Link to full articleThe USMC has documented an ambitious need for a spacecraft that can transport up to 13 marines through space to any spot on Earth within 2h. The official concept - dubbed Small Unit Space Transport Insertion - was launched in 2002, but its requirement for an orbital-class, reusable spacecraft has pushed it perhaps decades into the future.
"They set the bar very, very high," Damphousse says. "In this latest iteration we said: 'Well, do we necessarily need that near-instantaneous crisis response? Do we need to attain orbit? Or is this something that can be shorter range? Let's look at the suborbital band'."
But meeting such "near-term" needs for suborbital transport should only be the beginning, he adds. The ultimate goal is to scale up the system to meet the USMC's documented requirement for a manned vehicle that can move small units anywhere in the world within 2h. "People talk about putting boots on the ground, but it's more than that," Damphousse says. "It's eyes, ears and brains on the ground - what some folks in the Marine Corps call situational curiosity."
The next step after the conference has not been defined. Damphousse's team will write up after-action reports based on discussions between industry and military officials. Any decision to proceed to a demonstrator or acquisition problem will require a decision to commit funding. "The next phase may not be anything," he notes. "We have to figure out if there is a next phase and what it should be."
Another job for Spaceship Two (or a derivative?)
Spaceship Two is intended to be reusable, could it be modified as expendable perhaps with a non reusable (but more powerful) main engine and/or dropable boosters (maybe reusable) to launch from a short airstrip or maybe even ship?
