Hypersonic! It is all the rage. Seems everyone must have a hypersonic missile. See my most recent blog entry.
The Russians have one. The Chinese are reputed to have one. And now the USA has TWO of them!

"Northrop And Raytheon Have Been Secretly Working On Scramjet Powered Hypersonic Missile"
"Northrop Grumman and Raytheon have revealed that they have been working together on a scramjet-powered hypersonic cruise missile, which uses an engine that is entirely 3D-printed. Their design is competing against one from Lockheed Martin under the Defense Advanced Research Project's Hypersonic Air-breathing Weapon Concept program, or HAWC. The two companies publicly announced their partnership at the 2019 Paris Air Show on June 18, 2019, but they have been working together secretly for years on HAWC, according to Aviation Week"
AN ENGINE 3D PRINTED. PROBABLY USING SOME SORT OF PROPRIETARY METALS. JUST A FEW YEARS AGO NO ONE HAD EVEN HEARD OF 3D PRINTING. 3D PRINTING TOO NOW ALL THE RAGE?
