The PT-109 was perhaps one of the most famous PT boats among the USN torpedo boat fleet as the ship commanded by the would-be 35th POTUS, LTJG John F. Kennedy. The ship was ordered in 1942 as part of the fleet of USN's PT boats built by Elco at Bayonne, NJ and the 7th ship of the PT-103 variant. The ship was delivered to USN on July 1942, then transported to the Pacific battlefield soon in August before it finally joined battle in late December as part of the PT squadron on Tulagi of Solomon Islands by different crews and commander. JFK arrived at the Pacific by February 1943 in against his father, Joseph P. Kennedy Sr.'s will for safer navy positions away from the WWII, helming the boat since 23rd April, 1943, he participated in the night strikes against the Tokyo Express which was the bloodline of IJA/IJN forces at the Solomon Islands; however, after a dreadful action at Blackett Strait with USN PT fleet failed to hit IJN ships at night due to bad coordination on 1st August, 1943, his boat collided with IJN Amagiri at 02:27 on 2nd August and the subsequence explosion killed two of his crews; thanks to JFK's resilient and luck, the remaining eleven crew including himself managed to drift and swam onto the Plum Pudding Island (Now Kennedy Island) before they were rescued by scouts by the 8th August.

PT-109 was one of the earliest pre-orders offered to access the fleet closed beta test before being removed from the store with the wide-release of the closed beta test in Update 1.79 "Project X"; armed with its initial configuration of only twin mount .50 cal and only a Orelikon 20 mm autocannon onboard (the famous 37 mm AT gun was a field modification by the crew in 1943), the overall firepower have some flexibility against both small patrol boats or sometimes armored boats while players should be extra careful for its poor protection to avoid quick demise.
