They are launched on rockets and then orbit the earth at their own speed. They are difficult to track because, unlike ballistic missiles, they \u201cdo not follow the fixed parabolic trajectory\u201d.<\/p>\n<p><strong>Note:\u00a0<\/strong>Countries like the US, Russia and China are developing hypersonic glide vehicles.<\/p>\n<h5>About India and hypersonic technology<\/h5>\n<p>India too is working on hypersonic technologies.

It is launched at more than five times to 25 times the speed of sound.<\/p>\n<p>The vehicle is capable of carrying nuclear payloads, which gives the launching country the strategic capacity to attack almost any target across the world.<\/p>\n<h5>Difference between Hypersonic Glide Vehicle and ICBM<\/h5>\n<p>ICBM follows a parabolic trajectory, which means it goes up and then comes down in a high arc\u2014like throwing up a ball.<\/p>\n<p>On the other hand,\u00a0 hypersonic glide vehicles orbit the earth at a lower height and are manoeuvrable. The ability to change track or target, mid-trajectory, along with the speed, makes them tougher to track and defend against.<\/p>\n<p>Moreover, hypersonic missiles can travel approximately 5,000 to 25,000 km per hour, which makes them six to over 25 times faster than modern commercial aircraft.<\/p>\n<p>Hence, the mix of the high altitude, high speed and manoeuvrability of hypersonic missiles can potentially provide them to use in-flight updates to attack a different target than originally planned.<\/p>\n<hr \/>\n<h3 style=\"text-align: center;\"><span style=\"color: #0000ff;\">Long Range Bomb<\/span><\/h3>\n<h5>News<\/h5>\n<p>Defence Research and Development Organisation(DRDO) and Indian Air Force (IAF) have jointly flight-tested Long-Range Bomb(LRB).<\/p>\n<h5>About the Long Range Bomb(LRB)<\/h5>\n<p>Long Range Bomb is\u00a0<strong>India\u2019s first indigenously-developed guided bomb<\/strong>.It will be used to attack land-based targets at a long-range with greater accuracy.<\/p>\n<p><strong>Developed by:\u00a0<\/strong>It has been designed and developed by Research Centre Imarat (RCI), a DRDO laboratory located at Hyderabad in coordination with other DRDO laboratories.<\/p>\n<p><strong>Range:<\/strong>\u00a0The bomb has\u00a0a range of around 100 kilometres.<\/p>\n<p><strong>Significance:<\/strong>\u00a0This development is important as India in the past has been using Israeli laser-guided bombs.
