War reserve materiel (WRM) all-up-round missiles with guidance and control units removed are called?

The term used to describe war reserve materiel (WRM) all-up-round missiles with guidance and control units removed is commonly referred to as donor missiles. This designation is appropriate because these missiles are intended to provide components or systems to other missiles, which may require replacement parts or upgrades. By removing the guidance and control units, the missile can serve as a source of valuable functionality that can be utilized in operational systems, ensuring higher readiness and maintenance efficiency for active missile stockpiles.

The other options, while they might sound plausible, do not accurately describe the specific function of these missiles. Parts missiles would suggest that the entire missile is intended solely for parts, which isn't the case here. Dummy missiles typically refer to non-functional models used for training or testing, while support missiles might imply a role in logistical or operational support, which doesn't convey the essential aspect of being a source for components. Therefore, donor missiles is the most accurate terminology reflecting the role and condition of the described WRM items.
