The Experimental class sub-chaser PC-451 is a rank II American sub-chaser 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

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.

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


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.


Primary armament

Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}.

Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.

Secondary armament

Some ships are fitted with weapons of various calibres. Secondary armament is defined by the weapon chosen with the control Select secondary weapon. Evaluate the secondary armament and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that anti-air armament, even heavy calibre weapons, belong in the next section.

If there is no secondary armament, remove this section.

Anti-aircraft armament

An important part of the ship’s armament responsible for air raid defense. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship’s anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets.

If there is no anti-aircraft artillery, remove this section.

Torpedo armament

Many ships are armed with torpedo launchers, and for some vessels such as boats, torpedoes are an extremely important means of defeating an opponent. Evaluate the position of the torpedo launchers, discuss the ammunition available, firing specifics such as dead zones, features of the torpedoes themselves, etc.

If there is no torpedo armament, remove this section.

Special armament

Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can be an unexpected surprise for an opponent. Evaluate the ammunition of this type of armament and rate its performance in combat.

Usage in battles

This ship is an excellent vehicle even in an uptier compared to other US boats due to the steel armour, 20 mm secondary armaments, and a 76 mm cannon able to knock out a a PT boat. Though the armour is good enough against even a small crowd of PT boats, larger ships with bigger guns could still destroy the PC-451 with ease.

During a match, the 165 ft PC-451 is best used somewhat during the middle or towards the end of a match as the second or third spawn. The number of players attempting to torpedo will go down, while planes will start spawning in. Using the secondary weapons, the PC-451 can bring down multiple enemies and rack up points. However, dedicated and skilled pilots can still get a drop on the PC-451 if left unattended with all of the PC-451's firepower.

In terms of shell selection for the main armament, which consists of Fuse, HE, and APHE, bring Fuse and HE during downtiers as the HE can cripple boats easily while the Fuse can be used to target aircraft, adding the main armament into the defensive network the 20 mm secondaries provide already. In uptiers, HE and AP are recommended for dealing with more persistent boats. While destroyers could be damaged with the HE, anything further than 3 km away should be engaged with the AP shell in order to penetrate through armour.

Pros and cons


  • The 3-inch gun is powerful for its rank
  • Powerful AA defense
  • First US ship to receive all-out steel armour


  • Not very fast
  • 3-inch gun can be difficult to master for newer players


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.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
