1 SCOPE

1.1 Scope

This specification describes the functional and performance requirements for the Enhanced

Combat Rubber Reconnaissance Craft (E-CRRC) which is the next generation inflatable raiding craft. Marine Corps reconnaissance personnel are in need of an improved inflatable craft used in conjunction with the fielded 55 hp Non-Gasoline Burning Outboard Engine (NBOE) in order to effectively execute amphibious reconnaissance missions. The E-CRRC will be used for insertion/recovery of personnel and the performance of related amphibious reconnaissance activities in a prospective landing area. It is essential to Marine Corps reconnaissance operations that a clandestine delivery means to enable personnel to cover extended distances across the ocean from the launch/recovery point to the objective area is provided. The newly designed craft must be capable of air drop/delivery in the execution of this primary mission of tactical insertion of small reconnaissance teams

1.2 System Description

The E-CRRC will have increased load carrying capacity as well as improved ride quality, speed, stability and seakeeping in heavy seas over the legacy CRRC. The improved ride quality will deliver Reconnaissance Marines to the objective with reduced fatigue and strain after long distance offshore transits.

1.3 Mission Profiles

The E-CRRC will be used to support Marine Corps reconnaissance missions to conduct amphibious raids. This involves swift incursions into hostile territory, conduct of the raid mission, and a planned withdrawal. Insertion into the mission area will be by ship, helicopter and fixed-wing aircraft. The system will operate across the spectrum of day and night, and in all climates and terrain in which the Marine Air Ground Task Force is employed.

1.4 Use of “Shall” and “Should”

The structure of this specification states requirements using two distinct language provisions: 1)

Binding provisions use the term “shall” to represent the threshold values and is the mandatory requirement, and 2) Non-mandatory provisions use the term “should” to represent the objective values and represents the desired operational performance.
