SEA CH-46 Special Mission Modification

SEA performed as a subcontractor to Dyncorp to support the DoS INL Air Wing CH-46 Aviation Services contract. SEA provided engineering design, A-Kit development and manufacturing, and touch labor for installation of modification A-Kits and B-Kits of the Missile Warning System and Countermeasures Dispenser System for 17 CH-46 helicopters. The Missile Warning/Countermeasures System is manufactured here locally by Extant Aerospace! SEA also manufactured and provided A-Kits and touch labor for the installation of the FlightCell DZM2 Satellite Tracking and Communications System on two CH-46 aircraft. Work was performed in Hangar 17 at our facilities in Melbourne, FL. As usual, schedule was a major concern as DoS had to meet a scheduled airlift. Once again, the dedicated team at SEA met that schedule!


A Brief History of the Boeing CH-46 Sea Knight

The Boeing Vertol CH-46 Sea Knight is a medium utility helicopter, developed for the Marines and Navy, and its primary function was to support assault forces. The CH-46 has two tandem rotors and engines, and the engines are coupled, so in case of emergency the Sea Knight can fly with only one engine operational. The Sea Knight, affectionately known as the “Phrog”, was used for a variety of military task, including assault transport, carried supplies and equipment, combat support, search and rescue, forward refueling, and medical evacuation. This aircraft can accommodate up to 17 people in its cargo compartment and can carry various loads, including up to 4x 500 kg loads underslung externally. This workhorse cargo helicopter was retired from the Navy in 2004, and from the Marines in 2015, after 50 years of service.
