Type 31 Frigate

The Type 31 frigate (also known as the General Purpose Frigate (GPFF) and Fearless-class) is a class of ten frigates for the Royal Navy that entered service in the 2020s to complement the more capable Type 26 frigates. In 2018, three designs were selected for the competitive design phase:

• BAe Systems/Cammell Laird with the Leander design based on the Khareef-class corvettes.
• Babcock/BMT/Thales with their Arrowhead 140 design based on the Iver Huitfeldt-class.
• Atlas Elektronik UK/Thyssenkrup Marine Systems with a design based on the MEKO A-200.

In September 2019, it was announced that Babcock’s Arrowhead 140 design had been selected for the Type 31 frigate.
