Management team
By working together we can utilise our strengths, exploit opportunities, mitigate risk and overcome the inevitable challenges far more effectively.

The Alliance Leadership Board
The Alliance Leadership Board (ALB) provides governance of the Alliance on behalf of the parties. It provides a forum for joint review of the Alliance Managing Director’s delivery against the overall Dreadnought Programme and for resolution of any issues between the parties.
The ALB has a representative from each of the three parties that are accountable in their own organisations for the Dreadnought Programme and other related programmes.
It is led by an Independent Chair, Sir Peter Gershon.
The Alliance Managing Director, Alex McMillan, leads an Alliance Management Committee responsible for driving delivery of the Programme to performance, time and cost, holding the three supplier organisations (Submarine Delivery Agency, BAE Systems and Rolls-Royce) to account for delivery of their work scope.

Steve Timms, Managing Director, Submarines
Steve was appointed Managing Director of BAE Systems Submarines from 1st March, 2021.
He brings to the role a strong track record of managing large-scale, complex defence programmes, having gained extensive experience in a wide and varied 41-year career with BAE Systems.
Having started as an apprentice in the Company’s Air sector, his career has seen him progress to a number of senior board level positions, where he has successfully led the delivery of several high-profile programmes, both in the UK and internationally.
Working across all aspects of a product’s lifecycle, from early phase concept design, into build and in-service, this experience culminated in being asked to lead the Submarines business.
It is an area of the business he was already familiar with having supported the Dreadnought programme in late 2017 and 2018 when he was Group Manufacturing Director, in the Company’s Chief Technology Office.
Before joining Submarines, Steve was the Managing Director of BAE Systems Naval Ships for 2 years. During that time he was responsible for building up the capability required to deliver the UK’s Offshore Patrol Vessel (OPV) programme, as well as overseeing the move from design into build of the Type 26 Global Combat Ship. The success of this programme had also led to international commitments from both the Australian and Canadian navies.
The majority of Steve’s career with BAE Systems has been spent in the Air sector, where as an apprentice he gained first-hand experience of the need to invest in and develop people. This has stayed with him throughout his career and proved valuable as he progressed to a number of senior positions, including on the Eurofighter Typhoon and international Hawk programmes.
Steve has a Master of Science (MSc) degree in Engineering Business Management from the University of Warwick. His contribution to the industry was recognised when he was made a Fellow of the Royal Aeronautical Society.
He is married with two children.
