Merchant Ships - Icebreakers

Ice has long been a serious problem for shipping. For centuries, northern ports, particularly in the Baltic and Northern Russia, would spend several months of the year icebound and unable to take part in the benefits of maritime trade. In special circumstances, a port might cut a channel through the ice, as Boston did to free the Cunard liner Britannia in 1844, but this was rare due to its difficulty. It wasn't until the dawn of the 20th century that a way was found to reliably break ice and let merchant ships through.1


Britannia leaving Boston

The first modern icebreaker was designed and built in Britain for the Russians, and named Yermak. She entered service in 1899, and served in the Baltic until 1963, a testament to the soundness of her design. Yermak had all of the features common to modern icebreakers: a heavily reinforced, rounded hull; a steep slope to the bottom of the bow to let it ride up on the ice, and lots of power. Icebreakers don't do their job by simply cleaving ice in two. Instead, they take advantage of ice's low flexural strength to ride up on top of the ice and break it with their weight. With extremely thick ice, such as pressure ridges, this can mean essentially beaching the icebreaker on top of the ice, or even having to back off and hit the ice at full power several times. In most cases, though, nothing this violent is needed and the ship simply pushes the ice down under her hull, fracturing it as she goes. Read more...

The Reagan Maritime Strategy

From the earliest days of the Cold War, there was controversy over the the US Navy's role in fighting the Soviets. Initially, the Air Force tried to cut them out entirely, but they managed to sell the carriers as nuclear strike platforms, retaining the mission into the 60s, when the ballistic missile submarine entered service.

But in the 1970s, with the post-Vietnam drawdown, detente with the Soviets and the Carter Administration, Western leaders began to focus more and more on the Central Front in Germany. Sea power was seen only as important for ensuring the passage of convoys across the Atlantic in the face of Soviet submarines. The carrier force was allowed to run down, and shipbuilding concentrated on ships specialized in ASW. At the same time, the Soviet Navy, under Admiral Sergey Gorshkov, had begun to transform itself from the coastal-defense force it had been under Stalin to a true blue-water fleet, with the ability to hunt ships and submarines anywhere on the seas, a capability reinforced by larger and larger exercises. The Western navies, on the other hand, had scaled back their exercises, preferring to operate well away from Soviet waters. Read more...

Aurora Game 1 - Fleet Building

I've added all of the ships from the Setup thread into an updated database. I plan to make actual allocations during the virtual meetup, with actual play beginning next week. But that means I need actual direction for the fleet, beyond "a Tourville or two". The updated database should make it easy.

Post-meetup, we've added a number of new ships and variants on existing ones. New database.


The French Republic's first trip to another star took place on February 1st, 1960, when GSV Caelum transited to Bernard's Star. I've uploaded a new database here. I also discovered that the jump drive system has been tweaked, and that now military jump drives apparently can't carry commercial-engined ships. To get out of the pickle this placed me in, I went in and gave us the next level of jump drive tech, which actually shrank the ships slightly, so I topped them off with more fuel.

Naval Bases from Space - San Diego

Continuing our series that started with Hampton Roads, it's time to take a look at San Diego through the lens of Google Maps. While it's position with respect to the Pacific Fleet isn't quite as overwhelming as Hampton Roads is for the Atlantic Fleet, San Diego is still home to a huge number of ships and aircraft. It's also close to my heart, as it was where I first went to sea. You can follow along with the Google Map I created for this post here.

The core of this facility is Naval Base San Diego, on San Diego Bay south of downtown. This is a surprisingly recent base, being established thanks to the efforts of the San Diego community in the aftermath of WWI. Before that, the majority of the Pacific Fleet was based either in San Francisco Bay or the Los Angeles area. During the interwar years, it was mostly home to destroyers and submarines, but it emerged as the premier West Coast base in the aftermath of WWII. Today, it's the homeport to a significant fraction of Third Fleet's surface warfare and amphibious ships. We'll start at the south end of the piers,2 where we find America (LHA-6, the best of the ships we'll look at today) and Makin Island (LHD-8). 3 Across the pier from Makin Island is a San Antonio class LPD. The next pier north has a wide range of ships. There's Michael Monsoor, the second unit of the Zumwalt class, another LPD and a Ticonderoga. Read more...

The Seaplane Striking Force

In the years before WWII, there had been serious discussion of the use of flying boats as long-range bombers. Unfortunately, the late 30s saw land-based aircraft improve to the point that waterborne planes couldn't hope to keep up, and their strategic operations during the war were limited to one strike against Pearl Harbor. And after the war, the flying boat was gone for good. But it almost wasn't that way.


The P5Y, the first of the new seaplanes

The first factor was the work of aerodynamicists in the late 30s and early 40s. Flying boats had always been hindered by the need for reasonable waterborne performance, and by the late 30s, the demands of taking off and landing imposed an intolerable cost on their airborne performance. But several teams in both the US and Germany challenged this accepted wisdom, discovering new hull forms that allowed flying boats to be much longer relative to the width of their hulls, narrowing the performance gap with their land-based counterparts. By the late 40s, Convair had several designs that should work quite nicely, and was under contract by the Navy for a new patrol plane, the P5Y, which could fulfill these promises. Read more...

Open Thread 65

It's time once again for our Open Thread. Talk about whatever you want that isn't Culture War.

The USNI Christmas Sale has begun! It's slated to run through December 31st, so you have plenty of time. Everything is 50% off, and has free shipping, so there's no better time to build up your naval library. I have a lot of shelves that are filled entirely with books from the Naval Institute Press. Hopefully, they do a better job than last year of filling orders, and my experience so far this year has been positive.

Books I'd suggest taking a look at include the various volumes of Friedman's illustrated design history series (including the spectacular US Battleships and the long-awaited reprint of US Cruisers). If you want to know what's going on today, try the 2021 Seaforth World Naval Review. They don't seem to be doing the usual Morison bundle, but you can still get the 14 volumes individually at a very good price. Other good choices are Freidman's World Naval Weapon Systems and Network-Centric Warfare and Brian Lavery's superb Nelson's Navy. There's a lot of other great stuff available, and I'd encourage you to take a look, particularly through the Clear the Decks discount collection, many of which are in the $5 range.

Also, this is the one time a year when I mention that Naval Gazing takes donations through PayPal, if anyone wants to donate and doesn't think I have enough books already. I have a good job and really don't need the money, but the option is open and all proceeds will go to expanding the library.

2017 overhauls are Iowa parts two, three and four, Fire Control Part 2, Ballistics, US Battleships in WWII and the Battleships of Pearl Harbor parts one and two. For 2018, I overhauled Russian Battleships Part 4, Operations Research in the Atlantic, my review of the 45th Infantry Division Museum, Armistice and museum ship lists for Europe and the rest of the world. Lastly, 2019 overhauls are Early Guided Weapons parts one and two, Natick Labs and Glide Bombs.

The Alaska Class Part 2

As the naval treaties lapsed in the late 30s, a new type of ship became possible, something more powerful than the treaty cruisers but smaller than a full-size battleship. Several nations looked into building this kind of ship, but only the US actually built them, in the form of the Alaska class large cruisers. The process of actually reaching a consensus in favor of the ships was tortuous, and things got even worse when it was time to actually design them.


Alaska on her shakedown cruise

The first batch of design studies were an interesting hybrid of cruiser and battleship practice. Unlike contemporary cruisers, they were given a proper TDS, although one designed against a 500 lb charge instead of the 700 lbs of the Iowas. The inner edge of the immune zone was set at a much shorter range than was common for battleships, as a ship operating independently might well have short-range encounters that a battleship's screen would intercept. Three of the four were to be protected against the extremely powerful 12" gun, which in turn pushed up size and led designers to use more elements of battleship practice. This formed a vicious cycle, and the largest design from the initial phase, armed with 12 12" guns, had a standard displacement of 38,700 tons, larger than the North Carolina and South Dakota classes. Another, with 9 guns and a bigger immune zone, actually had a thicker belt than the Iowas. All of these designs were rightly seen as too big, with two Iowas costing as much as three of the smallest design armored against the 12" gun. Read more...

The Alaska Class Part 1

Possibly the most controversial vessels built by the United States during WWII, the Alaska class were unique ships, somewhere between a battleship and a traditional cruiser. This hybrid status has led many to dub them battlecrusiers, although this is a reading that does not hold up in view of the history of that ship type. Instead, the role and design history of the Alaskas is best summarized by their official designation as Large Cruisers.45


Alaska

The Alaska class was the result of the 1936 London Treaty. The idea of a "cruiser-killer", capable of hunting down treaty cruisers but lighter and cheaper than a battleship, had long been attractive to the various navies. However, none had acted on it because of the treaties. Anything above the treaty limits for cruisers would have come out of battleship tonnage allocations, and nobody was willing to sacrifice full-size battleships to get cruiser-killers, even at a reasonably favorable exchange rate.6 The French came closest with the Dunkerque class, which was a moderately specialized design primarily intended to hunt the Deutschland class Panzerschiffe, but even these were essentially downsized battleships, with the design features and roles that implied. But after the Second London Treaty, with all restrictions on total fleet size abandoned, the USN decided the concept was worth a second look. Read more...

Aurora Game 1 - Setup

Gentlemen,

Since researchers at the École Polytechnique discovered Trans-Newtonian elements in the mid-30s, France has gone from strength to strength. This technology was revealed to the world in 1937 when Germany attacked us again, and we used it to comprehensively destroy their fleet in the North Sea. That war ended with Germany under French occupation, an occupation that continues to this day. We have spent the intervening years investigating these technologies, and the English and Americans have agreed to join forces under our leadership to exploit the cosmos. Now is the time for France to take her place not only among the nations, but among the stars!


So yes, the Aurora game ended up as a sequel to the RTW2 game, and it's now time to begin with the building of ships. I'm going to leave this in your hands. I've attached the starting database, so you can simply download it, unzip it, place it in your 1.12 Aurora game, and start designing vessels. Note that you'll need to design most of your own components, although I've pre-researched some basic stuff like the standard beam weapons. Post the resulting statblocks in this thread, and we as a group will decide what sort of ships we want. In some cases (transports) this should be pretty straightforward. In others (warships) it's going to require figuring out what sort of weapons we want to work with (beams, missiles, fighters), and then building the ships to use them. Feel free to do as much or as little building as you want. Also on the table is the general industrial/research direction we want to take, and the ground forces, if anyone is interested in building those. (If not, I'll just handle that myself.)

I plan to let this discussion run for the next week, with a possible extension if things haven't been settled. At that point, I'll take the general direction of the group and implement it in the master DB, then begin play. Because Aurora is a lot more free-form than RTW2, I don't have a defined time I'll play for. Probably until something interesting happens.

Do note that I plan to stay out of the discussion as much as possible, with a few exceptions. I'll audit all designs to make sure they make sense (so, for instance, a ship that's bigger than your shipyards won't be allowed) and I'll reject anything which requires too much micromanagement on my part. Yes, your 13-ship, 4-design survey squadron is very cool and would be very efficient, but running it is going to suck a lot of the fun out of the game for me, and that's bad for the longevity of the game, as well as being annoying.

Coastal Defenses Part 6

In many ways, the last years of the 19th century and the first decade or so of the 20th were the golden age of coastal artillery. While the guns themselves might be no more powerful than those taken to sea, and the ability of fortifications to stand up to direct hits was dubious, weapons mounted on solid ground were far more accurate than those on a moving ship, and could thus strike at greater ranges.


A coastal battery at Port Arthur

As with previous wars, coastal defenses played an important part in the conflict between Russia and Japan. The batteries protecting the Russian base at Port Arthur were unable to prevent the surprise torpedo attack that the Japanese opened the war with, but they were quite effective at driving off a Japanese attack the next day. Despite some initial problems, these batteries continued to be effective in keeping the Japanese at bay until Port Arthur was taken from the landward side. The siege also saw the Japanese use 11" howitzers to sink most of the ships of the Russian Pacific Fleet. The fact that the Army had sunk the ships was a significant blow to the Japanese Navy, although they were able to redeem themselves at Tsushima. Read more...
