;requirement : a formal name or a number for the requirement. Examples:
::* OR.229
::* Advanced Tactical Fighter Statement of Operational Need
; issuer : the issuer of the requirement or specification. This might be a government department, ministry, or agency rather than a service. Note that some programs might be jointly issued by more than one department or even more than one government. Example:

; initiated : the date that the program was initiated

::* program merged with [[TFX Program]]
; predecessors : predecessor programs that were abandoned in favour of this one, or merged into this one
; successors : programs in favour of which this program was abandoned, or into which this program was merged
