Approximately $5.6bn in security assistance support for Ukraine has been announced by the US since the start of the invasion.
US President Joe Biden has approved an additional $1bn in security assistance to strengthen the abilities of the Ukrainian armed forces in their fight against the Russian invasion.
The military package is the latest tranche bound for Ukraine and includes approximately $350m from the Presidential Drawdown Authority (PDA).
This drawdown includes equipment such as 18 155mm howitzers, 36,000 rounds of 155mm ammunition, 18 tactical vehicles to tow the 155mm howitzers, more ammunition for high-mobility artillery rocket systems, and four tactical vehicles to recover equipment, and spare parts and other equipment.
These capabilities will be drawn down from existing US military stocks.
The remaining $650m in support will come from the Ukraine Security Assistance Initiative (USAI) and includes two Harpoon coastal defence systems, thousands of secure radios, thousands of night vision devices, thermal sights and other optics, and funding for training, maintenance, sustainment, transportation, and administrative costs.
