Common Avionics Changes

The Common Avionics Changes program, funded under Navy Aircraft Procurement (Line Item 0577), is designed to modernize, sustain, and enhance the avionics capabilities of multiple naval aircraft platforms. The program's overarching goal is to ensure that common avionics systems such as navigation, communication, mission computing, and interoperability solutions remain compliant with evolving operational requirements, regulatory mandates, and technology standards. This line item supports both procurement and modification activities, integrating new hardware and software across diverse aircraft types. It also addresses obsolescence, reliability, and readiness challenges.

Global Positioning System (GPS) (OSIP 71-88) funds the procurement and integration of highly accurate GPS equipment for naval aviation platforms. The objective is to provide reliable position and timing data in all weather conditions, supporting navigation, communication, and weapons systems. The program includes anti-jam technologies to protect GPS functionality against interference and jamming. It ensures compliance with DoD mandates for GPS equipage in the National Air Space System, with tailored hardware configurations for each aircraft model. Major milestones include full-rate production of anti-jam antennas and integration into platforms such as the F/A-18E/F, EA-18G, UH-1Y, and AH-1Z.

Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) (OSIP 21-01) supports civil and military airspace compliance through upgrades to communication, navigation, and surveillance systems. The program's goals are to facilitate global airspace access, enable GPS-based routing, and ensure operational safety and efficiency. Key functionalities include Mode S transponders, ADS-B, Required Navigation Performance, and Reduced Vertical Separation Minimum. CNS/ATM modifications are prioritized based on platform mission profiles and anticipated airspace operations, with upgrades planned for AH-1Z/UH-1Y, CMV-22B, EA-18G, E-2D, F/A-18E/F, F-35B/C, MQ-4C, MQ-8B/C, MQ-25A, and P-8A.

Avionics Component Improvement Program (AvCIP) (OSIP 11-09) is focused on resolving critical readiness degraders, reliability deficiencies, and obsolescence issues in naval avionics systems. AvCIP selects candidate projects annually based on solution maturity, urgency, and fleet impact, funding non-recurring engineering, testing, and documentation for component upgrades. The program aims to reduce fleet maintenance costs and improve operational availability by inserting modern technology and supporting alternative component procurements. AvCIP is a cost-wise readiness initiative under the Naval Aviation Enterprise, with project selection and execution managed through a rigorous panel review process.

Secure Communications (OSIP 10-19) modernizes secure UHF/VHF radio systems for both Line of Sight and Beyond Line of Sight communications, including cryptographic modernization and anti-jam waveform integration. The program addresses vulnerabilities in legacy analog systems, implements digital encryption, and ensures compliance with NSA cryptographic mandates. Secure Communications enables robust, secure voice and data connectivity, supporting new waveforms such as MUOS, SINCGARS, and SATURN. Installation efforts are prioritized based on platform schedules and operational needs, with modifications spanning platforms including UC-35, KC-130J, CH-53K, CMV-22, MV-22, E-2D, MH-60R/S, MQ-4C, P-8A, and UH-1Y.

Common Mission Computing and Displays (CMCD) (OSIP 06-20) upgrades mission computers, processing capabilities, and display solutions to meet expanding data and mission requirements. CMCD leverages Commercial Off-the-Shelf technologies and open architecture systems to enable rapid capability insertions and manage obsolescence at reduced cost. The program is centrally managed to create efficiencies across platforms, with tailored configurations for each aircraft. Current efforts include re-hosting legacy software for the T-45C and integrating advanced processors for the E-2D, supporting multi-platform applications and future technology refreshes.

GPS Modernization (OSIP 04-25) funds the procurement and installation of M-Code GPS receivers, developed in coordination with the Space Force and Air Force, to enhance electronic protection and support electronic attack and support missions. The objective is to ensure all Navy GPS user equipment is M-Code capable, addressing emerging threats and complying with Public Law 111-383. Integration efforts include interim solutions for critical platforms and phased fielding as development schedules allow, with initial procurements starting for E-6B and subsequent integration for platforms such as MV-22B, F/A-18E/F, EA-18G, E-2D, P-8A, MH-60R/S, and UH-1Y/AH-1Z.

Digital Interoperability for MAGTF Agile Network Gateway Link (MANGL) (OSIP 06-25) is a Marine Corps initiative to enhance digital connectivity and interoperability across multiple generations of technology. The program integrates gateways, software-defined radios, and Commercial Off-the-Shelf interfaces to enable advanced waveforms, logistics tracking, electronic warfare/cyber capabilities, and data fusion. MANGL supports real-time situational awareness, operations in denied environments, and centralized management of end-user devices, with rapid prototyping and integration planned for MV-22, CH-53K, and KC-130J.
