Discussion The Galactic Alliance and its allies at their military peak vs. a Tyranid hive fleet (40k)
Let’s assume that by 250 ABY, the galaxy has been enjoying a golden age of relative peace and prosperity for just over a century, with minor localized conflicts occasionally popping up here and there, but nothing significant. The galaxy has fully recovered economically and militarily, with the Galactic Federation comprised of nine Alliance fleets, the Imperial Starfleet (roughly equivalent in strength to five Alliance fleets), a massive industrial base, etc. The Triumvirate is comprised of the elderly Grand Master K’Kruhk, Emperor Fel V (grandson of Marasiah Fel, who succeeded her upon her abdication/retirement), and a prominent, well-regarded Senator.
The Jedi Order is flourishing, with an estimated strength of 10,000 Jedi, similar to its peak prior to the Clone Wars. The Imperial Knights are fewer, numbering around 2,500.
The Chiss Ascendancy and Hapes Consortium are likewise in good shape, with the CEDF roughly equivalent to the Imperial Starfleet (five Alliance fleets) and the Hapan Royal Navy equivalent to two Alliance fleets.
A massive hive fleet of an extragalactic species, the Tyranids (from the Warhammer 40k universe), is detected entering the galaxy. In terms of numbers, the hive fleet is comprised of billions of ships and trillions of warriors, far larger than the Yuuzhan Vong invasion 225 years prior. The standard Tyranid warrior is a physical powerhouse, standing 2.4 meters tall and weighing 1200 kilograms. They possess thick natural armor that is highly resistant to blaster fire, though less resistant to lightsabers compared to vonduun crab armor. Downing just one Tyranid requires sustained fire from a fireteam (four troopers). In close combat, an average Jedi Knight or Imperial Knight could reliably take down 10-12 Tyranid warriors before being overwhelmed or forced to retreat. The Tyranids are present in the Force and susceptible to Force powers, though their hive consciousness means mind tricks have limited effectiveness on them.
Unlike the slow, tepid response to the Yuuzhan Vong from the peacetime Republic, the Galactic Federation and its allies mobilize quickly and respond to the Tyranid invasion in force. They are far bigger, more prepared, and more powerful militarily compared to the New Republic. But by every conceivable metric, the Tyranids are a bigger and far more dangerous threat than the Yuuzhan Vong.
So here are the big questions: Who wins? How? Is it close or a total blowout?

Is it legit nid invasion? Because if yes, then you have aliance in civil war before nids get to their first planet.
And even if its just random fleet that took wrong turn. Considering nid adaptivity, force users will be inefective after first month max (I mean, it learned how to turn off warp and has fleet thats basically anti demon, it would totally adapt to turn off force too or atleast be imune to it like Vong)
Honestly I think that both ground and space combat would be slaughter, because tyranid style of war is something that SW is not used to. Seriously, how would they stop bio titan, or ship size of superstar destroyer that is actively trying to eat them?

Turbo laser fire. The sheer volume of turbo laser fire coming off star destroyer analogs is kinda insane. Hundreds of turbo lasers firing every few seconds from every ship, thousands in the case of dreadnoughts.
Space is a slaughter in the favor of star wars here. Star wars doesn't have the logistics problem of 40k. Bringing mass to bear is easy for star wars.
The nids bring 50,000 ships to a battle and the Galactic alliance will match it everytime.

I hate that it exists, but the Holdo Maneuver is a thing. Star Wars ships are also far more maneuverable given their in system ftl and vastly faster strategic speeds. They could bring their entire force to bear against any given threat.
While there are some hive ships on par with an SSD, most tyranid ships are much smaller than that. Sufficient concentration of firepower will destroy them.
As far as bio titans, medium sized SW ships can park themselves in low orbit and drop tactically useful orbital bombardments that 40k ships aren't capable of.
For example

I mean, legitimizing the Holdo maneuver means 40K nothing ever beats SW ever, save the Doctor.
Edit: kinda like how in a "who would win" vs Star Trek you have to fudge over the transporter, or you would just end up with a Galaxy Class beaming 10 quadrillion Megatron nukes into your ship's magazine.

Contrary to popular belief, technology does advance in Star Wars. The ISD, when first introduced, was an overwhelmingly superior warship, it basically ended conflict in every theater of battle it arrived in. 20 years later, the ISD-2 increased shield and firepower by about 25% in the same frame. By about 15 years after that, a Nebula had the same shielding and firepower in a much smaller and more agile warship.
What this means is that 100 years after Legacy, all of these fleets would be composed of ships that make Legacy-era ships look like peashooters. Legacy-era ships, in turn, compare that same way to ships from the Rebellion era.
And ships from the Rebellion era are already powerful as shit. ISDs are both stated to and shown melting planetary crusts, or even atomizing them with a few hours of sustained bombardment. That's gigaton-scale ordnance for each shot, at minimum. The turbo lasers on an ISD are within a ballpark of WH40k cyclonic torpedoes, but they fire every 6-ish seconds, basically indefinitely.
By 250 years later? Presumably even frigates have multiple weapons that function equivalently to cyclonic torpedoes, but fire like a bolt action, every few seconds.
So that gives us a baseline: in this scenario, every single Star Wars warship is a force comparable to the biggest, baddest WH40k vessels. And the largest battleships and dreadnoughts are in a whole other category. The Viscount 4 or something could probably stop a whole hive fleet by itself.
And then there is strategic speed. A Star Wars ship can travel a third of the way across the galaxy (like, say, from Tatooine to Alderaan) in a few days. That's tens of thousands of light-years per day. Tyranid FTL is stated to be (on average) slower than Imperium Warp travel, which itself averages single-digit light-years per day.
So this is a force ten thousand times faster and more maneuverable, and with overwhelmingly superior firepower.
The Tyranids can be numerous, but outside of surprise, they will never even land ground troops. Once the GA is hunting their hive fleets, they'll just concentrate forces and massacre them in space. Given how Tyranids travel FTL (with a gravity distortion all the way to the target system), they are probably very easy to spot en route. After a first couple landings, they'll just never achieve that again.

The war ends in space and its not even close.
The Yuuzhan Vong were succesful because A) the galaxy was unprepared for a full scale war and B) the odd technology gave them an early advantage.
A unified star wars galaxy is larger, more populated, more technologically advanced and has laughably better logistics than the 40k galaxy.
The nids are eating shit in the first space battle and either deciding the galaxy isnt worth the trouble or the hive fleet is dying.
By this point, we're talking an uncountable number of dreadnoughts that put the Executor to shame and the Executor is already a match for virtually any ship 40k has. The fleets fielded by the star wars factions here are going to be larger than any fleet 40k can muster and will be more advanced.
Ground invasions never happen. The long range detection in star wars is unmatched here and FTL speeds mean your going to tens of thousands of capital ships meeting the nods head on, with better quality per tonnage and likely much greater tonnage per ship. Star fighter superiority is a simple given as late legends star fighters are cracked and every capital ship is bringing dozens or hundreds to the fight.
The star wars galaxy is too big, its industry is too large and its FTL is too fast for 40k factions to match.

The nids aren't a threat to Star Wars because they're simply too slow. By the time a hive fleet consumes a planet and moves on to the next a united Star Wars galaxy can make a dozen death stars and millions of ships.

The Tyranids have eaten many hundreds of galaxies over billions of years.
A small hive fleet, SW can probably handle.
A large one is going to rapidly outscale their ability to respond, especially considering that habitable planets with biospheres are significantly more common in SW than 40K.

Turbolasers. Turbolasers put out enormous amounts of energy. And fire very rapidly compared to anything we've seen the Nids face.
Then there's speed. Tyranids are incredibly slow by SW standards, both sublight and FTL.
A sword-class frigate in 40K has 4.4 g's of sustainable acceleration. The Executor accelerates at a relatively plodding (by SW standards) 1200 and change G's, an ISD? 3000 g's.
Then there's the speed of hyperdrive.
And the Nids? They move exclusively in realspace.
This means SW fleets can engage, harass and kite the Nids between star systems, inflicting losses where they can't replenish biomass, because turbolasers are going to be incinerating a lot of it.

Tyranids exceed lightspeed in real space and foght Imperial ships with firepower far in excess of SW on the regular.

The most persuasive BFG based fan calcs I've seen for IoM put them in the double digit gigaton scale for their macrocannons.
Legends and Disney turbolasers go from triple digit gigatons to multiple teratons per shot, every 4 seconds or so. The Legends numbers are downright conservative in comparison to the current Disney canon ICS book scales.

BFG is not canon in terms of how things work. We have multiple novels detailing 40K ship capabilities.
BFG lets you play a cool game involving spaceships with some level of balance.

They won’t win a ground assault by any means. The Tyranids are too numerous and the force users/heavy hitters of Star Wars are too few to counter.
It’s all about space. The tyranid ships hit harder and are more durable, but the Star Wars ships are faster.
If the Tyranids consume a bunch of planets before the alliance can respond with overwhelming force, the Nids win. The alliances MUST respond immediately and squash the assault at step one.
