In my earlier postings, I talked about the routes for ships in the Arctic. Today there are more news on that:
The change will have ramifications beyond summertime, experts said. Having open water each year would mean that almost all ice forming in winter would be freshly frozen and just a yard or so thick.
This would greatly ease the task of maintaining shipping lanes with icebreaking vessels, said Lawson W. Brigham, deputy director of the Arctic Research Commission, a body that advises the White House on Arctic matters.

I won't be surprised if those models are wrong and the pace of meltown is even faster!
The researchers, funded by NASA, said the ice retreat was likely to remain constant until 2024, when the process would suddenly quicken.

In 30 to 50 years, they concluded, summer sea-ice would have vanished from almost the entire Arctic region.

But their forecast may already be out of date, says Chris Rapley, head of the British Antarctic Survey. He said a recent study suggested emissions were rising more than twice as fast as in 2000, and this was likely to speed up ice loss even further.

"The study may be an underestimate of when the Arctic summer ice might be all gone," he said.

USS George Washington (CVN-73) re-fit ahead of schedule

CVN-73 re-fit is ahead of schedule. The Washington is scheduled to relieve Kitty Hawk in Japan sometime in 2008. I believe the spring is the target.

GW's Planned Incremental Availability Plus Docking Ahead of Schedule
Story Number: NNS061213-02
Release Date: 12/13/2006 12:58:00 PM


By Mass Communication Specialist 2nd Class Dave Reynolds, USS George Washington Public Affairs

PORTSMOUTH, Va. (NNS) -- December marks the third month of USS George Washington's (CVN 73) (GW) Planned Incremental Availability plus Docking (PIA+D) at Norfolk Naval Shipyard (NNSY).

PIA+D coordinators are pleased with the progress that contractors, shipyard workers, and ship’s crew are making.

Lt. Cmdr. Bill Pollitz, GW’s maintenance manager and overall availability coordinator, said that since PIA+D began, team GW has completed ahead of schedule nine of the 18 milestones passed so far. The other nine have been completed on time.

Ninety-five additional milestones and key events are scheduled for the availability period.

“This is a testament to the hard work, dedication, and most importantly, teamwork, by team George Washington,” said Rear Adm. Garry R. White, GW’s commanding officer. “And that team includes not just our Sailors, but all of the shipyard workers and contractors who have made this such a successful availability to date.”

He added that he and his team are determined to continue that success through the completion of this yard period.

“We’re getting further ahead every day,” said Pollitz. “When you come in ahead of schedule, you come in on or under budget. That’s a rule.”

Last month, NNSY workers set a precedent by removing the ship’s main mast in one piece, saving both time and money. Pollitz said masts are usually removed in three sections.

The evolution, completed almost three weeks ahead of schedule, paves the way for the installation of Capstone, an electronic suite for combat systems and operations.

“By meeting this milestone three weeks ahead of schedule, we have been able to make the preparations for the new mast installation ahead of schedule as well,” said Lt. Cmdr. Ralph Roe, GW’s combat systems maintenance officer and capstone coordinator.

Communication and planning were the keys to successful removal of the main mast, added Roe.

“Everything from the initial planning and calculations by the engineers to the actual rigging and lifting the 100,000 pound mast using the contracted commercial crane was orchestrated with precision,” said Roe.

The new mast is expected to be installed in January, and then populated with antennae and cabling. The larger, more stable mast will provide GW with improved war-fighting capabilities.

But the main mast replacement is only one of the upgrades in progress aboard GW. The ship’s four propellers have been removed two weeks ahead of schedule, said Pollitz, and will soon be replaced by four state-of-the-art propellers.

Contractors from Earl Industries are blasting sections of the hull down to bare metal, and repainting the areas not painted during GW’s last availability period.

GW’s crew is getting involved as well, with more than 200 Sailors working to improve quality of life by refurbishing 273 staterooms, comprising 746 racks, and 14 berthing areas, comprising 561 racks. Pollitz said the habitability team remains ahead of schedule.

GW is undergoing the $300 million availability in preparation to relieve USS Kitty Hawk (CVN 63) as America’s only forward-deployed aircraft carrier.

“We look forward to an on-time delivery in excellent material condition,” said Pollitz.

A question that just came to my mind.
Why has every CV(N), sea controll carrier etc. have it's super structure on the right (stareboard?) side ??

You mean the island..I duuno. I do know it has something to do with the operatioanl ablity of aircraft. And not all CV's had a starboard side island. Some IJN(Imperial Japanese Navy) CV's in WWII had port(left) side islands as an expermint. I do not know why. Maybe Jeff or Obi Wan knows.

IIRC it is tradition from good old days of propeller driven fighters. Thanks to propeller momentum fighters were going left while landing so island was put on the right side...

Ps. sorry but my English lacks correct terms to describe that properly but I hope you got the idea:(

Thanks for that isthvan, I understand what you want to say. So it started with a necessity and then was kept because it has ever been that way :)

Most pilots are right handed and if they have to abort a landing (wave off / go around) they tend to veer to port (left). During the 1930s the IJN experimented with operating pairs of carriers, one with a starboard island (Kaga and Soryu) and one with a portside island (Akagi, and Hiryu) intending that the ships sail side by side with their islands near to each other to permit clear communications (signal lamps and flags, radio silence of course) while their respective air groups orbitted in opposite handed patterns to prevent interference. The ships with the portside islands suffered a much higher landing accident rate and the experiment was soon abandoned, but there was no time to refit the ships with starboard islands as war was immenent.

The original plans for HMS Eagle and Hermes (c 1919) included two islands (one port one starboard) with a platform connecting them in a 'goalpost' configuration, but model tests lead to the single island finding favour.

Obi Wan glad to see you are posting agin! And thanks for that short history lesson on the island.

Along the same line of discussion..back in '74 when I was onboard the USS Hancock (CVA-19) during indocrination class we were shown pictures of aircraft being "deck launched" off the aft end of the flight deck. I guess this was some sort of experimet by the USN.
-------------------------------------------------------------------

On to a diffirent subject..The USN has 12 carriers in commision. But one of these ships, CV-67, is operating in a reduced status(no flight operations) because it's ablity to operate aircraft is deminished because negelected re-fit by the USN. This is shameful.:mad: The USN has long wanted to de-comission the ship but the US congress has refused. The USN then kept cancelling major re-fits. Now with the approval of the 2007 US DoD budget the JFK will be removed from service. The USN is planning to send the JFK to Boston MA for one last hurrah in March 2007.

The exact date of de-comissioning has not been established. The JFK was offered to NATO & the US Department of Homeland Security but it was refused by both agencies.......

JFK to visit Boston before decommissioning starts

By Mark D. Faram
Staff writer

The aircraft carrier John F. Kennedy returns home to Naval Station
Mayport, Fla., after carrier qualifications in December 2005. Navy
officials have approved a plan that will take the ship to Boston for
a final port visit next year. — MC2 Tommy Gilligan / U.S. Navy

The Navy is still mulling the details of the ailing aircraft carrier
John F. Kennedy's decommissioning, but officials have made the
decision to give the ship one last hurrah before taking her out of
service.

"The Navy is developing a detailed decommissioning plan befitting of
her distinguished history of service to our nation," said Capt.
Conrad Chun, spokesman for Fleet Forces Command in Norfolk, Va.

"The final decommissioning date has not been set. JFK will remain in
Mayport [Fla.] for some period of time. The exact timeline for the
decommissioning process has not been finalized, either."

Chun confirmed the decommissioning will take place before October
2007.

Officials have approved a plan that will take the ship to Boston for
a final port visit. Although Chun could not confirm the information,
sources tell Navy Times that some artifacts from the ship could be
turned over to the John F. Kennedy Presidential Library and Museum
during the visit; a number of items are onboard that traditionally
would be returned to the family.

The trip is "likely to be in March," he said, though that date could
be a little earlier or later and is "contingent on the ship
completing all boiler maintenance successfully. "

That's because the ship is badly in need of maintenance. Though
officials do not expect there to be any problems, they want to ensure
the ship is safe to make the trip. Chun expects that "all eight
boilers will remain operational, " though officially they only need
two of them operational for safe navigation.

It's not just the boilers that could need some work.

Officials said that while the flight deck is not certified to fly
fixed-wing aircraft, it can handle helicopters, which officials see
as necessary for the transit up the East Coast during the winter.

But the ships' certification to fuel aircraft is set to run out Dec.
31, and officials were still unsure if that could be simply extended
or if a re-certification is necessary.

Upon returning from Boston, the ship's inactivation availability will
officially begin, Chun said.

NATO, DHS said no

Since congressional approval came in October, Navy officials have
been mulling multiple proposals to take the ship out of service,
according to a briefing document obtained by Navy Times and confirmed
by Navy officials as authentic.

That document outlined four proposals, all of which had the
decommissioning work starting at Naval Station Mayport; two of the
options had the Navy towing the ship to Norfolk or Philadelphia to
complete the work.

"Specifics regarding where all the work will be accomplished has not
been finalized," Chun said, though he expected that much of the work
will occur in Mayport.

The briefing document said the ship will be taken to Philadelphia
once deactivation and decommissioning is complete, but beyond that,
her future is uncertain.

Chun did say that Congress mandated that the Navy offer the ship to
both the North Atlantic Treaty Organization and the Department of
Homeland Security before deciding on the vessel's final disposition.

"Both NATO and DHS have responded to the offer and declined," Chun
said. "The JFK will be decommissioned and removed from the Naval
Vessel Register by [the secretary of the Navy]."

Once stricken, the ship could be disposed of by the Navy as a target
ship, as happened to the carrier America, or could be scrapped. The
ship could also be donated as a museum or historic memorial.

I'm curious about the JFK being offered to NATO, in what capacity? As a target ship? For transfer to one of the member nations navies? For use as a floating command ship? By all accounts refitting her for further service would be astronomically expensive for a limited return on the investment compared to building a new vessel (eg a CVF). Likewise, just what would the Department of Homeland Security want with a non operational aircraft carrier (or even an operational one for that matter)? I wasn't aware the DHS had a fleet of naval aircraft in need of deployment overseas...
