Lockheed Martin gets another mention here in relation to the Golden Dome, as does RTX.
The other thing I noticed is that the article says "Notably, the slides did not mention Mr Elon Musk’s SpaceX,
which was part of a bid for Golden Dome contracts alongside software maker Palantir and defence systems manufacturer Anduril."
Is it merely a coincidence that Jonathan Tapson also mentioned both Palantir and Anduril in his Washington post?

WASHINGTON - The Trump administration's flagship Golden Dome missile defence system will include four layers - one satellite-based and three on land - with 11 short-range batteries located across the continental US, Alaska and Hawaii, according to a US government slide presentation on the project first reported by Reuters.
The slides, tagged “Go Fast, Think Big!” were presented to 3,000 defence contractors in Huntsville, Alabama, last week and reveal the unprecedented complexity of the system, which faces an ambitious 2028 deadline set by US President Donald Trump.
The system is estimated to cost US$175 billion (S$224.53 billion), but the slides show uncertainties still loom over the basic architecture of the project because the number of launchers, interceptors, ground stations, and missile sites needed for the system has yet to be determined.
"They have a lot of money, but they don't have a target of what it costs yet," said one US official.
So far, Congress has appropriated US$25 billion for Golden Dome in Mr Trump’s tax-and-spend Bill passed in July.
Another US$45.3 billion is earmarked for Golden Dome in his 2026 presidential budget request.
Intended as a multi-layered missile defence shield for the United States, Golden Dome draws inspiration from Israel's Iron Dome, but is significantly bigger due to the geography it will need to protect and the complexity due to the varied threats it will face.
According to the slides, the system architecture consists of four integrated layers: a space-based sensing and targeting layer for missile warning and tracking as well as "missile defence" and three land-based layers consisting of missile interceptors, radar arrays, and potentially lasers.
One surprise was a new large missile field - seemingly in the Midwest according to a map contained in the presentation - for Next Generation Interceptors (NGI) which are made by Lockheed Martin and would be a part of the "upper layer" alongside Terminal High Altitude Area Defense (Thaad) Aegis systems which are also made by Lockheed.
NGI is the modernised missile for the Ground-Based Midcourse Defence (GMD) network of radars, interceptors and other equipment - currently the primary missile defence shield to protect the United States from intercontinental ballistic missiles from rogue states.
The US operates GMD launch sites in southern California and Alaska. This plan would add a third site in the Midwest to counter additional threats.
Other technical hurdles the slides identified included communication latency across the "kill chain" of systems.
Contractors such as Lockheed, Northrop Grumman, RTX, and Boeing have a variety of missile defence systems.
Notably, the slides did not mention Mr Elon Musk’s SpaceX, which was
part of a bid for Golden Dome contracts alongside software maker Palantir and defence systems manufacturer Anduril.
The Pentagon said it is gathering information "from industry, academia, national labs, and other government agencies for support to Golden Dome" but it would be "imprudent" to release more information on a programme in these early stages.
One key goal for Golden Dome is to shoot targets down during their “boost phase,” the slow and predictable climb through the Earth's atmosphere of a missile.
Rather, it seeks to field space-based interceptors that can more quickly intercept incoming missiles.
The presentation highlighted that the United States "has built both interceptors and re-entry vehicles" but has never built a vehicle that can handle the heat of reentry while targeting an enemy missile.
The last lines of defence dubbed the "under layer" and "Limited Area Defence" will include new radars and current systems like the Patriot missile defence system and a new "common" launcher that will launch current and
future interceptors against all threat types.
These modular and relocatable systems would be designed to minimise reliance on prepared sites, allowing for rapid deployment across multiple theatres.
Space Force General Michael Guetlein, confirmed in July to lead the Golden Dome project, has 30 days from his July 17 confirmation to build a team, another 60 days to deliver an initial system design, and 120 days to present a full implementation plan, including satellite and ground station details, people briefed on a memo signed by Defence Secretary Pete Hegseth have told Reuters.
