The U.S. Navy has no interest in wrecked naval, Marine Corps aircraft until a private citizen spends their own money to locate the wreck and attempt to salvage. Only then does the navy want to step in and say "they" still hold title and ownership to the aircraft. If the crew is listed as missing and/or remains are found then by all means let the aircraft remain where at, but if the crew was rescued/recovered then why not the private citizen salvage the aircraft? The navy has plenty examples of the types they have operated over the years in museums and when it will benefit the navy they allow recoveries of aircraft ( Lake Michigan) or make arrangements with other countries.
