SpaceX's First Military Contracts: One-Hour Cargo Deliveries By Rocket and Missile-Tracking Satellites (vice.com) 101

"The Pentagon is contracting Elon Musk's SpaceX to develop rockets that can deliver packages anywhere on the planet in under an hour," reports Vice: One of the things that makes the U.S. military a dominant global fighting force is its ability to move troops, weapons, and supplies quickly to where they're needed. C-17 transport planes soar across the globe delivering troops and weapons where they're needed. But America isn't making any more C-17s, so while demand for logistics in the military is up, the supply of vehicles designed to carry stuff around the planet is down. To fill the logistical gap, U.S. Transportation Command (USTRANSCOM) wants SpaceX to build rockets it can quickly fire around the globe...

The project is in the early stages and there's no telling when, or if, SpaceX will be able to move MRAPs, guns, and MREs from Fort Bragg to Djibouti in 45 minutes.

Earlier this week, the Pentagon also announced a $149 million contract with SpaceX to build four missile-tracking satellites, Vice reported: SpaceX will build and deliver four of its Starlink satellites which the Pentagon said it will fit with special sensors to allow them to track missiles, including nuke-bearing Intercontinental Ballistic Missiles and hypersonic glide vehicles....

SpaceX's four tracking satellites are a small part of a larger Pentagon plan to put hundreds of satellites in orbit over the next few years. The next layer of the system is slated for 2024 and will include several hundred more satellites in the transport layer and dozens more in the tracking layer, according to the Pentagon...

This is SpaceX's first military contract.

    That sound like a great idea!

    Delivering supplies via ICBM! Now, to the enemy, every supply delivery will look like a nuclear strike, with only minutes left for the decision to launch the counter-attack.

    • The trajectory would be different from an ICBM.

      Besides, I don't think Djibouti will launch much of a counterstrike.

      But I am not sure they have thought this through. Instead of transferring MREs to Djibouti with a sub-orbital space plane, it may be more sensible to just rent a warehouse near the wharf in Balbala and pre-stage a few dozen pallets of MREs there. A quick Google search indicates that warehouse space in Djibouti is very reasonably priced.

      • I think Djibouti was just an example. What if we're sending supplies to the Middle East? Trigger happy Iran isn't very far from Iraq, Turkey, Afghanistan, or Qatar where we might be sending stuff. Anyway, we definitely need this capability and it will help fund SpaceX's starship development .. I assume the same rocket engine (Raptor) would be on Starship as this transporter.

        • Heck, I assume this transporter would *be* a Starship. Musk has already indicated on several occasions that he plans to use the Starship for suborbital passenger flights. Seems to me this is likely the military helping out in funding the development that's already happening, presumably in exchange for SpaceX developing a Starship variant that's more tailored to the military's cargo requirements.

          The US military has supplies in places all over the globe. Please explain why there's this sudden need for one hour delivery when there never has been before...especially when the number of combat troops overseas is down. Also, the article's basic premise that because we're no longer producing more C17s, the need is up and supply down, is patently illogical. There is no increase in need, and no reduction in supply.

          • by Shotgun ( 30919 )

            And the idea that you're going to replace the role of one of the largest cargo planes in the world with rocket is a little ridiculous. The number of rockets needed would be staggering.

            • The rockets will be highly reusable though. They will have enough fuel to fly there and back.

            • And the idea that you're going to replace the role of one of the largest cargo planes in the world with rocket is a little ridiculous. The number of rockets needed would be staggering.

              Maximum payload capacity of the C-17 is 170,900 pounds (77,519 kilograms).
              Designed payload capacity of the SpaceX Starship rocket is 100,000 kilograms.

              You count funny.

          • There is no increase in need, and no reduction in supply.

            There is always a decrease in supply. Those planes are aging, requiring more and more maintenance, spending longer and longer amounts of time in a hangar out of service. Entropy always wins. Eventually every plane stops flying as metal fatigue takes its toll. The US military is known for rebuilding whole planes and calling it "maintenance" just because of Congressional nonsense with funding, but there are limits to that. Eventually the airframe goes out of service permanently. C-17s are no exception.

      • Well depends. American weapons industry wants to maximize.? their profits. That means they *have* to sell to Djibouti e way.or another some day. :)
        Just like they sold to Iran, then Iraq, then the Taliban, then the IS. Gotta have a reason to arm your own boys, you know? :D
        If only the stupid Russians and French and German and Brits wouldn't try the same thing all the time!

        Djibouti would just be a test, they really intend this for use in places where they otherwise couldn't deliver material. In those places and in times of crisis there is a very real danger of someone getting spooked by what looks like an incoming ICBM.

        The other danger is that other countries decide this is a good idea and develop their own systems, and then everyone gets paranoid that one day they might stick a warhead on it or "accidentally" "crash land" on some coincidentally valuable target.

        • One would assume the trajectory is pretty significantly different than an ICBMs...
          An ICBM arc gives the reentry vehicle a fucking stupid amount of velocity. I suspect this looks more like an orbital trajectory that de-orbits at the target. That won't be mistaken for a missile. And if someone puts a missile on such a vehicle, they've just started the fucking nukes-in-space-race.
      • >The trajectory would be different from an ICBM.

        I don't think so. There's exactly one suborbital trajectory from A to B. Prior to reentry, every suborbital flight between those points will look pretty close to identical, though acceleration profiles may be different.

        Now, as soon as it hits the atmosphere a cargo flight is going to change trajectory as it aerobrakes to shed speed, but that doesn't begin until the last few minutes of the flight. And of course there's no particular reason you couldn't lo

        • >The trajectory would be different from an ICBM.

          Wait, no, I think you're right - there's exactly one shortest suborbital *flight time* between A and B, but the flight path can go from a shallow optimal arc, to a much higher arc, which I think takes a lot more fuel, and as long or longer flight time, but can result in a much higher reentry speed, which may be desirable for avoiding missile defenses.

          And of course if you're at war with someone they're likely to want to shoot down your rocket regardless of w

            Bingo. You got it this time.

            And of course if you're at war with someone they're likely to want to shoot down your rocket regardless of whether it's cargo or a warhead, so trying to disguise the one as the other probably isn't worth much - except I suppose for first-strike sneak attacks.

            Again, correct.
            The Soviets experimented with FOBS in the 60s, which offered the benefits of this hypothetical system used as a nuclear delivery platform.
            The ultimate conclusion by the Americans was- sure it's a valid first strike platform, but it sucks at delivery, and submarines are a lot better. So we didn't make one. The Soviets later decommissioned theirs once their submarine force didn't suck.

        • There's exactly one suborbital trajectory from A to B.

          Not true. There are many trajectories from A to B, depending on both velocity and angle.

          ICBMs choose a trajectory to minimize flight time.

          This cargo rocket would use a different trajectory to minimize terminal velocity.

          • If by "flight time" you mean "time in the atmosphere" then that makes sense. For a suborbital, pseudo-ballistic (since virtually all the acceleration is at the beginning of the flight) trajectory though, the faster you go, the further you go (either horizontally or vertically), and the longer the trip takes. The minimum-energy, minimum reentry-speed trajectory is also the one that takes the shortest time to get from A to B.

            Of course I'm assuming ICBMs follow a pseudo-ballistic trajectory. If they instead

      • Not sure if you'd want to stash billions worth of military equipment in warehouses all over the world just in case you need it somewhere sometime. I highly doubt this would be a good business case versus suborbital transport if you factor in possible loss of equipment (due to, you know, someone stealing it) and the massive amounts of redundant equipment you'd need.
      • The trajectory would be different from an ICBM.

        If that's true (which I doubt, but let's run with it) then it's just as easy to sneak a nuclear warhead in as well. Think about that... the safety of the world depends on it being true.

    • And intercontinental bombers looked exactly like airliners and vice versa. This is nothing new.

This is serious problem, and people who say "it's just like a long distance jet flight" are completely wrong, because with an aircraft you have time to send up your quick-reaction fighters to intercept it. With an incoming ballistic package, you don't have a lot of time to react and your only possible reactions are "do nothing" or "launch retaliatory strike".

          With MIRV even one or two missiles can cripple a country with a surprise attack. With mobile and submarine launchers it could be very difficult to determine who they belong to in those first critical hours.

        I think you're grinding an ax instead of using your brain.

        This thing isn't flying on a ballistic trajectory.
        The angle and velocity at which a ballistic RV with intercontinental range falls back into the atmosphere are not remotely survivable for anything with any amount of fragility whatsoever.
        This means whatever trajectory they end up using will not appear anything like a ballistic missile to adversaries with the radar tracking to even watch for such things.

          None of which matters. Why do you think other countries get nervous when North Korea launches a civilian satellite into an orbit that goes nowhere near them? It's because that technology can be used to deliver nuclear warheads too.

            I don't think anyone is worried about what *our* capabilities are, as we can deliver ICBMs with no problem.

      The one hour timeframe certainly does sound like a ballistic sub-orbital flight.

      But you need a solid-rocket to achieve that, as liquid-fuelled rockets like falcon-9 or starship take hours to prepare for launch.

      If they can stretch the requirements to a flight of 2-3 hours (after loading propellant), then a more practical rocket-plane like the X-15 or Hypersoar fits the bill.
      https://fas.org/man/dod-101/sy... [fas.org]

      HyperSoar could fly at approximately 6,700 mph (Mach 10), while carrying roughly twice the payload of subsonic aircraft of the same takeoff weight.

      That is from last century, so not a new idea.
      I'm sure SpaceX would love to get some military funding

      • Beyond the rocket requirements- you aren't shipping anything that you want to survive the trip on a ballistic trajectory at intercontinental distances. Not without significant fuel to slow down or change trajectory before you slam into the atmosphere.
        ICBM RVs have very specific survival requirements. They're built to withstand the 60Gs of acceleration that comes with slamming into the atmosphere from 2000km parabolic arc.

        Terminal phase for an ICBM is like a minute. You don't shave off 6-8km/s of velocity

          you aren't shipping anything that you want to survive the trip on a ballistic trajectory at intercontinental distances.

          If my memory of high-school physics is correct, a ballistic arc can be lower, and do a shallower reentry, like a space shuttle (which was, after all, mostly ballistic), but that requires a greater launch velocity than a regular ICBM, close to orbital. So skipping off the atmosphere like an X-15 is really the way to go.

            Yes- these are called depressed trajectories.
            They're still massively steeper than your example shuttle orbiter reentry, which has a gamma of around -1 degrees, as opposed to a depressed trajectory ballistic missile with between -5 and -10 degrees.
            Orbiters are aerobraking for atmospheric reinsertion- which is our primary problem with trying to make a ballistic missile with *that* flat of a trajectory: It will spend so much time in the atmosphere, that you may as well have made a hypersonic glide vehicle.

        Falcon 9 specifically takes just 45 minutes to load propellant. Rolling it out from the hangar and erecting it takes maybe 15 minutes, maybe a few more. Mating a payload takes some time, but presumably the US military would pay for dress rehearsals to reduce loading time.

        Starship propellant loading times are entirely unknown right now, since the vehicle changes on a daily basis, but Elon Musk has repeatedly stated he wants aircraft-type turnarounds, so presumably they're designing fueling ports and plumbi

        Also, I don't trust the DPRK to reliably distinguish between a US first strike against them vs. a supply delivery during a US exercise right at the border of the DPRK.

    • The stupid thing is the "minutes left" scenario is entirely artificial. That only applies to nukes in silos. The ones on subs and planes don't have that restriction. This is actually a perfect reason to get rid of "use them or lose them" nukes in silos altogether. Then this need for a quick decision goes away entirely and the entire human race is literally orders of magnitude safer.

          I have no problem with a defense budget. The problem is that the US Defense budget is dwarfed by it's Offense budget.

          So you have a (legitimate!) beef with the way the country uses its military might (though I'll note that your distinction between defense and offense budgets is spurious; the tools of the military for both defense and offense are the same). Doesn't it seem like this should be an issue that you address through your elected representatives, rat

    There are some interesting challenges involved in this particular idea...

    First, it might be worth pointing out that whilst SpaceX have a lot of experience of developing re-usable rockets, their current F9 model - and the Falcon Heavy is essentially three F9s for the purposes of this discussion - typically only landsthe first stage, without the second stage still attached - and certainly without the payload still attached. Given the difficulty of getting in to orbit, it is highly unlikely that the current F9 first stage is structurally strong enough to land with a full-weight payload still attached. So does that mean they are planning on a conventional launch followed by maybe a hypersonic glide of an X37B style upper stage? In which case, how do they get that upper stage home again?

    Second, your typical C17 is perfectly capable of lifting a cargo of around 170,900lbs, or around 77,500kg - roughly 85 short tons. Falcon Heavy can lift 141,000lbs - 64,000kg - to Low Earth Orbit. Now, granted LEO != hypersonic delivery somewhere else on the planet... but that's still going to require FH-scale hardware to get anywhere close to the capacity of a single C17.

    I'm not familiar with the source for LOx or RP1 at sites such as Canaveral or Vandenberg, but at a guess they have infrastructure to support the loading and topping-off of propellants and oxidants prior to launch. So if there is any intent to fly ballistic returns, then there will also need to be quite a bit of thought put in to how all that infrastructure can be deployed to a forward operational base

    What might make sense - I'm certainly not qualified to judge - is the idea that maybe you have a series of pre-built "transit stations" around the world. These would have infrastructure to support a tail-down landing of a beefed-up first stage, but would have re-fueling services built on site. You could position these at strategic locations (somewhere in Europe, Middle East, Guam, Diego Garcia, etc.) and then use your ballistic delivery service to get multiple payloads to those forward staging areas, with on-site infrastructure able to deploy to "last leg" destinations. After all, you probably don't want to be trying to land a ballistic delivery vehicle through contended air space...

    It would be interesting to learn who suggested this first - SpaceX or the DoD. Either way, there's a possibility in here that the infrastructure and experience needed to operate this would be similar to the sort of ultra-rapid transit system that Musk has suggested in some of his Starship talks...

      They won't be using F9, which is like an aluminum foil drinking straw in comparison to Starship. F9 is long and thin specifically so that they can ship it from California over highways. Starship is more like a Chunky Soup can.

      Returns aren't necessarily a problem. A non-reusable equivalent would still be stuck where you landed it. The biggest problem that I see is potentially leaving half a dozen of the most advanced rocket engines ever (Raptor) in unfriendly territory. But that's hardly a requirement, sinc

    • It would be interesting to learn who suggested this first - SpaceX or the DoD.

      Vernor Vinge, in Rainbows End [wikipedia.org]. For which he received a Hugo award. And US military wish lists dating back to the early '70s when the space race was still in full swing. It's not a new idea. It's just becoming financially viable for the first time thanks to SpaceX's Starship design.

  • So what happens when China or N. Korea starts to offer the same service?

    Will the USA just wave it through, or will there be an almighty whinge about threats, offensive use and sovereignty / airspace (spacespace?).

      In that case we'd better get our asses to Mars, since that "service" is basically a heavy lift rocket without the first stage, and they'll have better places to go.
  • "But America isn't making any more C-17s, so while demand for logistics in the military is up, the supply of vehicles designed to carry stuff around the planet is down."

    USAF currently has 222 C-17s. Add another 52 C-5, and 202 C-130s. What is the basis for the claim that demand is up and supply down? We're not in much of a shooting war anymore. Have we ever had more? Are we about to start another Iraq?

  • I thought Amazon was already working on Prime 2 Hour Rocket Delivery. Seems like that could be pivoted to US military use pretty easily.

  • You want Starship Troopers? because this is how you get Starship Troopers.

  • I think the biggest challenge is being able to launch on short notice.

    Current rocketry doctrine is to go through a countdown process and if something goes wrong you delay to the next day or next week or next month.

    For this application that's not going to work. Maybe they need to have several Starships ready to go at all times? What about weather conditions?

    Or they're going to have to make these things super reliable. Which is why I think Elon is into this. This will give them the funding to become super rel

The truth of a proposition has nothing to do with its credibility. And vice versa.
