The Portuguese Navy's second Bartolomeu Dias (M)-class frigate, NRP D Francisco de Almeida (F 334), is scheduled to begin its mid-life upgrade (MLU) in Den Helder, the Netherlands, on 6 July, the service has told Jane's.
Upgrade work, which will be carried out at the Royal Netherlands Navy's Marinebedrijf shipyard, is scheduled to be completed in April 2022.
First-of-class NRP Bartolomeu Dias (F 333) entered its MLU in May 2018 and work is expected to be completed in late 2020.
The modernisation of Portugal's two M-class ships in the Netherlands was approved in 2016 and aims to extend their service lives until 2035 as well as delivering capabilities to support the continued participation in higher-intensity national and multinational operations.
