Description
Mission — H-1 Improvements
The objective of H-1 Improvements is to provide follow-on Research, Development, Test and Evaluation efforts in support of all H-1 aircraft. Air Vehicle and Engine improvements include analysis of structural data to formulate Damage Limits and Tolerances for structural components in order to reduce life cycle costs and maintenance workload; development and test of structural components. These improvements include tail boom, fuselage, and airframe components, minimizing excessive and premature wear, increased reliability, decreased component fatigue and improve existing design deficiencies. Air Vehicle aircraft components will develop solutions to develop an auxiliary fuel cell capability and Rotocraft Station Control Unit (RSCU) Software development. RSCU efforts will encompass software development, testing, cybersecurity, and acquisition of test assets. All air vehicle and engine improvements include related Software Configuration Set (SCS) development updates and address hazard reports including software, test assets, cybersecurity, and testing. Avionics improvements target digital inter-operability, integrated avionics, safety and survivability, and situational awareness for both the pilot and aircrew safety. This includes Degraded Visual Environment (DVE), cockpit displays, precision and Global Positioning System (GPS) non-precision landing capability, collision avoidance, improved Embedded Global Positioning System (EGI), Radar Altimeter (RADALT), Inertial Navigation System (INS), Health and Monitoring System Upgrade (HMU), and mission computer software development. H-1 capability improvements include improved digital operations and transfer of data, digital interoperability, digital video recording, video and data networking, and information integration with aviation combat elements and Marine Air Ground Task Force elements. Mandated capability efforts include - Communications and COMSEC modernization to include Tactical Secure Voice/Second generation Anti-Jam Tactical Ultra-High frequency Radio for NATO (TSV/SATURN), Navigation and Surveillance system/Air Traffic Management (CNS/ ATM), Required Navigation Performance/ Area Navigation (RNP/RNAV), Automatic Dependent Surveillance - Broadcast (ADS-B), Crash Survivable Flight Incident Recorder and information technology/protection of the platform. Mobile User Objective System (MUOS) allows the H-1 to retain satellite communication capabilities. Efforts include the integration and test of Beyond Line of Sight (BLOS) satellite systems. Digital Interoperability (DI), the expansion of DI to include integration of Adaptive Network Wideband Waveform (ANW-2), Net enables weapons control, Integrated Aircraft Survivability Equipment (iASE), leveraging Proliferated Low Earth Orbit (pLEO) communications, advanced Flite Scene mapping and mission planning updates shortens the kill chain and improves information and intelligence sharing on the battlefield. DI incorporates a family of systems that includes ANW-2, Advanced Data Transfer System (ADTS), Full Motion Video (FMV), Radio Frequency Identification (RFID), Small Tactical Terminal (STT), and Cross Domain Solution (CDS). Improvements to address hazard reports against avionic platform systems which may include attitude trim performance, flight control systems performance, communication and navigation systems performance, data link and waveform systems performance, display and recorder systems performance, and aircraft health data system performance. All avionics improvements include related SCS development updates and address hazard reports including software, test assets, cybersecurity, and testing. Sensors, Weapons, Aircraft Survivability Equipment (ASE), and Helmet Mounted Display System improvements include manufacturing process improvements, hardware and software redesign to improve reliability, improve production methodologies, implement program security initiatives and increase the collective capability to address emerging battlefield threats. These improvements address reliability and obsolescence. The technical interfaces between the aircraft sensor, helmet, and weapons systems require extensive software and hardware upgrades to translate data into sensor fusion based solutions that provide both battlefield and situational awareness to the H-1 platform. The AN/AAQ-30 Target Sight System (TSS) will implement several obsolescence upgrade efforts with improvements to the Cameras as well as adding software driven capabilities such as increased field-of-views and auto-focus. The BRITE Star Block II Target Location Error correction will be completed. The Optimized TopOwl (OTO) reliability upgrades will increase reliability and readiness for components that are currently driving high repair costs. Aircraft Survivability Equipment systems including the APR-39D(V)2, Distributed Aperture Infrared Countermeasures (DAIRCM) and the AN/ALE-47 Common Carriage expendables, which require extensive integration and testing. Funds required for development, test, and integration efforts for Precision Attack Strike Munition (PASM), Joint Air-to-Ground Missile (JAGM), AGM-114 Hellfire, Advanced Precision Kill Weapons (APKWS), Modular Common Launcher, M299 Launcher improvements, Digital Rocket Launcher (DRL), AIM-9X, and AN/ALQ-231 (V) Intrepid Tiger II Electronic Warfare Pod. Improving and integrating weapon systems and expendables will align with these upgrades to improve the overall accuracy, lethality, and survivability of the H-1 platform. Improvements to address hazard reports against sensors and weapons platform systems which may include helmet and display systems performance, sensor systems performance, and weapon systems performance. All weapon and sensor improvements include related OFP development updates and address hazard reports including software, test assets, cybersecurity, and testing. These improvements will provide considerable growth potential for future weapon systems, air vehicle improvements, software improvements, and avionics upgrades, which will significantly increase mission effectiveness and survivability, while potentially reducing life cycle costs. The efforts will also include integration of onboard mission planning, communications, digital fire control, self-navigation, night navigation/targeting, precision guided munitions, and air-launched intercept missile weapon systems management in nearly identical crew stations, which significantly reduces training requirements. These upgrades maximize commonality between all H-1 Type/Model/Series aircraft and provide needed improvements in crew and passenger reliability, survivability, payload, power available, endurance, range, airspeed, maneuverability and supportability.
Mission — H-1 UPGRADES
The mission of the AH-1 attack helicopter is to provide rotary wing close air support, counter unmanned aerial system (UAS), counter maritime, anti-armor, armed escort, armed/visual reconnaissance, survivability enhancements, and fire support coordination capabilities under day/night and adverse weather conditions. The mission of the UH-1 utility helicopter is to provide command and control and combat assault support under day/night and adverse weather conditions and special operations support; supporting arms coordination and aeromedical evacuation. Major modifications for both aircraft include 37 AH-1Ws converted to AH-1Zs, build 152 new AH-1Zs, remanufacture ten (10) H-1N helicopters and build 150 new UH-1Y models. AH-1Z and UH-1Y models include a 4-bladed, composite rotor system with semi-automatic bladefold, performance-matched transmissions, T700 Engine Digital Electronic Control Units, 4-bladed tail rotors and drive systems, more effective stabilizers, upgraded landing gear, and common, fully integrated cockpits and avionics systems. These upgrades add 10,000 flight hours to AH-1Z/UH-1Y airframes. The fully integrated cockpits reduce operator workload and improve situational awareness, thus increasing safety and reducing the rate of aircraft attrition. They provide considerable growth potential for future weapon systems and avionics to significantly increase mission effectiveness and survivability. The cockpits also include integration of onboard mission planning, communications, digital fire control, self-navigation, night navigation/targeting, air-to-ground missile and air-launched intercept missile weapon systems management in nearly identical crew stations, which significantly reduces training requirements. These upgrades maximize commonality between the two aircraft and provide needed improvements in crew and passenger survivability, payload, power available, endurance, range, airspeed, maneuverability and supportability. This budget is required for follow-on improvements to H-1 aircraft via integration of sensors and weapons, avionics, and air vehicle components that will address deficiencies, systems safety, obsolescence, readiness, reliability, supportability, and relevance in the battlespace. Improvements will include all associated System Configuration Set (SCS) updates and address hazard reports against air vehicle and engine, sensors and weapons, and avionics components, systems, and subsystems, training, and aircrew systems as well as integration and testing related to the aircraft platforms. This program is funded under SYSTEM DEVELOPMENT AND DEMONSTRATION because it includes those projects that have passed Milestone B approval and are conducting engineering and manufacturing development tasks aimed at meeting validated requirement prior to full-rate production decision.
