US Air Force explores space-based cargo operations, confirms talkswith SpaceX
"As for what space cargo operations could look like, the previous head of Air
Mobility Command, Gen. Carlton Everhart, espoused the possibility of moving cargo using rockets during a Defense Writers Group breakfast in August." "Apart from cargo operations, such a focuses space presence could help with pre- positioning equipment and supplies in orbit, ready to be dropped to Earth."

See: https://www.defensenews.com/digital-...s-with-spacex/ From above: One potential would be SpaceX?s next-generation reusable BFR rocket, currently under development. During the roundtable, Miller confirmed that the Air Force had spoken to SpaceX about the idea. Interesting. Sounds like they're considering BFR as a military P2P cargo transport. It would certainly be faster than any other form of transport over great distances. True, but the real question will be what you need for a useful landing platform and the ability to refuel. A C-130 may not be fast, but can land at most airfields and its fuel is available worldwide. Where you need the speed of a BFR, I suspect you won't have the other infrastructure in place.

The current discussion with the US military is over using BFR/BFS for space based *cargo* transport. I also said: | I assert that BFR/BFS would be little different than the V-22 | in terms of both unique capabilities and could be little | different when it comes to its reliability as an air/space | transport craft. Note that we don't see V-22s or a commercial derivative of the same technology being used in commercial passenger carrying transport quite yet. The V-22 has tended to crash more often than FAA certified commercial passenger carrying transports. And that's not for a lack of trying: AgustaWestland AW609 https://en.wikipedia.org/wiki/AgustaWestland_AW609 As far as I can tell, the AW609 is not yet certified. ERIC ADAMS, TRANSPORTATION, 02.07.1809:00 AM GET RICH SO YOU CAN FLY IN A V-22 OSPREY-INSPIRED PRIVATE PLANE https://www.wired.com/story/leonardo-aw609-tilt-rotor/ From above: Whether or not the AW609 can establish itself in the aviation market, Leonardo expects it will enter commercial service in earnest in 2019, after certification. I wish them luck. It's a cool aircraft. Jeff -- All opinions posted by me on Usenet News are mine, and mine alone.

Pretty much anyplace with a hard surface will do for landing. A C-130 may not be fast, but can land at most airfields and its fuel is available worldwide. BFS burns LNG, which is at least as common as aviation grade kerosene. Where you need the speed of a BFR, I suspect you won't have the other infrastructure in place. The real problem is that unless you have a fleet of the things you've just put a relatively small number of troops way behind enemy lines without support. -- You have never lived until you have almost died.

BFS burns LNG, which is at least as common as aviation grade kerosene. BFS will burn liquid methane. I'm not sure what would happen if you replaced the methane with LNG. Possibly it would fly, possibly it would go kaboum. Even if LNG is mostly liquid methane, there typically is near 10% of ethane, propane, butane and small amounts of other stuff. In some cases the difference can have consequences. Alain Fournier |
