I've personally bought a few high res images from SAT imagery.. depends the area you want, it's around 17-20 bucks per kilometer square.. which is a lot.
Anyways, my comment was that we literrally see nothing on the picture. There's no way one can identify a hull out of those pixels...
We've had many similar satellite pictures of comparable or worse quality, so this is par for the course and not abnormal.
In this picture, what we are able to make out is seemingly two separate hull modules in the part of the drydock closest to the water, which is the way that DL had previously built destroyers in.
Correlating that, with the rumours of a new round of destroyers to be built at JN and DL, means that this blurry satellite picture is indeed useful as it is an indicator that in the next few months we should keep some attention to DL.
