Ceres-class Missile Battleship

spaceship =>

(description & fiction under the break!)

Video Description

Several views of a large, long, and slightly bulky Terran warship in space. The ship has repeating triangle motifs in with various paneled textures throughout. Near the pointed front the nameplate of the ship is visible, reading 'CNS Temeraire'. The long front hull has a flat section on the top, covered in massive missile launch bays. Amidships, several armor plates, painted bright red with the Jovian Eagle in gold, protect the armored hab rings and a series of tubes. Aft, the radiators glow brightly as the engine burns hot. Embedded heat pipes run from the tip of the engine to the radiators

The first view is of the ship from above and in front, showing a dramatic angle. Several 'running lights' blink down the length as navigation lights flash

The second view is located to the side, looking forward, again showing the various lights

The third view is focused on the engine, showing it powering on to 100% thrust, then beyond. As it powers on the heat pipes glow in sequence

The fourth and final view repeats the engine power on sequence but from further, allowing the viewer to also see the coolant vents venting coolant

Excerpt from History of Pre-Domestication Terran Warships (3rd Revision), §685.8: Late Terran Accord & Pacification Program Era Battleships (Guided Projectile), Eltrin Yne, Forty-Seventh Bloom, xe/xem, Elly Yne, Twenty-Sixth Floret, et al.

Designed in 2521 CE (33 BT) by a consortium of Jovian shipbuilding corporations and first commissioned in 2526, the Ceres-class missile battleship was envisioned as a platform to launch massed missile strikes against enemy fleets while providing enhanced point defense and electronic warfare. At 750 meters in length and nearly 100 meters at its widest extent, this class represented one of the largest mass-produced spaceframes fielded by the Cosmic Navy.

Over the course of its service history, the class had numerous revisions. Most notably, the type-3 revision in 2539 (2521-CERES-III) which added coolant vents ahead of the hab rings, reducing their size in the process. The vents were positioned forward of the hab rings to expel hot coolant from over-driven point defense domes and electronic warfare equipment rather than the main engines, though they had a limited ability to expel engine coolant in extreme emergencies. These coolant vents essentially functioned as expendable liquid droplet radiators, which may have led to the development of more practical liquid radiators, had domestication been delayed. (See also §359, Speculation on Terran Shipcraft Development)

While there were no major engagements which featured a Ceres functioning in this intended role, classified TCN documents obtained after the fall of Terra stated that one of the primary goals of the class was to counter contemporary corporate navies, which largely consisted of small anti-piracy vessels, should a coalition of corporations ever come into direct conflict with the Accord.

However, the most significant hostile force that the Accord encountered prior to pacification were various pirate flotillas, which would generally consist of smaller, older, and less militarized vessels. While in a direct engagement a Ceres-class or other contemporary Accord capital ships would easily destroy such vessels, smaller ships were quite capable of outmaneuvering and escaping their would-be-predators.

At the start of the Terran Pacification program, there were 157 Ceres-class vessels active. After the signing of the treaty, only a handful of these ships refused armistice, as the amount of logistical support that the Ceres required to function effectively and the implausibility of that support without the Terran core sectors dissuaded overt feralism. Several dozen of the surviving vessels now serve as museum ships across Terran Protectorate space.

From Alt National Park Service in n FB:

tl;dr:

DOGE accessed all those systems - IRS, Social Security, DHS, every office in the U.S. - not to promote “efficiency”, but to gather and control our electronic lives so they can ruin us if we step out of line in any way. Or if they just feel like it.

Alt National Park Service:

“DOGE has quietly transformed into something far more sinister — not a system for streamlining government, but one designed for surveillance, control, and targeting. And no one’s talking about it. So we’re going to spill the tea.

From the beginning, DOGE’s true mission has been about data �� collecting massive amounts of personal information on Americans. Now, that data is being turned against immigrants.

At the center of this effort is Antonio Gracias, a longtime Elon Musk confidante. Though he holds no official government position, Gracias is leading a specialized DOGE task force focused on immigration. His team has embedded engineers and staff across nearly every corner of the Department of Homeland Security (DHS).

But it doesn’t stop there.

DOGE operatives have also been quietly placed inside other federal agencies like the Social Security Administration and the Department of Health and Human Services — agencies that store some of the most sensitive personal data in the country, including on immigrants.

DOGE engineers now working inside DHS include Kyle Schutt, Edward Coristine (nicknamed “Big Balls”), Mark Elez, Aram Moghaddassi, and Payton Rehling. They’ve built the technical foundation behind a sweeping plan to revoke, cancel visas, and rewire the entire asylum process.

One of the most disturbing aspects of this plan? Flagging immigrants as “deceased” in the Social Security system — effectively canceling their SSNs. Without a valid Social Security number, it becomes nearly impossible to open a bank account, get a job, or even apply for a loan. The goal? Make life so difficult that people “self-deport.”

And if you’re marked as dead in the Social Security system, good luck fixing it. There’s virtually no path back — it’s a bureaucratic black hole.

You might ask: why do immigrants, asylum seekers, or refugees even have Social Security numbers? Because anyone authorized to work in the U.S. legally is issued one. It’s not just for citizens. It’s essential for participating in modern life — jobs, housing, banking, taxes. Without it, you’re locked out of society.

Last week, this plan was finalized in a high-level White House meeting that included DHS Secretary Kristi Noem, Antonio Gracias, senior DOGE operatives, and top administration officials.

In recent weeks, the administration has moved aggressively to strip legal protections from hundreds of thousands of immigrants and international students — many of whom have been living and working in the U.S. legally for years.

At the core of this crackdown? Data.

DOGE has access to your SSN, your income, your political donations — and more. What was once sold as a tool for “government efficiency” has become something else entirely: a weaponized surveillance machine.

And if you think this ends with immigrants, think again.

Antonio Gracias has already used DOGE’s access to Social Security and state-level data to push voter fraud narratives during past elections. The system is in place. The precedent has been set. And average Americans should be concerned.”

[vaspider]

It seems like you might be having a bad day? That AITA post was a really lighthearted promo and faux links ala Rick Rolls are an established part of internet sillies. It wasn’t malicious and the subject they linked to is free.

You’re generally a more level headed person so I was surprised to see how aggressive you got. But based on your reaction the author is getting doxxed which does feel unfair given the nature of the post.

Okay, no. Absolutely not.

First of all: This is the last thing I'm saying about that post. Anybody trying to continue this conversation with me in any way after this response will be blocked.

We're not doing that nonsense up there. We're not doing the "Spider is responsible for someone else's behavior" thing. I've been very, very clear that I don't endorse harassment or doxxing, and I've also been very clear that I'm not responsible for what other people do. Saying, "I don't like deceptive links, and this has done the opposite of interesting me, it's upset me and made me not want to read this; heads-up, y'all, this isn't a legit AITA post," which is all I ever said, really, isn't in any way an incitement of doxxing or harassment, and it's absolutely shitty of you to try to lay that at my feet.

Are deceptive links (commonly called "RickRolls" even when they don't link to the Rick Astley video) a fun and hilarious part of internet culture? Not really, actually. Most links on the internet that don't lead to where they say they lead aren't fun and cheerful little "memes" (the post wasn't a meme, but we'll use the word the OP used) inviting people to read a free queer book: they're usually part of social engineering phishing campaigns.

What makes the original RickRoll sometimes acceptable is a) the fact that you immediately know you've been "got" because an Original RickRoll is unmistakable after the first time you experience it, b) the link serves as a punchline to a specific kind of internet joke, usually along the lines of "click this link for news that seems too good to be true," which reinforces the idea that you have to be careful about believing what you see online, and c) it's unique. It actually isn't funny, cute, or cool to put deceptive links up online, with the possible exception of a well-executed Original RickRoll. That's the entire point of why Original RickRolls work.

Deceptive linking is a behavior that is illegal in some jurisdictions & is also grounds for banning from a lot of sites, including, wait for it:

Deceptive or Fraudulent Links. Don't post deceptive or fraudulent links in your posts. This includes giving links misleading descriptions, putting the wrong “source” field in a post, setting misleading click-through links on images, or embedding links to interstitial or pop-up ads.

Tumblr.

Got that? It's actually against the fucking rules here. It's really, really clearly written in Tumblr's User Guidelines section of the Terms of Service. You know, the rules everybody is supposed to be following to be here?

So, no, I'm not "having a bad day," except that people keep being asshats to me for saying, "I don't think it's cool that you did this thing (that breaks the ToS on the site and uses a technique commonly used for spearphishing) to promote your book, actually," doubling down on it by trying to shame me by using the fact that it's a queer book as an emotional lever, and now I've got this ask both trying to make me responsible for other people's behavior and acting like me saying "hey, this isn't cool, and no, that response isn't cool either," and then blocking the person and moving on with my life is somehow not "levelheaded."

tl;dr:

Deceptive linking is against TOS, actually.

I'm not responsible for other people's bad behavior. I did not invite or incite that behavior. I just said "this thing you did isn't okay."

I have expressly disavowed doxxing and harassment for years, both because it's shit and because I've been a repeat victim of it.

How dare you, actually.

I blocked the OP after my second response. I'm not going to talk about this anymore. Anyone sending me any further asks about the subject whatsoever or attempting to continue this conversation with me in any way will simply be blocked.

Fuck's sake.

• Fokker D.XXI Fighter

The Fokker D.XXI fighter was designed in 1935 by Dutch aircraft manufacturer Fokker in response to requirements laid out by the Royal Netherlands East Indies Army Air Force (Militaire Luchtvaart van het Koninklijk Nederlands-Indisch Leger, ML-KNIL). The D.XXI was designed as an inexpensive, rugged, and compact fighter aircraft that would possess respectable performance for its era.

On November 14th, 1934, design proposals for a new fighter aircraft were submitted by Fokker to the Luchtvaartafdeling (Dutch Army Aviation Group). Fokker's design team, led by Erich Schatzki, and based at the firm's newly completed plant in the southern district of Amsterdam, had sought to incorporate and combine various new concepts and recent features from successful fighter aircraft, including the previous C.X and D.XVII aircraft. The proposed aircraft was a low-wing monoplane which adopted an entirely enclosed cockpit; initial design work had been conducted in cooperation with British engine manufacturer Rolls-Royce, and it had been originally envisaged that the type would be powered by a Rolls-Royce Kestrel IV. Projections of the aircraft's performance included a maximum speed of 420 km/h at an altitude of 4,350 meters, a range of 888 km, and an altitude ceiling of 10,000 meters. The planned armament included rifle-calibre machine guns or 20mm cannons, which were to be embedded into the wings and fuselage.

In early 1935, the Luchtvaartafdeling signed a contract for a single prototype of the proposed fighter to be constructed for an evaluation to be performed by the Royal Netherlands East Indies Army. This prototype, designated FD-322, which was powered by a single Bristol Mercury VI-S radial engine which drove a three-blade, two-pitch propeller, performed its maiden flight at Welschap Airfield, Eindhoven, on March 27th, 1936. According to aviation author G.H. Kamphuis, the prospects for series production of the new fighter looked doubtful shortly after the first flight was performed due to a high level change in Dutch defence policy; Minister for Foreign Affairs Hendrik Colijn informed the Ministry of War that, in response to the changing international situation, a higher priority would be placed on building up a substantial bomber capability over new fighter aircraft. In addition to the Luchtvaartafdeling's interest in a trainer aircraft, the service had also attached great importance to the concept of a heavily armed 'cruiser' aircraft capable of performing multiple mission types. Further doubts and confusion were added by the emergence of a competing aircraft proposal in the form of the Koolhoven F.K.58, which had also been designed by Ir. Schatzki. It was decided that the D.XXI and F.K.58 should participate in a series of comparative tests against one another, leading to the D.XXI prototype being dispatched to Soesterberg Air Base, Utrecht, in November 1936. However, head-to-head testing between the two types was delayed by the F.K.58, which did not perform its first flight until September 1938.

During 1937, the Dutch government gave funding and its approval for a limited expansion of the Army Aviation Group, which resulted in an order being placed for 36 Fokker D.XXI fighters, to be powered by the 830 h.p. Bristol Mercury VII or VIII engines. According to Kamphuis, Dutch interest in the D.XXI had been revived, in part, due to an examination of the first aircraft by an evaluation board, which itself had been conducted due to interest expressed by the Finnish Air Force, which itself would result in export sales being made to Finland. On July 20th, 1938, the first Luchtvaartafdeling D.XXI conducted its first flight, after which it participated in test flights prior to deliver to Soesterberg. On September 8th, 1939, the final aircraft of the first batch of 36 was delivered. Even as the domestic demand for the D.XXI was being questioned, the type had attracted the attention of a number of foreign governments. In 1937, the Finnish government decided to place an order for an initial batch of seven aircraft, further negotiations were also conducted towards the acquisition of a manufacturing license, under which Finland proceeded to domestically produce further aircraft as well. Throughout 1940 and 1941, the Finnish State Aircraft Factory set about reconditioning the aircraft that had been used in the Winter War for continued service; an additional 50 D.XXIs were ordered in 1941, which were powered by the Pratt & Whitney R-1535 Twin Wasp Junior engine, acquired via Sweden. The Danish government ordered a pair of D.XXI fighters along with arrangements for its own manufacturing license. The Danish D.XXI fighters were powered by a 645 h.p. Bristol Mercury VI-S radial and carried a Madsen 20 mm cannon under each wing. Ten aircraft were completed by the Royal Army Aircraft Factory in Copenhagen prior to the German invasion of Denmark in April 1940. The Second Spanish Republic also acquired a manufacturing license for the D.XXI. Reportedly, a total of 50 fuselages were manufactured on the Spanish production line; however, the Spanish plant in which the fighter was being produced was overrun by Nationalist forces before any of the Spanish-built aircraft were completed.

The Fokker D.XXI was a low-wing monoplane fighter aircraft. Following standard Fokker design practice of the period, it featured a welded steel tube fuselage that was largely covered by fabric, including the flight control surfaces; element forward of the trailing edges of the wings were covered by detachable aluminum panels instead. The wings were of a wooden construction, being composed of two box spars attached to ribs made of plywood. The aircraft was outfitted with a fixed spatted undercarriage with cantilever legs; braking was provided by independently-operated pedals using compressed air. The cockpit of the D.XXI was fully enclosed by a plexiglas hood featuring large sliding sections, and was entirely jettisonable in an emergency situation to enable pilots to bail out. Pilots were protected against turnover injuries by means of a pylon built into the structure of the aircraft set behind the seat. Fuel was housed in a 350-litre (77 imp gal) tank located aft of the engine. The main armament consisted of two pairs of 7.92mm M36 FN-Browning machine guns, one pair housed within the wings, carrying 300 rounds of ammunition each, and the other pair within the forward fuselage and shooting through the propeller blades, carrying 500 rounds each. Upon its entry to service in 1938, the D.XXI represented a significant leap forward for the Dutch Army Aviation Group, whose fighter force had until that time consisted of aging biplanes with open cockpits. The new Fokker quickly proved to be an extremely sturdy aircraft, being capable of attaining a speed of 700 km/h in a dive.

The Fokker D.XXI was first used in combat by the Finnish Air Force during the 1939–1940 Winter War between the Soviet Union and Finland. Upon the war's outbreak, a total of 41 aircraft were in Finnish service, all powered by the Mercury VIII engine. On December 1st, 1939, the D.XXI achieved its first victory with the shooting down of a Soviet Tupolev SB. The Fokker was evenly matched against the aircraft of the Soviet Air Force, and its rugged design with a radial engine and fixed undercarriage made it well suited for Finnish conditions. As the Winter War continued and newer models of Soviet fighters appeared, the Fokker D.XXI proved to be increasingly underpowered and too lightly armed to compete; plans to arm the Fokkers with 20 mm cannons were dropped, and only one fighter was armed with two 20 mm cannons and two 7.92 mm/.312 in machine guns. The conflict between Finland and the Soviet Union was resumed in the Continuation War (1941–1944), the D.XXI was again a key element of the Finnish Air Force. During the first air battle, six Mercury-engined D.XXIs shot down a pair of Soviet Ilyushin DB-3 bombers. Several Finnish Air Force pilots became fighter aces with the Fokker D.XXI.

Although the order by the ML-KNIL was cancelled, the Luchtvaartafdeling (Dutch Army Air Force before World War II) placed an order of 36 aircraft, which were all delivered in time to participate in the war against the Germans in May 1940. On May 10th, 1940, the day that Germany launched its invasion of the Netherlands, 28 D.XXIs were serviceable and ready for operations. That first day, six D.XXIs escorted a formation of Fokker T.V bombers to attack the Meuse bridges to hinder the German advance; they were intercepted by nine German Messerschmitt Bf 109s, and during the ensuing dogfight, one Bf 109 was shot down and two more damaged for the loss of one D.XXI and two T.Vs. That same day, a flight of D.XXIs intercepted and shot down 37 out of 55 inbound Junkers Ju 52 transports which had crossed the border during the early morning. Due to many aircraft becoming unserviceable as a result of battle damage after the first day, it was decided to regroup at Buiksloot, north of Amsterdam, on May 11th. For the following four days, missions out of Buiksloot were flown by D.XXIs flying in both solo and small formations to escort friendly units as well as in the search-and-destroy role. Sorties against the numerically superior German forces continued until the middle of May 14th, at which point news of the Dutch capitulation reached Buiksloot, upon which both the remaining aircraft and the airstrip were destroyed to prevent their use by the Germans. Out of the original force of 28 D.XXI aircraft, eight fighters had remained airworthy. The D.XXI, although much slower and more lightly armed than the Bf 109, performed surprisingly well in combat due to its manoeuvrability. It was also one of the few aircraft that could follow a Stuka bomber into its dive. Nonetheless, the numerical superiority of the Luftwaffe led to the destruction of most Luchtvaartafdeling D.XXI fighters during the campaign. The LVA (Netherlands Air Force) scored a total of 38 victories against the Luftwaffe during their struggle against the German juggernaut. 16 of those went to Fokker D.XXI pilots.

A Mercury-engine Finnish-built Fokker D.XXI, FR-110, is on display at the Finnish Air Force Museum, Jyväskylä, Finland. This is the highest scoring (10 victories) D.XXI airframe. It was the mount of Lt. Viktor Pyötsiä during the Winter War. In 2022, a flyable replica was completed at Hoogeveen Airport by veteran aircraft restorer Jack van Egmond. A number of original parts was used and the plane was built according to original Fokker build specifications as Jack van Egmond is in possession of 397 out of 416 Fokker blueprints.
