That's one odd design! It's conservative to the extreme, and made me assume Cessna simply had a lack of experience building high-subsonic airframes (not true, they have a line of business jets). The straight wing is less susceptible to aeroelastic phenomena like torsional divergence, at the expense of poorer performance at Mach numbers approaching 1.
All in all, it looks more like a tech demonstrator for the company than an actual product, as evidenced by the myriad of changes it has received in its short lifespan.

It isn't designed to be a fast interceptor, but a trainer. The ground attack feature is secondary as Super Tucano or other current jet trainers.

The reason of having such an odd wings is because it climbs better in lower speed than other generic supersonic configuration, as most of the non-supercruise fighters have with superior LO-LO and advance weapon system. Think it like a L-39 mated with F/A-18, and more focused on low altitude.

They didn't build the Scorpion for a U.S. trainer and was withdrawn from the future trainer program, as it would have had to be modified. Its a light attack and intelligence, surveillance, and reconnaissance aircraft. There are interested countries but no one wants to be the launch partner. Textron would also like to offer it to the Air National Guard.

What I said, it's not designed for high speeds. The L-39 is said to have a never exceed Mach of 0.8 (source: wiki, call me lazy), so it's firmly grounded in it's low-subsonic envelope, whereas the F/A-18, while having some nods to subsonic flight in it's design, is conditioned by it's supersonic requirements.
And as evidenced by their lack of customers, I'm not the only one skeptical of that design being mature enough for adoption :/

No, it was pretty much just meant to be a budget tactical jet. Basically to fit in somewhere below an F-16/A-10 but above a UAV. It's per hour cost is around $2200 which is remarkable especially when compared to the F-16 ($22,000+) and even the cheap A-10 ($17,000).

To quote wikipedia:
"The aircraft is intended to handle mission profiles typically performed by the U.S. Air National Guard, including domestic interdiction, quick-reaction natural disaster support, air sovereignty patrols, and low-threat battlefield missions"

Further Qualification Trials for USMC V-22 Osprey and French Navy Mistral-class LHD

quote:

The French Navy (Marine Nationale) announced that it took another step in the interoperability between the V-22 Osprey and the Mistral-class LHD Dixmude on May 2nd 2016. While V-22s have been tested with the Mistral-class several times to date (they were even officially qualified with the Mistral-class last year) it is the first time that the Bell-Boeing tilt-rotor aircraft was qualified for "blades and wings folding and long time parking" aboard the French Navy LHD.
...
According to the French Navy: "all these capabilities will enable to achieve operational interoperability to transport troops or logistical supply, similar to the C2 Greyhound on the aircraft carrier Charles de Gaulle".
...
Similar qualifications are expected to take place on board aircraft carrier Charles de Gaulle.

I am convinced the French Navy really wants the bird... but can't afford it.

Brings back some bad memories.

Had the opportunity to work with another division of Boeing which was perfectly willing to devise ways to consume all research and development funds to demonstrate it can address what a customer says it wants, but had difficulty designing for production in a manner that made the end result affordable.

Research and development funding is inherently risky, and because it is so, has less empirical constraints placed on it to measure a meaningful cost to value ratio benefit by its expenditure (sometimes you have to take a chance on experimenting with something only to find out it doesn't lead to an effective design within available production cost constraints).

Boeing had a way of making even the most improbable appear possible until the last nickel of R&D funding has been consumed.

Given the issues on Osprey with control during transition from take off to flight, and particularly landing, I can only imagine what changing the design and balance to account for folding wings and rotors does to the vortex ring state which almost killed the project in first decade of 2000.

Not sure if there is enough information yet to add Australia's Shortfin Barracuda (replacement for Collins-class; service dates: 2030-) to the database, but it certainly makes interesting reading...

That would make a lot of sense, given how we use the MV/CV-22s in Africa (crisis reaction) and how France operates in Africa. It'd be interesting to see how a unit of Ospreys could have been used by the SERVAL forces, especially during that initial period. Would it have made a difference?

I wonder if add-on capabilities for the Osprey, such as the Marine Corps' roll-on refueling or the hypothetical ASW/AEW/Gunship packages might further tempt the MN.

http://www.janes.com/article/60388/china-proposes-underwater-great-wall-that-could-erode-us-russian-submarine-advantages?



quote:

China proposes 'Underwater Great Wall' that could erode US, Russian submarine advantages

The China State Shipbuilding Corporation (CSSC) has proposed the construction of a network of ship and subsurface sensors that could significantly erode the undersea warfare advantage held by US and Russian submarines and contribute greatly to future Chinese ability to control the South China Sea (SCS).

Details of the network of sensors, called the 'Underwater Great Wall Project', were revealed in a CSSC booth at a public exhibition in China in late 2015. A translated copy of the descriptions was obtained by IHS Jane's from a government official. The text was confirmed by a source from a second government on condition of anonymity.

While some elements of this network have been known for some time, CSSC is now in effect proposing an improved Chinese version of the Sound Surveillance System (SOSUS) that for a time gave the US a significant advantage in countering Soviet submarines during the Cold War. The system proposed by CSSC is likely being obtained by China's People's Liberation Army Navy (PLAN) but may also be offered for export.

CSSC says that, among other things, its objective is to provide customers with "a package solution in terms of underwater environment monitoring and collection, real-time location, tracing of surface and underwater targets, warning of seaquakes, tsunamis, and other disasters as well as marine scientific research".

The corporation says in the document that its "R&D and production bases in Beijing and Wuxi [have] the ability to support the whole industry chain covering fundamental research, key technology development, solution design, overall system integration, core equipment development, production, and operation service support".

The shipbuilding conglomerate says it has 10 series of products on offer that include systems relating to marine observation, oceanographic instrumentation, underwater robotics, and ship support.

Specific components of CSSC's surveillance system include surface ships, sonar systems, underwater security equipment, marine oil and gas exploration equipment, underwater unmanned equipment, and marine instrument electronic equipment.


More or less expected that the Sino-SOSUS that has been under construction since the late 2000s now will evolve into an actual undersea battle network.
Shore based ASW missile launchers have been presented as well during the last Zhuhai Airshows, and the artificial islands would be perfect for command and control of the Underwater Great Wall.

Kinda creepy how they adopted the Hollywood style console interface, with some seriously detailed monitoring informations (in English as well, that means they are looking for foreign customers too).

If China is really mature with datalinks and system integrations, then the only limit with be users themselves -- If we ever have a chance to see how they work their whole system rather than vague advertisements.

And I hope the Chinese spelling is better than the English spelling..."suspecious"

That screenshot looks more like one you would see in the movie Spaceballs on one of the fake displays. It looks like someone who works in a corporate IT environment would think a military display would work. A little disappointed that Jane's wouldn't call BS on something like this.

Yeah my take is its a little over the top.

Look at a map and where Chinese bases, territory and friendly ports are and you can see the problems with replicating the NATO SOSUS system. AKA. Their problem isn't technical but geographical one with the exception of the Bay of Bohai and few points around Hainan. You need to be able to wire up chokepoints and access points but the Chinese don't really have many places they can do that.

My guess is they're developing very good UUV, local array systems etc. which would make more sense for them.

Well, I wouldnt fixate too much on the graphical advertizing. Chinese military products are usually advertized in very very cringeworthy way, which reflects the general lack of Chinese media savvy in all things, as well as the secretive nature of their MIC. Remember the top-gun footages in the PLAAF recruitment ads, meant to show PLAAF life-fire excercises against 'plane-like' target drones? That's so typical of China for you. But all this does not mean that the PLAAF doesnt do life-fire excercises against drones and drone-fied planes at all. It just means that the PLAAF propaganda bureau are pretty incompetent and not media savvy enough.


There are indications that a sino-SOSUS is already established in parts since the late 2000s, and in previous weapon shows, there are some key components presented individually. Each of them would fit into this "underwater great wall" plan.

Some key components would be the fiber-optic hydrophones presented in 2014, the WS-3 based shore-launched ASROC MLRS, the UUVs and surface drones etc, among things.

As mik mentioned, logistic issue for SOSUS can still render it expensive and difficult to deploy. Even they can bypass all the geopolitical issues to deploy it, the maintenance and counter-sabotage operations only cause more trouble than it's worth.

Mobile UW monitoring is developing as they understand the static sensors can be avoided or sabotaged, and SOSUS should be just a supplemental measure to control the sea.

No technical mystery in sub-launched UAV-submarine communications. For some time thinking on this issue, but it's not a new advanced communications system breakthrough.
At last is only a simple radio link with a submarine surface-piercing mast antenna, increasing the submarine exposure and vulnerability (very probably employed submerged in the VLF/LF receiving-only function):
