Greater than 5,000 American sailors and Marines aboard the plane provider USS Abraham Lincoln have spent over 250 consecutive days at sea, the longest stretch and not using a port name by a US provider within the trendy period.
A number of sailors have tried to leap overboard, in accordance with reviews by Navy Instances and Stars and Stripes, two publications that carefully cowl the US army. Households have instructed US lawmakers of crumbling morale, and one sailor’s spouse stated he had texted her that he “hopes he would not get up tomorrow”.
The disaster, unfolding because the US battle with Iran retains extending Lincoln’s deployment, has put into focus what months of confinement, movement, disrupted sleep and isolation really do to an individual.
What occurred on USS Abraham Lincoln
The Lincoln left San Diego on November 21, 2025, certain initially for the Pacific, earlier than it was redirected in direction of West Asia forward of the US-Israel battle towards Iran, in accordance with the Guardian and Al Jazeera.
The deployment was on account of finish in Could however has been prolonged repeatedly. The crew has had solely two days on land since then, in Guam in December 2025 and Oman in July 2026, the Guardian reported.
At a city corridor in San Diego final week, roughly 200 members of the family confronted appearing navy secretary Hung Cao and different officers, Stars and Stripes reported. One lady stated on the assembly the US Navy had “damaged belief between us and the management,” in accordance with The Guardian’s report of the city corridor.
Navy Instances individually reported that Annabelle Loma, the spouse of a sailor aboard the ship, stated her husband had tried to leap overboard after his deployment was prolonged. One other sailor’s wife, Al Jazeera reported, stated her husband had bodily stopped a shipmate from going over the facet.
CBS Information, citing two unnamed officers, reported {that a} sailor went overboard on August 3 and was recovered by helicopter, handled and moved off the ship. The circumstances stay underneath investigation, as per BBC.
The reviews triggered outrage within the US.
In line with The Guardian, President Donald Trump dismissed issues over deteriorating morale, claiming households weren’t apprehensive and calling the document deployment “not almost lengthy sufficient”. Addressing the crew’s prolonged time at sea, he stated, “That ship is shifting proper now, or very shortly, and it’s being changed with one other very comparable ship.”
Democratic senator Richard Blumenthal of Connecticut wrote to protection secretary Pete Hegseth citing “shortages of fundamental provides, water contamination, plumbing points, deteriorating psychological well being, deck security issues and disruptions within the mail system”. Senator Mark Kelly, a former naval officer and astronaut, known as the reviews of overboard makes an attempt “disturbing”. And Democratic Congressman Mike Levin of California described situations aboard as “moldy showers, damaged bathrooms, laundry down for weeks, lengthy stretches with no sizzling water, a meal that got here right down to half a cup of rice and two tortillas. No cleaning soap, deodorant, or toothpaste”.
Hegseth has pushed again, dismissing the primary wave of criticism over situations on the Lincoln in April as “extra pretend information”. This week, as the newest reviews emerged, he known as them “fully misrepresented”.

“We be sure each ship, each crew, each captain has every little thing we will present them at each single second,” he added.
The US Navy has given near-identical statements, saying it has “not recognized a rise in reported suicidal ideation or suicide makes an attempt aboard the ship”, and that medical, spiritual and mental-health assist is offered to the crew.
Sea insanity, in literature, and what Homer knew
Earlier than trendy navies began protecting incident logs, writers have been describing what stillness and confinement at sea might do to a thoughts. Samuel Taylor Coleridge’s The Rime of the Historical Mariner (1798), nonetheless taught in India’s Class 10 CBSE English syllabus, captures a ship becalmed and a crew unravelling:
“Day after day, day after day
We caught, nor breath nor movement.”
Herman Melville’s Moby-Dick (1851) additionally traced Captain Ahab’s psychological descent throughout an prolonged voyage, and the cabin boy Pip’s breakdown after being left adrift alone at sea.
However the theme is sufficiently old to predate Homer’s Odyssey, made ever extra well-known this yr with famed director Christopher Nolan releasing his star-studded Hollywood adaptation of the traditional Greek story.
Odyssey, which follows Odysseus’ decade-long, storm-battered journey residence after the Trojan Struggle, has been mined by students looking for info on what the epic may reveal about historical sailors’ expertise.
A 2017 peer-reviewed historical review in Frontiers in Neurology, by Doreen Huppert, Judy Benson and Thomas Brandt of the German Heart for Vertigo and Stability Issues in Munich, traced medical descriptions of movement illness from Homer’s time (roughly 800 BC) by way of to the late Roman interval.
The traditional Greeks, the authors discovered, already acknowledged that seasickness was a physiological response to unfamiliar movement, and that skilled sailors constructed up resistance to it over time, a phenomenon trendy science calls habituation.
A 2019 paper within the Cambridge classics journal Antichthon, by unbiased scholar Rupert Mann, argued that a number of episodes within the Odyssey monitor actual seafaring expertise slightly than pure invention. Mann pointed to the encounter with the ocean goddess Ino/Leukothea, who seems to Odysseus throughout a shipwreck to information him to security, as an early literary model of a phenomenon documented in trendy survival accounts: a sensed, guiding presence reported by individuals in excessive isolation and disaster.

This kind of an expertise is usually referred to elsewhere, in polar and mountaineering survival literature, because the “third man issue”.
Mann’s argument was that the Odyssey‘s narrative, desertion at pleasant ports, cautious navigation by way of a harmful strait, a sensed companion throughout a shipwreck, reads as oral custom constructed from what actual Bronze Age Mediterranean sailors would have really gone by way of.
What trendy science says
On land, the human mind will get a reasonably predictable stream of details about steadiness and movement. At sea, these indicators may be in battle. The eyes might register a level-horizon whereas the vestibular system feels the ship roll and pitch.
Over time, although, the nervous system can adapt on account of neuroplasticity: the mind’s capability to recalibrate itself to repeated expertise.
That adaptation can persist even after a sailor is again on land, in a dysfunction known as mal de debarquement syndrome (MdDS), a persistent sensation of rocking or swaying that, not like odd “land illness” doesn’t all the time fade inside days.
In a 2015 review revealed within the Annals of the New York Academy of Sciences, Dr Yoon-Hee Cha, a neurologist, described purposeful brain-imaging research of sufferers with persistent MdDS. These confirmed altered exercise within the entorhinal cortex, a area concerned in spatial processing, and the amygdala, linked to anxiousness and persistent stress. Sufferers additionally reported signs comparable to persistent fatigue, cognitive slowing and heightened sensitivity to visible movement.
Sleep, too, suffers at sea
Warships don’t run on a nine-to-five schedule. As an alternative, naval forces use watchkeeping to rotate shifts by way of the day and evening. This fixed shifting fragments sleep. Over time, that sleep deprivation builds up considerably.
A 2022 study within the Worldwide Journal of Environmental Analysis and Public Well being, led by Mikko Myllylä and colleagues, adopted 18 crew members aboard a Finnish navy patrol boat by way of two totally different watch schedules. The examine discovered that older sailors and people with longer naval service reported larger sleepiness, fatigue and stress responses on board, whereas sailors with larger bodily exercise and health ranges reported much less of all three.
That fatigue may be damaging over time.
A study by Olav Kjellevold Olsen and colleagues on the Royal Norwegian Naval Academy, revealed in Worldwide Maritime Well being in 2013, examined naval officers in rested and partially sleep-deprived states throughout a simulated maritime fight train. Sleep-deprived officers have been considerably worse at anticipating each ethical and tactical issues earlier than an operation started, the researchers discovered. This, they stated, was proof that misplaced sleep doesn’t simply make individuals drained, it degrades judgement.
A 2025 study within the journal Army Medication, analyzing 441 US Navy sailors, most of them aboard an plane provider, discovered that essentially the most distressing stressors have been loud noise, being unable to relaxation when wanted, and insufficient entry to psychological and bodily healthcare.
Confinement would not finish when the shift ends
Sailors on a deployed warship can’t go residence after a tough day. The ship is each their office and residence. They see the identical faces each day, and the skin world arrives solely by way of letters, calls and port visits.
A 2021 study in Frontiers in Psychiatry adopted 29 submariners on a nuclear-powered submarine patrol and located that temper and psychological functioning deteriorated over the course of the deployment no matter health ranges, although sailors who saved up common bodily exercise maintained steadier consideration and sensory functioning than those that didn’t.
However the examine additionally discovered that bodily lively submariners reported worse common well being and sleep as soon as the patrol ended, suggesting that the advantages of staying lively in the course of the patrol got here with some trade-off throughout restoration.

The examine’s authors famous that submarine confinement was an excessive model of isolation. Warship sailors face comparable situations. Lots of the core stressors overlap throughout each environments. These embody tight confinement, disrupted watch rhythms, a complete absence of pure gentle, and fixed background noise.
Such pressures, for naval sailors on lively deployment in a warzone, hardly ever arrive separately. A sailor sleeping poorly may additionally be protecting lengthy watches, is separated from household, unsure when the deployment will finish, and, if provide strains are disrupted, contending with less-than-ideal dwelling situations.
The bodily toll
A January 2025 report (‘Neurotrauma in Naval Operations: Addressing the Unseen Battlefront’) by the Heart for Maritime Technique, a Washington-based non-profit, recognized traumatic mind damage, blast publicity and the physiological pressure of utmost confinement, isolation and stress modifications as under-addressed dangers in naval and submarine operations.
The report argued that untreated neurotrauma can have an effect on a service member’s management capability, decision-making, retention and long-term well being.
The analysis just isn’t one on Lincoln’s crew particularly, however the science does set up that bodily and psychological stressors aren’t unusual amongst sailors. Put collectively, the problems compound into a spot navies all over the world ought to begin paying attention to, the Heart for Maritime Technique’s report suggests.
