7 Charlie Meanings in the Military


As said earlier, the Charlie military term has 7 different meanings. We will explore each of them in detail now! Are you ready? Let’s go!

1. A Soviet Navy’s submarine classified as the “Charlie” class

The Soviet Navy operates nuclear-powered cruise missile submarines that are classified as Charlie I or II. These submarines are decommissioned and used for Oniks missile tests. The Charlie I and II submarines were designed by Gorky’s Lazurit Central Design Bureau.

The Charlie I is about 95m or 312ft in length and was 4,000 tons when surfaced and 4,900 tons when submerged. Its beam was 10m or 32ft-and-10in with an 8m (338ft) draught and propulsion including a pressurized water reactor that powered two steam turbines delivering 11,185 kW. The recorded speeds were 37km/hr or 23mph when surfaced and 44km/h or 28mph when submerged. Arnaments include:

  • 21-inch tubes with a max load of 12 torpedoes
  • 2 kt anti-ship nuclear torpedoes and 2 Tsakra
  • 15 kt anti-submarine torpedoes
  • 8x P-70 anti-ship missiles
  • 24 AMD-1000 ground mines

The Charlie I was launched back in 1967 at the Gorky’s Krasnoye Sormovo inland shipyard, as part of Project 670 Skat. They were designed for surprise attacks on aircraft carriers and other high-value surface targets. There were 11 Charlie 1 class submarines used between 1964 and 1971.

The Charlie II is an upgraded version at 103m or 338ft in length, surfacing with 4,3000 tons and submerging 5,100 tons. Its beam and draught were also 10m and 8m, respectively. Although the propulsion and speeds are the same, Charlie II complements less than Charlie I by 2. The Charlie II is equipped with 8x P-120 anti-ship missiles instead of 8x P-70 anti-ship missiles. There were 6 Charlie 2 class submarines used between 1975 and 1980.

The last Charlie ceased activities in 1994 and one class unit was leased to the Indian Navy in 1988 for 3 years to gain experience in nuclear submarine operations.

2. A military slang for the Viet Cong and North Vietnamese soldiers during the Vietnam War

During the Vietnam War, American soldiers referred to the Viet Cong as V-C or Victor Charlie, wherein “Victor” and “Charlie” are letters in the military’s NATO phonetic alphabet. The name “Charlie” was used to call communist forces in general,

Simply put, it is a shortened nickname so that American soldiers did not have to spell out “Viet Cong”. If the entire “Viet Cong” name was spelled out, it would have been:

V: Victor

I: India

E: Echo

T: Tango

C: Charlie

O: Oscar

N: November

G: Golf

Very long, right? V.C to Victor Charlie was much easier and convenient. Later, it became just Charlie, and sometimes, even Charles.

Fun Fact: Charlie’s first appearance with this meaning was in a Saigon newspaper (1956).

3. The letter “C” in the NATO phonetic alphabet used in the radiotelephone.

The NATO phonetic alphabet, also widely known as the International Radiotelephony Alphabet, includes 26 codewords assigned to each letter in the alphabet. The purpose of this was to make sure similar words or letters would not be ambiguous, particularly during radio or telephone communications.

Here is a chart of the NATO phonetic alphabet.

A: Alfa or Alpha N: November
B: Bravo O: Oscar
C: Charlie P: Papa
D: Delta Q: Quebec
E: Echo R: Romeo
F: Foxtrot S: Sierra
G: Golf T: Tango
H: Hotel U: Uniform
I: India V: Victor
J: Juliett W: Whiskey
K: Kilo X: X-Ray
L: Lima Y: Yankee
M: Mike Z: Zulu

As you can see, Charlie stands for “C” in this alphabet system.

Note: “Delta” is sometimes “Data”, “Dixie”, or “David”. “Whiskey” is replaced by “Washington” or “White” in Muslim countries, and “India” is “Italy” or “Indigo” in Pakistan.

4. A radiospeak that means “Continue Mission” during missions and operations

In the military, you will surely hear the term “Charlie Mike”, which means “Continue Mission” when translated from the NATO phonetic alphabet. Typically, you will catch this term while communicating through the radio during missions and operations.

5. A radiospeak that means “Loud & Clear” during radio checks

Another radiospeak in the military that involves the term “Charlie” is “Lima Charlie”. Based on the NATO phonetic alphabet it is referring to “L” and “C”, short for “loud and clear”. This is typically used to respond to a radio check.

6. The third threat level above “normal” for military installations

There are 4 threat levels that are above “normal” for U.S military installations. The 4 threat levels are THREATCON ALPHA, THRETCON BRAVO, THREATCON CHARLIE, and THREATCON DELTA, which are low, medium, high, and critical, in the same order.

Hence, in this regard, “Charlie” is a high-level threat. This is when there is an incident or a form of terrorist activity recognized by intelligence.

7. A phonetic expression for a clusterfuck

Another term that you will likely hear in the military is “Charlie Foxtrot”, which refers to a clusterfuck. If you search “clusterfucks” in the dictionary, you will not get any definitions. But do not worry. We will define it for you here. “Clusterfucks” is a military jargon that means:

  • An unorganized gathering of people
  • A minor or major mishaps leading to an almighty failure
  • A lot/a group of clueless people in a single space
  • A screwed-up event of the situation on many levels
  • A screwed-up caused by many inept officers

Through the radio, military personnel will say “Charlie Foxtrot” because of the primary use of the NATO phonetic alphabet, rather than “clusterfucks”.


To recap, Charlie has 7 different meanings in the military. Hopefully, now, you no longer need to ponder about “What does Charlie mean in the military?”
