The British Royal Navy's HMS Active, the second Type 31 frigate, was rolled out on February 24, 2026, at Rosyth shipyard, marking the end of its main construction phase. On the same day, steel cutting began for HMS Bulldog, the fourth ship in the series.

The Type 31 project aims to replace the Type 23 frigates, with all five ships expected to enter service by the end of the decade. The frigates will operate from Portsmouth Naval Base, supporting maritime security and operations alongside other Royal Navy vessels. The shipbuilding program supports 1,250 jobs at Rosyth and in the national supply chain.
