They would have known where it hit. Then the essential parts would have sank like a rock. They would have been exposed to measurable currents for a known time.

On the bottom I suspect they were lucky and didn't have strong currents, at least not strong enough to move them far or screw up the recovery vehicle. I think this is one that was easy, not like the subs where their exact locations weren't known.

I believe these were the satellites which were the subject of "The Falcon and the Snowman". It's of never-ending interest to me that through the actions of these guys, Walker, Alderich, Hanssen, et al., and guys from the other side that there weren't many secrets. It's all a game which comes out a tie.

The victories we trumpeted, such as the tunnel into East Berlin which was known to the Soviets even as it was being dug, or the tunnel under the Soviet Embassy which Hanssen gave up early on, were not victories. I'm not sure about the Northern submarine cable expeditions.

And then the Russian bug in the Oval office was precious.
