Looking at the table in this report (https://www.navylookout.com/progress-re ... -frigates/)
(as of 2020)
- Frigate LIFEX start / end / Out of service date
HMS Argyll 2015 / Feb 2017 / 2023
HMS Montrose 2015 / July 2017 / 2027
- Monmonth was lost, yes
- but Montrose was NOT lost, just changed her name as HMS Argyll, so to say?
Better than we thought, I guess.
