Since 1997, ITOPP has been designing, developing and building unique, tailor-made systems for the Defense and Security, nuclear deterrence and Energy sectors. HPP technologies make it possible to store and release very large amounts of electrical energy in extremely short pulses. They are used in a wide range of applications, including energy test benches, flash X-ray systems for material studies and lightning vulnerability testing. HPM technologies enable the remote neutralization of electronic systems, particularly for counter-drone applications.

Our teams are involved at every stage of a project, from design through to testing and installation at the customer’s site.
