According to the leak documents, the project Protego was maintained between 2014 and 2015. The Project Protego is a PIC-based missile control system that was developed by Raytheon, one of major U.S. defence contractors.
Leaked document reveled that system is installed on-board a Pratt & Whitney aircraft (PWA) equipped with missile launch systems (air-to-air and/or air-to-ground).
A missile could be launched only after the Master Processor (MP) receives three specific valid signals from a beacon (‘In Border,’ ‘Valid GPS,’ and ‘No End of Operational Period’).
All the detailed information about the projects scheme description, a guide on how to configure and build Protego images, and other related data is described on leaked documents.
Documents also detailed that, the missile system has micro-controllers for the missile itself (‘Missile Smart Switch’, MSS), the tube (‘Tube Smart Switch’, TSS) and the collar (which holds the missile before and at launch time).
