The Army Industrial Engagement Framework (AIEF) was launched by the British Army in 2019 with the aim to develop a more effective relationship with industries throughout the procurement and development process. Since the world is rapidly changing, the military field -particularly land forces-, needs to adapt to ensure operational and strategic advantages to address threats. For instance, working closely with partners and industries, is necessary to succeed and profitable for all. The Army will be able to establish its future capability requirements, while industries will focus on the Army’s needs in its research and development programs, thus enhancing modernisation efforts.
