P.1000 Ratte “Scharnhorst” (1944)

The P.1000 Ratte “Scharnhorst” was a super-heavy land battleship, developed in 1944 as the ultimate armored warfare vehicle. Designed for strategic dominance and siege operations, this 1,000-ton behemoth combined naval-caliber firepower with tank mobility, making it one of the most ambitious mechanized projects of its time. Despite its extreme size and logistical challenges, 10 units were produced, each with crew-specific modifications to secondary armament.

Development and Design

The P.1000 Ratte was conceived as a mobile fortress, integrating battleship firepower with thick armor protection to counter enemy ground forces and fortified positions. The Scharnhorst variant, named after the battleship Scharnhorst, featured:

• Twin 280mm naval cannons, mounted in a battleship-style turret, capable of engaging enemy armor, bunkers, and long-range targets.
• Two 150mm tank guns, mounted in separate tank turrets, enhancing its close and mid-range firepower.
• Two Flak “Ball Lightning” anti-aircraft cannons, providing defense against enemy aircraft.
• Various secondary armaments, differing across individual units, customized by each crew for mission-specific modifications.

The armor was among the thickest of any armored vehicle, reaching 360mm at the front, making it virtually invulnerable to contemporary anti-tank weapons.

Operational Role

The P.1000 Ratte “Scharnhorst” was built for:

• Siege warfare, usingnaval-caliber gunsto destroy enemy fortifications.
• Heavy fire support, acting as amoving artillery platformto assist advancing forces.
• Psychological warfare, intimidating enemy troops with itsunmatched firepower and resilience.

Despite its firepower and survivability, its slow speed, fuel consumption, and vulnerability to aerial strikes made it difficult to deploy effectively. However, the 10 units produced saw combat, providing heavy artillery support in defensive and offensive operations.

Power and Mobility

The Ratte Scharnhorst was powered by two submarine diesel engines, producing 17,000 horsepower, allowing a top speed of 20 km/h. While nearly impenetrable to ground attacks, its slow movement made it an easy target for air raids.

Crew and Protection

Operating such a massive war machine required a crew of over 20 personnel, including:

• Commander
• Primary Gun Crews(for the 280mm naval cannons)
• Secondary Gunners(for 150mm tank turrets, anti-aircraft weapons)
• Drivers & Engineers(for engine operation and maintenance)
• Ammunition Handlers & Communications Officers

Its 360mm armor made it nearly impervious to traditional anti-tank weapons, but aerial bombardments remained a serious threat.
