Q:

Mass manufacturing of satellites

Airbus has announced a mass-manufacturing unit for OneWeb constellation of satellites. See for example Space News' With a new satellite factory in the U.S., Airbus eyes opportunities in military space 
Currently what is the state of the industry in terms of mass manufacturing of (nearly) identical spacecraft intended for constellation deployment? Are there any facilities producing for example 10 spacecraft a week? 100?
Which efforts are progressing such that there is likely to be mass-manufacturing of small satellites in the next few years?

A:

Planet Labs opened a new factory in September that can produce 40 of their Dove satellites per week. Doves are 3U CubeSats - you can read more about the Doves themselves here. Outside of Planet, OneWeb/Airbus, and SpaceX in the future, I am not familiar with anyone who has concrete plans to mass-manufacture satellites, though I have read of a number of constellation proposals from entities such as Darpa, Samsung and Boeing. There are also a few constellations proposed from the Chinese, but to my knowledge none of them are more than a few hundred satellites apiece. We’re still in very early days of constellations (and megaconstellations) even being considered practical, thanks to lower-cost launch such as the PSLV, Falcon 9, and Electron.
