I am no expert on this, but from talking to people in the aviation industry I noticed slow a trend away from the cockpit-with-2,000 controls and towards using computer screens which switch between display multiple things. Or rather, there still are 2,000 controls, but thanks to the computer-screens, the number hasn't blown up to 200,000.
So my guess is the touchscreens in these ships replaced some computer screen where input (and mode switching) had been done by physical buttons. And now they are moving it back.
OTOH controls that you normally, and especially in a critical situation, reach and operate without looking, is a different thing. They should be stationary, and provide good tactile feedback.
For planes that means that controls required during normal flight can be touch controls. After all on Concord and TU-144 pilots didn’t even have visual. However during departure and landing, pilots need physics buttons and switches as it is visual flight.
Another conclusion is that fighter jets can’t have any touch controls, they are supposed to be in visual all the time.
No touchscreens for in-flight, though, although iPads became common as replacement for paper charts.
