Add is used in a lot of areas outside Defense and Aerospace (which I assume is what people associate Ada with). Air Traffic Management and Rail Signalling systems are probably the two biggest fields outside of Defense/Aerospace where Ada has commercial success. A big barrier to entry was previously the high cost of the toolchain for commercial applications (that's somewhat changed). Which meant it was only economically feasible for large companies in very safety-critical contexts.
