Q1. What are Hypersonic Weapons? Highlight their significance and discuss the challenges in their adoption and use.(150 words) 10 marks

Model Structure

  • Hypersonic Weapons are those that can travel at 5 times the speed of sound, or faster, in the air (greater than 5000 km per hour).
  • Hypersonic cruise missiles use high-speed, air-breathing scramjet engines to push them to hypersonic speeds, while hypersonic glide missiles are launched from a rocket from space and glides to a target at an unpredictable trajectory.

Main Body:

  • Significance of Hypersonic technology:
    • Faster and long-range cruise missiles: A hypersonic cruise missile, flying faster than any fighter, would strike its target well before it can be intercepted.
    • Undetectability: These missiles can fly lower than the traditional ballistic missiles, thus, they tend to avoid radar detection.
    • Quick reaction missile: Hypersonic Missile is a “quick reaction missile" which can be used to intercept incoming missiles in the outer atmosphere or in the inner atmosphere.
    • Maneuverability: Hypersonic weapons travel within the atmosphere and can maneuver midway which combined with their high speeds, which makes their detection and interception extremely difficult.
    • Role in other areas: This technology will also allow India to launch satellites into space at a significantly reduced cost, and is fundamental to India's drive towards the development and deployment of reusable rockets.
    • Boost to India missile defense capabilities: development of a range of cruise and ballistic missiles including Prithvi and Agni missiles, anti-tank Nag, and surface-to-air Akash under the Integrated Guided Missile Development Programme.
  • Challenges in their adoption and use:
    • At such high speeds, handling extreme heat produced, as well as accurately positioning and maneuvering missiles.
    • Both Hypersonic Cruise Missiles (HCM) and Hypersonic Glide Vehicles (HGV) involve esoteric technologies.
      • Operationalising them would also require ‘intelligence, surveillance, target acquisition, and reconnaissance’ (ISTAR) assets.
    • Hypersonic weapons fly at a low altitude only, for instance, HGVs do not rise above 100-110 km altitude and HCMs fly even lower, at about 20-30 km altitude.
    • Principles for when to use Hypersonic Weapons have not been set and the ramifications of using them have not been thought through, thereby raising tough questions about their efficacy.
    • Increases the ongoing modernization of nuclear weapons in a competitive global environment.
      • For example, China and Russia are developing hypersonic glide vehicles, and Russia is probably developing a nuclear-armed, nuclear powered underwater vehicle.


  • India has developed a surface to surface tactical missile codenamed Shaurya, which has a hypersonic speed of 7.5 Mach. Also, BrahMos 2 is under joint development by India and Russia.

Q2. What do you mean by Metaverse? Discuss the impact it is going to have on everyday’s life ? (150 words) 10 marks

Model structure

  • The metaverse is a virtual-reality space in which users can interact with a computer-generated 3D environment and with each other.
  • People can create their own avatar or character that represents them, place that avatar in a virtual space, manipulate them with hardware like virtual reality tools and effectively live a life in this environment.

Main Body

  • Positive Impact of Metaverse:
    • Changed gaming and entertainment experience: Players can not only play games but use it for other activities as well.
      • For example, in the multiplayer game Fortnite, 12.3 million players took part in a virtual in-game music tour.
    • New forms of social and commercial interactions: Extended reality and blockchain will produce applications that increasingly blend our physical and digital identities.
    • Digital economy: where users can create, buy or sell goods.
      • In an advanced and interoperable version of metaverse, people can take virtual items like clothes or cars from one platform to another.
    • Ownership: Cryptocurrencies and NFTs (Non-Fungible Tokens) could enable the ownership of virtual items and real estate within the metaverse.
    • Defense: connecting virtual environments for acquisitions with those used for experimentation or training.
      • Allowing quick test or assessment of designs in a future operating environment-like virtual world.
    • Industrial Revolution 4.0: revolutionize customer expectations, product improvement, and collaborative innovation, thus giving a fillip to industrial revolution 4.0.
    • New job profiles: Metaverse will further create and augment new job profiles such as AR/VR software engineers, 3D game designers, hardware engineers, Metaverse marketing specialists etc.
  • Negative impact of Metaverse:
    • Cyber-attacks: Infrastructure required for the new environment is exponentially more extensive and with every such endpoint there is possibility to take over identities on the network or block access through denial-of-service attacks or to pull data from virtual meetings and presentations.
    • Threat to privacy: Metaverse platforms would be able to collect images and other personal details of their users, which would threaten the privacy of users.
    • Misdirection of avatars: Attackers could manipulate a virtual reality platform to reset the physical boundaries of hardware.
      • With augmented reality a user could be misdirected into a dangerous physical situation, such as a robbery or sexual harassment of other avatars.
    • Mental health related issues could arise due to long-term immersion in the virtual world.
      • For example, users might experience “phantom timeline syndrome”, where the lines between the virtual world and physical world become blurred.
  • Way forward:
    • Digital literacy: Digital literacy, safety and wellbeing of users should be promoted so that users can consciously navigate harmful content and behaviors.
    • Meta-governance: Steps should be taken to make the metaverse as open and interoperable as possible and should not be controlled by big tech companies only.
    • Policies and laws: Policies and laws should be in place to ensure that the metaverse is not used for unethical purposes such as sexual harassment of women and children etc.


  • Thus, the metaverse opens up a new world of opportunities but at the same time it also brings challenges for society. Steps should be taken so that the new virtual world remains inclusive.
