During her opening remarks, Senator Collins said:

 

One final point on Ukraine, about which I shared the Chairman's commitment.  It is critical that the Administration provide Ukraine with what it needs in time to defend and take back its sovereign territory.  We expect the Administration not to wait until the 11th hour if the Ukrainians need more before the end of the fiscal year.

 

Senator Collins continued during Q&A:

 

In January, the Department [of Defense] announced that 31 Abrams tanks would be delivered to Ukraine.  The latest information I have is that that will not occur until this fall.  Is that accurate?   Could you update us on what the current delivery schedule is and whether there's any way to accelerate the delivery of these tanks to Ukraine?

 

Secretary Austin:

 

We are doing everything possible to accelerate the delivery of these tanks, and early fall is a projection.  In the meantime, we've moved a number of tanks over into theater so that the Ukrainians can begin training on this capability.  And by the time they complete that training, the tanks will be available for them to use.  We're putting in the infrastructure to be able to sustain and support this capability as well.  As you know, this is a different capability, turbine engine, and a number of pretty sophisticated systems.  But we're moving as fast as possible to get the capability in the hands of the Ukrainians, and I will certainly have that available by early fall.
