HMS Queen Elizabeth Aircraft Carrier Build (Final Assembly)

Rosyth Dockyard, Fife, Scotland, UK (final assembly) · 2009–2014 (construction), 2017 (sea trials) · £6.1bn (programme cost for two carriers), £3bn (unit cost for HMS Queen Elizabeth)

The judgement call

Account-gated at launch

The modular construction approach, with sections built across different UK shipyards, was a key strategy to distribute work and leverage national shipbuilding capabilities. - The project faced significant cost increases and delays, highlighting the inherent challenges in large-scale, cutting-edge naval procurement. - The carrier provides a four-acre military operating base deployable worldwide, significantly enhancing the UK's global power projection capabilities. - Lessons learned from HMS Queen Elizabeth's construction and initial operations have informed subsequent naval projects and maintenance strategies.

Key engineering challenges

Managing the complex logistics of constructing large sections of the carrier at multiple shipyards across the UK and transporting them to Rosyth for final assembly. - Integrating numerous complex systems, including propulsion, power generation, and aircraft handling equipment, into a single vessel. - Overcoming technical issues and ensuring the structural integrity and operational capability of the largest warships ever built for the Royal Navy. - Coordinating a vast workforce and supply chain across the entire project lifecycle.
