Narrative: I was working the D4 when D3 called me for a point-out for Aircraft X heading westbound along the sector 3/4 boundary. I approved the point-out because his route appeared to not be a factor for my traffic at that time. Once Aircraft X approached the boundary between sectors 3/4 and HCF approach; Aircraft X took an unexpected sharp left turn southbound straight towards Aircraft Y and our string of inbounds into HNL as well as being in the middle of the departure corridor. We reached out and had Aircraft X turned out. We also turned Aircraft Y left to the southwest to avoid Aircraft X. After that Aircraft X went NORDO. After some time; Aircraft X came up on our (sector 4) frequency and wanted to descend and cancel flight following in the vicinity of JULLE right in the way of both the departure and arrival corridors to land on the ship that was apparently in that area. The R-side tried vectoring Aircraft X southeast out of the way of the traffic but Aircraft X left frequency again.My biggest recommendation to resolve this conflict from happening again is to not have the aircraft carrier stationed in the middle of our corridors.


Second narrative: There were 3 flights of [military aircraft] flying around VFR at all different altitudes; they were flying around MKK climbing and descending getting in the way of all the IFR traffic inbound and outbound of HNL. I was working Aircraft X; VFR east bound at FL215 which was no problem; then he wanted to RTB back to the ship which was parked just south of CKH VORTAC which is in HNL approach airspace and in the outbound corridor. He was flying westbound at 125 and wanted to descend low and terminate; so I did that. Then he came up again on the east side of MKK island heading westbound at 12;500 I told him to start his descent for the ship and said he wanted to stay at that altitude; so I called approach and they said to put him over the JULLE arrival which is the other sectors airspace. He just didn't want to cooperate with anybody and I think the problem is that the ship is parked right in the middle of all the departures and arrivals; and they wanted to play around during the rush going 400 knot east and west.I feel someone should have coordinated them parking the ship somewhere else.


Synopsis: HCF TRACON Controllers reported a problem with three military aircraft that were not following instructions and wanting to return to their ship which was right in the middle of the departure arrival corridor.
