United States Department of Defense directive 5230.16, Nuclear Accident and Incident Public Affairs (PA) Guidance,[1]Chairman Joint Chiefs of Staff Manual 3150.03B Joint Reporting Structure Event and Incident Reporting, and the United States Air Force Operation Reporting System, as set out in Air Force Instruction 10-206[2] detail a number of terms for reporting nuclear incidents internally and externally (including in press releases). They are used by the United States of America, and are neither NATO nor global standards.
Pinnacle is a Chairman of the Joint Chiefs of Staff OPREP-3 (Operational Event/Incident Report) reporting flagword used in the United States National Command Authority structure. The term "Pinnacle" denotes an incident of interest to the Major Commands, Department of Defense and National Command Authority, in that it:
Generates a higher level of military action
Causes a national reaction
Affects international relationships
Causes immediate widespread coverage in news media
Is clearly against the national interest
Affects current national policy
All of the following reporting terms are classified Pinnacle, with the exception of Bent Spear, Faded Giant and Dull Sword. AFI 10-206 notes that the flagword Pinnacle may be added to Bent SpearorFaded Giant to expedite reporting to the National Military Command Center (NMCC).[3]
Bent Spear refers to incidents involving nuclear weapons, warheads, components or vehicles transporting nuclear material that are of significant interest but are not categorized as Pinnacle – NucflashorPinnacle – Broken Arrow. Bent Spear incidents include violations or breaches of handling and security regulations.
An example of a Bent Spear incident occurred on the August 2007 flight of a B-52 bomber from Minot AFBtoBarksdale AFB which mistakenly carried six cruise missiles with live nuclear warheads.[4]
Broken Arrow refers to an accidental event that involves nuclear weapons, warheads or components that does not create a risk of nuclear war. These include:
Unofficially, the Defense Atomic Support Agency (now known as the Defense Threat Reduction Agency (DTRA)) has detailed hundreds of "Broken Arrow" incidents.[7]
Nucflash refers to detonation or possible detonation of a nuclear weapon which creates a risk of an outbreak of nuclear war. Events which may be classified Nucflash include:
Accidental, unauthorized, or unexplained nuclear detonation or possible detonation.
Accidental or unauthorized launch of a nuclear-armed or nuclear-capable missile in the direction of, or having the capability to reach, another nuclear-capable country.
Unauthorized flight of, or deviation from an approved flight plan by, a nuclear-armed or nuclear-capable aircraft with the capability to penetrate the airspace of another nuclear-capable country.
Detection of unidentified objects by a missile warning system or interference (experienced by such a system or related communications) that appears threatening and could create a risk of nuclear war.
This term is a report that has the highest precedence in the OPREP-3 reporting structure. All other reporting terms such as Broken Arrow, Empty Quiver, etc., while very important, are secondary to this report.[3]
Faded Giant refers to an event involving a military nuclear reactor or other radiological accident not involving nuclear weapons,[1] such as the SL-1 reactor explosion.
Dull Sword refers to reports of minor incidents involving nuclear weapons, components or systems, or which could impair their deployments. This could include actions involving vehicles capable of carrying nuclear weapons but with no nuclear weapons on board at the time of the accident. This also is used in reports of damage or deficiencies with equipment, tools, or diagnostic testers that are designed for use on nuclear weapons or the nuclear weapon release systems of nuclear-capable aircraft.[citation needed]
