Warrior Maven Video Above: How a Carrier-Launched Drone Will Change Carrier Attack Missions?
By Kris Osborn - Managing Editor - Warrior Maven
The Air Force is taking another step in an aggressive plan to prototype, test and deploy hypersonic weapons on an expedited schedule -- to defend against enemy attacks by fast-tracking an ability to launch high-impact, high-speed attacks at Mach. 5 - five times the speed of sound.
“We would like all the resources we can build into the kill chain to hit any target or hold it at risk with hypersonic weapons,” Gen . Timothy Ray, Air Force Global Strike Command, said at the Air Force Association Air, Space & Cyber Conference.
The service recently awarded a second deal to Lockheed to expedite prototyping of a hypersonic weapon, called the “Air Launched Rapid Response Weapon,” Air Force news reported.
The effort involves two separate trajectories, including the Air-Launched Rapid Response Weapon and a Hypersonic Conventional Strike Weapon. The Air Force has now awarded developmental deals for both systems to Lockheed.
The most recent award was cited recently in the service’s “Around the Air Force” new report, which said that Air Force Secretary Heather Wilson is “moving as fast as possible” when it comes to hypersonic weapons.
Recent thinking from senior Air Force weapons developers had held that US hypersonic weapons might first be deployable by the early 2020s. Hypersonic drones for attack or ISR missions, by extension, were thought to be on track to emerge in the 2030s and 2040s, senior service officials have told Warrior Maven.
Now, this aggressive new Air Force hypersonic weapons prototyping and demonstration effort is expected to change this time frame in a substantial way.
A "boost glide" hypersonic weapon is one that flies on an upward trajectory up into the earth's atmosphere before using the speed of its descent to hit and destroy targets, senior officials said.
The Hypersonic Conventional Strike Weapon effort involves using technologies which have not yet been integrated for air-launched delivery, an Air Force spokeswoman told Warrior Maven earlier this year.
Senior Air Force weapons developers have explained the rationale in terms of not waiting many more years for a "100-percent" solution if a highly impactful "90-percent" solution can be available much sooner.
Often referred to as "agile acquisition" by Air Force senior leaders, to include service Secretary Heather Wilson, fast-tracked procurement efforts seek quicker turn around of new software enhancements, innovations and promising combat technologies likely to have a substantial near-term impact. While multi-year developmental programs are by no means disappearing, the idea is to circumvent some of the more bureaucratic and cumbersome elements of the acquisition process.
A weapon traveling at hypersonic speeds, naturally, would better enable offensive missile strikes to destroy targets such and enemy ships, buildings, air defenses and even drones and fixed-wing or rotary aircraft depending upon the guidance technology available.

A key component of this is the fact that weapons traveling at hypersonic speeds would present serious complications for targets hoping to defend against them – they would have only seconds with which to respond or defend against an approaching or incoming attack.
In fact, while emphasizing the current Air Force push for hypersonic weapons, Ray raised this precise concern.
“The challenges becomes your ability to defend against hypersonic weapons - they are not easily defendable,” Ray told an audience at the AFA Conference.
Along these lines, the advent of hypersonic weapons is a key reason why some are questioning the future survivability of large platforms such as aircraft carriers. How are ship-based sensors, radar and layered defenses expected to succeed in detecting tracking and intercepting or destroying an approaching hypersonic weapon traveling at five-times the speed of sound?
Hypersonic weapons will quite likely be engineered as “kinetic energy” strike weapons, meaning they will not use explosives but rather rely upon sheer speed and the force of impact to destroy targets, developers explain.
A super high-speed drone or ISR platform would better enable air vehicles to rapidly enter and exit enemy territory and send back relevant imagery without being detected by enemy radar or shot down.
Although potential defensive uses for hypersonic weapons, interceptors or vehicles are by no means beyond the realm of consideration, the principle effort at the moment is to engineer offensive weapons able to quickly destroy enemy targets at great distances.
Scientists explain that speed of sound can vary, depending upon the altitude; at the ground level it is roughly 1,100 feet per second. Accordingly, if a weapon is engineered with 2,000 seconds worth of fuel – it can travel up to 2,000 miles to a target, a senior Air Force scientist told Warrior in a previous interview.
This hypersonic weapons acceleration is taking place within a high-threat global environment. Both Russia and China have been visibly conducting hypersonic weapons tests, leading some to raise the question as to whether the US could be behind key rivals in this area.
A report in Popular Mechanics sites Chinese State Media as having announced a successful test of a new “wave-rider” hypersonic vehicle.
“The hypersonic vehicle that detached from the booster rocket flew for 400 seconds, achieving a maximum speed of Mach 5.5 to 6 ( 4,200 to 4,600 miles an hour) and reaching an altitude of 100,000 feet,” the report says.
Also, a report in The Diplomat earlier this year outlines Chinese DF-17 hypersonic missile tests in November of last year.
In an essay from earlier this year titled “Hypersonic Missiles: A New Proliferation Challenge,” Rand scholar Richard Speier further specifies the seriousness of hypersonic missile threats.
“They are able to evade and conceal their precise targets from defenses until just seconds before impact. This leaves targeted states with almost no time to respond…..Hypersonic missiles require a reconsideration of traditional second-strike calculations, as they have the potential to decapitate a nation's leadership before it has the opportunity to launch a counter attack,” Speier writes.
