00:00
you've been asked to meet. Thank you, Mr. Chairman.
00:03
Thank you, Senator King. Senator Rounds.
00:07
Thank you, Mr. Chairman. First, let me just say thank you to all three of you for your service to our country.
00:13
Secretary Mink, I know that you're drinking out of a fire hose right now,
00:17
so I'm not going to get into all of the current situation with regard to the Air Force.
00:22
But I would like to discuss something that I think is critical, and I know that you've got a background in it,
00:26
and that is, and it'll come to no surprise to the rest of the committee,
00:29
I want to talk about Spectrum for just a minute.
00:32
We've heard from, I know, no surprise, right?
00:36
We've now heard from 24 senior DOD officials in hearings over the last two years,
00:40
including every service chief and eight combatant commanders,
00:44
that vacating the 3.1 to 3.45 gigahertz band of the Spectrum
00:49
would have extremely serious and negative consequences for our warfighting capabilities.
00:54
In fact, the Department of the Navy alone has estimated that relocating their systems
00:58
to a different part of the Spectrum band would cost them approximately $250 billion.
01:07
How would forcing the Air Force to vacate the 3.1 to 3.45 gigahertz
01:13
and other critical bands of the electromagnetic spectrum
01:16
impact the service's warfighting capabilities?
01:20
First off, Senator, thank you for the support on this particular issue.
01:27
As you mentioned, we've been discussing this for quite some time.
01:31
And for other members of the committee and other parts of Congress and support in this area,
01:37
one of the things we'd discuss a little bit is what would it cost to do that
01:41
and what would be the impact?
01:43
I think that one of the things we're struggling with a little bit is that
01:47
just due to the nature of physics of how these systems operate
01:51
and how the atmosphere absorbs energy, that's a pretty special band.
01:56
And it's difficult and maybe in some ways almost impossible just to move to other bands.
02:02
So in some cases, it may be very difficult, if not impossible,
02:08
to totally replicate some of the capabilities we have in that band.
02:12
And it would take quite some time to do so even if we could.
02:15
So I think that's what we're struggling with now, Senator,
02:17
is how do we do that analysis to figure out what we could do
02:20
and how we would move and what spectrum we'd move to.
02:22
So it's difficult to quantify.
02:24
Our near-peer adversaries know that, don't they?
02:27
Oh, of course, Senator.
02:28
And the impacts would be pretty significant.
02:29
They would love to see us voluntarily abandon that particular part of the spectrum
02:34
from what we use it for, which is radar.
02:37
Fair to say?
02:38
I would agree with that, Senator.
02:40
It would be an unforced error for us to ever give up that part of the spectrum
02:44
for one of its highest rated uses.
02:47
The physics involved in it means that this is the place where radar really works.
02:51
Without a much better transition plan and understanding of how we would do that,
02:56
it would be a mistake, Senator.
03:01
Do you have any kind of an estimate as to what it would cost if we could migrate someplace else
03:06
even if it would not provide us as good of capabilities?
03:09
Any idea yet at all?
03:11
I think we actually had this discussion last night.
03:14
I actually don't think just because of that we don't have a coherent plan of where
03:19
and how we would maneuver or move, we actually don't have a good number for you, Senator.
03:25
General Salzman, based on what you know, the potential paths forward for building out
03:34
President Trump's Golden Dome, is it possible to make it work if the Department of Defense
03:40
were forced to vacate portions of the 3.1 to 3.45 GHz band and other unnamed critical bands
03:48
of the spectrum that the Space Force currently uses as well?
03:53
Senator, as we evaluate the sensors that are going to be necessary to pick up hypersonics,
03:58
to pick up cruise missiles, to pick up ballistic missiles, the radars are essential in that area.
04:05
And that 3.1 to 3.45 is, as the Secretary mentioned, the physical properties of that spectrum range are ideal for that kind
04:13
of detection using radar, and so the sensing part of the Golden Dome would suffer if we had to vacate.
04:19
This is a tiered system.
04:20
It's not one which is totally space-based.
04:22
There are certain assets in space that will help us to detect incoming weapon systems,
04:26
but it is critical that it is tiered with other systems that are based on the terrain
04:34
and in the area of the targets that we're protecting, correct?
04:37
Most of our space domain awareness, which is what's required to close that kill chain
04:41
as things transit through space, most of those sensors are ground-based.
04:46
The system that we're building, the dark system, lives in this particular spectrum band as well
04:51
and is critical to space domain awareness.
04:54
I'm just going to very, very quickly.
04:56
General Alvin, we're contracted right now for 100 B-21s.
05:00
Anywhere close to the number that we're going to need?
05:04
Senator, if we could snap our fingers right now, I'd take as many as we could get right now.
05:10
So as we look to the path of how many we get into the future and we look at opportunities,
05:14
we also need to look at what this B-52 modernization program, if it goes worse than we hope,
05:20
then we would need more, if it goes better than we hope.
05:23
I would say right now I'll take all I can get with the funding, but it's an incredible capability
05:27
that turns out right now it's testing pretty well.
05:30
So the 100 minimum is certainly something we can stand behind.
05:33
When we look at what the maximum is, I really want to look at the risk over time and opportunities over time.
05:37
Thank you, Mr. Chairman.
05:40
And thank you, Senator Peters.
05:42
You're recognized.
05:43
Thank you, Mr.
