Nuclear capable Prithvi-II test successful

[ALOK31]

BALASORE (ODISHA), DEC 20:
India today successfully test-fired its indigenously developed nuclear capable Prithvi-II missile with a strike range of 350 km from a test range at Chandipur near here.

The surface-to-surface missile was test fired from a mobile launcher in salvo mode from launch complex-3 of Integrated Test Range at about 9:21 a.m., Defence sources said.

The launch of the sophisticated missile, conducted as part of operational exercise by the Strategic Force Command (SFC) of the Defence services, was successful, they said.

“The missile was randomly chosen from the production stock and the total launch activities were carried out by the specially formed SFC and monitored by the scientists of Defence Research & Development Organisation (DRDO) as part of practice drill,” sources said.

The Prithvi-II missile, developed by the DRDO, is already inducted into the Indian Armed forces.

Prithvi, the first missile developed under India’s prestigious Integrated Guided Missile Development Programme (IGMDP), is capable of carrying 500 kg to 1,000 kg of warheads and thrusted by liquid propulsion twin engines, uses advanced inertial guidance system with manoeuvring trajectory.

congrats to us.

Congrats !!

India should look forward to export this missile to potential customers, a little degraded specification with 500kg payload and 300 km range is fully compatible with MTCR, even though we're not a signatory.

What are the fins for in the middle of the missile ? I thought a ballistic missile, be it an SRBM or an MRBM, wasn't all that maneuverable !

I'm not completely sure but I believe the fins are for stabilization, not maneuverability.

I'm not completely sure but I believe the fins are for stabilization, not maneuverability.

Yaaraa our Shaheen II, the Ghaznavid both lay in the same 'strike range capability' & our comparable to the Pershing series of US MRBM/SRBMs....none of them or the Pershing have these fins or at least not as pronounced ones !

I think it could be for something in addition to 'stabilization' !

Why are there so frequent tests of Prithvi? Either something fishy (new systems getting tested) is going on or we are trying to get rid of Prithvi stockpile. Hoping for some good surprises soon.

The bigger Fins are for stabilization as evident from Riveting...
But look at the lower small fins..You dont see riveting and don't see welding either..
Only one link is visible and it looks Movable..From that i am guessing that the lower fins are for maneuverability

The news says it is maneuverable, also, DRDO claims it has features to deceive ABM system.

Actually the purpose of these large delta is to provide Prithvi with a modified ballistic trajectory. After the initial boost phase which propels the missile to its apogee, it follows a glide trajectory towards its target during the descent. This allows for high manoeuveribility which can be used for both surgical precision and deceiving ABMs.

With the addition of modern Laser-ring INS and satellite navigation, Prithvi can now strike within meters of the intended target.

Prithvi has "strapdown Gudence" which s electronic equivalent of older Gimbals based INS used by our older missile Ghauri .

Strapdown systems
Lightweight digital computers permit the system to eliminate the gimbals, creating strapdown systems, so called because their sensors are simply strapped to the vehicle. This reduces the cost, eliminates gimbal lock, removes the need for some calibrations, and increases the reliability by eliminating some of the moving parts. Angular rate sensors called rate gyros measure how the angular velocity of the vehicle changes.
A strapdown system has a dynamic measurement range several hundred times that required by a gimbaled system. That is, it must integrate the vehicle's attitude changes in pitch, roll and yaw, as well as gross movements. Gimballed systems could usually do well with update rates of 50–60 Hz. However, strapdown systems normally update about 2000 Hz. The higher rate is needed to keep the maximum angular measurement within a practical range for real rate gyros: about 4 milliradians. Most rate gyros are now laser interferometers.
The data updating algorithms (direction cosines or quaternions) involved are too complex to be accurately performed except by digital electronics. However, digital computers are now so inexpensive and fast that rate gyro systems can now be practically used and mass-produced. The Apollo lunar module used a strapdown system in its backup Abort Guidance System (AGS).
Strapdown systems are nowadays commonly used in commercial and tactical applications (aircraft, missiles, etc.). However they are still not widespread in applications where superb accuracy is required (like submarine navigation or strategic ICBM guidance).

Strapdown system is these days easier to produce,but do need certain sets of calculations to be stored in the flight computer..
It is plausible that Both Pakistan and India are firing their old missiles to evolve their own versions of Software for the "Strapdown INS" and shift all their missiles away from the older Gimballs INS..
That may be one reason why we see both India and Pakistan firing same old missiles over and over again...

The picture of Prithvi II is cute...

Pakistan should buy 20 of these cute Prithvi Missiles for beautification of arsenal purposes....

^^^ Are you ok?

How can a missile be cute? Are you okay?
