Based on the footnote I'm fairly certain it was Ellemtel, a joint venture between Ericsson and Televerket (the Swedish national telecom before it was privatised), and the project was AXE-N:

The AXE-N venture was to be the most expensive industrial project in Sweden after Saab’s JAS fighter. One calculation estimates that it cost Ericsson SEK 10 billion. The project has often been described as a total failure.

Swedish wikipedia has more information: https://sv.wikipedia.org/wiki/AXE-N

Some people here might know Ellemtel from their C++ style guide, which was a byproduct of the AXE-N project. In Emacs "ellemtel" is one of the built in choices for CC Mode style.
