Yep, that was a CEM* for the skippers and a CLM** for all the officers on duty at the time....
*CEM - Career Ending Move

The TR had a collision one fine night with one of our accompanying cruisers (Leyte Gulf, IIRC) just before our winter '96 deployment to the Med. I came off midwatch and racked out, they started drills, including ahead-flank-to-back-emergency-full, and someone on the bridge during that evolution decided to call Leyte Gulf into close-in trailing position, about 1 mile back. Well, that became a REALLY-close-in trailing position, about contact-distance. Seems both ships' lookouts were... tired, let's say, and the phone talkers down in the Control Room said they heard a REALLY excited voice shout something about a "pop-up contact aft!" about 10 seconds beforehand. I remember being woken up by the sound of the Collision alarm, which had been leaned on by mistake by someone a few weeks prior - I thought to myself, "Okay, announce 'Disregard alarm' and let us all get back to-" and the ship shuddered. Leyte Gulf ended up with a 20-foot-long hole in her bow about 3-4 feet above the waterline, and we lost one of our aft CWIS mounts and had one of the poppet-valves for a main engine damaged - the engine I was Throttleman watchstander for our upcoming Operational Safeguards Reactor Exam, in fact, which sucked royally during said exam about a week later. Many MILLIONS of dollars of damage to both ships. Leyte Gulf had to return to port post-haste for repairs, while TR stayed out and completed our pre-Med-deployment shakedown/ORSE cruise. I looked like a chump during low-speed maneuvers during the test, since without that one valve (of 7 in the engine's steam chest), my engine went from 0-50rpm almost instantly, and at a far-different point than the other 3 engines. Fortunately, the examiners knew why that was, and we didn't get dinged for it.
I heard that both ships' OODs got letters of reprimand entered into their records, and although I never did hear what happened to Leyte Gulf's CO, ours (Capt Christenson) had been up for his first star. That went away (too bad - he was a good guy).
