U.S. Space Development Agency (SDA)

The Space Development Agency has issued a solicitation for proposals for its satellite constellation’s Tranche 2 Transport Layer.

Agency launches 10 missile warning and communication satellites, putting satellites on orbit 30 months after contract approval.

The Pentagon’s SDA model is to launch large numbers of small satellites to low Earth orbit at about 1,000-km altitude.

The launch marks the start of the military's Proliferated Warfighter Space Architecture.

When the U.S. Space Development Agency’s first ten satellites become operational, it will mark the start of a massive change in the Pentagon’s architecture.

SpaceX scrubbed the launch of the Space Development Agency’s first official batch of satellites March 30.

The U.S. Space Development Agency is poised to test its small-satellite constellation.

The Space Development Agency (SDA) intends to track a hypersonic missile defense test next spring, Director Derek Tournear says.

The Space Development Agency (SDA) plans to launch its first batch of satellites, Tranche 0, before the end of March.

Astroscale has raised a $76 million Series G round of capital and plans to jointly develop satellite buses with Mitsubishi Electric.

Terran Orbital has won a $2.4 billion contract to build 300 small satellites for Rivada Space Networks.

The U.S. Space Force wants terminals that will operate between two GEO spacecraft.

The “Sabre” system would collect and relay telemetry data from U.S. missile test ranges.

SDA director Derek Tournear joins Aviation Week editors on Check 6 to discuss how its system of space tracking and transport satellites will revolutionize the U.S. military and the challenges it will face along the way.

The U.S. Space Development Agency (SDA) awarded L3Harris and SpaceX contracts to each build four satellites for detecting and tracking ballistic and hypersonic missiles.

The Space Development Agency is moving forward with plans to put on contract the initial phases of its ambitious next-generation U.S. Defense Space
