NAS Lakehurst, New Jersey

The claim: Lakehurst, 7,400

What it really is: Naval Air Engineering Station Lakehurst is the provider of full spectrum support for aircraft launch, recovery and support equipment systems for U.S. and allied Naval Aviation Forces at sea and Marine Corps Expeditionary Aviation Forces ashore.

The base was also the site of the Navy's lighter than air programs (i.e. airships, blimps) and still contains two huge hangers that once housed airships.

The base is also the site of the Hindenburg disaster.

Earle Naval Weapons Station, New Jersey

The claim: Colts Neck, 11,000

What it really is: Earle Naval Weapons Station is a Navy Base with a near 3 mile long pier that is used to load and unload ammunition from warships a safe distance away from the heavily populated areas that surround the base.

Also I imagine the site attracts a lot of site seers as well due to the fact that the base has such a huge pier.

Ft. Dix / McGuire AFB, New Jersey

The claim: Possible deportation point for detainees. Lots of pictures taken of detention compounds and posted on Internet, this camp is well-known. Facility is now complete and ready for occupancy.

What it really is: It's actually called the Joint Base McGuire-Dix-Lakehurst, which was formed in October 1, 2009 as a result of a merger of the United States Air Force's McGuire Air Force Base, the United States Army's Fort Dix and the United States Navy's Naval Air Engineering Station Lakehurst.

Despite the claims of there being numerous photos of a prison camp there, I can't find any of them. In fact satellite photos of the base doesn't show anything at all that resembles a prison or a prison camp.

Edit: Fort Dix does have a Federal prison there, but it's minimum security, and it only holds 4250 prisoners.
