DARPA To Develop Nuclear Powered Spacecraft


The Defense Advanced Research Projects Agency (DARPA) on May 4th issued a Solicitation for Proposals, for the next phase, of a Demonstration of a Nuclear powered Spacecraft.

The Project, called Demonstration Rocket for Agile Cislunar Operations (DRACO), started over a year ago when DARPA, selected a Preliminary Design for a Rocket Engine Reactor developed by General Atomics, and chose Two Conceptual Spacecraft designs by Blue Origin and Lockheed Martin.

The Next phases of the Program will focus on the Design, Development, Fabrication, and Assembly, of a Nuclear Thermal Rocket Engine. DARPA will conduct a “full and open competition” so this opportunity is Not limited to the Companies that participated in the First phase, a Spokesperson said. Proposals are due Aug. 5th.

The Goal is to launch a Flight demonstration of Nuclear Thermal Propulsion, in fiscal year 2026.

“A single award is anticipated” in Phase 2 of DRACO, the Spokesperson said.

The Objective to complete “preliminary and detailed design of a demonstration system and to construct and experimentally validate the nuclear thermal rocket flight engine.”

In Phase 3, the Demonstration system will be built to host a Nuclear Thermal rocket for an In-Orbit flight test.

DARPA is investing in Nuclear Propulsion for Space Vehicles, in hopes of successfully demonstrating an Engine that can fly across vast distances in cislunar space, the area between Earth and the Moon.

“Nuclear thermal propulsion achieves high thrust-to-weight similar to chemical propulsion but with two to five times the efficiency,” said DARPA.

NASA is participating in the Project, with the Goal of also using Nuclear Thermal propulsion for Long-duration Human Space flight Missions.

“Maneuver is more challenging in space due to propulsion system limitations,” said Maj. Nathan Greiner, Program Manager in DARPA’s Tactical Technology Office.

“To maintain technological superiority in space, the United States requires leap-ahead propulsion technology.”
