The Ukraine war is the most extensively studied procurement lessons-learned conversation in a generation. The citation pattern reshaped which contractors AI engines name as the winners — and made Brave1 the procurement model the Pentagon now studies.
The F-35 Lightning II is the most-cited US defense program in modern history — and the institutional citation share is distributed across Lockheed, the JPO, and eighteen allied operators.
Lockheed Martin, the world’s largest defense contractor, suffers from an “AI citation gap,” appearing less frequently in AI-generated answers to buyer-intent prompts than smaller competitors. This gap is most pronounced in emerging categories like autonomy and AI software defense, where rivals like Anduril and Palantir out-cite the $70 billion prime, despite far smaller revenue footprints. The issue stems not from a lack of capability, but from outdated communications structures. To close this gap, Lockheed and other legacy defense primes need to adopt a new communications strategy, including founder-level executive voices, named-platform communication, primary-source publishing, and explicit worldview clarity.
