Is the current MR-SAM/LR-SAM 90km or 70km?

Having longer range SAMs would be nice. Not sure if they will retrofit them into the P-15A/Bs or the P-17As.

The range of MRSAM quoted everywhere is 70km only.

There is a separate DRDO project to develop a longer range SAM under Program LRSAM which might be used on the capital warships.

70km

90km ones are almost identical to 70km ones in terms of dimensions, so they can be used without any modifications.

The 150km one's are also just slightly bigger so given the size of Kolkata and Vishakhapatnam we can easily add them but ya, some modifications would be needed nonetheless

Sir ji, one doubt.

We recently test fired naval version of AAD missile. But the range of AAD is only 40km. Also, the PDV missile is very bulky but it has a range of 150km. Do you think, are we gonna use them in future on our Next Generation Destroyers? Or they will only carry AD-1/AD-2?

I think you're confusing range and altitude.
Range of AAD is close to 200km, it's altitude is 40km. Same goes for PDV

Do you think, are we gonna use them in future on our Next Generation Destroyers? Or they will only carry AD-1/AD-2?

It solely depends on the induction time, if the missiles are tested before the start of ships production then we would definitely have a missile arrangement of VL-SRSAM < LRSAM < AD-1.
Not sure about AD-2

What engine does RQ-4 Global hawk uses? It looks like a god damn full sized plane and do we have any projects like this planned in near future?

RR F137; it's a full sized engine generally used on private jets

The range of Sam missile, depends on lot of factors. AAD missile has a range of 40 km against an incoming ballistic Missile. AAD would have a range of 250 km against a slow moving AWACS type of target

The obvious reason is the limitation of radar. By the time the radar detects target ballistic missile, tracks, the ballistic missile, locks into target, allocates the missile launcher, AAD missile is oriented, cleared, armed and fired and AAD missile accelerates, manoeuvres and travels 40 km. In the said time the target ballistic missile my travel 300 km.

 

[Raj Malhotra]

Max aero dynamic range as per my guess:-

Lrsam 120km (yes, not a mistake)
MRSAM 100km but faster than lrsam (Akash NG similar)
MRSAM with booster 120km -150km but faster than lrsam (ERSAM similar)
AAD 150-300km but faster than all three above (XRSAM faster than even AAD)

Now it makes sense why it looks so huge can we make one from kaveri ?it will be an amazing addition to cats program

Not quite accurate.

This limitation of radar only applies to sea-skimming missiles that take nap of the earth flight. These missiles are harder to detect because of the curvature of the earth but as the maximum speed they can attain is limited to only Mach 4; the time distance ratio is roughly 1:80. So for each one minute you take the missile would have gotten closer by 80km. So you still have plenty of time to react even if you do a late detection.
So basically; hard detection - easy interception.

But with ballistic missiles it's opposite; easy detection - hard interception.
As soon as a ballistic missile gains even a kilometer of altitude it pretty much negates the curvature of earth effect; it's now as visible as the sun. This is why even low powered counter battery radars are so effective...as soon as the projectile no matter it's mortar or artillery appears above the horizon you can pin point it's launch position. US can track a Russian ballistic missile as soon it's fired using its OTH radar. Similarly the ships AESA would be able to track a ballistic missile as soon as it enters it radar range.

Now coming to the time taken in launch...no, things now happen simultaneously instead of sequentially. For example missiles are not oriented and launched...they are launched without orientation, even actual target coordinate are not entered, only a vague direction is given to its INS and the missile is fired. While the missile is accelerating in the general direction, in the mean time actual interception point is calculated and uploaded via the datalink.

In 1970s, it took Sprint missile hardly 15 second from tracking a ballistic missile to intercepting it at an altitude of 30km.
Things happen in a blink of an eye.

MRSAM is the single pulse variant with 70km range and LRSAM is dual pulse upgrade with 100km range. And MRSAM is not faster than LRSAM; it's opposite. LRSAM retains much more energy in endgame because of the second pulse.

MRSAM is not used with booster, LRSAM (100km) is used with booster as Barak ER.

AAD's range is 200km and it's just marginally faster. It's bigger and heavier because it's used more as an space launch vehicle than a missile...it's sole emphasis is to go beyond the altitude of 40km; much more than any Barak.

There is close to zero info about XRSAM. Even the name XRSAM/ERSAM/Kusha is debatable.

Sir ji, I'm not denying anything which you have mentioned but according to some sources:

1. MRSAM is same as LRSAM and both are dual pulse with range of 70km.
2. The range of AAD is 40km and the altitude is 25km.

First thing first, there's very confusion regarding these.

The exact same missile with 70km range was inducted as LRSAM in Navy and MRSAM in Army/Air-force

Then the range of Barak 8 was increased to 100km using dual pulse motor. So now the land based system are called MRSAM or LRSAM based on whether they're upgraded one's or not. But for Navy all missiles are LRSAM no matter 70km or 100km.

See this pic, here it's written 70km but the pulse is dual.
How can the range be just 70km when the dual pulse is supposed to bump it to 100km?

It's simply baffles me how can someone compare AAD with PAC-3 MSE!?
A PAC-3 MSE weighs 400kg and AAD is 1,200kg. Heck even they themselves have written "800km class and 1500km class" and still comparing.

The closest missile to AAD would be THAAD, even that weighs just 900kg. It has a max quoted range of 200km.

Sir ji, here they are comparing THAAD with PDV.

Has anyone heard about Ronco safety India .,who claim to supply bullet proof jackets to Indian forces.

If this is approved we should just hang out heads in shame
