There's something very odd about the USS Fitzgerald incident

For a US Navy warship to allow itself to be very nearly destroyed by a civilian cargo ship virtually requires an epic career-ending screwup.  The exact nature of that screwup has yet to be determined, and the Navy is understandably staying very tight-lipped about it.  But they have said one thing on the record which is almost certainly false: that the collision happened at 2:30 AM local time:

But in fact the collision almost certainly took place an hour earlier, at 1:30AM, and as far as I can tell the Navy has not corrected the record.  In fact, on the 19th they doubled-down and insisted that the collision happened at 2:30.

How do we know that the collision happened at 1:30?  Because thanks to modern tracking technology we know exactly where the ACX Crystal was and when.

Here's the route around the time of the collision in more detail:

We don't know where the Fitzgerald was because military ships are not tracked in the same way that cargo ships are (for obvious reasons).  But we can tell from the track of the ACX Crystal and the photos of the damage exactly what happened.  The Crystal was en route from Nagoya to Tokyo.  Shortly before the crash she made a slight turn to port in order to navigate the straight between Toshima and Oshima islands.  Then at 1:30 she made a very sharp turn to the right.  This was (almost certainly) a result of the collision.  How do we know?  Because the Crystal was traveling at 17 knots at the time, and she could not possibly have made a turn that sharp on her own while traveling that fast.

Here's a photo of the Crystal's bow after the collision:

and the Fitzgerald:

So they must have collided like this:

The Crystal's port bow hit the Fitzgerald's starboard side abeam her bridge.  This would account for the sudden change in course: the Fitzgerald pushed the Crystal to starboard.

What happened after that is that the Crystal returned to her previous course and continued on it for half an hour.  Then she slowed down, made a U-turn and returned to the collision site.  The most plausible theory that explains all this is that the Crystal was on autopilot, and there was either no one on the bridge, or whoever was there didn't actually know how to drive the ship.  The first theory seems most plausible to me.  The Crystal's crew has gone on record claiming that they saw the Fitzgerald coming and tried to warn her of the impending collision:

A U.S. warship struck by a container vessel in Japanese waters failed to respond to warning signals or take evasive action before a collision that killed seven of its crew, according to a report of the incident by the Philippine cargo ship's captain. 
In the first detailed account from one of those directly involved, the cargo ship's captain said the ACX Crystal had signaled with flashing lights after the Fitzgerald "suddenly" steamed on to a course to cross its path. 
"The container ship steered hard to starboard (right) to avoid the warship, but hit the Fitzgerald 10 minutes later at 1:30 a.m., according to a copy of Captain Ronald Advincula's report to Japanese ship owner Dainichi Investment Corporation that was seen by Reuters."

But this does not square with the facts.  The Crystal did not change course before the collision; if she had the collision surely would have been avoided.  The Crystal does not turn on a dime, but ten minutes is more than enough to change course far enough to avoid a collision.  Furthermore, if the crew knew of the impending collision, then they surely knew of the actual collision, in which case why would they wait half an hour before turning around or even slowing down?

The only theory consistent with the Crystal's trajectory is that there was no one on the Crystal's bridge at the time.  The crew was asleep.  They were awakened by the collision.  The Crystal is enormous, and there are only twenty people on the crew.  It is easy to see how, in the darkness, it could have taken them half an hour to figure out what the hell had just happened and decide what to do about it.  It is also easy to see why the Crystal's crew would lie about this.

What is not so easy to see is why the Navy continues to insist that the collision happened at 2:30 when all of the available facts and everyone else, including the Crystal's crew and the Japanese coast guard say that it happened an  hour earlier.  Getting it wrong initially could be a mistake, but failing to correct the record over a week later makes it look like a deliberate lie.  But why would the Navy lie about this?  It makes no sense.

For what it's worth, I think the Navy's response is more likely to be inept public affairs management than deliberate lying. It looks to me like they simply don't want to change anything they're saying publicly until the internal investigation is complete.
