1.0 INTRODUCTION
The U.S. Customs and Border Protection (CBP), Air and Marine Operations' (AMO) mission is to serve and protect the American people. The organization applies advanced aeronautical and maritime capability and employs its unique skill sets to support the overarching Department of Homeland Security (DHS) strategic goal. The Class 4 Inshore Patrol Vessel (IPV) specifically aligns with CBP missions and DHS missions by enhancing border security, bolstering enforcement capabilities, and expanding maritime awareness by patrolling, performing search and rescues, and performing law enforcement activities.
CBP seeks to replace the aging units within its fleet of Class 4 Inshore Patrol Vessels (IPV) with two patrol cases (PC):
• PC1: Patrol Boat-Small – Nimble vessels 25 foot or less that are designed for shallower, obstructed waterways, such as the Rio Grande.
• PC2: Patrol Boat-Medium – Stable vessels that are a minimum of 25 feet and a maximum of 29 feet that are designed for rougher, open waters, such as the Great Lakes.
The Class 4 Inshore Patrol is a vital platform used for conducting patrol, law enforcement, and search-and-rescue missions in diverse inshore operating environments. The Class 4 IPV will focus on deterrence, intelligence collection, and reconnaissance while also addressing interdictions, rescues, and law enforcement actions.
CBP seeks to enhance speed and endurance, improve weather resilience, increase seat capacity, upgrade mission systems, and standardize and expand current inventory. These characteristics translate into improved operational effectiveness and enable CBP to provide expeditious, effective, and reliable support.

010 CLASS 4 IPV OPERATIONS
010-1 General Mission Profile 010-1.1 The Class 4 IPV will operate in diverse environments in two principal states: patrol and response. The vessels will be selected and outfitted based on the mission requirements.
010-2 Concept of Operations 010-2.1 Mission Sets
010-2.1.1 Patrol 010-2.1.1.1 Patrol operations will focus on deterrence, intelligence collection, and reconnaissance. Class 4 IPVs will assist operators’ efforts to predict, detect, identify, classify, and track potential threats at the border. Class 4 IPVs will send and receive item-of-interest information to various command centers, other government agencies’ vessels, and Department of Homeland Security assets.
010-2.1.2 Response
010-2.1.2.1 Response operations will address interdictions, rescues, and law enforcement actions. Rescues will require the ability to come alongside other vessels and to safely retrieve personnel from the water. Law enforcement actions will require the Class 4 IPVs to come alongside other vessels safely without damaging either vessel.
010-2.2 Operating Description 010-2.2.1 Patrol 010-2.2.1.1 Operations are conducted in rivers, lakes, bays and the open inshore areas of the United States. Operations are conducted under a patrol mission set.
The crew will operate the vessel at cruise speeds of 25 to 35 knots to get to their patrolling Area of Responsibility (AOR), run at lower speeds while patrolling and return to base at cruise speed. The entire mission is expected to last for 6 to 8 hours prior to refueling. While transiting and during the mission, the vessel will encounter various environmental and wave conditions. While maneuvering in waves the Vessel Commander will fluctuate the throttle to mitigate impacts. These capabilities necessitate immediate throttle response; precision trim; minimally restricted visibility for the Vessel Commander; turning radius, acceleration, stopping distances, and similar controls at low and high speeds to maintain close formation between the Class 4 IPVs and an underway vessel including throttle response and precision steering at low speed. While on station, the crew will use the sensor systems and communication systems installed on the IPV to perform the patrol mission.
010-2.2.1.1.1 These operations normally require a standard crew consisting of one Vessel Commander and two crew members.

010-2.2.2 Response – Interdiction 010-2.2.2.1 During patrol of the AOR, the crew responds to cued information about illegal or suspicious vessel traffic. The vessel proceeds to locations at a high rate of speed no less than 40 knots (T) if wave conditions permit. The Target of Interest (TOI) is identified through radar or visually and engaged. This mission necessitates immediate throttle response; precision trim; minimally restricted visibility for Vessel Commander; highly responsive turning radius, acceleration, stopping distances, and similar controls at low and high speeds to maintain close formation between the Class 4 IPVs and an underway vessel; and throttle response and precision steering at low speed for personnel transfer to and from the TOI.
010-2.2.2.2 When approaching the TOI, the Vessel Commander observes that the TOI is aground and that personnel are in the water. The Class 4 IPV requires a shallow draft capability and precision throttle response and steering to allow approach to the TOI. The Class 4 IPVs require human recovery cutouts in the gunwale with a retractable ladder (T) to assist with recovery of personnel in the water.
010-2.2.2.3 These operations normally require a standard crew consisting of one Vessel Commander and two crew members.
