General info

Survivability and armour

Armourfront / side / back
Hull40 mm (wood)
Superstructure15 mm (wood)
Number of section3
Displacement38 t
Crew12 people

The hull structure of the boat has no armour at all. The only armour present on this boat is the bridge that contains 6 mm of antifragmentation armour, and the 13 mm rolled homogeneous armour of the 20 mm mount.

Most of the front hull is open space and so there are not critical components that could be hit if rounds come in across at the front end. However, from the bridge on backwards is the engine, ammo, torpedoes, and fuel all scattered around that could be easily hit, ignited, or detonated.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Pros:

  • Slender PT boat profile
  • Quite speedy at flank speed
  • Open space in front could let some lucky shots pass through harmlessly

Cons:

  • Limits in gun traverse means, despite able to traverse 360 degree, there are many angles where only one turret could aim onto target
  • Both primary armaments are only able to be used on ship targets at ship starboard side
  • Torpedoes at each side are split at an angle, requires manoeuvring to get a decent aim at a target in front

History

Construction

PT-109 was laid down by Elco (Electric Launch Company) in Bayonne, New Jersey, on 4 March 1942. It was launched on 20 June 1942, delivered to the U.S. Navy on 10 July, and completed on 19 July.

Initial Service

Under the command of CDR Henry Farrow, USN, PT-109 was first attached to Motor Torpedo Boat Squadron FIVE (MTBRon5). MTBRon 5 was assigned to the Panama Sea Frontier beginning in September 1942. On 22 September 1942, PT-109 was transferred to MTBRon 2, with her new commanding officer LT George A. Brackett, USNR. MTBRon 2 was transferred to the South Pacific in 1942. There, the squadron took part in the Solomons campaign, fighting night actions against the Japanese Tokyo Express with the goal of defending the US-held Guadalcanal. MTBRon 2 was at Tulagi island on 23 April 1943, when LTJG John F. Kennedy took command of the PT-109.
