The positions of aircraft carriers at sea are usually not that hard to predict, with the size of the vessels, their small number and the electronic surveillance tools available.
Today’s invention is a way for a navy to get their carriers to a new location much more rapidly than anticipated (based on estimates of the top speed of the ship). The ability to bring your aircraft to bear unpredictably on an enemy fleet provides an obvious tactical advantage.
Imagine an aircraft carrier with a docking point on its underside.
To this, a friendly nuclear submarine (which is hard to track) can attach itself, without being detected.
The dock allows the sub to add drive the surface ship, so that its speed can be greatly enhanced.
It might also allow for covert transfer of personnel or supplies.
