Rolls-Royce will receive up to 1.25 billion in UK government support to develop and build its UltraFan engine in Britain. The engine targets the short-haul aircraft market. The company plans to invest 2.5 billion in the programme over the next decade. It also intends to create 3,300 UK roles by 2029. Public funding does not remove technical and commercial risks. The engine must still meet performance, reliability and certification requirements, and win customers. Rolls-Royce's civil aerospace and Power Systems businesses remain central to its growth. Cost control, supply chain pressure and cash generation will shape the returns.

HM Treasury is adding £120 million to the UK's Sovereign AI Fund, which backs domestic AI startups. Half will go into direct investments in UK AI companies, and half into the Sovereign AI R&D Procurement Scheme. The Fund rises to £560 million, and the procurement scheme grows from £100 million to £160 million. The Fund now also targets physical and industrial AI, including robotics, autonomous systems, and advanced manufacturing. Under the scheme, the government acts as an early customer rather than a grant funder. Firms build the technology, departments trial it, and successful firms keep their IP. The money is part of a £621 million AI package announced on October 24, days before the Chancellor's Budget on October 28.

The UK has announced £100 million ($134 million) for an AI Biosecurity Lab, which OpenAI, Anthropic, and Google DeepMind will support. The funding is part of a package of measures to help the government understand and tackle the risks posed by the technology.
