The U.S. Department of Defense announced a new $125 million package for Ukraine's Security Assistance Initiative that includes training, equipment and advisory efforts to help Ukraine's forces preserve the country's territorial integrity, secure its borders, and improve interoperability with NATO.

"The USAI package includes two additional armed Mark VI patrol boats to enhance Ukraine's capacity to patrol and defend its territorial waters. To date, the U.S. has committed a total of eight Mark VI patrol boats," the Defense Department said in a press release on Monday.

The Pentagon said that this action reaffirms the U.S. commitment to providing defensive lethal weapons to enable Ukraine to more effectively defend itself against Russian aggression.

"The package also includes capabilities to enhance the lethality, command and control, and situational awareness of Ukraine's forces through the provision of additional counter-artillery radars and tactical equipment; continued support for a satellite imagery and analysis capability; and equipment to support military medical treatment and combat evacuation procedures," the department said.

The Pentagon also said that the remaining $150 million in fiscal year 2021 USAI funds appropriated by Congress will be provided when the Defence Department, in coordination with the Department of State certifies that Ukraine has made sufficient progress on key defense reforms this year, as required by the National Defense Authorization Act.

"The Department encourages Ukraine to continue to enact reforms that strengthen civilian control of the military, promote increased transparency and accountability in defense industry and procurement, and modernize its defense sector in other key areas in line with NATO principles and standards," the Defense Department said.

Since 2014, the United States has committed more than $2 billion in security assistance to Ukraine.
