1. General Description of Operational Capability

a. Mission Area. This requirement relates to the Office of the Under Secretary of Defense (Acquisition) Mission Areas 212 (Indirect Fire Support), 217 (Land Warfare Surveillance and Reconnaissance), 223 (Close Air Support and Interdiction), 232 (Amphibious, Strike, and Anti Surface Warfare), 237 (Naval Warfare Surveillance and Reconnaissance), 322 (Tactical Intelligence and Related Activities (TIARA) for Tactical Land Warfare), 345 (Tactical Communications), 370 (Electronic Combat), and 373 (Tactical Surveillance, Reconnaissance, and Target Acquisition).

b. System Description. The Vertical Takeoff and Landing Tactical Unmanned Aerial Vehicle (VTUAV) system will be compatible with the Tactical Control System (TCS), and consist of Air Vehicles (AV), Ground Control Stations (GCS), Ground Data Terminals (GDT), Remote Data Terminals (RDT), Modular Mission Payloads (MMP) and tactical communications devices.

c. Operational Concept

(1) The Naval White Letters Forward...From the Sea and Operational Maneuver From the Sea (OMFTS) provide direction to the U.S. Navy (USN) and the U.S. Marine Corps (USMC) concerning the challenges of the post-Cold War world and shifts the operational focus of naval forces from the open ocean to the world's littorals. The White Letters introduce the concept of Littoral Warfare, and emphasize the capability of naval forces as a forward deployed crisis response force to deter conflict in the littorals, and to prevent escalation and restore stability where deterrence has failed.

(2) The VTUAV system will be located in Unmanned Aerial Vehicle (UAV) squadrons within the USN and USMC. It will be a replacement for the Pioneer UAV system. When required, individual detachments or partial VTUAV systems may be combined to support protracted operations or to meet high demand tasking, afloat or ashore. In order to overcome potential line-of-sight (LOS) problems that may arise as a result of conducting operations ashore and to provide maximum operational flexibility, the capability to conduct split site operations is required for all systems.

(3) The VTUAV system will be TCS compliant and use Service standard computer based GCSs to perform detailed mission planning and mission execution. AVs, carrying MMPs, either manually controlled by a GCS or executing a preprogrammed route, will fly to areas of interest typically predetermined by intelligence preparation of the battlefield or cueing from other systems. Information received by the GCS will be processed, analyzed and synthesized as necessary for dissemination via radio networks, Service local area networks, or existing Service C4I systems.

d. Support Concept

(1) USN/USMC. The VTUAV system shall abide by the guidance of the Naval Aviation Maintenance Program (NAMP). Each deployable VTUAV system must be provisioned so as to be capable of extended operations (greater than 30 days) without resources external to those carried by the host ship. Intermediate and depot level maintenance will not be readily available onboard most aviation capable ships.

(2) USMC Land-based. When land-based, the VTUAV system detachment's organizational maintenance capability will be compatible with USMC organizational transportation assets carrying sufficient test equipment and parts to support operations for an initial 72 hour period.

e. Mission Need Statement (MNS)

(1) Joint Requirements Oversight Council Memorandum (JROCM) 003-90, dated January 1990, validated the MNS for a Close Range Reconnaissance, Surveillance, and Target Acquisition (RSTA) Capability.

(2) Tactical Vehicle Reconnaissance/Surveillance and Target Acquisition (TVRSTA) Capability MNS, approved by the Assistant Commandant of the Marine Corps, 6 January 1998.

(3) The USN Vertical Takeoff and Landing Integrated Platform for Extended Range Reconnaissance Unmanned Aerial Vehicle (VIPER UAV) Operational Requirements Document (ORD), dated 19 February 1992, validated the USN requirement for a VTOL capable UAV.

2. Threat. The VTUAV system is expected to provide support across the operational continuum from Military Operations Other than War to high-intensity conflict.

a. Threat to be Countered. The VTUAV system will be exposed to direct and indirect threats; the level of threat is scenario dependent. Further, the range of weapons to be used against the VTUAV system will vary from region to region, country to country.

(1) Direct Threats. Those threats which can damage or destroy the AV in-flight, including surface-to-air missiles and air defense artillery. Fighter aircraft and helicopters armed with air-to-air missiles pose a secondary threat to the AV. Furthermore, the GCS may be threatened by attacks with radiation-homing missiles, artillery and surface-to-surface missiles.

(2) Indirect Threats. Those threats which can reduce mission effectiveness and include Information Operations (IO) and Electronic Warfare (EW). The VTUAV sensors may be vulnerable to jamming, spoofing, and camouflage, concealment, and deception (CC&D). Data/communication links may be vulnerable to jamming, disruption, and deception. In addition, lasing and subsequent damage of VTUAV's optical sensors is also a possibility.

b. Projected Threat Environment. Projected threats to VTUAV system are described in the following publications:

(1) Expeditionary Warfare Threat to Environment Projections, Vol 1 - 3 (U). Provides a baseline threat in support of the Marine Corps weapon systems acquisition programs and developments.

(2) Vol 1: Command, Control, Communications, Computers, and Intelligence (C4I), C4I Support, and Electronic Warfare (U) MCIA-1527-001-98, (U) May 98. Specifically addresses threat technologies and innovations which may adversely affect USMC C4I and EW operations.

(3) Vol 2: Antiair (U), MCIA-1543-001-98, Aug 98. Addresses threat technologies and innovations of concern to USMC air defense assets.

(4) Naval Strike and Air Warfare Systems (U), ONI-TA-017-98, Jan 98. Provides the threat assessment foundation to assist in determining future tactical strike and air warfare program requirements and for use in deriving threat statements for program documentation.

(5) Worldwide Threat to U.S. Navy & Marine Forces, 1997 - 2017, Volume I and II (U), ONI-1200-001-98, Oct 97. Provides an overall description of the extensive ranges of threats along the littorals.

(6) System Threat Assessment Report for the Joint Tactical Unmanned Aerial Vehicle, Sep 95.

3. Shortcomings of Existing Systems

a. Pioneer. Production and fielding of the Pioneer UAV system was stopped in 1988 with minimal subsequent funding provided for system sustainment. While upgrades to the Pioneer UAV systems are planned to increase current capabilities until a suitable replacement is fielded, these upgrades will not provide the combat radius, payload capacity, speed, or endurance required to support emerging concepts for operations in the littorals or during sustained operations ashore. Current and projected deficiencies include:

(1) Limited shipboard compatibility:

(a) Disrupts flight operations.

1 Requires the clearing of the flight deck for launch and recovery.

2 Requires a rocket-assisted takeoff.

3 Requires a net or arresting gear for recovery.

(b) Does not have a heavy fuel engine.

(2) Number and size of MMPs are limited by AV payload capacity, AV engine power available and AV electrical power generating capability.

(3) Obsolete and system-unique GCSs.

(4) Inadequate speed.

b. Medium Altitude Endurance (MAE) UAV. The Predator MAE system, although not organic to Naval Forces, has the range, endurance, and payloads required to support littoral operations. Other limitations of the Predator UAV include:

(1) No shipboard compatibility:

(a) Unable to launch and recover on air capable ships.

(b) No heavy fuel engine.

(2) Inadequate speed.

(3) Requires host nation support to forward deploy.

(4) C-band LOS datalink will not be compatible with future battlegroup Radio Frequency (RF) spectrum usage.

(5) Predator MAE systems are normally employed as theater level assets.

4. Capabilities Required

a. System Performance

(1) Mission Scenarios and Employment Tactics

(a) USN

1 VTUAV Detachments will provide commanders near-real time imagery and data required to support Intelligence, Surveillance and Reconnaissance (ISR) requirements independent of, or in concert with, the use of manned aircraft or reliance on limited Joint Theater or National Assets. Specific missions supported by the VTUAV system include: an embedded ISR, Over-The-Horizon Classification, and Targeting for naval surface fire support/air warfare. Other growth mission areas will be pursued utilizing the JROC chartered, UAV Special Study Group's Mission Prioritization Report for guidance.

2 The VTUAV will be an organic asset of the Battle Group Commander or ship to which it is attached/deployed. Typically, the VTUAV will launch and proceed to a designated mission area by flying directly to or through a series of preprogrammed waypoints. Upon entry into the mission area, control of the AV and MMP may be turned over from the primary operator to a mission specific operator or the AV and MMP may execute a preprogrammed loiter command about the target area. Upon completion of the mission, the AV may return to the launching ship, another air capable ship, or ashore for recovery.

(b) USMC

1 The VTUAV system will provide the Marine Corps the capabilities required to conduct littoral operations in support of OMFTS. The VTUAV's range, endurance, and communications and information systems (CIS) will provide the Marine Air-Ground Task Force (MAGTF) commander with a means to enhance his situational awareness, assist in the engagement of threat forces, exercise command and control, and assess the results of ongoing activities. The VTUAV system will perform a variety of functions including reconnaissance, surveillance, target acquisition, target designation, communications and data relay, electronic warfare, and delivery of non-lethal weapons and remote sensors. The VTUAV system capabilities will assist the MAGTF by executing missions from significant standoff distances as called for in OMFTS. These capabilities will enhance the MAGTF's ability to conduct operations across the spectrum of conflict, to include Military Operations Other Than War as well as to function in a wide variety of environments to include urban terrain, mountains, deserts, and jungles. The VTUAV system should have growth capability to support other evolving mission requirements.

2 The VTUAV's ability to rapidly deploy aboard and operate from all air capable ships will provide the flexibility required to meet the needs of tactical commanders at all levels of the MAGTF. The VTUAV system will be deployed as an organic asset of the MAGTF commander for both general and direct support.

The VTUAV system will have a BIT capable of isolating failures to the Line Replaceable Unit (LRU) or repairable, reconfigurable and reprogrammable items. The BIT shall identify and store faults for maintenance recall on demand and provide operators with a reliable and comprehensive check of system operational status for a mission go/no go determination prior to flight. The VTUAV system shall require the same or less organizational manpower and mobilization packup as the Pioneer UAV system.

(3) VTUAV System Operational Suitability Requirements

(Table 1).


Availability Operational Availability (Ao) (Note 1,2) 85%/ 95%

Reliability Mean Flight Hours between Operational Mission Critical Failures (MFHBOMCF)

(Note 1,3,4)

30 hrs/ 90 hrs


(Contd.) Mean Flight Hours Between Unscheduled Maintenance (MFHBUM) (Note 1,3,5) 24 hrs/ 36 hrs

Maintainability Mean-Time-To-Repair (MTTR) (Note 4,6)

ú 2.0 hrs/ú 1.0 hrs

Repairability Avionics Fault Detection Rate (FDet) (Notes 3,7,8)

Avionics Fault Isolation Rate (FI) (Notes 3,7,9) 75%/ 89%

85%/ 100%


1. During developmental and/or operational testing it may not be feasible to operate the VTUAV system sufficiently to develop a statistically meaningful data base for Ao, Maintainability, and Reliability values (i.e. if 1 of 5 events are negative, the one negative outcome may be the first one measured; therefore percentages shown in Table 1 cannot be fairly evaluated unless 5 events are observed). Consequently, extrapolation from laboratory testing and maintenance demonstrations (M-DEMOs) will substitute for the lack of available flight test data to evaluate VTUAV system upgrade ability to satisfy these requirements. Actual fleet data should satisfy these requirements by IOC plus one year.

2. Ao will be calculated using the following formula:



Operational Availability covers all time segments the system is intended to be operational. Operational Availability is based on a mathematical relationship among three characteristics: reliability, maintainability, and the effectiveness of the logistics support system. Reliability is as the mean operating time plus mean standby time in an operational condition (represented by Mean Time Between Maintenance (MTBM)). Maintainability includes the mean maintenance time for both corrective and preventive actions (represented by Mean Maintenance Time (MMT)). Logistics support effectiveness is the combination of the logistics delay time plus any administrative delays (represented by Mean Logistics Down Time (MLDT)). The Mean Time Between Maintenance (MTBM) is based on all maintenance actions, whether corrective or preventative in nature.

3. Operation reliability is measured by mean flight hours between mission critical failures of the VTUAV System (MFHBMCFLRU), which includes mission critical hardware and software failures.

4. An operational mission failure (OMF) is a hardware failure or software fault that prevents the system from performing its intended mission. MFHBOMF will be calculated using the following formula:

MFHBOMF = Total flight hours

Total number of operational mission critical failures

5. MFHBUM will be calculated using the following formula:

MFHBUM = Total flight hours

Total number of unscheduled maintenance actions

6. MTTR is the average elapsed organizational level maintenance time needed to repair all operational VTUAV system hardware failures. It includes fault location and isolation, access time, fault correction, adjustment and calibration and follow-up checkout time. It does not include maintenance preparation, on-board and off-board logistic delay time.

7. During developmental and/or operational testing it may not be feasible to fly the sufficient amount of hours required to develop statistical meaningful data bases for FDET and FI values (Note 1).

8. FDET will be calculated using the following formula:

FDET = Total number of failures correctly detected by BIT

Total number of actual system failures

9. FI will be calculated using the following formula:

FI = Total number of failures correctly isolated to faulty LRU

Total number of failures correctly detected by BIT

c. Other System Characteristics

(1) Survivability. Survivability, Electronic Countermeasures (ECM)/Electronic Counter-countermeasures (ECCM) and low observable technologies will be considered in the design of the VTUAV system.

(2) Nuclear, Biological, and Chemical (NBC) Contamination. The system and support equipment must be compatible with current individual protective equipment and capable of being operated, maintained, and resupplied by personnel in Mission Oriented Protective Posture (MOPP) IV. System electronic components require neither nuclear hardening nor NBC decontamination survivability. The VTUAV system must be capable of NBC decontamination with Service standard decontamination equipment.

(3) Responsiveness. (Timelines are not applicable in an NBC environment).

(a) A VTUAV system must be capable of being off-loaded from its transport vehicles and achieving, at a minimum, Mission Capable (MC) status, i.e. one GCS and one AV with basic AV components, within 60 minutes (Threshold)/30 minutes (Objective).

(b) After a VTUAV system has achieved at a minimum, MC status, it must:

1 Be capable of launching a single AV within 30 minutes of receipt of tasking, assuming prior airspace coordination and mission planning have been completed (Threshold).

2 Be capable of being disassembled, made ready for transport, and reloaded aboard its ground transport vehicles within 60 minutes or less (Threshold).

3 Be capable of being fully integrated into the shipboard flight operations typically associated with the launch and recovery of helicopters and other conventional/VTOL aircraft from all air capable class ships. Specifically, the AV must be capable of launching within 10 minutes or less (Threshold)/5 minutes or less (Objective) after being positioned on its launch point on the flight deck. Following its recovery, the AV must be capable of being moved from the flight deck to its storage point in 10 minutes or less (Threshold)/5 minutes or less (Objective).

(4) Electromagnetic Environmental Effects (E3). The individual communication-electronic (C-E) equipment/subsystems utilized on the VTUAV system shall be intra-system/platform electromagnetically compatible to ensure that system/platform operational performance requirements are met. The performance of the VTUAV system shall not be degraded when exposed to its operational electromagnetic environment (natural or man-made).

a. Maintenance Planning. A Level of Repair Analysis (LORA) will be conducted for the VTUAV system to determine the most cost effective maintenance concept. At the Initial Operational Capability (IOC) date, the total system will be maintained as indicated by the LORA to the maximum extent feasible. In order to meet the IOC schedule, intermediate level maintenance, if required by the LORA, will not be demonstrated during Operational Evaluation (OPEVAL). At the Full Operational Capability (FOC) date, the system will be fully supported as indicated by the LORA.

b. Support Equipment (SE). If SE is required, design considerations should allow maximum use of common SE, minimizing the use of unique support equipment. Any required SE shall have diagnostic and fault isolation capability to facilitate troubleshooting, repair and/or replacement of components. Organizational level SE shall be capable of providing comprehensive end-to-end verification/validation of system operability. If I-level or D-level maintenance requirements for the VTUAV system require the use of automated test equipment (ATE), then ATE will be selected from the approved DoD family of testers. The probability of test equipment fault detection and confidence levels are defined in Table 1 of section 4.b.(3).

c. Human System Integration

(1) Manpower Requirements. A Manpower, Personnel, and Training (MPT) analysis will be conducted to recommend options to exploit technology to reduce MPT requirements. Results will be documented in a USN Training Plan and must not exceed current Pioneer UAV system manning levels. The VTUAV system must be maintained with skills resident within the squadron.

(a) Unit Training. Computer Based Training will be maximized for operator and maintenance personnel. Maintenance personnel shall initially be trained by contractor, government development test personnel or a government/contractor team with an approved training course. Organic maintenance training shall start no later than 90 days after IOC.

1 Operator and maintainer embedded and add-on interactive training, with self-paced instruction, duplicating VTUAV system flight performance characteristics, capabilities, and limitations are required (Objective).

2 Simulators and training devices will maximize training effectiveness while minimizing the impact of actual flight hours on equipment. Simulators shall have an embedded simulation capability that fully emulates all functions required to operate both the air vehicle and MMP, with a growth capability for new MMPs.

(b) Technical Manuals (TM). TMs, in accordance with the NAMP, will be required to provide operator information and maintenance procedures.

(2) Environmental, System Safety and Health Hazard Assessment. The design of the VTUAV system shall address environmental, safety and health requirements, and the design shall consider the life-cycle costs of maintaining the environmental, safety and health factors of the system.

d. Computer Resources. The system must be capable of providing a 50 percent (Threshold)/75 percent (Objective) growth potential over delivered capability.

e. Other Logistics Considerations. A Supportability Analysis (SA) shall be performed to address any peculiar logistics concerns of the VTUAV system and its SE. The SA shall ensure support considerations are integrated into system and equipment design and that repair level decisions are based on an operationally sound and cost effective design. A comprehensive SA database shall be developed to ensure maximum use of automated SA reports for determining and budgeting for logistics support resources.

f. Command, Control, Communications, Computers, and Intelligence (C4I)

(b) Electrical Power. VTUAV system ground components must be compatible with standard electrical power available within the DoD family of mobile electric power sources. The system must be capable of restoring power in sufficient time to avoid loss of mission critical data or loss of AV control during intermittent power outages. The system will not rely on the prime movers as a primary power source; however, prime movers may be used as an emergency or backup power source. Operators will be able to adapt the system to standard worldwide commercial alternating current power (120 volts/60 hertz and 220 volts/50 hertz). VTUAV systems deployed aboard ships must be capable of using ship's power or deck edge power, with an uninterruptable power supply (UPS) as the backup power supply (Threshold).

k. Environmental Support. The VTUAV system shall be capable of receiving standard meteorological information from the appropriate aviation command element or ship's weather department (Threshold).

6. Force Structure

a. USMC. Requires eleven VTUAV systems (four AVs per system) to meet pre-positioning, war reserve, and expeditionary force requirements. Distribution will be as follows:

VMU-1 will have four systems.

VMU-2 will have four systems.

Maritime Pre-positioned Ships will have three systems.

(1) USMC Land-based VTUAV System. Consists of:

(a) Four AVs.

(b) Air vehicle SE as required.

(c) Four MMPs as defined in this ORD.

(d) Two land-based data link systems consisting of a man-portable or trailer-portable antenna(s), receiver(s), transmitter(s), and cabling required to connect the data link system to the GCS.

(e) Two land-based GCSs (TCS core software) with Data Control Modules (DCM), consisting of a HMMWV portable shelter to house the host computers of the TCS software and a fully integrated communications suite for AV C2. The communications suite consists of the radio assets listed in this ORD and integrates the radios with the ICS to enable the operators to select either radio or ICS communications on the same system.

(f) Two RDTs (TCS core software).

(g) Additional mission specific MMPs (as required).

b. USN. Initially requires twelve VTUAV systems, plus additional VTUAV systems based upon an Analysis of Requirements for VTUAV systems. The TCS Shipboard Integration Study will determine the number of ships and level of capability/interoperability required for TCS integration. The USN Sea-based VTUAV System will consist of:

(1) The same numbers of AVs, air vehicle SE and MMPs as the USMC VTUAV land-based system, and any additional AVs to meet specific mission requirements.

(2) One land-based data link system.

(3) One sea-based data link system consisting of the antenna(s), receiver(s), transmitter(s), and cabling compatible with all air capable ships.

(4) One land-based GCS (TCS core software) with DCMs.

(5) One sea-based GCS (TCS core software) with DCMs consisting of two or more racks of computer equipment to be mounted/installed aboard the ship.

(6) Two RDTs (TCS core software).

(7) Additional mission specific MMPs (as required).

c. U.S. Army. The Army may require a VTUAV system(s) to meet projected future Corps and Division TUAV requirements.

d. Training. Additional systems required to support the Joint DoD UAV Training Center will be identified at a later date.

7. Schedule Considerations

a. IOC. IOC is achieved after each Service has fielded one production representative system with Integrated Logistics Support (ILS) procurement (training, spares, technical publications) in place and developmental and operational testing completed. The level of performance necessary to achieve IOC requires one system in a final configuration with operators and maintenance personnel trained and initial spares with interim repair support in place.

(1) IOC. Fourth Quarter, FY03.

(2) Impact if IOC is Not Met. The Pioneer UAV system will require a substantial and costly service life extension if a suitable replacement is not fielded. Also, a robust UAV system capable of supporting tactical commanders with reliable, dedicated, and organic intelligence gathering capability will be delayed.

b. FOC. FOC will be achieved when all maintenance and repair support, software support, test equipment and spares are in place and the systems are effectively employable.

(1) FOC. Third Quarter, FY05.

(2) Impact if FOC is Not Met. Same as the IOC rationale.
