    You mean to say that during Soviet era, a static burnout of 500 seconds have been achieved? And still countries like US and China are struggling with 20 sec burnout?
    I would not even count India, who had achieved the burnout with a 1:16 scale model.

    As discussed before, this is a good move actually for obvious reasons. Similarly, not commenting on the number of nuclear warheads and letting others think that pakistan has more nuclear warheads is also a good move.

    Every defense enthusiast country does it. USA for example conveniently allowed the alien theory to grow in order to protect its secret fighter aircraft / NASA spaceships tests.

    Five bidders to contest USAF hypersonic weapon deal

    The US Air Force has narrowed its search for a new hypersonic strike weapon for bombers and fighters to five vendors.

    The service intends to award an engineering, manufacturing and development contract in early fiscal year 2018 to either Boeing, Lockheed Martin, Northrop Grumman, Orbital ATK or Raytheon. Only those companies could produce the weapon within the USAF’s timeframe, according to a 21 July notice of contract action on the US Federal Business Opportunities website.

    Dubbed the hypersonic conventional strike weapon, the selected design will provide a precision strike capability against fixed and moving targets in an anti-access, area-denial environment using Global Positioning System and Inertial Guidance System navigation, the notice states. It will be fielded on an unnamed, government-issued warhead flying on existing fighter jets and bombers, it adds.

    A subsequent, 29 June notice emphasises rapid fielding, and seeks vendors skilled in hypersonic aerodynamics, aero-thermal protection systems, solid rocket motors, missile integration, advanced hypersonic guidance, navigation and control, and aircraft integration. It also outlines the need for a strike weapon powered by solid rocket motors, leaving out the possibility of an air-breathing supersonic combustion ramjet-propelled design.

    Last year, the USAF qualified a new explosive formulation for extremely high temperatures, which would apply to hypersonic weapons, according to FY2018 budget justification documents released by the service outlining research and development of conventional munitions.

    The USAF has an existing inventory of ground-launched hypersonic weapons which can fly at five times the speed of sound, but has no air-launched weapons that can exceed Mach 5.

    Bomb is huge Bhai. Although technically it makes perfect sense by looking at payload range trade-off. Still what is the source since govt even downplays A5 range.

    ‘Developing hypersonic vehicle, we are nearly there’

    Director of DRDL M.S.R. Prasad addresses a workshop at IIT-Hyderabad

    Hypersonic space and missile technologies were still a distant dream, despite serious efforts being made across the world, said M.S.R. Prasad, Director of Defence Research and Development Laboratory (DRDL).

    “Supersonic aero dynamics is an interesting subject. Commendable work is being done in different parts of the country. It appears we are nearly there, but there are a lot of issues to be addressed.

    In the next 10 years, we will see vehicles flying at supersonic speed,” said Mr. Prasad, while addressing a large number of students, defence experts and others at a workshop on ‘Challenges in Air-breathing Hypersonic Technologies’ held at the Indian Institute of Technology, Hyderabad (IITH) in association with the Aeronautical Society of India (AeSI) on its campus on Saturday. “Speed is what humans always need. Hypersonic is on the mind of everyone and would certainly take off. We have seen some work being done in the area and in one of the experiments by Vikram Sarabhai Space Centre (VSSC), scramjet engine was tested for 20 seconds in captive mode to understand certain aspects,” he said.

    He said research work could be taken up by the students as there were several challenges that were involved in achieving the target in hypersonic technology. He said temperature was one of the critical aspects that needed to be addressed while designing an hypersonic vehicle as high temperature of up to 1800 C would be generated when these vehicles travel.

    He said developing temperature-resistant material was a challenge too in addition to thermal coating and said that he hoped the workshop would be able to identify the issues to be addressed in the area.

    Samir V. Kamat, DS and DG (NSM), DRDO, said several materials have been tried over the years starting from early 80s when the U.S. launched a major national aero space programme that was meant to carry passengers in a hypersonic flight. “Unfortunately, till now, no deliverable or usable hypersonic vehicle has been made. But I am sure it will happen in the next 10 years at least for military purposes,” he said.

    N. Shyam Mohan, Project Director, RLV-TD, VSSC, Thiruvananthapuram, R.K. Sharma, Project Director, HSTDV, DRDL, and others also spoke.

    DRDO Electromagnetic Railgun :- The Future Weapon Of Indian Navy

    [​IMG]



    Rail gun is a weapon capable of launching projectile without the usage of explosives or propellants, but, are launched at extremely high velocities, mach 7 (at sea level) or more. Capability of launching projectiles at velocities higher than guns and cannons makes rail gun hit targets at greater ranges capable of hitting the target with extreme speed and accuracy thus nullifying the escape factor of the enemy platform or an approaching projectile. With the usage of rail gun the hazards of usage of explosives and chemical propellants are evaded as well.

    Ever since the U.S. NAVY showed the power of the Railgun and its advantages,we in the Indian Defense Research organization feel that this latest weapon the electromagnetic railgun launcher will give our Naval forces in the Arabian sea a superlative advantage and a capability to launch devastating attacks on both land and sea targets.

    This gun uses a form of electromagnetic energy known as the Lorentz force to hurl a 230-250 pound projectile at speeds exceeding Mach 7-8.
    According to the DRDO website, a 12 mm square bore Electromagnetic Railgun (EMRG) has actually been tested. Another 30 mm square bore EMRG is also ready for tests.Their target is to accelerate a 1 kg projectile to a velocity of more than 2000 m/s (~Mach 6) with a capacitor bank of 10 Mega Joules.

    As of now it is in a rudimentary prototype stage and further tests are required to improve it’s performance and make it a feasible weapon system.
    The electromagnetic railgun represents an incredible new blistering offensive capability for our Navy which rules the Arabian sea right now. This capability will allow us to effectively counter a wide range of threats at a relatively low cost, while keeping our ships and sailors safer by removing the need to carry many high-explosive weapons on the ship.

    This massive railgun that we are developing needs just one navy-gunner/sailor to operate and it relies on the electromagnetic energy of the Lorentz force—the combination of electric and magnetic forces on a point charge—for power.

    The problem is that the only ships that will be able to generate the gargantuan 25 megawatts of power (enough to power almost 19,000 homes) required to fire the railgun are the aircraft Carrier and Destroyers

    The issue of power is a barrier that will get smaller with time. New capacitors, more resistant materials and better pulse power storage systems could all contribute to making the railgun more efficient. Computer-aided design, 3D printing techniques and better dielectric materials—materials that don’t conduct electricity but can store energy in the form of an electrostatic field—could all lead to making the EM railgun viable.

    The Indian Navy likes this weapon for several reasons, not the least of which it has a range of 200 miles and doesn’t require explosive warheads. That makes it far safer for sailors, and cheaper for taxpayers. According to the Indian Army and Navy experts each 12-inch diameter tapered projectile which is 6 feet in Length and 250 pounds costs about Rs 15,00,000, compared to Rs 7500,000 for conventional missiles.
    Also since the missiles are hurled at the speed of mach 7-8. they will hit their targets within seconds after being fired with explosive force.

    Testing OF Rail Gun:

    On 31st January 2008 U.S. Navy tested a rail gun that fired a projectile at 10.64 MJ with a muzzle velocity of 2,520 m/s. The required power was provided by a new 9-megajoule capacitor bank using solid-state switches and high-energy-density capacitors and an older 32-megajoule pulse power system from the US Army’s Green Farm Electric Gun Research and Development Facility. The rail gun is expected to be ready for deployment between 2020 to 2025.

    With the advent of rail gun as a weapon owing to its ultra high speed and accuracy which will allow for a abysmally small reaction time to evade its projectile, all airborne battle platforms like fighter jets and sea faring battle platforms like aircraft carriers and large ships will theoritically become outdated and will run the risk of unavoidable destruction once detected and targeted by the radar of the launching ship or platform harbouring the rail gun. Guided rail gun projectiles are also being thought of to be developed.

    It seems that future warfare attack as well as defence systems will have to depend on radars and launch platforms having the ability to respond within extremely small scope of reaction time and having the capability to launch hypersonic projectiles/missiles and ultra high energy DEW within that time to counter launches from platforms such as the rail gun. With such lethal launching platforms of weapon the launching platform which will detect and launch an attack first will hold a great advantage over its adversary.

    Navy Conducts Flight Test to Support Conventional Prompt Strike From Ohio-Class SSGNs

    [​IMG]

    The Navy Strategic Systems Program and the Department of Defense this week tested a conventional prompt strike capability that could one day be fielded from guided-missile submarines.

    The Pentagon’s conventional prompt global strike capability would allow the U.S. to hit any target on the planet with precision-guided weapons in less than an hour, supplementing the comparable nuclear strike capability and serving as another deterrence effort.

    Strategic Systems Program (SSP) Director Vice Adm. Terry Benedict said on Nov. 2 that “I’m very proud to report that at 0300 on Monday night SSP flew from Hawaii [Pacific Missile Range Facility] … the first conventional prompt strike missile for the United States Navy in the form factor that would eventually, could eventually be utilized if leadership chooses to do so in an Ohio-class tube. It’s a monumental achievement.”

    The admiral spoke at the Naval Submarine League’s annual symposium in Arlington, Va. He credited his organization for, in addition to working on the nuclear weapons that support the Ohio-class boomers and their Columbia-class replacement in development now, “we have supported the OSD AT&L defense-wide account for technology demonstration, and on our first go out of the box a very successful flight of a conventional prompt strike maneuvering reentry body.”

    Four Ohio-class SSBNs were previously converted to guided-missile submarines (SSGNs) to carry conventional weapons. These four subs — or future Virginia-class attack submarines with the Virginia Payload Module that inserts additional missile tube capacity into the smaller boat — would likely be the ones contributing to conventional prompt global strike, if Pentagon leadership were to pursue the idea being tested now, the Strategic Systems Program office told USNI News.

    When asked about the test during a question and answer session, Benedict said he could not comment further and had to refer all questions to the Office of the Under Secretary of Defense for Acquisition, Technology, and Logistics (OUSD(AT&L)), which manages the conventional prompt strike capability.

    Pentagon spokesman Cmdr. Patrick Evans told USNI News today that “the Navy Strategic Systems Program (SSP), on behalf of the Department of Defense, conducted an Intermediate Range Conventional Prompt Strike Flight Experiment-1 (CPS FE-1) test on Oct. 30, 2017, from Pacific Missile Range Facility, Kauai,waii. The test collected data on hypersonic boost-glide technologies and test-range performance for long-range atmospheric flight. This data will be used by the Department of Defense to anchor ground testing, modeling, and simulation of hypersonic flight vehicle performance and is applicable to a range of possible Conventional Prompt Strike (CPS) concepts.”

    In addition to Navy and AT&L assets, the Missile Defense Agency participated in tracking and data collection activities, he added.

    Evans added that AT&L “is investigating technologies and concepts that are potentially useful for developing intermediate-range conventional capabilities through modeling and simulation, ground tests, and flight test experiments. OUSD(AT&L) uses a national team, comprised of Navy, Army, Air Force, national research laboratories, and university affiliated research centers, to pursue technology development objectives. The Navy was assigned to lead the Flight Experiment 1 (FE-1).”
