Ukraine Security Assistance Initiative or USAI is a U.S. Department of Defense-led funding program to increase Ukraine's capacity to defend itself more effectively against Russian aggression through the further training of its Armed Forces, equipment, and advisory initiatives.
[1] Included in USAI packages were training, equipment, and advising activities, in order to improve Ukraine's defensive capabilities, such as marine domain awareness, operational safety, and capacity of Ukrainian Air Force facilities, as well as its lethality, command, control, and survivability.
To counter Russian cyberattacks and misinformation, USAI also supports cyber defense and strategic communications.
By 21 July 2022, the EUCOM Control Center-Ukraine/International Donor Coordination Centre (ECCU/IDCC) a joint cell formed in March 2022 had trained 1,500 Ukrainian Armed Forces members on coalition-donated equipment.
[11] The $3 billion dispersed through the initiative in August 2022 can be used to purchase equipment, arms, and ammunition directly from U.S. defense contractors.
