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).

Seems to be standard in India as well. E.g. the newly announced made in India space microprocessor is targeted by an in house Ada compiler: https://thestateindia.com/2025/09/02/vikram-3201-india-unvei...

Thank you for sharing this! I'd love to know more about what led them to develop their own CPU, and what the instruction set looks like. It looks like AdaCore actually merged their support for VISIUMCore into upstream GCC. The slides state it features SEU detection/correction, which is pretty interesting.

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.

Would love to get me some Gripen and Sdk to play around with it....
