Preserved in the National Vigilance Park beside the NSA at Fort Meade, Maryland. This aircraft is painted to represent Bu No 144850 and is dedicated specifically to "Ranger 12", which was lost on 25 January 1987. Following an operational mission in the Mediterranean, the plane crashed off the USS Nimitz's flight deck. While the crews of other EA-3B's that crashed off aircraft carrier decks had survived the ordeal, in this case, all seven aircrew were killed.
