PC-14 Tornado

This program acquires one additional ship and ancillary equipment for coastal patrol and interdiction and Naval Special Warfare Support. This is an NDI acquisition program. Upgrades to the fielded Patrol Coastal (PC) ship are planned under several of the PC programs.

Fleet Commanders in Chief (CINCLANTFLT and CINCPACFLT) are required to maintain the capability to conduct coastal patrol, surveillance and interdiction, and to maintain the capability to support Navy Special Warfare forces (SEALS) in their various areas of responsibility. The Patrol Coastal (PC) is intended to fulfill these coastal patrol, surveillence and interdiction roles. The PC-14 will also be employed to support Naval Special Warfare missions within the ships' inherent capabilities. The PC-14 will operate under warfighting doctrinal guidelines of NWP 39, Naval Coastal Warfare Doctrine; NWP 15, Naval Special Warfare; and NWP 13-1, Navy Riverine and Coastal Operations. PC is expected to operate primarily in low-intensity conflict (LIC) environments. Contingency scenarios will range from permissive Non-Combatant Evacuation Operations (NEO) to counterinsurgency and surveillence and interdiction of coastal sea lines of communication (SLOCs). The PC will also provide an affordable, compatible, and proven candidate for Foreign Military Sales (FMS) consideration.
