How this entity was disambiguated
This entity first appeared as the object of triple T10212031 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Atlas V 411
Atlas V 411 is a specific variant of the Atlas V expendable launch vehicle characterized by a single solid rocket booster and a four-meter payload fairing, used to place satellites and spacecraft into orbit.
-
B.
Atlas V 531
Atlas V 531 is a medium- to heavy-lift variant of the Atlas V launch vehicle that uses a five-meter payload fairing, three solid rocket boosters, and a single-engine Centaur upper stage to deliver satellites and spacecraft to orbit.
-
C.
Atlas V 501
Atlas V 501 is a specific configuration of the Atlas V expendable launch vehicle optimized for launching medium-sized payloads, particularly satellites, into orbit.
-
D.
Atlas V 541
Atlas V 541 is a heavy-lift configuration of the Atlas V expendable launch system used by NASA to send large interplanetary spacecraft, such as the Curiosity Mars rover, into space.
-
E.
Atlas V 521
Atlas V 521 is a medium- to heavy-lift variant of the Atlas V launch vehicle, distinguished by its five-meter payload fairing, two solid rocket boosters, and single-engine Centaur upper stage, used primarily for launching large satellites to high orbits.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Atlas V 401 Description of subject: Atlas V 401 is a configuration of the Atlas V expendable launch vehicle known for reliably launching interplanetary missions and Earth-orbiting payloads.
