The Pentagon has been inspired by SpaceX to use reusable rockets similar to the Falcon 9 and Starship to deliver military cargo all around the world.
The Pentagon is putting $50 million aside for a new program led by the US Space Force called Rocket Cargo. The new program will focus on researching and developing capabilities such as landing "a rocket on a wide range of non-traditional materials and surfaces," building "a rocket cargo bay and logistics for rapid loading and unloading" and air-dropping "cargo from the rocket after re-entry in order to service locations where a rocket or aircraft cannot possibly land."
From looking at what the Pentagon is describing in the new Rocket Cargo program, it's apparent that the US Air Force is looking to develop rockets similar, or better than SpaceX's Starship. The new military program is looking to develop rockets that can launch 30 - 100 tons of cargo, and are reusable. Currently, the only rocket that can do that is SpaceX's Starship rocket that is still in its late stages of development. For more information on this story, check out this link here.
