Do any Chinese members have information on the acquisition and tracking of ships for the DF-21D ASBM?
Does it use ground based radars? If so, what type?
Does it use GPS?
Does it use drones/maritime patrol aircraft, if so, what type?
Does it use spy satellites? If so, how many and what are their details (weight, orbit).
Sorry for all the questions. Promise I'm not a spy

The number of satellite put into space is only second time to USA. Not even Russia has as much workable satellite as China. From the latest 5G broadband satellite to the most secure quantum satellite. They are all made in China

GPS, INS, (probably star patterns matching in emergency) and active radar terminal homing system. Main challenge is how to find and track target, and damage assessment.

I doubt it depend on Beidou/GPS, most likely an active homing radar seeker (DF-21 has a payload of over 2000kg, so there is sufficient room to fit a powerful radar), as for the early targeting, it is actually the most critical/advanced part of the system, it may depend an network, including OTH radar/ocean observation satellite/long range UAVs/undersea sonar array to provide a robust long range targeting and detecting network.
With DF-21's speed and large warhead (to accommodate powerful active homing seeker), I doubt DF-21AShBM need mid-course position updating, they may only need a early targeting input through the large network and fire-and-forget.

‘Falling behind’: US admiral warns of China dominance in hypersonic missile race
Weapons under development by China and Russia – as well as by the United States – can fly at many times the speed of sound and are designed to beat regular anti-missile defence systems.
PUBLISHED : Friday, 16 February, 2018, 12:25pm
Even as the Pentagon hustles to ensure that its defences keep pace with North Korea’s fast-growing rocket programme, US officials increasingly are turning attention to a new generation of missile threat.
These weapons under development by China and Russia – as well as by the United States – can fly at many times the speed of sound and are designed to beat regular anti-missile defence systems.
The hypersonic missiles could change the face of future warfare, as they can switch direction in flight and do not follow a predictable arc like conventional missiles, making them much harder to track and intercept.
“China’s hypersonic weapons development outpaces ours … we’re falling behind,” Admiral Harry Harris, who heads the military’s Pacific Command, warned lawmakers on Wednesday.
“We need to continue to pursue that and in a most aggressive way to ensure that we have the capabilities to both defend against China’s hypersonic weapons and to develop our own offensive hypersonic weapons.”
In its proposed US$9.9 billion requested budget for 2019, the Missile Defence Agency (MDA) is asking for US$120 million to develop hypersonic missile defences, a big increase from the US$75 million in fiscal 2018.
MDA Director of Operations Gary Pennett told Pentagon reporters this week that the potential deployment by America’s rivals of hypersonic weapons – which could be launched from planes, ships or submarines and carry either nuclear or conventional payloads – would create a “significant” gap in US sensor and missile interceptor capabilities.
“The key challenge to US national security and the security of US friends and allies is the emergence of new threats designed to defeat the existing” ballistic missile defence system, Pennett said.
So, why the sudden alarm?
According to reports in the Japan-based Diplomat magazine, China has developed – and last year tested – a new type of hypersonic missile called the DF-17. The US Office of the Director of National Intelligence this week stated China “has tested a hypersonic glide vehicle”.
Russia too is believed to be developing its own hypersonic weapon called the Zircon. According to Russian news agency Tass, it is to go into serial production this year.
Though the Pentagon is warning about hypersonics, the United States has been developing the technology for years.
The Air Force says its X-51A Waverider cruise missile, tested in 2012, could travel at speeds faster than Mach 6 (3,600 miles per hour, 5,800 kilometres per hour).
That is more than one mile a second, and future iterations are expected to go much faster.
Part of the reason China has been able to advance its hypersonic missile programmes is that it is not subject to anti-missile treaties signed between the United States and Russia.
The 1987 Intermediate Nuclear Forces Treaty banned short- and intermediate-range ground-launched missiles.
“Over 90 per cent of China’s ground-based missiles would be excluded by INF if they were now in it,” Harris said.
Still, by far the lion’s share of the MDA’s budget continues to go towards improving existing missile-defence systems.
Various sensors and radars can track an incoming missile hurtling towards a target, then blast interceptor rockets toward it to pulverise it with kinetic energy.

Hypersonic missiles: China’s lead prompts Pentagon call for new defence systems
CHINA’S development of “hypersonic” missiles has the United States deeply worried, with calls for urgent funding to catch up in the high-stakes arms race.
Jamie Seidel
News Corp Australia NetworkFEBRUARY 19, 201812:48PM
IT’s another example of the game of military leapfrog played ever since the first caveman hefted a rock.
Others immediately start looking for a better weapon.
It’s happening again.
The United States is concerned it has lost the technological edge when it comes to a new arena of warfare: hypervelocity missiles.
These are themselves a response to the increased capability of modern defensive systems.
Cruise and ballistic missiles can now be targeted. Ship, ground and air launched interceptors can destroy them before they reach their target. And even if they get close, radar-guided robotic gattling guns have a last-ditch chance of knocking them from the sky.
What makes a hypervelocity missiles so potent is they are fast.
Very fast.
So fast neither interceptor missile or bullet has enough time to act.
Late last year China declared it was on the brink of putting operational examples of this new weapon system into service.
The United States isn’t.
And that has The Pentagon worried.
EXPLORE MORE: Beijing ‘perfects’ new hypervelocity missile
”China’s hypersonic weapons development outpaces ours ... we’re falling behind,” Admiral Harry Harris — soon to be the next US ambassador to Australia — said late last week.
“We need to continue to pursue that and in a most aggressive way in order to ensure that we have the capabilities to both defend against China’s hypersonic weapons and to develop our own offensive hypersonic weapons.”
A CALL TO ARMS
A US Missile Defence Agency report reveals it has placed an urgent call to its suppliers for improved sensors capable of detecting — and tracking — hypervelocity missiles in flight.
It’s called for a new $9.9 billion budget for 2019.
It recognises the urgent need to improve its defences against this emerging threat.
Enormous nuclear-powered aircraft carriers suddenly seem vulnerable.
RELATED: ‘How the US will lose the next war’
Large but static strategic bases — such as Guam in the middle of the Pacific Ocean — have little chance of countering such an attack.
Which is why Missile Defense Agency Director of Operations Gary Pennett told reporters during a recent budget briefing that it has identified “sensor and interceptor capability gaps”.
“The key challenge to US national security and the security of US friends and allies is the emergence of new threats designed to defeat the existing ballistic missile defence system,” he said.
In particular, he was worried about the speed of command and control networks needed to isolate the threat, and to inform units capable of doing something about it.
Where once they had minutes, they now have just seconds.
“Any software associated with any of those systems might have some capability to track hypersonic systems. This evolving threat demands a globally present and persistent space sensor network to track it from birth to death,” Pennett said.
DELVE DEEPER: Beijing has already won the South China Sea
The budget appeal comes just months after Chinese state media reports it had successfully tested hypersonic warheads and was now moving on to full-scale production.
This may have a lot to do with the US Missile Defence Agency’s new plans to install 64 Ground Based Interceptor facilities around the United States before 2023.
But North Korea is also another motivator.
ACHILLES HEEL
Chinese state media has boasted of the success of its new type of hypersonic missile, designated the DF-17. The US Director of National Intelligence has confirmed these tests actually happened.
Beijing may have achieved this lead as it is not subject to the same international arms control treaties as Russia and the United States.
EXPLORE MORE: Can China already beat the US?
But Russian state media has been making similar claims. It says its first example of the new technology will enter production later this year.
This looming new threat may explain the a US emphasis on improved detection and response systems: these target the one weak point hypervelocity missiles retain.
They need to be boosted into space.
Like intercontinental ballistic missiles, a large rocket must lift the warhead off the ground and propel it high into orbit. The higher and faster it is going when it reaches the top of its parabolic arc, the faster it can dive back into the atmosphere below.
From that point, things get difficult.
The smaller warhead glides at more than 6000km/h. But it can also twist and turn to avoid detection and incoming fire.
So, like ICBMs, shooting it down during its heavy-and-slow launch phase is the easiest option.
And for its deadly fast glide phase, the earlier it is detected — the greater the chance of calculating a shoot-down solution.
Both need reliable information, fast.
Thus the emphasis on researching new long range / high accuracy sensors and command-and-control processes.
But also in the works is a redesigned ‘kill vehicle’ interceptor warhead, improving the chances of taking down a high-energy opponent.
