Tecnologie e innovazioni in campo navale
Ships that repair themselves best line of defence

Citazione:The research led by RMIT University’s Professor Adrian Mouritz and funded by the Australian Department of Defence and the US Navy, effectively allows ships to repair themselves while at sea.
Partnering with CSIRO, Mouritz is developing a polymer that can be squirted onto cracked or damaged fibre composite surfaces to repair them within 10 minutes.
“At the moment, if you damage a composite, whether it's an aircraft, a naval ship, a wind turbine blade or anything, you need to take it out of service, so you can't use it," he says.
“You've got to cut out, or grind out the damaged area and then put new material in, and that's a pretty slow and expensive way to do it.
“Our method allows you to do repairs immediately when the damage forms and it can heal itself in the same way that your body does.”
Preserving defence fleets is critical work, but protecting personnel is even more important. Fires on ships at sea or while docked can threaten lives, not to mention millions of dollars in infrastructure.
The research aims to prevent blazes like the one that destroyed HMAS Bundaberg, a $54 million navy patrol boat, in 2014...

RE: Tecnologie e innovazioni in campo navale
Un concetto innovativo decisamente importante, a mio modo di vedere, per qualsiasi Marina moderna, non solo per l'US Navy:

The future of the US surface fleet: One combat system to rule them all

Citazione:As the U.S. Navy’s surface fleet moves into 2019, a radical shift is coalescing among its leaders: a move away from a model that has driven the way the service has built its ships for decades.
When the Navy built its Arleigh Burke-class destroyers, installing the Aegis combat system into the hull meant a large suite of hardware — computers, servers, consoles and displays — designed and set up specifically to run Aegis software. Any significant upgrades to the suite of systems already installed, or to the Aegis system in general, required cutting a hole in the ship and swapping out all the computers and consoles — a massively expensive undertaking.
And what’s more, Aegis isn’t the only combat system in the fleet. Raytheon’s Ship Self-Defense System runs on many of the amphibious ships and the Ford-class carriers. Both classes of littoral combat ship run different combat systems, one designed by Lockheed Martin and the other by General Dynamics. And in regard to the ships themselves, there are multiple, siloed systems that don’t feed into the main combat system.
If Navy leaders get their way, that’s going to change.
What the surface fleet wants is a single combat system that runs on every ship, and runs everything on the ship, and that doesn’t mind what hardware you are running so long as you have the computing power for it.
The goal here is that if a sailor who is trained on a big-deck amphibious ship transfers to a destroyer, no extra training will be necessary to run the equipment on the destroyer.
“That’s an imperative going forward — we have to get to one, integrated combat system,” Rear Adm. Ron Boxall, the chief of naval operations’ director of surface warfare, said in a December interview at the Pentagon with Defense News.
Boxall describes the current situation to an integrated combat system as the difference between a flip phone and an iPhone. When buying a flip phone, most of the hardware and software are already included, leaving you with a limited ability to upgrade the phone. And if you want to run more advanced applications, you need a new phone. Instead, Boxall wants the combat systems to run like the iPhone...

On a ship, that means that if the Navy adds a new radar, missile or laser, the software that runs the new equipment is developed as an application that interfaces with the single integrated combat system, the way Waze integrates with the iPhone or Android software.
This has the benefit of having everything linked into the central nervous system for operators in the combat information center, sonar control, on the bridge or in the ship’s intelligence-gathering center. It also means that new systems are quickly integrated, skipping the expensive process of ripping out old servers and consoles.
And it means the companies that develop the myriad combat systems in service today — say, Raytheon or Lockheed Martin — won’t have a lock on developing software for Navy ships because the Navy wants the combat system to be developed with interfaces that are accessible by outside application developers.
“We need to continue down the path to be more aggressive and get a lot more competition in the open-architecture space,” Boxall said...

RE: Tecnologie e innovazioni in campo navale
Sicuramente nell'ambito della difesa è un concetto impegnativo da applicare . Ma è sempre un buona base di partenza per ragionarci.
Il soldato prega più di tutti gli altri per la pace, perché è lui che deve partire e portare le ferite e le cicatrici più profonde della guerra.”
