Planetary Defence Center/Shore Defence Center Concept

This is a rough idea, so before I go into detail like exact weapons and cost etc. I wanted to know what people think. The PDC concept is easy, create incredibly large concentration of firepower which the only way to easily take out is the use of nuclear munitions. Of course if nuclear munitions are used then it becomes pointless because both side suddenly cease to exist, so simply arguing that they are impratical because of nuclear munitions is pointless.

Essentially a PDC is a massive firebase/airbase/vehicle yard/SAM silo. It has exterior landing runways that connect to ground level interior runways that it turn connect to underground hangers. It would feature 20cm-40cm Breach Loading Mortars and 30cm-80cm howitzers along with several thousand VLS(featuring a tiered system) cells. It would feature an alternating layer steel reinforced concrete then ceramics and DU armor (20m concrete, 1m ceramics/DU) with up to 105m total armor. It would have the ability to house hundreds of Bolos or thousands of conventional tanks, and would be placed near an underground water source.

The essential or delicate structures will be placed on shock absorbing springs, with the computer control center being proof from even shockwaves produced be nuclear weapons. A PDC would feature some of the most powerful PD, more then most super dreadnought battlegroups. It wold feature over 300 individual PD weapons inplacements, including a heavy THEL component. All PD, BL Mortar and howitzers would be retractable and when extended would have armored walls around the emplacement high enough to prevent splash damage from destroying too many emplacements. A PDC would be powered from a deeply buried high wattage nuclear powerplant and include fuel for several decades, it will also include consumables for several months including food, fuel, ammunition and water. The command and living portions of a PDC would be completely sealed from biological and chemical attack.

The PDC would feature the most powerful LADAR and radar arrays of the planet, each of four combined emplacements easily able to see the moon when not below the horizon and has resolution high enough to pick out and target satellites with easy. Each array is centered with a cluster of twenty PD systems with which are specifically tasked to protect the arrays above all else. The PDC can and does accept information from other PDCs and airborne radar etc. so even destroying all four arrays does not blind a PDC.The estimated cost for a PDC is in the hundreds of billions of dollars, even as high as 800 Billion.

An SDC is a PDC without the aircraft and tanks. It features 80cm-120cm ETC guns on the seaward side, also several thousand VLS tubes on top with the assorted PD found on a PDC. Instead of 20cm-40cm BL Mortars the SDC features 40cm-60cm BL mortars, longer ranged and excellent for slaughtering landing infantry. It has removed the howitzer in favor of more PD and an additional two LADAR/radar arrays for increased ability to intercept heavy shells from ships batteries. The SDC has less armament then a PDC, but features better dectection abilites and only 2/3s the cost of a PDC.

OOC: I didn't get any feedback on the NS Draftboard, so I guess that I have graduated to here. Too expensive for smaller nations, but is it a useable idea for the nations with 20+ trillion dollar military budgets?

ooc: What does PDC/SDC stand for, and what about KEW(Kinetic Energy Weapons(think meteor)), how would it stand up to one of those?

OOC: Oops, sorry. I guess I missed the part about names when I copied it.

PDC: Planetary Defence Center
SDC: Shore Defence Center

PDC is rather presumptous because it doesn't actually cover a planatery range, but I like the name PDC. It handles KE fine, after all it has a total of 5m of armor that makes tank stuff look like cardboard and 100m of steel reinforced concrete. If the KE is nuke level then the nuke arguements apply, and where would a MT nation get that big an astroid anyway.

OOC:I call it a big-sitting target for space based Tungsten Rods(AKA: 'Rods of God')/Falling Stars. The former are Kinetic Energy Weapons launched from a sattelite capable of taking out a VERY deep bunker. The latter is... a suicidal sattelite, both use Kinetic Energy to take out their target and can, at the least, cripple these things, at the most blow it skyhigh. Also, multiple Deep-Penetration Bombs(AKA: Bunker Busters) at multiple points threw out the thing would work too.

Never get the satellite over it, I didn't spend trillions on laser armed space stations to let someone put up those type of satellites in my section of sky.

OOC:Kinda hard you know? You see... these sattelites HAVE to go over your nation eventually. And if you shoot them down, your gonna have alot of angry nations going down your throat.

ooc: Eventually, most nations satallites will cross above you're nation, and unless you shoot each one down(A very not good idea) they could still be positioned and dropped down/fire down.

OOC: The armed ones, no, the communications stuff yes. It is rather hard to disguise the Rods of God satellites and the other kind can either be intecepted or impact, not that much difference then a bunker buster munition which these are specifically designed to be armored against that type.

OOC:Would you shoot down the Tungsten Rods/Falling Stars if the nation that belonged said sattelites belonged to was at peace with you?

Not when I'm at peace, because unless they had a whole cluster coming in at the same time over my territory one satellite won't do that much, and the rest will be engaged. The only way I could see firing on someone with whom I'm at peace would be in they sent ten or more of those satellites over my nation at once.

oc: Eventually, most nations satallites will cross above you're nation, and unless you shoot each one down(A very not good idea) they could still be positioned and dropped down/fire down.

Not really, they have to drop straight down or you sacrifice mass and speed for range. If it isn't straight down then you don't get 9.8m/s/s accel and you have to fight gravity instead of being helped by it, and you lose additional mass to friction as well.

OOC:Guess theres a good thing as a surprise attack... not to mention that Falling Stars can also throw themselves into orbiting objects(IE: Debris, other sattelites, your space stations, etc). And if that doesnt work... well my Anti-Missile Sattelite does have a laser that can be used against space objects aswell.

PS:And Falling Stars actually have a BIGGER impact then a Tungsten Rod. Given that a sattelite is bigger and heavier, the KE energy would be sufficient enough.

OOC: And my station has enough ablative/reflective armor to last long enough to blow away your satellite. Plus I don't rely solely of stations, I've satellites too. Anyway, a sneak attack would be useless because I won't let anyone build up the number of satellites overhead nessesary to make it effective. Have we established that I can protect from space now? That more of an effectiveness question, not where it can be built for around the specified price or not.

However they have several hundred times the surface area, meaning that they have greater impact but less penetration.

OOC:Armor in space doesnt matter much when you have a sattelite slamming into you at over 1200 miles per hour... now does it?

PS:A single Tungsten Rod could still easily blow these away.

PSS:Your dead wrong about not being able to disguise a Falling Star as a Commercial Sattelite... Its quite easy considering the sattelite IS the weapon.

PSSS:A couple of well placed bunker busters could take these out... given that they are capable of taking out nuclear missile silos that are meant to withstand a nearby nuclear detonation.

Gah, a Falling Star could attack a space station, but it would do at a fraction of the speed it could attack the ground and be an easy target for counter missiles. Orbital KE weapons derive their power from falling and having an insanely high terminal veloctiy, not powerful rockets.

A nuke silo can withstand nearby blasts because it has no vertical profile, if you're outside the crater radius of a nuke then the overpressure wave and does most of the damage. A silos doors are, at best, 3m of reinforced concrete. Thus a PDC has armor around 1000 times the armor of a missile silo when you include the DU/ceramic armor shells as well.

Planetary Defence Center/Shore Defence Center Concept

OOC: Note to self: Distract big, stupid fortresses while invading from air. Send a few spec Ops teams to take them out from the inside out large enough to start landing via beachhead. Take over Scellian homeworld.

OOC: Homeworld? I'm a country, not a planet or collection thereof.
