Another application of the F-16C/D EDU was to the South Korean T-50 ‘Golden Eagle’ a multirole trainer, developed with Lockheed Martin, giving a more than competent lead-in to the F-16 and ‘5th’ generation fighters. In the T-50 the EDU is driven by an Integrated Mission/Display Computer (IMDC) which also drives the Moving Map and Front and Rear Cockpit Displays. The EDU has an Up-Front Control Panel with an LED matrix data entry capability. This unit is marked 'Not for Flight'.

Korea Aerospace Industries Ltd. (commonly referred to as KAI, Korean: is a South Korean aerospace company; the headquarters and its major plants are located at Sacheon city.

The KAI T-50 Golden Eagle is a family of South Korean supersonic advanced trainers and light combat aircraft, developed by Korea Aerospace Industries (KAI) with the American aerospace company Lockheed Martin. The T-50 is South Korea's first indigenous supersonic aircraft and one of the world's few supersonic trainers. Development began in the late 1990s, and its maiden flight occurred in 2002. The aircraft entered active service with the Republic of Korea Air Force (ROKAF) in 2005.

The T-50 has been further developed into aerobatic and combat variants, namely T-50B, TA-50, and FA-50. The F-50 single-seat multirole fighter variant was considered. The T-50B serves with the South Korean air force's aerobatics team. The TA-50 light attack variant has been ordered by Indonesia. The Philippines ordered 12 units of the FA-50 variant. The T-50 is also being marketed as a candidate for the United States Air Force's next-generation T-X trainer programme. Thailand ordered 4 units of the T-50 advanced trainer variant.

BAE Systems Platform Solutions supplies Flight Control computers, Head Up Display, Control Stick assemblies, Rate Sensor assemblies, Accelerometer sensor assemblies, and Test Equipment. The contracts also provide for in-country production support and training in the Republic of Korea.

In the mid-90s the Company developed a variant of the F-16C/D HUD called the Enhanced Display Unit. It was intended primarily to reduce the cost of the F-16C/D Pilot’s Display Unit both in material and maintenance.

The PDU chassis was re-jigged such that two Deflection circuit modules fitted onto the outside walls and the Video Card lay flat inside., The Combiner was changed to have a dielectric coating (Vanadium Oxide) to improve the luminance and the CRT phosphor was also changed to P53 to allow it to be driven harder.

The interface remained the same so that the EDU could ‘plug and play’ with the legacy Electronics Unit or the parallel development of an Advanced Electronics Unit (AEU) or indeed Display Drivers from other suppliers, for example the multi-role GAC or Mission Computer from Raytheon. The AEU had the same form factor as the legacy F-16 C/D Electronics Unit but reduced the card count from twenty-one to just three which were mounted fore and aft rather than across the box.


As part of the F-16 Mid Life Update package it was decided to fit the Texas Instruments Modular Mission Computer (MMC) The MMC takes up 42% less volume in the aircraft, weights 55% less and consumes 37% less electrical power. Subcontractors are Terma, Nea Lindberg and Signaal. This computer consists of line-replaceable modules (LRMs) based upon several MIPSCO R3000 32-bit RISC microprocessors which run the ADA high-order language. It replaces three components, namely the computers currently in use for the Expanded Fire Control Computer (XFCC), the Head Up Display Electronics Unit (HUD EU or HUD symbol generator), and the Stores Management System's Expanded Central Interface Unit (XCIU). By 2014 1758 of these units had been fitted largely replacing the Company EU.

The EDU was  was fitted to some Block 60 F-16 E and F models. The Block 60 ‘Desert Falcon’ has been described as a lower-budget alternative to the F-35A Joint Strike Fighter and some sources claim it is a much better system than the Block 50/52 aircraft.
