Defense boost for space startups

The White House is asking Congress for $1.5 trillion in defense spending for fiscal year 2027, up about $445 billion from the prior year’s level, and the jump is so large that even the Space Force budget would more than double under the plan. (whitehouse.gov) (spacenews.com) That does not mean $1.5 trillion lands in company bank accounts tomorrow, because this is a presidential request, not an enacted law, and Congress still has to write and pass the actual spending bills. (cbsnews.com) (airandspaceforces.com) The part that has startup investors paying attention is where the money is pointed: missile defense, space sensors, launch, ships, munitions, and military production capacity. The White House fact sheet names “Golden Dome for America” as a centerpiece, and SpaceNews reports the Space Force request at about $71 billion. (whitehouse.gov) (spacenews.com) “Golden Dome” is the administration’s term for a layered missile shield, which means a stack of systems that see a launch, track it through space, and try to stop it before impact. That kind of architecture needs rockets to launch satellites, infrared sensors to spot heat, software to fuse the data, and interceptors to do the shooting. (whitehouse.gov) (spacenews.com) That is why a company like Rocket Lab shows up in this conversation even though it is much smaller than Lockheed Martin or RTX. In December 2025, Rocket Lab said it won an $816 million prime contract to build a missile-defense satellite constellation for the U.S. Space Force. (rocketlabcorp.com) Rocket Lab is not alone in that lane. On December 19, 2025, the Space Development Agency awarded about $3.5 billion across four contracts for 72 tracking satellites, with awards to Lockheed Martin, Rocket Lab, Northrop Grumman, and L3Harris. (sda.mil) (breakingdefense.com) L3Harris got one of those awards directly, saying its contract was worth up to $843 million for 18 infrared satellites. Infrared satellites are basically heat-seeking cameras in orbit, and they are central to tracking fast missiles, including hypersonic ones. (l3harris.com) SpaceX fits for a different reason: it is the trucking network that gets national security payloads into orbit. The U.S. Space Force said in April 2025 that SpaceX received Phase 3 Lane 2 launch contracts with an anticipated value of about $5.9 billion, the largest share among the three winners. (spaceforce.mil) The older primes are still sitting in the middle of the table. Lockheed Martin said in its 2025 annual report that demand was “unprecedented,” and its business already spans missiles, fire control, rotary systems, and space, which is exactly where this budget proposal is trying to pour money. (lockheedmartin.com) RTX is the same story from the interceptor side, because missile shields are not just satellites and launchers. They also need the missiles, radars, and command systems that companies like RTX have been building for years. (whitehouse.gov) (cbsnews.com) General Dynamics and HII are less about orbit and more about the rest of the buildup. General Dynamics is one of the Navy’s main submarine builders, and HII builds carriers, destroyers, amphibious ships, and undersea systems, so a budget tilted toward ships and industrial capacity helps them even if the headline starts in space. (gd.com) (hii.com) Spirit AeroSystems is the oddest name on the list because it is known first for commercial aircraft structures, not missile defense. Its own filings show the defense angle comes mainly through military derivatives tied to Boeing programs such as the P-8, so it is more of a supplier bet than a pure Pentagon bet. (spiritaero.com) (cloudfront.net) So the cleanest way to read this is not “every defense stock wins.” It is that a budget request built around missile defense and a $71 billion Space Force would favor companies already holding the right contracts, the right factories, or the right launch pads, and right now that list includes both giant primes and a few younger space firms that finally have Pentagon-scale work in hand.
