In modern warfare, self-propelled howitzers (SPHs) serve as vital artillery platforms, combining mobility, firepower, and rapid deployment. Two of the most well-known SPHs in service today are the K9 Vajra-T, operated by India, and the M109A7 Paladin, a mainstay of the United States Army.
Both systems are engineered for high-intensity, long-range indirect fire support, but they differ significantly in origin, design philosophy, battlefield roles, and technical specifications.
