In today’s tech-savvy world, where one side other countries are picking up speed in arms race, as another side united state don’t want to left behind. So, US air force gives two contracts of superfast weapon systems- named Air-Launched Rapid Response Weapon (ARRW) and Hypersonic Coventional Strike Weapon(HCSW) to Lockheed Martin. In April, for developing Hypersonic Conventional Strike Weapon (HCSW), first contract is given worth up to $928milion. Last week, the air force disclosed another deal to develop the Air-Launched Rapid Response Weapon (ARRW), awards $480 million. A few years ago, long duration flight was just a dream for an air force, but now US air force makes this dream reality by DARPA’s Falcon Hypersonic Technology Vehicle 2 (HTV-2) program- multiplayer research and development efforts. Being an experimental hypersonic glide vehicle rocket glider, hypersonic technology can fly at 13,000 mph speeds. Last week in a statement, Heather Wilson, secretary of air force said,” “We are going to go fast and leverage the best technology available to get the hypersonic capability to the warfighter as soon as possible”. The hypersonic vehicle uses a rocket engine, supersonic combustion Ramjet, and another jet engine. It has the capability to run at least 4 times faster than the sound speed. In the hypersonic technology field, ARRW and HCSW are not the first assault of the US military. As shown that, several test flights of an unmanned hypersonic bomber prototype-HTV-2 has been launched by the defense advanced research project agency(DARPA). On August 2011, a vehicle has reached Mach 20 speed before losing control during one of the trials of flight tests. Hypersonic technology can be missiles, planes and other vehicles but in this article, we will tell you about hypersonic weapons plans. These two superfast weapons are not first frayors of US air force, the big example of this statement that, from 2004 to 2013, air force and DARPA developed and tested a Waverider which is a robotic scramjet vehicle by working together from 2004 to 2013. Also, military officers have said, ” Waverider technology can be found a way into a hypersonic weapon”. On 28 June, air force, navy, army, and missile defense agency signed a contract to work together on the development of “hypersonic boost-glide technology.” David golden fish- air force chief of staff Gen. Said in the statement,” “The Joint Team requires the right mix of agile capabilities to compete, deter and win across the spectrum of competition and conflict.” Nowadays, as the world is becoming more powerful, as soon as superfast weapon state is becoming a big competition between the most countries. Recently, in a conference, Russian officials have declared that they will be developing a jet-launched hypersonic vehicle by 2020. And also, earlier this month, China tested Xingkong-2 which is hypersonic wave rider. And this test was successful, according to Chinese media report,” this weapon flew approximately Mach 4 and under 400 sec it reached Mach 6.
