Silent Service: Torpedo basics

…Do I have my subcorner back now?

No Dolphin randomly barging in, n-no random shipgirls asking me to explain other stuff?

Yay.

Subcorner.

Okay. Today’s sub corner is actually just something super technical. I’ve been um, doing this thing you call lurking. I have to say, a lot of people are seriously underestimating how hard it is to hit a target with a torpedo!

Just imagine. You are in the conning tower of a World War II American submarine. You’re probably standing near the attack periscope, having seen a target from your submarine. You’re gonna have to shoot well, because if they find you you might not get a chance to come home. The torpedo isn’t a smart weapon (though we’re working on that!) and once it leaves the tube, it’s done. The torpedo has to gain the right speed, depth, and course all at the same time to get a hit.

But the sleek torpedoes we find in the war were nothing like what they started out with. At the beginning, during the very early days, torpedoes were connected by wires, and they were controlled by men standing on the shore. They would control the torpedo by interacting with its rudders directly, and the torpedo’s power would be sometimes supplied by dynamos on shore.

In fact, we call the torpedo “fish” because that’s what it was. A torpedo that could swim on its own. And we’ll start by talking about the Mark 3 Bliss-Leavitt torpedo, widely seen as the first torpedo in the US navy.

Created in 1903, this basically had all the things we’d recognize as a torpedo. It could swim on its own, can control its own depth, and went pretty fast. It could go 1200 yards at about 35 knots. Don’t laugh. It was pretty impressive for something we had really no clue to make. So the navy took a closer look and though, let’s make one for submarines.

Enter the Mark 4. This one can go 2000 yards at 29 knots, and it was the first torpedo to be developed exclusively for submarines. The torpedo itself wasn’t the most impressive thing, though. Rather, with a functional torpedo in hand, the US navy set out to make something that could help the submarine captain in his task.

(This figure is taken from a book called Submarine Torpedo Tactics. Surprise, surprise, right?)

Okay, see that? That’s basically what a submarine have to deal with. To hit anything you have to know how fast the other ship is going, what angle you’re shooting your torpedo from, how deep your torpedo is traveling at so you can set the proper attack angle. You have to know how far your torpedo can go before it runs out of steam, but at the end of the day? This is a simple right triangle.

From the submarine, where I can see the ship, that’s the hypotenuse. The target’s course – where it is going – is one leg, and because (or I hope) my torpedo goes in a straight line, it forms the other leg of this triangle. Thus, all I have to do to figure things out is to do a bunch of calculations very quickly using simple trigonometry.

Of course, a ship is not going to just sail merrily along. It would also be very time consuming to do all the math by hand. So, even before WW1, we were thinking about automating the calculating process. These machines tend to be pretty simple, and they would automatically calculate an aiming point for you. I’m having trouble finding you pictures of one, but just imagine a metal object with a bunch of slides and rulers on it. It looks a lot like the DD one here.

Basically we’re talking about literally the infancy of torpedo tactics here. In a submarine this thing would be tied to the periscope. The sliding arms would go under and forward of the periscope and the officer would be adjusting the arms as the captain yelled out the target’s bearing or angle or speed or range estimates. This is before the TDC and before anything fancy, but it was enough to get the job done – or so we thought.

But, you know, once we’ve started on something, someone’s always going to ask: how can we do it better? So I thought I’d show you what the old stuff looks like before we get onto more modern things.

Silent Service: Lori

Alright. I got tired of the Roman numerals so this one’s just Silent Service. I’ll go back and edit the titles and stuff later… *yawn*

Hey. Trout. You ever notice how everyone is in a Bikini?

Yes. What about it?

Don’t you think that’s a little weird?

How so?

It’s like, 40 degrees out? I mean, that’s not freezing but I wouldn’t call it warm out either.

Your point being?

Are people here incapable of wearing a jacket?

Tog, the girls can wear whatever they want. If it’s a bikini then it’s a bikini.

But why is “bikini” the iconic representation of a subgirl?

Plenty of subgirls don’t wear bikinis. Bats don’t. Pam doesn’t either. Neither does Lori –

HEY GUYS. HOW DO YOU LIKE MY NEW LOOK?

I… see what you mean, Tog.


‘Sup guys! K9 here. Tonight’s been pretty hectic with delays and uncertainty, so I decided to poke some fun at Silent Service. Sometimes it’s nice to be able to laugh at your own creation. As any team member will tell you, at the end of it all, we just want to enjoy creating and sharing ideas. Pacific doesn’t have to be WORK WORK WORK.

Yes, that goes for you too, Je – I mean, Morgane. Anyways! Here’s Lori. Don’t worry. She still have her catsuit too. 😉


How’s your day going, Lori?

Great! Can I have the keys?

The keys to?

Ammo dumps #2-18.

Uh, okay…

Yay! *twirls*

Today was a great day! It’s my day off so I had a lot of fun slacking off. I got up by dawn’s early light, did 300 pushups, then headed to the kitchen and made myself breakfast. There is something intensely patriotic about frying a dozen eggs while fending off Colbert’s hungry talons, but he’s getting too fat to steal bacon and sausage from me these days since Chester kept on trying to feed him that FREEDOM powder Cusk rigged up. I tried it myself and it was bleh. Tasted like fish paste. Definitely not for American consumption.

Then I cleaned up, did the dishes, and headed out for range day with Trout & Tambor & Tautog. Well, more like two hours, and as usual Dolphin was yelling at all of us. I like it better when Narwhal’s teaching. She’s nice! She doesn’t yell! I get nervous when people look at me! Then I ate like, eight double cheeseburgers and drank a gallon of coca-cola for lunch. Took a nap. Woke up. Went for a swim. Didn’t find any sharks to punch today but I did end up suplexing a blue whale that got too curious at Hata’s fishing lines. Can’t have critters stealing our dinner, you know!

Then I came home, tuned into my favorite afternoon talk radio, and started working on my all-new leather outfit. I think if I do this properly I just might be able to imbue that thing with the same quality of powers that my current outfit holds! Stars and stripes are nice and all, but a girl’s gonna want a change in wardrobe at some point. The way I think about it, if I worked on it for an hour every day, in ten years I’m definitely gonna become an expert if the war doesn’t start up.

But, even if it did? Well, I’m just going to pick it right back up once the whole thing boils over. We shipgirls are gonna have to fight, but what are we gonna do once the Abyssal War’s over? Just disappear? I wouldn’t like that.

Oh. Also! You are coming to the dance tonight, Mike, right? Better hope you can swing!

Lori, it’s a busy time around now, can’t I –

You really think an excuse involving work is going to fool a German-American shipgirl? Ha! Look here. You’re free. See? I’ve even helpfully blocked off the next day so you could recuperate.

Wait a minute. My schedule is generated and maintained strictly using the highest classification protocols, how did you –

Chester said if I sleep on an ENIGMA machine every night I’ll be able to break any encryption if I stared at hard enough.

… Seriously?

She also said that you can learn Japanese by watching those silly cartoons, so, yeah. Do you want one too? I think we rigged up a spare the other day.

Thanks, but I like my pillow just fine…


This is an emergency message insertion from Tautog.

Sleeping on top of an ENIGMA machine will not magically cause the commander’s schedules to become decrypted. At most it may give you a very mild headache for the next day. STEC also does not condone the harm of species protected under International law. As the unofficial spokesperson of this organization I am obliged to comment in order to minimize any potential misunderstanding or misinterpretation of STEC’s activities.


Tell me a bit about your namesake?

Sure thing, sir! The Type XXI U-boats were highly advanced for their era. They were definitely the best German submarines the Kriegsmarine had to offer. Tautog’ll probably have a sub corner on this, so I really don’t think I need to say more.

Downsides? They were pretty badly engineered in the sense that they weren’t really mass-producible. Dracha always say that if Admiral Donitz had his way and swarmed the Atlantic with A MILLION U-BOOTS the war would have been won before 1941, but I, um, somehow doubt that’d be the case. The Kriegsmarine, while professional, had very little actual naval combat or design experience prior to the invasion of Poland. Germany were simply outmatched by the Allies at every turn. Nevermind the fact that they were up against the British Empire who had been doing this “seapower” thing for the last several hundred years on the high seas. It was a disaster waiting to happen.

To put things into perspective, Hitler didn’t think to seriously seize the U-boat as an offensive weapon until the Sixth Army fell at Stalingrad. There’s a reason why the Type XXI were so different from the other U-boats. It was basically wunderwaffen, like the Toi-ga, the V-2 rockets, or the Me 262.

How do you feel about the Abyssal War?

Courage is the thing that keeps us free! Hella yeah! Something freedom something fighting for the rights of every man!

Eagles?


Hey, Lori here!

If my daily life sounds awesome, that’s because it totally is. As you may or not have been aware in the Action Report series, I’m an immigrant in every sense of the word. Much like the actual Type XXI U-boats that joined USN service, I willingly choose to become American after escaping from a very hostile situation that was developing between West and East Germany in Pacific’s universe.

Morgane likes to say this is for thematic reasons, but for someone like me? Of course America is the greatest planet on earth – er, I mean, the greatest country on the planet. I naturally seek out things that are “American” in nature, and I love everything there is about it! Be it going fast or riding horses or pro-wrestling or outdoor sports or shooting stuff, I want to experience everything there is that the country who had adopted me could offer. Sure, I might not be the most mature of the girls we have here in Pacific, but they say I’ve got a big heart!

Don’t let the team’s optimism fool you. The world isn’t automatically made a better place because we’re here. If anything, the tensions have receded somewhat, but they’re replaced by very concrete matters that the various countries of the world has to ask themselves if they are to survive. What happened to my country of origin – Germany – is one such example.

Do you really want to hear it? Well, okay… Here I go. It’s not a happy story, but it does have the happiest of endings.

Fractured after World War II, the two halves never truly evolved as they did in the “real world.” Even today, East Germany has very little reason to want to be whole again – while poor in comparison to the West, the USSR is prosperous enough and its rule functional enough that many of those in the East consider themselves to be citizens of the Soviet Union first, and Germans second.

Meanwhile, the … situation that resulted in my escape to America? Let’s just say, unlike your world, the shadows of Nazi Germany and the Vier Mächte never departed from West Germany. I couldn’t blame them, either. There is a growing sense that many German politicians did not truly have the interests of the German people at heart. Decades of stagnant economic polices coupled with scandal after scandal, alongside pressures coming from France and the United Kingdom created a hotbed of civil unrest. Germany was growing. She was alive. Yet she wasn’t healthy.

For years, I wandered alone. I had no friends or family to count on. I survived not because of dumb luck, but because I was one out of billions of individuals who were gifted supernaturally. Street hooligan or gopniki, I had to deal with them myself. I thought I’d be cursed to wander forever, like the heroes of those old stories, until one day governmental people tracked me down.

I played dumb, of course. I didn’t trust them one bit, and sure enough, they wanted me not because of who I am, but because of the strategic benefits that would come with having someone like me on their side. They were interested in a machine that could do their bidding. At no point did they ever consider if I even wanted to go along with their plans.

I just wanted a warm meal and a safe place to sleep. Maybe a real bed. I wasn’t interested in spy-rings or meeting politicians from East Germany. But the latter was exactly what they had me do. Someone higher up wanted to stir up rebellion in East Germany, and they needed someone like me to be the focal point for the rebellion.

“For Germany,” they told me. To them, it meant unifying with the East. With war if necessary. They know full well the weight of the Soviet Union stands alongside a heavily fortified battle line, ready to move – and respond – at a minute’s provocation. Naturally I was to balance the odds. The Soviets had no shipgirls (that was a lie, as I learned from STEC much later), so I would have been a decisive factor that would bring them victory.

How many would die? How many Germans would die in the crossfire? I was sent here to protect humanity. How many millions would die in a conflict between the West and the East?

For disagreeing with such a plan, they threw me in prison. Laughable. You know? I could have broken out at any moment I had wanted, but I was so shocked at the betrayal that I just cried in that tiny dark cell for days on end. I’m a good German – until I’m not. I’m a good girl – until they say I’m not. One minute I was destined to be a hero, and the next I’m now a Soviet spy.

Then the Soviets came, and I was buried beneath fifteen tons of rubble. They had heard news that West Germany might have a shipgirl of their own, and decided to take matters into their own hands.

“She is probably a Nazi, if she is indeed a German shipgirl.”

The Soviets knew of my existence, but that was what they had concluded based on what their own agents – some of those politicians I had met – told them. I, I said nothing during any of those meetings at all! I was silent because they told me I should say nothing. Am I a Nazi just because I’m German? I-is this what all German shipgirls have to d-deal with?

I, I’m sorry. *sniff* It’s just not fair. It’s not right. This isn’t supposed – this wasn’t …

*sniff*

T-they asked me if I wanted to retaliate. Surely I now understand the evils of communism now, right?

They didn’t ask me, hey, are you okay? Are you hurt?

They just wanted to use me as an object to further their ends.

Was this what it is to be German? Then I wanted no parts of it. I could not and did not want to be German anymore. I speak the language. I know the culture. I love our traditions. But to be German meant also to be the citizen of a particular state, and I could not support the actions of that country.

I, I just had to get away. But, where?

I had nowhere to go. I could not go to East Germany. They just tried to kill me. I could not stay in West Germany. They just wanted to use me.

They brought me to a new cell and told me to think about it seriously. So I sat in the darkness and cried. My cell had no windows, you know? You didn’t think the U.S. Embassy out of all places would have a concrete windowless bunker in the basement, but thank God they decided to lock me up there. Never did figure out why they did it either.

Anyways, I sat there. By now, I was used to hearing the footsteps of the patrolling guards. My old guards did theirs methodically without a break, always in double-time and rotating every four minutes. Here, in my new prison, I heard something different. These new sounds were loud, heavy, and uncoordinated. They were so very different. They were singing, too, and it wasn’t German.

At first, I wondered if I was hearing things. But, the next day – roughly an hour or so after they drop food in my cell, the footsteps would come back. With it came the song, too. Slowly, over the course of a week, I figured out what the lyrics were. It took me a while to realize that they were singing along to stuff playing on the radio.

I’m proud to be an American where at least I know I’m free.

And I won’t forget the men who died, who gave that right to me.

And I’d gladly stand up next to you and defend her still today.

‘Cause there ain’t no doubt I love this land

God bless the U.S.A.

I was taught that the Americans are a bunch of fools, and that they were dim, arrogant, and undisciplined. Yet, at the same time, there was one thing above all else they valued.

They yearned to be free.

And you know what else?

They believed in something greater.

… The rest of my story, I’ll tell you some other time. It’s no good for any of us if I just dwelled on the bad things that happened in the past.

But, I will tell you, at last, I found a place where I belonged.

I found home.


Silent Service: Cold Waters & Modern Submarines

Gah, I’ve just had it with this week. Book releases shenanigans and logistics and computer crash and loss of data gaaaaaaaaah!! It’s supposed to be a holiday! But nobody ended up getting a break.

Just relax. Sheesh. You worry more than Morgane. Go play some games. Cold Waters is fun!

Narwhal? Didn’t peg you as much of a gamer.

Oh, It’s just a little game K9 thought I should try. He said I’d be a natural. Zero agreed. So I gave it a shot.

That’s that new sub game right? Freezing Waters?

Cold Waters. Yeah. 

Okay. Just. How the heck does all of you have time to play video games? Also! HOW would you even know about video games?! This is the frigging nineteen NIGHTIES! STEC JUST figured out the internet! If this isn’t unrealistic I –

You missed the part where we literally have a wish-granting rock that, among other things, have shown to distort the time-space continuum, offer glimpses into alternative dimensions, and generates unlimited amounts of energy in the basement of Avalon, right? 

I, that’s NOT the point! *splutters*

Look here. Do y’all want to be Trout? 

Then relax. Kick back. Have some fun. Stop stressing out about the website. You do realize Silent Service is allowed to be fun right? We’ve got proper lore and then fun stuff like this. 

Aw stop it. Stop being sad. You know everyone’s working plenty hard and having plenty of fun doing this. Here. Want to try?

It’s not gonna bite ya, y’know…

… Fine. I can probably use it to do a subcorner on modern submarines anyways. How accurate do you think this game is?

Hm, well, you’ll have to dig into the details. I’m not too big on the tech stuff, sorry. 

Yeah?

Hmm, well. This looks pretty good. Yeah. Definitely could work for a subcorner with modern submarines…

(Wry grin)

So… what do you think is the biggest difference between world war II subs and the subs of today?

Well, I’d say that there’s a much larger focus on your sonar systems. Very rarely do I find myself poking up to check the periscope. I can detect, identify, range, and engage a target all underwater. No need for checking the periscope and taking measurements anymore.

So would you say it’s easier?

Not really. It’s different. You’re punished much harder for getting detected in the first place. Torpedoes now actually chase you instead of going in a straight line. Sonar systems are much more potent. Ships carrying helicopters means that torpedoes can be dropped right on top of you. I’d say if you’re found you’re way more likely to end up dead than otherwise. 

Of course, all the submarine basics are still there – as long as you stay undetected, be aggressive, and know your limits, you will be successful. If anything I think it really distills the basics quite well.

Hmm?

Clever! You’re playing the USS Narwhal. One-off boat, right? Super quiet, but kinda slow?

Well, I’m proud of her. She’s everything a submariner could ever want. Powerful, versatile, and above all else – quiet. Makes me hopeful. *wink*

Hopeful for?

… *winks more* 

Oh. I get it. Hmph!


Alright guys, Tautog here with another weekly roundup.

A lot of the team’s energy is currently on logistics and on navy foods at the moment. Zero has suffered a significant hard-drive failure. We’re working on rescuing our materials at the moment. Sorry if I sound terse. I’m a little worried. I think everything’s alright, but we’ll see.

I just feel really bad for Zero who has to scramble extra hard to get everything up and running again. In either case, here’s a revised schedule of release.

  • Navy foods book to be released first week of August – it’s gone to print already and it’s very cute.
  • 2016 preorder up sometimes soon (trademark) – the book is ready but logistics, logistics, logistics.
  • In lieu of releasing Vol. 3 at Comiket we’ll be releasing a preview book of Vol. 3 at Comiket instead. Sorry, folks, but November is doing his best.

Cold Waters is a fun game though. Go give it a shot if you like subsims!
