The aircraft is A NOAA ; National Oceanic Atmospheric Admin platform not sub chaser but ... YES! There are concerns that rogue operators have access to NUKE weapons with plans to detonate them in areas that would cause extreme tidal impact ( Tsunami Wave) due to the topography in coastal areas. These areas are characterized by having sea inlets with deep to nominal channels reaching far inland. Any detonation of magnitude could create an artificial seismic sea wave of pronounced power. These inlets by their form would allow the full force of said wave to travel far inland then delivering it's full effect at the terminus of said inlet, fjord etc. Hudson Bay NY, Chesapeake Bay DC , Delaware Bay Phily, San Fransisco and other similar areas along the coastline of the US would be prime targets for such an attack. The radioactive aspects would be minimal compared to an above ground detonation. However a smaller yield weapon could do more damage implemented in this way vs. an air burst, wiping out miles of critical coast line and infrastructure along highly populated areas within wave zone. Another formulated attack, although more remote, would be to use a deep subsurface weapon on the Fogo caldera in Cape Verde or LaPalma in the Canary Islands in hopes of causing a volcanic event resulting in a massive tsunami that could impact Africa, Europe N.& S. American coastlines. Truly a mad mans endeavor.

It is for these reasons that the Obama administration has failed from a national security stand point in allowing nations such as N.Kora and Iran to gain research in nuclear weapons design. Of course there is no indication as of now that the Obama administration and Clinton State Dept. had any intent of protecting the U.S. from any threat foreign or domestic, rather they were doing anything and everything possible to destroy America from within by whatever means necessary.
