Airframe Modification

Advanced Systems Integration

Airframe Modification

Our team has experience with all types of airframe structural reinforcement and repair. We develop engineering plans, design structural components, and build to specification.



Strengthening key areas of the airframe to handle increased stress or to extend the aircraft’s operational life.


Modifying the aircraft’s external structure to improve aerodynamic efficiency, which can enhance speed, maneuverability, and fuel efficiency.


Replacing parts with lighter materials, such as advanced composites, to reduce overall weight and improve performance.


Modifying the airframe to increase fuel capacity for extended range or endurance.


  • Stealth Technology Integration: Adding or improving stealth features to reduce the aircraft’s visibility to radar and other detection methods.
  • Hardpoint Additions or Modifications: Adding or altering hardpoints for carrying additional or different weapons, fuel tanks, or other equipment.
  • Avionics Bay Expansion: Modifying the airframe to accommodate more advanced or additional avionics systems.
  • Cockpit Upgrades: Redesigning or updating the cockpit to integrate new control systems or improve pilot ergonomics and situational awareness.
  • Drag Reduction Improvements: Making changes to reduce drag, thereby improving speed and fuel efficiency.
  • Landing Gear Modifications: Upgrading or altering the landing gear to support increased weight, different operational environments, or improved reliability.
  • Heat Signature Reduction: Implementing design changes to reduce the aircraft’s heat signature, making it less detectable by infrared tracking.
  • Carrier Operation Adaptations: Modifying airframes for compatibility with aircraft carrier operations, including reinforced landing gear and tailhooks for arrested landings.
  • Environmental System Upgrades: Enhancing or modifying environmental control systems to improve pilot comfort and effectiveness, especially in extreme conditions.
  • Corrosion Protection: Implementing advanced materials or coatings to protect against corrosion, particularly for aircraft operating in marine environments.
  • Bird Strike Reinforcement: Strengthening key areas of the airframe, such as the windshield and leading edges, to withstand bird strikes.

Advanced Systems Integration

We can perform CAD design and modeling of your next avionics system and panel – from single instrument replacement to all new “glass.” Radar systems, ADS-B, multifunction displays and GPS units, Wifi, and HUD integration are all options here at Legionnaire Aerospace. From structural to electrical, we design, build, or modify to fit your needs.

Implementing cutting-edge navigation, communication, and targeting systems to improve the aircraft’s situational awareness, accuracy, and connectivity.


Installing advanced electronic countermeasures, including radar jamming and decoy systems, to enhance survivability in hostile environments.


Incorporating newer, more effective weapon systems and delivery methods, ensuring compatibility with a wide range of munitions.


Adding or upgrading sensors such as infrared, laser, and radar systems to provide better detection, tracking, and engagement capabilities.


  • Improved Cockpit Interfaces: Modernizing cockpit displays and controls to facilitate more intuitive and efficient pilot interactions, often incorporating touchscreens and voice command systems.
  • Software Enhancements: Updating the software that controls various systems on the jet fighter, improving processing power, user interface, and decision-support tools.
  • Network-Centric Warfare Capabilities: Enabling aircraft to operate within a network-centric environment, sharing information seamlessly with other units and command structures for coordinated operations.
  • Stealth Technology Integration: Applying advanced materials and design techniques to reduce the aircraft’s radar and infrared signatures, making it harder to detect and target.
  • Engine Upgrades: Integrating more powerful or efficient engines to improve speed, maneuverability, and fuel efficiency.
  • Autonomous or Unmanned Capabilities: Incorporating systems that allow for autonomous operation or remote piloting of the aircraft under certain conditions.
