What’s a “Skimmer” in the Navy?

Ever hear a sailor on a submarine casually refer to another ship as a “skimmer”? It’s not an official term, but a nickname born from the tight-knit culture of submariners. In the quiet, deep-diving world beneath the waves, surface vessels—whether destroyers, carriers, or supply ships—are often called skimmers. Why? Because, from a submariner’s perspective, those ships never truly dive; they just skim along the surface.

This bit of naval slang carries a subtle edge—a mix of camaraderie and quiet pride. Submariners operate in a unique, isolated environment, where silence and stealth are paramount. To them, life on a surface ship might seem louder, more visible, and frankly, less demanding in certain ways. Calling those ships “skimmers” is a way of distinguishing their own world—one of pressure hulls, sonar pings, and months underwater—from the more visible fleet above.

It’s not always meant disrespectfully. Often, it’s just shorthand, a tribal in-joke among those who wear the submarine insignia. But it does reflect a deeper truth: life aboard a sub is unlike any other in the Navy. The crew shares a bond forged by confinement, danger, and the sheer uniqueness of their mission. So when a submariner says “skimmer,” they’re not just describing a ship—they’re marking a boundary between two very different ways of serving at sea.

And while surface crews might roll their eyes at the term, they’ve got their own nicknames too. The banter is part of the culture—a long-standing tradition of ribbing that, at its core, underscores the pride each group takes in their service. After all, whether you’re diving deep or skimming the surface, one thing’s certain: you’re still part of the fleet.
