The AV-8B Harrier, Head Up Display (HUD) camera is an internal reconfiguration of the Litton camera, Part Number 452275-2. The new PSI Part Number is 93-4040-100 and reflects a Litton Part Number of 452275-3. NSN 7RH 5836 - 01 - 498 - 0557 - A8

Part Number 452275-2. The new PSI Part Number is 93-4040-100 and reflects a Litton Part Number of 452275-3. NSN 7RH 5836 - 01 - 498 - 0557 - A8

The internal workings of the Litton camera have been changed to incorporate current state of the art
electronics. The changes include:

      • New printed circuit board assembly

      • New lens

      • New drive motor/gear head assembly



  • The former test connector used only during the manufacturing process, has been replaced with a BNC video connector which enables the output video of the camera to be viewed on a monitor.
  • The input connector to the camera utilizes the same connector type and the same pin function as the Litton camera.
  • The body of the camera is the same size and utilizes the same mechanical mounting provisions used on the prior Litton Camera.
  • The new camera does not use the Night Vision Goggles (NVG) prism assembly previously mounted atop the Litton camera. That assembly is obsolete due to the U.S Marines utilizing a different NVG      system.
  • The camera looks into the existing Smith’s designed optical periscope to combine the outside world with the HUD symbology.
  • The optical periscope limits the resolution of the new camera system to the point where the system resolution is close to that of the existing system, even though the new camera has a significantly higher resolution than the older Litton camera.
