Enclosure (1) to COMDTINST 16114.20
c. INTERIM FORCE. The Interim Force represents a transitional state for the shore-
based response boat system between the Current Force and the Future Force. Essentially,
it "makes sense" of the myriad of boat types designations to position the Coast Guard for
a smooth transition to the Future Force. The Interim Force contains the six boat type
designations represented in the below tables. The next section of this enclosure will deal
with the specific actions to be taken during the transition from the Current Force to the
Interim Force (Phase 1) and from the Interim Force to the Future Force (Phase 2). In
anticipation of this Instruction, several Phase 1 changes have been made; however, other
changes (e.g., full force 47' MLB delivery and 44' MLB phase-out) will take several
years to complete.
