Frank R. Paul's Mechanized Planet Weapons, Amazing Stories 1930s

Electromagnetic death-ray warfare between mechanized artificial planets dominates this explosive interior illustration. A central glowing orb — bristling with antenna arrays, equatorial rings, and crackling lightning bolts — fires needle-like energy beams across a star-filled void at other armored spherical worldships. Smaller planetoid vessels and rocky terrain ground the cosmic scale. Paul's signature cross-hatching and radial burst energy effects define the scene, depicting a future of weaponized artificial worlds locked in interplanetary combat.
