Both Article 110 and Article 119 can arise from negligent conduct, but they address different harms. Article 110 Improper Hazarding of Vessel punishes willfully or negligently causing a vessel to be hazarded or stranded, focusing on the danger to the ship itself. Article 119 Involuntary Manslaughter punishes negligently causing another person’s death. When a maritime accident kills crew members, both articles might apply: one for endangering the vessel, one for killing its occupants.
The Harm Distinction
Article 110 Improper Hazarding of Vessel focuses on:
The vessel itself
Stranding, grounding, or otherwise hazarding the ship
Damage to military property (the vessel)
Navigation and seamanship failures
Article 119 Involuntary Manslaughter focuses on:
Human life
Death of a person
The ultimate harm: loss of life
Both can result from the same negligent conduct, but they measure different consequences.
Different Protected Interests
Article 110 protects:
Military vessels as valuable assets
Naval operational capability
Government property worth millions or billions
The mission capability the vessel represents
Article 119 protects:
Human life
The lives of crew members and passengers
The sanctity of life above property
While both are important, the law treats taking human life as qualitatively different from damaging property.
Article 110: Hazarding Elements
Improper hazarding requires:
A vessel of the armed forces. Military ship, boat, or aircraft (aircraft can be “vessels” for this purpose).
Hazarding or suffering to be hazarded. Putting the vessel in danger of damage, loss, or destruction.
Through willful or negligent action. Either intentionally or through negligence in navigation, command, or operation.
By a person subject to the article. Typically the commanding officer, navigator, or others responsible for the vessel’s operation.
This applies specifically to those responsible for the vessel’s safe operation.
Article 119: Manslaughter Elements
Involuntary manslaughter requires:
Death of another person. Someone actually died.
Caused by the accused’s conduct. The death resulted from the accused’s actions.
Through culpable negligence. Negligence so gross it shows wanton disregard for human life.
OR during an unlawful act. Death occurred while committing a non-felony offense.
The focus is entirely on the death and its cause.
When Both Apply
Maritime disasters often implicate both articles:
Scenario: A commanding officer, through negligent navigation, causes the ship to collide with another vessel. The ship is severely damaged, and three crew members are killed.
Article 110: The CO’s negligence hazarded the vessel (the collision and damage)
Article 119: The CO’s negligence caused deaths of crew members
Two different charges for two different harms from the same negligent conduct.
The Negligence Standard
For Article 110, negligence means:
Failure to exercise proper care in navigation or operation
Deviation from accepted maritime standards
Mistakes that a competent officer should not make
The standard is professional competence in seamanship.
For Article 119, culpable negligence means:
More than simple negligence
Gross negligence showing wanton disregard for life
Conduct so careless it approaches recklessness
The standard is higher than ordinary negligence.
This means some conduct might satisfy Article 110’s negligence standard without meeting Article 119’s higher culpable negligence standard. Negligent navigation that hazards a vessel isn’t necessarily culpably negligent if no one dies, but if the same negligence causes death, the higher standard is evaluated.
Typical Fact Patterns
Clear Article 110 (hazarding) without death:
A navigator falls asleep on watch, and the ship runs aground on a charted reef. The ship is damaged but no one is killed. Hazarding the vessel through negligence.
A commanding officer fails to verify weather reports and takes the vessel into a severe storm that damages the ship but causes no deaths. Hazarding through negligent operation.
Clear Article 119 (manslaughter) without vessel:
A service member ashore negligently operates a vehicle and kills a pedestrian. Involuntary manslaughter with no vessel involvement.
A service member’s negligent handling of equipment kills a colleague. Involuntary manslaughter on land.
Both articles apply:
A ship’s officer of the deck fails to maintain proper lookout, the vessel collides with another ship, two sailors are killed, and both vessels are severely damaged. Article 110 for the hazarding; Article 119 for the deaths.
Command Responsibility
Article 110 often applies to those in command:
Commanding officers are responsible for their vessels
Officers of the deck are responsible during their watches
Navigators are responsible for safe navigation
Engineers may be responsible for propulsion-related casualties
Command responsibility means senior personnel face Article 110 charges for vessel casualties, while Article 119 might apply to anyone whose negligence causes death.
Punishment Comparison
Article 110 (Improper Hazarding):
Willfully hazarding: dishonorable discharge, forfeiture of all pay and allowances, confinement for 5 years (or more in war)
Negligently hazarding: bad-conduct discharge, forfeiture of all pay and allowances, confinement for 2 years
Article 119 (Involuntary Manslaughter):
Dishonorable discharge, forfeiture of all pay and allowances, confinement for 10 years
Manslaughter carries heavier maximum punishment because taking life is more serious than damaging property.
The Aircraft Question
Article 110 applies to aircraft:
Aircraft are “vessels” for purposes of this article
Negligent operation that hazards an aircraft is covered
Crashes due to pilot error can be Article 110 violations
If crew or passengers die, Article 119 also applies
Aviation accidents parallel maritime accidents in this analysis.
Investigation Process
Major accidents trigger extensive investigation:
Safety investigations determine technical causes
Command investigations examine accountability
Criminal investigations consider UCMJ charges
Both articles are considered when vessels are hazarded and people die
The investigation determines whether negligence occurred and what charges are appropriate.
Defenses
For Article 110:
No negligence occurred (proper procedures followed)
The hazard wasn’t caused by the accused’s conduct
Mechanical failure beyond the accused’s control
Unforeseen circumstances (hidden hazards, sudden weather)
Another person was responsible for the navigation error
For Article 119:
The accused’s conduct didn’t cause the death
The negligence wasn’t “culpable” (just ordinary negligence)
The death resulted from unforeseeable circumstances
The accused wasn’t responsible for the conduct that caused death
Career Implications
Maritime casualties often end careers:
Commanding officers are typically relieved after significant casualties
Careers are rarely recovered after major vessel losses
Even without criminal conviction administrative consequences are severe
Criminal conviction ends any hope of continued service
The “captain goes down with the ship” principle reflects the absolute responsibility commanders bear.
Frequently Asked Questions
If a ship is damaged by my negligence but no one is hurt, can I still face serious charges?
Yes. Article 110 applies to hazarding vessels regardless of whether anyone is injured or killed. Naval vessels are enormously expensive assets, and even minor groundings can cause millions in damage. Commanders and responsible officers have been court-martialed for vessel casualties even without injuries. The charge is about the danger to and damage of the vessel, not about harm to people. If people are also killed, Article 119 adds to the charges, but Article 110 stands alone as a serious offense for endangering military vessels.
What’s the difference between simple negligence and “culpable negligence” for manslaughter purposes?
Simple negligence is failure to exercise reasonable care. Culpable negligence is gross negligence so severe it shows wanton disregard for human life. For Article 110 hazarding, ordinary negligence suffices. For Article 119 manslaughter, the negligence must be culpable (much more serious). A navigation error might be negligent but not culpably so. Repeated failures, ignoring obvious warnings, or extreme carelessness elevate negligence to culpable. The distinction often determines whether someone faces property-related charges (hazarding) or homicide charges (manslaughter). Courts examine the severity of the deviation from proper conduct and whether the risk of death was obvious.
Can enlisted personnel be charged with improper hazarding of vessel, or is it just officers?
Article 110 can apply to anyone whose negligence hazards a vessel, not just officers. While commanding officers bear ultimate responsibility, others can also be charged if their specific negligence caused the casualty. An enlisted helmsman who falls asleep and causes a grounding could face Article 110 charges. An enlisted engineer whose negligence causes a propulsion casualty that results in the ship running aground could be charged. The key is whether the person had responsibility for the operation that went wrong. Typically, the more senior the position, the greater the expectation of proper conduct, but enlisted personnel with operational duties can be charged for hazarding.
