Sea Sparrow

While the sinking of the Eilat is often singled out as the origin of modern anti-missile systems, this isn't really true. The first SAM systems were built to plug the most glaring hole in naval air defense and give ships a way to shoot down high-altitude attackers, but as soon as these were in service, attention turned to something that could protect against sea-skimming aircraft or missiles. The 20mm and 40mm guns that had provided close-in defense during WWII were inadequate in the jet age, and the new system would need to be able to react quickly, have a high kill probability and be light and cheap enough to fit on every ship. Initially, the USN planned to fill this role with the Sea Mauler, based on a short-range air defense system being developed by the US Army. This would use an automatic fire-control system, with targets simply designated by the operator, and beam-riding fire control that would let it be used close to the sea's surface. Unfortunately, this weapon was well ahead of its time, and various technical and programmatic problems led to its cancellation in 1965, leaving its potential users scrambling for a replacement.

The land-based Mauler prototype

The Army decided on a combination of the M61 Vulcan 20mm gatling gun and the AIM-9 Sidewinder for its short-range air defense efforts, but neither system was immediately suited to the Navy's needs. The Sidewinder took too long to lock on, and the models available at the time were only able to lock on to targets flying away from them, a particular problem when trying to defend oneself against incoming missiles.1 Vulcan had the potential to be useful, but it would obviously be a last-ditch weapon and it would take a while to build the systems to make it effective.

are ships delicious

hello this is dean the cat

i have been looking forward to asking this for some time and the humans are finally busy so i can share this with you

a while ago the big human was talking about birds like the awk and the osprey and after looking around for a while and not seeing birds i realized that it was talking about ships that were also birds so i wondered if ships were delicious like birds but it never understood me when i asked and just made fun of me by making noises

so ive been trying to find out but because it doesnt have one of these ships i decided to see if the books tasted good although the big human doesnt seem to like this and keeps yelling and me and pushing me away whenever i go for a taste

there are so many of these books in the house that it shouldnt be a problem if i eat one or two right

maybe some of you can convince it to let me taste the books or to get me a ship that tastes delicious

i am tired and will take a nap now

Nuclear weapons are not as destructive as you think

How destructive are nuclear weapons really? This is a question that seems to be asked far less often than it should be, and is rarely discussed in a non-alarmist way. In fact, nuclear weapons are not a threat to humankind, and we can expect a vast majority of people to live through a nuclear war. None of this is to say that nuclear war wouldn't be a big deal, or a terrible humanitarian catastrophe, but it wouldn't be enough to wipe out civilization, much less the human race or all life on Earth.

We should probably start with a look at the state of the global stockpile, because it's fallen dramatically in the last 30 years. After peaking at around 70,000 warheads in the mid-80s, it's fallen to only 12,700 according to the Federation of American Scientists. The majority of these are in the reserve stockpiles of the United States and Russia, which are there in case the current arms-control regime fails, and would take time to deploy. Denying the other side this time is undoubtedly a major objective of both nation's nuclear forces, so in practice, we should instead look at deployed warheads. Arms-control treaties limit both nations to 1,550 deployed warheads, although FAS estimates 1,588 for Russia and 1,644 for the US, probably due to slight differences in definitions. Worth adding to this are the Chinese (380 warheads), the French (280) and British (120), for a global total that we can round to 4,000 warheads for simplicity. Some of these won't work, or will get shot down, but we can assume that other nations and the surviving stockpile weapons will bring the total back up. Note that this is a worst-case all-out nuclear war, and there are potential off-ramps short of it even if there was, say, a tactical nuclear exchange in Eastern Europe, although they aren't certain.

Southern Commerce Raiding Part 6

Previously, we discussed the how the State Department’s shrewd overseas maneuvering successfully stymied Southern hopes for procuring a European ironclad fleet, while Confederate agents had more success building commerce raiders in England, shielded by paper-thin legal technicalities and tacit English consent. The first English-built commerce raider, the Florida, had failed to damage much on its initial cruise beyond Northern egos, but that was set to change.

CSS Alabama at sea

In 1862, the most famous of the Confederate raiders, the Alabama, set sail. Like the Florida, she has been constructed in England. In this case, however, Charles Francis Adams was actually able to gather enough proof of the ship’s wartime purpose to compel English authorities to move to detain the vessel. Acting with admirable decisiveness, Bulloch took her out for a “trial run” and escaped detention, thus saving her for a remarkable career afloat. Read more...

Early Lessons from the War in Ukraine

I figure it is about time to write a longer piece on the war in Ukraine, and what lessons we can draw from it. I'm going to focus mostly on what we have learned so far, and leave my prognosticating to DSL and the comments.

The first lesson is a very old one, best summed up by something Napoleon almost said. "The moral is to the physical as three is to one". Morale and motivation matter a lot. This isn't to adopt the Imperial Japanese approach that they would win because their will was stronger even in the face of overwhelming firepower, but if one side wants to fight and the other doesn't, then the side that doesn't is going to have a very hard time of it. While there are lots of ways to motivate people to go fight, the easiest is to tell them "Bad guys have invaded our land. They're going to destroy your home and enslave or kill you and your family. You need to stop them and you can stop them." So long as people keep believing all of that, they will keep fighting, and it was obvious from the start that the Ukrainians believed. Given that, everything we've seen since then has been pretty much inevitable. Read more...

Letters of Marque Today

Every year or so, I run across proposals for Congress to issue Letters of Marque and Reprisal, something it has the power to do under Article 1 Section 8 of the US Constitution, most recently in the context of the war in Ukraine. All of these proposals are stupid on many levels, although explaining why will require an explanation of the history of such letters, both why they existed and why they're obsolete and shouldn't be used again.

A letter of marque is at its core a document that grants its holder the power to seek out and capture enemy vessels as prizes, a power normally reserved for commissioned warships. Without a letter of marque, a private vessel doing this would be a pirate, and even with said letter, it's not just "finders keepers". The prize has to be sent into a port to be condemned by an Admiralty Court as a legitimate prize. If it wasn't judged to be a proper capture, the ship would be released back to its owners, although the details of how this was done are outside the scope of this post. Read more...

Open Thread 99

It's time for our regular open thread. Talk about whatever you want, so long as it isn't culture war.

Book update: 56,000 words and counting. Mostly working on the dreadnoughts in the ~1910 period.

Also, it's about time for another virtual meetup. Next one will be Saturday, March 12th, at 1 PM Central (GMT-6).

A lot of you probably know about the HNSA booklets of general plans (quite detailed construction drawings of warships), but I have just found another source. The US National Archives have a bunch, too, including a lot of ships which aren't in the HNSA collection. Unfortunately, their indexing is rather messy, and not everything which shows up in their system is digitized. Best bet is to just search "booklet of general plans" plus an identifier for the type of ship you're looking for. Note also that if you do go through an index link, it applies whatever you have in the search bar on the previous page. Sadly, Iowa appears to be among the ships which hasn't been digitized yet, but I live in hope.

2018 overhauls are Propulsion Parts one, two, three and four, Strike Warfare and Late Night Forward Pumproom Test. 2019 overhauls are my reviews of museums in Singapore, Commercial Aviation Part 8, A Brief History of the Cruiser, Pictures - Iowa Engine Room and Spanish-American War Part 2. 2020 overhauls are Proximity Fuze Part 2, The Range of a Carrier Wing - An Experiment, Pictures - Iowa Enlisted Mess and Merchant Ships Introduction and Passenger Vessels. 2021 overhauls are The Designation Follies, Naval Airships Part 3, NWAS Soviet SLBMs Part 1 and NWAS Polaris Part 1.

The Battleship Review

Unlike most of the other movies that have gotten a full-post review, I have seen Battleship before. It was while I was in LA, volunteering on the Iowa, and to avoid burying the lede, I rather liked it. I'm not saying it was a good movie (because it's pretty much what you would expect from a movie that's an attempt to capture a piece of the audience from the Transformers series, based on a board game) but it's silly enough that it's fun. Plus, there's a strong element of wish fulfillment in the climax for me.

Which isn't to say I don't have gripes. WHY ON EARTH WOULD YOU USE LANDSAT 7 AS A TRANSMITTER FOR TALKING TO ALIENS? Landsat 7 is a remote sensing platform, very useful if you're trying to map out flood damage to crops, but almost literally the least suitable satellite for the mission in question. (Why yes, I have used Landsat 7 data in college. Why do you ask?) And the satellite they use on-screen looks nothing like it. Also, as per my usual policy, I will ignore the romantic subplot.
