The Department of Defense announced Friday a new $775 million military assistance package for Ukraine on Friday as Russia's unprovoked invasion of the country nears the six-month mark.

Why it matters: The package includes four additional High Mobility Artillery Rocket Systems (HIMARS) 16 howitzer heavy field artillery pieces and 36,000 rounds of ammunition, 15 surveillance drones and 40 mine-resistant troop transport vehicles.

• Ukraine will also receive 50 Humvee-type vehicles, 1,000 Javelins, 2,000 anti-armor rounds, mine clearing equipment and new communications systems, according to the Defense Department.

By the numbers: It comes after the U.S. announced a $550 million military aid package for Ukraine earlier this month.

• With the new package, the Biden administration will have committed a total of $10.6 billion in security assistance to Ukraine.
• It is the Department of Defense's 19th drawdown military aid package to Ukraine since August 2021.

What they're saying: "As President Biden has made clear, we will support Ukraine as they defend their democracy for as long as it takes," the Defense Department said in a statement.

• "The United States will continue to work with its Allies and partners to provide Ukraine with key capabilities to meet Ukraine’s evolving battlefield requirements," it added.

The big picture: While Russia has made incremental territorial gains in Ukraine's Donbas region over the past months, it currently appears to be on the defensive in Kharkiv and Kherson 0blasts.

• HIMARS have allowed Ukraine to strike Russian military stockpiles, command posts and other targets far behind the front lines.
• Russia has suffered material losses in Crimea after multiple military installations were recently hit with explosions, including Saki Air Base in southwest Crimea.
• The explosions, which Ukraine has not officially claimed or denied responsibility for, carry major symbolic and strategic ramifications for Russia's hold on the peninsula, Axios' Dave Lawler reports.
• Russia also faces increased pressure from dozens of countries, the United Nations and other international organizations to remove its troops and military equipment from Ukraine's Zaporizhzhia nuclear power plant.
