OVERVIEW OF DIANA

NATO DIANA is the Defence Innovation Accelerator for the North Atlantic, a NATO body dedicated to finding and accelerating innovation to provide decisive defence and security effects for the Alliance, while fostering deep-tech innovation.

NATO DIANA is comprised of a Board of Directors, representing all 32 nations, and an operational team referred to as the DIANA Executive (“DX”).
