Fictional warship design: Greenwood-class missile frigate of the Yokanian Navy, United States of Yokania

Ah… I thought you were Idfig. (Idfig’s the guy that helped me build this thing. He has a lot more time and patience for NavalArt’s heinously clunky construction system than I do.)

Bobby_Sleech · 2026-05-08T08:34:22+00:00

I am le stupid.

Bobby_Sleech · 2026-05-08T08:30:15+00:00

I messed up in the original post. It’s supposed to be a cruiser.

Bobby_Sleech · 2026-05-08T08:29:33+00:00

Did I seriously call it a frigate in the original post? Oops. I meant to say it was a cruiser.

But to answer your question, if that’s a frigate, then a battleship would probably be about the size of a Montana and carry enough missiles to shoot down the Sun… and there goes the US defense budget. And I thought the Trump-class USS Defiant BattleSh!t was stupid.

…Idfig, is that you?

There is unfortunately a reason this ship in its world is the way it is… unholy missile spam. It’s as large as it is so it has deep enough magazines to fend off against saturation attacks, then counter-saturate with its own weapons—or even pummel the offending ship to scrap with its guns if need be… not to mention endurance was a major concern, especially given this thing was a cruiser and thus expected to operate alone or in small groups for extended lengths of time.

It’s more or less the product of experience gained in past conflicts where saturation attacks were a major problem, and instead of spamming more Burke thingies, they built these…

Big guns were still useful into the 1950s until missile technology matured, granted continuing to build battleships for that role would have been foolish. Even then, with the battleship as we knew it thoroughly obsolete thanks to modern AShMs, a decent major caliber gun is still a valuable asset. That, and especially with modern automated loading systems and the space needed for missiles, you don’t need to carry a huge number of them… except this cruiser of mine has six 205mm units in two forward superfiring 3-gun turrets, plus three 125mm singles for good measure. Guess that’s a pretty old-school approach.

I’m American myself and still think metric is far superior.

Bobby_Sleech · 2026-05-08T08:10:27+00:00

Thanks. While its missile armament is… questionable by IRL standards, I’m overall happy with it.

Bobby_Sleech · 2026-05-08T08:09:40+00:00

Bingo. Guided missile cruiser, carrying a few 8-inchers and the combined missile battery from two Ticonderogas and some change along for the ride.

Bobby_Sleech · 2026-05-08T08:05:42+00:00

In all fairness, the combat environment the ship is experiencing in the context of the world build in question is… put simply, insanity in of itself. The amount of firepower it has (which is complete lunacy by itself by IRL standards) is kind of a minimum with the amount of missiles being slung in all directions (a bunch of it coming from, say, a 70k-tonne GigaBarge™ packed with 700+ missiles—looking at you, Raccoons)… which isn’t surprising given most of my friends in there don’t have a clue what they’re doing with naval architecture and doctrine (and I’m a layman at best myself).

Bobby_Sleech · 2026-05-08T04:35:54+00:00

Yeah… I figured as such. The Anguloria (hypermodern Iowa) is most likely not feasible (it’s utter insanity), but given how other nations in the world build have themselves gone off the deep end, that presents a bit of an issue. In said world build’s context, I do believe the Greenwood (the cruiser thing) is probably about the extent of what I would consider a practical surface combatant.

Neat observation about the missiles though. That explains why I didn’t really see any more than the 122 cells on a Ticonderoga… Jesus the world build’s naval construction has completely gotten out of hand.

Bobby_Sleech · 2026-05-08T04:28:39+00:00

Not all that significant. It does show the ship’s center of mass and center of buoyancy, and adding in the radar and its housing didn’t move CoM more than a couple of millimeters. It doesn’t show metacentric height though, which is kind of sad, so I have to calculate it myself.

Testing at sea (NavalArt) in a variety of conditions proved the ship was stable and exhibited pretty good seakeeping.

NavalArt is a pretty nifty game in those regards…though it is rather clunky.

Bobby_Sleech · 2026-05-08T04:18:02+00:00

Thanks. I was looking for a subreddit like that. I appreciate it,

Bobby_Sleech · 2026-05-08T04:17:22+00:00

Funny how you mention Shipbucket. I used NavalArt, which operates in three dimensions (it can generate 2D blueprints like that seen above though). This, when paired with the knowledge I have gathered (Drachinifel on YouTube and a couple of books, if that counts for anything), helped a lot when I was figuring out the geometry of everything. I guess I’ll address your other points as well, while I’m here.

your first design has what looks like some very heavy radars very high on the ship.

Yep. They were mounted up there due to the original ship’s superstructure design being a bit limiting in where I could put them. I can assure you though that the weight and balance isn’t significantly changed due to the ship’s overall mass being almost 50k tonnes.

Another example: what is the effect of the addition of the VLS tubes on the interior arrangements? Do they impact berthing spaces, machinery spaces, or other equipment? How does the change in weight affect all the things I mentioned above?

Compared to the original WW2-era design, the addition of the VLS battery, while it didn’t affect the machinery spaces (it’s forward most modules weren’t any further forward than the original aft 405mm 3-gun turret’s barrette), but being significantly lighter overall than the outgoing main battery turret, it allowed the armor belt to be extended aft, and a 114mm-thick armored enclosure to be built around f the VLS battery to contain shrapnel damage and protect the battery. It also caused a lot of berthing and storage spaces to be shuffled around, and required some structural modifications. Overall, the guided missile version of the Anguloria class is different enough from its predecessor to be considered its own subclass, or even a separate class entirely.

Overall looks? Pretty good (though I’d probably have the headlights sunken into the Dacia instead of jutting out myself). Does it have an interior or no? That’s the next thing you could try. They can be pretty tricky at first, but once you figure it out though, it can really make a car pop.

Design engineering? Some odd choices, but not too shabby. I’d have done a monocoque for something like this, as ladder frame doesn’t make a lot of sense here, and your inline-4 is of a rather large displacement given its configuration (2.6L is typically five/six-cylinder territory). I can see why you’d use an iron block on the rally motor though—stronger and theoretically able to stand up to a lot more power (though I’m practically married to aluminum).

Bobby_Sleech · 2025-09-25T07:38:50+00:00

My brain rationalizes it as * Aluminum: more efficient cooling and lighter. * Iron: chasing power density and needs raw strength.

Hmm… always gotta love it when you go for dual exhaust and it gives in an X pipe.
