Officially Licensed USMC CH-46 Phrog Commemorative Patch Honoring the workhorse that carried the Corps for over half a century. The Boeing CH-46 Sea Knight — affectionately known as the "Phrog" by the Marines who flew and maintained it — served as the backbone of Marine Corps medium-lift helicopter operations from 1964 until its retirement in 2015. The CH-46 carried Marines into combat from Vietnam through Operations Desert Storm, Iraqi Freedom, and Enduring Freedom, logging millions of flight hours in every environment imaginable. From ship-to-shore assault to casualty evacuation, resupply, and humanitarian relief, the Phrog did it all with a reliability and ruggedness that earned it a permanent place in Marine aviation history. This officially licensed commemorative patch celebrates the aircraft and the community that kept it flying. Perfect For: CH-46 aircrew and maintainers, Marine medium helicopter squadron veterans, Phrog community members, and collectors preserving the legacy of Marine rotary-wing aviation. Once a Phrog, always a Phrog.
