As a rule of thumb, warships do not have portholes, this is for multiple reasons, including light pollution that can give the ships position away, as well as causing weaknesses in the ships hull where the Portholes are. The only portholes on most ships are either at the wardroom or the captains quarters. To be honest, it never really bothered me when serving, if I wanted daylight I could always goto the upperdeck for some air, or goto the bridge to chill out and chat with the QM or OotW, most of the time I was too busy actually working to care!Originally Posted by 9166

Seeing all the photos of the model reminded me that I saw this and took the pics at Farnborough 2010.
There is an interesting hint in this image http://farm6.staticflickr.com/5159/7...9324f972_k.jpg as to how they will skid SB03 into place. Look at the blocks in the bottom of the dock. Looks like roller bearings. Also there is a hint about how they are able to drop the rings in place so accurately. The layout of the incoming bulkheads are laid out on the open deck of LB02. This is more and more like a giant Lego set every day!!

Nice photos... and good spot on the possible way of skidding..... BTW... do you have any images of the other ship models you can see in the background?
looking at that image http://farm6.staticflickr.com/5159/7...9324f972_k.jpg the blue is not paint but some sort of water proof covering spayed on as it has been cut away where CB02E is located.
amazing way to do things
Royal Netherlands Navy and Thales Sign Contract (Source: Thales; issued June 27, 2012)
Today, the Netherlands Defence Materiel Organization and Thales Nederland signed an agreement to modify the four SMART-L volume search radars installed on the “De Zeven Provinciën” class air defence and command frigates of the Royal Netherlands Navy. The new SMART-L radar will be optimized for the early detection of ballistic missiles.
SMART-L will be able to detect ballistic missiles shortly after their launch. It has this early warning capability simultaneously with its traditional air defence capability. SMART-L will be able to detect and track several threats simultaneously and make an accurate calculation of each missile’s ballistic trajectory, and accurately estimate its point of impact as well as its launch position. SMART-L is a volume search radar that scans large volumes of the air space so that it can detect missiles without external cues.
The SMART-L and its sister, the S1850M Long Range Radar are used by the navies from Denmark, France, Germany, Great Britain, Italy and South Korea. All these radars could in principle profit from the modification package contracted by the Netherlands' Defence Materiel Organisation.
Gerben Edelijn, CEO of Thales Nederland: “This contract confirms our leading position world-wide in naval sensor technology and system integration. Through this contract we support NATO’s long-term plans for a maritime defence against ballistic missiles.”
I was wanting if Mod were thinking of doing the same to our S1850M radars, especially since the Chinese are look as ballistic anti-carrier missiles
I don't. I seem to remember that the display, which was a general BAE systems show, had various models of future warships, including Type 45 and Type 26. It is probably one of those. I was a bit starry eyed at the CVF, and therefore didn't pay too much attention to the other stuff there, if I am honest!
EDIT - Having reviewed the pics, there seems to be something similar to a Type 26 in the background, and some sort of smaller, GP vessel - possibly an early concept of Black Swan?? - in the background. I have no idea about the other stuff.
If you look at the earlier shots of CB E-ring "flying" in, you can see that the frames and trusses do not come all the way down to the bottom of the bulkheads. The whole thing appears to be designed to slot over the foundations on the deck of LB02, allowing extremely accurate placement of the block. That is all the more remarkable given that they were designed and constructed hundreds of miles apart.
In actual fact light polution is not a significant factor in having portholes on ships,if you have served on a ship with portholes you will know they have 'deadlights',these are solid metal covers that swing down from the inside and screw securely shut to cut out any light from the vessel.At command to 'darken ship' all these are shut and checked. Also as most of the largest vessels in the RN were built in an age of portholes,I very much doubt that hull integrity is a reason,I have never heard of a vessel foundering due to any weakness caused by this.
The main reason modern warships do not have portholes is NBCD,Nuclear,Biological,Chemical and Damage Control. To put it in a nuthshell,the fewer opening on a vessel the less is the chance of any ingress of foreign agents in the ship.
The ship is closed down and sealed from the inside,a pressure is then built up inside the ship greater than the outside pressure,thus in theory preventing anything entereing the 'Citadel'.
I served on one of the first class of vessels to be built 'mostly' to these standards,a Tribal class frigate. In testing the system we closed down the ship to the required damage control state.
We were the overflown by an aircraft which released a harmless chemical agent which enveloped the ship.We stayed closed down for the required number of hours (I forget which now) and were then boarded by a team of MOD scientists who took reading throughout the ship.
Guess what,the 'Citadel' idea didn't work and they found reading of said chemical as far down as the engine room. I hope things have improved in the meantime.
looking at the flying CB E-ring the vents for the engines already mounted on the deck of LB02 before being cover by CB E-ring ( there to the left hand side where 5 workmen are standing)
they look very relaxed coinciding there 500t of metal above there heads

edit: then again looking at http://farm6.staticflickr.com/5159/7...9324f972_k.jpg there looks like it has been fence off where it will be lowed ,so H&S are on the job.
these large pic's are fascinating views of the build.
ACA thanks you.
"Elf an Safety" is somewhat unfairly criticised I think!!! I'll grant you that it's a bit precious when they put those "caution - wet floor" signs out in the office. I always trip over the bleeding things. However, a fence preventing me from falling 70 feet to an early death as a splat on the floor of Gracing Dock no 1 seems sensible!! That's what the H&S act should be about, not stopping brave firemen going into waist deep water...
Interesting, had no idea it was to do with the Citadel, makes sence though. On the Type 23 frigate not all of the engine spaces are considered a secure part of the citadel (atleast when I was on them). Saying that the pressure inside the ship is slightly higher than the pressure outside, so the chances of air getting in though any other means than though filters is pretty minimal.
I knew about the deadlights after having to carry out 'darken ship' on many occasions, although on the Type 23's I served on, the only Portholes are in the captains quarters and on exterior doors leading into the Citadel.
Always nice to chat on these forums, learn new stuff everyday
I was not meaning criticizing "Elf an Safety" , I only noticed that the men were not in danger of getting squashed after I looked at the completed lift picture and the flying picture to see the area was fenced off.
I was pulling your leg mate!
I was under the impression it was to do with keeping a clean superstructure, to reduce radar returns. I don't doubt the utility in a CBRN environment, but they were still reasonably common in cold-war designs (eg T42). Admittedly it's an assumption and I've never actually verified it.
In these days of low energy fluorescence and (certainly in QEC) large onboard spaces, the utility of hull openings of any sort is limited to more than just getting fresh air. On that note, I can't imagine being on a bridge without wings (again with the QEC).
