Lost 200 but launched 345, almost all of which are the latest upgraded version. The satellites are designed to last 5 years (the lifetime is limited by propellant because of atmospheric drag at their low altitude) and the first batches were launched 4 years ago now. As the constellation matures they will be de-orbiting satellites about as fast as they launch them.<p>Seems to me like the long term viability of Starlink (if it's not already profitable) will be assured if Starship meets its goals. They'll be able to launch way more satellites at once, for less per launch, and with faster turnaround.
