Is the Future Defense Technology Disruption Led by Hypersonic Systems?

As per defense reports, German researchers created rocket engines during World War II. The propellant, a mixture of fuel and chemical oxidizer, is burned in a rocket engine to produce a powerful burst of energy. Following that, defense reports suggest that the experimental rocket-powered aircraft shattered record after record for speed. The rocket-powered X-1 crossed Mach 1 in October 1947, becoming the first piloted aircraft to do so, while the X-15 achieved Mach 6.7 in tests in the 1960s. Piloted rocket-propelled aircraft were never more than experiments due to the enormous demands that high g-forces had on human physiology. However, the Soviet Union and the United States were able to develop nuclear-capable ballistic missile arsenals that could travel across continents thanks to rocket technology.

Unlike ballistic missiles, which have fixed trajectories and limited agility hypersonic missiles can reach hypersonic speeds of Mach 5 and beyond as per defense reports. Hypersonic glide vehicles and hypersonic cruise missiles are the two main subcategories of hypersonic weapons. Rocket propulsion is used to launch hypersonic glide vehicles, then the glide vehicle separates from the rocket and “glides” at a minimum of Mach 5 speeds towards the target. High-speed, air-breathing engines are used to power hypersonic cruise missiles.

Any nation that has the ability to launch highly agile missiles at hypersonic speeds has a significant advantage because such weapons can bypass almost any current defense system. China, Russia, and the United States are all working on building hypersonic weapons. While some nations have made unsubstantiated claims of testing these weapons, more nations are researching weapons.


Under the Navy’s Conventional Prompt Strike programme, which aims to give the U.S. military the ability to strike hardened or time-sensitive targets with conventional warheads, as well as through a number of Air Force, Army, and DARPA programmes, the Department of Defense (DOD) is currently developing these weapons as per defense reports. Supporters of these programmes contend that hypersonic weapons could improve deterrence and give the American military the ability to overcome systems like modern air and missile defense systems, which serve as the cornerstone of American opponents’ anti-access/area denial measures. Hypersonic weapons are one of the main technologies that will be able to fight and win the battles of the future, according to the 2018 National Defense Strategy. The bipartisan Future of Defense Task Force Report from the House Armed Services Committee also mentions that the United States may face difficulties as a result of these weapons in the future. The U.S. programme for hypersonic weapons calls for conventional armament, in contrast to those of China and Russia. Because of this, American hypersonic weapons will probably need to be more precise and technically difficult to create than nuclear-armed Chinese and Russian systems according to defense reports.


The Avangard and the 3M22 Tsirkon (or Zircon) are two of these weapons programmes that Russia is developing, while the Kinzhal (“Dagger”), a maneuverable air-launched ballistic missile, is also apparently in service. An intercontinental ballistic missile (ICBM) is used to launch the hypersonic glide vehicle, Avangard, giving it essentially infinite range. Avangard is now mounted on the SS-19 Stiletto ICBM; however, Russia intends to launch the vehicle eventually from the Sarmat ICBM. Despite being successfully tested in April 2022 and expected to be deployed by the end of the year, Sarmat is still in development. Hypersonic Glide vehicle, Avangard is believed to have built-in defenses and will be equipped with a nuclear warhead. A modified version of the Iskander hypersonic missile, the Kinzhal is a manoeuvring air-launched ballistic missile that Russia has deployed. Russia fired the Kinzhal missile in Ukraine from an MIG-31 interceptor plane and also has plans to mount the missile on the Su-34 long-range attack fighter and the Tu-22M3 strategic bomber.


At least one missile with the ability to transport hypersonic glide vehicles may already be in operation, and China is actively developing hypersonic cruise missiles and hypersonic glide vehicles. Over a year after firing its first hypersonic missile in July 2021, China has made shocking claims about testing reliable communications during several hypersonic flight tests according to defense reports.


Defense intelligence states that AUKUS, an alliance of Australia, the United Kingdom, and the United States, has decided to work together on developing hypersonic and electronic warfare capabilities. The three AUKUS security alliance members’ initiative comes as worries about China’s military aggression in the Pacific are intensifying. The Pentagon has already requested $4.7 billion for research and development of these weapons in its budget request for 2023. A hypersonic missile battery would be deployed by the next year, a sea-based missile by 2025, and an air-based cruise missile by 2027 as per Defense intelligence.


Within the next five to six years as per Defense intelligence, India is anticipated to develop its own hypersonic missile. The fastest supersonic cruise missile, the BrahMos, was created by a joint venture between India and Russia in the aerospace and defense industries. Along with BrahMos Aerospace, the Defense Research and Development Organization (DRDO) is working on a number of projects, including BrahMos 2. The Hypersonic Technology Demonstration Vehicle, or HSTDV, was successfully tested by the DRDO in 2020, reaching speeds of Mach 6 according to Defense intelligence.


Establishing stable communication link with the hypersonic weapon still continue to be a challenge. The communication blackout is brought on by the plasma sheath, a thin layer of incredibly hot, electrically charged particles that emerge on the surface of the vessel at hypersonic speed. The “black barrier” refers to the difficulty in locating and locking on to a hypersonic target using ground-based radar as per Defense intelligence. It is difficult to observe and predict how these particles, which reflect, absorb, and distort radio waves, would behave under turbulence.

Aerodynamic parameter uncertainty necessitates the use of resilient techniques in the design of the control system as per Defense intelligence. To keep the desired vehicle flight performance, adaptive control techniques can be necessary. The drag and lift forces become nonlinear functions of the angle of attack at hypersonic speeds. The maximum lift/drag ratio for hypersonic vehicles is much lower than for subsonic and supersonic speeds. Heating compromises the structural integrity of the vehicle and, depending on the airframe, may result in structural vibration, which must be taken into account while designing the control system.
