040 INTRODUCTION AND GENERAL DESCRIPTION

040-1 Background

The 11 meter Rigid Inflatable Boat (11m RIB) is a multi-purpose platform with several distinct missions. The terrorist attacks on the USS COLE (12 October 2000) and on multiple United States (U.S.) homeland targets (11 September 2001) added multiple missions to the traditional functions of a U.S. Navy boat. The current missions for the 11m RIB include:

Anti-terrorism/Force Protection (AT/FP)

Maritime Interdiction Operations (MIO)

Visit, Board, Search and Seizure (VBSS)

Safety Boat / Escort

Tow and Recovery Boat

Personnel and Cargo Transfer

The ability to be carried aboard and deployed from a variety of U.S. Navy ship classes is a critical operational requirement for U.S. Navy 11m RIBs. For the boats to be deployable from multiple ship classes, each boat must be compatible with a variety of existing shipboard handling and stowage systems including traditional davits and stowage chocks, and a variety of ship class specific launch, recovery, and handling systems.

A variant of the 11m RIB configured with a lifting frame and Cranston Eagle hook for interface to the Positive Control Derrick Head (PCDH) on a knuckle-boom crane and Caley davit docking head is used onboard the LPD-17 Class ships.

A variant of the 11m RIB referred to herein as the Enhanced VBSS (EVBSS) variant incorporates increased AT/FP, MIO, and VBSS capabilities. This variant uses the 11m RIB LPD-17 configuration as a baseline with increased engine horsepower to meet higher cruise and sprint speed requirements.

The 11m RIB platform entered service with the U.S. Navy in the early 2000s. Since then sequential Mk numbers designate major changes to the 11m RIB configuration. This Specification refers to the 4th version of this boat, the 11m RIB Mk4.

040-2 Variants

Three variants are described in this Specification: the base Open Center Console (OCC) variant, the LPD-17 variant, and the EVBSS variant. Unless the variant is identified, the Specification sections and Contract Drawings shall apply to all variants. Throughout the Specification and Contract Drawings, the variants shall be referred to as:

OCC

LPD-17

EVBSS

The below table summarizes the differences amongst the variants throughout this Specification.

Elsewhere, commonality between the variants shall be maintained in other respects as much as practicable.
