Development background and role
mediumH155 / EC155 Dauphin 2 is best understood through its original airframe lineage and the government or military support roles that made it relevant beyond civil aviation.
H155 / EC155 Dauphin 2 is not a combat aircraft in the narrow sense. It is a medium twin-engine helicopter developed from the Dauphin family for civil, parapublic, and government transport roles. Its military relevance comes from how armed forces and government agencies adapt proven aviation platforms for transport, command movement, research, training, liaison, or specialist support tasks.
This distinction matters for database quality. Several of these rows carry legacy category labels that can be too broad or wrong. A business jet should not be treated as a helicopter, and a light utility helicopter should not be described like a heavy transport. The useful content is the platform's actual mission fit.
For readers, H155 / EC155 Dauphin 2 should be evaluated as an enabling aircraft. It helps move people, sensors, crews, or mission equipment in ways that support military operations even when it is not firing weapons.
