Raytheon & Northrop Grumman successfully complete the second flight of a hypersonic missile prototype

Raytheon and Northrop Grumman, working in partnership, have successfully flown a hypersonic missile prototype for the second time in eleven months.

For the latest test, the HAWC prototype was carried under the wing of an aircraft and flown to high altitude, where it was released. A solid rocket booster then accelerated the vehicle to supersonic speed and a scramjet ignited. An engine without moving parts, a scramjet uses its forward motion to compress the incoming air into a shockwave that burns with fuel, producing enough thrust to propel the missile to over five times the speed of sound.

The latest prototype had only minor modifications from the previous flight and met all of its objectives. The data recovered by telemetry will be used to improve the digital models using artificial intelligence, machine learning, and big data, which will increase the efficiency and performance as the weapon concept comes closer to practical deployment.

As this is a military project, not many details about the prototype were released, such as its size, speed, design.etc. One shouldn’t even trust the illustrations of the missile, provided by Northrop Grumman. Each shows the missile with a rounded lifting body shape on its bottom side, likely to protect and guide it on its re-entry, but there is no guarantee the illustrations’ shape matches that of the real missile.

Did China test a hypersonic weapon in August?

On October 17th The Financial Times published a story claiming, based on anonymous sources, that one of China’s five launches in August tested a hypersonic weapon, which supposedly circled the globe to impact the Earth only 24 miles from its target.

The Financial Times story is behind a paywall, but not surprisingly it was picked up by much of the mainstream press, with the conservative press — as illustrated by this Daily Wire story — accepting the weapon as fact, while the leftist press — as illustrated by this CNN story — giving China the opportunity to deny the claim.

Did it actually happen? I have no idea. I would add however that I would not trust any story dependent wholly on anonymous sources, considering the unreliability of today’s press and the repeated evidence that numerous federal agencies in the military and intelligence communities routinely feed it disinformation for their own political purposes. These agencies, including the Space Force, want to encourage Congress to fund them, and creating a bogey man threat that the press can tout has for decades been the standard way to do it.

To get a better idea whether this hypersonic flight happened, let’s review the actual Chinese launches in August to see if any might be a likely candidate. For a launch to fit the description, there would have to be almost no information about its payload, and that payload would have to have not reached orbit, since the hypersonic test circled the globe once and then impacted the Earth.

Because of Russian violations, U.S. withdraws from nuclear arms treaty

The United States announced today that it is withdrawing from the 1987 Intermediate-Range Nuclear Forces (INF) Treaty because of numerous and long-standing violations by Russia.

[Secretary of State Mike] Pompeo explained that Russia has been violating the treaty for years, and despite those violations, the U.S. has attempted to maintain the agreement. “To this day, Russia remains in material breach of its treaty obligations not to produce, possess, or flight test a ground-launched intermediate cruise missile system with a range between 500 and 5500 kilometers,” Pompeo explained. “We have raised Russia’s noncompliance with Russian officials, including at the highest levels of government, more than 30 times, yet Russia continues to deny that its missile system is noncompliant and violates the treaty,” Pompeo said.

Pompeo said Russia’s violation of the treaty has compromised U.S. security interests. “It’s our duty to respond appropriately,” Pompeo said. “When an agreement is so brazenly disregarded, and our security is so openly threatened, we must respond.”

The announcement comes one day ahead of the 60-day deadline the U.S. gave Russia to return to compliance with the treaty.

The treaty calls for a six month period following this announcement for the withdrawal to be completed.

Though the announcement mentions a specific “a prohibited missile system,” it does not say what that missile system is. I suspect it might be the hypersonic missile the Russians have tested and say they will deploy this year.
