Another Vanguard, half-sister of Taiwan Straits - armor scheme different as new armor had to be manufactured for the ship. Named after another victorious battle - getting rid of the Portuguese Communist fleet (of some torpedo and gunboats) at the namesake location. Small victory, but at least the navy could show that up - and no need to name the ship after army generals or land battles.
