ZHU HDOF CTLR CONCERNED WITH OBSERVED MIL PLT ACTION WITHOUT COMPLETE AND COORDINATED CHANGES IN IFR CLRNC WHILE OPERATING IN THE GULF OF MEXICO.

Narrative

SHORTLY AFTER ASSUMING THE D-SIDE NON RADAR POS AT THE ZHU OCEANIC SECTOR #72; #79 AND #28 COMBINED; I WAS ALERTED BY THE RADAR CTLR THAT MIL X (AN F18 FROM RND TO NQX VIA MINOW INTXN) HAD DSNDED WITHOUT A CLRNC FROM FL410 TO FL270. THE PLT HAD BEEN ADVISED RADAR SVC TERMINATED AND ISSUED A COM CHANGE TO CONTACT ZMA OVER MINOW INTXN ON 133.9. MIL X WAS ON AN IFR FLT PLAN AND HAD BEEN COORDINATED AS NON RADAR ESTIMATING MINOW AT XP18Z AT FL410. AS I WAS COORDINATING INFO OF FLT PLANS; I DID NOT HEAR THE ACTUAL RADIO COM BTWN THE RADAR CTLR AND THE PLT. I WAS JUST ADVISED OF THE ILLEGAL ALT CHANGE AND ASKED ABOUT NON RADAR TFC. ON THIS GIVEN DAY; WE WERE RECEIVING RADAR DATA FROM TINDELL AND THAT IS WHY THE RADAR CTLR WAS ABLE TO SEE THE ALT CHANGE. BEING EXTREMELY BUSY; I ONLY LOOKED FOR TFC AT FL270 AND COORDINATED THE NEW ALT WITH MIAMI AFTER I DEEMED IT SAFE. THE AREA WHERE ACFT WAS IS NOT CERTIFIED FOR RADAR SEPARATION AND BECAUSE OF THIS; SEPARATION COULD NOT HAVE BEEN LEGALLY MAINTAINED WITH ENRTE NON RADAR ACFT DURING THE DSCNT. THIS WAS A PLTDEV BY A MIL ACFT. WORKING THE OCEANIC SECTOR WITH THE NUMEROUS WARNINGS AREAS AND DEALING WITH THE MIL; I DID NOT FIND THIS ACTION AS UNCOMMON. AS I STARTED MY CAREER AT ZDV; I CAN HONESTY SAY THAT THE OVERALL DISREGARD FOR RULES BY MIL PLTS WITHIN ZHU AIRSPACE IS MARKEDLY MORE COMMON HERE. I CANNOT ANSWER WHY I HAVE MORE PROBS WITH THE MIL PLTS HERE THAN I DID AT ZDV; BUT I SPEAK OF THIS WITH 5 YRS EXPERIENCE HERE AT HOUSTON AND APPROX 5 YRS AT DENVER. THE ONLY CORRECTION TO THIS PROB WOULD COME FROM THE MIL MAYBE REALIZING THAT THE GULF OF MEXICO IS EXTREMELY BUSY COMPARED TO EVEN A COUPLE OF YRS AGO AND TREATING THE AIRSPACE WITH A LITTLE RESPECT RATHER THAN THE PLAYGROUND IT MAY HAVE BEEN YRS AGO.
