Certainly, the most upto date Phase (and Multiple) Array Radars are I think
made by Siemens Plessey Defense Systems, and they write the code in Ada.

Also the 200+ seat NERC project is written in Ada.

Etc etc etc.  

What Ada is good at is large decentralised systems like this as they involve
reuse of common components.
