This kind of weapon is arming to cover large area target, such as military base, logistic center, armor group, etc, etc. The strengths are: fast, cheap, large area covering. Accuracy is not top priority.



Well, that is the issue for any artillery regiment. Oh, we should say that is the issue for any short range weapon including cruise missile and ballistic missile.



Brahmos is not the answer for everything. It is precious, so it is expensive. It is a big waste to use Brahmos for those low value targets. That is why even US/Russia/China have supersonic anti-ship missile for quite long time, but they still developed long range rocket artilleries over 200km. Different weapon for different scenario.

Brahmos will be mainly used against enemy command posts,for attacking enemy infrastructure and supply line nirbhay will be usefull,after some modification and desi engine nirbhay will have a range about 2000 km at proper altitude and 1000 km in ground hugging mood.so, it can be used all over the tibet region

Guys,please share your thoughts about which i think is quite strange , the test of hstdv last year....the hypersonic test bed vehicle could be lunched at supersonic speed by a 2-3 ton booster instead of 15 ton ballistic missile...another aspect of this test is that agni1 should freeup it's payload at minimum 100 km. altitude instead of 5-10 km altitude...so,what is the purpose???

This is may be HSTDV will use as a Weapon payload in Agni missiles .100 Km is the boundary between Atmosphere and outer space, 30-32 Km is enough to avoid airdefence systems ,and most of the Hypersonic Weapons prefer 30-32 Km

 

[Bajirao]

in my opinion may be drdo devoloping a long range anti-ship missile using a ballistic missile as first stage and hypersonic vehicle as a second stage kill vehicle....in 2014 then drdo chief satish chander in a interview with sourav jha mentioned that drdo devoloping a 1500 km anti-ship ballistic missile...

Glide vehicles altitude will be 60-90 km..........while cruise missile altitude will be 20-30 km...

No, these cruise missiles have their limit, such as long response time: planning, self checking, warming. They are not suitable for these highly mobilised targets (i.e. moving armour column) or many small targets which are dispersed in a large area (I.e. infantry group).

So, as I said, different weapon for different scenario.

That was only smaller tech demonstrator for scramjet engine which was lasting 20 seconds.
The one need 100km minimum altitude is hypersonic gliding vehicle, different thing.

DRDO planning to doubling the range of MRSAM.


After its Developmental Partner, Israel Aerospace Industries (IAI) showcased Barak-8ER (Extended-Range) surface to air missile system with a range of 150 km which is extended variant of the Medium-range surface-to-air missile (MRSAM) named in Indian Air Force (IAF) and offered it to India, DRDO its Indian partner has decided to develop a local version of it with inhouse technologies instead of relying on the IAI.

DRDO has planned to test MRSAM missile system with an additional rocket booster which could have doubled its range from its current 70-80km to 140-150 km for the Air Force version which also requires minor changes to the mobile launch canister design and tweaking to the phased-array radars, command, and control system of the missile.

DRDO is also working on Surface to Air Missile which it calls as XRSAM and has a range of 250km and is designed to work with MRSAM-ER for the Air force along with MRSAM (70km). Official Renders of the XRSAM confirms that it has taken design cues from the IAI-DRDO developed MRSAM air defense system and probably will be using the same enhanced missile frame of the MRSAM missile and electronics like Active seeker and dual pulse motor which it has developed for the MRSAM program.

XRSAM was also seen with an additional rocket booster which leads to questions if the MRSAM-ER will be called XRSAM and the range will be bumped to 250km instead of 150km as rumored to be. Both Naval, Army, and Air force variants of XRSAM will be developed, XRSAM will have higher local content than the MRSAM which has many Israeli components in it including its Radar and command and control systems. DRDO has confirmed the development of XRSAM but has been mum on development of MRSAM-ER, Sources close to idrw.org have confirmed that one of the MRSAM missile launches was delayed due to lockdown in recent weeks.

Cross posting from wuhan thread,


DRDO has installed its Ultra Violet disinfection chamber at the Cochin International Airport in Kerala. The chamber would be used to disinfect the baggage coming at the airport. The chamber has been developed by a laboratory in Cochin: DRDO officials





Baggage at Kochi airport to get UV bath via DRDO’s disinfection system

Bengaluru: When the first batch of passengers land at the Cochin International Airport Ltd (CIAL) on Thursday night at 9.340 pm (IST), their baggage will pass through a UV (ultraviolet) disinfection chamber.

Developed by the Naval Physical & Oceanographic Laboratory (NPOL), a top-notch Defence Research and Development Organisation (DRDO) wing situated at Thrikkakara near Kochi, the UV system has completed all installation checks ahead of its first test.


NPOL is one of the leading labs of DRDO undertaking several Sonar-linked-technologies for the defence use, especially Indian Navy.

The need for such disinfection system was felt soon after the Centre decided to fly back the stranded Indians from different parts of the world.

CIAL officials felt that disinfecting the baggage in different and sizes using chemical spray wouldn’t be an effective idea.

“We are absolutely happy within the shortest possible time the NPOL scientists developed a system that can take care of our current needs. We have already completed the installation of the UV system to disinfect the baggage. We wanted a safe and efficient system and NPOL has delivered it satisfactorily,” CIAL Director A C K Nair told Onmanorama.

He said the airport staffs have been already trained about the protocols of the use of the UV system.

“Everything is set and our staffs are fully aware of the process, which is simple. The baggage will be shifted from the aircraft ramp to the UV tunnel before they go through the regular scanners ahead of the Customs hold,” says Nair.

Stop Imports

NPOL Director S Vijayan Pillai told Onmanorama that his team grabbed the opportunity to deliver a system that was already being prepared for the use for naval ships and submarines.

“What is being set up at CIAL is an extension of a UV baggage scanner developed for our own use and for Indian Navy as well. Post-COVID, we were ready with a UV system to disinfect the baggage of vendors coming to NPOL,” says Pillai.

According to him, NPOL will be installing a similar system at the entry gate as a precautionary measure.

The scientists had already readied a UV system for ships and submarines to disinfect the ration packs/ baggage before they got on-board.

“For CIAL we made modifications so that it suited the conditions there. The UV bath to the baggage is an additional step before the X-ray scanner. We wanted to install this at the ramp itself that opens out from an aircraft. Owing to vibration issues on the ramp, we decided to fix the UV chamber at the first point soon after the luggage gets unloaded,” Pillai said.


Intensity Trials

He said a prototype of the UV chamber has been already given to the Ernakulum Medical College (EMC), a designated COVID hospital, for intensity trials.

“The doctors at EMC have been tasked to guide us accurately as to how much UV rays are needed to disinfect a piece of baggage so as to combat coronavirus. We are awaiting the results and accordingly will make the modifications,” Pillai said.

He said the private industries in India will be playing a key role in large-scale production of the system.

“Hopefully, a firm like KELTRON should be able to take up the mass production of these systems. The idea is to avoid our dependency on imported systems. We are keen to make Indian products available,” Pillai added.

Based on the inputs from the EMC officials, NPOL will decide on the intensity of UV rays, distance and the number of lamps to be used in the system.

Kannur International Airport officials too have approached NPOL to install a similar device for baggage disinfection.

“We have proved our technology and installed the system within a day. It is now the turn of the industry to call the shots and make this in bulk so that we don’t have to depend on import,” says Pillai.

NPOL has been at the forefront of developing many products to fight coronavirus in the last two months.

The sanitizers made at NPOL are being used by the entire Kochi City Police force. The Southern Naval Command too had received NPOL’s hand sanitizers.
