Hmmm... Interesting.

Sadly we would never know how effective it is.

There would be only speculation. But that is good enough to make PLAN and non existent PN shit.

Did they test 120g projectile? this is huge!

Yes according to them they did

Wing morphing demonstration

FlexSys is a US company which has prototyped and showed this very concept on a working plane, it's good that DRDO is also pursuing this technology.

Fun fact: The founder is Indian.
But what's even more impressive is how the USAF supported this relatively new technology from a no name startup through years of funding and for years on end to its eventual completion.
Our military and MOD should emulate this.

I think I read somewhere , DRDO implemented some measure of limited morphing technology in the fins of its missiles

Some info on DRDO AIP

Endurance mode user trial of drdo Land-based Prototype (LBP) for Air Independent Propulsion (AIP) System for submarines for a period of 14 days was successfully completed at Naval Materials Research Laboratory (NMRL), Ambernath, on 2 December 2017.

The AIP, developed by Naval Materials Research Laboratory (NMRL) is a 250 kW Phosphoric Acid Fuel Cell (PAFC) based system, that allows up to 14 days of underwater endurance for a submarine running solely on power supplied by this system.

NMRL’s AIP system incorporates a set of innovations that make it a rather contemporary system. For one, NMRL’s AIP package has an onboard hydrogen generation plant, which produces hydrogen ‘in situ’ that too without any combusion, unlike many other AIP configurations where hydrogen for a mission has to be carried on board in tanks.

PAFC has much longer service life than any other commercially viable FC type and has much better tolerance to impurities in the reactants used even when compared to polymer electrolyte fuel cells (PEMFC). But, PAFC operating temperatures are usually higher in comparison to PEMFC and overall power to weight ratio is lower.

The PAFC is designed such that series/parallel stacks can be used for power generation levels of up to 500 kw, this modularity of NMRL’s AIP solution enable it to be used in submarines other than the Scorpene as well. This also naturally increases the survivability of the system, since even if one of the modules fails, the control system for the PAFC stacks can reconfigure the remaining operational units to continue to supply power output, albeit at a reduced quantum.

bmp-2 mine clearing variant

The Surface Clearance Device (SCD) clears surface laid mines and threats found within the path of the full width of the vehicle, from roads, tracks and rough terrain to produce a cleared route for follow-on vehicles. Independent segments of a full width blade follow the ground contours to move threats wide and clear of the vehicle. The SCD is fitted with a Full Width Mine Disrupter System (FWMDS) which is designed to tumble and detonate any tilt mines encountered, increasing overall protection and maximising operational efficiency. An Magnetic System Duplicator (MSD) can be fitted to help protect the equipment from the effect of magnetic influence fused mines.

RUDRA looking awesome....

The EO pods are missing , looks like it was removed due to non availability of ATGMs and to save on maintenance costs etc

Should come back once HELINA and SANT becomes available

These containers allow for resupply of spares & stores to ships deployed more than 2000 Km from coast.

Mortar carrier...................
Good to see they are using mobile non LOS weapons together with mobile direct fire weapons. Should prove effective to counter entrenched ATGM teams behind bunds and ditches etc

Army develops its own armed UAV, more advanced ones to follow


NEW DELHI: With Army Chief General Bipin Rawat here on Friday pushing for defence innovations by armed forces personnel for development by the industry, a team of soldiers have created an armed Unmanned Aerial Vehicle for the army, which has been a long pending requirement.

The UAV, known as a quadcopter by the team of two army soldiers who developed it, has been used in live operations along the Line of Control between India and Pakistan and counter-terrorist operations in Jammu and Kashmir. What makes this quadcopter important is that not only the army, but also the other defence services, don’t have armed drones. Separately, the army has also found that the Indian industry has the capability to develop a more advanced version of this UAV, which is a ‘Make’ (equipment developed and manufactured by Indian vendor) case being analysed. Demonstrations of some models could be held next month.

Although last year the US agreed on supplying armed drones to India, the army is taking steps towards having indigenous armed UAVs. This includes a development effort on its part. The group of two soldiers belonging to the 21 Sikh regiment have created a quadcopter that is capable of carrying out day and night surveillance and dropping grenades on targets.

Sepoy Gurpreet Singh and Sepoy Amrik who developed the UAV explained that it was created by them in 2015. The quadcopter was initially used for surveillance and was later modified to include the weapon system and was recently tested for dropping grenades.

Explaining how it works Amrik said, “The quadcopter can lift three grenades or two kg of payload such as ammunition, IEDs and first aid. We manually control the UAV through a remote control. It can also be used automatically, wherein we feed the coordinates on the laptop and it navigates to the areas and drops the grenade after unpinning it. It also has day and night surveillance.”


“All these ideas were given by our Commanding Officer Colonel Ashutosh Mehta. We had made a basic flying machine and he told us to use it for surveillance and weaponise it,” said Gurpreet.


Sources who are privy to the development said that the “concept is good” and can be taken forward. “It is very heartening to note that soldiers on the ground are coming up with innovative solutions either to improve the existing system or coming out with new systems that can be taken up by the industry for further development...88 such innovations have come up in the last one year. Out of which we have identified 60 of them to be discussed with the industry to move forward with them on further development,” said General Rawat at the Army Technology Seminar 2019, where the quadcopter was displayed.

The army separately has also reached out to the Indian industry to provide a more advanced UAV. In one of the compendiums of problem statements released by the Army Design Bureau is the requirement of developing a hexacopter or quadcopter for use along the LoC and Line of Actual Control between India and China. The army also wants that it is able to carry day and night surveillance and can engage infiltrating terrorists by dropping grenades and IEDs.

The army calls the quadcopter-hexacopter combo as the seeker-shooter combat management system. It is based on the quadcopter functioning as the seeker to undertake surveillance, while the hexacopter carries the payload to engage the target, according to the problem statement. Sources explained that the army is looking at either having the seeker and shooter system together or separate. Some companies have offered single indigenous seeker-shooter system and their demonstrations could be in February.

The army is also looking at the possibility that the UAV is able to “loiter”, which unlike the quadcopter developed by Gurpreet’s team, will be able to more accurately throw in grenades and fire ammunition through loopholes in bunkers and windows. “The entire system is one of the 15 ‘Make’ cases being analysed by the army. The army has found that the industry has the capability to make them. Some of these cases would soon be launched under the ‘Make 2’ route,” said sources.
