How about split a "family" page about two completely unrelated aircraft families?
- I do not believe it is necessary. These family pages more serve as "Disambiguation" pages than to dedicate a vehicle family page, like say the M4 Sherman. The page does the job of linking vehicles with similar designations starting with SB2, and yet also makes a distinction that the SB2U and SB2C are different vehicles. --Inceptor57 (talk) 21:49, 28 March 2019 (UTC)
