N88-NTSP-A-50-XXXX/D

NOVEMBER 1999

EXECUTIVE SUMMARY

The AN/SPN-35C Aircraft Control Approach Central Radar Set is an upgrade to the current AN/SPN-35B. The AN/SPN-35B is deployed on the Landing Helicopter (LH) type ships to provide mode III localizer and glide slope guidance to Navy and Marine Corps aircraft. The AN/SPN-35B radar set is used in conjunction with a Vertical/Short Take-off and Landing, Optical Landing System and the AN/SPN-41A Instrument Control Landing System for precision landing operations. The AN/SPN-35C upgrade requirements are to simplify maintenance and radar operations and improve reliability, maintainability, and system performance. These requirements will be met by replacing the antenna drive reducer motors, antenna actuators, antenna control circuits, transmitter, receiver, and display consoles. Additional system performance improvements will be made by adding Moving Target Detection (MTD), Track While Scan (TWS) capabilities, and Built-In Test (BIT) capabilities. The MTD capability will improve the performance of the AN/SPN-35C when operating in rain at rates up to 16 millimeters per hour and at ranges to 10 nautical miles. The TWS will provide an additional capability for recovering AV-8Bs during the transition from forward flight to hover. The AN/SPN-35 program is in Phase III (Production, Deployment, and Operational Support) of the Weapon System Acquisition Process. Initial Operating Capability of the AN/SPN-35C is planned for Fiscal Year 2001.

The AN/SPN-35C will not impact current manning onboard LH type ships. Personnel currently assigned to ships that operate and maintain the AN/SPN-35B will operate and maintain the AN/SPN-35C. The AN/SPN-35C will be operated by Air Traffic Controllers (AC) with Naval Enlisted Classification (NEC) 6903 assigned to the Amphibious Air Traffic Control Center. The AN/SPN-35C will not require any changes to the operational concept.

The maintenance concept for the AN/SPN-35C is based on two levels of maintenance, organizational and depot. No intermediate level maintenance is required. The upgrade to the AN/SPN-35C configuration will not cause any change to the current maintenance concept. The Electronics Technician (ET) rating with NEC 9602 will maintain the AN/SPN-35C.

Initial and follow-on training will be required for AN/SPN-35C operators and maintainers. The In-Service Engineering Agent (ISEA), Naval Air Warfare Center Aircraft Division (NAVAIRWARCENACDIV) St. Inigoes, Maryland, will provide initial training, and Naval Air Technical Training Center (NATTC) Pensacola, Florida, will provide follow-on training. NATTC Pensacola will develop the curricula for the operator and maintainer courses with technical assistance provided by ISEA, NAVAIRWARCENACDIV St. Inigoes.

H. CONCEPTS

1. Operational Concept. The AN/SPN-35C will be operated by Air Traffic Controllers (AC) with Naval Enlisted Classification (NEC) 6903 assigned to the Amphibious Air Traffic Control Center (AATCC), during amphibious air operations (launches and recoveries) as required. The AN/SPN-35C will not require any changes to the current operational concept.

2. Maintenance Concept. The maintenance concept for the AN/SPN-35C is based on two levels of maintenance, organizational and depot. No intermediate level of maintenance is required. The upgrade to the AN/SPN-35C configuration will not cause any change to the current maintenance concept.

a. Organizational. Electronics Technician (ET) personnel with NEC 9602 will maintain the AN/SPN-35C. Organizational level maintenance consists of both Preventive Maintenance (PM) and Corrective Maintenance (CM) actions.

(1) Preventive Maintenance. Organizational level PM in support of the AN/SPN-35C will be accomplished per Maintenance Requirement Cards (MRCs) and maintenance manuals prepared for the system. PM consists of inspection, cleaning, lubricating, pressurization checks, calibration, and operational checks.

(2) Corrective Maintenance. Organizational level CM in support of the AN/SPN-35C consists of fault isolation to Weapon Replaceable Assemblies (WRA) and Shop Replaceable Assemblies (SRA) using BIT, Maintenance Assist Modules (MAMs), and General Purpose Electronic Test Equipment (GPETE). CM also includes removal and replacement of faulty WRAs and SRAs, and operational test to verify repairs.

b. Intermediate. NA

c. Depot. Depot level maintenance consists of repairs to WRAs and SRAs beyond the capability of organizational maintenance. The depot site for the AN/SPN-35C will be determined at a future date.

d. Interim Maintenance. In-Service Engineering Agents (ISEA) provide technical assistance on an as-required basis, from NAVAIRWARCENACDIV (Code 4.5.8.1.2), St. Inigoes. The Material Support Date for the AN/SPN-35C is scheduled for December 2002.

e. Life-Cycle Maintenance Plan. NA

3. Manning Concept. The AN/SPN-35C will not impact current manning onboard LH type ships. Personnel currently assigned to the ships that operate and maintain the AN/SPN-35B will operate and maintain the AN/SPN-35C. Refer to Part II of this NTSP for specific activity manpower requirements.

4. Training Concept. Initial and follow-on training will be required for AN/SPN-35C operators and maintainers. ISEA, NAVAIRWARCENACDIV St. Inigoes, will provide initial training and Naval Air Technical Training Center (NATTC) Pensacola, Florida, will provide follow-on training. NATTC Pensacola will develop the curricula for the operator and maintainer courses with technical assistance provided by ISEA, NAVAIRWARCENACDIV St. Inigoes. The AN/SPN-35C will be incorporated into existing follow-on courses.

a. Initial Training. ISEA, NAVAIRWARCENACDIV St. Inigoes, will provide initial instructor training at NATTC Pensacola and provide initial training onboard the ships (as required) concurrent with AN/SPN-35C installation. This requirement for shipboard training will exist until NATTC Pensacola begins teaching the follow-on courses. The initial training onboard ship is expected to begin during second quarter FY01 and NATTC instructor training is scheduled for third quarter FY01.
