The Experimental class sub-chaser PC-451 is a rank I American sub-chaser with a battle rating of 2.0 (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 PC-451 is the first ship in the USA line to gain all-round steel armor protection, with between 5-8 millimeters or protection on all areas. This allows the ship to be mostly immune to .50 fire and under, while also giving good protection against 20mm fire when angled well. However, when not angled those shells will have no problem penetrating through.


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

The PC-451's primary armament is a 3-inch cannon which gives it considerable stopping power. Well placed shots can disable smaller craft with ease and do major damage to larger ships. Use the HE shells when facing lower ranked enemies, and the AP shells when up-tiered. The HE-VT shells can be effective against aircraft while being used as mini HE shells, but using them in that fashion is not ideal.

Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}.

Secondary armament

The PC-41 is armed with a large amount of 20mm Oerlikons , some in twin mounts and some in single mounts. These double as both AA weapons and a secondary armament and are capable of punching through most armor. Use the default belts, due to their equal mix of AP and HE shells. The AP shells give them a good amount of penetrating power, enough to pierce most armor at your BR, while keeping enough HE to deal with lighter targets.

Special armament

The PC-451 is armed with both depth charges and charge mortars. With enough daring, one can use them to give a huge punch to other vessels, but they will more likely be hit by fire and damage your ship. It is not recommended to take them unless you believe you can use them effectively.

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.
