For over 190 years, RUSI has provided an invaluable service to the public, government and armed forces as a unique interface between the three. Today, RUSI's work is just as vital as ever, and so is your support, whether you are a corporate, foundation or individual.
As a registered charity (No. 210639), RUSI does not receive core funding from any government or institution: we are a purely independent body. However, free thinking doesn't come free, and we work hard to generate the necessary funds through membership fees, income from research projects, and the generous support of companies and individuals who believe in the importance of our work.
Contributions to our General Fund go towards the maintenance of RUSI's prestigious headquarters and the development of our core work - finding new ways to foster and facilitate defence and security thinking worldwide.
Become a member, donate or support us in another way to help us continue to build a safer UK and a more secure, equitable and stable world.
