The Space Battleship Yamato, seeing as you said “Battleship”.
I recommended that show to my anime watching daughter and she laughed at me
Didn’t the last Star Wars movie have deathstar laser mounted to battleships and they were all going to shoot one planet somewhere in the galaxy - and they started with Corrisont which was on the other side of the galaxy. Would that be considered longest range?
Mixing up a couple movies. The planet-killer fleet never got to use their main guns. Starkiller Base did destroy planets in another star system, but none of them was Coruscant. The main planet was commonly mistaken for Coruscant, but that’s due to bad communication with the audience. The laser splitting to hit individual planets in the same system being visible with the naked eye from anywhere in the galaxy also indicates Abrams has no idea how distance works.
I can’t remember what it was, but there was a game or a book I played/read where the lasers on battleships were infinite and there’s an argument over why the gunner needed to be precise.
Not Mass Effect; not the “Sir Issac Newton is the deadliest son of a bitch in the galaxy” line. Similar thing, but that game world used ballistics, not energy weapons IIRC.
I know it’s not on a ship but if Deathstar counts, this should be pretty close.
I want to introduce you guys to a bunch of Colony Lasers in Gundam universe.
I’m not totally sure but want the Death Star always moved to pretty much be in orbit before firing? It was powerful but not necessarily looking range.
The Behemoth from the Expanse Series had a laser with a range of literal light years.
Granted, it was a comm laser, but they did weaponize it at one point.
Even if we assume that the beam had a solar-system sized diameter after 4 ly, a weaponized output should still be in ship-killer range after an AE or five.
Ultimately, the weapon was never fired (and would have melted half the ship if it ever were).
