-The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} Soviet motor gun boat {{Battle-rating}}. It was introduced during [[Update "Apex Predators"]] as a reward for [[Battle Pass: Season X, "Royal Guard"]].
+The '''{{Specs|name}}''' (NATO: P-6) was the non-standard Project 183 PT boat (AKA P-6 in NATO code) exported to Egypt with its rear-turret and torpedoes removed for the installation of a BM-21 MLRS, likely to be an improvised solution during the Six-Day War as a mean to bombard Israeli forces from the coastal waters. The major difference between the Pr.183 and the Pr.183 BM-21 is the BM-21 Grad 122 mm MLRS launcher on the aft platform in place of the turret; as well as a new radar replacing the original, dome-like one.

The 40 rockets onboard will make sure light vessels will meet a swift end from the bombardment of 122 mm rockets from distance.
+Introduced during [[Update "Apex Predators"]] as a reward for [[Battle Pass: Season X, "Royal Guard"]]; although the installation of BM-21 MLRS costed the aft autocannon turret and the torpedo tubes, thus halved its firepower against light vessels, there are forty 122 mm rockets now sits right at the aft and now players can utilize this infamous "Hailstone (Grad)" to bombard even destroyers with salvos; do remember to take cover from time to time to maximize the efficiency of this vessel.

 A common characteristic of PT boats is their rather unprotected hull and superstructure, this is especially true for Pr.183 due to the size and weight limits for PT boats. The ship only has 10 mm of wood for the hull and 4 mm steel for turret and command tower, anything larger than .30 calibre has very high odds to penetrate the ship itself, let alone direct hits from cannons. So staying away from heated battlefield is extremely crucial for its survival. This also being limited by the rather small crew pool at only 16 crews onboard; chances are the ship might still be afloat but the crews will be knocked-out instead.
-The Egyptian Navy removed the aft twin 25 mm autocannon turret and torpedo tubes onboard, and installed a BM-21 MLRS instead. The weapon itself, a single 122 mm rocket projectile with 10 kg of TNTe, is certainly a nightmare for light ships as this will likely mean a knock-out for them, larger ships up to destroyers could even fall victim of it as it has a 40-shot salvo and this could trigger extensive damage to either exposed components or overpressurizing turrets, disabling the ship or even sinking them straight. Although having one less autocannon turret from its base model, the remaining 2M-3 twin mount 25 mm autocannon has rather high penetration for its calibre and 120 shots per magazine can also make sure it can cause havoc to unnoticed ships that showed their sides or ships with rear-mounted weaponry. To make sure the maximum efficiency of the ship, it is suggested to play it as a "guerrilla-on-water" where players can utilize its sufficient mobility to manoeuvre around inland channels where it can take cover behind terrain, then strike out for a sudden attack for enemy ships; alternatively taking cover and use the rockets for taking down unnoticed enemies. Making it a small yet formidable enemy to be dealt with.

-During the Nasir, the President of Egypt at the time, was still on the chair, the country saw better relationship with the Soviet Union which the latter provided a large amount of aids and military equipment ranging from assault rifles up to jet fighters, the abundant Project 183 was also among one of the sales to Egypt with around 46 of them delivered to their navy.

-Commonly known as the "Grad" (Hailstone), the 122 mm BM-21 rockets, which are one of the most common export Soviet weapons, are now installed as a MLRS on Pr.183 instead of being on Ural trucks; the launcher itself could traverse 360° thanks to its clearance to the superstructure. While the original intention of MLRS on an attack boat is purely for coastal bombardments against enemy ground targets, if enemy boats or auxiliary ships i.e minelayers or destroyer escorts are within its range, all the 40 rockets onboard with almost 10 kg TNT equivalent of explosive contents will certainly give them a bad day, either from being detonated on impact or critically damaged by the salvo.

-But there not only bad news for the ship, while Egyptian removed a twin 25 mm autocannon turret and torpedo tubes onboard, they installed a BM-21 MLRS instead; the weapon itself has been famous of being the hailstone of Soviet/Warsaw Pact countries with large coverage to grouped targets, but firing them separately is also viable and this will be the case for Pr.183. A single 122 mm rocket projectile with 10 kg of TNT equivalent explosives is certainly a nightmare for light ships as this will mean a likely one-hit-kill for them, larger ships up to destroyers could even fall victim of it as it has a 40-shot salvo and this could trigger extensive damages to either exposed components or overpressuring turrets, disabling the ship or even send them straight to the Davy Jone's chest. Although having one less autocannon turret from its base model, the remaining 2M-3 twin mount 25 mm autocannon has rather high penetration for its caliber and 120 shots per load can also make sure it can cause havoc to unnoticed ships that showed their sides or ships with rear-mounted weaponry. To make sure the maximum efficiency of the ship, it is suggested to play it as a "guerrilla-on-water" where players can utilize its sufficient mobility to maneuver around inland channels where it can take cover behind terrain, then strike out for a sudden attack for enemy ships; alternatively taking cover and use the rockets for taking down unnoticed enemies. Making it a small yet formidable enemy to be dealt with.

-The overall dimension of this variant of Project 183 is identical to its counterpart in tech-tree, while both are called by this name, the major difference of Egyptian boats is a rectangular box on the aft of the boat- which upon closer inspection is in fact a BM-21 Grad 122 mm MLRS straight from its land-based cousins; as well as a new radar (albeit being aesthetic than operable) replacing the original, dome-like one.

To say at least: for most of the time, anything that is larger than rifle caliber will have no problem penetrating the mere 4 mm of steel, let alone the hull itself with only 10 mm; this also means that a near-miss from higher caliber cannons can do serious damage to the ship itself.
