"Berthing compartments" is the general term on Navy ships, and no, hatches are not typically sealed. Hatches that were sealed while sailors are sleeping in a compartment would present an egress issue should they have to evacuate rapidly.
Affirmative
Video will help to explain hatches. As soon as the ship sets condition ZEBRA the hatches are sealed to maintain a watertight integrity. Any damaged portion of the ship should be sealed from the other compartments. It is not known what condition the ship was at while in transit. Obviously it didn’t sink so they maintained integrity. Whoever was behind a sealed compartment that flooded is most likely one of the ten casualties. Once condition zebra is set you must get permission from Damage Control to pass through any watertight doors.
S.O.P. for hull breech is to seal off areas affected by the breech for loss-prevention. All areas of naval vessels are divided into compartments which can be sealed off in the event of a loss of hull integrity by water-tight doors.
In my day (75-87), "berthing" compartment doors were not normally closed, unless General Quarters (GQ). That's the first thing sounded when hit by anything or an impending threat. IIRC, each door and hatch had a specific letter on it - X being always closed. Y being closed under certain circumstances. Z even less. Depends on the configuration of the particular ship's compartments. I could have the designations wrong, so I pinged the 2 best Navy guys on FR.
That said, once the McCain was hit they would go to automatic GQ which is broadcast over the entire ship which requires every door/hatch to be closed no matter the letter designation. There have been times that sailors had to be sacrificed to keep the ship from sinking and taking all down. Happened many times in WWII. Watch the movie, "Crimson Tide" where the Captain had to sacrifice some guys in the bilge bay to keep the sub from going down.
GPS is based on the longitude and latitude information THAT WE SEND OUT. If that’s messed with - ships could be in a harbor and ‘think’ they’re out to sea... Planes landing would have the same problem... their ‘navigational equipment’ could be telling them one thing and the reality would be another.
Read the link in my last post ...it looks to me like someone’s messing with navigation systems... could be the same with systems used in ICBM’s navigation. If I’m right - we’ve got a problem.
Yes, most hatches are secured.
My experience was on FF’s, FFG’s and various gators.
The devil on my left shoulder looks at that statement and says "I don't know..."
When entering port ship sets sea&anchor detail. Typical to set a higher level of watertight door settings during those evolutions. X-ray was normal steaming, yankee was modified higher level, zebra was for general quarters. We ran yankee at sea and anchor I’ve heard some commands do different. There are always some sealed spaces onboard.
There is obviously some systemic problem in our Navy, whether funding, over-deployment, training, etc. Still, I’m glad to see the Navy holding to tradition of relieving (firing) those who are not fulfilling the mission - from Executive Officer to Captain now to fleet Admiral. Not sure why the Command Master Chief was fired on the Fitzgerald. Probably because he is top enlisted and has similar responsibilities.
Not really ... it is based on time signals sent from satellites in known orbits. The receiver computes its location in 3-space based on receiving signals from 4 or more satellites. These signals can be jammed, rendering the receiver unable to compute its location. With more difficulty, they can be spoofed causing the receiver to compute an incorrect location. As a receiver moves away from the source of jamming/spoofing, it will begin to detect correct signals and correctly compute its location.
Appointed 7th Fleet Commander under the Obama Administration in September 2015:
So at least 17 sailors have been killed and three ships have seriously crashed in 23 months of his command of the 7th!
Agreed, but it has been going on longer than the brass or politicians want to admit.
That's why we have a "Pause" in operations and quick firings all of a sudden THIS time.
The American Public is beginning to catch on from these repeated incidents and needs to be misdirected so as to NOT discern the real cause, Political Correctness being forced on the military.
Minuteman ICBMs use inertial navigation. There is no use of GPS anywhere in the flight profile. There is no use of GPS anywhere in the targeting. I know, I did that for a living for several years.
Cruise missiles do use GPS in some cases but they are not ICBMs. Navy SLBMs use inertial guidance like Minuteman but the subs launching them can use either inertial guidance or GPS to establish their launch position.
All of them if a collision alarm was heeded.
I have so much respect for sailors. One of my worst nightmares is drowning. I would rather do a night HALO jump (over land of course).
That’s great in theory, but when frames and sheet metal are twisted and displaced, I think you can envision a situation beyond the engineering limits of the design.
“GPS is based on the longitude and latitude information THAT WE SEND OUT.”
My Galaxy S7 also uses Russian GPS.
Sometimes doors very near the point of impact will get damaged. Which is part of why ships are designed with small chambers so one broken door means two small chambers flood.
