SpaceX Starshield

Starshield is a business unit of SpaceX creating purpose-built low-Earth-orbit satellites designed to provide new "disruptive" military space capabilities to U.S. and allied governments.^[1][2][3][4] Starshield was adapted from the global communications network Starlink but brings additional capabilities such as target tracking, optical and radio reconnaissance, and early missile warning.^[5][6][7][8] Primary customers include the Space Development Agency, National Reconnaissance Office and the United States Space Force.^[5][9][10] As of 2024, at least 16 Starshield satellites have been launched, with an unknown number of additional satellites being launched in May 2024 as part of NROL-146.^[11]

While SpaceX president and COO Gwynne Shotwell has indicated that there is little information she is allowed to disclose about Starshield, she has noted "very good collaboration" between the intelligence community and SpaceX on the program.^[1] The U.S. Congressional Research Service reports that future satellites in Starshield's participating SDA program may wield interceptor missiles, hypersonic projectiles, or directed energy weapons,^[8] with the program's founder^[6] adding "since Reagan’s day, technology has advanced enough that putting both sensors and shooters in space is not only possible but relatively easy."^[7] According to SDA Director Derek Tournear, later satellites will take on the “extremely difficult” task of maintaining contact with missiles in flight.^[12]

The former four-star general Terrence O'Shaughnessy, who previously ran U.S. Northern Command, is the vice president for SpaceX's Special Programs Group who is thought to be involved with Starshield.^[1] The Wall Street Journal reported that Starshield's online job postings required people with top-secret clearances, as well as experience working with the Defense Department and intelligence community — such as representing Starshield to Pentagon combatant commands.^[1]

The first satellites were designed for the Space Development Agency and outfitted with advanced infrared sensors meant to detect and track ballistic and hypersonic missiles.^[13] In 2021, Starshield had entered a $1.8 billion classified contract with the U.S. government, revealed in 2023,^[1] to construct hundreds of spy satellites for continuous real-time monitoring of targets around the globe.^[9] These are slated to begin operations from May 2024, starting with NROL-146. These satellites are made in cooperation with Northrop Grumman.^[14]

The Starshield name was publicly announced December 2022,^[15] however in 2021, Starshield had already entered a $1.8 billion classified contract with the U.S. government, revealed in 2023.^[1] In the documents of the contract, SpaceX says that funds from the contract were expected to become an important part of the revenue mix of the company after 2021.^[1] Reuters revealed in 2024 that this contract was between the National Reconnaissance Office and SpaceX, and for a spy satellite network consisting of hundreds of satellites functioning as a swarm.^[9] The satellites will have imaging capabilities, and the satellite network will enable the US government to have continuous surveillance of nearly anywhere around the globe.^[9] Starshield also plans to be more resilient to attack from other powers.^[9] Starshield's imaging capabilities are designed to have superior resolution over most existing U.S. government spying systems. Northrop Grumman was selected to partner with SpaceX, with insiders noting that "it is in the government's interest to not be totally invested in one company run by one person".^[16]

As early as 2020, SpaceX was designing, building, and launching customized satellites based on variants of the Starlink satellite bus for the National Reconnaissance Office (NRO).

In October 2020, SDA awarded SpaceX an initial $150 million dual-use contract to develop 4 satellites to detect and track ballistic and hypersonic missiles.^[13] The first batch of satellites were originally scheduled to launch September 2022 to form part of the Tracking Layer Tranche 0 of the Space Force's National Defense Space Architecture.^[17] The launch was rescheduled multiple times but it eventually launched in April 2023.^[18][19]

In 2020, SpaceX hired retired four-star general Terrence J. O'Shaughnessy who according to some sources is associated with Starlink's military satellite development and according to one source is listed as a "chief operating officer" at SpaceX.^[20][21] While still in active duty, O'Shaughnessy advocated before the United States Senate Committee on Armed Services for a layered capability with lethal follow-on that incorporates machine learning and artificial intelligence to gather and act upon sensor data quickly.^[22] As of 2024, Terrence O’Shaughnessy reportedly has had a high-level role at Starshield, though there is no indication that SpaceX is working on anything related to lethal weapons.^[1]

SpaceX was not awarded a contract for the larger Tranche 1, with awards going to York Space Systems, Lockheed Martin Space, and Northrop Grumman Space Systems.^[23]

As Starlink was being relied on in the Russo-Ukrainian war, expert on battlefield communications Thomas Wellington argued that Starlink signals, because they use narrow focused beams, are less vulnerable to interference and jamming by the enemy in wartime than satellites flying in higher orbits.^[24]

Another Starshield contract was announced in September 2023, involving communications-focused services for U.S. Space Systems Command.^[25][26] This contract with the US Space Force plans to provide customized satellite communications for the military.^[27] This is under the Space Force's new "Proliferated Low Earth Orbit" program for LEO satellites, where Space Force will allocate up to $900 million worth of contracts over the next 10 years. Although 16 vendors are competing for awards, the SpaceX contract is the only one to have been issued to date.^[25][27] The one-year Starshield contract was awarded on September 1, 2023.^[10] The contract is expected to support 54 mission partners across the Army, Navy, Air Force, and Coast Guard.^[10]

In February 2024, the United States House Select Committee on Strategic Competition between the United States and the Chinese Communist Party sent a letter to Elon Musk stating that the Starshield program was potentially in breach of contract for not providing access to U.S. troops stationed in Taiwan when "global access" was "possibly" required by the contract.^[28][29] SpaceX responded that they were in full compliance with their U.S. government contracts. SpaceX had notified the Select Committee a week earlier that they were misinformed, but the Select Committee "chose to contact media before seeking additional information [regarding Starshield military use in Taiwan]".^[30]

In the context of military communication satellites, Col. Eric Felt, director of space architecture at the office of the assistant secretary of the Air Force for space acquisition and integration, said that there are plans to acquire at least 100 Starshield-branded satellites for this purpose by 2029. He said that while the military is an active user of SpaceX's commercial Starlink service, they also want to take advantage of the company's dedicated Starshield product line. Clare Hopper, head of the Space Force’s Commercial Satellite Communications Office (CSCO) stated that demand for Starlink's commercial service is "off the charts" and that currently all of their supported users are still using the commercial Starlink satellite constellation, but that the DoD has "unique service plans that contain privileged capabilities and features that are not available commercially".^[31]

Between 2020 and March 2024, a dozen Starshield prototypes and operational satellites were launched on Falcon 9.^[9] Reuters reported that these satellites have never been acknowledged by SpaceX or the US government and remain classified.^[9]

Images were posted online^[32] of the two SpaceX-built Space Development Agency Tranche 0 Flight 1 Tracking Layer infrared imaging satellites that launched on 2 April 2023.^[33] After the launch of Starlink Group 7-16, only 20 of a batch of 22 starlink satellites were catalogued, and the remaining two were later designated as USA-350 and USA-351.^[34]
