<!--''In the first part of the description, cover the history of the ship’s creation and military application. In the second part, tell the reader about using this ship in the game. Add a screenshot. If a beginner player has a hard time remembering vehicles by name, a picture will help them understand which ship is being discussed.''-->

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American motor torpedo boat {{Battle-rating|1}}. It was introduced in [[Update 1.79 "Project X"]] as part of the fleet closed beta test.

=== Survivability and armour ===
 +
<!--Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armament separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Tips for preserving survivability should be saved for the "Use in battle" section.

All of the other templates can be found in the [[:Category:Templates]] and its sub-categories.

If necessary, use a graphic template to show the most well-protected or most vulnerable points in the armour.-->

The 77 ft PT-20 has no areas with serious amounts of armour protection. The hull of the vessel consists of 40 mm thick ship wood and the bridge on top is made of 15 mm ship wood. Any projectile that hits ''will'' penetrate and deal damage including fragmentation and splash damage from nearby shells. The crew is 15 people which is about average for the PT-20's BR, although any prolonged engagement will likely end in destruction through the loss of the crew. The PT-20 has a total of 4 compartments, 3 for the hull and one for the bridge. The second section of the hull houses the fuel tanks and the third contains the three engines. Damage to the middle of the ship will often set fires or disable the mobility of the PT-20.

The 77 ft PT-20 is a very quick and agile vessel and is able to reach its top speed in under 15 seconds from a stopped position. A 180° turn can be performed in about 10 seconds when started at full speed, and a complete loop can be made in under 20 seconds. Half rudder deflection is achieved in 2 seconds and maximum deflection in around 10 seconds.

Important to note is the fact that the main armament is unable to aim at targets on the water directly ahead due to the turrets being located just behind the bridge. Off to the side of the vessel, it is possible to aim one or both of the turrets and directly astern it is possible to use both.

This boat is difficult to play. The optimal position to maximize your survivability is to have your bow pointing directly at your enemy however that also means you have no guns to fire at them. The optimal position for your guns is to have your rear point at the enemy but it exposes 3 of the 4 sections of the boat(particularly when driving forward at a high speed).

The 77 ft PT-20 was a follow-on to the first serial production PT boats in the United States, the Elco 70 ft PT-10 series. The PT-20 series was longer and heavier than their predecessors which caused a reduction in speed, although they were given additional torpedo tubes in an effort to increase the firepower. The change to 21 inch (53.3 cm) torpedo tubes up from 18 inch (45.7 cm) was a large addition to weight, and the earlier 70 ft PT boats could not carry the desired amount of torpedo tubes. In late 1941 and early 1942 a total of around 50 of these 77 ft Elco PT boats were produced and these would form the basis for the other widely produced versions such as the Elco 80 ft PT-103.

Description

GarageImage PT-20.jpg


The Elco 77 ft PT-20 is a rank I American motor torpedo boat with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.79 "Project X" as part of the fleet closed beta test.

General info

Survivability and armour

The 77 ft PT-20 has no areas with serious amounts of armour protection. The hull of the vessel consists of 40 mm thick ship wood and the bridge on top is made of 15 mm ship wood. Any projectile that hits will penetrate and deal damage including fragmentation and splash damage from nearby shells. The crew is 15 people which is about average for the PT-20's BR, although any prolonged engagement will likely end in destruction through the loss of the crew. The PT-20 has a total of 4 compartments, 3 for the hull and one for the bridge. The second section of the hull houses the fuel tanks and the third contains the three engines. Damage to the middle of the ship will often set fires or disable the mobility of the PT-20.

Realistic/Simulator 65 76

The 77 ft PT-20 is a very quick and agile vessel and is able to reach its top speed in under 15 seconds from a stopped position. A 180° turn can be performed in about 10 seconds when started at full speed, and a complete loop can be made in under 20 seconds. Half rudder deflection is achieved in 2 seconds and maximum deflection in around 10 seconds.

Armament

Primary armament

Main article: AN-M2 (12.7 mm)
2x 12.7 mm AN-M2 (x2)
Turrets
Port Turret Starboard Turret
Vertical guidance -5°/+65° -5°/+65°
Horizontal guidance ±180° ±180°
Ammo capacity 9,600
Rounds per turret 4,800

Important to note is the fact that the main armament is unable to aim at targets on the water directly ahead due to the turrets being located just behind the bridge. Off to the side of the vessel, it is possible to aim one or both of the turrets and directly astern it is possible to use both.

The recommend belt to use is the APIT belt. It suffers from a slight penetration penalty compare to AP but gain the ability to set fires.

Usage in battles

This boat is difficult to play. The optimal position to maximize your survivability is to have your bow pointing directly at your enemy however that also means you have no guns to fire at them. The optimal position for your guns is to have your rear point at the enemy but it exposes 3 of the 4 sections of the boat(particularly when driving forward at a high speed).

It is recommend you engage enemies by driving directly at them, releasing your torpedoes, then do a 180 and either use your machine guns to fight or smokes to run away.

Other players that prefer to play less aggressively just play the boat constantly in reverse so they can always have guns to fire 'forwards'. Another variant of this playstyle is camping behind an island with all four guns pointed at a high traffic area.

Some players attempt to play the boat as an AA gun but it lacks the vertical elevation to engage planes directly above it and the survivability to take on strafing fighters.

Pros and cons

Pros:

  • .50 calibre machine guns can effectively deal with just about any opponent it faces.
  • The 21-inch torpedoes can instantly obliterate an enemy ship, given they hit their mark.
  • Decent top speed and acceleration

Cons:

  • .50 cal turrets cannot face forward
  • The arrangement of the torpedoes requires firing from an angle against an enemy.
  • Wooden ship with no armor

History
