The Elco 80 ft PT-109 is a gift rank II American motor torpedo boat with a battle rating of 1.7 (AB/RB/SB).

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.

Main article: AN-M2 (12.7 mm)

Two turrets with twin-mounted AN-M2 machine guns are had around the bridge area. Despite their full-flexible 360 degree traverse, limitations with the boat structure will severely restrict their fire angles against enemy boats.

Torpedo armament

The PT-109 is armed with four 21 in wet-heating Mk.8 torpedoes, which are mounted with two on the port side and two on the starboard side. Both are angled from the front and so requires angling to get onto target.

Pros and cons


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


  • 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 maneuvering to get a decent aim at a target in front


Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.
