Wow. Why I am getting a feeling of Deja Vu here?

No one cares about Gun range increment? Which gentleman in IA told you so?
If no one cares about increment in gun range, then why the FARP formulated in 1999 after Kargil, IA asked for more range in its future guns?
Why have the FH-77B which performed so well in Kargil seen a caliber increment in Dhanush?
Why ATAGS has seen further caliber increment then Dhanush?


If you want to talk about logic and all, we could talk more. But please don't bring whatever is in your mind with the tag that people in ground wants that.

who the hell gets a feeling of deja vu over a defence related discussion except for retards.

this is 2021 not 1999. if are on defensive detterence, you prepare according to your enemy. even if the chinki cheese dont use the newly made A-300 mbrl with range over 200km to 250km. they can still use BRE3/ FD140A warhead rockets with a range of 130km. while both the pinaka and smerch have only a max range of 90km. they can still attack leh from g219 road. of course we can destroy them after but still they get to attack us first while we dont have a detterence weapon at standoff distance.

talking about artillery guns. to have an increased range. you need to increase projectile velocity. artillery shells have a projectile barrel velocity of mach 3-5 depending on whether its howitzer or long barreled flat trajectory guns.
how the hell can you use flat trajectory guns in high mountain terrain. and how the hell can you increase the range of a howitzer, without increasing barrel length.

the more faster you want to launch the shells, the larger they have to be. because it depends on propellant surface area in contact. in otger words you cannot have a long straw like propellant. its should have a larger diameter, comparable to length maximum. l< or = to 7d. because propellant burning follows pioberts law. there is also helmholtz mixing at internal control surfaces of combustion gases during expansion. there are graphs of pressure vs time where it reaches a peak at certain milli seconds after which propellant burnout occurs before which the shell should leave the barrel.

long story short, the diameter of shell also has to increase if you want to increase length of barrel in turn also have more ammunition charges/ powder in turn the extra reinforcement at combustion section of the gun in turn more weight.

finally you will end up having a rail gun like schewer gustav weight 1350 tonnes with a range of 47km and rocket assisted range of over 120km to 150km (also by decreasing the explosive mass)

or the system 350 project babylon super gun by saddam hussein designed by canadian engg gerald bull. weight of 2100 tonnes with range of 1000km and 350mm bore.

or finally a soviet br 5 1939mortar of 280mm with a range of 10km weighting 18 tonnes.

good luck trying to achieve mach 7 to reach extended ranges cuz the steel or titanium barrel will be wrecked after a couple of shots. ramjet will only extend for a will since ramjet will kick in after some time of leaving the barrel. but still ramjet is mach 3 to 4 same as ordinary shell except there is continuous propulsion instead of a ballistic shot like the ordinary shells.

if you have any knowledge of rockect and spacecraft propulsions, turbomachinery for aircraft engines, armament engineering along with the ordinary mechanical engineering degree, you wouldnt talk nonsense.

Paf will use jf17 bander as cannon fodder.
So they are inducting it in large numbers 200+.
Sukhoi and rafale will waste their aam missile on these cheap jf17.
They are ready to loose 2-3 jf17 for single sukhoi or rafale
So their f16 or left over aircraft can target our high cost sukhoi and rafale when it will out of aam missile or busy fighting other aircraft.

You dant know , Jihad Fighter 17 has belt bombs and can do Sucidal attack on all parts solar system , LoL indian cow worshiper

The pic is from before April 1.

Besides, there's a good chance that with the present series of missile firing trials , Derby ER had been integrated with Tejas. Besides, some software updates to the mission comp, there's nothing to be done in order to integrate I Derby ER with acs that have already been integrated with the earlier Derby .

That’s the IR variant it’s flying with no?

DRDO conducts maiden trial of Python-5 Air to Air Missile


Posted On: 28 APR 2021 1:18PM by PIB Delhi



Tejas, India's indigenous Light Combat Aircraft, added the 5th generation Python-5 Air-to-Air Missile (AAM) in its air-to-air weapons capability on April 27, 2021. Trials were also aimed to validate enhanced capability of already integrated Derby Beyond Visual Range (BVR) AAM on Tejas. The test firing at Goa completed a series of missile trials to validate its performance under extremely challenging scenarios. Derby missile achieved direct hit on a high-speed maneuvering aerial target and the Python missiles also achieved 100% hits, thereby validating their complete capability. The trials met all their planned objectives.


Prior to these trials, extensive missile carriage flight tests were conducted at Bengaluru to assess integration of the missile with aircraft systems on board the Tejas, like Avionics, Fire-control radar, Missile Weapon Delivery System and the Flight Control System. At Goa, after successful separation trials, live launch of the missile on a Banshee target was carried out. Python-5 missile live firing was conducted to validate target engagement from all aspects as well as beyond visual ranges. In all the live firings, missile hit the aerial target.


The missiles were fired from Tejas aircraft of Aeronautical Development Agency (ADA) flown by Indian Air Force (IAF) Test pilots belonging to National Flight Test Centre (NFTC). The successful conduct was made possible with years of hard work by the team of scientists, engineers and technicians from ADA and HAL-ARDC along with admirable support from CEMILAC, DG-AQA, IAF PMT, NPO (LCA Navy) and INS HANSA.


Raksha Mantri Shri Rajnath Singh has congratulated the teams of DRDO, ADA, Indian Air Force, HAL and all involved in the trial. Secretary Department of Defence R&D and Chairman DRDO Dr G Satheesh Reddy appreciated the efforts of scientists, engineers and technicians from various organisations and industry.

Missile with lattice fins, dont know which one. May be for academical purposes.

[Rassil Krishnan]

Though the Chinks claim that they have 250 km MLRS rockets, but it is basically a type of tactical BM similar to that of Prahaar, Pralay.
There is only a certain range which can be acheived by rockets of a given dimesion. For 300 mm class MBRL rocket that range is between 90-120 km. That is the maximum that even Russian's could acheive with Smerch.And China does not have any magic fuel which can increase the un-guided rocket's range. With guidance kit this range can increase slightly, but with increase costs.
Above that it is tactical BM like Prallay, Prahar etc.
India got this tactical range covered but we need these missiles in greater numbers.

our problem is nos and induction,tech devlopment in certain areas is needed.but i repeat the issue always with indian procurement and modernisation is a woman in expensive shoestore like decision paralysis and not commiting to purchase the required bulk nos of equipment.this only changing slowly now,we have to wait and watch.

i repeat again we need mostly good enough workhorse solns to our problem and in good enough or more nos.not gucchi gear.our strategic needs if we are serious about it are going to rely on such a strategy and political commitment .

Anyone Notice Pictures of Rudram 1,2,3 in this tweet?

 

[Haldilal]

Ya'll Nibbiars and I thought only we had this problem's. From a troop carrier of 11 plus 1 driver with a 20 mm cannon and aluminum light weight scout and APC easy mechanicaly and less electrical and electroic equipped. It's was transformed in 15 years to the 6 plus 1 driver 30 mm cannon with missiles launcher and light aluminum heavy steel extremy mechanically and extremely complex electrooptics and survillence equipment's scout and IFV. From a million dollar per APC to 3 million per IFV. This is the just height of the idiocarcy.

Ya'll Nibbiars after seeing this. And for the FICV.
Don't ask to add a

40 to 80 mm Cannon.
Extra armour.
Missile launcher's.
More powerful engine.
Higher caliber Secondary armament's.
Side ports.
Amphibious capabilitie's.
MBRL's.

We are building a IFV not bardly's.

 

[Haldilal]

Ya'll Nibbiara does anyone remembers the name of the members who said that the FICV gun is insufficient, the armour is insufficient, need to add ATGM's on it's. Does any remember that?.
The RFI is for a IFV not an Small Tank.

 

[Haldilal]

Ya'll Nibbiara can some one tell me why the WhAP has those port holes when many have questioned it's effectiveness?.

 

[Haldilal]

Seen whole movie once , it's good .

Ya'll Nibbiara after seeing that film. The weapons test conducted are extremy detailed atleast on the Indeginious weapon's.
