USS Daniel Soule (NCC-1655) was a Constitution-class heavy cruiser — of the Enterprise-subclass — on active duty in Starfleet during at least the late 23rd century. Daniel Soule — whose first commanding officer was Fleet Captain Dana Marshall and whose first executive officer was Commodore Keith Marshall — was deployed to the Starfleet Fifth Fleet for most of its operational lifetime.
