About the company

Booz Allen builds and runs technology for the U.S. government, mostly for the military and intelligence agencies, and its engineers work alongside consultants who know each agency's mission. In 1958, it helped the U.S. Navy create PERT, a project-scheduling method first used on the Polaris submarine missile program and later adopted across government and industry. Its teams design cyber defenses, AI and data tools, and battlefield communications, and it sells its own products, such as Vellox, a suite of AI tools that spot and fight off hackers. Agencies pay mainly through multi-year contracts that reimburse costs, bill hours, or set a fixed price. Booz Allen was founded in 1914 and is based in McLean, Virginia.

PDW integrates Booz Allen mission autonomy software on AM drones with secure fleet updates

Performance Drone Works announced it is integrating Booz Allen's mission autonomy software, powered by Shield AI's Hivemind, onto its AM drones. The software enables autonomy-assisted missions whilst operators retain decision-making authority. PDW is also deploying Booz Allen's secure over-the-air fleet update system across its aircraft portfolio. The combined product entered testing on 30 September and is planned for general availability in Q1 2027. PDW aims to extend the autonomy software to its C100 aircraft later in 2027. The integration supports PDW's strategy to rapidly field and adapt systems. The company's Huntsville facility has annual production capacity of 100,000 drones. Booz Allen's update system is designed to reduce approved update cycles from weeks to hours, even in contested environments.

Aventra raises $17.5M for high-altitude balloon-dropped glide bombs

Virginia-based startup Aventra has raised $17.5 million in new funding, with Konvoy Ventures leading the round. Seed round backer Lavrock Ventures participated alongside new investors Booz Allen Ventures, Sands Capital, Langford Industries, and Western Alliance Bank. The company manufactures Piranha, a high-altitude balloon-dropped glide bomb that converts unguided munitions into precision-guided weapons. Since emerging from stealth with a $3.5 million seed round last October, Aventra has delivered over 400 units to US and NATO customers and doubled its production revenue. The system launches munitions from 60,000 feet and can glide approximately 100 miles, with recent demonstrations achieving accuracy within three metres of targets. Aventra plans to use the funding to scale production from 35 units monthly to 500 through a new Virginia facility called Factory Zero.

Palantir, Nvidia, Booz Allen restrict Anthropic and OpenAI models over data retention concerns

Palantir Technologies, Nvidia, and Booz Allen Hamilton are restricting use of AI models from Anthropic and OpenAI over data protection concerns, Reuters reported. The companies worry model providers could retain or extract value from sensitive corporate information. Palantir has pressed Anthropic for zero data retention guarantees. Nvidia limits Anthropic's models to less sensitive tasks, favouring its own Nemotron models for proprietary work. Booz Allen has banned staff from using Anthropic's commercial model on cybersecurity projects involving proprietary data. The pushback intensified after Anthropic introduced a 30-day data retention policy in June for its Claude 3.5 model, citing security monitoring needs. Anthropic responded by launching Enterprise Frontier Safeguards, allowing customers to store activity data in their own cloud infrastructure under their encryption keys.
