Occultic government / military, projects / acronyms

I've noticed MANY of these over the years, and tonight when going over DARPA.mil 'solicitations' I noticed a new one, "ISIS". It's been a while since I've even thought about this, but it seems we should all have a detailed thread containing all of the countless occultic acronyms.

ISIS stands for "Integrated Sensor is Structure (ISIS)". It's a new DARPA project.

I know that NASA alone has too many to even begin to count, and I'm hoping to get some help in remembering them and the rest...
