Following 18 years of hardwork, state-owned DPSU Hindustan Aeronautics Ltd on July 4 received 'restricted' type-certification (for flight operations up to medium-altitudes) from the Brussels-based European Union Aviation Safety Agency (EASA) for the Dhruv ALH twin-engined 5.5-tonne helicopter. Dr D K Sunil, Director (Engineering, R & D) of HAL received the type-certification documentation in the presence of Filip Cornelis, EASA Director for Aviation, Directorate-General Transport & Mobility; Luc Tytgat, Strategy & Safety Management Director of EASA; S K Mishra, Joint Secretary of India’s Ministry of Civil Aviation; and Vikram Dev Dutt from India’s Directorate General of Civil Aviation (DGCA). HAL had begun work for obtaining such type-certification back in July 2005.
The EASA type-certification establishes that: 1) HAL is capable of designing helicopter platforms meeting the stringent European airworthiness certification requirements. 2) HAL-developed manufacturing processes for the Dhruv meet the stringent European airworthiness certification requirements. 3) All the Dhruv ALH-related type-certification documentation prepared by the DGCA over the years has worldwide endorsement from EASA. 4) Civilian variants of the Dhruv ALH will from now on be able to compete on par with its global counterparts worldwide. 5) Domestic rotorcraft operators will from now on be able to obtain hull insurance for the Dhruv ALH civilian variants from commercial insurance companies, which was impossible before.
This now sets the stage for HAL to obtain similar airworthiness type-certification for the civilian variant of the single-engined Light Utility Helicopter (LUH), now being series-produced at the greenfield HAL facility at Tumakuru; and for the Hindustan-228 STOL twin-turboprop commuter aircraft.
The military variants of the Dhruv ALH adheres to the following FAR/MILSPEC standards:

New SSN design or internet fanboys stuff...
Dear Prasun, in recent months, there had been talks in further order for three more Scorpene Subs. With the last contract, tech transfer of 40% had been achieved in the sixth submarine as per media reports. In short, Which all critical tech should india ask for from Naval group while ordering three more submarines. In short which all tech we need from Scorpene sub to make our sub building industry self sufficient?
ReplyDeleteSir, why the word restricted and (for flight operations up to medium-altitudes)?
ReplyDeleteIs HAL going for full and high altitudes too if those terminologies exists ? High altitudes not required as India is the only operator in those heights?
@prasun da
ReplyDelete1. i really feel HAL really missed trick by not going for stretched versions of SDo228
2. btw what was the new slbm test abt
3. what about the new SSN design doing rounds, it says it will have VL & TT launched slbm, how come
thanks
Joydeep ghosh
Sir, Good, state govt and industries can order these instead of imports ?
ReplyDeleteRegards,

Answers to the above questions by Sriman Joydeep Ghosh by PKS will am sure appear in the next For My Take under - "The woes of indigenisation: missed opportunities and myriads of configuration "- Oh no have even given a ready made title!!!
ReplyDelete@prasun da
ReplyDeletewhether you like it or not days of short high intensity limited battles with nuke overhang are over. even it with nuke overhang it will be long drag attrition war for India whether it is with china or with Pakistan and will be spread across the entire border stretch from gilgit baltistan to kutch and aksai =chin to Arunachal, as such focus should be now on low cost rockets and missiles like air launched guided pinaka, 60 to 250 km range rocket and arty like smerch, pinsaka and more
thanks

ReplyDeleteHI prasun
HAl awaits the russians for the su30 upgrade. In what way can they stall us. will they insist on their test pilots flying also as an excuse to know what we have done?
test flying done in russia or india ?, will it give a hands off lo lo lo terrain foll capability like the rafale as this is possible due to the aesa radar?
how can they integrate the aesa radar input for that to the FBW system as both will have a different bus protocols.
To SIDHARTH: LoLz! That is the silhouette of a Virginia-class SSGN!
ReplyDeleteTo PRUDHVI: I had already uploaded slides & schematic diagrams of all that has been licence-built by Indian vendors for the CM-2000 Scorpene SSK here:
http://trishul-trident.blogspot.com/2017/01/second-cm-2000-scorpene-ssk-of-indian.html
The challenge is not about SSK-building, but about SSK design, for which several data-points are reqd. For shipyards like MDSL, this should not be a daunting task at all since it has already licence-built two different types of SSKs to date. All that is now reqd is a degree of self-confidence to venture into uncharted waters by undertaking in-house deign of a new-generation SSK with the help of the IN’s Warship Design Bureau, which now appears to be happening with the commencement of Project 76 without waiting for Project 75I to commence, judging by this interview of MDSL’s CMD:
https://www.youtube.com/watch?v=pYYErSBG-dY&t=16s
To DASHU: That’s because the Indian type-certification reqmts & documents, even though based on US Federal Aviation Regulations (FAR), were prepared by CEMILAC & not by the DGCA. The DGCA therefore is still in the process of converting the CEMILAC-specific documentation for flight operations into civilian-compliance documentation. However, the EASA certification for HAL’s industrial manufacturing & MRO protocols is unrestricted & total.
To JOYDEEP GHOSH: 1) There never was any stretched variant of the Do-228 STOL commuter twin-turboprop. There were only 2 follow-on versions, the Do-328 regional commuter STOL twin-turboprop & the Do-328 turbofan-powered STOL commuter aircraft. 2) Only IDIOTS will clam that a SLBM test-firing was conducted from ITR Balasore. Why should any SSBN or SSGN go to Balasore to test-fire any SLBM? All previous test-firings of SLBMs & even the BrahMos-1 from submerged SSGNs were conducted in the central portion of the Bay of Bengal. Hence, all indications are that the latest missile test-firing was not of a BM of any kind, but rather of a solid-fueled missile probably carrying a powered hypersonic vehicle & no, it wasn’t the 3M22 Zircon/Brahmos-2K either, rest assured. 3) That is the silhouette of a Virginia-class SSGN. The SSGN design given to India by Russia 3 decades ago was fully-developed & optimally engineered & there’s nothing more to be done. BTW, any design optimisation of any underwater vehicle is done here (the first 3 slides in this thread):
https://trishulgroup.blogspot.com/2009/08/schematics-of-atv-scorpene-ssk-project.html
To VENKY: Hopefully, especially for air-ambulance services.
To JOYDEEP GHOSH: I had already alluded to this here:

ReplyDeleteBloody learn to spell and read correctly first- JAYA DEEP? JOYDEEP and yes I am the one who posts questions here and elsewhere and I summarise opinions For My Take. There is no room to add Reference so authors I borrowed ideas from are not mentioned. Thelast Submarine idea came from Ajay Shukla/ Shiv Aroor / Vijay Thakur in case you were wondering. I sum up like that so others can get all these different ideas in one place plus makes me look like an Expert LOLLZZZ. Sorry you got me so angry I forgot my password and can't log on to Blogger but it is ME.
Prasun,
ReplyDelete1- why develop a 120mm gun when 130mm is the new trend --https://idrw.org/arde-to-develop-advanced-main-gun-for-next-generation-main-battle-tank/
2 - like it or not but the fact is jf 17 has buyers --https://idrw.org/fighter-aircraft-from-pakistan-iraq-fifth-country-to-initiate-deal-for-jf-17/.
3-if WDB & MDL are working on desi ssk & considering the recent german & french offer of SSK's what is IN's plans how many SSK's does it plan to have. isn't it wiser to develop next gen SSN's--https://idrw.org/wdb-and-mazagon-dock-shipbuilders-to-develop-next-generation-diesel-electric-submarine/
4- https://idrw.org/india-awaits-russian-approval-for-su-30-upgrades/ -- any stumbling blocks here? shouldnt IAF AL$!S engines atleast for a few aquadrons once payment issue is sorted as future upgrades would call for more power reqmts..
@prasun da
ReplyDeleteif i remember correctly long back i had said why doesnt India develop SLAMRAAM

ReplyDelete1. India Amry hasd issued tender of SPAD-GMS with high speed guns and only 6 missiles, isn't the missile number too small as PANTSIR has 12 missile
2. DRDO is developing new generation 120 mm smoothbore gun isn't the current choice is to go for 130 mm smoothbore
thanks

ReplyDeleteSir, what's the meaning of writing 560 + 1500 long range guidance kits in above post regarding BEL order?
ReplyDeleteAlso what's the range of the long range guidance kit?
ReplyDeletejoydeep
i am shocked by your infantile response, both of us have been here a long time . i was
expecting a logical technical rational response. i rest my case
To DHANU: Although the arrested DRDO chap did break the law by having such WhatsApp chats, going by the disclosures in social media about the chat contents, it seems he did not reveal anything that’s not in the open domain. For he was involved with developing electro-hydraulic elements of TELs for various types of missiles & so he would not have had access to the performance parameters of the various guided-missiles.
ReplyDeleteTo RAD: The Type 877EKM SSKs each have a displacement of 2,300 tonnes, a maximum diving depth of 300 metres and a top speed of 18 Knots. They are able to operate solo for 45 days with a crew of over 50. Of the 10 such SSKs originally procured from Russia, INS Sindhurakshak was lost in an accident, INS Sindhuvir was transferred to Myanmar and INS Sindhudhvaj was decommissioned in July 2022 after 35 years of service. INS Sindhukirti is currently at the Vizag-based Hindustan Shipyard Ltd (HSL) for a normal refit lasting 22 months at an overall cost of ₹934 crore. INS Sindhuvir’s medium refit and life certification (MRLC) lasted for 27 months. Despite this, the IN in 2018 selected Severodvinsk-based Russian shipbuilder Zvezdochka for MRLCs worth Rs.5,000 crore for four Type 877EKMSSKs. One of these, INS Sindhukesari has already come back to India, while the upgraded & refurbished INS Sindhuratna reached Mumbai after sailing for 97 days and almost 10,000 miles with two port calls in between. The SSK faced transportation issues in the backdrop of the war in Ukraine. The initial plan was to move it by a transport dock ship directly from Russia, which did not materialise, following which the IN tried to sea transport the SSK to Norway and then via a transport dock to India, which also did not materialise. Following this, the IN decided to sail it directly on its own. INS Sindhuratna next undertook a gruelling 97-day return passage through the Norwegian Sea, English Channel and the Mediterranean Sea, and arrived Mumbai on May 16, 2023.
If The IN persists in sending the Type 877EKMs to Severodvinsk instead of utilising HSL’s MRLC expertise, the all such SSKs will have to sail back on own power, thereby resulting in decreased service-lives. Consequently, the Russia-supplied SSKs of both India & Vietnam are now in a fix.

I had replied to your previous queries on LANCET & APS in the previous thread.
To PARTHASARATHI: I had already explained before that usage of Light Tanks anywhere along the LAC is a no-brainer. Even the PLAGF hasn’t deployed such light tanks anywhere along the LAC, choosing instead to field ZTZ-96 & ZTZ-99A MBTs.
To JUST_CURIOUS: 1) Don’t fall for FAKE NEWS. If you want to follow the latest trends like this:
https://bulgarianmilitary.com/2023/07/07/french-leclerc-tank-became-63-tons-driver-shell-magazine-removed/
3) Not more than 16. 4) Sukhoi OKB’s type-certification is awaited. 5) Because Erdogan is far smarter & its resorting to Chanakya Niti’s stratagems, UNLIKE India’s ‘Netas’. 6) It is FAKE NEWS.
To JOYDEEP GHOSH: No, your recollection is totally wrong. Here’s what I had stated:
http://trishul-trident.blogspot.com/2021/12/from-astra-1-bvraam-to-qr-sam-to-sr-sam.html
1) Here is the IA’s RFI:
https://indianarmy.nic.in/writereaddata/rfi/966/989b78a5-e9c6-4f51-ba69-93236d2d4998.pdf
MoD is a totally confused institution. On one hand it has already selected L & T's Sudarshan system (240 guns) for the IAF & had also issued an RFI for 220 air-defence guns and 1,41,576 rounds of ammunition for the IA.
2) It is FAKE NEWS.
To HARSH: 550 in the first tranche & a total of 1,500 in all to be procured. Range is same as that for Griffin-3 LGB.
ReplyDeleteHi prasun
given your negative view of future submarine collaboration with russia what about the s-4 and s-5 help to india, what about the reactors?, the zircon collaboration. etc
or will we go the western way with french help?
Personally i think the days of tank warfare are over until there is a fool proof way to jam and stop the lancet type drones. china will be glee fully waiting for indian tanks in ladakh or else where,
i have to commend the drdo if the developed the ramjet for the sfdr missile.
will russia insist on their test pilots flying the upgraded su-30 to know what we are up to? do we have a choice?
dont u think that india should on a war footing find a solution to the lancet type drones and go in for APS wiht all urgency rather than acting after out tanks are busted like in ukraine?
Prasun sir,
ReplyDelete1) According to this,
https://twitter.com/someplaosint/status/1677920832016855040?t=C7Tqo6AmMy6dhDAx5jkgUQ&s=09
The Type 346 radar and HHQ-9B missile combo is better that MFSTAR - Barak-8. Do you agree?
Which system of these two is better for shooting down incoming salvos of supersonic Anti Ship cruise missiles?
2) Apart from the smerch 9M55K cluster munitions, CBU-105, and pinaka DPICM, does india have any other cluster weapon?
Do we have any 155mm cluster artillery?
3) According to recent reports from RUSI russia has one electronic warfare system, for every 10km of the front,and they are having a severe effect on the ukrainian war effort.
What is the condition of our electronic warfare systems? Do we have enough?
4) Does india possess any vacuum bombs/weapons? If so what are they?
(BTW I am not the harsh that asked the question at 10.39pm, I guess there are two harsh(s) here)
According to you... when would the deal for 26 naval jets be inked?
ReplyDeleteSir please answer in details, recently China may have ordered irans shahed 136, it may have ordered 50,000 in quantity
ReplyDeleteHow will India's multi layered will handle such massive saturation attack in absence of CRAM like system?
In future are we planning to buy loitering ammunition in huge no?
How will the west like US will response to thousands of shahed 135 attacking battery of PAC3?
Hi Prasun,
ReplyDeleteWhat air to ship/Ground armament will Rafale M carry in IN?
Can it carry and fire Brahmos in anti shipping role?
Will the three new Scorpene subs on order be equipped with DRDO AIP from construction stage?
@rad bhaya
ReplyDeletewhatcha talkin
i ask only when i need clarity
i never question others reason or logic
if dada feels he responds
pls don't add conjectures
thanks
Joydeep ghosh
To RAD: If a solution is found on the payments mechanism, then all existing & future procurement projects will continue as planned. No Russian test-pilot will be reqd to fly the Super Su-30MKIs. IAF’s ASTE will handle it. LANCET-type loitering PGMs are already available in India, like this:

To HARSH: 1) It is FAKE NEWS. 2) Of course. It was all explained here:
http://trishul-trident.blogspot.com/2018/10/from-prithvi-to-pralay.html#:~:text=Built%20by%20KBM%2C%20it%20is,and%20electro%2Dmagnetic%20pulse%20detonation
3) Yes. 4) Thermobaric weapons. The IAF has such bombs & Arjun Mk.1 MBTs can fire 120mm thermobaric rounds.
To SRISHTI: During state visits, only announcements are made, while contracts are inked later, just as was the case for the IAF’s procurement of 36 Rafale M-MRCAs.
To SANTOSH: LoLz! It is the China-developed ASN-301 anti-radar drone from which the Shhed-136 was derived! Not the other way around. India too has such drones like Harpy & Harop.
To VED: The same as that for the IAF Rafale. Later, the BrahMos-NG, if available, can also be carried. The 3 new Scorpene SSKs will not come with AIP from the outset since the DRDO-developed MAREEM AIP will not be available till then & will become available only by late 2028 after undergoing tests on board a refurbished & refitted INS Kalvari starting from 2026.
But a conflict of interest can well develop because of this:
https://corpwebstorage.blob.core.windows.net/media/48506/2023-07-10-lt-and-navantia-sign-a-teaming-agreement-for-project-75-india-submarine-program.pdf
https://www.navantia.es/es/actualidad/notas-prensa/navantia-acuerda-con-larsen-and-toubro-ofertar-conjuntamente-submarinos-a-india/
On one hand L & T will be promoting NAVANTIA’s AIP solution for the 6 P-75I SSKs while on the other hand L & T is the prime industrial contractor for building the MAREEM AIP for the IN’s existing 6 CM-2000 Scorpenes!!!
Why naval rafale being proritized while air force squadorn levels are at alarming levels
DeleteHi Prasun,
ReplyDeleteAs per my understanding P75I is doomed if three additional Kalvari is procured along with 24-26 IN Rafale. This might be a quid pro quo for getting required technical assistance in our SSN programme for nuclear reactor or may be some other strategic project not in public domain till now.
Someone is using names of existing people here hence doubling up and causing confusion.
ReplyDeleteI don't understand the Indian Navy mindset. Apart from AIP, what other submarine has which an upgraded Scorpene SSK cannot have. Why should we go for a new hull design as most of existing infrastructure will not be usable for new design hull. As you said India's requirement for 16 SSKs can be full filled with 9 Scorpene and existing fleets. Will it be technologically effective if India goes for 6 extra subs will new generation subsystems on Scorpene hull?
ReplyDeleteSudipta
Prasunda,
ReplyDeleteIndia is having only 6 Destroyers to protect the full shore line. And if there are two Carrier battle groups, then there will not be any Destroyer avaliable for any emergency! R class is now museum piece and Delhi class is more or less obsolete, even after retrofit. China is making a Destroyer within two years ( keel laying to Handover) , where as our Nilgiri class was ordered in 2017, Keel was laid in 2019 and still first one is not even ready for even Harbour trials. Delivery is atleast two years away.
Considering same we must try LNT for capital ship building. Even Cochin Shipyard is also a better choice. We must end monopoly of MDL.
Best regards
India has 7 of the latest kolkatta and vizag class destroyers ... Not 6 ... Also the older 3 destroyers have been upgraded ...

ReplyDeletean honest assessment
1. when will this brainwashing through whatsappuniversity and other social media will stop
2. when will this hindu khatrey mein hai & love jjihad land jihad vya[par jihad crap will stop
3. will we ever see a stop in this mutra visarjan, stone pelting if riding a horse or bike by brahmin and other higher class people on adivasi, sc/st
honestly as per me Mr. marketer and his organization with its political arm and all other offshoots dals has used his divisive skills to burn my country and succeeded in manipur uttarakhan uttar pradesh
the rhetoric of Mr. marketer I clearly remember he said previous govt should have shown laal ankh and claimed'i will not tollerate' this has fanned intolet=rance against everything
so much so that army has to issue pension stop warning to ex men if they continue to sully its secular image unfortunately bjp/rss from erode secular fabric of Indian armed forces, today many veterans instead of holding armed forces ethos high are bareing their communal fangs & trolling abusing harrassing others who dont agree to their so called nationalist agenda like itcell
got any idea
thanks
Joydeep ghosh
Now I do agree with Joydeep even though he will face the wrath of many such as Chan Chat and the like. There is no doubt India needs to assert itself against the China-Pak threat. But clever politicians who care only about their pockets are very cunningly using this position to exploit the country. They claim patriotism and yet denounce the constitution that says India was formed as a democratic, sovereign, secular, socialist republic. The Khalistanis too are exploiting this business of no Lal Tika no Indian as abuse of human rights. It is not officially Indian policy to discriminate but there is absolutely no doubt, at the grassroots level, it is very dangerous to not subscribe to the neo Nazi like views or to speak out against it. To make it worse, there is a total inept party like the Congress - with no ideas.
ReplyDeletePrasun Sir,my understanding is that our relation with Malaysia is not all that good and they are close to China unlike Vietnam.However ,there was defence cooperation visit very recently.What is the purpose and is there any real outcome?best regards

ReplyDelete@Jaiswal Dhillon
dear bro idea of undivided india was of by Congress whereas hegewar, golvalkar, mukhuty, savarkar led RSS, jan Sangh/BJP with Muslim leaf=gue was to divide congress on religious lines
infact they both joined hands to form provincial govt in singh and undivided bengal before independence in 1940s
post independence it was nehru and congress that chose not to focus on religious dogma and instead work on development that is how we got IIM, IIT, REC, RCE, AIIMS, SAIL, IAS, IPS, IES, IFS, NTPC, NHPC, and more
even after passing of the great man Nehru we had shashtri, indira, rajiv, narsimha, Manmohan who led the country into
I can go on endless but just 2 things
1. be it steel plant tech on being requested by Nehru in 1951 after being told by UK especially guys like Churchill and others Eisenhower denied us and said that we will remain friends but can't help you. UK even persuaded Stalin not to help but his death changed all in 1954 Nikita Khrushchev quickly asked Nehru find me places and i will provide all help and that is how bhilai steel plant came out of nowhere in 1956 even an entire industrial zone was created around bhilai steel plant whereas other plant were setup in and around existing industrial zone.
2. also when in mid 1980s when India was suffering from back to back draught rajiv gandhi went to USA asking for super computer to predict weather and rain. reportedly they agreed for 40 millions but warned that if it is used in any other act we will crush you so hard you won't be able to make a safety pin(they said else but actually meant that) a furious and insulted rajiv came back and asked cdac chairman who reportedly asked for 6 months, 40 crore and no question asked supply line. 8 months later we had paramount super computer. reportedly russia again helped with material support and expertise along with little help from probably Israel
2 of the reasons beside weapons as why India will never ditch Russia though
anyways this pretty much shows what congress has given India lot by way of ideas
thanks
