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.

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.

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.
