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They didn't build the Scorpion for a U.S. trainer and was withdrawn from the future trainer program, as it would have had to be modified.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 :/

A failure attempt to make a trainer version of F-35, perhaps?

The trainer category is a cut-throat and risky market. [:)]

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"

Denmark CL-604 Challenger MPA Support NATO's Counter Piracy Operation Ocean Shield
Flying low over the waters near Somalia, Danish crews hunt for indicators of illegal activities across a wide stretch of ocean near the east African coast. While pirate attacks have been few in the last couple of years, the conditions which lead to piracy are still present and, as such, interested nations must remain vigilant. The Danish detachment is participating in part of a NATO effort that has been on going since 2008 to deter and disrupt pirate attacks...

Further Qualification Trials for USMC V-22 Osprey and French Navy Mistral-class LHD
Image
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.
Take care,

After the 40.000 tonne MLP, the next step is the 98k tonne MLP for the PLAN.
China just launched its 98,000t DWT Mobile Landing Platform (MLP).

COSCOL’s 98,000t DWT newbuilding semi-submersible vessel “Guang Hua Kou” was successfully launched on April 28th at Guangzhou Shipyard International (GSI). The “Guang Hua Kou” will be one of the largest vessels of its type when delivered end of this year.

I was browsing various websites and found this...

http://www.smh.com.au/federal-politics/ ... oeuxh.html
http://navynews.realviewdigital.com/#folio=2

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.
