Section 1: Scope 74 This Circular of Requirements (CoR) defines the requirements for the Light Amphibious Warship (LAW). LAW 75 will be a new ship designed to support the employment of the Marine Littoral Regiment (MLR) by providing direct 76 conveyance to beaches in order to on-load and off-load expeditionary forces, equipment and supplies. The vessel 77 shall provide mobility of forces from the point of embarkation (beach, marina, harbor, or port) through the littorals, 78 across Open Ocean, and to a point of debarkation (beach, marina, harbor, or port) that affords maritime tactical 79 advantage. 80

Section 2: Applicable Documents 81

Compliance with referenced documents is mandatory even where the referenced document may use terms similar to 82 “recommendation”, “guideline” or “guidance” in their title or text. 83

Order of precedence - First tier references take precedence over sub-tier references in the event of a conflict. 84 Nothing in this document shall supersede applicable laws and regulations unless a specific exemption has been 85 obtained. In case of conflict between ABS Rules or USCG Regulations, and specific requirements of this CoR, the 86 ABS Rules and USCG Regulations take precedence, unless the specific CoR requirements exceed the ABS Rules 87 and USCG Regulations, in which case the specific CoR requirements takes precedence. 88

Silence of one document with respect to details or requirements in another document shall not be considered an 89 inconsistency. 90

Order of Order of Precedence of requirements within the Expanded Ship Work Breakdown Structure Sections of the 91 LAW CoR is as follows: 92

Requirements within a SWBS Section applicable to the entire ship (for example, SWBS Section 070 - 93 General Requirements for Design and Construction) state the broadest requirements and apply to 94 systems and equipment, unless otherwise specified in the more detailed SWBS Sections, in which case 95 the detailed SWBS Section requirements apply. 96

Specific requirements within a lead, 1-digit SWBS Section (for example, a SWBS Section which 97 includes the general or common requirements for a number of similar systems, such as SWBS Section 98 500 - Auxiliary Systems, General) are the next broadest category of requirements, and shall apply to 99 systems and equipment in its grouping as well as other ship systems where applicable, unless otherwise 100 specified in detail system SWBS Sections. 101

Specific requirements within a 2-digit SWBS Section (for example, a SWBS Section which includes 102 the details of a particular system such as SWBS 530, Fresh Water Systems) are the next broadest 103 category of requirements and shall apply to systems and equipment in its grouping, unless otherwise 104 specified in detail system SWBS Sections. 105

Specific requirements within a detailed, 3-digit SWBS Section (for example, a SWBS Section which 106 includes the details of a particular system such as SWBS 533, Potable Water Systems) are the most 107 detailed requirements. Requirements in these detailed system SWBS Sections apply for the system 108 covered in the detailed SWBS Section. 109

The omission in one SWBS Section of details covered in another SWBS Section shall not be 110 considered a conflict. 111

In the event that two or more requirements of equal precedence are found to apparently conflict, the 112 Contractor shall formally identify the conflict to the Government for clarification, or correction of the 113 specifications, as appropriate. 114

Effective issue - Where first tier references, such as industry standards, are referred to, the issue or 115 revision/amendment in effect at Detail Design and Construction Contract Award shall apply. The current version is 116 acceptable only if approved by the government, and is used in its entirety. 117

First Tier and Sub-tier Reference - Any referenced document that is directly cited for use or application by an 118 identifying number or name in this CoR is a first tier reference for each particular use or application for which it is 119 so cited. Any document that is cited in a first tier reference, or in a document referenced therein, is a sub tier 120 reference. A document that is a sub-tier reference in one application may also be a first tier reference in another 121 application when it is cited directly. 122

Type Drawing – A NAVSEA drawing identified as "Type Drawing" which delineates or illustrates design features 123 of systems or components. No departure from any feature identified as "mandatory" shall be made without specific 124 approval. The illustrative features are subject to detail design development to assure full compliance with these 125 specifications. 126

U.S. Navy Design Data Sheets, Design Practice and Criteria (DDS/DPC) - Documents that contain information 127 for guidance in the design and construction of ship features or systems. Design Data Sheets illustrate typical design 128 and calculation methods and procedures which are acceptable to the Government 129

Standard Drawing – A NAVSEA drawing identified as a "Standard Drawing" which delineates arrangements or 130 details of systems, equipment or components. No departure from a standard drawing is permitted without specific 131 written approval of the Contracting Officer. 132
