A cargo-delivery rocket that can deliver weapons via space to anywhere in the globe within an hour is being developed by Elon Musk's SpaceX for the US military

The system would allow materials to be transported the 7,500-odd miles from Cape Canaveral, Florida, to the US-run Bagram airfield in Afghanistan in under an hour.

In contrast, a Boeing C-17 Globemaster III — a military transport aircraft the US owns a 233-strong fleet of, that can fly at maximum of 590mph — would take 15 hours. The rocket will be able to carry an 80 ton payload, similar to that of a single C-17 — and proof-of-principle tests are expected to begin next year.

The collaboration — which will also include Texas aerospace firm xArc — was announced by US Transportation Command's General Stephen Lyons.

The first steps in the project will involve an assessment of the potential costs and challenges that will need to be overcome to deliver cargo globally in an hour.

'Think about the speed associated with that,' General Lyons said at the conference. 

'I can tell you SpaceX is moving very, very rapidly in this area. I’m really excited about the team that’s working with SpaceX.'

SpaceX has previously demonstrated the ability to vertically land and reuse the booster rockets for its Falcon 9 system onto drone ships out at sea. However, the aerospace technology firm has never landed a rocket carrying a full payload — and the newly-proposed rocket would carry four times the cargo.

Beyond speed, one major advantage of ferry military cargo via rocket is that — at present — flying over another country via orbit does not require permission from foreign governments, unlike when transporting goods by air.

Key to the realisation of a rocket-based cargo-carrying system is the ability to ensure safe and accurate landings.

'We send humans up into space safely, so sending cargo via orbit is not a problem. The challenge will be bringing it down,' Douglas Barrie — an aerospace expert from the London-based International Institute for Strategic Studies — told the Times.

'How would they bring it down, by parachute or controlled descent? And could it be guaranteed to arrive in the right place?'

Mr Barrie also questioned the cost and the very concept, adding: 'Normally you associate space-based delivery with intercontinental ballistic missiles.'

'What would be the urgency for sending military cargo through space?'
