General info

Survivability and armour

Armourfront / side / back
Hull8 mm (steel)
Superstructure4 mm (steel)
Number of section5
Displacement374 t
Crew46 people

The PC-451 is the first ship in the USA line to gain all-round steel armour protection, with between 5-8 mm of protection on all areas. This allows the ship to be mostly immune to .50 cal fire and under, while also giving good protection against 20 mm fire when angled well. However, when not angled those shells will have no problem penetrating through.

Mobility

Speedforward / back
AB62 / 27 km/h
RB41 / 18 km/h

Without any upgrades purchased, the PC-451 has a top speed of 35 km/h in RB (45 km/h in AB). While being a lighter and more nimble vessel than other larger ships like destroyers, players must still be aware that the PC-451 will need some time to make a full stop in the water, as it is a heavy ship for its class, weighing in at about 374 tons. The ship has very good mobility considering its overall characteristics. It is advised that players plan out their movements thoroughly with the PC-451 to get the most out of its mobility, as it is a heavier ship.

Armament

Primary armament

Turret3-inch Mark 10 cannon
Ammunition100 rounds
Vertical guidance-10° / 85°

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.

Secondary armament

2 х Turret20 mm/70 Oerlikon Mk.II autocannon
Ammunition1800 rounds
Belt capacity60 rounds
Fire rate450 shots/min
2 х Turret2 x 20 mm/70 Oerlikon Mark V autocannon
Ammunition3600 rounds
Belt capacity60 rounds
Fire rate450 shots/min

The PC-41 is armed with a large amount of 20 mm Oerlikon cannons, 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 armour. 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 armour at your battle rating, while keeping enough HE to deal with lighter targets.

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 hull, 20 mm secondary armaments, and a 76 mm cannon able to knock out a PT boat. Though the steel hull 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 PC-451 is best used somewhat during the middle or towards the end of a match as the second or third spawn, and not rush into hot zones. It is best to angle into the zone where more of your guns can engage than straight in.

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 the PC-451's firepower.

In terms of shell selection for the main armament, which consists of HE, HE-VT (variable time-fused), 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

Pros:

  • The 3-inch gun is powerful for its rank
  • Powerful AA defence
  • First US ship to receive all-out steel hull with some armour
  • The main 3-inch gun has access to HE-VT rounds, useful for targeting aircraft at range
  • 46 crew members, more durable

Cons:

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

History

PC-451 was an experimental submarine-chaser class. It was laid down on September 28, 1939 as Hull No.166, by DeFoe Boat and Motor Works, Bay City, Michigan. It was built as a part of the Experimental Small Craft program of 17 May 1938. The ships were called X-boats, and were classified as 165 footers, but the ships had differing characteristics. It was launched on May 23, 1940, and was commissioned on August 12, 1940 as the USS PC-451. It was assigned to the East Coast of the United States. The ship sank the American tug Nancy Moran off the eastern coast of Florida on December 26, 1941 by ramming, likely by accident. The USS PC-451 was decommissioned on December 2, 1945, and was struck from the Naval Register on January 8, 1946. It was transferred to the Maritime Commission in January 1947, to be disposed of. It is unknown what happened to the ship after that point.

The ship had a displacement of 374 t, a length of 163 ft, and a beam of 20 ft 9 in. It was powered by two 2,880 bhp General Motors 16-258S diesel engines, two General Motors 6-233A diesel engines, and Farrel-Birmingham 75 kw generator sets. It had a single reduction gear and two shafts. The armament consisted of two 3"/50 dual-purpose mounts, two twin 20 mm mounts, two single 20 mm mounts, two Mk 20 Mousetrap projectors, two k-gun depth charge projectors and two depth charge racks. The crew complement was 65 sailors and officers, and the maximum speed was 18.8 knots.
