Aircraft Carriers III

Jeff Head said:

Those are very high speed anti-torpedo, torpedoes. On the carriers they are positioned in four places, ech place has two cradels to fire torpedoes and hold six torpedoes each. So there are twenty four anti-torpedoes, six on the four corners.

This gives them twelve towards the after portion of the ship.

It's something we have needed for a long time...and they are finally deploying them...and I for one am very glad to see it.

Executive Summary
• During FY17, USS Dwight D. Eisenhower and USS George H. W. Bush completed deployments and USS Nimitz started a deployment with the Torpedo Warning System (TWS) and Countermeasure Anti-Torpedo (CAT) system. Like previous carrier deployments, the Towed Active Acoustic Source (TAAS) engineering developmental model was not reliable and the Dwight D. Eisenhower, George H. W. Bush, and Nimitz deployed with a passive-only TWS array. Prime contractor personnel deployed aboard the carriers to operate and maintain the TWS system, train Navy operators, and collect system data.
• In 4QFY16, the Navy reduced the FY18 and beyond funding for TWS and CAT, resulting in the suspension of contractor development and government developmental test and evaluation after FY17. The Navy funded the program to sustain the existing permanent TWS and CAT installations.
• In October 2017, the Navy’s Operational Test and Evaluation Force (OPTEVFOR) conducted a third Quick Reaction Assessment (QRA) in conjunction with contractor testing. The combined QRA and contractor tests demonstrated the ability of TWS, under optimal conditions and when manned by qualified sailors and contractors, to successfully alert on an inbound threat torpedo and the CAT system’s ability to successfully engage a torpedo. The testing also demonstrated that the Navy has made significant improvements to the reliability of the TAAS."

picture (I hope, the deeplink is functioning with everybodys browser) You can see the eight spots of the eight reactors, over RC 2B is a tent with a small gantry crane (some day I saw a picture of a gantry crane that fits into the hangar of a carrier for work on the reactors, but I never found this picture again; I will deliver it, if I pick it up a second time).



I think the trip to Bremerton is only postponed to indefinite, because Enterprise will never again set sail on its own power.

Intrestering...What shall the USN do when it comes time to scrap the Nimitz class? Yikes. They better have the issues worked out.

Three Aircraft Carriers to Change Homeports

From Commander, Naval Air Forces Public Affairs

SAN DIEGO (NNS) -- The U.S. Navy announced Aug. 2 that three Nimitz-class aircraft carriers, USS Carl Vinson (CVN 70), USS Abraham Lincoln (CVN 72) and USS John C. Stennis (CVN 74) will conduct homeport shifts.

USS Abraham Lincoln, currently located in Norfolk, Virginia, will rejoin the Pacific Fleet, making San Diego its homeport. Abraham Lincoln, commissioned in 1989, previously served in the Pacific Fleet from 1990-2011 before moving to Norfolk for midlife refueling.

The other two carrier homeport shifts are tied to carrier maintenance. John C. Stennis, currently homeported in Bremerton, Washington, will change homeports to Norfolk in advance of its midlife refueling, or reactor complex overhaul (RCOH) at Newport News Shipbuilding. John C. Stennis was commissioned in 1995; Nimitz-class carriers are built to last 50 years.

USS Carl Vinson (CVN 70) will conduct a homeport change to Bremerton in advance of its docking-planned incremental availability (DPIA) at Puget Sound Naval Shipyard.

"Unnamed sources",, told me several years ago that Abraham Lincoln would return to the Pacific Fleet...eventually...Honestly I expected CVN-72 to be back on the west coast buy now...Change is coming.

Years ago the USN was pondering homeporting a CVN in Pearl Harbor. I remember posting an article about that but I can't find that article now...

thought I might share what I just noticed:

Well, well well.. I did finally find the article. the link in the article is dead. Posted by yours truly nearly 12 years ago.

Currently the USS Carl Vinson(CVN-70) is undergoing a major re-fit and refueling in Newport News VA. The USN wants to return the ship to the west coast in 2009..But It will more than like be homeported in Hawaii or Guam.

Navy considering moving USS Carl Vinson to one of four ports

By Audrey McAvoy
ASSOCIATED PRESS

10:26 p.m. August 21, 2006

HONOLULU – Four Navy bases in California, Hawaii, Guam, and Washington state are in the running to become the new homeport of the USS Carl Vinson, a nuclear-powered aircraft carrier that is currently undergoing a three-year-long refueling overhaul, the head of the Navy said Monday.
Navy Secretary Donald C. Winter told reporters he would decide by April or May whether to base the Vinson at San Diego, Pearl Harbor, Guam or Bremerton, Wash.

The ship would be ready to move to its new home once its nuclear fuel is replenished in 2009, Winter said at a media round-table in Honolulu.
Winter said he would consider each base's strategic location, the cost of infrastructure upgrades required to accommodate a carrier, and proximity to an airfield when making his decision. Training opportunities for the carrier's 5,000 sailors would also be a key factor, he said.

“We have to weigh all of these issues very carefully and consider what makes the best sense for the United States,” Winter said. “There's a lot of trade-offs there. We'll just have to see how it all comes down.”

The Navy currently has five aircraft carriers in the Pacific: two in Bremerton, two in San Diego and one at a U.S. Navy base in Yokosuka, Japan.

Navy leaders have said they were considering moving an aircraft carrier to either Hawaii or Guam to help them more rapidly respond to potential threats in the Asia-Pacific region.

But the Pentagon's Quadrennial Defense Review report, issued in February, didn't mention the possibility as some observers had expected. It only referred to a plan to keep six carriers in the Pacific.

Guam, a U.S. territory a few hours by plane from East Asia, would require more substantial infrastructure upgrades than any of the other three candidates.

Moreover, Winter said the military's plans to move 8,000 Marines to Guam from the southern Japanese island of Okinawa added to the complications of moving an aircraft carrier to Guam.

On the other hand, Guam is closer to areas military leaders would most likely want to have the USS Carl Vinson patrol.

Hawaii, meanwhile, is closer to Asia than the West Coast and has a more highly developed network of roads, schools and other infrastructure than Guam.

But Hawaii suffers from high housing costs and limited land area. Military personnel also frequently complain about the poor quality of island schools.

Guam's business community has actively campaigned to host an aircraft carrier.

Democratic Sen. Daniel K. Inouye, a ranking member on the Defense Appropriations Committee, has lobbied for his home state of Hawaii to be selected.

Separately, Winter confirmed the Navy would base the USS Hawaii, its newest nuclear-powered submarine, at Pearl Harbor. The ship, which was christened in June, will likely be ready to move to its namesake state in 2009, Winter said.
