torpedos...usually just any should do the trick...though i tend to use the second tier torpedo(1000dmg should be the one)
torpedos in general have a really large explosion radius...which you usually only notice if theyre fired on fighters especially ones flying in formation or standing ready for an ambush

my missiles for taking out a single wing of fighters are ARLM or hornets

i dont think the other missiles have such a huge explosion radius...other long range missile might have but i did not test
