 Thunder Cloud is the continuation of an experimentation thread that USERAF has been working for a couple of months. In this case, for Thunder Cloud, USERAF will be using high-altitude balloons as the sensor. High-altitude balloons are not tethered, so they have some station keeping that is available to them in the stratosphere, but that's the sensor that we're using. Information that the balloons will collect will relay the information down to the unit on the ground. In this case, it's the 41st Field Artillery Brigade, to which they will use the data that we provided them and use their long-range precision fires to engage the target. So, Thunder Cloud is important because it does two primary things. Number one, it assists the Army in its modernization strategy. In this part of Thunder Cloud specifically, we are looking to operationalize the stratosphere. The stratosphere is an area that the Army and other services are working to operationalize, and this is just our contribution to those modernization efforts. So, Thunder Cloud gives us, especially operating up here in the high north, it gives us a great opportunity to exercise with our allies and partners and sister services as well as we move into the future using this new technology and this new formation and this new method of warfighting.
