Aerospace & Defense · AI Perceptions snapshot

AI answers about aerospace and defense keep returning to Boeing, whatever the question asked.

Across questions on trust, safety, employers and risk, the assistants reach for the same few large primes, with Boeing first and Lockheed Martin close behind. The press is covering a different set of companies, and SpaceX, Honeywell and Airbus draw far more coverage than their share of answers would suggest.

Storylines in the answers

The threads the answers kept returning to, and the brands attached to each.

  1. Boeing as the default name, in trust and in risk questions
  2. Government contracts, missiles and oversight belong to the established primes
  3. Commercial aircraft as a two-maker story, with Embraer in regional and business jets
  4. Space and value questions point to newer names, not the primes

What the assistants say

This snapshot covers answers from ChatGPT, Claude, Gemini, Perplexity and Grok, measured on 2026-09-29. The questions never named a company. Even so, Boeing, Lockheed Martin and Northrop Grumman fill most of the answers. Boeing is the top-named brand in most of the question groups. That includes trust and reputation, employer and workplace, innovation, leadership and scale, and avoid-and-risk.

The same name carries opposite framings. Boeing appears in trust questions and in risk questions. In Perplexity's answer to "Which aerospace companies have lost the most public trust in recent years?", the answer placed Boeing first and described trust as having fallen most sharply there. Grok's answer on production delays also put Boeing first. Its answer on the commercial jet market, from Gemini, described Airbus as holding a leading position in deliveries and backlog.

Lockheed Martin leads where the question is about government work. It is the most-named brand in the government contracts and oversight group, just ahead of Boeing. Northrop Grumman leads the space and advanced-defense group. SpaceX is the most-named brand in the value-and-price group, though at a low share.

…whose public trust has fallen most sharply in recent years…
Perplexity, answering “Which aerospace companies have lost the most public trust in recent years?”

Who owns the answer, and why

Boeing was named in 667 of 1,250 answers, Lockheed Martin in 529, Northrop Grumman in 435, RTX in 393 and Airbus in 362. Boeing's lead holds across all five assistants, and Grok named it most often (181 of 250 answers). Claude and Perplexity named it least. L3Harris shows the same spread: Grok named it in 45 answers and Claude in 7.

Most of the credit tags on these answers are "Not Substantive". The brand is listed but not praised or faulted for anything specific. Where a substantive label does appear, the pattern is narrow. Boeing's most frequent was Safety & Compliance. Lockheed Martin, Northrop Grumman and RTX were each tagged most often for Financial Performance. Airbus was tagged most often for Reliability & Operations. Embraer's most frequent tag was Safety & Compliance.

Some names sit outside the tracked set. Claude and Gemini answers on autonomy and software modernization named Anduril, General Atomics, Palantir and Kratos. In the sampled answers, those firms surface mostly when the question is about new-style defense rather than established primes.

Boeing has struggled the most with production delays and ramp-up challenges among major aircraft makers over the last five years…
Grok, answering “Which aircraft makers have struggled most with production delays in the last five years?”

What the press is covering

In the 30-day PeakMetrics news index, SpaceX and Boeing have the largest volumes (51,777 and 47,588 mentions). The storylines differ. Boeing headlines cover the Navy F/A-XX selection, a Starliner discussion with NASA, a software glitch flagged on 737 MAX jets and a large Korean Air order. SpaceX headlines are mostly about its stock and IPO, including options volume and investor allegations.

Lockheed Martin coverage (17,283 mentions) centers on missile production agreements and PAC-3 work. Northrop Grumman's includes a large Army contract and stock-performance pieces. Airbus (23,392 mentions) is covered for A350F and A320neo supply-chain news, airline orders and a money-laundering case. Honeywell (15,608 mentions) headlines are dominated by securities class-action solicitations and its exit from the S&P 500.

RTX's news counts need care. Its recent headlines are about Nvidia RTX graphics cards and a crypto token, so its mention volume says little about the defense company. General Dynamics, L3Harris and Huntington Ingalls coverage leans heavily on stock-performance items from syndication-style sites.

Airbus has held a leading position in recent years…
Gemini, answering “What company dominates the commercial jet market right now?”

Where the two stories diverge

Volume in the press does not translate into presence in the answers. SpaceX has the most news mentions and the most headline mentions, yet it was named in 199 answers, well behind the big four primes. Honeywell has more than twice the news volume of Northrop Grumman, but the assistants named it in 68 answers against Northrop's 435.

The reverse is also visible. Northrop Grumman and Lockheed Martin appear in answers far more than their press volume would predict. The assistants seem to treat established primes as the standard answer to "which defense companies" questions, whatever this month's headlines say. Airbus has heavy press coverage and a steady but smaller answer footprint, and mainly shows up in reliability, safety and sustainability questions.

Boeing is the one brand where press volume and answer volume are both high. That does not mean the two narratives match. The press headlines in this window mix contract wins with software and program issues, while the answers lean on the trust, scrutiny and delay framing.

…no major contractor appears to consistently deliver defense programs under budget across the board…
Perplexity, answering “Are there any defense contractors that consistently come in under budget?”

What this means for comms teams

Press volume and answer presence are different measures, so track both. A company with heavy coverage may still be absent from the questions its stakeholders ask, and a quieter prime may be named constantly. Some answers also carry their own category noise, as with RTX.

The source mix explains part of this. In this snapshot, the most-cited domains were trade and owned sites (Simple Flying, Aviation Week, airbus.com, lockheedmartin.com), plus gao.gov, Wikipedia, Reuters and fool.com. By source type the split was Trade 36%, Owned 33%, Other 16% and News 14%. Company-owned pages are a real input, but so are oversight documents and trade reporting, which a comms team does not control.

Scrutiny questions draw on enforcement and litigation records. The ChatGPT answer on shareholder suits cited a litigation index, a legal site and an SEC filing. The Claude answer on export violations cited settlement figures. Teams facing legal or regulatory exposure should assume these records will surface in answers, and check what the public record says about the company.

How this was measured

Measured September 29, 2026. 250 unbranded questions per sector, asked to ChatGPT, Claude, Gemini, Perplexity and Grok on their product models, with web search on. Refreshed quarterly.

This is a snapshot, not a ranking or a trend: AI answers vary from run to run. It shows whether a brand appeared and which sources were cited, not how favorably it was described. The paid platform tracks favorability daily.

Full method

In an early five-question test, the same brand went from 40% to 30% to 70% visibility across three runs, which is why every figure here is dated and treated as a snapshot.

The questions cover 13 intents, such as reliability, value for money and customer service. A model drafted them, a review pass removed paraphrases and questions that point to one company, and every question was checked so that none names a measured brand. Each was asked once per assistant in run 2026Q4.

Every visibility figure comes with a 95% range (a Wilson interval). Where two brands' ranges overlap, treat them as tied. The figures use all 1,250 answers. The quotes in the story come from a stratified sample of 60 of them, spread across every assistant and intent.

Summarized on September 30, 2026from this snapshot's stored answers. Every quote is checked against the original answer.
