The upgraded jets, dubbed the F/A-18 Salmon, can achieve a speed of Mach 1.6 in the air, and “up to 4 knots per hour when heading upstream” while submerged, Kilby said.

Wait so does that mean that removing dams blocking salmon access to the beautiful rivers of the western United States has become an issue of national security?

I mean fuck those fish but that is just sad if there are a bunch of F/A-18s swimming around at the base of the dam unable to get far enough upstream to reach the defense industry buildings where they breed.
