Mode 5 is the current military Identification, Friend or Foe (IFF) transponder system used by the United States and NATO forces for identifying friendly aircraft and preventing fratricide. Developed beginning in 1995 and adopted by NATO in 2002 via STANAG 4193, Mode 5 replaced the legacy Mark XII Mode 4 system with a cryptographically secured, spread-spectrum radio-based architecture that transmits GPS position data and other identification information. The system became the exclusive IFF standard for U.S. military and NATO operations on June 30, 2020, when Mode 4 was officially decertified. Mode 5 uses advanced encryption, anti-jamming capabilities, and modern modulation techniques to provide secure aircraft identification across both airborne and ground-based interrogation platforms.

Mode 5 é o sistema de transponder Identification, Friend or Foe (IFF) militar atual utilizado pelas forças dos Estados Unidos e da OTAN para identificar aeronaves amigas e prevenir fratrícídio. Desenvolvido a partir de 1995 e adotado pela OTAN em 2002 via STANAG 4193, Mode 5 substituiu o sistema legado Mark XII Mode 4 com uma arquitetura de transmissão por rádio com espectro expandido e criptografia securizada que transmite dados de posição GPS e outras informações de identificação. O sistema tornou-se o padrão IFF exclusivo para operações militares dos EUA e da OTAN em 30 de junho de 2020, quando Mode 4 foi oficialmente descertificado. Mode 5 utiliza criptografia avançada, capacidades anti-jamming e técnicas modernas de modulação para fornecer identificação segura de aeronaves em plataformas de interrogação aeroportadas e baseadas em solo.
