14th test flight of the two-stage Starship launch vehicle. 3rd flight of Starship V3 and the first Starship flight to deploy satellites (a group of Starlink satellites known as Starlink Group 31-1) into stable Low Earth Orbit.

The ship is expected to fly at an altitude approximately 275 km above Earth and complete approximately 6 orbits around the planet for nearly 10 hours, with splashdown targeted in the Pacific Ocean west of Chile.

The booster’s primary test objective on Flight 14 will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf.

Starship will deliver 26 Starlink V3 satellites to orbit for the first time, which aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation.

NSF coverage of SpaceX's Starship Flight 14. Starship’s first orbital mission is expected to fly at an altitude approximately 275 km above Earth and complete approximately six orbits around the planet over the course of a nearly 10-hour flight, with splashdown targeted in the Pacific Ocean to the west of Chile.
 
The Starship upper stage’s primary objectives include the first orbital insertion maneuver, the deployment of 26 Starlink V3 satellites, a deorbit burn using a single Raptor engine while in space, and a controlled reentry, descent, and splashdown in the Pacific Ocean. Starship will only execute a burn to enter orbit after the flight control team has ensured there is sufficient redundancy on hardware critical to doing the subsequent deorbit burn at the end of the mission.

Tranche 1 Transport Layer A is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites.

The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.

This launch carries 21 satellites manufactured by Northrop Grumman.
