RTX

RTX Corporation (formerly Raytheon Technologies, rebranded RTX in 2023) is one of the largest US defense and aerospace contractors across its three operating businesses — Collins Aerospace (commercial-aviation systems and components), Pratt & Whitney (commercial and military jet engines), and Raytheon (missiles, defense electronics, integrated air-and-missile-defense, command-and-control). The current company was formed from the 2020 merger of Raytheon Company (founded 1922 in Cambridge, Massachusetts) and the aerospace businesses of United Technologies Corporation (Pratt & Whitney, Collins Aerospace, Otis, Carrier — with Otis and Carrier spun off as separate publicly-traded companies before the merger). RTX trades on NYSE as RTX and employs approximately 185,000 workers globally — among the largest US-headquartered manufacturer-employee counts.

Pratt & Whitney is one of the three dominant commercial-jet-engine manufacturers globally (alongside GE Aerospace and the CFM International joint venture between GE Aerospace and Safran). Pratt's GTF (geared turbofan) engine family powers significant fractions of the Airbus A220 and A320neo fleets. Collins Aerospace provides cabin interiors, avionics, mission systems, and structural components across most major commercial-aircraft platforms. Raytheon's product portfolio includes the Patriot missile-defense system, NASAMS, AMRAAM air-to-air missiles, Tomahawk cruise missile, and the SPY-6 naval radar — Raytheon's missile production has been particularly stretched post-Russia's invasion of Ukraine, with the Patriot, NASAMS, AMRAAM, and Stinger missiles all in extreme demand from US and allied militaries.

RTX's AI strategy spans defense and commercial-aviation applications. Pratt & Whitney's engine-data analytics business uses ML extensively for predictive maintenance and fuel-efficiency optimization. Collins Aerospace integrates AI into avionics and mission-systems products. Raytheon's defense AI applications include sensor-fusion (the SPY-6 radar uses extensive ML for target classification), missile-guidance optimization, and integrated air-and-missile-defense command-and-control. The 2024 Raytheon partnerships with Anthropic Claude and the broader DoD AI-procurement landscape position the company as both a system integrator for AI-foundation-model deployments and an in-house AI capability provider for legacy defense platforms. RTX's scale across both commercial-aviation and defense gives it a uniquely broad AI-deployment surface compared to peers.

RTX (Raytheon) is among the interceptor and command-and-control contractors selected for the US “Golden Dome” homeland missile-defense program.
