That's a terrific question.
These are really complicated projects to do. There's a reason why, in the last two generations that looked to use constellations and satellites, virtually every company went bankrupt. Our founder likes to say that our job here is to not go bankrupt.
There's a lot of upfront capital that needs to be put in, from a financial perspective. There are also two dimensions on the technology side. You need to be able to build satellites that are enormously capable. Also, because they're so close to the earth, you need more of them. You need to be able to build volume.
Our constellation is over 4,400 satellites in its final deployment. We got 900 up in 18 months. We have kind of cracked the code about how to build satellites quickly and with high capability. Each launch is 60 satellites, which is about a terabit of capacity. Because we are our own manufacturer and our own launch provider, we've been able to control that deployment and manage the costs. That's been a complicated exercise, but one that I think we've made really good progress on and we are happy with where we're headed.
