A Collision (Or Grounding) At Sea Can Ruin Your Whole Day

Last month, after the USS Fitzgerald collision with a container ship and resulting loss of life, US Navy spokesmen pointed out that such collisions are extremely rare.

I promised to explain the collision based on my own knowledge and experience, but only after the Navy investigation completes its work. Until then, any analysis would be just guesswork.

I am rethinking those assurances. I still think it best to wait until the investigation is over, but it has occurred to me that we can learn a lot from some of the prior rare examples from the 20th century. I know a bit about some of these earlier incidents.

Here are some cases:

NH 66721 Honda Point.gif

September 8, 1923 Honda Point, California

The fourteen ships of destroyer squadron 11 were steaming from San Francisco to San Diego simulating wartime operations. All fourteen ships were Clemson class destroyers less than five years old. The squadron was commanded by Captain Edward Howe Watson, an 1895 graduate of the US Naval Academy, embarked in the flagship USS Delphy. 

The flagship was responsible for navigation, the other ships of the squadron followed in Delphy's wake in a column formation at a speed of twenty knots. The flagship was fitted with a new electronic navigation device, a radio direction finder (RDF), which detected a signal from Point Arguello at the entrance to the Santa Barbara Channel. The ship's officers had no experience with RDF and distrusted its bearings.

As a result, the ship was navigating by "dead reckoning," - calculating the ship's progress along its track using rpm to estimate speed. A week earlier, Japan was hit with the Great Kanto earthquake, which devastated Tokyo and generated unusual swells and currents all across the Pacific. These swells and currents may have retarded the squadron's progress down the coast.

Shortly after 9:00 p.m., in dark and foggy weather, the navigator calculated it was time to turn to enter the Santa Barbara Channel. Delphy was actually several miles northeast of the calculated position and ran aground on the rocky shore at 20 knots. The following ships attempted to turn away, some turning to port and others turning to starboard, but seven destroyers were lost. This was the largest peacetime loss of US Navy ships. 

Captain Watson accepted full responsibility and argued against any court-martial of other officers.


1950 USS Missouri Grounding, Chesapeake Bay

On January 17, 1950, USS Missouri (BB063), the last of the Iowa class battleships to be commissioned, ran hard aground in Chesapeake Bay near Thimble Shoals light in plain view of senior Army and Navy officers quartered near Old Point Comfort. The ship ran aground during an unusually high tide, making salvage difficult. She was refloated 1 February and towed back into drydock for repairs. The incident greatly amused the press, because of President Truman's personal interest in the ship, and greatly amused Army and Air Force officers because of Navy discomfort.

The ship's commanding officer, Captain William D. Brown, had taken command on December 10th as the ship's three month period of repairs was drawing to a close. Brown, a veteran of thirty years of naval service, had a distinguished career commanding submarines and destroyers, but had never commanded such a large ship.

The investigation uncovered a number of shortcomings in shipboard organization as stipulated in U.S. Navy Regulations. The principal organizational shortcoming was the subordinate position of the ship's navigator, who lacked direct access to the ship's captain.

After the Missouri grounding, Navy Regulations were changed to stipulate that the ship's navigator, no matter how junior, would be designated as a department head.

On a personal note, in 1955 I went aboard my first naval ship on a training cruise out of Norfolk. The ship was USS Iowa (BB-61), a sister ship of Missouri.

Another personal note: when I was about to be commissioned, I was asked what job I wanted. I indicated I wanted to be navigator. In 1958, I became navigator and department head at the age of 21. After that time, I was always at least a department head at sea.
