Like C, it's been around forever and is considered battle-proven and figured-out. Unlike C it has real-time features and a type system that isn't trying to kill you.
Also the syntax is designed to be as easy to understand as possible, typing out every word and using no three-letter abbreviations.
It's in general a language that was way ahead of its time, but survived because the DoD mandated it. Its main competitor is C, but that's mostly because the amount of engineers who know Ada out of school is really low, which is a shame, I think. Rust is way too new and Haskell has GC.
