Story
PT-502 Rose, the long arm of the Corvettes. This ship is made from the hull of the PT-501 Jasmine. The original design lack weapon range and overall effectiveness, only relying on short range 14.5 mm guns for air defense. The soon-to-be captain, Rose, asked the ship to be rearmed fully with proximity fused cannons. This new air defense system boosts combat capability exponentially. She also trained an elite squad of gunners to man them.
