lol

you are backpedaling already?

incredible

In another 10 years, US carriers will probably have production facilities to print spare parts and possibly entire engines. The Ford-class certainly has the power for it. The main thing is waiting for metal printers to get to the point where they can print the pressure vessels and turbine blades.

support this ludicrous statement first before you try to say that "3d printing" (which is a retarded name for prototyping and sintering) is used

obviously laser sintering exists it's like twice your age

too bad it's only used for realtively small and minor parts like fuel injection nozzles

nothing serious

you ahve zero idea how engines are made much less what sintering is actually capable of though i guess so it's to be expected

but this is public knowledge which youre too lazy to support with real facts i guess instead you have the same view of manufacturing that a journalist who writes clickbait articles online has

except you probably spent less time researching it because the journo did all the "hard work" on that front

You want to try saying all that again without acting like a prima donna jackass, or are we done with this conversation?

[Velkanika]

Well then, don't expect me to pay attention to anything you post until your attitude improves. Most of the regulars here probably have at least an AA degree, so acting like you're in middle school isn't really getting you anywhere.

[Velkanika]

Is it still possible for naval forces to surrender in the modern day? If so, by what means would they express this to the enemy?

Radio. All modern naval forces monitor the Guard frequencies, and will hear a request for a cease fire and terms immediately.

[Velkanika]

Soode, you've been drafted. Go make an OP.

[Venice-Slovenia1]

how is the sovermenny class for a standard fleet vessel for an area like the mediterrenean and adriatic sea?

[Verdiga]

We have Arleigh Burke class destroyers as our main destroyers, albeit slightly modified.

We also have some US submarines for naval defense.

[Verdiga]

Is it better to use an LCAC over a traditional landing craft?

[Versail]

Can anyone point me towards a fairly cheap design for an aircraft/helicopter carrier?

[Versail]

Can anyone point me towards a fairly cheap design for an aircraft/helicopter carrier?

Cheep and Aircraft carrier are two different things.

HOWEVER

You could always attach a ton of barges, put plywood on top, weld 'em together and tow them with a tugboat.
Would work for both requests

When I said cheap I meant not cheap but not something that will break the bank.

[Versail]

Tanks with missiles. Anything with missiles. Lots of missile. Or just two or three of these: DF-21. Chinese Anti-Aircraft Carrier missile

Again, this ship doesn't travel alone, and it's literally surrounded by carrier groups on top of its own escorts. I mean, feel free to concentrate solely on the SD, while the 2,000-3,000 other warships and their associated aircraft wings intercept or jam your missiles and then turn your defenses into ruin.

Uhh big navy ya got there.

[Vespalia]

Don't think too much about ships planetside. But hey, why not try one?
...Vespalia's colonies rely on one key element for their defense from orbital bombardment and planetary invasion, the ballistic missile submarine. In the 7,000 years that have passed since their inception, their creature comforts, test depths, hull strength, and anti-submarine countermeasures have only improved. (The ASW ability less so than the other components, though.) But at their heart, their basic function remains unchanged: the ability to launch missiles with planet-rounding ranges. These have changed somewhat in the past 7,000 years.
Originally the Guardian-class submarine was capable of launching twelve Fletcher A9B SLBMs. Its' modern replacement, the S4 Sentinel V-class missile submarine, can fire thirty E83 Icarus* AEVMs** and twenty-four E18 Wrath SLBMs from its' twenty-seven missile pods. The Icarus AEVM is capable of knocking a Vespalian Space Command Diplomat-class light frigate's engines out, if it can evade the Diplomat's barrage of interceptor missiles and point-defense laserfire. Due to this limitation, many Sentinel Vs are required to engage a single target or series of targets. The E18 Wrath is largely included to allow the Sentinel V to support post-invasion defensive operations with nuclear firepower if necessary; the warhead of the missile can be interchanged between chemical-explosive conventional, plasma-electrochemical, fission, thermonuclear and full fusion options, of which five of each are available aboard the submarine for a total of 25 different warheads. The Wrath missile is also capable of secondary fire as an antispacecraft weapon as well, though its' capabilities as such are limited to engaging extremely low-orbiting and suborbital targets. The Icarus is able to hit targets in geosynchronous orbit of a Delia-sized*** planet, and has a maximum range of approximately 220,000 km. The Wrath missile has a range of approximately 40,000 km, able to hit anything within one half-circumference of Delia. The Sentinel V-class submarine can also deploy up to twenty Outrigger-class torpedoes, and is equipped with S9/H lasers for anti-torpedo defense.
Vespalian Space Command Army forces oversee all planetary surface defense, including naval operations, under Unified Planetary Defensive Command authority and UPDC protocols state that a "standard" fleet of Sentinel V submarines would comprise 411 vehicles. Sentinel Vs are in the modern day semiautonomous vehicles. This means that they can be piloted and crewed by humans; the maximum capacity is 148 people, though only 30 of them can be crewmembers at maximum. Of course, semiautonomy also means the Sentinel V ballistic missile submarine is more often than not under the control of an artificial intelligence which regulates the behavior of all of its' computer systems under some orders issued from UPDC as part of a swarm or attack squadron which may comprise up to 50 submarines. They collectively share information and coordinate their actions to fulfill all parameters to the best of their ability.
Sentinel V submarines are manufactured by a variety of plants in the Inner Colonies of Vespalia and on Delia in Vespalia itself, owned by the Vespalian Navy. It operates 840 submarines on Delia of this class. Elsewhere, Sentinel Vs fall under the aforementioned command of the VSC Army.
Sentinel V submarines may also deploy up to four Barracuda-class submersible troop deployment craft carrying five soldiers each, for a maximum of 20 soldiers. They are generally elite Army or Colonial Defense Force troops equipped for submarine insertion onto a target.

[Vilatania]

But, the UNE's largest vessel is the mothership, known as Hypercane. It has a length of 180,000 km. However, this ship is more of a planet then a military vessel, as its designer added habitable space for civilian populations to prevent it from being used as a weapon.

The mothership is actually by no means the largest ship, only the largest one with weapons. The largest class of vessel is actually the Sunbreathers, which are 10,000,000 km long, and are used for constructing planets, gathering resources, and manufacturing star ships by the millions. These ships are extremely important, without them the UNE would likely collapse.

How does the UNE compensate for the gravitational affect that such large(and presumably heavy) vessels would have on the stellar bodies around them?

«Us zombies are not known for being capable of operating a naval vessel at all, let alone maintaining a navy. However, a handful of scholars have observed so-called 'zombie barges' - masses of us zombies arranging ourselves into a buoyant boat-like mass and sailing hundreds of miles to new landmasses, similar to how some species of fire ant will construct a living raft from their own bodies in order to endure a flood.»

[Viritica]

The Viritican Navy currently has three Liberator-class supercarriers.

Aside from that, we also have a wide variety of other warships.

[Viritica]

What would a carrier strike group be composed of?

[Viritica]

Missile dreadnought sounds like a good idea for a ship.

[Vitaphone Racing]

My ships use an all-electric system; no steam. It's safer, requires less maintenance, and without a steam plant you have more room to have your reactor-plant be larger - which is a necessity to have enough photovoltaics and thermocouples for it to be at all efficient.

Why are you using thermoelectric generators on your ship? You aren't going to get enough power of of them to run a warship. The only practical method for getting all the power you need to run a warship is via a steam turbine.

To add stats (because everybody looooooves stats), the efficiency of a thermoelectric generator is typically 7% while the efficiency of a steam turbine is about 60%. Enough said.

I'll also point out that photovoltaics on a ship will likely add no more than a whole 5 kw. Solar-powered anything-that-moves usually is more trouble than it's worth.

Hence why my ships are more along the lines of PMT, since modern thermocouples and thermoelectric generators can't be asked for more than about 15%.

Yes, but the PMT card doesn't explain how you're going to get a respectable amount of power from these generators. Even in the furthest forseeable future, they don't have a likely efficiency rating beyond 20% which still makes them a poor choice as a method of power propulsion.

Personally, I can't see why you wouldn't use a steam turbine which has just as much potential for improvement, and is already many times more efficient.

Plus, if you have one aspect of your ship that's outrageously PMT (which a usefully efficient thermoelectric system would be) and the rest of it's relatively mundane, it isn't going to make any sense.

Also, not solar. The photovoltaics are to help get energy from the reactor.

Hence they aren't photovoltaics but thermophotovoltaics. I don't want to sound like I'm nitpicking, but the difference between the two is pretty substantial and not to be confused with each other.

[Vitaphone Racing]

The entire purpose is to cut out the engine-room. So many parts. So much maintenance. So many people you don't have to have. You can get more power overall if you cut the engine room. So much care goes into those things. It's an old convention we can do without.

The space you save from doing this will be easily made up by using thermoelectric generators, you'll need a lot more to make up for their exceptionally low output. If anything, you're saving the jobs of a few mechanics, and I mean a few because naval turbines and transmissions are about as reliable as they get.

If anything, you're saving the jobs of a few mechanics, and I mean a few because naval turbines and transmissions are about as reliable as they get.

That's not entirely true. Keep in mind the engines are being moved externally to the vessels in this case and you're removing the need for condensers. At the same time, you need fewer pieces of equipment in your Primary, so again, saving space there.
In the end, you'll end up encroaching on about 20% of that space you saved getting rid of the engine room, but it actually still saves space.
Getting rid of the internal main engines, condensers, and reduction gears really make a difference in the space-issue.

It is entirely true, though. Even with a steam turbine, you can still create a purely electric transmission system so you don't need to focus on that. The thing is you need between 5 and 6 times the amount of thermoelectric generators to match the output of the steam turbine. That's between 500% and 600% more space being taken up by reactors alone. In the end, the space saving of removing the turbine and the heat exchanger counts for very little, but costs a lot more and requires far more intensive maintenance regimes when the ship is in dock. TPV cells degrade really fast.

If you were designing a luxury yacht, it might be worth it. But you're designing an aircraft carrier.

I simply put it at "photovoltaics," because two types are being used in this core design; There are thermophotovoltaics, yes, but along the walls of the RC there are also gamma-photovoltaics with doped-polymer shielding in front of them to bring the gammas into the absorption window for the photovoltaic cells, and again behind them to bring the remaining gammas into the window for the actual shielding.

I get that, but "photovoltaics" refers exclusively to the cells which operate in the visible light spectrum. Not only are people going to go "lolwut" reading about photovoltaics in a core, but thermophotovoltaics and "gamma-photovoltaics with doped-polymer shielding" sounds cooler too. It's a win-win.

And the 20% efficiency rating isn't considered to be too far off. Close enough for my stuff to still be considered early-PMT. Granted, that's purely speculative, but it's something that several companies are considering close enough to go for the sans-steam-plant-design.

The 20% efficiency rating is only foreseeable with the stirling engine protoypes; and using these would sort of defeat the purpose of not using a steam turbine because you've now got even more moving parts and even more space being consumed. Other TPV cells will run close but as production models probably won't top more than 15%, even with thermocoupling as well.

[Vitaphone Racing]

That's if you actually care.
Some people just want something to show off, they don't actually care about going into a Roleplay.

Thats kinda my point. Show off what exactly, their ability to hotlink to lots of pics?

Or maybe... maybe just... people post pictures of warships here because they are the visual representations of what ships they actually use in roleplays and they don't post stat blocks because they don't understand the basics of ship building and don't want to learn at this point in time? This isn't a boy's club, this thread is open for everyone to post their nation's warships here and there are no limits on how much information you can and cannot post. Please refrain from being snarky in order to preserve the image of these threads and those who post in them.

Designed a destroyer, any criticisms or suggestions for improvements?

Ostvind class destroyer

The Ostvind class destroyer was the primary destroyer of the Vloskovian Navy during the 1930's and 1940's. 20 were built from 1933 until 1939. Armed with six 120mm guns and eight 20" torpedo tubes, it was one of the most powerful destroyers in Europe at the time, although it was lacking in anti-aircraft armament, having only four 20mm AA guns. During a 1942-3 refit, they were upgraded by installing a radar system and more AA guns, including two Bofors 40mm mounts in place of the "B" turret.
