The eight arms sales agreements announced Wednesday cover 82 high-mobility artillery rocket systems, or HIMARS, and 420 Army Tactical Missile Systems, or ATACMS — similar to what the U.S. had been providing Ukraine during the Biden administration to defend itself from Russia — worth more than $4 billion. They also include 60 self-propelled howitzer systems and related equipment worth more than $4 billion and drones valued at more than $1 billion.
