INVAP have done a number of Defense and Security developments, carried out mostly for the Argentine Armed Forces. Among these is the Campaign Data Processor (PDC) developed for the Argentine Military, that works as a portable C3 (Communication, Command and Control) room, integrating real-time data from remote sensors such as radars.
To support the navigational expertise of officers and NCOs, INVAP have also developed MELIPAL for the National Nautics School of the Argentine Navy. MELIPAL is a simulator designed to train students to pilot their ships by radar, and has a number of civilian applications.
INVAP have experience at repairing and upgrading military gear, i.e.: the sliding doors for the helicopter hangar of the Hercules Type destroyers of the Argentine Navy. This piece of equipment required a structural redesign of the whole stern sector of this combat vessel.
