The unit behind CONSTANT PEG
The 4477th TES Red Eagles
The 4477th Test & Evaluation Squadron was unlike any other USAF unit. Its pilots flew Soviet-designed fighters, its maintainers kept them alive without a normal supply chain, and its mission remained hidden from almost everyone outside the programme.
A flight created in the shadows
The 4477th Test & Evaluation Flight was activated on 1 April 1977 and assigned to the 57th Fighter Weapons Wing. Its small initial cadre built operating procedures, training material and security practices while continuing conventional duties that helped mask the real mission.

Sixty-nine pilots, one demanding standard
The pilots later received numbered “Bandit” identities. Selection demanded exceptional flying skill, sound judgement and the ability to learn aircraft whose handling and systems differed sharply from American types. Every sortie balanced training value against scarce aircraft life and real risk.
“…what it will be like to employ your airplane against the best pilot that there can be in this airplane.”
Lt Col James D. ‘Thug’ Matheny, USAF (Ret.) · Bandit 27

Maintaining the impossible
The Red Eagles’ maintenance story was as remarkable as the flying. Teams reverse-engineered procedures, fabricated or recovered parts, and made serviceable aircraft from an uncertain collection of airframes. Their ingenuity kept three very different MiG types available for training.
A legacy measured in survival
The squadron gave operational crews an experience no simulator or briefing could reproduce: seeing and fighting the real aircraft. The knowledge carried into tactics, weapons employment and combat, while the unit itself disappeared back into secrecy when the programme ended in 1988.
