We were taught the USCG was the oldest, continuous seagoing service because the US Navy's disbanding after the rdvolution.
The Revenue Cutter Service was founded in 1790, and is one of the major roots of the USCG past. 4 years earlier than the US Navy's second esrablishment.
But everyone in the USCG really likes the Navy (to a point
)...because we were taught the USCG is the hard nucleus that the Navy forms on in time of war....
