Documenting the Attack on the Pentagon on 9/11

Oral Histories Reference Guide

Most of the oral histories were given by Navy personnel who had been in the service for many years.  As a result, the oral histories are full of terms and references that may be foreign to anyone who is unfamiliar with Navy life.  This guide provides descriptions and definitions for the terms and references that appear most commonly in the oral histories.

The oral histories are from Navy Archives collection AR/670 DET 206: Documenting the Attack on the Pentagon on 9/11.  For more information on the collection and a complete list of the oral histories from the collection that have been released to the public, visit the AR/670 main collection page.

Navy Command Center (NCC): The central hub for tracking and monitoring global naval operations, the NCC was located on the first deck of the Pentagon.  The main entrance of the NCC was located at 1D457. The NCC spanned the light well between the D and C Rings, meaning a ceiling had been erected in the light well to create a continuous space on the first deck and the outer wall of the NCC offices was the outer wall of the C Ring.  On a normal workday, between 50 and 70 people were on duty in the NCC.  On the morning of 11 September, 42 Navy personnel working in the NCC lost their lives. The losses included military and civilian personnel, as well as contractors.  Of the survivors, some escaped relatively unscathed, while others would require significant medial atttention.

The personnel that worked in the NCC served in different commands that all shared the NCC spaces.  Here are a few of the commands that shared the NCC spaces.

NCC Offices: CNO IP - Chief of Naval Operations Intelligence Plot 
NCC Offices: METOC - Meteorology and Oceanography Command
NCC Offices: N323 - OPNAV Interagency Support Ops
NCC Offices: N513 - OPNAV Strategy and Concepts

Navy Lingo

Navy lingo, including shipboard terms, become part of a sailor's everyday vocabulary over time, so sailors often continue using the lingo even when on shore and in civilian life.

The individuals who transcribed the oral histories were not fluent in Navy lingo.  As such, the spellings were based mostly on pronunciation.  Listed here are the terms by their commonly accepted spellings.  Alternate spellings that appear in the oral histories are listed in the definitions.   

Bulkhead: Wall

Deck: Floor, Level

Flag Officers: In the U.S. Navy, a flag officer is any officer at or above the rank of O-7 Rear Admiral (Lower Half).  In the oral histories, the directors of the OPNAV N Code offices were often referred to as a group as "Flag Officers."   

Geedunk: also Gedunk or Gedonk; A term referring to snacks and the location where the snacks are sold.

Hot Wash: also Hotwash; A debrief following a meeting  

JP: also J-P, Jet, or any of the previous followed by a number or letter; Jet Fuel

Khaki(s): The Khaki uniform is reserved for Officers (O-1 and above) and Chief Petty Officers (E-7 and above). For this reason, “Khakis” and “Khaki Uniforms” are often used as shorthand to reference these personnel.

Ladder: A catchall term used to refer to stairs of any angle, as well as actual ladders. When it appears in the oral histories, the term is referencing stairs.

N Code: A shorthand term used to describe the general organization of administrative offices within the U.S. Navy.  The OPNAV N Code structure at the time of 9/11 is listed above.  That organization would have been used by other commands.  For example, U.S. Navy Third Fleet administrative offices are organized by the same N Code structure.  "N Code" can also be used as shorthand to describe the admirals or other leaders who direct the N Code offices.  For example, in the oral histories, "N Codes" was used to refer to the two and three star admirals who were serving as the directors of the OPNAV N Code offices on the day of the attack.

Overhead: Ceiling

Pooka: also Puka; Cubicle

Three Stars: A shorthand term used to describe the Vice Admirals (three stars) who were serving as the directors of the OPNAV N Code offices.
