Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Northrop M2-F3 | Statement: [Northrop M2-F2, successor, Northrop M2-F3]

Target entity: Northrop M2-F3
Context triple: [Northrop M2-F2, successor, Northrop M2-F3]

• A. Northrop M2-F2
  The Northrop M2-F2 was an experimental lifting-body research aircraft developed in the 1960s to study wingless reentry vehicle aerodynamics and landing characteristics for future spacecraft.
• B. Northrop M2-F1
  The Northrop M2-F1 was an early experimental lifting-body aircraft developed for NASA in the 1960s to investigate wingless reentry vehicle concepts and pave the way for future spaceplane designs.
• C. Northrop Alpha
  Northrop Alpha was an early all-metal, single-engine monoplane airliner and mailplane of the early 1930s that helped pioneer modern stressed-skin aircraft design.
• D. Northrop X-21
  The Northrop X-21 was an experimental U.S. jet aircraft of the 1960s designed to test laminar-flow control technology for improved aerodynamic efficiency.
• E. Douglas X-3 Stiletto
  The Douglas X-3 Stiletto was a slender, jet-powered experimental research aircraft of the early 1950s designed to investigate sustained supersonic flight and advanced aerodynamic concepts for future high-speed aircraft.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"
