The plane shows up in a couple of 1956 photos taken in Iwakuni, Japan at this VP-6 squadron page; but the nose number doesn't match, nor do the colors, so clearly we're dealing with a different squadron and timeframe.
This Neptune was originally built as a P2V-5, and later modified to the "F" configuration with the addition of the two J34 turbojet engines.
Since the inlet doors on the J34s are open and the gear is in transit, I presume that this is a take-off shot.
If there are any Neptune experts in the house, please share any knowledge you might have on this airframe!
