Which aircraft is known as the "angel of mercy"?

The designation of the "angel of mercy" is historically associated with the OH-13 helicopter, primarily due to its role in medical evacuations and its use during the Vietnam War. The OH-13, also known for its iconic bubble canopy and light frame, was often utilized for medevac missions, directly contributing to the safe retrieval of wounded soldiers from the battlefield.

The reputation of the OH-13 as the "angel of mercy" stems from its effectiveness in saving lives, particularly in rapidly dangerous and evolving conditions. This helicopter's ability to navigate through challenging terrain while providing immediate medical assistance made it a critical asset in air ambulances, earning the affectionate nickname for its life-saving role.

In contrast, while the UH-60 Black Hawk and CH-47 Chinook perform essential transport and support functions, they are not typically referred to by this moniker; the AH-64 Apache is primarily an attack helicopter, focused on combat rather than medical evacuation. Thus, the OH-13's association with mercy and its vital role in lifesaving operations in combat settings solidifies its status as the "angel of mercy."
