Elco 80 ft PT-109
The Elco 80 ft PT-109 is a gift rank II American motor torpedo boat with a battle rating of 2.0 (AB/RB/SB). It 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".
Survivability and armour
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.
Write about the ship’s mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward speed and reverse speed.
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.

A single 20 mm Oerlikon cannon is mounted at the stern of the boat.

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.

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 get 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
- 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
