While reading the new book on the Iowa by Lawrence Burr,1 I stumbled across a statement that threw me for a loop. He claimed that after the bombardments of Japan in July 1945, Iowa was ordered back to do gunnery practice at Kaho‘olawe in Hawaii, shooting on July 29th and 30th, and explicitly pointed out that she missed several airstrikes Third Fleet conducted during that time. This was a baffling thing, and I was having trouble believing it had actually happened. Third Fleet was off Japan at the time, and every effort had been made to keep as many ships forward-deployed at sea as possible. A massive underway replenishment apparatus was built, and when that wasn't enough, mobile bases were constructed at islands across the Pacific. Ships only got sent as far back as Hawaii when they needed serious yard work, more than could be done in the forward-deployed floating drydocks. And absent battle damage, that typically didn't happen until the ship had been on the line for a year or more. Iowa had been stateside until the end of March for a refit, leaving her as the least likely ship to be sent back.

But even beyond that, this story didn't make sense on several levels. First, doing this would have deprived Third Fleet of a powerful anti-air platform while conducting air strikes on the Japanese mainland. Strikes were flown on July 24th, 25th, 28th and 30th, and further strikes in early August were cancelled due to weather. Given the distance between Japan and Hawaii, even at 20 kts, her maximum plausible cruise speed, Iowa would have taken a week to make the trip, and it's over 9 days at a more typical 15 kts. Second, even if Iowa's gunnery during the bombardments was so bad that more training was urgent, there was no reason to send her all the way back to Hawaii. All you need is an uninhabited piece of land, maybe with a smokescreen if you want to practice air spotting and make sure the crew doesn't cheat. This wasn't exactly difficult to accomplish in the western Pacific, and by doing it in the Philippines or even off Okinawa, the amount of time the ship is out of action is greatly reduced.2 Read more...
