The UK’s Defence Nuclear Enterprise (DNE) has made significant strides by successfully detaching the fin from the decommissioned submarine, Swiftsure, at Babcock’s Rosyth facilities in Scotland. As reported by the Ministry of Defence, this marks a groundbreaking achievement within the current dismantling initiative.

Swiftsure is on track to be the first Royal Navy submarine fully dismantled by 2026. To date, over 500 tonnes of conventional waste have been extracted from it, with most already recycled. The goal is aspiring: to recycle around 90% of its total weight.

This pioneering effort follows public consultations held in 2012 and 2015 and underscores DNE’s dedication to safe nuclear practices. By innovating disposal methods, the UK aims to set a standard for dismantling other submarines equipped with Pressurised Water Reactor 1 (PWR1) technology.Moreover, this project is not just about recycling; it also influences future submarine construction. Officials note that high-quality steel salvaged from decommissioned vessels is being repurposed for new submarines.

The fin removal was made possible through collaboration among various entities including DNE, Babcock, and Defence Equipment and Support’s Defence Recycling & Disposals Team (DRDT). Approximately 200 skilled workers are currently engaged in this dismantling process at Rosyth.

Scottish Secretary Ian Murray highlighted how this achievement intertwines national security with environmental stewardship within the UK’s nuclear strategy. He mentioned that just recently, prime Minister announced plans for up to twelve new nuclear-powered attack submarines as part of a £15 billion investment into Britain’s sovereign nuclear capabilities.

Sir Chris Gardner KBE, CEO of the Submarine delivery agency, expressed gratitude towards everyone involved in this milestone project while emphasizing its importance as a marker of progress.

Alistair Hughes from DRDT remarked on how effectively utilizing surplus assets can enhance resilience within defense supply chains while prioritizing national security and economic growth.

Additionally, the Submarine Dismantling Project plays an essential role in nurturing future talent within Britain’s nuclear workforce by offering hands-on experience to aspiring professionals.

With plans firmly set for completing Swiftsure’s full dismantlement by late 2026—fulfilling commitments made back in 2019—the project continues moving forward efficiently.
