Abstract: This talk will follow (click here) on to the webinar Cameron Tracy gave in this series last October, which was based on this paper:
http://scienceandglobalsecurity.org/archive/sgs28tracy.pdf
The current webinar will begin by discussing the evolution of the US hypersonics program and its mission since 2000. This shift in mission has led to programs to develop hypersonic weapons having ranges up to a couple thousand kilometers, rather than the longer range systems envisioned previously. The talk will discuss how the technical issues raised in the above paper for longer range hypersonic weapons apply to these shorter range systems. One focus will be on what is required for these weapons to evade missile defenses, and how that can affect their detectability to satellite sensors....
In other words, the big hurdle is STEALTH technology to hide the high heat that betrays them today. The USA, Australia and the UK also have to decide how and where they fit into the current "Nuclear Triad."
There is no mystery to this. The USA simply has to test it and perfect it's flight.

The US, UK and Australia (click here) will co-operate on the development of hypersonic weapons, expanding a trilateral security pact designed to help Washington and its allies counter China’s rapid military expansion.
US president Joe Biden said in a statement with Australian prime minister Scott Morrison and UK prime minister Boris Johnson that the allies would enhance co-operation in several areas, including hypersonic weapons as part of their commitment to “a free and open Indo-Pacific”.
“We also committed today to commence new trilateral co-operation on hypersonics and counter-hypersonics, and electronic warfare capabilities, as well as to expand information sharing and to deepen co-operation on defence innovation,” the three leaders said in a statement that was released after the Financial Times first reported the pact.
“These initiatives will add to our existing efforts to deepen co-operation on cyber capabilities, artificial intelligence, quantum technologies, and additional undersea capabilities,” they added.
The push to co-operate on the development of hypersonic weapons marks the latest effort to increase the partnership between the three countries to counter the rise of China in the Indo-Pacific. Last year, the states signed a pact for the US and UK to help Australia obtain nuclear-powered submarines....
