG DSNDING TO 1600 FT ON A 12 MI FINAL TO ELMENDORF. I SAW THE SPACING WAS GOOD WITH ACFT X PRECEDING TFC; SO I SWITCHED HIM TO THE GCA; FORGETTING THERE WAS 1 XING DEP OFF RWY 32 IN FRONT OF HIM. ACFT Y DEPARTED; I IDENTED HIM AND TURNED HIM TO A 360 DEG HDG TO GET ACROSS ACFT X FINAL SOONER. I ISSUED TFC TO ACFT Y WHO GOT THE FIGHTER IN SIGHT WHEN THEY WERE ABOUT 4 MI APART; AND I INSTRUCTED HIM TO MAINTAIN VISUAL SEPARATION. CONCURRENTLY; HDOF CALLED GCA TO ISSUE TFC TO ACFT X AND ADVISE HIM TO MAINTAIN VISUAL SEPARATION. I SCREWED UP. I FORGOT THE HVY DEP AND GAVE THE COM CHANGE TO ACFT X TOO SOON AND SCREWED MYSELF. TFC WAS WAY TOO FAST AND COMPLEX AND I SIMPLY LOST TRACK OF THE ANC DEPS. HDOF WAS TRAINING AND COORDINATING WHEN I COM-CHANGED SO THEY DID NOT CATCH THAT. ANOTHER BAD DAY.
