Welcome a new Tech Tree line of mighty Polish tank destroyers! Research six powerful tanks spanning Tiers V–X, branching off the Tier IV 14TP.

While the vehicles in Tiers V–VII are classic turretless tank destroyers with traditional gameplay, the machines in Tier VIII and onwards feature the new Deep Rifling mechanic, which enhances their effectiveness in close-range engagements and rewards an aggressive playstyle.

Vehicles such as the SDP 60 Gonkiewicza and the NC 70 Błyskawica can be exceptionally powerful in close combat, delivering devastating firepower when it matters most.

SDP 40 Zadymka

• Nation: Poland
• Tier: V
• Class: Tank Destroyer
• Research Cost: 36,515 XP
• Purchase Cost: 360,000 Silver

The tank destroyer code-named SDP 40 Zadymka was designed with the goal of destroying heavily armored combat vehicles and reinforcing prospective medium tanks. The gun caliber was large enough for the vehicle to be used as an assault SPG. Its engineers drew on British experience in manufacturing hulls with large cast parts. Since the ammunition could not fit in the cabin, the solution was to make a niche partly covering the engine compartment. The work did not progress beyond schematic blueprints.

SDP 44 Burza

• Nation: Poland
• Tier: VI
• Class: Tank Destroyer
• Research Cost: 37,630 XP
• Purchase Cost: 920,000 Silver

In the pre-war period, Polish tank construction was developing along two lines. The first, somewhat influenced by the British school, was based on original technical solutions. The second was premised on French ideas—unsurprisingly, since the country was buying French tanks at the time. After the outbreak of World War II, some Polish designers left for Britain where they continued their work. One of their projects was the SDP 44 Burza tank destroyer, which had features typical of British assault tanks and proposals for the introduction of advanced technical solutions. However, after a while, the project was closed in favor of the A39 (Tortoise) assault tank.

SDP 57 Gowika

• Nation: Poland
• Tier: VII
• Class: Tank Destroyer
• Research Cost: 79,500 XP
• Purchase Cost: 1,490,000 Silver

After the end of World War II, the Polish Army operated Soviet self-propelled guns. Licensed production of T-34 and T-54 started in the 1950s and a production base for independent production of armored vehicles was established. The anti-tank SPG named SDP 57 Gowika was designed to replace the obsolete Soviet SU-100 and ISU-122. The project was deemed a success, but the prototype was abandoned in favor of a more promising design.

SDP 58 Kilana

• Nation: Poland
• Tier: VIII
• Class: Tank Destroyer
• Research Cost: 137,500 XP
• Purchase Cost: 2,580,000 Silver

In 1957, Poland started designing advanced tanks and anti-tank SPGs. One such project was the SDP 58 Kilana with its gas-turbine engine. The armament and the power unit were designed using cutting-edge technologies provided by the U.S.S.R. To increase firepower, engineers used deep-rifled guns that were developed in the Soviet Union and given to Poland for testing. The project existed only in blueprints but became the foundation for later Polish tank destroyers.

SDP 60 Gonkiewicza

• Tier: IX
• Class: Tank Destroyer
• Research Cost: 242,500 XP
• Purchase Cost: 3,550,000 Silver

In 1960, a project for the SDP 60 Gonkiewicza heavy tank destroyer appeared in Poland. The well-armored vehicle was supposed to have good mobility. To achieve this, it was to be equipped with a small but powerful engine based on one of the early variants of the GTD-1 gas-turbine engine with a projected 1,000 h.p. Documentation on the engine was provided by the Soviet Union, which also shared materials on deep-rifled guns with its Polish colleagues, who developed their line of guns based on them. On the whole, the project was a success, but the vehicle was never built because of its high costs.

NC 70 Błyskawica

• Tier: X
• Class: Tank Destroyer
• Research Cost: 329,000 XP
• Purchase Cost: 6,100,000 Silver

The NC 70 Błyskawica tank destroyer was developed as an anti-armor vehicle and a means to destroy fortifications, as well as to suppress and destroy enemy artillery and infantry. The project was to use a new artillery system that ensured high initial shell velocity. The gun was to be hard-mounted in the cabin without using recoil absorbers, which decreased its complexity and cost. The power unit included two gas-turbine engines. The project existed only in blueprints.
