  1. Not that I’d want to take incoming from a 5″, but I think it a wee bit sad that the Navy’s biggest gun is less than 1/3rd the size of the biggest gun from 75 years ago.

  2. Given that the vast majority of ship sinkings were accomplished via torpedoes, dive bombing, or mines, it’s not that much of a surprise.

    Those 16″ rifles do kick buttock when it comes to fire support… 🙂

  3. Badgers smile gently at anything less than the Rifle 16’/50Cal. MK-7. ( Actually, we love our 5″ers, and believe each warship should have at least 2 )

  4. What are those that look like puzzle pieces are the fore and rear of the gun (port and starbard of the ship, and I guess technically the gun) on the deck?

    1. Rubber mats like you’d put down on the floor of your garage. They protect the deck from the shell casings when they’re ejected. They come out from right next to the barrel, shooting forward, and they’re moving pretty fast when they come out. They’re made of steel, and when the mouth of the casing hits the deck they’ll chip away the non-skid just like you were using a very high-velocity (and very hot) putty knife on it.

  5. Hey Lt. Rusty, thanks for answering. I saw that they were rubber mats (after reading the linked article, that’ll teach me to read before posting), but I still have one question; I understand that you pack powder charges and “loose” projectiles, so from where do the steel casings come? Are they part of the powder charge? I imagined that they’d be an easy way to transport the powder to the bore, but wouldn’t a predefined charge require precise elevation on the gun to hit the correct coordinate? Maybe that’s the way the gun works, but forgive me. I’m a mortarman, so I’m used to being able to vary the charge as well as elevation.

    1. Naval rifles (that is, guns) use semi-fixed ammunition, but as a practical matter, every shot is a “full charge” shot. Range is only varied by elevation.

      The ships do carry a small number of reduced charge cartridges, but only for special applications.

  6. Ah, so for the most part, a full charge is housed in a steel casing? that makes sense. at the very least, it limits the number of varibles that need to be calculated.

    I;m curious however, in what circumstance are the reduced charges used?

    1. These days, mostly only for star shells (i.e., illumination rounds w/parachute flares) and ERGMs. Since the ERGM program was cancelled, I doubt they have any left in regular inventory.

  7. Badgers fear not the bagged charge! Verily, we like 6 inch grains of propellant, loaded in 100 pound bags!
