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 6.35 mm of hardened armour 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 6.35 mm sides and back with a 12.7 mm 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 106 km/h 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 quad-mounted 20 mm Oerlikon Mk.II turret aft and a single cannon at the front. They are extremely deadly to any targets (even some destroyers).
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 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 8,000 rounds for the two dual-mount 12.7 mm AN-M2 emplacements.
Additional armament
The PT-556 carries four Mk.13 torpedoes with 178 kg of explosives, which is pretty weak compared its counterparts from other countries. Still, it is still pack some punch to cripple enemy ship, and since you're carrying four torpedoes instead of two like other PT boats, these can be very helpful in case if you've missed a hit.
Usage in battles
The PT-556 is a PT boat that packed with heavy firepower in the form of 5 x 20 mm Oerlikon cannons and other supplementary armaments. As its nickname Thunderbolt suggests, the playstyle of this boat is strike hard and strike fast before retreating.
Due to the boat's poor survivability, speed and positioning is the key of success. Never rush into the enemy and instead utilizing covers or moving in pack with your teammates. In this way, you can provided heavy fire support on any distracted enemy.
Against destroyers, the PT-556 has no trouble to destroy them with four small torpedoes, albeit usually requires more than one hit to kill them. Thanks to your 4x Oerlikon turret, you can kill the enemy destroyer by engaging the ship from the sides, then spray your lead into every section the ship's side to wipe out the crew, this is more effective than concentrating on a single section.
Pros and cons
Pros:
- Main armament consists of five hard-hitting 20 mm Oerlikon cannons
- Rear 4 x 20 mm Oerlikon turret provided very dense cone of fire and capable of sinking destroyers without using torpedoes
- 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 to deal with armoured targets
- 37 mm AN-M4 rounds are pure HE or pure AP and no mix
Cons:
- 20 mm cannons have low velocity and awkward angle and therefore are hard to aim
- Very poor survivability
- Ammunition storage is next to the fuel tank
- Each individual torpedo is quite weak and often requires more than one hit to sunk enemy destroyer
- 37 mm gun is not accurate
History
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.
PT-556 was first assigned to Motor Torpedo Boat Squadron Twenty-Nine (MBTRon 29), under the command of CDR S. Stephen Daunis, USN. MBTRon 29 was assigned to the Mediterranean and was based at Calvi, Corsica, and later Leghorn, Italy. Operating under the British Coastal Forces, the squadron saw action along the northwestern coast of Italy and southern coast of France.
PT-556 was transferred to the Soviet Union on 12 April 1945, and was reclassified as TK-435. Her fate after transfer is unknown.
