Aircraft
Upon departure we couldn't retract the landing gear. Upon reaching a safe altitude we ran the appropriate checklist; and performed a [precautionary] landing without incident.   Nothing could have prevented this event from occurring.
Captain reported landing gear would not retract on take off and elected to perform an air turn back and precautionary landing.
