EXECUTIVE SUMMARY

This Draft Navy Training System Plan (NTSP) identifies the manpower, personnel, and training requirements associated with the AIMS Mark XII Identification Friend or Foe (IFF) system, hereafter referred to as MK XII. The MK XII is a radar beacon system used by surface ships, submarines, aircraft, and ground forces to identify one another and to distinguish themselves from hostile and neutral forces. The MK XII system performs several different functions in support of various missions, such as anti-air warfare, aerial bombardment, naval bombardment, and naval attack. The MK XII also provides identification and altitude information for aircraft, a military and Federal Aviation Administration requirement for peacetime operational use of national airspace, and a Department of Defense requirement to maintain secure military identification.

Although mature, the MK XII continues to evolve as technology advances the capabilities of existing MK XII equipment and improved interface systems develop. A new digital interrogator, AN/UPX-XX, is currently under development to replace the existing AN/UPX-25(V) and AN/UPX-27 analog interrogators used in early MK XII systems. The new digital interrogator is in Phase III (Production, Deployment, and Operational Support) of the Weapon System Acquisition Process. Initial Operational Capability for the AN/UPX-XX is scheduled for third quarter FY00.

The MK XII is operated by officers and Operations Specialists assigned to the ships Combat Information Center (CIC). There are no operator or watchstation billets specifically dedicated to the MK XII. Electronics Technicians with Navy Enlisted Classification 1572 perform MK XII organizational and intermediate level maintenance. The Space and Naval Warfare System Command Center, San Diego, California, performs depot level maintenance.

No operator courses are taught exclusively for the MK XII system. System operation is taught as a by-product of the primary mission of CIC officer and Operations Specialist training courses. MK XII organizational and intermediate level maintenance training is established at Fleet Training Center, Norfolk, Virginia. The AIMS MK XII IFF Systems Maintenance course, A-102-0062, underwent a Surface Warfare Technical Readiness Review in 1997. As a result, course content was streamlined and the length reduced from 22 to 16 weeks.

Since the MK XII is a mature system, all manpower requirements are established. No change to existing manpower is required by incorporation of the new AN/UPX-XX digital interrogator.

D. SYSTEM DESCRIPTION

1. Operational Uses. The MK XII System is a radar beacon system used by surface ships, submarines, aircraft, and ground forces to identify one another and to distinguish themselves from hostile and neutral forces. The MK XII System performs several different functions in support of various missions, such as anti-air warfare, aerial bombardment, naval bombardment, and naval attack. In addition, the MK XII provides identification and altitude information for aircraft.

2. Foreign Military Sales. Other countries currently procure various types and quantities of MK XII components. Additional information concerning MK XII Foreign Military Sales (FMS) is available through Naval Air Systems Command (NAVAIRSYSCOM), PMA213.

E. DEVELOPMENTAL TEST AND OPERATIONAL TEST. The Chief of Naval Material approved the MK XII for Fleet use in March 1971. The approval was based on the successful Technical Evaluations (TECHEVAL) and Operational Evaluations (OPEVAL) of individual system components. As updated and modified components were incorporated into the MK XII System, acceptance tests were performed as necessary. No additional TECHEVALs or OPEVALs were conducted on these components since they did not meet requirement thresholds.

Developmental Test and Evaluation and (DT&E) and Operational Test and Evaluation (OT&E) will be performed on the new AN/UPX-XX digital interrogator. DT&E is currently scheduled to begin in third quarter FY99, with OT&E scheduled to begin in first quarter FY00. As it becomes available, information concerning these tests will be added to future updates to this NTSP.

F. AIRCRAFT AND/OR EQUIPMENT/SYSTEM/SUBSYSTEM REPLACED. The MK XII replaced the MK X Selective Identification Feature (SIF) System. The MK XII is functionally compatible with the MK X SIF.

G. DESCRIPTION OF NEW DEVELOPMENT

1. Functional Description. The MK XII System operates on the challenge-response principle. The system has five interrogation modes that can be used alone or in combination, allowing for several operational functions. The system also serves as a secondary radar to assist in tracking friendly forces, especially when radar return is obscured by clutter. Secondary radar is also required for air traffic control use when the target is out of range of the primary radar. Specific modes are:

    • Mode 1 - used as directed by field commands with 32 response codes available.
    • Mode 2 - used for platform identification by specific airframe or ship with 4,096 response codes available.
    • Mode 3/A - used for air traffic control identification inside the Continental United States (CONUS) and is assigned by the operational command outside of CONUS, (4,096 response codes are available).
    • Mode 4 - provides secure identification of friendly platforms and is classified.
    • Mode C - provides barometric pressure altitude of aircraft in 100 foot increments, from minus 1000 feet to +126,700 feet above sea level.

The MK XII is composed of an interrogator (challenge) subsystem and a transponder (reply) subsystem. The interrogator subsystem permits a radar operator to interrogate other platforms and to interpret this data as specific identification of friendly radar targets. The interrogator subsystem may be either a "black" IFF or a "slaved" IFF. Black IFF is a "stand alone" interrogator subsystem not associated with any radar system; only IFF returns can be displayed. With slaved IFF, the interrogator is synchronized with a radar set. The operator can display IFF only, radar only, or both.

The transponder subsystem accepts a challenge from other platforms and provides the necessary coded replies as identification. The transponder subsystems used aboard ships are aircraft transponder sets adapted for shipboard use. Most large surface ships are equipped with one transponder and one or more interrogators. Smaller surface ships are transponder-only equipped. The MK XII was designed to prevent the transponder from responding to self-interrogation. Components of each subsystem are described below.

a. Interrogator Subsystem. The Interrogator Subsystem "questions" weapons system platforms by transmitting an encoded signal to evoke a response for identification. The interrogator subsystem is comprised of:

(1) AN/UPX-25(V) Interrogator Set. The AN/UPX-25(V) Interrogator Set is an electrical equipment cabinet that integrates the individual components of an interrogator system into a single enclosure.

(2) Interrogator. The Interrogator consists of a transmitter and receiver capable of interrogating MK X SIF and MK XII IFF transponders by receiving Radio Frequency (RF) replies. The interrogator processes these replies into proper video signals that are then applied to decoders and indicators. The interrogator sets include the AN/UPX-27. The new AN/UPX-XX digital interrogator will contain both AN/UPX-25(V) and AN/UPX-27 functionality and will replace all AN/UPX-27 interrogator systems.

The AN/UPX-29(V) Central IFF (CIFF) System is an enhanced IFF system that provides all of the AIMS features, but performs these functions as a stand-alone system. This system will be employed aboard AEGIS and LHD-1 class ships. The AN/UPX-29(V) is not included in this NTSP. Refer to the AN/UPX-29(V) Interrogator System Navy Training Plan (NTP), E-30-7815B/D dated 25 April 1996 for further information.

The AN/UPX-30 CIFF is a new configuration and is not included in this NTSP; refer to the AN/UPX-30 CIFF NTP, E-30-8407B/A dated 23 August 1995.

(3) Directional Antenna. The Directional Antenna is capable of generating sum and difference patterns for Interrogation Side Lobe Suppression (ISLS) capability. The AS-2188/U, AS-2189/U, or AS-2787/UPX Directional Antenna is mounted "piggy-back" to the search radar antenna or is slaved to the antenna when mounted on a separate pedestal.

(4) AS-177( )/UPX Omnidirectional Antenna. The AS-177/UPX, AS-177A/UPX, and AS-177B/UPX Omnidirectional Antennas provide side lobe suppression when used with the interrogator, via the AN/UPA-61 RF Switching Group.

(5) AN/UPA-57 Antenna Pedestal Group. The AN/UPA-57 Antenna Pedestal Group is required to support and position an IFF antenna when not attached to the radar antenna. This is accomplished by either synchronism to a remote command (slave) input, synchronism to manual command input, or independently at an adjustable continuous rate. The AN/UPA-57 consists of a pedestal assembly, control unit, manual antenna positioning control, and mast switch.

(6) AN/UPA-61 Radio Frequency Switching Group. The AN/UPA-61 RF Switching Group provides automatic ISLS RF switching capability that enables a ship's antenna to function alternately as a directional and side lobe suppression antenna in an IFF system. It can also alternate between a directional antenna and an omnidirectional antenna. The AN/UPA-61 consists of an electronic switch assembly and control monitor assembly.

(7) Pulse Generators. The SG-841/UPX Pulse Generator samples the trigger of the associated radar and ensures the IFF video appears at the correct time. The SG-1066/UPX Pulse Generator is a video retimer that stores, processes, and retimes Mode 4 video signals.

(8) SN-501/UPX Video Synchronizer. The SN-501/UPX Video Synchronizer permits optimum operation of the IFF regardless of the many variations in radar timing that may occur. It is capable of interfacing two separate radar systems with one IFF interrogating subsystem when using a common radar antenna system.

(9) MX-8758( )/UPX Interference Blankers. The MX-8758/UPX and MX-8758A/UPX Interference Blankers are single channel defruiters that eliminate random non-synchronous signals. These signals appear as unsynchronized replies, or momentary clutter on the radar display, and are referred to as "fruit."

(10) AN/UPA-59( ) Decoder Groups. The AN/UPA-59A(V), and AN/UPA-59B are automatic decoding systems that operate in conjunction with interrogators. Each decoder group processes pulse-coded replies received by the interrogator system and provides video outputs to the Planned Position Indicator (PPI), or Naval Tactical Data System (NTDS) display console and on direct readouts. There are several configurations of the AN/UPA-59( ). These decoder groups basically consist of an alarm monitor, intratarget data indicator, and video decoder.

(11) C-8430/UPX Master Identification Friend or Foe Control Monitor. Each interrogator sub-system requires one C-8430/UPX Master IFF Control Monitor to provide controls, indicators, and alarms to the operations supervisor. The C-8430/UPX is located in the Combat Information Center (CIC).

(12) KIR-1C/TSEC Crypto Computer. The KIR-1C/TSEC Crypto Computers use the MT-4667/U computer base to provide Mode 4 crypto coding for the AN/UPX-27 interrogators and crypto decoding of Mode 4 transponder replies.

(13) KIK-18( )/TSEC, KYK-13, KOI-18-01 Crypto Code Keys. The KIK-18/TSEC and KIK-18A/TSEC Crypto Code Key sets the individual cryptographic codes for the KIR-1( )/ TSEC and KIT-1( )/TSEC (see transponder system below). For the KIR-1C and KIT-1C, the KYK-13 and KOI-18-01 are paper code keys that set the codes.

b. Transponder Subsystem. When interrogated, the Transponder Subsystem automatically replies by transmitting an encoded signal. The transponder subsystems use aircraft transponder sets adapted for shipboard use. The following components are included in the transponder subsystem.

(1) AN/UPX-28(V) Transponder Set. The AN/UPX-28(V) Transponder Set is an electrical equipment cabinet that integrates the transponder and its ancillary equipment into a single enclosure.

(2) Transponder. The RT859A/APX-72 Transponder is used aboard ships as a receiver-transmitter which, when properly challenged, automatically processes and transmits coded replies. The AN/APX-72 is capable of responding to a single mode, a combination of modes, or all five modes. The AN/APX-100 Transponder, which will replace the AN/APX-72, is an enhanced transponder with all the capabilities of its predecessor.

(3) AS-177( )/UPX Omnidirectional Antenna. The AS-177/UPX, AS-177A/UPX, and AS-177B/UPX Omnidirectional Antennas receives IFF interrogations for processing by the transponder and then radiates subsequent replies. The omnidirectional antenna also operates in conjunction with the AN/UPM-155 Test Set for systems tests.

(4) PP-6099( )/APX-72 Power Supply Converter. The PP-6099( )/APX-72 Power Supply Converter is required to convert 115 VAC to 28 VDC for the shipboard operation of the AN/APX-72 and AN/APX-100 Transponder Sets. Several versions are available for the specific type of transponder.

(5) C-6280( )/APX-72 Transponder Control Unit. The C-6280( )/APX-72 Transponder Control Unit is required to provide controls, indicators, and alarms for the transponder system. The controls on the front panel are used to determine the status of the transponder, the reply codes for Modes 1 and 3, and which interrogations require a reply.

(6) CY-6816/APX-72 Control Enclosure. The CY-6816/APX-72 Control Enclosure adapts the C-6280( )/APX-72 Transponder Control Unit to shipboard use.

(7) TS-1843( )/APX Transponder Test Set. The TS-1843( )/APX Transponder Test Set is an in-line test set that evaluates performance characteristics of the transponder system and provides indications on a "Go" or "No Go" basis.

(8) KIT-1C/TSEC Crypto Computer. The KIT-1C/TSEC Crypto Computer decodes interrogations and produces the appropriate coded replies.

(9) KIK-18( )/TSEC, KYK-13, and KOI-18-01 Crypto Code Keys. As mentioned above, under the Interrogator System, one Crypto Code Key is supplied per AIMS installation to set individual crypto codes. Some AIMS installations are transponder-only, in which case the key will be supplied for the KIT-1( )/TSEC Crypto Computer only.

(10) TD-937( )/SPX Electronic Gate. The TD-937( )/SPX Electronic (or Suppression) Gate suppresses the transponder when a ship's own interrogators, or other local source, is transmitting challenges. This prevents the transponder from replying to any interrogators or radar transmissions from its own emissions. Transponder-only ships do not normally include the TD-937( )/SPX..

3. New Development Introduction. The MK XII was retrofitted into ships that previously employed the MK X. The MK XII was installed during the production of new acquisitions subsequent to the MK X. The new AN/UPX-XX Digital Interrogator will replace the existing AN/UPX-27 on a one-for-one basis by retrofitting each system.

4. Significant Interfaces. In addition to the various shipboard radars, whose trigger format and video processing techniques affect radar-IFF relationships, the MK XII electrically interfaces with other systems and equipment that have an impact on overall radar-IFF system performance. These interfaces include video amplifiers, radar and data distribution switchboards, electronic countermeasure blankers, radar azimuth converters, and PPI displays or NTDS consoles. On NTDS ships, the IFF systems also interconnect, through data distribution switchboards, with a video signal simulator used as training equipment and a beacon video processor that interfaces IFF data with the NTDS.

For air traffic control operations, the IFF interfaces with the AN/TPX-42A (V)8 Carrier Air Traffic Control Center (CATCC) Direct Altitude Identification Readout (DAIR) Interrogator Set. Other system interfaces include ship's gyro, Radar Environmental Simulation System, and Target Acquisition System radar.

Functional interfaces of the Navy's AIMS include the Air Force's and Army's AIMS and the Federal Aviation Administration's Air Traffic Control Radar Beacon System (ATCRBS). The MK XII also interfaces with its predecessor, the MK X SIF.

5. New Features, Configurations, or Material. Not Applicable (NA).

H. CONCEPTS

1. Operational Concept. Operator duties for the MK XII consist of energizing and de-energizing the equipment, selecting modes, challenging and interpreting replies, and selecting mode functions at the remote set control. Officers and Operations Specialists (OS) assigned to the CIC and Air Traffic Controllers (AC) perform these actions during air traffic control operations. The addition of the AN/UPX-XX will be transparent to the operator. Surface ships are capable of operating their MK XII systems on a continuous basis. Basic operational uses of the MK XII are:

    • Anti-Air Warfare using Modes 1, 2, 3/A, and 4 to provide complete identification of airborne platforms.
    • Air Control using Modes 2, 3/A, and C to provide necessary data for control of friendly aircraft.
    • Air Traffic Control using Modes 2 and 3/A for aircraft departure and approach control of carrier aircraft.
    • Surface Identification using Modes 1, 2, 3/A, and 4 for complete identification of friendly surface platforms.
    • Additionally, transponders aboard aircraft can provide special purpose responses to the shipboard interrogator's operator with special audible and visible warnings. These special purpose replies include different emergency codes indicating an aircraft in trouble, or a communications failure and a special reply for position identification manually activated by the aircraft commander upon verbal request.

2. Maintenance Concept. The maintenance concept for the MK XII has evolved from its early days. Then, MK XII equipment was repaired at the organizational level by removing and replacing defective piece parts on plug-in assemblies and Printed Circuit Boards (PCB). The organizational level maintenance concept in the Fleet today has evolved to repair MK XII equipment to the card level by removing and replacing the PCBs and Electronic Modules (EM). Piece part repair of PCBs and EMs is accomplished at the intermediate level of maintenance, via Microminiature (2M) Repair shops. General direction and guidance regarding the maintenance concept for the MK XII is provided by the Issue of Ships Maintenance and Material Management (3M) Manual, OPNAVINST 4790.4 (series). The 3M Manual prescribes the three level maintenance concept: organizational, intermediate, and depot.

a. Organizational. Organizational level maintenance is performed by Electronics Technicians (ET) with Navy Enlisted Classification (NEC) 1572 and consists of preventive and corrective maintenance to the PCB and EM level.

(1) Preventive Maintenance. Preventive maintenance includes built-in-tests (BIT) operational readiness tests, periodic inspections and scheduled maintenance. Preventive maintenance is performed per Maintenance Requirement Cards that are part of the Planned Maintenance System.

(2) Corrective Maintenance. Corrective maintenance includes troubleshooting, measuring, aligning, and repairing by removing and replacing defective PCBs and EMs.

b. Intermediate. Intermediate maintenance activities, ashore and afloat, perform maintenance actions beyond the capabilities of the organizational activities. These actions are performed by ETs with NEC 1572 and include fault verification, fault isolation using Automatic Test Equipment, and repair of MK XII equipment to the PCB and EM piece part level. These actions are performed by 2M repair shops afloat and Fleet Technical Support Centers ashore. Technical assistance and advisory services for the MK XII are provided by the Naval Air Warfare Center, Aircraft Division, Patuxent River, Maryland, St. Inigoes Detachment IFF Systems Branch.

c. Depot. All repairable assemblies beyond the capabilities of intermediate level maintenance are forwarded to the Space and Naval Warfare Systems Command Systems Center, San Diego, California for repair and restoration. Depot level maintenance on the KIR-1C/TSEC and KIT-1C/TSEC is performed at designated crypto repair facilities.

d. Interim Maintenance. NA.

e. Life-Cycle Maintenance Plan. There is no singular depot level maintenance plan encompassing the many pieces of equipment that make up the different configurations of the MK XII systems. However, all failed repairable MK XII components beyond the capability of intermediate level repair are forwarded to designated depot level repair sites.

3. Manning Concept. Operator manpower requirements for the MK XII are determined by the CIC and air operation requirements for each class ship. There are no operator or watchstation billets specifically dedicated to the MK XII System. Maintenance manpower requirements are driven by the total maintenance workload for a specific configuration aboard a specific ship. The billet structure currently supporting the MK XII will not change as a result of this NTSP.

4. Training Concept. The overall objective of the MK XII training program is to provide a ready supply of trained maintenance technicians to the fleet. MK XII training is established at Fleet Training Center (FTC) Norfolk, Virginia. In 1997, the AIMS MK XII IFF Systems Maintenance course, A-102-0062, underwent a Surface Warfare Technical Readiness Review and the Training Course Control Document was revised. As a result, the course content was streamlined and the length reduced from 22 to 16 weeks. The revised course was Ready For Training (RFT) in July 1997. The addition of the AN/UPX-XX information to the MK XII course curriculum will not change course length. The MK XII Maintenance course with AN/UPX-XX information included is scheduled to be RFT in April 2000.

a. Initial Training. Initial training for the original MK XII equipment was completed over two decades ago. As new equipment and new versions of equipment that differed significantly from those superseded were developed, initial operators and maintenance training was provided to instructors to ensure technical integrity of follow-on training.

The contractor will provide initial AN/UPX-XX Digital Interrogator operator and maintenance training to government DT&E, OT&E, and the initial cadre of fleet personnel. Initial training for DT&E personnel will be completed prior the start of DT&E, scheduled to begin in third quarter FY99. Initial training for OT&E and cadre fleet personnel will be completed prior to the start of OT&E, scheduled to begin in first quarter FY00. More information concerning initial training will be added to future updates to this NTSP as it becomes available.
