HMS Irresistible (1898) was the second of three Formidable class pre-dreadnought class ships built in the late 1890s. Outclassed by newer ships at the outbreak of the First World War, she was used to shell defenses of Dardanelles Straits that separate the Mediterranean and Black Seas. In March of 1915 she struck a mine, which ultimately lead to her sinking with approximately 150 of her crew.

Record Group 80-G - the blog post 18 months in the making!
I had intended to do this a while ago, but found after my October 2012 trip that I had missed a few crucial photos and decided to wait until I had them. Well, I still missed one, but I'm not waiting another 12 to 18 months!
80-G is a sub-section of Record Group 80, "General Records of the Department of the Navy, 1798-1947." It is an all-photographic collection and is Officially titled "General Photographic File of the Department of Navy, 1943 - 1958." The dates are actually incorrect in that there is a bunch of photos that are pre-war. By most standpoints it is a mess - there is not an orderly progression of photos but rather a mish-mash turned over by different commands within the Navy. There are duplicates and subjects that repeat as different groups may have turned in the same photo or set from their internal records. Some times reproduction is poor as the copy is the 5th or 6th generation plus from the original. There are gaps where photos were stolen or damaged beyond use and discarded, and NARA has not the budget or time to replace these from the negatives that are stored separately.
That said, it is a treasure trove of photos - 2861 boxes of photos taking 600 linear feet of shelf space in the archives. That many photos makes for an unwieldy data set - one can't simply google the subject and have all of them shown to you. It starts, with a card catalog:
Looking for ships is relatively easy, although there's no guarantee you will find any photos of the ship you you are looking for. We'll stick with ships though, for this blog post, just to keep things simple. Once you find the card box containing your ship name or hull number, you can pull it out and start thumbing through the cards. If you're lucky, it will have a small copy of the photo along with the caption, but not always:
While this can be a little tedious, the whole experience is starting. The researcher has to make a note of every photo number of interest, then take that list to a finding aid that will help match the photo number to the box. A savy researcher will either have a list of photo numbers and boxes, or will turn in a request for one or two boxes just to have something for the first pull, as it may take a couple of hours for your boxes to make it out to you on a cart. After the first pull slip has been filled out and turned in, you can continue matching up numbers and boxes, and build up a list for the rest of your trip, or future ones while waiting.
Compared to the textual records and other photographic records, filling out a pull slip for 80-G is pretty easy. One just needs to know their name, researcher number, date, the fact that they're pulling from 80-G, and the bos number. If multiple boxes are desired, you can enter a range, but it has to be contiguous. SO, you could pull boxes 100-110 with one pull slip, but if you wanted 100-110 plus box 120, you would need to do two pull requests. As you are limited to two carts in total, and only one out at a time, it's wise to be a little paper-heavy instead of just pulling large swaths. Unless, your goal is just to go through the whole series a box at a time!
But then, the boxes start arriving!
Inside, are folders with the photos mounted on thicker cardboard cards - this helps protect them and also provide space outside of the print for caption data - date, location, subject, etc..
Hard drive space is cheaper than time at the archives, so I usually set my scanner to save the entire platen, and scan as much of the photo and card as I can. When the photo is full-sized, I usually lose the left inch or so of the caption, but I at least have the date and some of the pertinent information on the card in case I miss anything when note-taking as I scan.
One downside to the cardboard backing is that the edges get beat up over time and start to shed fibers - this shows up as dust on the platen that can show up in the image, so it wise to either wipe the plate clear every couple of scans with the white cotton gloves that are required wearing when handling photos, or with a microfiber cloth / cleaning cloth of your own.
So, that's a little bit of what 80-G is like. Textual records at NARA II or the regional archives are completely different, and takes more thought and planning, so many researchers confine their searches to just 80-G or other photo-only record group accessions. It certainly can be a lot of fun!

Random Photos - Puget Sound Naval Shipyard Charleston Gate, 1943
These were recent scans from Seattle NARA - the Charleston Access Gate at PSNS in 1943. The gate is currently here, but I don't know if this is the same location as it was in 1943, or if it was moved in or out.
The below photo was captioned "Machine gun nest protecting Charleston Gate," on the back, and there's really not enough information to locate the exact position at this point. It does not look like terribly exciting duty, but I would imagine there were a lot of sailors and Marines who enjoyed the shore duty stateside over being sent forward in the Pacific for a year or two, if not longer.
These were out of a group of records on "Passive Defense" for the shipyard, which were the same source as the Passive Defense Handbook, posted earlier.

BB-37 Oklahoma Torpedo Defense System, Pt II
The below side-view shows the added torpedo blister and the armor belt. Note that this is from the Booklet of General Plans and is reversed to show her port side, which explains why the text is backwards. As you can see, the first two hits were below the armored belt. A similar hit on Nevada punched through the dry blister voids and ripped in to the two fuel-oil filled voids inboard of that with enough force that the main bulkhead protecting the innards was then dished in roughly two feet and the compartments began to flood.
As you can see, the hits were fairly bunched up, and the armor belt took a beating. The plates where hits three, five, and seven occurred did not come back up with the ship, although whether they were blown free or pulled free when she was rolled upright is not known.

USS Oklahoma Torpedo Defense System, Pt I
I've been working on understanding the death of Oklahoma better so I can explain it to others, and I thought a good visualization of her Torpedo Defense System might help. This is the lower three levels of the ship, below the armor belt. Red is oil (fuel oil, diesel, etc.), blue is water (feed water mostly) and the medium blue are empty voids (air).
This is downsized from the original - not meant to be the final posting, just showing the start of a new project.
More fun than counting individual oil bunkers, anyway....

Sketches
"The yard proposes to scrap all materials listed as obsolete on Sketch No 102880, Sheets 17 to 25 inclusive..."
A sketch is supposed to be a simple, quick drawing, so on one hand it blows my mind that the Navy had sketches that were at least 25 separate sheets, but on the other hand, if anyone could do it, it would be the Navy!

Small Victories
Last year, which scanning in photos of aircraft carriers, I came across this photo of a corvette:
No idea what it was at the time, but I like Corvettes, so I scanned it in. I came back across it a couple of weeks ago and finally researched the pennant number to try and find out what ship it was. I was able to match it to HMCS Riviere du Loup, but there were absolutely no other photos of her that I could find on the internet.
So, I created a Wikimedia commons account and uploaded that baby.. it's now on her Wikimedia page, the first and so far only photo of this quiet ship on the internet. Hopefully it will be of use to someone.... a small advancement at best, but one nonetheless.

Random Photo - PBM Mariner Rescue, 1942
VP-74 PBM Mariner piloted by Lt Joseph A. Jaap delivering survivors of the S.S. San Arcadio to Bermuda on Valentines Day, 1942. Jaap was awarded the DFC for the open-sea landing that rescued nine sailors of the British tanker, sunk by U-boat at 38-19 N, 63- 50 W.
According to War Diaries in Record Group 38, "Oh 26 January the S S SAN ARCADIO, a seven thousand ton British tanker with fifty officers and men, put out from Houston, Texas, loaded with oil and bound for Halifax, Nova Scotia Five days out, in position 38-19N and 63-50 W, at about 2200 LZT, they were torpedoed first aft and then forward on the starboard side After fifteen minutes of effort to make radio contact the ship was in such condition that it had to be abandoned 74-P-7, Lieutenant J. A JAAP commanding found nine survivors in position 34-28N and 62-50W The plane landed at sea, took the personnel aboard and returned them to Bermuda. As a result of this action Lieutenant Joseph Abraham Jaap, USN, was awarded the Distinguished Flying Cross."

Using NARA's OPA
On the plus side, results are now persistent and you can link to or bookmark them. Previously,results were temporary based on a live database query that would close out after 30 minutes of activity, so you could never send results to a friend and say "hey, check this out!" I took to saving each interesting result as a Word Document for quick reference later.
This new one changes that, but it also really doesn't work well if you don't already know what you're looking for. If you didn't know that records are generally separated into titles such as "general correspondence," or "classified correspondence," when what would you search for?
I can, at least search for EVERYTHING in a record group at a specific location, but if I search for all of record group 19 at NARA II "textual records" I get over 15,000 results. I'm having some luck - I tried searching for "naval" in Record Group 181 at NARA San Bruno and then hit the "refine by series" link, which listed all 58 of the listed accessions they have information posted about, including one for the 14th Naval District (Hawaii, essentially):
Fourteenth Naval District. Office of the Commandant. General Correspondence, 1925 - 1957
So... learning by stumbling about.
