This was back in the 1983 timeframe.  Wikipedia shows that the DOD had a contract from 1977 to 1983 to come up with the OS which was supposedly targeted at embedded and real-time systems. At the time there were tons of different small C-compilers used on different parts of the same project -- with the ton of licenses required for each chip and RTOS supported. https://en.wikipedia.org/wiki/Ada_(programming_language)#Standardization Softech's Ada Language system had its hooks so far into VAX/VMS 3.x that shutting down the VAX/VMS system would crash the machine with a bugcheck.  I think somewhere there was a thought of a single Ada environment and programming tools across the various operating systems. I think the government wanted to standardize the military deveopment process... which at the time used a jumble of languages, embedded systems and RTOS's from various vendors with convoluted make files tied to the development environments for each part of a military intelligence/weapons system.  A bit of a bitch to maintain -- any change to one part could keep the rest from building. After Softech... NYU (IIRC) developed what is now known as GNAT -- the Gnu NYU Ada After my DEC job I did a couple of years as a system admin along with my wife.  We were building a new piece of software and she had the target system.  Fun when the embedded C compiler 100 lines in the build script suddenly goes out of license complience and stops building for no real reason... And the sysadmin has no docs as to how this builds. At the same time the government canceled a project to build a standard military computer family (chip)  which I think was the original idea and end target for all of this.  RCA, GE and others were trying to develop this but the release of the MicroVax2 kind of took the wind out of the sails -- and the Patriot missile (IIRC) used a Raytheon built box using the uVax chip set. (Don't know if this is the board used then but it's of a similar timeframe)... https://www.computerhistory.org/collections/catalog/102757133 It was the Reagan admin and it was very different times in software with more contractors working in different locations on pieces of projects and the integration was difficult.
