You do not need high speed to have high maneuverability. WW I era fighters are still among the most maneuverable platforms.

Maneuverability is the ability to exploit to the maximum whatever speed you CURRENTLY have. That is why modern avionics requires so much in-flight data BEFORE calculating a surface displacement command. All of this processing is near instantaneous and transparent to the pilot.

Its not that Ramjet will function throughout the journey , it could be used for terminal phase too but then terminal phase will be supersonic/hybersonic. However , if RAAD uses ramjet from launch till hit then the whole journey would be hypersonic. Plus raad's body is not that type of

China achieved a breakthrough development for high-speed missiles equipped with a new high-technology ramjet engine, according to state media.
The breakthrough was based on two successful flight tests of a solid-fuel ramjet capable of producing hypersonic speeds—4,000 miles per hour or faster, according to a May 31 report in Science and Technology Daily, official newspaper of the Chinese Ministry of Science and Technology.
The new engine is part of China's second type of hypersonic missile—weapons designed to defeat missile defenses.
The first hypersonic weapon, known as the DF-ZF, is a strike vehicle that glides and maneuvers to its target at speeds of up to 7,000 miles per hour. China has conducted six tests of the DF-ZF, according to Pentagon officials.
A ramjet is a high-speed engine that must be launched from missiles or aircraft that then accelerates. It is designed to use its forward propulsion to assist efficient fuel combustion in producing hypersonic speeds.
Hypersonic weapons are deadlier than slower missiles because of the ability to maneuver at very high speeds, making detection, tracking, and targeting by missile defense sensors and interceptors very difficult.
China's hypersonic weapons, which have been in development for more than a decade, were mentioned Monday by Marine Corps Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, as one of the several growing threats posed by China's military.
Dunford said during congressional testimony that the Chinese "have expanded their nuclear enterprise and made investments in power projection, space, cyber, hypersonic weapons, cruise missiles, and ballistic missiles—even as they continue to build out their physical presence in the South China Sea."
It was the first time the chairman mentioned hypersonic weapons in discussing military challenges from China.
Defense Secretary Jim Mattis also voiced concerns about growing hypersonic missile threats during a House Armed Services Committee hearing Monday night.
Asked about Russia's recent test of a Zircon hypersonic cruise missile and Chinese hypersonic missiles, Mattis said the weapons represent one of the new dangers posed by rapid technological change. "I think we have got to increase our hypersonic R&D effort," he said.
The Washington Free Beacon first reported Chinese development of a new ramjet powered hypersonic missile in 2014. The report included a drawing of the missile.
According to recent Chinese reports, the new ramjet engine involves a variable airflow and is expected to enhance missiles carried by China's J-20 fighter, as well as hypersonic missiles.
The technology breakthrough was made by a research team from the No. 4 Research Institute under the China Aerospace Science and Technology Corporation.
Based on the two successful flight tests, development of the ramjet will advance to the next phase of engineering, "paving the way for China's next generation of hypersonic missiles," Science and Technology Daily reported.
The engine has been under development since 2000 and was described as a low-cost, high power, and high controllability propulsion system in a compact form. A total of eight flight tests have been carried out.
Song Zhongping, a military expert formerly with the People's Liberation Army Rocket Force, told theGlobal Times that the new engine will give J-20 jets the ability to fire missiles to great ranges and at hypersonic speeds.
Ramjet-powered anti-aircraft missiles will have ranges of up to 186 miles at speeds faster than Mach 5, or more than 4,000 miles per hour.
The engine likely will be deployed with China's more advanced missiles including the PL-12 air-to-air missile, which currently has a range of 62 miles.
Hypersonic missiles cannot be countered by U.S. missile defenses because of their extremely high speeds.
Future uses include development of ramjet-powered cruise missiles and unmanned aircraft.
The Pentagon's annual report on China's military said hypersonic weapons are one of several arms that Beijing is investing significant resources in developing.
The weapons are being developed to counter U.S. ballistic missile defenses, the report said.
An Air Force-sponsored study made public last year warned that the United States is facing a growing threat of attack from hypersonic missiles.
"The People's Republic of China and the Russian Federation are already flight-testing high-speed maneuvering weapons (HSMWs) that may endanger both forward deployed U.S. forces and even the continental United States itself," an executive summary of the report stated.
"These weapons appear to operate in regimes of speed and altitude, with maneuverability that could frustrate existing missile defense constructs and weapon capabilities."
Gen. Mark Milley, Army chief of staff, told a Senate hearing June 7 that the service and the Pentagon are "progressing on the development of hypersonic munitions."
"Not only missiles, but bullets as well," Milley said, adding that funds are being devoted to research and development.
The budget request for fiscal 2018 contains $75 million for software modification to current ballistic missile defenses to deal with hypersonic threats.

A news report on the Chinese CCMF channel has revealed a glimpse of a top-secret JF-12 hypersonic wind-tunnel in which prospective - and presumably military - hypersonic aircraft are being tested.
Aerodynamic tunnels are commonly used to test the properties of machines prior to full scale production. In the case of aircraft that tend to be big and expensive, small models of new plane designs are positioned in wind tunnels to reveal how the new craft withstand high winds.
In the case of hypersonic planes, a tunnel is required that can simulate an aircraft movement at speeds much faster than the speed of sound. China has now demonstrated their own version.
Built in 2012, the JF-12, dubbed ‘Hyper Dragon,' has been a carefully kept secret. The 2.5 meter wide, 265 meter long installation reportedly cost almost $7 million to construct and is capable of creating wind speeds up to 10 times the speed of sound, or about 7,680 mph. At those speeds, the air temperature in the tunnel can reach 5400 degrees Fahrenheit, testing the impact of hypersonic travel on structural materials.
Now, Chinese CCMF cameras have revealed a glimpse of several machines currently being tested in the hypersonic tunnel.
One futuristic hypersonic aircraft is an arrowhead-shaped glider which observers believe to be a model of the DF-ZF, previously known as WU-14.
China military and tech observers believe the machine to be capable of reaching 10 times the speed of sound, in what would be a serious challenge to current air and missile defense systems.
"The combination of high speed, maneuverability, and relatively low altitude makes them challenging targets for missile defense systems," said a report by the US National Air and Space Intelligence Center released during the summer.
Another study, quoted by the Free Beacon, details that "These weapons appear to operate in regimes of speed and altitude, with maneuverability that could frustrate existing missile defense constructs and weapon capabilities."
While there are numerous artist versions of what the DF-ZF could look like, the CCMF images are the first time China has revealed details of hypersonic planes. The image shows an aircraft model that looks very much like a paper plane, but folded with steel instead of paper.
The video shows other hypersonic vehicles of various shapes, including a triangular-shaped glider, and one weapon that appeared similar in shape to the last stage of a ballistic missile.
According to a DeathRattleSports report, a scientist in the video — Jiang Zonglin — never mentions the potential military application of the Hyper Dragon. Instead, Jiang explains that China is developing a commercial aircraft that could connect Beijing to New York in just two hours, seven times faster than today's air travel.
Jiang also details that the JF-12 tunnel conducts its tests every two days, and each test lasts only one-tenth of a second.
However, US officials do not seem to be too concerned about the upcoming challenges.
"Hypersonic technology is concerning to me, but it's really no more concerning to me than any cruise missile technology, any ballistic missile technology," said Air Force General John Hyten, commander of the Strategic Command, in July.
"We have to be prepared to defend ourselves against all those threats. And we have to have a deterrent that is ready to respond in case any of those break out," Hyten added.

JF-12 is the name of the tunnel, not the name of the aircraft. Either way the news sounds like B.S.

No, JF-12 is China's Hypersonic Wind Tunnel @Basel
@Martian2 @JSCh @52051 @GS Zhou
CHINA'S JF-12 HYPERSONIC WIND TUNNEL
The JF-12 Hypersonic Wind Tunnel began operations in March 2014. It is the world's largest hypersonic wind tunnel, capable of achieving speeds of Mach 5 to Mach 9.
Along with the successful hypersonic glider vehicle WU-14 tests (which demonstrated Chinese capability in working high strength, thermal resistant aerospace materials), China has the world's largest hypersonic wind tunnel, the JF-12.
The JF-12 can produce speeds of up to Mach 9 (NASA's hypersonic wind tunnel reaches to only Mach 7). The JF-12 would provide Chinese scientists with a convenient way to observe supersonic airflow of different scramjet configurations, in addition to directly testing material durability in laboratory conditions, rather than having to make difficult and expensive high-altitude engine test flights.
