The Case for the Space Force

Can Co-orbital ASAT be used for BMD applications?

Ya'll Nibbiars yeah see the Brilliant Pebble's.

 

[Vamsi]

Yeah I knew about that. But it was too costly at that point of time ? Is it economical to have that kind of system in todays scenario?

Ya'll Nibbiars with the Launch vehicles cost have been reduced. And the RLV.

 

[Haldilal]

Ya'll Nibbiars the Independent Space Force would be the Smallest and the Least staffed service. The budget could be anywhere between 1 to 2 billion dollars and staff between 6,000 to 10,000. Including the civilian staff. And the most less beaurecratic service. The equivalent of the ISRO.

 

[Haldilal]

Ya'll Nibbiars You invite conflict when there's weakness, and I believe you deter conflict when there is strength, and that is the path we're on. Taking this approach will lead us to a more strategically stable situation that deters conflict in space.

The issue of the privately owned satellites is also there the issue of security for these private or science-focused satellites. "Do they want to be protected or escorted?, comparing these craft to private ships that were escorted in convoys during World War I to keep them safe from enemy attack from newly introduced submarines.

The proliferation in low Earth orbit of commercial satellites, in some ways, might be the greatest threat to space sustainability, adding that this will only really be a threat if not done properly.

Ya'll Nibbiars ever hard of the Sea Dragon?. Electric Nuclear Drive Propulsion?.

Ya'll Nibbiars ever hard of the Sea Dragon?. Electric Nuclear Drive Propulsion?.

No,what is it? Is it Mlecchas tech?

 

[Haldilal]

No,what is it? Is it Mlecchas tech?

Ya'll Nibbiars it's a concept of LV of 150 meter tall and 30 meters width capable of putting 550 tons of payload in the LEO at a 600 km orbit.

 

[Haldilal]

Ya'll Nibbiars I clearly remember there was now talk if India can build a similar concept back. If ever made will reduce the cost almost many times and after its easy to build like in a ship yard with inexpensive materials and a simple but large Pressure-fed engine a well like a Big dumb booster. May be great for military space missions.

Is it what you are talking about? Its our manned moon mission plan released in 2009

Ya'll Nibbiars na on a much larger scale like 10 to 20 times larger.

Ya'll Nibbiars India's launch capabilities are constrained by its geography. While the US is blessed with the very wide Atlantic Ocean to launch across, India is currently limited to launching across the Bay of Bengal which is much less wide. This imposes a cap on delta-V for the lower stages, to avoid having anything fall on Indonesia. Furthermore, other compromises like a dog-leg maneuver are required to avoid overflying Sri Lanka, which also affects performance.

But a Sea Dragon concept would be much more portable, and could be launched from farther down in the Indian Ocean proper, even by the equator. As with BFR, launching out at sea could spare local inhabitants from disturbance, which would be of greater concern for a much larger rocket.

The Sea Dragon was notably designed to be constructed from cheaper materials such as steel plating, which might be easier for India to work with, leveraging lower cost of production. Spec'd to loft a whopping 550 tons to LEO, the very huge Sea Dragon was to use a lower stage propellant supply of RP-1/LOX, while its upper stage would be LH2/LOX. The rocket design did not require a turbopump, but would instead use simple pressure-feed from compressed nitrogen.

The LH2/LOX was to be generated prior to launch from a nuclear-powered support vessel, like a naval aircraft carrier, via electrolysis of seawater. India currently has one indigenous nuclear-powered submarine, and operates another leased from Russia. But there are also projects like the Compact High Temperature Reactor currently under development, which could likewise potentially provide mobile on-site power generation out at sea.

Count be great for super heavy military cargos.

 

[Haldilal]

Ya'll Nibbiars I think it was really just the first stage which had the possibility of being reusable. But, what if that entire upper stage could be turned into a large orbiting station/module? Then that kind of makes expendability a moot point.

When such a large object can be sent to orbit, why not keep it there to continue making use of it, rather than wanting to bring it back down? Especially if it could be made refuelable and restartable. I'd read there were ideas for using Space Shuttle fuel tanks in orbit, since they'd already achieved a sizeable fraction of orbital velocity.

It makes me think about what might have been. Suppose India had tried to develop a Big Dumb Booster immediately after operationalizing PSLV in 1994? The simplicity of the system could have meant a faster pace of development. The challenge of producing large quantities of fuel economically for a Big Dumb Booster would have been of a lesser order than in designing a more sophisticated rocket like the GSLV.

Ya'll Nibbiars If someone can get the mega mono chamber engine to work. A modernized Sea Dragon design could toss up quite a bit more than 550 tonnes to LEO. Will make a great tanker to filled up orbital propellant depots. And could lift an entire deep space mission or a entire space station with this.

I think its better to focus on AVATAR like space vehicles.

 

[Haldilal]

Ya'll Nibbiars after The LAC incidents The Military requested additional 6 High resolution Satellite but it's still in approval stage and that's why you need a dedicated Space Force.

 

[Pig benis on sushy]

Ya'll Nibbiars there is currently the Defence Space Agency and other similar organizations but what now needed is a full fledged space force yes it will cost more and will increase the already stressed burden on the small defence budget but either create a new agency to better handle the space asset or lose. The Chinese already has a Cyber and Space Command and the Russian are giving more priority to the Space Command. We need a full fledged space force of equal if not greater budget than the ISRO.

The USSF and NRO has a combined 130 plus satellites and plus other launch programmes in development. Can't really one the DSA and ISRO. Need a full Fledge Service.

Bro it's straight out of context see the current situation- gdp ,defence budget we currently can't replace insas rifle fly old MiG-21 and you are talking space force that's not possible now we don't have the mindset and budget like America and Pakistan jf17 .

 

[Haldilal]

Ya'll Nibbiars And Of the 900+ operational satellites, there are 320 dual use or dedicated military satellite in the sky, half of which are owned by USA alone, followed by Russia, China and India (14) as of 24 January 2018. All these Indian satellites are placed in polar sun-synchronous orbit and provide data in a variety of spatial, spectral and temporal resolutions. Though most are not meant to be dedicated military satellites, some have a spatial resolution of 1 metre or below which can be also used for military applications. And that means our Spacs Miliatry Infrastructure is extremely poor.

Ya'll Nibbiars we don't need that much budget like the USSF and the procument of the INSAS replacment is other matter not just budgetary. And we can start with just a budget as much as the ISRO with is possible to allot with a little increase Defence budget. And the Implications would be much higher's.
