We wanted to make a difference. Leave a mark. Be proud of something.
So in 1978, we joined forces with the U.S. military to produce the HGU-4/P Aviator for fighter pilots. Each Aviator is still built to the strict guidelines of MIL-S-25948J standards, a 20-page document detailing the most demanding, complex manufacturing specs around. The HGU4/P was officially recommended by army optometrists in November, 1958.
The HGU4/P Aviator sunglass design was adopted because it worked better with newer helmet designs, which had undergone major developments in the 1950s. Flight helmets were now being made with plastics, and equipped with communication equipment and oxygen masks. These helmets required a sleeker sunglasses design that could fit under the new wind blast visors with the additional equipment.
The HGU4/P is still the standard aviator sunglass specification that Randolph Engineering is under contract to produce for the U.S. Military. Randolph recently renewed their contract with the U.S. military to continue producing the HGU4/P for another five years.
