Hi Folks, think there is a bit of a mix up here! What Cpt. Cormorant seems to be building is the Coastal Patrol Craft introduced in 1970, and subsequently transferred to the Police Coast Guard, where they have long since been replaced. The boat in Cormorants pic was commissioned in 1971. See pic from RSN official site - History.

They were a Vosper design, based on the 110footer, first boats built in UK the rest in Singapore.
John: the class you are talking about is actually the 'Fearless' Class.
RSS independence being pennant number 87. They were built by ST Marine (Singapore Technologies) and commissioned from 96 (Fearless) to 98 (Independence). Pic 2 is of one of them, RSS Resilience.
This class is now being replaced by 8 ships ( independence-class littoral mission vessels) being built by ST Engineering. Our company helped ST with the integrated Comms System design for both these classes!
RSS independence pennant number 15 (replacing #87 as you say John) is the only one currently in service. This info may not unfortunately get Cormorant much further but maybe it'll help prevent chasing wild geese! Cheers 😎
