Usns John Glenn

Sun Feb 02, 2014 4:23 pm

Sen John Glenn has a ship named after him.

Ship is a mobile landing platform or mobile pier for offloading purposes. It can flood down, partially submerge, to offload LCACs & barges.

Maybe some of the Navy folks on the board can explain how the ship offloads an LCAC or barge? Artists impressions of the ship seem to indicate the presence of a well deck beneath the main deck, however photos of the actual ship don't seem to show that. Does the ship list to offload an LCAC while still keeping a portion of the main deck dry?

The MLP has the ability to carry modules to customize what the ship can do. The first module delivered allows the MLP to simultaneously load three LCAC's.

Basically, a Military Sealift Command RO-RO ship will pull up and lash up with the MLP and drop a ramp from the side down to a raised vehicle deck on the MLP. The vehicles are then driven from the RO-RO, onto the MLP, and then onto an LCAC to be dropped off on the shore. The MLP has the ability to partially submerge the well deck to allow LCAC's or landing craft to come onboard.

Future modules will allow the MLP to enhance its role in seabasing, such as a helicopter deck to allow helicopters and F-35B's to use as a lily-pad. It will free up the Navy's amphibious assault ships to perform other duties after a landing, and allow the Marines to sustain operations ashore where there is no access to a harbour. The best way to think of what the MLP will enable is to think of the MLP's as the Mulberry harbours that were built for the Normandy landings during World War II, but more mobile and more flexible.

You can read up on the MLP and why the Navy and Marines are excited about this ship here:

It appears the ship can ballast down as needed either to completely submerge the deck or just to the water' s edge. I don't think there is a well deck on the mobile landing platform. In the pictures from the NASSCO site the LCAC module is not installed. You're just looking at the "blank canvas" before they've installed any mission modules.

When operating with LCACs, amphibious ships ballast down "to the sill" the well remains dry for the entire evolution. The water level and the level of the well are level and the LCAC just drives right in. It comes off cushion and loading commences.

With conventional landing craft, the ship has to ballast down enough for the craft to float in and then ballast up to create a dry well to load and unload the landing craft. The ballasting operation takes time that the hovercraft eliminates.

I have always been fascinated by the MLP design. Its probably one of the smartest new abilities added to the USN in a long time. Like the Admiral in the first link ThePointblank posted said, "It’s 800 feet of ‘use your imagination." Floating pier, LCAC carrier, container ship, ferry, refueling station for helicopters, floating go cart track... get creative.

I'd consider having a ship like that named after Glen as a bit of an insult to the man, especially when that congresswomen who gained notoriety for being shot (Giffords) got a LCS named after her, when at best a harbour tug would have been more than suitable.

I would disagree about naming the ship after John Glenn. For one, the John Glenn served in the USMC, and this ship will operate in support of the USMC. The lead ship, USNS Montford Point was named after Montford Point, which was the site for recruit training for the first African Americans to serve in the Marine Corps. The third ship is being named after Lewis B. Puller, who was one of the most decorated Marines in US history, and is a well-known figure in U.S. Marine Corps folklore.

Then name something like an LHA after him, but a cargo ship, nah that's weak.

Considering that a number of Military Sealift Command ships are named after prominent or decorated servicemen (e.g. Leroy A. Mendonca, Herbert K. Pililaau, Roy Benavidez, William M. Callaghan), its an appropriate name.

Also, USN naming conventions dictate that amphibs are to be named after early American sailing ships, U.S. Marine Corps battles, or legacy names of earlier carriers from World War II, not after people.

Naming LCS-10 after Gabrielle Giffords is somewhat consistent with USN naming practices. For one, the more traditional name that would have been acceptable to USN practices would be to name the ship after Tucson, in honor of the city and all those killed or injured during the shooting, but that name was unavailable as there is a USS Tucson in existence (it's a Los Angeles-class submarine). Furthermore, the practice of naming ships after former members of Congress is already well established. Furthermore, the Navy Secretary was also seeking to pay tribute to all 535 members of Congress - a very select group of 535 elected politicians who serve the US everday. The fact that Giffords is a Navy spouse simply reinforced the Secretary’s desire.

Was it bending the naming practices a bit? Yes. But it is consistent with past practices, as there has been some exceptions to the conventional naming practices in the past. In fact, of the 280+ ships in the USN, 11 have names that deviate from an established type naming convention. Six of these exceptions are consistent with a now well‐established special cross‐ship type naming convention for “well known national and Congressional leaders,” and three more are consistent with a type or class’s original naming convention that subsequently changed.

The only two remaining exceptions - representing less than one percent of all active ship names in the entire Navy - are USS Winston S. Churchill and USS Gabrielle Giffords. Both are consistent with the long established tradition of making periodic exceptions to convention.

General Dynamics has displayed a model of the MLP in the Afloat Forward Staging Base configuration:

http://www.navyrecognition.com/index...tion=com_content&task=view&id=1731



This configuration includes an accommodation block for 250 personnel for the flight crew or other mission personnel such as Navy Seals or Marines. This space also features a hangar capable of fitting two MH-53 helicopters plus aviation maintenance and mission specific spaces. In this configuration, the MLP can perform mine countermeasures with the MH-53 helicopters, and conduct many of the missions a larger and more expensive amphibious assault ship can perform but at a much lower cost.

I was curious about the MLP concept so I did some googling and came across this artist concept of it ballasted down to off load LCACs.

I agree. There was no need to name a boat after her.

Anybody remember a couple years back when a few people here were griping about naming a aircraft carrier after George H. Bush. Funny part was those complaining the GHB who flew avengers off carriers in WWII complained that jimmy carter didn't have one named after him. Apparently they didn't realize that he had a sub named after him (he was a submariner in the navy)

The man got a much better Congressional perk: he got to ride the Space Shuttle!

Imagine if it was that mission that blew up....

Wake now, discover that you are the song that the morning brings
The heart has its seasons, its evenings and songs of its own
