I :mod: warn the DRDO now test fire Nirbhay , no more excuses no more time. Feb over also over Aug and now Sep is over. u cant live Nirbhay without test of nirbhay. scientists are the busy with 20 20 match..........?
 
The first Nirbhay LACM could be air-launched from Su-30MKI.

What ??? Are you saying that the first ever test of Nirbhay will be from MKI .

LACM = Land-Attack Cruise Missiles

ALCM = Air-Launched Cruise Missile

Now you have to wait till Dec this year for the test or another postponement message :sick:

You don't get it. Any cruise missile designed to attack land targets are called LACMs. Ground-launched
ones are called GLCM. Prasun Sengupta claimed that the first Nirbhay test will be air-launched, land-attack.
 
India tests Prithvi missile's naval version Dhanush

Balasore: India successfully test-fired nuclear capable Dhanush, the naval version of Prithvi short-range ballistic missile, from a warship off Odisha coast on Friday. The indigenously developed naval version of the Prithvi short-range ballistic missile has a strike range of up to 350 km and can carry 500 kg of conventional or nuclear warhead, a DRDO official said.

"Dhanush was test-fired from a naval ship off Odisha coast at around 1125 hours," Ravi Kumar Gupta, Director in the Directorate of Public Interface in Defence Research and Development Organisation (DRDO) told PTI over phone.

Describing the trial as fully successful, Gupta said the test was conducted by the strategic force command (SFC) of the Indian Navy. "The trial was a complete success and all the mission objectives were accomplished," he said.
 

the gist of his findings

Nuclear-Capable Agni-1 Ballistic Missile's Range Can Be Extended To 1500 Km....
...with the help of advanced, light-weight composite materials for the construction of its body & lighter warhead designs.

This was one of the findings of an analysis carried out of the Agni-1 Ballistic Missile, that has been deployed under the operational command of the country's SFC, using open-source data. One 'vivek_ahuja', a well-regarded members of the Bharat Rakshak Forum, has authored this paper. A look up on the Internet for his name threw some information about his credentials. Credible.

Star-Grain-Solid-Rocket-Fuel
For the completion of its mission, the missile has been calculated to be carrying 8510 Kg of Solid Rocket Fuel - HTPB. It is stored in what is described as a 'star grain' configuration [Photograph on left]. It basically refers to the manner in which the solid fuel is arranged or shaped inside the missile. One significant advantage of using liquid rocket fuels is that the characteristic nature of combustion,
Solid-Rocket-Propellant-Grain-Regression
at any given time, can be dynamically varied, if required, by controlling the flow of fuel and oxidisers into the combustion chamber with the help of control valves. Solid rocket fuel combustion can not be similarly controlled. Once ignited, the solid fuel will continue to burn till all of it has been consumed. A method that enables a degree of control over its combustion characteristics is the fuel stacking arrangement, or grain of the propellant. This '6-pointed Star Grain' configuration, he concludes, can provide the Agni-I with an effective combustion [and corresponding thrust] characteristics, both inside the atmosphere [low velocity, therefore less drag losses], as well as when almost out of it [higher acceleration]. The diagram to the right gives an idea of how solid rocket fuel gets consumed in flight. The missile has been estimated to take 9 minutes to reach its target, with the powered flight [stage where fuel burns] lasting for around 40 seconds & the missile warhead attaining velocity of Mach 7 prior to its impact on target.

Being the outcome of a development programme initiated earlier, the missile has an all-metal body construction, built using
Agni-1-Missile-1000-kg-warhead-Composite-casing-01
Maraging Steel. Since that time, with the Agni-IV project, DRDO has demonstrated successfully its ability to utilise high strength but light weight composites to build casings. Therefore, it would be logical to assume that this manufacturing technology would also find application in the building of future Agni-1s. Use of composites would enable its users to lob the missile, with its existing warhead, even farther, up to a distance of 1250 Km, claims the author.

The range of Agni 1 missile has been estimated assuming a warhead mass of 1000 Kg. It corresponds to BARC's untested 200 Kt boosted fission warhead design, with the Agni-1's Re-Entry Vehicle [RV] designed accordingly. Carrying a warhead weighing lesser would, therefore, enable it to reach targets further down-range. Calculations suggest a distance of 1500 km can, theoretically, be reached if the missile were to be made of composites & carrying a lesser [unspecified]
Agni-1-Missile-1000-kg-warhead-Metal-casing-01
mass of payload. However, it seems unlikely that, in the current scenario there would be any major re-design on that front. That is because, following Operation Shakti, India declared a self-imposed moratorium on further tests. Thus, any new design will, therefore, also remain untested, unless it decides to take a break from the moratorium. An unlikely proposition. A 1000 Kg mass would provide you with the leeway to over-engineer the design, thus making up for not testing it. It is also being debated whether the data generated from just 5+1 tests are enough to create models for simulations that can help design newer warheads without physically testing them with sufficient reliability+. Therefore, a conservative conclusion would state that there will be no major changes in the Agni-1's warhead design, and will continue to weigh in the range of 1000 kg. Thus, going by this assumption, one can conclude that the missile's range can be practically extended to 1250 km. There have been speculations, that one of the clauses during the signing of the upwards of $12 billion USD contract with France for the acquisition of around 126 MMRCA includes access to its Inertial Confinement Fusion facility near Bordeaux. There, however, has been no further "leaks" elaborating this proposal.

Nuclear-Capable Agni-1 Ballistic Missile's Range Can Be Extended To 1500 Km.... - AA Me, IN
 

There have been speculations, that one of the clauses during the signing of the upwards of $12 billion USD contract with France for the acquisition of around 126 MMRCA includes access to its Inertial Confinement Fusion facility near Bordeaux. There, however, has been no further "leaks" elaborating this proposal.

This has been speculated by a number of people. Hope this is not just a far fetched idea.

A big deal | Deccan Chronicle
Rafale seems to have an edge, owing to its Active Electronically Scanned Array radar for air-to-air missions, whereas EADS has it only as prototype. This is fortuitous in a way because France can, as an inalienable part of the MMRCA deal, be persuaded to allow Indian nuclear weapon designers access to its Megajoule inertial confinement nuclear fusion facility near Bordeaux, to help rectify the thermonuclear weapon design that proved a dud on testing in 1998, and to work on other fusion weapon configurations. This will not obviate the need for tests in future, but inspire some confidence in the Indian strategic nuclear arsenal in the interim. Such access is a must and it can be extracted, howsoever painfully, from Paris now when it is desperate to keep a aircraft design and development capability alive in France. It is an opportunity not to be missed.
