Amid 7th Fleet Turmoil, Sailors Open Up About The Navy’s Silent Threat: Sleep Deprivation

By ADAM WEINSTEIN on August 23, 2017

“I don’t think I can remember not being completely exhausted on watch, be it the middle of the day or the seven-to-forever,” says August Sorvillo, a former Navy quartermaster who helped his ships navigate all manners of challenging channels and anchorages. “It’s safe to say I’ve bought enough Red Bull, Monster, and Rip-Its that I could [have made] a sizable down payment on a house.”

Lori Schulze Buresh, a former surface warfare officer, still cringes thinking about the deployment where she stood the Navy’s notorious “five and dime” watches: five hours on, 10 off, then repeat — no matter what time of day or night. “The hardest part is being awake at some point every night and still doing a job all day,” she says. “It is hard on a body and hard on the mind.”

Gotta love the navy when you work 14 hours then sleep for 4 hours, and wake back up to work another 12 hours. ?⚓

After four different groundings and collisions in less than a year in its Japan-based 7th Fleet — including the crashes of the advanced guided-missile destroyers USS Fitzgerald and USS McCain this summer, leaving 17 sailors dead or missing — the Navy is cleaning house and doing some soul-searching. But beyond the particulars of each incident, service officials are intent on identifying broader issues that may leave crews more prone to deadly accidents.

Many current and former sailors have a suggestion for the Navy: Let your crews sleep more.

It’s not a new refrain: Sleep deprivation, long a fixture in all the military services, is accepted by most sailors as a way of life, made slightly more bearable by strong coffee, midrats, and SWOnuts. In the naval service, “Sleep when you’re dead” is the unwritten 11th general order.

‘Watch rotations… aren’t conducive to sleep’

But science shows that this hard-charging ethos can yield a fleet of well-trained watchstanding zombies. In a 2012 military study, 39% of sailors reported that they were “frequently not getting enough restful sleep to function well at work and in their personal lives.” Previous studies have suggested that surface sailors lose out on five to nine hours of sleep every week they’re underway.

In 2015, the RAND Corporation published a two-year survey on sleep in the military, and the findings were dire. It showed “a high prevalence of insufficient sleep duration, poor sleep quality, daytime sleepiness, fatigue, and nightmares” across the military — particularly in the fleet.

RELATED: The Fitzgerald’s Watch Team Could Have Been Mine »

RAND found that out of all military communities, the Navy alone had one significant red flag: Sailors “with prior deployments had greater sleep-related daytime impairment than those without a prior deployment.” This is especially problematic for surface ships, which lean heavily on mid-level officers and petty officers with prior underway experience to conduct bridge and combat information center watches that are critical to safe navigation.

“We have environments in the Navy and the Marine Corps that aren’t conducive to sleep, watch rotations that aren’t conducive to sleep, and people don’t always pay a whole lot of attention to that,” one sailor told the RAND researchers.


‘I have seen and heard things that weren’t there’

The problem is significant enough that when one sailor responded to the McCain collision by sharing her daily work schedule and sleep problems on Reddit this week, the thread exploded with hundreds of commiserating comments from vets of the surface, sub, and naval air communities.

“I averaged 3 hours of sleep a night” on a destroyer and cruiser, the sailor wrote:

I have personally gone without sleep for so long that I have seen and heard things that weren’t there. I’ve witnessed accidents that could have been avoided because the person was so tired they had no right to be operating heavy machinery, including an incident in which someone got descalped and someone else almost losing a finger.

The responses, from veterans and civilians, were wrenching. “I work for an airline,” one commenter said. “If we operated on this schedule they would [shut] us down so fast we couldn’t even look.”

Setting the ‘circadian watchbill’

The Navy knows sleep deprivation is a perpetual problem in its ranks. “Fatigue has measurable negative effects on readiness, effectiveness and safety,” Vice Adm. Thomas Rowden, commander of Naval Surface Force—Pacific, said in a fleet-wide message in 2016. “After a day without sleep, human performance drops to dangerously ineffective levels.”

Rowden and other senior Navy leaders have been taking pointers on keeping a ship’s crew well-rested from a “Crew Endurance Team” of military and civilian experts at the Naval Postgraduate School. Their suggestions include setting a “circadian watchbill” — organizing watches to conform to a 24-hour rotation, more in line with the human body’s natural sleep rhythms.

Asked whether any of 7th Fleet’s mishaps could be directly attributable to sleep and fatigue issues, the sailors are more circumspect. For one thing, there are no easy fixes; for another, everyone’s really busy and tired most of the time.

“It’s a factor, but it’s always been a factor,” one former surface officer told Task & Purpose. “But you’ve got to have watches.”


‘The practice briefing for the pre-briefing’

The officer says that sleep deprivation may be less of a cause than a symptom of bloat in sailors’ responsibilities, including arcane online training requirements (also a target of Secretary of Defense James Mattis), collateral duties, and a host of chores you don’t have to do, but should, like “the practice briefing for the pre-briefing, because the XO didn’t think we were ready [to brief the CO] yet.”

“The focus on collateral duties in our modern Navy [owns] part of the blame for a lot of missed days of sleep,” Sorvillo, the enlisted navigator, says. “On my last ship I, as well as quite a few others, had at least two full time duties to perform before going on watch… Eighteen to twenty hour days was the norm for six to eight months.”

Regardless of whether sleepy sailors can keep it together for a successful bridge watch, the Navy’s grueling schedules may wreck their crews even after getting out of uniform: Research suggests that fatigue problems, once programmed into a service member’s biology, can follow them for life. “[O]nce initiated, sleep disturbances may follow a persistent course, lasting for years after deployment,” RAND’s study concluded. The authors added that “sleep problems are prevalent, debilitating, and persistent in servicemember populations in the post-deployment period.”

That’s no news to Sorvillo. “I’ve been diagnosed with chronic insomnia,” he told Task & Purpose.

Despite leaving the fleet in 2009, he says, “I still get at most four hours of sleep a night.”

I guess you missed the first hand reports... They did not have 12 hours or even 8. A 4 hour sleep you can survive with indefinitely, but I can testify that alertness suffers greatly. Instead of getting 8 or 12 good hours out of the person, you get 16 sleepy hours.

Sleep deprivation is not new to the Navy. All these accidents, though, are. It is a brutal schedule for sure- but I imagine it's realistic prep. for war time.

The other problem is the "stretching" of the Fleet to cover a lot more with a lot less... That puts even more wear and tear on ships and crews.

Although I was not a part of the "sea going Navy"..I was around the ships some..enough to know that even back in the early seventies the ships had proximity alarm systems based on radar...The modern Navy should have active radar plus gps alarm systems to warn of any obstructions...So...Sounds like a possible "hack" to me...windsail...

I can't imagine keeping a ship going 24/7.

We ran pretty hard during field exercises, but that was 2-4 weeks every coupla months.

I've seen guard rails get up and run across the road, like a centipede...and other oddities that come with sleep deprivation.

Maybe that's why working 4-5 18 hour days don't bother me too bad now, when we work disaster response.

I sure don't snap back like when I was in my 20s tho

Waiting to see if TerryK weighs in on this one, since he is experienced with bridge operations. My only sea time was on a carrier, with plenty of people. 12 on 12 off, unless something had to be finished that the relief shift couldn't do, or you don't have a relief shift. Then you stay until you're finished. But anytime we worked any considerable amount past 12 hours, we added on to the off time.

Factor in 45 mins each way commutes, 10-20 minutes to change out for the oncoming shift, meals and shower into that 8 hrs and there isn't much difference...

1962 near the DMZ, 7th Cav, like most had miles of concentina wire to patrol...summer schedule was 4 hr on, 4 off and work the next day. Winter was 2 on and 2 off which meant hardly any sleep at all. These shifts can every 4th day. And for the first 8 months we were issued no ammo...just rifle and bayonet. Due to a rise in the number of cut throats (slicky boys coming through the wire to steal whatever they could); we were finally issue one 8 round clip. It was more than enough to keep sergeants from sneaking up on the guard just for fun. They readily identified themselves when the MI bolt slammed shut.
The tempo of work, long summer marches and guard duty (2 on and 2 off meant no sleep at all for the most part) meant chronic fatigue and this was peace time...more or less. The saving grace was that most were young men with good recoverability.

Try seven hours of commute, about 4 hours of actual sleep. Had a handful of places to pull off the road for a 10 minute nap, very refreshing. You start making bad decisions, a little like a couple of drinks.

Some good points have been made by the OP and probably need to be addressed but that is kind of part and parcel for military service. And as has been mentioned it's also common in civvy life as well if your a firefighter, EMT or police officer and certainly the doctors during their residency working the ER are working 100 hour weeks which scare me more than being sleep deprived on the bridge and oh, airline pilots as well. In the military it's mostly young men and women who can cope a little bit better with lack of sleep. It's more of a problem for the older officers and nco's that are getting up into their 40's or older. We don't usually do as well long term with that kind of sleep schedule.

I can attest to the long-term effects of poor sleep. I spent the first three years of my military service working 6 days a week (2 mid shifts, 2 day shifts, 2 swing shifts, 23 hours off) with occasional longer breaks. I can honestly say that there were days I thought I was losing my mind. I once was so tired after a mid shift that, while driving home in the early morning, I stopped at a green light and sat there for at least 30 seconds before I realized what I'd done. Thankfully there was no traffic, this being an early Sunday morning in Germany.

I ran track in high school and was very healthy, but after those three years I'd gained 30 pounds and my health was terrible. I've never fully recovered from that, and still work a two-shift rotation today so I doubt I ever will.

The issue lately is letting freighters sneak up and hull our destroyers on a semi-weekly basis. Somebody along the command chain needs to pull their head out of where the sun don't shine and make bottom to top changes back to basic, responsible seamanship.:shk:

Working rotating shifts is brutal on the body. Certainly not nearly as brutal as actual combat conditions, but incredibly detrimental to health nonetheless. While I don't believe that sleep deprivation will be found to be the primary cause of these recent incidents, I know it has been a problem in the military for decades. I think this problem could be solved if we learn to work smarter, not harder. We put men on the moon, and yet we can't figure out a duty schedule for 24/7 military operations that doesn't involve long-term negative health effects for troops? With some good ole American innovation we could learn to operate much more effectively at all hours of the day and night.

It's more of a problem for the older officers and nco's that are getting up into their 40's or older. We don't usually do as well long term with that kind of sleep schedule.

Doctors (in Europe and increasingly in the United States) are now no longer allowed BY LAW to work 100 hours weeks, they way they used to; the reason for the law changes is too many horrific mistakes that came down to "Doctor is now sleeping on their feet, they may think they are awake and they may look awake but their brain has simply shut down."

Obviously, military soldiers need to be TRAINED to go without sleep during combat conditions or other unusual circumstances but running people as a regular thing on 4 hours sleep for many weeks and/or 48 to 96 hours shifts is simply GOING to result is even the most dedicated, disciplined and well-intended soldier (aka human being) sometimes having hallucinations, physical collapses and the "sleep walking" effect that finally forced medicine to start reforms (after a lot of really large insurance payouts on both sides of the water).

There is being "lazy" and there is "human biology" and it sounds like the Navy for a number of reasons is pushing the limits (and beyond) of human biology here; again no problems doing things like training people to function in emergencies for extended periods of limited or no sleep (doctors sometimes have to do this too in crises situation) but as a full time thing; this is just wasting people and asking for disasters to happen.

I very much doubt this has that much to do with TWO aircraft carriers being dead in the Water and rammed near the same areas so close together in time (and in the same way) but that doesn't mean it isn't a serious problem that needs to be looked at, and to be eliminated as much as possible.

The four hours at a time for long stretches is really worrying because after awhile people do get "used" to it, but the body/brain WILL take over and start making involuntary steps to enforce rest; the Germans learned that in the Second World War if I recall, when it was found that eventually, soldiers would even fall asleep while marching!

That was the excuse used in medicine to enforce the 100 hour plus weeks and 72 hour "shifts" for interns and younger doctors; until it was finally recognized that the results were so horrific when taken over time (and unnecessary) because while yes, sometimes a doctor may HAVE To do that kind of shift; as a regular thing just because "I did it when I was an intern so you will do it to or your a wimp" wasn't enough of a reason to allow the danger to patients (and to the doctors/nurses/medical staff) themselves.

Human biology is NOT a SNOWFLAKE; it is what it is, and it doesn't allow the majority of people to fully function at any sort of peak level on four hours sleep for months on end and/or repeated 48 to 96 hours "sifts" followed by four hours of sleep.

Now it may be that the article is exaggerating (I've never been in the military or at sea) but science is realizing more and more that it is perfectly possible for a person to "look" like they are functioning when in fact their body/brain has mostly shut down, which it WILL do; at a certain point of sleep deprivation and it is not a voluntary response on the part of the person it happens too.

That is equally true for police, fire fighters, EMT's etc; but in civilian life for the most part; if people are only getting 4 hours sleep a night because of a job requirement for months on end, the physical toll on the employees is likely to result in enough worker's compensation claims that the County/City/State insurance company is likely to complain if the employees don't start doing it first and/or a horrible accident/mistake doesn't bring the situation to light.

The War On Reality
Posted on August 24, 2017
122

Reality is that which, when you stop believing in it, doesn’t go away.
–Philip K. Dick

That is a popular aphorism on the Dissident Right, because it stands in stark contrast to the dominant ideology of our age. The people who rule over us are committed to the belief that says reality will yield to wishful thinking. In fact, they deny reality exists as an objective, measurable thing. That’s where the idea of social construct arises. Our betters are sure that what we foolishly perceive as reality is just an illusion, an artifact of cultural conditioning. If they can convince enough people of this, then observable reality changes.

This is the true divide in the West and why BoomerCons, BuckleyCons, Libertarians and Civic Nationalists are in the same ideological set as Progressives. They accept these assumptions about reality, just with some reservations. The Dissident Right, in contrast, rejects this entirely. Reality, particularly biological reality, is transcendent and independent of human observation. The world as we observe it is quantifiable and measurable. More important, it is largely immune to any tinkering we can do in the short run.

This is most true when it comes to human biology. John Derbyshire did a whole presentation on this at AmRen from the perspective of race. Race realism is just a subset of biological realism. The natural differences between the sexes, IQ differences and personality differences are other aspects. It is why “improving your mindset” sounds laughably ridiculous to someone like me. Your “mindset” is a product of your biology, your genetic makeup. You can no more change it than make yourself taller.

The fact that reality is undefeated, besting all comers, does not stop the cult that rules over of us from continuing to make war on biology.This story is the latest example of how they will destroy the military trying to prove that sex is a social construct.

A number of U.S. Army drill sergeants at Fort Benning, Georgia, have been temporarily suspended from their duties following allegations of sexual misconduct with trainees, the Army base said on Wednesday.

Investigators looking into an initial sexual assault allegation by a female trainee against a drill sergeant at the fort uncovered other incidents of alleged sexual misconduct, prompting a wider investigation, the base said in a statement.
A spokesman declined to say how many drill sergeants had been suspended as part of the investigation, but the statement indicated it was more than one.

Cracking down on sexual assault has been a priority for several years in the U.S. military, which reported in May that anonymous surveys in 2016 found that 14,900 service members experience some kind of kind of sexual assault in 2016, from groping to rape. That was down from 20,300 in 2014, according to the surveys, which are conducted every two years.

People who accept biological reality know it is a lethally stupid idea to have male drill instructors working with female trainees. Men like women, especially young women and they are wired to use every trick in the book to gain access to females. Setting up a situation where males have power over young females in this way, invites the sort of thing the military says they are trying to stop. Having girls in the army is debatable, but if you are, they need to be protected from the males.

Of course, females are wired to seek the attention of high status males. In boot camp, there is no one with higher status to the recruits than the drill instructor. That’s the whole point of the arrangement. The idea is to break down the recruits and build them back up into soldiers. Putting a male in charge of females is going to have the females competing with one another for the attention of their instructor. This is ground floor biology. Even the most disciplined males will be tempted at some point to say yes to the offer.

Again, this is not a new thing. The people putting males in charge of female recruits are the same people putting girls on Navy ships and then acting surprised when the girls get knocked up at sea. Currently, 16% of deployed females aboard ship are pregnant. You cannot serve on a Navy vessel while pregnant so it means these females are reassigned to shore duty. Overall, females in the Navy are 50% more likely to be reassigned to land duty than males, so it is not just pregnancy. It is biological reality.

This means that just about every ship in the fleet has a readiness problem, due to the lack of trained personnel. The Navy has a rule requiring every ship to be at least 25% female, so that means vessels cannot be deployed, because of the shortage of female sailors who are not pregnant. This 25% rule was just implemented. That’s why the pregnancy rates have gone up. It also means the rising pregnancy problem did not result in a reevaluation of the policy. Instead it was met with a new effort to prove that biology is not real.

The thing with the new religion is that it is always at odds with its stated goals. The simple solution to the pregnancy problem is to require all females to be on Norplant. This solves the pregnancy problem. Not only is this never suggested, doing so would set off howls from the cult about sexism. The reason is that such a requirement would require accepting biological reality. Instead of solving the problem or at least mitigating it, the cult prefers to wage a losing battle against biology, destroying the military in the process.

There is a reason reality is undefeated.

It is my belief that many mental breakdowns, especially in the military, are caused by sleep deprivation.

the Germans learned that in the Second World War if I recall, when it was found that eventually, soldiers would even fall asleep while marching!

I found that true, in 50 mile forced marches in Korea 62, we slept by the road in ditches or on the banks of rice paddies because the day time was too hot. We marched at night. A full field pack, rifle etc, little sleep and the fast pace of the march, I found myself falling asleep as one foot left the ground and awoke as it came down to the ground. Towards the end of the march, the line of marchers were really strung out...falling behind, at the tale end was a medic jeep. I found it had caught up with me, but had so many solders draped over every possible surface...no room for me.

The 7th Cav (Custer's old outfit) later became famous in Vietnam as 'Air Calvary.' But in early 60's in Korea, we walked every where we went...or double timed. Boy did we miss those horses!

Thanks USDA, I mean you were deployed in a theater of war so obvious sometimes soldiers or sailors are going to have to be pushed to and/or over the edge (and probably everyone in the military needs to train for this, just as doctors still train for it) but forcing it 24/7; 365 days a year when NOT in direct war/combat is a waste of human beings and just WILL lead to errors and collapses.

The War on Reality also makes some good points, if the ships are not fully manned for whatever reason (including the pregnancy of crew members) then that is obviously part of the problem.

I am a big fan of sleep. Why couldn't it just be as simple as not rotating the watches? Bob has days; Carl has nights?

From the description in the article (and I may not be reading it correctly); it looked like watch was in addition to whatever other eight to ten hour job a sailor has on top of it; now that would work if "watch" was only a night or two a week (most healthy young people CAN stay up 24 hours on occasion, provided they get at least 8 hours sleep afterwards).

What no one can do (it isn't humanly possible biologically) is to repeated work a full day, sleep four hours and then stay up all night (8 hours) work 8 more hours (eat, shower, sleep four hours) rinse repeat for ages and still be fully alert and able to function properly.

The human "machine" breaks down when that goes on for more than a few days, do it for weeks on end and people start seeing things that are not there, jumping at noises that didn't really happen, appear to be awake when their brains have shut down and eventually will fall asleep and/or collapse into unconsciousness.

However, I'm pretty sure the Navy would RATHER blame these accidents on sleep deprivation because they can make it look like they are "working" on the problem just by adjusting work/sleep times and perhaps instituting a "rule" that except when at certain alert levels or during short periods for training; sailors are mandated to get at least 6 to 8 hours sleep in any 24 hour period, to ensure peak performance and to avoid accidents.

I just made that up, the military could consult with their own doctors and other professionals to determine what is possible and practical; feed that to the public while the scramble to solve the more likely actual causes of the accident like hacked parts made in China etc.
