Design
- Maus: The Maus was a super heavy tank, weighing over 188 tons. It was armed with a powerful 128mm gun and two 75mm guns. It was also well armored, with up to 240 mm of armor on the front of the hull.
- T30: The T30 was a heavy tank, weighing over 72 tons. It was armed with a 155mm gun and a coaxial 37mm gun. It was also well armored, but lighter than the Maus, with 279 mm maximum frontal hull armor.
Mobility
- Maus: The Maus was notoriously slow and cumbersome, with a top speed of only 12mph (20km/h) and poor maneuverability. Its high weight put tremendous stress on its engine, transmission and suspension.
- T30: The T30 had the edge over the Maus in terms of mobility. It had a top speed of 24 mph (38 km/h) and better overall handling, thanks to its use of a more efficient Christie-type suspension system.
Reliability
- Maus: The Maus was plagued with mechanical issues, particularly with its transmission and powertrain, that hampered its combat effectiveness.
- T30: While also not immune to mechanical problems, the T30 was generally considered more reliable and practical compared to the Maus. It benefitted from a more well-tested and refined design that drew from previous M4 series tanks.
Production and Combat History
- Maus: Only a handful of Maus tanks were ever produced. They were initially intended to be used for defensive purposes, but they proved too slow and impractical for front-line combat. Only two prototypes were completed, and they never saw combat.
- T30: The T30 saw relatively limited production as well. Only six prototypes were built, and none of them were deployed to active duty during World War II. However, the T30 served as a testbed for various technologies like sloped armor and high-caliber guns that were later incorporated into other American tank designs.
Overall Comparison
- Maus: Impressive on paper, due to its heavy armor and powerful armament. However, its colossal weight, slow speed, and technical challenges rendered it less practical for combat.
- T30: While less heavily armored than the Maus, the T30's balanced design offered a mix of adequate protection, mobility and a potent gun. It served as a valuable prototyping platform, influencing future American heavy tank designs.
Ultimately, the T30 might be considered the more effective and practical tank, based on its better mobility and reliability. However, the Maus holds a place in history as one of the most iconic and extreme tank designs from World War II, representing the culmination of one possible approach to tank design.
