Realistically, when do you think the first viable space "cruiser", "destroyer", etc would be viable and/or be made?

Like EVE or Star Wars/Trek on a smaller scale due to the constraints of Earth's resources.

imo the iss counts as a cruiser because i would say it technically cruising and i bet any of the astronauts in there could drive it by another space vehicle and pick up hot dates w/ it

As soon as humanity collectively stops being afraid of nuclear power and we can start building nuclear thermal rockets. Until then, we're stuck piddling around a sphere a hundred million kilometers in diameter except for whenever we throw a probe towards the outer planets.

once there's war in space you're going to want to be in the smallest and fastest thing possible. there's a reason made-up energy shields factor so heavily into sci-fi wars.

i disagree. as soon as we start to construct vehicles in space out of space foraged materials, they can suddenly become large, almost unbounded. the most sensible result is some sort of borg-cube like assortment of manufactured and captured habitats. current status quo makes it feel like the most likely outcome is some sort of drifter hellscape like titan ae rather than star trek fully automated space communism, but who knows.

There certainly aren't any physics reasons you can't build a big spaceship. They were going to build an entire fleet of the things during the Cold War, because of general Cold War insanity.

https://www.thespacereview.com/article/2714/1

quote:

In late 1959, Captain Mixon laid out the evidence for General Thomas Power, the commander in chief of SAC, and obviously convinced him. On January 21, 1961, General Power signed a SAC requirement for a “Strategic Earth Orbital Base” (SEOB) based on the Orion propulsion system and roughly following the space force deployment concept. The SEOB would be “capable of accurate weapon delivery” to “include the capability to attack other aerospace vehicles or bodies of the solar system occupied by an enemy.” The SEOB would also be able to orbit “extremely heavy useful payloads” on the order of 5,000 tons.

These are the ship roles they were planning:

quote:

STATIONED IN SPACE

Command/Control
Strategic Weapon Delivery ("Bomber")
Surveillance-reconnaissance
Space Defense
Orbit Logistics
Lunar Base Support
Space Rescue and Recovery
Satellite Support
R&D Laboratory

STATIONED ON THE SURFACE

Emergency Command/Control
Space Interceptor
Damage Assessment
Space Rescue and Recovery
Satellite Support



Some extremely pro classified concept art:



It might actually have been cool and good because there's no military reason to build a giant space fleet in the foreseeable future, so it would funnel military funds into something militarily pointless while opening up the way to the solar system. There were also civilian applications for Orion, of course. They wanted to fly to Mars and Jupiter and such.

Is there a size limitation to something like a nuclear thermal rocket? Or even a nuclear reactor?

If there's ever space combat I think it's gonna look a lot like the Expanse. Whole buncha missiles and miniguns and boarding. Except the ships are still gonna look like the ISS or something I bet.

I only think that because there's no reason at all to build sleek looking stuff since aerodynamics don't matter. It'd be more cost effective to just build ugly rear end poo poo than go to the trouble of building everything in a pleasing sleek hull.

Plus then you can do poo poo like decouple parts that have been boarded

I would imagine space combat would mainly consist of a whole bunch of floating around and waiting and then a few tense seconds of battle during which everything gets destroyed ridiculously fast.

Not so sure a military ship would look like ISS though since it would probably also need some type of armour and isolation to survive smaller skirmishes. A bigger ship is also less likely to be set adrift when impacted, so while the other guy here who said fighters will need to be small and fast, that'd be offset by their ridiculous vulnerability.

This is firmly in the sci-fi realm, but I remember a book that featured a space-combat scene where they made small jumps with the ship and their pursuers would jump mines ahead of them into the spots they thought they would be, which was terrifying to me.

Which is why it wouldn't really make sense to have military ships in space, at least not the way we think of them. The reality is that the better method in space would just be to stay really far away from everyone else, as getting anything like armor into space is just to "expensive" (in terms of energy cost). You'd need a pretty massive leap forward in getting stuff off of earth in order to have armored ships. Or I guess you could do space mining, but the logistics of that seem pretty far off. Even then you have the problem of adding mass, which means you just need that much more energy to move stuff. Space is a real bitch.

I always thought John Harris's illustrations of military space ships looked like a reasonable compromise between "ugly and practical" and "cool".

So like all military combat, except now we're all floating.

Sounds about right.

A space warship (or a large civilian ship for that matter) probably wouldn't look a lot like the ISS because if you have something that's worth calling a space warship it kinda implies there are things in space to fight wars over which implies we probably don't need it to be launched in tiny self-contained modules on small rockets. It's an extreme level of modularity that's not necessarily the best choice for most things.

With 3d printing tech coming along pretty well, ship printers could probably be put in space in a relatively soon timeframe I would guess. I think the hard part is still getting a concerted effort to have any type of permanent space scaffolding set up, with zero g mining required. Who knows how long that's going to take to get off the ground. After that, most of the military ship sizes would probably be fighter sized, since that's all you need to take out satellites, missiles, and other fighters.

I think maybe a cruiser would be needed once we became interplanetary, since you would need something to threaten other populations and would need the firepower and ability to hit ground targets with force.

And if you gaze long into an abyss, you will say `look, no ring.`

Pretty much the only thing in space worth shooting is other people's satellites. There's also the potential for bombardment of the surface of earth from orbit. So early military spacecraft will probably be some sort of "space plane" that can gently caress with opponents satellites and a bunch of satellites capable of launching kinetic penetrators, conventional explosives or nukes. So nothing new.

What if we shoot lasers from our battlecruiser and miss the enemy? Where do the lasers go? They've gotta hit something, right?
