President Donald Trump’s US$175 billion (A$268.5 billion) Golden Dome missile defence initiative is triggering a seismic shift across the American defence sector, fusing space, artificial intelligence, and next-generation missile technology into an ambitious new strategic vision.
As NATO similarly reaffirms a significant increase in defence spending, the U.S.’s move signals a ramp-up of investment into new-age warfare technologies.
Set against a backdrop of new military technologies and emerging hypersonic threats, the project is fuelling a surge in defence funding, reinvigorating public-private partnerships, and rewriting the playbook for future military deterrence.
Supercharging Space and Security
Formally launched on January 27, 2025 and and partially funded by Trump’s sweeping “One Big Beautiful Bill”, the Golden Dome initiative began as an executive order instructing the Secretary of Defense to deliver “a reference architecture, capabilities-based requirements, and an implementation plan for the next-generation missile defense shield”.
The project has already secured US$24.4 billion in startup funds from Congress, part of a broader $157 billion defence boost.
The funding is designated “for enhancement of Department of Defense resources for integrated air and missile defence”, and is split across next-generation technology development and layered homeland defence measures.
A majority - $18.8 billion - has been earmarked for the research, development, and deployment of next-generation missile defence technologies. This includes investment in directed energy systems such as high-powered lasers, space-based interceptors for early threat engagement, and advanced sensor networks and hypersonic threat defences.
An additional $5.9 billion is allocated toward reinforcing layered homeland defence. These funds will accelerate the deployment of hypersonic defence systems, modernise ground-based missile defence platforms and radar infrastructure, and support upgrades to missile test ranges and the integration of new defensive systems.
“We do not have a homeland missile defence system that is intended to guard against adversary threats beyond North Korea or rogue state actors,” said Andrea Yaffe, the acting principal deputy assistant secretary of defence for space policy.
With hypersonic missiles capable of reaching targets in minutes, and manoeuvring to evade traditional defences, the Pentagon believes the Golden Dome is urgently needed to fill key gaps in existing homeland missile protection.

Corporate Contenders and Tech Coalitions
Major defence firms and tech startups are racing to secure their stake in the Golden Dome boom.
Northrop Grumman is centralising its efforts in Huntsville, Alabama, leveraging proximity to the Missile Defence Agency.
Meanwhile, companies like Palantir and Red Cat Holdings are emerging as key players in integrating AI and autonomous systems.
Palantir, which recently launched “Warp Speed for Warships” with the U.S. Navy, is expected to provide crucial AI integration across Golden Dome’s space and command networks.
Red Cat Holdings, a leader in affordable battlefield drones, recently secured a $260 million Army contract and is scaling up production to meet Pentagon demand for drones as consumable commodities.
Booz Allen’s “Brilliant Swarms” concept - a distributed network of satellites using AI to detect and intercept missile threats - is one of several proposed architectures under review.
Budget, Politics, and Pushback
The Pentagon’s FY2026 budget allocates an initial $25 billion to the Golden Dome, with more funding likely to follow as the program scales.
The overall national defence budget proposed by Trump surpasses US$1 trillion, a 13.4% increase over FY2025.
However, critics have raised red flags. A group of Democratic lawmakers warned that the initiative could become a “massively corrupt” boondoggle, citing projected costs of up to $542 billion and concerns over conflicts of interest with contractors like SpaceX.
They also questioned the strategic necessity of such a large-scale shield, fearing it could provoke further arms races with Russia and China.

Investment Surge and Space Economy Boom
While political fights simmer, investors are pouring into space and defence tech.
The Golden Dome is credited with driving a $3.1 billion surge in space startup funding in Q2 2025, the second-highest quarter on record, according to Seraphim Space.
Startups focused on rockets, satellites, and in-space infrastructure are benefiting from a growing perception that the Pentagon will be their most reliable customer over the next decade.
“More investors now see national security as a viable end market,” said Seraphim analyst Lucas Bishop.
Key Beneficiaries and Strategic Winners
As the Golden Dome initiative scales up, a handful of defence contractors and technology innovators stand out as early winners, poised to benefit both financially and strategically from the initiative’s massive budget and political momentum.
Northrop Grumman
Northrop Grumman is establishing itself as a foundational player in the missile defence supply chain.
With a new facility near the Missile Defense Agency in Huntsville, Alabama, the company is positioning to lead on integration and delivery of interceptor technologies and radar systems.
Its established relationships with the Pentagon and experience with ballistic missile systems give it a first-mover advantage in the race for Golden Dome contracts.
The most recent Northrop Grumman stock ratings have been mostly neutral. On April 24, Wells Fargo reiterated its Overweight rating, while UBS maintained its Buy rating on April 23 but reduced the price target from $583 to $571.
On the same day, RBC Capital rated the stock as Outperforming, and Susquehanna and Truist Securities reiterated their Positive and Buy ratings, respectively.
Earlier, on April 11, Goldman Sachs upgraded Northrop from Sell to Neutral and raised its price target sharply from $424 to $521.

Palantir Technologies
Known for its powerful data-fusion software used across U.S. intelligence agencies, Palantir is expected to provide the backbone of Golden Dome’s real-time threat analysis and decision-making infrastructure.
The company is already working with the Navy on AI-driven logistics and fleet control platforms, which could be adapted for space and missile integration.
Wedbush’s Dan Ives reiterated an Outperform rating and lifted his target to $160, citing Palantir’s potential to capitalise on federal AI spending.
Red Cat Holdings
A rising star in battlefield drones, Red Cat has carved a niche supplying low-cost, combat-ready UAVs.
With a $260 million U.S. Army contract already in place, it is seen as a key supplier for the autonomous surveillance and rapid-response components of the Golden Dome system.
Analysts call it a speculative but strategic play in the evolving drone warfare space. Northland analyst Michael Latimore initiated coverage of Red Cat Holdings with an Outperform rating and a $13 price target on 11 March.
L3Harris Technologies
L3Harris is investing heavily in advanced satellite sensors, including a new Indiana-based facility to support hypersonic missile detection.
Its existing government contracts and deep portfolio of communications tech make it a contender for both space-based sensing and C2 (command-and-control) integration within the Golden Dome framework.
TD Cowen analyst Gautam Khanna raised L3Harris Technologies’ price target from $240 to $270, maintaining a Buy rating on improved order momentum and progress on delayed programs.
Anduril Industries
A new-generation defence startup founded by Oculus co-founder Palmer Luckey, Anduril is working on autonomous weapons and surveillance systems.
With the Pentagon seeking distributed, automated defences that reduce human decision lag, Anduril’s sensor fusion and AI-driven targeting capabilities make it a strong fit for Golden Dome’s more experimental components.
Strategic Shifts and Global Implications
The Golden Dome project also carries weight on the global stage. Canada has been encouraged to partner on the project as part of broader trade and security negotiations with the U.S.
In the Indo-Pacific, the initiative aligns with American efforts to build industrial defence ties through AUKUS and the Partnership for Indo-Pacific Industrial Resilience (PIPIR).
At home, the project faces workforce hurdles: the Space Force has lost 14% of its civilian staff this year, raising concerns about knowledge drain just as the project gets underway.
Looking Ahead
Golden Dome is a bold attempt to reclaim America’s technological and strategic edge.
With a tight three-year timeline, unproven technologies like space-based lasers, and a still-uncertain funding trajectory, success is far from guaranteed.
But for now, the momentum is real, and the money is flowing.
Whether it ultimately delivers a functioning missile shield or not, the initiative is already reshaping how the U.S. approaches defence, industry, and alliances in the 21st century.
