That is the site in Moorestown, New Jersey where the Navy tests the radars for its Aegiscombatsystem, the most capable air- and missile-defense system in the world.
All the legal constraints that had prevented use of sea-based systems in missile defense schemes disappeared, and engineers could begin thinking about exploiting the full operational potential of the Aegiscombatsystem.
The Navy built two classes of warships around the Aegiscombatsystem, beginning with the Ticonderoga class of cruisers in the 1980s and then the Arleigh Burke class of destroyers in the 1990s.
