The US Space Force released a list Friday of a dozen companies working on Space-Based Interceptors for the Pentagon\u2019s Golden Dome initiative, a multilayer defense system to shield US territory from drones and ballistic, hypersonic, and cruise missile attacks.<\/p>\n

The roster of Golden Dome Space-Based Interceptor (SBI) contractors, some of which were previously reported, includes Anduril Industries, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Lockheed Martin, Northrop Grumman, Quindar, Raytheon, Sci-Tec, SpaceX, True Anomaly, and Turion Space.<\/p>\n

The Space Force made 20 individual awards to the 12 companies in late 2025 and early 2026 using an acquisition mechanism known as Other Transaction Authority, or OTA, agreements. OTAs allow the Pentagon to bypass federal acquisition regulations and cast a wide net to attract a larger number of potential contractors and are especially useful for rapid prototyping. That is exactly what the Space Force wants to see with the first phase of the SBI program.<\/p>\n

The agreements have a combined value of up to $3.2 billion and will capitalize on a mix of public and private investment to move SBIs closer to testing in low-Earth orbit.<\/p>\n

Officials have not released details of each company\u2019s contribution, but the contractors come to the SBI program with different skill sets. The agreements are for early-stage development and tech demos, not for full-scale production, which will come with a significantly higher price tag.<\/p>\n

\u201cNo additional information will be available at this time due to operational security requirements regarding the SBI program,\u201d the Space Force said in a statement.<\/p>\n

The usual players<\/h2>\n

Some of the companies on the list, such as SpaceX, Lockheed Martin, and Northrop Grumman, are well known in the space industry. They seem positioned to become lead or prime contractors. Others, such as Anduril and True Anomaly, are full-stack developers that are newer to the space industry but have lofty ambitions in the national security market. Quindar and SciTec, a subsidiary of Firefly Aerospace, have expertise in software. Turion develops space sensing technology, and GITAI USA had its start as an in-space robotics company.<\/p>\n

Booz Allen Hamilton is best known as an integrator and data services company serving the defense sector. General Dynamics provides \u201ccritical communications and electronics\u201d for space missions and was already selected to develop the ground control system for the military\u2019s network of low-Earth orbit missile tracking and data connectivity satellites, according to its website. Raytheon, also known as RTX, builds missile warning sensors and ground control software (with a not-so-stellar recent track record), and manufactures small satellites through its subsidiary, Blue Canyon Technologies.<\/p>\n

\u201cAdversary capabilities are advancing rapidly, and our acquisition strategies must move even faster to counter the growing speed and maneuverability of modern missile threats,\u201d said Col. Bryon McClain, program executive officer for space combat power at Space Systems Command.<\/p>\n

The OTA acquisition framework for SBIs \u201cattracted both traditional and non-traditional vendors, while harnessing American innovation, and ensuring continuous competition,\u201d McClain said in a Space Force press release. \u201cWith the commitment and collaboration of these industry partners, the Space Force will demonstrate an initial capability in 2028.\u201d<\/p>\n

In addition to SBIs to defend against missile attacks, Golden Dome will include lower-altitude and ground-based munitions suited for eliminating drones and other smaller, slower-moving aerial weapons. All of this \u201cmust be integrated with Artificial Intelligence to counter the\u202fspeed, maneuverability, and lethality of the threats,\u201d the Space Force said in a press release.<\/p>\n

The US and Israeli war with Iran has been an acid test for missile defense. Ground- and sea-based US and Israeli interceptors have shot down thousands of missiles and drones since the first wave of Iranian ballistic missiles launched toward Israel in 2024, with a success rate of more than 90 percent. But the war has also shown that missile defenses are not impenetrable, with at least seven US service members killed by hostile action. Several costly early warning radars and US military airplanes in the Gulf states have been damaged or destroyed on the ground by Iranian drone or missile strikes.<\/p>\n

,<\/p>\n

The Iran war has also diminished existing stocks of US missile interceptors, which the Pentagon plans to integrate with Golden Dome to form ground, sea, and airborne layers to go along with the space layer in low-Earth orbit. Air Force Lt. Gen. Heath Collins, director of the Missile Defense Agency, told a House subcommittee April 15 that it will take a \u201cnumber of years to replenish\u201d the interceptors used in less than two months of the Iran war.<\/p>\n

Should this be the priority?<\/h2>\n

Gen. Michael Guetlein, the Space Force general serving as director of the Golden Dome program, said replenishing the interceptors used up in the Iran war will have no schedule impact and \u201cno direct cost impact\u201d to Golden Dome, which the Trump administration says will cost $185 billion to develop and deploy.<\/p>\n

Many analysts dispute the cost and schedule projections. Guetlein said outside estimates, some of which peg Golden Dome\u2019s cost at several trillion dollars, don\u2019t take into account what the Pentagon is actually building. However, defense officials are keeping much of the Golden Dome architecture secret, so it\u2019s hard to know what it entails. Getting any working SBI capability into orbit in the next two-and-a-half years would require herculean efforts by the Space Force and the defense industry. Contractors would have to drastically cut down on the time it usually takes to deliver space systems of lesser complexity.<\/p>\n

SBIs are widely seen as the most challenging and expensive element for Golden Dome. Space-based missile tracking sensors, satellite networks for targeting and data relay, and terrestrial interceptors already exist or will soon be operational. But SBIs may not be the panacea administration officials argued for when President Donald Trump signed the executive order for Golden Dome in January 2025. The order has a clear requirement for the Pentagon to develop plans for the deployment of \u201cproliferated Space-Based Interceptors capable of boost-phase intercept.\u201d<\/p>\n

\u201cWe are so focused on affordability. If we cannot do it affordably, we will not go into production,\u201d Guetlein said in an April 15 hearing before the House Armed Services Strategic Forces subcommittee.<\/p>\n

,<\/p>\n

\u201cWe are looking at the threats from a multi-domain perspective to make sure I have redundant capabilities and I don\u2019t have single points of failure,\u201d he added. \u201cSo, if boost-phase intercept from space is not affordable and scalable, we will not produce it, because we have other options to get after it.\u201d<\/p>\n

Boost-phase intercepts would aim to destroy a missile within a few minutes after its launch, when it is still within or close to the atmosphere. In those early minutes, the heat from the missile\u2019s exhaust plume would make it relatively easy to detect and target, but an interceptor in orbit would require a powerful impulse to reach it. The military is also interested in using SBIs for midcourse intercepts, when a missile is coasting through space, and during glide phase as they reenter the atmosphere. By then, though, a missile may have released countermeasures or multiple reentry vehicles.<\/p>\n

Rep. Seth Moulton (D-Mass.) is the top Democrat on the House Strategic Forces subcommittee. He questions the premise that Golden Dome could deter future attacks, pointing to Iran\u2019s sustained missile and drone strikes across the Middle East, despite the operational success of US and Israeli defenses.<\/p>\n

\u201cThat basic theory seems blown out of the water by our current experience, which is that we have incredibly robust missile defense across the Middle East,\u201d Moulton said. \u201cWe\u2019ve been singing its praises in a very bipartisan way, and yet it has not stopped Iran in the least from shooting a lot of missiles and drones at us and our allies.\u201d<\/p>\n

\u201cI think we\u2019re talking about a regime that may be beyond deterrence,\u201d said Marc Berkowitz, the assistant secretary of defense for space policy, referring to Iran. \u201cThey have, for decades, pursued nuclear weapons and ballistic missiles.\u201d<\/p>\n

The Trump administration is requesting $17 billion for Golden Dome in fiscal-year 2027, which begins October 1. Nearly all of the requested funding is packaged in a reconciliation bill, not in the White House\u2019s regular annual funding request. While Republican lawmakers still voice support for Golden Dome, there is little appetite for the partisan budget battle a party-line reconciliation bill would spark ahead of this year\u2019s midterm elections, Politico reported Thursday.<\/p>\n

Putting the Golden Dome funding request in a bill that may never reach the House or Senate floor is \u201cnot great signaling by this White House about the supposedly drastic need for Golden Dome,\u201d a former defense official told Politico.<\/p>\n","protected":false},"excerpt":{"rendered":"
