U.S. Defence Is Changing, From Who Builds It to How It Gets Delivered

26 September 2026 | Lightcone Advisors Research

A powerful piece of military equipment has limited value if it arrives after the threat has changed.

That challenge is pushing the U.S. defence sector to reconsider how it buys, builds and improves technology. New suppliers are gaining ground, software is becoming more important, and selected programmes are moving toward shorter development cycles.

The result could be a far-reaching change in an industry long associated with large contractors and lengthy projects. The U.S. Air Force and Navy have similar budgets allocated (as part of the annual defence budget) for spends on new hardware. The ask to Congress by the current U.S. government has been for U.S.$1.5 trillion for the Defence budget. Thats a whopping 50% increase from current levels. It remains to be seen if they will get the requested allocation, but it points to the establishment focusing on more Defence spending in the near term.

1. More companies can compete for important work

Building an entire aircraft or warship requires enormous resources. Developing a particular sensor, software system or autonomous capability can open the door to a wider range of suppliers.

The U.S. Air Force’s work on uncrewed aircraft illustrates this approach. It is developing a common framework that allows autonomy software from different suppliers to work across aircraft platforms. That could make it easier to introduce improvements without replacing the whole system. Established manufacturers remain important. What is changing is the opportunity for other companies to compete for parts of the work—and sometimes lead new programmes.

2. The buying process is starting to change

The ambition is to test useful technology earlier, learn from its performance and improve it in stages.

The Navy’s unmanned-vessel marketplace offers a concrete example. It selected seven companies’ entries for at-sea demonstrations, using existing commercial solutions to help accelerate delivery. Selection for testing, however, is not the same as widespread operational deployment.

The direction of change in these programmes is straightforward:

Less reliance on…	Greater emphasis on…
Defining every requirement years ahead	Testing and learning earlier
Buying tightly linked systems from one supplier	Connecting components from several suppliers
Waiting for a major replacement programme	Improving capabilities in smaller steps

These approaches are expanding unevenly. They do not remove the need for safety checks, reliable performance or military testing.

3. Delivering at scale will decide what lasts

A successful demonstration is only the beginning.

Suppliers still need factories, dependable components, trained workers and the ability to maintain equipment in service. Military users also need training and support before a new system becomes genuinely useful.

This is where the sector’s transformation faces its hardest test. Government auditors continue to highlight the gap between reform ambitions and actual delivery. Their emphasis is on getting functioning, relevant equipment to users, not simply awarding contracts faster.

The next phase of U.S. defence will likely involve established manufacturers and newer technology suppliers working in a more competitive industry.

The clearest measure of progress will be practical: can useful equipment reach military users sooner, be produced in sufficient numbers and improve as their needs change?
