Nah, a sunbeam. (Courtesy of E.E. "Doc" Smith, Second Stage Lensmen, First serialized in Astounding," Nov 1941-Feb 1942.)
Smith was the "trope-maker" for much of modern space-opera & SF. And as his stories went on, the scope of combat and forces involved just kept getting bigger. The Death Star is barely a capital ship by the standards of later Lensmen books, where a task force will regularly involve hundreds of immense ships, plantary masses worth of antimatter, and squadrons of armed and mobile planets. ("Starkiller Base" eat your heart out.) By the very end, exotic-matter planets were being used as ammunition.
In the Xeelee Sequence humanity uses a neutron star as a missile to try and attack the Xeelee Ring - which is quite big (millions of light years across).
