If you measure the length of the sub and then compare that to RWY distance markings above it ( You need to magnify the photo ) you can see that it is between 500-800 ft in length (estimate). Which if it is a US sub (most likely) would almost guarantee that it is an OHIO as they are approx 560 ft in length and LA/Seawolf etc are approx 320-350 in length. If it's non-US you could still narrow down the suspects to a few nuclear boats based off of this length estimate.
