HMS Active launched as the Royal Navy’s second Type 31 frigate

In the latest step in its surface fleet modernisation plans, the Royal Navy has launched HMS Active, the second of its new Type 31 frigates, marking a key milestone in bringing these ships into service. The vessel was floated out at Rosyth through a complex operation carried out entirely within the shipyard, underlining the growing industrial capability behind this ambitious programme.

Launch operation at Rosyth for HMS Active

The launch process required a carefully controlled move in which the ship was transferred from the assembly hall using a self-propelled modular transporter. The unit was then set onto a semi-submersible barge, from which the float-off operation was conducted, allowing the hull to enter the water for the first time.

HMS Active and the Type 31 launch method compared with HMS Venturer

Unlike the first ship of the class, HMS Venturer-which was launched in open water in the Forth estuary before being towed back to the yard-HMS Active followed a different approach. For this launch, the barge was submerged inside Rosyth’s large dock, a choice that significantly cut the time, cost and logistical complexity associated with conducting the operation at sea.

Royal Navy and DE&S support, with procedures shared with Type 26

Throughout the manoeuvre, engineers from the Royal Navy and Defence Equipment & Support (DE&S) provided technical assistance to ensure the process was executed correctly. It is also worth noting that the same type of barge is used on the Type 26 frigate programme, reflecting an increasing standardisation of procedures across the UK naval shipbuilding sector.

With the launch complete, HMS Active will now move into its final fitting-out phase, including systems installation, trials and subsequent commissioning. The Royal Navy emphasised the importance of fielding state-of-the-art ships in an increasingly demanding strategic environment.
