Would Nuclear Weapons be as destructive in ship to ship space combat, as they are on the ground in an atmosphere?

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Chances are there isnt enough air to make a significant difference and any ship large enough to have enough air would have air lock systems as a safety net.
Right, but the ship itself would allow the shockwave, metal is still matter for vibrations to follow.
The shock wave needs a medium (air) to travel through. So if the bomb was touching a ship, it would certainly transfer kinetic energy, but if there was any space (not air) between them, there is still no shockwave for the ship to feel.
A railgun would be far more effective for transfering kinetic energy and it's munitions would likely be cheaper
How about a railgun with a nuclear payload? Breach the hull and the nuke would work again
With a hull breach the atmosphere within leaks out and I doubt there would be enough oxygen in the ship to really help with detonation. Maybe some self sealing projectile with a nuclear tip but really any traditional explosive would work fine in that case as the ship would act as a sealed canister
I think you overestimate how fast the atmosphere would leak out, or underestimate how fast a nuclear blast goes off. You could detonate the nuke before air really has a chance to start leaving behind the wake of the projectile moving at Mach 12 or whatever. The hole left behind i don't think would change how the explosion worked inside the ship.
How would oxygen help with a nuclear detonation?
A shockwave can travel along the solid structure itself as the medium. Any ship that is actually directly hit would be vaporized. It's just the whole point of nuke is not needing a direct hit. I doubt any realistic space vessel with anything even remotely similar to plausible near future technology could survive a direct hit from even a moderately sized conventional explosive.
Yeah, it takes incredible amounts of energy just to move unarmored ships slowly around our own solar system.
Seems like adding armor would make them so heavy and slow that they wouldn't be worth using.
Yeah that's why any reasonable hard sci-fi has to rely on highly advanced fusion or speculative energy technologies
That would have to be a big ship to feel a shock wave without being consumed by the ball of plasma
Where would that come from? According to a posted article in this thread thermal energy can't transfer either unless by direct connection and radiation would be the biggest factor, with increasing size compared to on the surface due to lack of atmosphere "attenuating" the distance it travels.
If we're talking about a direct hit, the radiation is going to be substantial
True, but it's not a ball of plasma.
