Description

The Elco 80 ft, Thunderbolt (PT-556) is a premium rank III American motor torpedo boat with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.83 "Masters of the Sea" as part of the fleet release into Open Beta Test.

General info

Survivability and armour

Similar to the other Elco boats, the PT-556 has 6.35mm of hardened armor protecting the helmsman, who is a critical crew member. With a crew complement of 12 predominately operating guns above deck, this boat can be knocked out relatively easily. The quad Oerlikon mount on the rear features a protected "basket" with an open top, sporting the same 6.35mm sides and back with a 12.7mm front plate.

Mobility

This boat weighs as much as the heavier PT-565 while maintaining the top speed of the lighter PT-314, helping this boat live up to the nickname "Thunderbolt" which is scribed on the rear quad mount. With a top speed of 106km/hr in Arcade Battles, this boat is among the fastest in game. Additionally it sports a high reverse speed and is capable of tight turns.

Armament

Primary armament

The primary armament consists of a quadmounted 20mm Oerlikon Mk.II cannons aft and a single one at the front. They are extremely deadly to light targets and aircraft. Both turrets have fast traverse rate and good elevation angles so there should be no problem in engaging aircraft. Short bursts are all it should take to take out any unarmoured targets or aircraft. The ballistics should be familiar from the other PT boats. You should have some trigger discipline because you don't have enough ammunition to "spray and pray". The HE or universal ammunition belt should be used because of the general lack of armour around your battle rating.

The placement of the quad mount makes for a forward dead zone of roughly 20 degrees and roughly 45 degrees left and right of the bow. This can limit the ability to engage targets with maximum closing speed and maximum firepower at once.

Secondary armament

The secondary armament on this boat is one 37 mm AN-M4 cannon at the front of the boat. The low rate of fire and low velocity makes it unsuitable for general use but it can save you if your 20 mm cannons are taken out. It is unsuitable for anti-aircraft because of the problems mentioned above and the fact that it has poor elevation angles. The high explosive shells also self-destruct so you can't engage with them past medium ranges. The penetration rates of the armour-piercing shells are on par with the main Oerlikon cannons so you can have it as your backup for armoured targets.

Anti-aircraft armament

The PT-556 utilizes the same AA layout as the PT-565, however it does offer twice the ammunition load at 8000 rounds for the two dual-mount 12.7mm AN-M2 emplacements.

Torpedo armament

The torpedo armament is identical to the PT-565.

Pros and cons

Pros:

• Main armament consists of five hard-hitting 20 mm Oerlikon cannons
• Fast and agile as it is a motor boat
• Can carry 4 x torpedoes, 2 on each side
• AA defence consisting of 4 x 12.7 mm AN-M2 machine guns which provide enough protection
• 37 mm gun can be equipped with AP shells
• 37 mm AN-M4 rounds are pure HE or pure AP and no mix

Cons:

• 20 mm cannons have low velocity and therefore are hard to aim
• Is very prone to damage
• Ammunition storage next to fuel tank
• 37 mm gun is not accurate
• No 40 mm gun at this BR is an absolute disadvantage

PT-556 was an Elco 80-foot class Motor Torpedo Boat of the United States Navy. It was laid down by the Electric Launch Company (Elco) in Bayonne, NJ, on 1 July 1943. She was launched on 16 September 1943 and completed and commissioned on 20 October 1943.

PT-556 had a length of 80 ft, a beam of 20 ft 8 in, and a draft of 5 ft. The displacement was 56 tons and it was manned by a crew of 17. The ship was powered by three 1,500 shp Packard W-14 M2500 gasoline engines, turning three shafts; a speed of 41 knots could be achieved. The armament consisted of two twin .50 cal mounts (total of four machine guns), four 21 inch torpedoes, and one Elco Thunderbolt quadruple 20 mm mount (total of four 20 mm cannons). The PT-556 was one of the few torpedo boats to be equipped with the Elco Thunderbolt mount.
