Rolls-Royce Submarines has formed a strategic partnership with INFINITY to develop advanced manufacturing capabilities for UK defence, adding a new industrial capacity theme ahead of the company's trading update on Thursday, November 12. Rolls-Royce announced the partnership on Friday, November 6, in a company press release.

INFINITY is developing a 200-acre technology park in Derby that will bring together full-scale prototyping, digital engineering, testing, validation, skills development and supply-chain collaboration. Rolls-Royce Submarines plans to work with INFINITY on capabilities including hot isostatic pressing, power-beam welding and additive manufacturing.

Manufacturing capacity supports defence growth

The planned facilities are intended to shorten development cycles, increase production capacity and reduce materials and unit costs. They are also designed to give Rolls-Royce greater control over the manufacture of large and strategically important components for defence, aerospace, fission and fusion applications.

Rolls-Royce said the partnership will allow its Raynesway site in Derby to focus on delivery while advanced manufacturing techniques are developed at purpose-built facilities. The submarine business designs, manufactures and supports the pressurised-water reactors that power the Royal Navy's submarine fleet. The wider technology-park project is estimated to create 17,500 skilled jobs in the East Midlands.

The announcement also points to demand connected with the UK's submarine programmes and Australia's future nuclear-powered submarines under the AUKUS agreement. It does not provide a direct revenue or profit forecast, so the near-term financial effect will depend on execution and on the trading update scheduled for the following day.

Trading update is the next catalyst

Rolls-Royce's investor relations calendar lists the trading update for 7am GMT on Thursday, November 12. Investors are likely to focus on operational progress, the outlook for civil aerospace and defence demand, and whether the company maintains its existing expectations.

Rolls-Royce stock traded at 15.82 euros on Lang & Schwarz at 11:53 CET on Wednesday, November 11, 2026.
