Does anyone have insight into the recent reports of Chinese "quantum radar"? I can't post links yet, but just google that to see the stories.
I'm by no means an expert, but the coverage has been basically technobabble. The only credible paper I've been able to find concludes that quantum radar can to 3dB better than conventional. That's not nothing, but hardly the game changer the news reports claim.
Only by few comments, because we still don't know both appearance and principle of the quantum radar. Only in theories on both US and China.
A quantum radar device could detect microwave reflections that would normally be swamped by the noisy background radiation. It would contain two devices capable of interconverting visible light with microwaves, a capability that exists with current technology. First the top converter couples two entangled beams, a microwave one (red wavy line) and a visible one (red straight line); then the microwave reflection is converted to visible light that interferes with the initial visible beam in the detector.
Here is the US publication in 2012:
https://www.phys.org/news/2012-12-quant ... radar.html
And the latest report about the development of Chinese QR, maybe this link is what you are referred:

Is it still unimpressed by the military, or just straight up propaganda? We still cannot judge anything about QR in short years yet.

Indian Navy 1st Scorpene-class Submarine Kalvari Tests SM39 Anti-ship Missile
The Indian Navy announced today that the crew of its first Scorpene-class submarine (Project 75) Kalvari successfully test launched and hit a surface target with an MBDA SM39 submarine launched anti-ship missile.
The missile in question is the SM39 Block II mod. 2 submarine launched anti-ship missile designed and built by MBDA. One of the unique feature and major advantage of SM39 is the ability for the crew to fire the missile deeper than periscope depth (at depths of 60 to 50 meters for example). Most similar weapons require the submarine to rise to periscope depth (15 to 20 meters) and therefore to potential danger before launching the missile.

Another design of Chinese solid fuel rocket, KT-2, conducted debut lift off with one experimental satellite:
https://www.nasaspaceflight.com/2017/03 ... -2-launch/
-snip-
The Xinhua news agency is identifying the new launch vehicle simply as ‘KT-2’. Other sources identify the new launcher as the Kaituo-2. Previously rumors expected that the new launch vehicle was the Kaituozhe-2A.
The Kaituozhe-2/Kaituo-2 launch vehicle is a three-stage solid propellant launch vehicle developed by the “CASIC Forth Bureau”. The new launcher is capable of orbiting a 350 kg cargo to LEO or a 250 kg cargo to a 700 km high SSO.
KT-2 has similar capabilities to the Kuaizhou-1A launch vehicle, that was used for the first time on January 9, 2017.

China's spokeswomen stated the military budget increasing rate will stay low at around 7%, possibly even smaller than 7.6% in 2016. Contradicted the optimistic increase expected by Chinese military reform, or to react with Trump's recently planned steep budget increase after the Ceremony of USS Gerald Ford in service:
Economy issue is expected, yet the improvement is way too significant of PLA modernization with 'limited' budget.

Japan May Have Tested its New XASM-3 Supersonic Anti-Ship Missile for the First Time
According to several witnesses from Japan (including open sources such as spotter pictures posted on Twitter), Japan's Ministry of Defense (MoD) has probably conducted the first live fire test of the new XASM-3 supersonic anti-ship missile. The Japanese MoD was originally planning to test the missile in 2016, as we reported in 2015, but not such test occurred last year.

XASM-3 looks stat wise to be kinda an analogue to the Kh-31A (or its slightly longer ranged update). Wonder if those are understated; cant imagine that Japan couldnt just made a supersonic AShM on base of the GQM-163 Coyote that they operate as well.

There appears to be a lot of controversy over the F35 strike fighter, as to its ability to fulfil its design criteria and/or to be ready to meet delivery dates?
Australia has purchased 72 F35s ($17 billion) with delivery commencing in late 2018 and 2 squadrons operating in 2020.
I hope we do not receive a plane which will not meet its full specification requirements on delivery and we are still paying for upgrades for the next 5 to 10 years to eventuality get the plane we paid for pre 2020.
Two F35s were in Australia for the Australian Government to show the fighter to the Australian public.
I was watching tonights ABC (Australian) news and they announced both planes were grounded as they could not fly in bad weather and they have to be returned to the US for modifications (hope this is incorrect).

Thanks for your perspective on the F-35 from down under [;)]. We are all concerned but realize the venerable F-16 and Osprey had teething pains. All costs and timelines are estimates on project of this magnitude. That said, the next year is very important for the F-35 since a lot of actual operational and tactical information from the joint exercises comes in.

North Korea escalates. Landed in Japan’s exclusive economic zone in the Sea of Japan. Japan’s top government spokesman, Yoshihide Suga, said at a news conference in Tokyo, calling the latest missile launch a “grave threat to national security.”

More likely the 'heinous accusation' of both Malaysia and South Korea spread the news of Kim cousin's killed by assassins sent by the dictator. To 'retaliate in anger' with missile tests.
But I am more inclined to determine the ability of counter-THAAD their missiles boasted, and ride along with China's recent economic rebuffs against South Korean companies under the US THAAD deployment and state-nationalism.

The Times broke a story last week that U.S. cyber attacks caused a few NK missiles to blow up on the launch pad over the last few years, my money would be that this is a reaction to that.
