unless current Astra achieve maturity.
What has left immature in Astra ?? If it was immature then why IAF cleared user trials ??Since 2017, despite of repeated news of production we are not able to see a single missile on Su-30mki or any of jet. Where are those 50 lsp ordered in 2017?
We only hear fake news and fake claims of immaturity and production issues while reality is emergency procurement already has taken place. IAF don't need it now because they have now ample store of BVR/WVR missiles.

Wish I had been CAS. I would have organized a fashion show of Astra with MKI, Mig29, Tejas just for you.

They are already organizing fashion show of MICA, Derby, Russian junk (as per IAF ) just to appease their masters but shy away by miles when it's come to Indian products.
How Astra is immature despite of clearing all due trials?

Calculating the loss to the exchequer due to poor quality OFB ammunition to be Rs 960 crore between 2014 and 2020, the Army notes, “Rs 960 crore roughly means 100 155-mm medium artillery guns could have been bought for this amount."
Timing of the report is interesting.

:facepalm:
Typical fanboy conception: the bigger, the better?
Comparing to heavy missile, the lighter weight has the benefits in storage, maintenance, response time, transport maneuver.
US, Russia, China and France, their latest ICBMs are all over 10000km with <60ton weight, only fools will expect a 100 tons missile which can only sit in the silo.
I don't have time for idiots whose english comprehension is zero and lack the brain to understand what is written.

There is no point wasting time explaining again , since except for you everybody got the joke .

Why so interested in making yourself look like a clown ?

Army should deliberately do such leaks in particular intervals to create pressure and to fast track the corporatisation of OFB.
Hypothetically what's stopping the Corporatization of OFB, other than the Workers Protest? are there some kind of legal ramification that we are not aware of.

I think a video presentation of this is already out there.
Secrecy is not in the description
Secrecy is in the implementation/application

Eg

Grenades is thrown at enemies ( description )

Grenade can if desired be used in a boobytrap ( application )
Grenade if desired can be used to fuze an IED ( application )

I hope you get the gist

Political headache, being called Ambani agent by opposition. Political parties can take advantage of this and can stage wide spread protest.

Employee will go supreme court and you know what kind of judges we have. Government may end up paying large compensations.

Being PSUs, its government duty to safeguard employees future. Steady Disinvestment will be a good idea rather than selling OFB overnight

saras mk2.
Looks beautiful. Radical departure from previous model of Saras. Though the previous iteration looked innovative I did not like the design.
Sometimes conventional old fashioned designs look and work better.
Wonder what make of turboprop engines it will use.

Archives Archives « Indigenous heavy artillery gun accident report in 10 days Money burnt on faulty ammo could have bought us 100 new Howitzers, fumes Army Published September 29, 2020 | By admin SOURCE: INIDA TODAY The Indian Army funds spent on dangerously faulty ammunition supplied by the state-owned Ordnance Factory Board (OFB) over the last six years would have been enough to purchase 100 medium artillery guns. This staggering claim has been made in an internal Army report to the Ministry of Defence (MoD), excerpts of which have been accessed by India Today. Calculating the loss to the exchequer due to poor quality OFB ammunition to be Rs 960 crore between 2014 and 2020, the Army notes, “Rs 960 crore roughly means 100 155-mm medium artillery guns could have been bought for this amount.” The OFB, administered by the MoD’s Department of Defence Production, is one of the world’s oldest government-controlled production organisations, and oversees a nationwide network of factories that manufactures ammunition and weaponry for the Indian armed forces. The ammunition being criticised in the new Army report includes 23-mm air defence shells, artillery shells, 125-mm tank rounds and different calibres of bullets used in infantry assault rifles. ‘POOR QUALITY’ AMMUNITION The Army report accessed by India Today highlights the ‘poor quality production’ at the OFB, quantifying the losses both in monetary resources as well as human life due to accidents caused by faulty ammunition. “Lack of accountability and poor quality of production results in frequent accidents. This results in injuries and deaths of soldiers. On an average, one accident takes place per week,” says the report that has been shared with the MoD, including accident and casualty figures. There have been 403 accidents related to faulty ammunition since 2014, though the numbers of accidents have steadily reduced. From 114 accidents in 2014, the number reduced to 53 by 2017, rose again to 78 in 2018, and dipped once again to just 16 in 2019. But the human casualty figures are far more disturbing. Listed under the heading ‘Casualties due to OFB manufactured ammunition and armament’, the report notes 27 troops and others have been killed in faulty ammunition accidents since 2014, with 159 being seriously injured, including permanent disabilities and loss of limbs. There have been 13 accidents so far in 2020, though none of them has resulted in a death. Calculating Rs 960 crore as the monetary write-off as a result of faulty OFB ammunition since 2014, the Army report notes that Rs 658.58 crore worth was disposed of within the ammunition’s shelf life between April 2014 and April 2019, while 303.23 crore worth of mines were disposed of within their shelf life following a major ammunition depot fire in Pulgaon, Maharashtra in 2016. ‘MINI-OFB’ TYPE SUPPLIERS NEEDED The Army’s exasperation with OFB supplied ammunition has simmered over decades, reaching a breaking point in the last two years, forcing an effort to approach the Indian private sector to meet ammunition needs. But as India Today reported earlier this month, the Army has pulled the plug on five of seven proposals that would have seen private firms step in to keep ammunition supplies running. However, the effort to get private companies to become ‘mini-OFB’ type suppliers is desperately needed. Earlier this month, the Army’s ‘ammunition-in-chief’, the Master General Ordnance (MGO) Lt Gen Upadhya said at an industry interaction, “OFB is in any case available to us. We want a parallel capacity to come up. It may not be at the scale of the OFB. But to start with, at least a parallel set up should come and various types of ammunition would then be available from the industry which can then settle down and in the times to come, a scaling up can take place.” The Army has a difficult situation on its hands, and one that needs to be navigated tactfully. On the one hand, pushback against the OFB goes directly against the MoD itself, even though the latter has begun a process of modernisation of the OFB. Just this month, the Ministry of Defence appointed a KPMG-led consortium to advise the government on how to lift the OFB out of its legacy socialist structures and to corporatise it. OFB unions at factories across the country have aggressively opposed the corporatisation drive. On the other hand, the effort to include private sector firms has largely been one step forward and two back, with several companies — both big and small — expressing willingness to invest in capacity to produce and supply ammunition, but require a degree of clarity and assurance of orders, since they do not have the financial cushion and leeway enjoyed by state-owned concerns like the OFB. What the numbers in the new Army report indicate is that things have come to a head. And with India’s forces massed on the border in a war-like situation that will almost definitely stretch into the foreseeable future, the Army hopes the glaring numbers will force a solution to its decades-old ammunition quality, shortage and assurance problems

Surface pressure distribution and wake streamlines for MK2 saras.

considerable progress was achieved in the design of Saras Mk-2 towards optimization of configuration. The drag reduction and aerodynamic efficiency, reduction in Operating Empty Weight (OEW) and increase in useful load, improvements in Flight Control System (FCS) and general systems were addressed. Significant progress was made with preliminary layouts, preliminary configuration documentation, CFD analysis, wind tunnel testing, configuration design, performance estimation, stability and controllability and critical load cases for structural design has been achieved for Saras Mk-2 aircraft.

Long back I had told this. Nirbhay was shelved only in paper, not on ground. It is just a way around the political bureaucracy for funding of the project.
All we have seen of Nirbhay is just in its test phase and its mock up. This can't be compared with something in deployed state or in advanced testing condition. If this new of Nirbahy in LAC is true (I am skeptical) then it means it is there under test phase.
Supplementary Info:
The last two test for Nirbhay were successful. It met all the parameters set by the army. The parameters set by Airforce and Navy were said to be lacking.
