Why Ada matters.

We know that the majority of code for the F-35 was likely written in C++. The software for the F-22 on the other hand,  was largely written in Ada, a sane language that’s great for real-time systems that has an extremely low rate of failure. This quote from the site Hacker News (user PeCaN) regarding the use of C++ in real-time systems sums it all up:

“Writing fault-tolerant real-time C++ is like walking on a tightrope while gripping a gun with the safety off. You can do it, but it’s not particularly pleasant.”

Ada has been used extensively over the years in many fighter jet projects: BAE Systems Harrier, Panavia Tornado, BAE Systems Hawk and Lockheed-Martin F-16 and F-22. And the Typhoon Eurofighter. They are using GNAT Pro Ada to implement and maintain the code for this jet, because of its robust systems architecture. Not C++. If I had to choose a jet, I would take the Eurofighter over the F-35 any day. Not just because the software works,but because it may actually be more maintainable over the total lifespan of the aircraft.
