I did say CASPIAN was the plan - not that it would or could replace NAS.
Although there are those out there that may not agree with me, NAS is a truly excellent system. A single NAS is designed to propel a single centre - not four. We often think that we have squeezed about the last drop of blood out of the old girl an then we add even more. It just shows how excellent the original design was. The people who designed it were truly gifted.
Its also rubbish to say that the software is 30 - 40 years old. Software does not grow old. It is only replaced by something better. Hence we still have NAS cos there is nothing better.
NAS software is (mainly) written in a language called JOVIAL. JOVIAL is still used is flight management systems - C17 Skytruck to name but one 'old aircraft'.
If it aint broke don't fix it.....
