Raytheon: The need for incredible speed - Accelerating the creation of hypersonic vehicles
The need for incredible speed
Accelerating the creation of hypersonic vehicles
Hypersonic vehicles operate at extreme speeds and high altitudes. Raytheon is developing hypersonics for the U.S. Department of Defense.

A hypersonic missile taking flight from somewhere around the globe, soaring and maneuvering through the atmosphere faster than five times the speed of sound. At that speed, a threat would be very hard to stop.
That is the scenario that concerns U.S. officials. The concern is real. Russia and China both claim to have tested hypersonic systems.
“In the last year, China has tested more hypersonics weapons than we have in a decade,” Michael Griffin, the Pentagon’s top weapons researcher, said at a
National Defense Industrial Association-sponsored event in December. “We’ve got to fix that. Hypersonics is a game-changer.”
The U.S. Department of Defense is working on that fix. It has contracted with Raytheon and others to produce and rapidly deploy
hypersonic flight programs. That includes development of technologies to defeat hypersonic vehicles.
As the world celebrates the 50th anniversary of the Apollo 11 moonshot, Raytheon is pursuing a number of futuristic "moonshot" technologies that could represent the next giant leap, including counter-hypersonics and hypersonic vehicles.
In March, the DoD granted Raytheon a
$63 million contract to further develop the Tactical Boost Glide hypersonic flight program, a joint effort between the U.S. Defense Advanced Research Projects Agency and the U.S. Air Force.
For a tactical-range boost glide weapon to achieve hypersonic speeds, "a rocket accelerates its payload to high speeds. The payload then separates from the rocket and glides unpowered to its destination," according to the DARPA website.
Raytheon is also helping to develop air-breathing hypersonic systems. With engines built on a technology called a scramjet, the system uses a booster to reach cruising speeds. The missiles fly at sustained speeds above Mach 5 at certain altitudes in order to ensure the scramjet engine functions optimally.
The company has experience in the technical challenges of very high speeds, as it already produces missiles that travel above Mach 5.

MAKING THE MATERIALS
Vehicles require unique materials to fly so fast. They must withstand blazing temperatures from the friction produced as they accelerate through the atmosphere. That calls for advanced manufacturing.
Hypersonics must also be aerodynamically maneuverable, posing challenges related to thermodynamics, complex geometries, materials and manufacturing. The most effective shapes for hypersonic systems are highly complex and quite different from conventional aircraft or missiles. Those shapes are being developed for the first time.
Raytheon has made significant investments in advanced design manufacturing facilities, including its
Immersive Design Center, a virtual, 3-D environment for collaborative engineering and design.
The company
expanded its facilities in Tucson, Arizona, last year, dedicating an entire building to high-power computing, harnessed for its work on hypersonic systems.
“In order to develop these highly advanced systems, you need the appropriate infrastructure in place and the technical talent to solve the most challenging problems,” said Dr. Thomas Bussing, Raytheon Advanced Missile Systems vice president.

We have seen the future, and it is rife with increasing threats.
They are global in nature - unpredictable - coming from all distances, altitudes and speeds. This means that no nation, or system, can go at it alone. Effective missile defense requires partnership between industry and governments around the world to ensure a layered approach.
The 2019 U.S.
Missile Defense Review presented a strategy for layered missile defense, a time-tested concept that encompasses all domains, from sea to space. Combined with a collaborative approach among cooperating nations, a multi-tiered defense can help protect Europe and other regions.
An array of complementary technologies create the necessary layers of defense. Serving the U.S., its friends and allies, Raytheon is fielding and developing missile defense systems like Patriot and introducing new advancements in counter-hypersonics and advanced early warning capability.
"The world is getting to a point where it’s not (just) ballistic missiles across the globe as the prime threat, or tactical short range missiles. There are mid-range, hypersonics, all these threats that drive a need for a space-sensing layer in the international community," said Wallis Laughrey, Raytheon's vice president of Space Systems.
STAYING AHEAD OF THE OTHER GUY
The need for space-based early warning and tracking could be met by technologies such as the
Next Generation Overhead Persistent Infrared, or Next-Gen OPIR, Block 0 resilient missile warning satellite. The U.S. Air Force has budgeted $1.7 billion to develop a constellation of Next-Gen OPIR satellites, according to
Space News. Raytheon is one of two contractors chosen to develop the payload for these satellites.
Advanced sensors on satellites and other platforms make practical the U.S. Navy's ability to “launch on remote” or “engage on remote," allowing a naval commander to launch interceptors even before the ship's radar has pinned down the target. Distributed sensors, issuing a stream of data, allow for a "sensor-to-shooter" scenario, giving defenders the ability to act quickly on information from distant or nearby sensors.
“The shooter doesn’t need any other data other than what it gets from the radar to launch and engage and destroy that target," said Bryan Rosselli, vice president of Mission Systems and Sensors.
FILLING THE QUIVER
With adversaries racing to develop hypersonics, it's no wonder that faster-than-Mach 5 technologies are a dominant theme in the global conversation surrounding missile defense. Raytheon is working on several fronts to meet the technical challenges of operating at such high speeds.
Still, effective defense requires a full quiver of options; non-kinetic effects, cyber defenses and speed-of-light tech such as
directed energy. And ultimately, advanced command and control, or C2, to manage the full suite of defenses.
“Future missile defense is much more than hypersonics,” said Mitch Stevison, Raytheon Strategic and Naval Systems vice president.
Stevison advocates for a new way to think about C2 that is a “leap ahead,” where C2 is decentralized, as opposed to having specific C2 physical nodes that could become targets.
“There must be interfaces to the system, where the combatant commanders have the ability to operate the system, but there is no centralized C2 node," he said. "Everything is a C2 node, whether it is an effector, a radar on the ground or a satellite with a space-based sensor on it. They all have the ability to operate as part of a network or to operate autonomously."
