Evidence & current status
Procurement, trials and service are distinguished; family figures are not transferable between variants.
Ranger and Mariner are large surface vessels used to develop and demonstrate naval autonomy. Leidos describes both as originating from fast supply vessel designs, with conversion and integration work by its Gibbs & Cox business. That origin differs from Sea Hunter and Seahawk, which were designed around autonomous operation from the outset.
The pair participated in the US Navy's Integrated Battle Problem 23.2 deployment across the Pacific alongside the two smaller vessels. This provides evidence of real deployed experimentation, including distant port visits and sustained support requirements. It does not turn aggregate fleet mileage into the range of an individual boat or establish that every subsystem operates without human supervision.
Leidos distinguishes the mechanical and electrical refinements incorporated into Mariner from the earlier Ranger. A shared programme label therefore does not mean identical hardware. The catalogue records the vessels as an established development and experimentation family, while later medium-USV production concepts need their own contracts and specification records. Publicly verified hull, payload and endurance figures were not recovered from the primary pages used in this pass and are left explicit rather than copied from secondary comparisons.
