The US government is reportedly preparing a new package of weapons supplies for Ukraine worth $1 billion.

The package, one of the largest so far, will include munitions for long-range weapons and armored medical transport vehicles, according to Reuters.

The package is projected to be announced as early as Monday and would add to the approximately $8.8 billion packages of weapon supplies provided by the US to Ukraine since February 24.

The next weapons package had yet to be signed by President Joe Biden, according to the report.

If signed in its current form, the package would be worth $1 billion and include High Mobility Artillery Rocket Systems (HIMARS) munitions, National Advanced Surface-to-Air Missile Systems (NASAMS) surface-to-air missile system ammunition, and up to 50 M113 armored medical transports.

It is worth noting that the Pentagon announced a separate security assistance package for Ukraine worth up to $550 million last Monday, which included additional ammunition for HIMARS.

So far, the US has sent 16 HIMARS to Ukraine and pledged to send two NASAMS on July 1.

The new massive arms transfer comes on the heels of a Pentagon decision to allow US military personnel to treat wounded Ukrainian troops at a large US-run hospital in western Germany.
