Military aircraft mostly use GPS and INS for navigation. Cruise missiles the same, as well as TERCOM [1], as you alluded to.

I recently spoke to old aircrew guys I worked with and apparently they stopped teaching manual celestial nav in the late 90s finally. Automated celestrial nav was, per my understanding, never too common although SR-71 aircrews commonly used its system.

It's still pretty common in space stuff. From Wikipedia ( https://en.m.wikipedia.org/wiki/Celestial_navigation):

A variation on terrestrial celestial navigation was used to help orient the Apollo spacecraft en route to and from the Moon. To this day, space missions, such as the Mars Exploration Rover use star trackers to determine the attitude of the spacecraft.
