X-33 Venture Star Reborn as Space Bomber 193
Julius Su writes: "The LA Times reports that the Pentagon is interested in developing a "space bomber" that could be used to drop bombs on any Earthly target within 90 minutes of takeoff -- from an altitude of 300,000 feet. At this height, bombs don't need explosives to function. Critics worry about the start of a new arms race in space. Not to worry, Pentagon officials say -- the plane would fly in a suborbital path and would only attack Earth targets. The plane itself would be adapted from the X-33 Venture Star, originally developed at the Skunk Works as a vertical-take-off glider-landing reusable space vehicle." NASA needs to simply glue machine guns to every launch vehicle they have to assure permanent funding.

"Arsenal ship was a joint Navy / DARPA program to acquire a moderate cost, high firepower demonstrator ship with low manning as soon as possible. The Arsenal Ship was planned to restore the naval support of the land battle, the modern day equivalent of the firepower that battleships provided during World War II and in Korea. The plan was to produce the demonstrator ship for initial operational capability (IOC) by the year 2000. Based on successful demonstration, a total force of four to six Arsenal ships would be funded. The goal was to develop an Arsenal Ship (AS) functional design by the end of FY97. This timeline from concept design (FY96) through fabrication (FY00) represented half the development time of previous naval vessels of this complexity. The Arsenal Ship would contains four times the VLS cells found on a CG-52 class ship, have a fixed unit sailaway price of $450 million, and a life-cycle cost 50% less than that of a naval combatant."
So for the layman - It was a ship that carried alot of cruise missiles (Tomahawk Land Attack Missile), an advanced gun-system and was mostly below the water line, with only a senor mast and navigation bridge and helipad above water.
"The ship would have the equivalent ordnance--about 500 vertically launched weapons from a wide variety of the military's inventory--of about four or five Aegis cruisers and destroyers. Employing the Cooperative Engagement Capability (CEC) "remote magazine" launch concept, the arsenal ship would provide additional magazine capacity for Theater Ballistic Missile Defense (TBMD) and Air Supremacy missiles.

It would have a crew of roughly fifty and would have been 500-800 feet long.

"The Global Rocket 1 (GR-1) requirement of 1961 called for a system to place a large nuclear warhead equipped with a deorbit rocket stage into a low earth orbit of 150 km altitude. The warhead could approach the United States from any direction, below missile tracking radar, so little warning was available. Not only could such a missile hit any point on earth, but the enemy would also be uncertain when it would be deorbited onto target. The main disadvantage was lower accuracy of the warhead in comparison to an ICBM. "
"Flight trials of the system were conducted 1965 to 1972. Since orbiting of nuclear weapons was a violation of international treaty, the Soviet Union conducted all tests on a 'fractional orbit' basis - i.e. the test warheads were deorbited after less than one orbit of the earth. The system was in service at 18 siloes at Baikonur from 1969 to 1983. "
I count 28 tests from 1961 through 1971.

I would argue that the real reason Germany didn't use it in WWII is they lacked effective countermeasures to protect their own troops and thus its value was much less than its risk. It was this issue that had created problems with the usage of gas from Ypres on in WWI.
With infantry in an explotation role mounted, effective suits for unmounted infantry securing an area, and positive pressure filtering systems on vechiles have made gas much more effective.

Nuclear weapons have to be set off intentionally...you don't just drop it and have it go off like a cheap pistol. Trust me, the US military alone has "tried" this a lot.
In fact, US weapons are specifically designed NOT to do this. The detonating explosives require specific timing to get the correct denisty/surface area ratio to get the uncontrolled chain reaction. The signalling wires are designed so that relatively small errors in the wire length will prevent correct detonation timing. And if it doesn't explode then we have roughly the same dangers as other radioactives going into orbit, which has nothing to do with militarization of space.

Well, a conventional explosive won't do too much. You'll need a lot of them in order to really damage a country's infrastructure, and that takes a lot of time, effort and money (e.g. Gulf War, Bosnia to use US examples). So, you go to nukes. Problem is that there're long-lasting negative effects from nuking (radiation), not just to your target country, but to large portions of the surrounding geography (even the world, of you use enough).
When you're dropping a rock (or car, whatever) from orbit, you have nearly no radiation, and total devistation of the target. So, you can take out N. Korea without any more than kicking up a whole lot of dust at S. Korea. So... why not?! That's the key problem with this kind of weapon: it's a weapon of mass distruction, which cannot distinguish civilians from military targets, and there's very little to hold one back from being the first (an possibly last) to use it....
Second, there's a question of the continued military applications of space. Our population is getting uncontrolably large on this planet, and we may well *need* to start exploring the use of space for: mining, power generation, even manufacture in order to support our population.

v_i = g*t = g*sqrt(2*100000/g) = sqrt(2*100000 * g) (~= 1453 m/s)
No big difference, you'd think. But energy varies as the square of the velocity, so this reduces yeild to (v_i^2/2) Joules per Kg (~ just shy of 1 MegaJoule per kg). This is 1/220 th of your value. Assume we could drop a KiloTonne (assuming metric tonnes: 1 tonne == 1000 Kg), that would give us 1000 Gigajoules, or 1/4 as effective as good old TNT.

Hrm. Is that so? I mean, you can easily calculate the kinetic energy per Kg. What is the terminal velocity of a warhead shaped thingie? A google search for joule kilotonne gives 4200 GigaJoule per kilotonne. The maximum payload of the x33 is 25000 kg, so counting backwards, we see that the payload needs to reach ~ 18300 m/s just to get a kilotonne yeild (and that's for a 40th of a kilotonne, which isn't great). Furthermore, that is mach 61, which I suspect is beyond the terminal velocity of anything in freefall (ie, without incoming velocity).
However, if you want to knock out infrastructure without serious casualties, dropping 25000 unpiloted slugs might do the trick. or 50000 1/2 kilo ones that have explosives. Especially if you can drop them in piloted packages to disperse at lower altitudes. Terminal velocity is your friend, since it basically means you loose nothing by dispersing late (presumably the smaller slugs have higher terminal velocity than the delivery package).
So actually, I see this as a fairly humane rapid suppression device.

Second, even in a completely logical environment, you won't find true multi-lateral treaties observed for very long. The governing logic is Prisoner's Dilemma. There's a lot of research that shows that in a 2-person (aka bilateral) PD environment, cooperation is very common, because it's in both sides best interests. In a multilateral PD environment (3 or more actors), however, cooperation quickly breaks down, because even though cooperation is in their _collective_ best interest, it is not in any _individual's_ best interest. I did some research on this in the early 90s as it applied to arms control treaties, and verified that that was in fact the case - one look at the power structure involved in the treaty, and you could tell if it was going to work.
In sum, the 1967 treaty was perfectly workable as long as there were two opposing power blocs - neither side wanted the other to militarize space, so they were willing to forgo the benefits of doing so in return for the benefits of the other side NOT doing so. Once we moved to a multilateral world, however, all that logic fell by the wayside.

War is like that - people make choices. Sometimes they're right, sometimes they're wrong. In those two cases, people didn't die due to lack of preparedness. They died because of poor decisions.
Preparedness, though, is having orders out/construction started/mobilization begun for most of the equipment used in the war, in 1940. Do you realize that most of the prototype work for the equipment the US Army took into battle _through 1943_ was done before 1939, before the war ever started? The US Army went into WW2 with _buildings_ full of detailed industrial mobilization plans. The US Navy wasn't far behind, either. All of the aircraft that won WW2 were designed and in production (LRIP, at least) prior to Sept. 1941.

King is still dammed, 6 months to admit a mistake that occurred, solely by his personality flaw. Admiral Sims during World war One recognised the threat of U-Boats and convoys as the only means to counter them, he advocated that to the British in 1917.
Well, to give the man his due, he had a few other things on his mind at the time. The folks I'd really go after are the leadership for the Atlantic and Home fleets - they're the ones who really botched up the convoy protection issue. A lot of people in the US didn't think the war would reach all the way across the Atlantic, though - they were quite surprised by the method of the US entry into the war, and by some of the immediate consequences. You might note how unprepared the French were, _6 months_ after they entered the war.
Read John Terraine's "Business in Great Waters, The U-Boat Wars of 1915-1945". It is the definitive book and damms King and the Navy (and in fairness, the British Navy in early World war Two gets dammed as well).

Always the case, unfortunately.
The first Zero, was captured in February 1942 and shipped to the US for evaluation. It crashlanded almost intact on Thursday Island off the north coast of Australia, following a bombing raid on Darwin (Feb 23 or 29th, 1942). It is easy to see why it has been overlooked historically, US forces didn't capture it, so it has quietly been forgotten. That Zero was used in the designing the Hellcat.
Interesting - I hadn't run into a reference to that one. Date was actually Feb. 19, 1942. Based on the condition of the plane (see the pictures at http://www.fortunecity.com/meltingpot/statuepark/6 20/toyoshima.htm), it looks like it wasn't in flyable shape, so they probably disassembled it and looked it over. The 8/42 Alaska capture was the first one in flyable condition, so it's still arguable, a bit. I wouldn't be surprised if you're right, though, that some elements of the Zero design wound up in the Hellcat.
The Mustang is fascinating, it is the supreme piston engined aircraft of World War 2, but my point was, it was not designed as a long range fighter pre war, so no credit can be taken for it. It evolved almost accidently.
Umm, take that further. It wasn't designed prewar, _period_. North American didn't even start talking about a design for such a plane until mid 1940. The original design, with the Allison engine, was built as a low-level fighter - everyone knew the supercharged Allison wouldn't put out the horsepower needed above 15K feet. Don't know who had the idea to put the Merlin in, but all the design folks knew that would resolve the high-altitude performance issue. A couple other interesting points to note. First, the A-36 was designated as a dive bomber to sneak it into the US inventory. It was, in fact, a fighter from the get-go. Second, The P-51 is pretty much a descendant of the P-40. The North American NA-73 design was, it turns out, partially based on a Curtis-designed successor to the P-40.
Indeed the USAAAF prewar advocated the dogma of the self protecting bomber ie the B17. That dogma was persisted with despite its known fallacy, the ultimate dream was for an independent Airforce and bombing was the way the advocates saw to achieving it. The tradegy was in the pursuit of that dream, the planners condemmed thousands of young men to death, the lessons of the Britsh and the Germans were there, but ignored. Not until the second Schweinfurt did the USAAAF accept that their prewar plans were fantasy.
_Every_ prewar bomber command advocated large bomber strikes. The USAAF was simply the last to have the blinders taken from their eyes. To some extent, they had viable reasons for believing as they did. 1943 really was educational, though, in that it demonstrated the big logical fallacies that couldn't be ignored. BTW-- you might note that by Feb 1944, the bombers were essentially being used as bait, to bring up (and kill) German fighters, in preparation for the June landings.
As an aside the tactic used effectively by the Luftwaffe with head on attacks which rendered the B17's almost defenceless (till the G model) was copied from the RAF No. 111 Squadron, they first used it in the Battle of Britian to attack the German formations. Again a lesson was clearly there but ignored, the question is with almost 3 years to do something(1940-1943), that design flaw in the B17 should have been removed before crews were sent into combat.
There's endless points like that. Did you know that the primary reason the US forces went ashore with Shermans in June of 44 was because George S. Patton thought bigger tanks like the M-26 would be less maneuverable? Turns out that the M-4 had _higher_ ground pressure than the M-26, and was thus less maneuverable on rough ground. But the decision had been made in Jan. 1944, for delivery for the June landings. Once the production targets were changed (7/44), it took another 5 months for the M-26s to get into combat.
As for the Mosquito, it is an anomaly, so clearly superior to any other bomber be it British or American, fast, cheap to make, to maintain, less expensive in crews to train and man, the lists goes on and on.
Hmmm. Semi-arguable - the A-26 Invader had an illustrious post-war career (into the 70s, actually) for precisely those same reasons. But when it debuted, it definitely set the standard.
Were the lumbering fleets of four engined heavies necessary militarily or merely politically, Generals needs armies, without them their prestige is lessened.
Iffy, either way. Once the war started, everyone pretty much had to start building what they had available. B-17s, for example, were produced because they were what was available. Same with the F-4F and P-40. Hell, why do you think there were P-39s/400s sent to Guadalcanal? They were the _wrong_ plane for the mission, but they were also the only thing in the bucket to send. A lot of what was done, was theoretical, with very little way to check accurate results. So everybody tried out their ideas, to see what would work. Ploesti, for example, demonstrated that mass, low-level bombing was suicide. Yet Wewak showed that low-level tactical strikes _did_ have their place. The whole air-support campaign in the Solomons Slot, as well as the Battle of the Bismark Sea, showed what land-based air could do to naval forces, given the chance.
It's still true, though. Take the US Marines. Most of the amphibious doctrine that they used in the Pacific was written and tested in the 1920s. Their close-air-support doctrine was forged in Nicaragua and Haiti, also in the interwar period. Or, use the US Army. All of the tactical infantry doctrine was worked out in the 1920s and 1930s at Ft. Benning. Most of their counter-Panzer doctrine was developed in 1940, during things like the Louisiana exercises (I can't stress it enough - go read Perret on this - he says it far better than I can). Or, the US Navy. Carrier doctrine (as well as unrep capabilities, which were _just_ as important) was worked out in exercises during the 1920s and 1930s. Every major (and most minor) combatant design that the US Navy brought to the party was worked out and ready for production (if not already IN production) before 1939, and they were _all_ on the order books in the 1940/41 budgets. I can't accept your comments about poor decisons of King and Macarthur, they still equate to me to a lack of planning and taking Dixon's book in account shows a serious flaw in the military. Both men's command clearly failed when tested in battle. The mistake they both made was their egos could not accept they could learn from others, King from the detested Britsh and Macarthur from the enemy.
Well, that's an opinion thing. IMHO, Macarthur and King were well prepared, and had planned in-depth for the coming war. However, I think it would be an accurate thing to say that their plans were not necessarily the correct ones, and that they perhaps planned for the wrong war at times. Macarthur pretty much threw away the Phillipines, because (a) he and the War Dept. planned to fight different wars, and (b) once the shooting (and the landings) started, he didn't fight the war he planned for anyway. A great example is the huge supply caches he built up on the central plains south of Manila. After setting his supplies out front, so he could execute a fighting withdrawal, he wound up boxing himself into Bataan, and left large supply caches out for the Japanese to capture. King, similarly, didn't plan for the kind of war the Germans decided to fight - he was thinking offensive strategies in the Atlantic, and then had to strip _that_ capability to cover for the carnage in the Pacific.

One of the interesting issues exposed by the Gulf War was that, given the then-current state of the art, a given firing ship could actually control a lot more firing tubes than were mounted on it. For example, an Aegis cruiser could comfortably target/control several hundred SLCMs, but only had about 70 tubes, and usually kept >2/3 of those filled with SAMs for self defense. Since the control electronics were the expensive part of the equation, and since a properly equiped ship could easily control other ships' missiles, some blithering idiot put these facts together and came up with the arsenal ship.
The basic idea was to have a (large) ship, built to civilian standards (not military/blast/etc. resistant), with a small crew (40ish, as I recall), and only minimal self-defense capability. The ship's primary purpose was to be a great, big, floating VLS platform - the design I saw had over 200 VLS launch tubes, which were to be filled with cruise missiles, with a few SAMs thrown in for use by the accompanying warships if needed. No control electronics, except those needed to permit another ship to control launches, would be included, however. Plans were to build 2 of them - one for the Atlantic fleet, one for the Pacific fleet.
The idea ran into several practical problems:

Personally, because of this aspect alone, I think the whole thing is a good idea. Other people posted that once we have the first space-based (sub-orbital or not) weapon we're going to have to develop more weapons (in space) to combat other people's weapons (in space). Think Fighters/Bombers.
I've recently read a few good books about the Gemini and Apollo era of space exploration, and the one common theory I've seen in all of the books is, "America needs an idea or threat to organize around- like the Manhattan Project or the Apollo Progam- to do anything of significant import to great ideals." (Not having to do with their immediate lives).
What this means, is if our population is suddenly worried about what type of missle carrying satellite China just sent up the population will support weapons reasearch and deployment. NASA had a budget of 5,000,000,000 during the height of Apollo because the public cared. If it does again more advances in space will be made.
Also, the ramifications of this would not only affect the military, because space, at the moment, is only NASA's domain. If the Air Force or whomever wants to launch missiles (heavy payload) they're probably going to need NASA's help. This means NASA gets money to research rockets, launching platforms, and whatnot. Every advance made for the military also helps the exploration of space in general.

Something that might be useful would be depleted uranium encased in such a ceramic as a penetrator. It makes a nice penetrator not so much for its high density, but more for two other characteristics. The first of these are uranium is self sharpening. Instead of blunting, as it penetrates, the burs which are certain to form, and might blunt the point would instead peel back revealing an eversharp tip. The second quality of interest is it happens to be pyrophoric. While the penetrator itself might not detonate, the peices of metal that spall off it will be exceptionally hot and pretty well insure that such a penetrator incinerates anything living or useful. In this instance, the high density of the uranium would also serve to enhance the velocity of the penetrator, as the terminal velocity of an object is determined primarily by its density and surface area.
But a full on weapon that is designed to be lauched from a platform as ludicriously expensive as the one proposed would not likely be simple and cheap. One might certainly envision a large guided weapon with multiple warhead consisting of penetrators with explosives sitting at the front of a decent sized rocket. This weapon might glide to a few tens of thousands of feet above its target, them turn on its rocket for an extraboost before launching the warhead, which might scatter the individual penetrators just before impact. Or it may simply just be a warhead large, heavy and fast enough to dig down to and shatter any bunker.

Good calculations, but that's not the problem in your thinking. The problem lies in the fact that terminal velocity doesn't entirly apply to this scenereo. Terminal velocity keeps an object from accelerating beyond it within the atmosphere with only the earth's gravity to accelerate it. Unfortunatly, terminal velocity does not apply without the braking effect of the atmosphere acting on it. That is why meteors fall at very very high (read: much faster than terminal velocity) speeds. If something could only fall at terminal velocity , nothing would ever burn up in the atmosphere. In other words, with these theoretical explosivless bombs, all of there acceleration is done OUTSIDE the atmosphere, and hence they are able to accelerate to much greater speeds before the atmosphere acts on them. And even once they do impact the atmosphere, they will already be going so fast that the braking effect is negligable. Like a speeding frieght train hitting a tractor-trailor. Sure it will slow down, but it's still quite deadly. So yes, it is so. With enough force coming down on something, you won't just punch a hole in it, you'll obliterate it. Think of this, not as a bomb, but as a man made meteor. Yes, terminal velocity would kick in EVENTUALLY, but these bombs would have to be quite lite for them to decelerate to terminal velocity before they reached the ground. Okay, so now you've piqued my curiosity for the actual numbers...
The Meteor example I pointed out before is probably a bad example for our purposes, because those meteors don't (all) just rely on the earth's gravity for acceleration. Most already have a relative speed of many thousands of miles per hour before they ever get near the earth's gravity well.
Now, the article said that the bomber would be capable of delivering strikes from 60 miles+ let's just round that to 5000 ft per mile 5000 * 60 = 300,000 ft. Now let's round this again to 100,000 meters. I know it's not exact, but bear with me...
Now with an altitude of 100,000 meters, we simply use 9.8m/s^2 as our acceleration rate. This will give us a speed of 2243 meters per second at 0 feet. Keep in mind that this formula does not account for friction of the atmosphere. Now let's figure out how much force we're going to deliver, okay? The military uses 500 and 1000 lb bombs a s a sort of standard. These labels are for the entire bomb, not just the explosives. Typically half of that weight is explosives... So let's assume that they'll continue to use these denominations. Let's even go with the lighter one to support your argument. Now 500 Lbs is 227.27 Kgs Let's again round down to 225.
Now, let's recap:
We have our theoretical (frictionless) impact velocity:
2243 m/s
We have our mass:
225 Kgs
We have our altitude:
100,000 m
Now to calculate energy we use the formula:
mass * g * altitude where g = 9.8m/s^2
Using this we get:
220,500,000 joules, which according to your formula of 4200 Gigajoules per kilotonne is 0.0525 kilotonnes. Not much when you're thinking of things in nuclear proportions, but that is a hell of a lot when you consider that his is a single 500 pound bomb without a warhead.
Just for referance, the Hiroshima bomb had a yield of 20 kilotonnes.
Okay, by now half of you are thinking to yourselves that that's a big yield for a "conventional" weapon. And I'm sure a lot of you are still scratching your heads and saying "well what about the drag?" That's where Jovlinger is right. There *will* be drag acting upon the missile-meteor. Not only will it slow it down, but it is likley to reduce the mass of the bomb too, due to much of it's mass burning up on reentry. The only site I was able to find that deals at all with both of these paramaters (mass lost and drag that varies with variable atmospheric density) is here [gmu.edu] The test at the botom of the page is the most relavent one since it uses a 90 degree entry angle. However it is only a 100kg model. Even still, 66% of it's mass survives reentry and it impacts with 795 kilojoules... Keep in mind this is less than half of our theoretical meteor-missile. Now, what does all this mean? I havn't the foggiest idea. Is this weapon anywhere nuclear class? No. But these numbers, I believe are quite respectable for conventional weapons. By the way, if none of this makes any sence to you, it's probably because I havn't slept in 36 hours, so if someone wants to try and translate this post into something more human readable, be my guest ( :

The Pentagon has long talked about a Space Plane project. As it is, this is a bad program. The X-33 has technical issues, but I'm sure they will be worked out. On the other hand, it's heavy, relatively fuel-inefficient (for example, the failure of honeycomb design fuel tanks - and replacement with conventional ones - has resulted in significant weight gain/total fuel loss). It also wastes a HUGE amount of infrastucture on carrying a human crew - the same problem exhibited in other Air Force projects. Make something like this unmanned and you can halve the weight, greatly reduce development costs, and make running costs significantly lower - not to mention you don't have to worry so much about pilot safety.
This program satisfies several of these objectives. It further militarises space, gives the Pentagon a shiny new weapon, and gives Frank Gaffney reason to send more faxes to anyone and everyone. In reality, it will be like the B2; expensive, capable of hitting a small number of targets per trip (with high turnaround times, to boot). It's unlikely that very many will be built, and the X33 program already has significant cost overruns. Just like the B2, it will be dubbed as "equivalent to X conventional planes" (with X being a large number) despite the fact that you still need the other X-1 planes for more general purpose missions. Rumsfield is proving to be like Weinberger; willing to spend big bucks on technology that the services want without trying to fit it into any sort of grand strategy.

The bombing mission profile doesn't make any sense either. If the costs of launching this thing are anything like the Space Shuttle than the missiles are cheaper. (and faster, at least with regard to ICBMs) Since the US refuses to learn from Russia and develop economies of scale in rocket production, the military would seem to be the perfect place to do it. The missiles would also be unmanned (much better for PR), and could draw on a much better set of guidance technologies than the kinetic weapons to be dropped from this thing. I think that the problem of targeting these things may turn out to be fatal. During reentry it can't communicate via radio (no GPS) and unlike an ICBM it doesn't have a miss radius. (It has to hit the target dead-on, it can't miss by a mile or two) Cruise missiles may actually be more viable, as only really the Great Powers poisess the technology to stop them and they don't have guidance problems as severe. They also don't generate US casualties.
This project is also indicative of the breakdown in US war planning. In an actual, all-out war, this thing is useless. It doesn't have nearly enoigh payload and costs far too much.

However, you can check that for yourself: Suspend a penny from a thin string and dangle it out of the window of your car (driven by a friend, of course).
While you pick up speed, the air-drag will increase the angle of the suspending string to the normal (vertical). When this angle reaches 45 degrees, the air-drag is just as big as the gravitational force exerted on the penny. The speed you then read on your odometer is the maximum speed a free-falling penny could attain.
If this speed were 20m/s, then it would be attained after the penny fell from a height of app 20m (65 feet), disregarding air-resistance during this first 2 seconds of acceleration.
In practice, it will not make a noticable difference to the speed of the penny if it was released from 100 feet or 1000 feet. If released from space, from any height or at any initial speed, it would either burn up completely, or be checked to just that 45mpH before reaching the surface of the earth.
If you throw out a penny at 45mph from the window of your car, or release it from the 6th floor of a building, it will not create an impression I would care to call a crater.
