Worked on the X-30 National Aerospace Plane from 88-92. Yep. There are plenty of materials that will already take Mach 10.
See my book, “The Quest for the Orbital Jet.” (https://www.amazon.com/Hypersonic-Revolution-Studies-History-Technology/dp/1478146176/ref=sr_1_fkmr0_1?ie=UTF8&qid=1496250410&sr=8-1-fkmr0&keywords=The+quest+for+the+orbital+jet+Larry+Schweikart)
Note this edition says the author is the “US Government” Nope. (https://www.amazon.com/Hypersonic-Revolution-Technology-Aero-Space-1983-1995-ebook/dp/B00T0ZT214/ref=sr_1_1?ie=UTF8&qid=1496250248&sr=8-1&keywords=The+quest+for+the+orbital+jet)
In 2004 the X-43A reached mach 9.6 at 110,000 ft, which is hardly in the lower atmosphere. I’ve never heard anyone give a maximum speed for an aircraft (or missile) at sea level, where it would need to be to take out an aircraft carrier.
