I am way behind the times and am just now reading about the DD(X)/Zumwalt fiasco and lol they don't have any ammunition for the guns because each round was going to cost as much as a Tomahawk?! Is there any effort being made to make conventional ammunition for the Advanced Gun System, or is that just throwing good money after bad since I'm not sure how useful shore bombardment really is? I guess a shell is probably harder to shoot down than a missile, but don't the Israeli's or someone have stuff for shooting down mortars etc? Do they have any actually useful armament or are they just floating piles of sensors that are hard to detect? I guess a sneaky spy ship is sort of useful, but they seem mighty expensive for just being a toothless sneaky ship.

I read that the LRLAP was theoretically accurate to within ~150 ft at ~80 nautical miles which seems pretty impressive (and it ought to be at $1,000,000/rd!), but how accurate is modern artillery generally? I was always very impressed reading about WW1 Dreadnought actions where they seem to be able to hit a pretty skinny ship at 20,000+ yards with stereoscopic manual rangefinders, so presumably this has improved considerably.

yes, the AGS is a total dumpster fire, but they've still got 80 VLS cells; i'd hardly call that toothless.


edit: to expand on that, a lot of the technological innovations on the class are proving themselves right now, like the advanced powerplants and electrical distribution, hullform, battle management systems, etc, and will filter down to production fleet hulls, just like Seawolf did for the Virginias, despite the small procurement. a classic death-spiral procurement case, but not totally useless like, say, LCS.

anyways, the best shore bombardment the US has ever had will always be the SSGN converted Ohios

They have the same problem as all the procurements from that era: f35, Ford, LCS. They crammed every bit of high tech next gen into the platform as they could and like and behold some of it was wonky and needs more work so they’re troubleshooting ten almost-prototype technologies at once in a full production vehicle rather than individual test beds

You can’t load the tubes from below so you’d need a good way to get them to the deck and loaded from above. Basically their own dedicated elevator and crane near the VLS, with a pretty large surface to service 96+ tubes (or duplicated if the VLS are dispersed). It might be possible but probably a lot more effort than it’s worth. The strike length canisters (Tonahawk, SM-6) are very long.

Turn half the well deck into a VLS bank? Yes please lol!

The cranes on the LSD would be perfect. They have access to the well deck, plenty of vertical clearance too. I bet you could put 100+ vls on a refit LSD.

I drove by his house (since he was in the area) hoping to get a picture or two, but decide to abort because there were already a couple dozen people who had the same idea and I didn’t want to crowd the overly stuffed street. However, in defense of neighbors asking him to move the tank, it toke up almost 2/3rd of the street and was tight squeeze even for my small Corolla.

Not in the infrared wavelengths used to heat things up. You need a cryo-cooled MWIR or exotic SWIR to see the spot. Both are very expensive to make. Also, if it’s a narrowband IR laser, there won’t be enough scattering in the atmosphere to show a line.

There’s a hundred reasons why submarines won’t be using lasers to shoot down ICBMs, but making an easily visible line back to the sub ain’t one of them, chief.

Crypto AG, a Swiss cryptographic communications gear company that got its big break building code-making gear for the US Army in World War II, has been a provider of encryption systems for more than 120 countries. And according to a report by The Washington Post and German broadcaster ZDF, the company was owned outright for decades by the Central Intelligence Agency and Germany's intelligence agency, the BND—allowing the CIA, the National Security Agency, and German intelligence to read the most sensitive communications of practically everyone but the Soviets and Chinese.

Apparently 80-90% of Iran's communications during the Iran-Iraq war might as well have been in plain text as far as US intelligence was concerned.

I like how you condescendingly added the last bit. Crushed 'em

Still though I wonder if you're right. IDK much about this subject but a little googling suggest that solid state 10kW welding lasers output around 1.03um. https://www.sciencedirect.com/science/article/pii/S1875389213000655

Makes sense that these would be pretty similar to the shipbourne systems, e.g. https://en.wikipedia.org/wiki/AN/SEQ-3_Laser_Weapon_System

Lastly, it seems that a cursory search of digikey will net IR sensors that DO detect in this spectrum, although not at peak performance.
Heres a few datasheet snapshots of ~$3 sensors from digikey.

Would take welders a few days to build a few upsized trebuchets, and then you can just launch bags 24/7 from ~300m away.

That $3 sensor is not an imager. You’re not getting that thing to display anything other than a voltage output indicating the presence of SWIR radiation.

You’d need something like this: https://www.oemcameras.com/tau-swir.htm?gclid=CjwKCAiAvonyBRB7EiwAadauqSrtUNMy_3BK2PsPdOXyf8wEuxAmHhNVA6SkU-k7Rzw_r8qtk4VC4BoC6-AQAvD_BwE

But again, you’re not going to get enough atmospheric scatter to see the beam.

I’ve worked with military laser designators in the 1-2 nanometer range for years and it is fairly easy for a special camera to see the spot, I have never once seen the beam itself.

Mostly because once you get to a certain level of sophistication you need to have some heavy duty specialists working on it. Imagine you're Portugal or Jordan. If you try to home brew a cryptography solution using only domestic resources, is it really going to stand up to cracking by the US or USSR? Or do you find what you hope is a trusted outside source and have the best cryptography you can buy, even if you don't have the experts to make it yourself?

It's the same basic problem that a lot of countries have with high tech products. Is a Portugese domestic air superiority fighter ever going to be able to go toe to toe with what the French or Brits are making, much less the US or Russia? Is it better to have an inferior domestic version or find a hopefully trustworthy major power to buy some last gen fighters from?
