In December 2022, the US administration announced a $1.85 billion security assistance package for Ukraine, including one Patriot air defense system. That commitment was followed by another one made by Germany earlier this month.
"RTX [Raytheon Technologies] shall provide TA to consist of advice and assistance in the planning, operation, maintenance, repair, and sustainment of the Ukraine Air Defense PATRIOT Weapon System, associated equipment and logistics support elements," the posting read.
The US Department of Defense intends to receive a commercial offer only from Raytheon Technologies, which manufactures the weapon system, but other companies are encouraged to contact the defense firm for subcontracting opportunities.
