Those old Phrog airframes are gettin tired. Osprey is sposed to take their place, but I don't know when or even if. but know at least one squadron is flying Ospreys already. Way back when, the 46s had a bad habit of aft pylon failures--as in separating from the rest of the airframe--thankfully that got fixed.
HMM 364 (Purple Fox) was with us at MMAF and there was another 46 squadron further down the flight line but it's just been too long to remember which it was.
Last time I looked there was only one 46 squadron left on the west cost, HMM 163, the rest are now VMM I don't know how long it will stay HMM I will miss the old birds but it is time for a new airframe.
