This episode is surprisingly well done. There is a brief history of the evolution of the destroyer, followed by a description of the design of the new (and most numerous) destroyer class, the Fletchers. It's candid and honest, not rah-rah either. The Japanese had already fielded the Fubuki class, larger and better armed than anything the USN had until the advent of the Fletchers in early 1943.
There are few graphics and no CGIs. The program consists of newsreel footage supplemented by good-natured crew and officers who'd served aboard them. They're frank but forgiving about the inconveniences that are seldom mention in documentaries. There was a special toilet seat for men suspected of having STDs. Four men would squeeze into a single shower at the same time. The toilets were inadequate. The cooking varied a good deal but was consistent enough in content to be boring after a time. (Nobody mentions chipped beef on toast, or SOS.)
The talking heads are frank. "The captain waited and waited -- and he waited too long, I guess," said one officer of a DD that was sunk by Japanese aircraft. On another ship, sunk at Leyte Gulf, a crewman says of his heroic captain, "He had more courage than was good for the rest of us."
It's not mentioned that all destroyers are lively in a rough sea, though three were sunk in a typhoon. Ships that size, roughly 300 feet or a bit more, have a tendency to roll. I was a seaman on a Coast Guard cutter that took a roll of at least 40 degrees and dumped everyone and everything against the bulkhead. And that was in the smiling seas around Hawaii. (If it were to happen today, at my age, they'd find my corpse at the bottom of the pile.) The Fletcher DDs, though, deserve whatever accolades they get.
