ITOPP Leader in Pulsed Power Systems
For nearly 30 years, ITOPP has provided end-to-end solutions—from design and development to manufacturing, testing, and operation—supporting critical applications in Defence & Security, Nuclear Deterrence and Energy.
With decades of collaboration alongside demanding partners, ITOPP has developed deep expertise and outstanding technical know-how in both pulsed power systems and high power microwaves. This unique experience allows ITOPP to deliver innovative, tailor-made solutions that meet the specific requirements of each client.
ITOPP is a subsidiary of the ALCEN Group and is certified to ISO 9001, ISO 14001, and ISO 45001 quality standards.
It is with immense pride that I lead the ITOPP team. From our home in the heart of France’s Lot region, we do something unique in Europe: “we manufacture lightning”. For nearly 30 years, our core mission has been to push the boundaries of physics for strategic defense and research.
Our mastery of Pulsed Power technology—compressing colossal energy and releasing it in mere nanoseconds—is a cornerstone of sovereignty for France and our allies. This expertise earns us the trust of the most demanding partners, from the CEA and DGA to the UK’s AWE, on missions where failure is not an option.
Yet, beyond this technological prowess, our true strength is our people. I have been profoundly impressed by their resilience, intelligence, and unwavering commitment. We operate by a golden rule: we never let a client down. Their success is our greatest pride.
Today, ITOPP is entering a new industrial dimension. We are channeling our expertise into disruptive innovations like our Skypulser counter-drone system, building the non-kinetic shield of the future. We are an agile company with the strike force of ALCEN a major group, ready to guarantee our security for the next thirty years.
