Description

The 89 ft PT-810 is a rank V American motor torpedo boat with a battle rating of 3.3 (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.

Mobility

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.

Armament

Primary armament

PT-810 has two 40 mm L/60 Bofors cannons which are a step above previous American torpedo boats. The cannons are arranged with one on the bow and the other on the stern so careful manoeuvring will be required to maintain both on a target. These are most effective when being used against small craft such as torpedo boats, motor gunboats, minesweepers and submarine chasers. In its BR class, it is possible to face larger threats including destroyers which will mostly be unharmed by this gunfire. Aircraft are also excellent targets and can be brought down with accurate fire.

The 40 mm L/60 Bofors Mark 3 cannon has access to three available belts:

• Universal: AP-T / HEFI-T / AP-T / HEFI-T
• HE: HEFI-T / HEFI-T / HEFI-T / AP-T
• AP: AP-T / AP-T / AP-T / HEFI-T

Some of the more heavily armoured gunboats, such as the Russian ones, will be immune to the 40 mm HE shells so it may be wise to be a belt of AP. Against aircraft, HE is the most optimal choice. Otherwise, the Universal belt provides a good balance against most targets.

Secondary armament

For secondary armament, PT-810 has a pair of twin 20 mm Oerlikon Mk.II cannons. These are grouped amidships with one of the mounts being next to the bridge in an elevated position which gives it clear angles of fire, with the other being on the deck just behind the bridge. They can serve as closer range anti-aircraft defenses as well as targeting small boats that are in close proximity. The range on these cannons is limited, so be aware that their use will be restricted to close quarters combat.

The 20 mm Oerlikon Mk.II cannon has access to three available belts:

• Universal: HEF-T / HEF-I / AP-T
• HE: HEF-T / HEF-I / AP-T / HEF-I
• AP: AP-T / AP-T / AP-T / HEF-I

The Universal or HE belts are generally the most effective choices for the 20 mm Oerlikons, as anything that has substantial armour will be able to defeat even the 20 mm AP shells. The HE belts will also give the best effectiveness against aircraft.

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

While the torpedoes on the PT-810 may be smaller than previous torpedo boats, they are very dangerous and can be highly effective if used correctly. The 21" (53.3 cm) Mark 16 is a high-performance torpedo with short-range but excellent speed. While the distance travelled is only 6,400 meters they have a speed of 46 knots (85 km/h) which is only slightly slower than some other small craft. In addition, the warhead is formed out of 572 kg of Torpex which gives it a TNT equivalence of 915.2 kg. This is nearly as destructive as the most powerful Japanese torpedo, the Type 93 Model 3. Due to the restricted range, and no modification to increase it at the expense of speed, this makes the Mark 16 an ambush torpedo. If the torpedoes are used carefully and aimed properly, it is possible to take out multiple large vessels with a single salvo.

Special armament

PT-810 has a dedicated 81 mm Mark 2 mortar on the starboard (right) side just aside the bridge. This can either be aimed manually by selecting it or it will fire automatically. The mortar fires the M43A1 HE shell only, and as it is a mortar the shell has an extremely ballistic arc with a very low muzzle velocity (254 m/s) which makes targeting difficult.

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

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".
