The Missile Knows Where It Is
Also known as: The Missile Copypasta · Missile Guidance for Dummies
"The Missile Knows Where It Is" is a copypasta and audio meme based on a deliberately circular explanation of missile guidance systems, originally printed in a 1997 Air Force newsletter1. The passage describes how a missile navigates by "subtracting where it is from where it isn't," looping through increasingly confusing logic that sounds technical but reads like a parody of bureaucratic jargon. First shared online around 2003, it gained traction through YouTube uploads and musical remixes before a major resurgence on Twitch in 20193.
Overview
The meme centers on a passage that attempts to explain how a missile's guidance system works, but does so in the most circular, redundant way imaginable. The key lines read:
> "The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is, whichever is greater, it obtains a difference, or deviation."
The text spirals deeper into self-referential logic from there, with phrases like "arriving at a position where it wasn't, but is now" that make the reader feel like they're trapped in a feedback loop3. An accompanying audio recording features a deadpan male voice reading the passage with complete seriousness, which only makes it funnier. The humor comes from the tension between the official, authoritative tone and the fact that the explanation explains absolutely nothing to anyone who doesn't already understand inertial navigation1.
The text first appeared in the December 1997 issue of the Association of Air Force Missileers newsletter, on page 5, under the title "GLCM GUIDANCE SYSTEM"2. It was submitted by Colonel (Ret) George Grill, who had worked with General Dynamics at Greenham Common Air Base in England1. The newsletter prefaced the text with the note that "it may not be the first time you have seen this," suggesting the joke had already been circulating within military circles before its print publication1.
The passage describes the guidance system of the BGM-109G Ground Launched Cruise Missile (GLCM), which used a combination of inertial navigation and terrain contour mapping, known as TERCOM1. The original newsletter text ends with a single word: "Simple." This punchline strongly suggests the whole thing was written as an inside joke among guidance, navigation, and control (GNC) engineers poking fun at how impenetrable their field sounds to outsiders1.

How to Use This Meme
The Missile copypasta works in a few common ways:
As copypasta: Drop the full text (or a recognizable excerpt like "The missile knows where it is at all times. It knows this because it knows where it isn't.") into comment sections, Discord servers, or chat when someone asks for an overly simple explanation and you want to give them the opposite. It's especially popular as a response to "explain X simply" prompts.
As a remix: Take the audio clip and layer it over a beat or instrumental track. The deadpan delivery pairs well with hard-hitting instrumentals, creating a comedic contrast. The "Still D.R.E." version set the template.
As a reference: Quote or paraphrase the circular logic structure when mocking bureaucratic language, overly technical documentation, or any explanation that manages to say nothing while sounding authoritative.
On Twitch: Submit remixes through media-sharing features on livestreams. The meme typically gets big reactions from both streamers and chat.
Cultural Impact
Fun Facts
The newsletter text was submitted by a retired Colonel who worked at Greenham Common, a UK base best known for women's peace camps protesting nuclear missiles in the 1980s.
The passage describes the BGM-109G GLCM, a now-decommissioned nuclear cruise missile that was deployed in Europe during the Cold War.
The original newsletter note suggests the joke predates its 1997 print publication, meaning it may have been circulating among defense contractors and military personnel for years before anyone put it on paper.
GNC (Guidance, Navigation, and Control) is considered one of the most highly protected and specialized fields in aerospace engineering, which makes the existence of this joke even funnier.
Derivatives & Variations
"Still D.R.E." remix:
The most widely circulated version, setting the missile audio over Dr. Dre's instrumental. Multiple versions exist on YouTube, with Krasniye's 2017 upload among the most viewed[3].
Twitch media-share remixes:
Various musical remixes created specifically for Twitch stream media-sharing segments, which drove the 2019 resurgence[3].
Portfolio-length student video:
Inimicu's 2007 video showing a student listening to the audio for a school assignment, the first known YouTube upload of the meme[3].
