We need missile like ATACMS.

Pralay

 

[Arjun Mk1A]

So will we find new Indian companies who make carbines or we have some good ones ?I know sss defence has one

Don't put big hope. Let us see who are all fielding their prototypes. Our private talks a lot but deliver less. Lets wait and watch.

Why does one paint vehicles in a certain camouflage? And what purpose do reflective strips serve? Aren’t they both self defeating?

Those strips serve a purpose, when the dudes from China falsh a light, the strips will reflect the light back with 10x intensity blinding them.

Pralay

Actually the Prahaar fits more in the ATACMS category compared to Pralay, if I am not wrong, DRDO was working on a mobile 8x8 platform capable of carrying 2 Prahaar missiles instead of the standard 6 on the 12x12 truck, don't know what happened to that.

Camo might be for the terrain masking from aerial and the reflection strips for usual role but i don't think they doing suprise raids using it.

The article said the decision will be taken in upcoming weeks so idk if its correct I would love for it to be

Dude, I don't care if he is pakistani or indian or whatever his nationality is. He is just shit-posting every damn time only to promote his own channel. If I remember correctly, he was previously warned about this by mods also. Yet, he continus to do the same.

It is ok because he keeps the posts in the relevant threads and his posts are not inflammatory.

The vehicle is a Quick Reaction Fighting Vehicle(QRFV) it is definitely going to be doing raids.

Pralay

I mean we need missile like ATACMS which can fit inside the pinaka rocket pod. Chinese have King dragon missile similar to ATACMS. Pralay and Prahaar(also variants) are longer Missiles.

Compare it with Barak-8 VLS, then we can get some clarity

Missile	Barak-8	VL-SRSAM
Mass​	275 kg (w/out booster). I couldn't find booster weight.	154 kg
Length​	0.5 m (w/out booster)	3.84 m
Diameter​	0.225 m at main missile body 0.54 m initial-stage rocket motor, Barak-8ER version	178 mm
Warhead​	60 kg	High-explosive pre-fragmented HMX/PU - 15 kg
Detonation mechanism​	hard kill (proximity fuse)	Radio proximity fuse
Engine​	solid fuel smokeless dual-pulse rocket motor	solid fuel smokeless single-pulse rocket motor
Wingspan​	0.94 m	254 mm
Operational range​	0.5km-100 km	40 km - 50 km (depending on target)
Flight ceiling​	16 km	15 km
Maximum speed​	Mach 2	Mach 4.5
Guidance system​	2-way datalink using Wireless Communication Syste, (provided by Israel) Active RF seeker (provided by Israel)	Mid-course: Fibre-optic gyro based inertial navigation system with mid-course update via data-link. Terminal: Active radar homing
Launch platform​	8 cell VLS module	VLScan hold forty missiles in a twin quad-pack canister configuration carrying eight missiles each for hot-launch
Features​	Two way data link (GPS S band) The missile receives mid-course guidance updates from the MF-STAR radar Active Radar Seeker Missile 360 degree coverage Smokeless propulsion Thrust vector control Dual pulse propulsion Vertical Launch Multiple Simultaneous Engagements Point defense anti-ballistic missile	Two way data link Active Radar Seeker Missile 360 degree coverage Smokeless propulsion Thrust vector control Vertical Launch Multiple Simultaneous Engagements Point-defense system

Astra BVRAAM/VL-SRSAM seeker is heavily influenced by Barak-8 seeker.
Originally indigenous content in Astra was 50% which has now been increased to 90-95%.

One can pack more VL-SRSAM compared to Barak-8. VL-SRSAM flies significantly faster. VL-SRSAM is also significantly cheaper.
Downfall is the range, limited energy in terminal phase (lack of second pulse) and probably reduced capabilities (VL-SRSAM is currently not proven to have ABM capabilities).
Currenlty I couldn't locate minimum engagement parameters for VL-SRSAM.

VL-SRSAM doesn't need ABM capabilities. By the way I think you misunderstood my question...I asked to compare the Barak-8 VLS & rumored VLS on that Rajput class destroyer.

Neither ATACMS nor the Fire Dragons fit into their regular rocket pods. And Prahaar has smaller dimensions than both.

Are the radars indigenous?

 

[Chinmoy]

Ok, a very basic question.
Astra Mk1, a single pulse solid propellant rocket has max range of 110 km with Max interception speed of Mach 4.5
Meteor, has a max range of 200 km and Max interception speed of Mach 4.0+
SFDR, meteor category missile has max range of 340 km and according to DRDO poster has max interception speed of Mach 3.6.
So my question is, are we compromising with speed to achieve greater range, or there is some other engineering limitations coming to play?

Don't read much into 340 km range. It could be achieved if launched from 20 km altitude or 65000 feet. As of now we don't have any fighter to fly at that altitude.
So the practical range would be anywhere in between 190 to 230 km max.

And the nonsense RR starts again.

How come IA is ready to induct drdo carbine without long trails

ARDE carbine is something which has undergone trial and seen failure.

Very much....
