"I've got a buck that says this Iranian sub was in the sights of a US sub before, during, and after this launch and the Iranian skipper never knew it."
Very likely, but with the Russian rocket-torpedo they've acquired they could fire a spread of two or three and have it reach the US sub before our torpedo reaches them even if we fire first. 200 knot speed makes one hell of a difference. Also allows no time for the US sub to maneuver out of the way.
They'd never get the shot off.
