My bets would be that this is some classify project to test supersonic drones against US detection capabilities. Maybe some kind of hypersonic glide vehicle (HGV) like the Russia Avangard [1] missile. Hopefully this is the US themself and not Russia/China testing their HGV. Edit: DARPA tesed HGV in 2010 with the Falcon HTV-2 [2], so 11 years ago, imagine what they are up to now. If you look to this launching footage [3] in infrared, when the gliding vehicle is released, it looks like a ball. The UFO video may have inverted infrared. Also, the fact that those gliding vehicles don't need propulsion and are highly maneuverable (compared to conventional aircraft) and that it ends with a crash in the water make it very likely that this is a HGV. Edit 2: The DARPA hypersonic program is still in progress in 2021, they even double the spending [4]. And there is some info for 2020 with a program called "HSW-ab" which is highly classified [5].
