Prithvi is liquid fuelled. It is kept under fuelled condition. After fuelling it has a shelf life of 10 years.
The concept that liquid fuel missiles have to be drained of fuel in 2 hours is totally outdated. It is true for cryogenic fuels. Even in 1950's Soviets had SA-2 SAM, which had a liquid fuelled second stage (fuelled by red fuming nitric acid and kerosene), even that was storable! Rocket fuel technology has progressed since then, so is the mettlurgy!. DRDO has moved from high tensile Steel to Marraging steel and now to composite motors for it's missiles.
I do have DRDO press release referencing shelf life of Prithvi under fuelled conditions, but I have to dig it out of my hard disk.
Oh DRDO... ? Will be waiting for the link. This I've got to read.
Maybe in the meantime, Grand Danois or some other more knowledegable members can share their knowledge.

Well it is the DRDO which builds PAD not North Korea, so info has to come from them, it will take me some time to search for them.
On the other hand why bother.
Instead of depending on others to do your reasearch why not use the internet to do a bit of search on Nike hercules, SA-2, SA-5, A-35 and other missiles. All these were SAMs and ABMs you know.

No. You are comparing a Surface to Surface missile and in this case an Interceptor missile with Surface to Air Missiles. There is no comparison.
I have very serious reservations in your claim without any link to support it that Prithvis can be kept fueled for upto 10 years thanks to DRDO.
Please provide link to support your claim.
Disadvantages of liquid propellant rockets include requirements for complex storage containers, complex plumbing, precise fuel and oxidizer injection metering, high speed/high capacity pumps, and difficulty in storing fueled rockets.

You do have a comprehension problem!
As you put it Prithvi in this case is is an interceptor which means it takes off from earth and goes in to air and tries to intercept the ballistic missile in the air! So it is essentially a SAM.
And you are showing your ingnorance about SA-5 (was also known as s-200, predecessor to s-300) and A-35! They were Soviet era ABM!
I don't give a rats A$$ about your reservations, or what you believe! Do your research yourself!

I see. So Prithvi is a SAM now that can be kept liquid fueled for 10 years. Interesting.
Why make a claim when you can not support it by links ?

I would suggest that one conduct a little research when disputing statements other forum members make, particularly when details are provided. In this case, articles like this provide some corroborating information about a Prithvi-based interceptor.
Also, please refrain from making baiting or argumentative comments. They add nothing to members' collective knowledge to the level of discussion or debate found on DT.

The debate in question is the claim by Kams that liquid fueled Prithi can be kept fueled and stored for upto 10 years on which I expressed my reservations. (I still stand by them).
One more report where Dr.V.K.Saraswat specially refuted this notion about liquid fuelled Prithvi,
Quote:
Replying to a question on whether there was a refueling problem with the surface-to-air 'Prithvi' missile, he said the Army had been using it since 1994 and was "very happy" with its functional capabilities.
"Pirthvi missile can be fuelled anywhere though it is generally done in depots. But once this missile is fuelled, it has a life of 10 years," he said.
After winding up A P J Abdul Kalam’s integrated missile programme, the Defence Research and Development Organisation (DRDO) has identified five new-age missiles, which will keep the missile scientists busy for the next five years.
The indigenous beyond-visual range air-to-air missile Astra and submarine launch capable K-15, which will complete India’s nuclear triad are the two key missiles in this bouquet.
A long range surface to air missile being developed jointly with Israel for the navy, supersonic cruise version of Brahmos and more than 5000 km range version of Agni are the remaining three which were conceptualised outside the integrated programme, Dr Prahlad, one of the chief controllers at the DRDO said on the sidelines of the ongoing Defexpo-2008 here on Monday.
The much-awaited K-15 that can be launched from an underwater platform is almost ready as DRDO is getting ready for its sixth and possibly last developmental flight. “The test can be done any day in February-March as we are waiting for clearances,” he said.
When ready the 700-km range K-15 will be a part of the indigenous nuclear-submarine being developed by the navy and department of atomic energy. DRDO began developing the K-15 almost 10 years ago.
“The missile is ready for integration. It’s up to the navy to provide the platform. Only they know the timeline for the platform,” Dr Prahlad said. The indigenous nuclear submarine – known as advanced technology – is believed to be ready for trial in 2009.
Long-range missile
The long-range surface to air missile (LR-SAM) for the navy is another missile, which DRDO hopes to complete in the next three years. The missile with 70 km range is being developed jointly with Israel and 30 Indian scientists are working on the project in Israel.
Being created in a Rs 2000 crore project, the Indo-Israeli missile will shoot down maritime aircraft, helicopters and unmanned aerial vehicles.
While India is responsible for developing one stage of the LR-SAM and C4I system – command, control, communication, computing and intelligence – Israel Aerospace Industries will be for the second stage.
The missile will be assembled in India while flight tests would be carried out in both countries before the missile is ready for the navy, Dr Prahlad said ruling out that the missile was a long range version of Barak.
A Rs 1000 crpre project to develop beyond visual range capable Astra with a range of 80 km will take five more years to complete. After testing the individual components, the integrated missile is now being dovetailed with MiG and Jaguar fighters for flight trials, he added.
I am convinced that what you claimed is a " masterpiece " of bad Indian journalism.
I searched everywhere and I have come to the following conclusion that He meant that once fueled, it is only good for ten years after which it will be discarded. Either way. it has to be defueled.
It doesnt say anywhere that it can be stored fueled for upto 10 years.

You are free to draw your own conclusions!
If interested read about thixotropic propellents.

hey guys,great news here,it seems that india has successfully testfired an underwater launched ballistic missile called the k-15 from an underwater pontoon launcher ,this missile is to arm indian nuclear submarines,when they are ready and has a range of about 700 kms.
good news
India successfully test fires K-15 ballistic missile

: India on Tuesday test-fired an indigenously developed nuclear-capable submarine-launched ballistic missile (SLBM) from an undersea location off the Orissa coast, an official source said.
“The missile was launched around 1 pm,” the source said of the sixth test of the 700-km range Sagarika missile.
Since the Indian Navy does not have a submarine capable of firing an SLBM, the test firing was conducted from an underwater launcher positioned 50 metres under the surface of the sea and 8 km off the Orissa coast.
Prahlada, Chief Controller of the Defence Research and Development Organisation (DRDO) that developed Sagarika, said earlier this month it was also readying for a “crucial” test of the missile from a submarine. “We have asked the navy for a submarine to enable us conduct the test,” Prahlada told reporters during the DEFEXPO International Defence Exposition on February 16-19.
However, this could be a while away as Russia is yet to respond to the Indian Navy's request for loaning an Akula-class submarine that is capable of launching SLBMs. The navy's Russian-made Kilo-class submarines and the German-designed HDW submarines do not have the capability to fire such missiles.
The success achieved last year with exo-atmospheric (outside the atmosphere) and endo-atmospheric (within the atmosphere) anti-ballistic missiles, as also with the surface-to-air Akash missile, had apparently encouraged DRDO scientists to test the Sagarika again.
Powered by a turbojet, the missile can carry a 500-kg payload. It is 8.5 metres long and about a metre in diameter.
