Recent US Hypersonic development.

[Resasi]

Recent Russian and Chinese hypersonic weapon development, Avangard, Kinzhal, DF-ZF, and Starry Sky 2, would seem to have resulted in Lockheed Martin being awarded projects to develop two new hypersonic weapon systems.
Lockheed Martin claims both USAF hypersonic programmes

$480 million for the AGM-183A Advanced Rapid Response Weapon ARRW, or Arrow a continuation of DARPA’s Tactical Boost Glide program rocket carried aloft by an aircraft such as a B-52 bomber with a projected top speed of up to Mach 20,or around four times faster than Russian and Chinese hypersonic weapons.
Kinzhal.
Starry Sky 2 is a Chinese development of a hypersonic aircraft that could fire nuclear missiles at up to six times the speed of sound. With intended speeds of up to 4,563 miles per hour, and ability to rapidly switch directions mid flight. Launched from a multistage rocket it continues to move at about Mach-5.5 for 400 seconds as a wave-rider surfing on the shockwaves of its own supersonic lift.

$980 million will be for work on Hacksaw or HCSW Hypersonic Conventional Strike Weapon solid fuel rocket with GPS guidance.

And on the HAWC or Hypersonic Air-breathing Weapon Concept using scramjets for hypersonic cruise which the USN may have been testing.

Hypersonic weapons are the latest weapons coming in two types: boost glide weapons and powered atmospheric weapons. Boost glide weapons Arrow, Tactical Boost Glide Hacksaw—are unpowered weapons boosted to high altitudes by rockets and released to glide down to target at hypersonic speeds and powered atmospheric weapons using scramjets for propulsion.

Hypersonic’s extremely high speed shortens defender’s reaction time, their speed and flight profile making it difficult for conventional air and missile defenses to intercept. Boost glide weapons are released at very high altitudes but stop short of entering space like a ballistic missile warhead.

Tactical Boost Glide attacks enemy conventional targets near the front line,headquarters units, air defense missiles, ballistic missiles, important, mobile target. While Hacksaw with a longer range attacking targets across continents. Arrow, without conventional or tactical in the name, suggesting possibly a nuclear delivery system.

Will be a game changer if they can be implemented reliably.

The whole Decision making chain will have to become faster, probably negating any role for humans.

Roll on laser hard kill to counter these although the K.E alone will bring dumb warheads back into fashion.

According to your own links, the Russians already have mach 20 hypersonic weapons, the Avangard. US plans are to start to develop missiles which are equivalent to ones that the Russians already have. They will be in two categories. One is a short to medium range missile that will do mach 5. The other is a very long range (strategic) missile with a warhead that can do mach 20. These match Russian and Chinese (there is less certainty as to what they have) developments, but the US is at least half a decade behind.

The major problem that I see for the US (aside from being behind in technology) is that their missile defence plans were centred around missiles following predictable ballistic trajectories. According to your links the mach 20 manoeuvrable missiles render those missile defence plans obsolete. There goes a crap load of money and plans down the drain.

If one can believe Russia’s statements on their anticipated capabilities.

aside from being behind in technology...etc etc

Quite an assumption to make some might say. But of course if the Avro Arrow were to be resurrected no doubt all would be well.

This was from one of your links. If you question some of the references you used then perhaps you might want to go into detail on each one as to what parts of your links you find questionable and which parts you don't.

What...and do you out of the chance to shine???

Meanwhile, Russia starts looking for a lost missile

And, to quote a well known ARSE authority. There goes a crap load...

Russia certainly believes it is way out ahead...or at least that what Putin is telling them.

They might have some trouble putting the team back together.

My father worked on that project.

And he died in 1980.


Aged 84.



Still, nice to see it get a mention though.

It was apparently very advanced for the time. Perhaps reminiscent of the UK’s TSR2.
