The US military has delivered two AN/TPQ-36 counter battery radar systems to the Ukrainian armed forces.
The systems were delivered in response to Ukraine's request to help bolster the country's defence and internal security operations.
According to the US Army, the radar systems are expected to help Ukrainian military personnel and civilians against lethal threats, including rocket and artillery attacks.
The delivery follows President Barack Obama's delegation of authority to the Secretary of State to draw down up to $20m in defense articles and services.
Since 2014, the US has given more than $265m in security assistance to Ukraine to help deal with the ongoing crisis, which the United Nations claims has killed more than 8,000 people.
The US 2016 defence budget also commits $300m towards Ukraine to help the country enhance its defence capacity.
In September, Canadian Armed Force (CAF) personnel arrived in Ukraine to provide military training and capacity building to Ukrainian soldiers at the International Security and Peacekeeping Centre in Yavoriv.
