The Patriot missile training for Ukrainian troops at Fort Sill, Oklahoma, is wrapping up soon, an Army spokesman said Tuesday.

Sixty-five Ukrainian soldiers have been training at Fort Sill since mid-January in an expedited training cycle on using the Patriots -- training that typically can last up to a year.

The Ukrainians will depart the Army post in the coming days for Europe, where they will receive additional training, before heading back to Ukraine "in the coming weeks," Col. Marty O’Donnell of U.S. Army Europe/Africa told ABC News.

"In Europe, the Ukrainians training here will meet up with Ukrainians training in Europe, and with U.S., German, and Dutch equipment donations to validate the systems and ensure interoperability," O'Donnell said.

The United States is going to speed up the manufacture and delivery of the 31 Abrams tanks President Joe Biden approved sending to Ukraine, a U.S. official confirmed Tuesday.

Instead of making new tanks from scratch, the Department of Defense will now refurbish the hulls of several older models that will be equipped with more modern equipment, according to the official.

The new delivery target date is fall 2023, the official said; previously the anticipated delivery time was believed to be mid-2024.

National Security Council spokesperson John Kirby hinted at the accelerated timeline on Tuesday.

"We're working on that," Kirby said on MSNBC. "There's some changes that you can make to the process to sort of speed that up."

Japanese Prime Minister Fumio Kishida visited Ukraine on Tuesday for the first time since the start of Russia's invasion.

In Kyiv, Kishida laid a wreath at the memorial for fallen Ukrainian soldiers. In Bucha, where Ukrainian officials said more than 400 civilians were killed last year by Russian forces, he laid a wreath outside a church before observing a moment of silence and bowing.

"The world was astonished to see innocent civilians in Bucha killed one year ago," Kishida said. "I really feel great anger for all the atrocious acts."

Ukrainian forces destroyed Russian Kalibr-NK cruise missiles in a drone strike in Crimea as the weapons were being transported by rail, the Ukrainian Main Intelligence Directorate said on their official Telegram channel Monday.

Sergey Aksyonov, an adviser to the head of the Republic of Crimea, which Russia annexed in 2014, confirmed a drone attack on his official Telegram channel.

Debris from the aerial object damaged a household and a shop and one person was injured from the explosions, Aksyonov said.

The U.S. will announce another assistance package for Ukraine on Friday, White House spokesperson John Kirby announced Thursday afternoon, but did not detail the exact size of this next round of support.

"You'll see us tomorrow, just unilaterally, the U.S. will have another round of assistance for Ukraine coming tomorrow. And it will include mostly ammunitions and munitions that the Ukrainians will need for the systems that they already have, like the HIMARS and the artillery."

The new aid comes as President Joe Biden meets with German Chancellor Olaf Scholz at the White House Friday to discuss ongoing support for Ukraine as Russia's invasion continues.

Kirby said the leaders would discuss the "kinds of capabilities that Ukraine continues to need in the weeks and months ahead."

He also said this will be a "true working visit" between Biden and Scholz and they are expected to discuss "recent engagements with Ukrainian officials, including the President's trip to Kyiv and meeting with President Zelenskyy, as well as Chancellor Schultz’s meeting with President Zelensky in Paris last month."
