F-18 Series

The F-18 Series Modification Program is a comprehensive line item within the Navy's Aircraft Procurement budget, focused on the modernization, safety, and capability enhancement of all models of F/A-18 and EA-18G aircraft. The overarching objective is to ensure these platforms remain operationally relevant, safe, and interoperable with current and future mission requirements. The program encompasses a wide array of modifications, including avionics upgrades, electronic warfare enhancements, training system improvements, integration of advanced targeting and communication systems, and service life extension initiatives. These efforts are managed by the Naval Air Systems Command (NAVAIR) and are essential for maintaining fleet readiness and supporting the evolving needs of both the Navy and Marine Corps aviation units.

Joint Helmet Mounted Cueing System (JHMCS) (OSIP 24-00) aims to address legacy helmet system obsolescence and improve aircrew safety and situational awareness. The Improved JHMCS is being integrated into F/A-18E/F and EA-18G aircraft to reduce weight, improve center of gravity, and mitigate chronic injury risks. The system provides high-definition, day/night displays of critical flight and tactical data, replacing older helmet and night vision devices. This upgrade streamlines aircrew tasks, enhances weapons cueing capabilities, and supports real-time tactical decision-making.

Advanced Targeting Forward Looking Infrared (ATFLIR) (OSIP 12-01) provides advanced infrared and visible spectrum targeting capabilities to F/A-18 and EA-18G aircraft. The program supports detection, tracking, and engagement of targets at extended ranges, with ongoing upgrades to pod performance, reliability, and network-centric operations. Recent efforts include encrypted multi-band data link modernization and software improvements to support evolving mission profiles and interoperability with ground controllers.

Core Avionics Improvements/Upgrades (OSIP 023-04) focus on retrofitting avionics systems to address obsolescence, improve reliability, and enhance mission planning capabilities. Major objectives include the transition to an Advanced Cockpit System (ACS), integration of high-speed digital video recorders, and continuous software modernization through an Agile framework. This approach enables frequent, incremental software releases, ensuring rapid delivery of new capabilities to the fleet and improved cyber and information assurance.

AESA/AN-APG-65/AN-APG-73 Radar Upgrades (OSIP 002-07) support the integration and enhancement of radar systems, including the APG-79 AESA radar. These upgrades improve threat detection, ground mapping, and electronic warfare capabilities. The program also addresses radar component obsolescence, introduces wideband receiver systems for advanced electronic attack, and implements agile software integration to keep pace with emerging threats and mission requirements.

EW Unique (OSIP 021-08) funds the procurement and retrofit of the Advanced Electronic Warfare suite (ADVEW) for Block III Super Hornets, replacing legacy radar warning receivers and jammers with a modern, automated EW processing architecture. The suite enhances both offensive and defensive capabilities, supports interoperability across the Carrier Air Wing, and integrates new survivability equipment. Funding initiates low-rate initial production following successful prototyping and testing milestones.

Network Centric Operations (OSIP 001-10) seeks to standardize networked avionics across all F/A-18 and EA-18G aircraft, improving mission performance, interoperability, and survivability. Key upgrades include distributed targeting processors, precision approach and landing capabilities, and advanced GPS receivers. The program also supports compliance with future navigation mandates and ensures the aircraft can operate effectively in joint and contested environments.

Priority Stores Integration (OSIP 10-16) enables F/A-18E/F and EA-18G aircraft to carry and employ a broader range of air-to-air and air-to-ground weapons. The program funds software and hardware modifications required for new and upgraded weapon systems, ensuring mission flexibility and safety. It also supports engineering, logistics, and verification activities necessary for integrating future weapons and maintaining compatibility with evolving fleet requirements.

Physiological Episode (PE) Mitigation (OSIP 13-19) addresses aircrew safety by funding modifications to life support and environmental control systems. Efforts include hardware and software upgrades to oxygen generation and cabin pressurization systems, enhanced monitoring and alerting, and integration of new emergency oxygen solutions. These changes are designed to reduce the risk of physiological incidents and improve overall flight safety.

Communication Systems (OSIP 11-21) focuses on secure, resilient, and interoperable communications for F/A-18E/F and EA-18G platforms. Upgrades include the Multifunctional Information Distribution System (MIDS) Joint Tactical Radio System, Tactical Targeting Network Technology (TTNT), Global Lightning Beyond Line of Sight (BLOS) capability, and next-generation SATCOM radios. These enhancements support joint and multi-domain operations, ensure cryptographic modernization, and provide real-time data exchange for command and control and targeting.

EOIR Modernization (OSIP 003-24) provides F/A-18E/F aircraft with advanced electro-optical and infrared targeting capabilities. The program incorporates non-developmental targeting pods and technology upgrades to improve reliability, maintainability, and mission effectiveness. Funding supports procurement of LITENING POD Artemis kits and associated integration efforts, in response to operational requirements set by Commander Naval Airforce.

Service Life Modifications (SLM)/Block III (OSIP 14-26) funds comprehensive upgrades to extend the operational life and enhance the capabilities of F/A-18E/F Block II aircraft transitioning to Block III. Modifications include installation of the Advanced Cockpit System, distributed targeting processors, network infrastructure wiring, and structural improvements. These upgrades address technology obsolescence, improve survivability, and ensure the aircraft remain mission-capable through 2040.
