Just a report on my observations
I had 4 for 4 TSAMs in recent mission launched at enemies that impacted the water while homing on - whales - that were within 50 ft of the surface.
i watched the TSAM turn off its fired course as if a target was acquired but nothing was there... so looked around as the missile went lower and lower toward the water - impacting about 50 yards short of a blue whale.
4 launches
same result 4 times on the same whale
