"Conspiracy theories are big because they're comforting. Any conspiracy is infinitely less multiplex than the real deal, which is multiplex to the point of being unknowable."
- William Gibson

From Triplanetary (1934) by “Doc” Smith:

“As if contemptuous of any weapons the lifeboat might wield, the mother ship simply defended herself from the attacking beams, in much the same fashion as a wildcat mother wards off the claws and teeth of her spitting, snarling kitten who is resenting a touch of needed maternal discipline.“

Another example, from Seed of the Arctic Ice, a 1939 story by H.G. Winter:

Ken turned on her full twenty-four knots, zoomed above the dark bulk of the slower mother ship, whose light-beams flashed across him for a second, and then straightened out in a long, slight-angled dive after the great black bodies ahead.

From Rescue Party (1947) by Arthur C. Clark:

Across the vision screen two slim project les dived towards the looming mass of Earth. For a few miles they traveled together: then they separated, one vanishing abruptly as it entered the shadow of the planet.

Slowly the huge mother ship, with its thousand times greater mass, descended after them into the raging storms that already were tearing down the deserted cities of Man.
