So is there a list or statistic of how many DOD projects actually use Ada?

Worked in the defence industry for a few years in the 2000s. I worked on exactly one Ada project. The rest were C/C++. I presume the shift away from Ada has accelerated if anythinng.

This might be a US/EU difference. It's pretty popular in the EU still, although some of the market has been taken by various Simulink to C tools.

Every Rolls-Royce gas turbine FADEC runs ADA binaries on a custom processor [1].

It's also used extensively at Airbus. Lots of DO-178C (safety critical aerospace).

One interesting project is Saab Gripen jet fighter, whose entire software stack (other than software that is treated as "black box" firmware of certain physical components) is written in Ada, and AFAIK every sale includes complete source code and SDK to make modifications.
