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.<img src="https://i.dailymail.co.uk/1s/2020/10/09/10/34186860-8822659-image-a-1_1602237038466.jpg" alt="A cargo-delivery rocket that can deliver weapons and hardware to anywhere in the globe within an hour is being developed by Elon Musk's SpaceX for the US military.

'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.At present, each C-17 cargo aircraft cost the US military around $218 million — it is unclear at present how this, and operating costs, would compare with the rocket.<img src="https://i.dailymail.co.uk/1s/2020/10/09/11/34186858-8822659-A_Boeing_C_17_Globemaster_III_a_military_transport_aircraft_whic-a-4_1602238144691.jpg" alt="A Boeing C-17 Globemaster III (pictured) — a military transport aircraft which the US owns a 233-strong fleet of, that can fly at up to 590mph — would take 15 hours to ferry cargo from Florida to Afghanistan.

SpaceX's proposed cargo rocket could make the journey within an hourKey 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?' WHY DOES SPACEX RE-USE ROCKETS AND OTHER PARTS?SpaceX tries to re-use rockets, payload fairings, boosters and other parts to try to cut down on the cost of each rocket mission.The total cost of one of its Falcon 9 launches is estimated to reach £44 million ($61m), while each of its larger Falcon Heavy flights costs £65 million ($90m).The space company has previously re-used first-stage and second-stage rocket boosters, in addition to one of its previously flown Dragon capsules.The Dragon spacecraft are used as the final stage of SpaceX missions to resupply the International Space Station.<img src="https://i.dailymail.co.uk/i/pix/2018/02/06/20/48F04B6000000578-5356825-image-a-30_1517950740224.jpg" alt="In an incredible accomplishment, the Falcon Heavy's side boosters landed smoothly back down to Earth on two separate launchpads about 8 minutes in's side boosters landed smoothly back down to Earth on two separate launchpads about 8 minutes in" class="fr-fic fr-dii fr-draggable " style="" /><img src="https://i.dailymail.co.uk/i/pix/2018/02/06/20/48F04B5100000578-5356825-image-a-31_1517950740437.jpg" alt="'The Falcons have landed' the announcers said, as people cheered and whooped wildly in the background'The Falcons have landed' the announcers said, as people cheered and whooped wildly in the background" class="fr-fic fr-dii fr-draggable " style="" />In an incredible accomplishment, the Falcon Heavy's reused side boosters landed smoothly back down to Earth on two separate launchpads about 8 minutes in.SpaceX is currently testing a system to recover the fairings of its Falcon 9 rockets. The payload fairings are clam shell-like nose cone halves that protect the craft's payload.SpaceX recovered a payload fairing for the first time in 2017.During its first Falcon Heavy launch in February 2018, the firm landed two of the firms side boosters simultaneously on separate launchpads.</blockquote>
