Naval Sea Systems Command is comprised of command staff, headquarters directorates, affiliated program executive offices (PEOs) and numerous field activities. NAVSEA is accountable to the Chief of Naval Operations to deliver, modernize and maintain a 313-ship Navy that meets our national security requirements. NAVSEA has the further responsibility of establishing and enforcing technical authority in combat system design and operation. NAVSEA's technical standards ensure systems are engineered effectively, and that they operate safely and reliably.
NAVSEA is the "technical authority" for the following electromagnetic spectrum-related issues that affect ships and submarines: electromagnetic interference (EMI) control; electromagnetic compatibility (EMC); electromagnetic pulse (EMP); and radiation hazards (RADHAZ). As a technical warrant holder, NAVSEA's Force E3/Spectrum Office controls EMI, the spectrum and EMP impact on the effectiveness of warfare systems, to maintain warfighting readiness for all ships, submarines and systems.
The electromagnetic environment (EME), in which naval systems must operate, is created by a multitude of sources. Primary contributors are ships, forces, other friendly transmissions, enemy transmissions, spurious emissions from equipment, the ship's metallic hull, natural and environmental noise, and possibly EMP resulting from a nuclear burst. The dominant contributor(s) to the EME depend on the platform's (or system's) location and operating circumstances. Many elements of the EME are vital to system performance; others are potential sources of EMI. Electromagnetic signals vital to one system's performance may prove fatal to another system's performance. An increased awareness of the EME will enhance identification and reduction of platform/system EMI.
Defense Department policy requires all electrical and electronic systems, subsystems and equipment, including ordnance containing electrically initiated devices, to be mutually compatible in their intended EME without causing or suffering unacceptable mission degradation due to electromagnetic environmental effects (E3).
Accordingly, appropriate E3 requirements must be imposed to ensure a desired level of compatibility with collocated equipment (intra-system) within the applicable external EME that may include intersystem, radio frequency, lightning, EMP and precipitation static. E3 requirements must also address safety of personnel, ordnance and fuel.
In addition, national, international and DoD policies and procedures for the management and use of the electromagnetic spectrum direct program managers developing spectrum-dependent systems or equipment to consider spectrum supportability requirements and E3 control early in the development process, and throughout the acquisition life cycle.
NAVSEA's Force E3/Spectrum Office's goal is to partner with each system, ship or submarine program to provide the best products to the warfighter. This is accomplished by getting plugged-in at the earliest stages of program development. NAVSEA subject matter experts help guide individual programs through the E3/spectrum certification (SC) process, requirements identification and controls implementation, and through the Technical Warrant Pyramid (Figure 1).
NAVSEA Headquarters leads the tri-SYSCOM organization consisting of Space and Naval Warfare Systems Command (SPAWAR), NAVSEA and Naval Air Systems Command (NAVAIR) for EMI control, EMP and spectrum certification matters.
Figure 1 shows the top-down organization of the Force Level EMC Program. At the headquarters level, front line systems engineers interface with the various PEOs (PEO Ships, PEO Carriers, etc.). At the field activity level, NAVSEA designates engineering agents (EAs) for specific functional areas. These EAs form teams of subject matter experts to assist in the investigation and resolution of EMI problems ashore and afloat. These activities champion and execute E3/spectrum management (SM) in the design, development, procurement and integration of equipment and platforms, as well as naval shore sites.
The Technical Warrant Pyramid illustrates the depth of knowledge and expertise that exists within the Force Level EMC Program. This team maximizes operational performance and safety with respect to E3 and spectrum management in ships and submarines, their combat systems and shore installations.
The key to enable future naval capabilities is well-engineered warfare systems. This is accomplished through a disciplined up-front systems engineering effort, which includes the review of acquisition documents (initial capability documents, capability development documents, capability production documents, or capstone requirements documents).
To ensure EMC for new systems introduced into the fleet, NAVSEA reviews ship change documents and ensures that systems attain spectrum certification. NAVSEA ensures the performance and readiness of current naval systems and that platforms are ready to fight by executing shipboard EMC and RADHAZ certification, the Submarine Pre-Deployment EMC Survey, and providing direct fleet and program manager support. The NAVSEA team exercises technical authority by holding formal technical warrant holder reviews, thereby enforcing electromagnetic environmental effects/spectrum certification acquisition policies and providing E3/SC technical subject matter expert guidance.
In September 2009, the Chief of Naval Operations issued Guidance for 2010 for Executing the Maritime Strategy. It reviews the Navy’s major 2009 accomplishments and reaffirms the vision, mission, guiding principles and focus areas articulated in last year’s guidance.
The Navy’s focus areas remain:
• Build the future force.
• Maintain our warfighting readiness.
• Develop and support our Sailors and Navy civilians.
The CNO Guidance 2010 places emphasis on the following five objectives:
• Continue to be the dominant, ready naval force across all maritime missions.
• Build a Navy with appropriate force structure and strategic laydown.
• Achieve decision superiority.
• Align the requirements, resources and acquisition processes.
• Evolve and establish international relationships.
The CNO Guidance is a basis for NAVSEA's Force E3/Spectrum Office’s goals to ensure we build the future force through an up-front engineering process and maintain our warfighting readiness through ship maintenance and developing our Sailors and Navy civilians.
Mr. D. Mark Johnson is the OPNAV program spectrum supportability, elec-tromagnetic environmental effects and electromagnetic pulse coordinator. Mr. J. Don Pierce, is the director of the NAVSEA Force Level E3/Spectrum Office.
