Large Amphibious Assault Vessels

I must be missing something... how is the Juan Carlos/Canberra design not designed for STOVL?
It's capable of handling the mission, but ship compatibility trials need to take place to make sure that whatever they intend to fly off of her won't cause damage or interfere with operations, and if modifications are identified, they need to happen. Also space needs to be allocated to store tooling, spare parts, places to conduct maintenance, munitions, etc. Lots of work and paperwork to do and sometimes navies will forgo such work.

Cool video of Canberra class Island getting preped to be lifted onto the ship.

Great looking ship, It'd look even better with some F-35s aboard.
That video was shot in March. And that was just half of the Island. I wonder if the whole thing has been lifted on deck by now?

Yeah, but those aren't show stoppers if they want to. The ships are clearly designed with STOVL in mind...

The fact that the Australian Navy left the ski-ramp on there says that they reserved that capability so they could add it later any time they want.

Those vessels were designed specifically for STOVL for Harriers, Ospreys and ultimately for F-35Bs. The Spanish intend to use them that way for sure...and I expect ultimately the Australians will too. The only question really is whether they will buy F-35Bs or not, and if so, how many?

World Maritime News said:
Huntington Ingalls Industries’ Ingalls Shipbuilding division’s multipurpose amphibious assault ship America (LHA 6) returned Saturday from successful builder’s sea trials in the Gulf of Mexico. The America spent five days operating the ship at sea, where it conducted more than 200 test events.

“It’s an awesome feeling riding this ship, knowing the hard work that took place to get her ready for sea trials,” said George Jones, Ingalls’ LHA 6 program manager. “The LHA 6 team continued to work diligently during our time underway. The ship performed well, and our team will work to ensure LHA 6 will be prepared for her acceptance trials. We have confidence this will be a great opportunity for America to prove her mettle as she prepares to enter the U.S. Navy fleet.”

During builder’s trials, America performed all required sea trial evolutions, including the operation of the gas turbine/electric-powered propulsion system. Other tests included anchor handling, flight operations, and combat systems’ evaluations.

“America, designed to take sailors and Marines into harm’s way, proved her seaworthiness during builder’s trials,” said Richard Schenk, Ingalls’ vice president of test and trials. “The test and trials team implemented a rigorous schedule of testing, including a day of dock trials, before the ship left. The Ingalls team and the ship performed very well. We look forward to continuing the hard work on our company’s newest large-deck amphibious ship as our test group works with the LHA 6 program/ops team to prepare for acceptance trials.”

The ship will now prepare for acceptance sea trials in late January to demonstrate the same tests and operational success to the U.S. Navy’s Board of Inspection and Survey (INSURV).

When America enters the fleet, she will be the flagship of an Expeditionary Strike Group, strategically positioning Marine Expeditionary Units ashore across a full spectrum of missions, including humanitarian, disaster relief, maritime security, antipiracy and other operations while providing air support for ground forces.

America-class ships are 844 feet long and 106 feet wide and displace 44,971 long tons. The gas-turbine propulsion system drives the ships in excess of 20 knots. They will accommodate a crew of 1,059 (65 officers) and 1,687 troops. The America-class will be capable of carrying a Marine Expeditionary Unit, including Marine helicopters, MV‐22 Osprey tiltrotor aircraft and F‐35B Joint Strike Fighter (JSF) aircraft.

The newest class has an increased aviation capacity to include an enlarged hangar deck, realignment and expansion of the aviation maintenance facilities, a significant increase in available stowage for parts and support equipment, and increased aviation fuel capacity.

With the Rise of the LHA 6 comes the retirement of the Tarawa Class LHA, Someone however wants to extend the life of one of these Gator Carriers. The Coalition of Hope has a neat Idea. They want to repurpose the former USS Nassau.

Strip out all the Weapons, refurbish her, Paint her like a hospital ship and use her as a amphibious aid platform. this makes a lot of sense as the mission profiles of Amphibious assault and Humanitarian disaster relief are actually almost identical case in point the Philippines right now.

I read about this.

But, frankly, I do not see it happening. Unless it were operated by the US Military (or perhaps one of our closest allies), I just do not see the US military agreeing to take one of our heretofor front line vessels, which is still a very capable design, and open it up this way.

Maybe Obama will do it...but I would council strongly against it.

They could build a commercial vessel for the price of the upgrade/refit and it would be a lot cheaper to operate.

Presumably the navy could operate it as part of the auxiliary fleet like the RoRo transports and oiler's. In the end though I suspect you are likely correct that a commercial design would be used.

So, turn it into a USNS instead of a USS?

That would entail that they meet some very specific requirements.

Is that what the Coalition of Hope is proposing?

Somehow I do not think so.

Especially when I read their proposal to make it available to a, "partnership with a broad coalition of nations, Non-Governmental Organizations (NGOs) and others", I shudder to think who all would be onboard and operting it. They even say they want to retain the vast Command and Control capabilities of the vessel to direct other assets.

Anyhow, the vessel was built to military combat standards, and has a lot of sensitive military technology built into it, even if you take the weapons and combat sensors off of it, including:

The entire well deck design and functioning
The design and layout of the vehicle decks
The Hanger spaces
The Elevators
The Command and Control spaces
The Structutre of the vessels right down to its its ballast arrangement
etc.

I just do not see the US military signing up for making that available to civilian crews involved specifically in those kind of missions.

I guess we will wait and see.
