Sikorsky and Boeing have provided the first look at the SB>1 Defiant helicopter the companies have developed for the US Army's Joint Multi-Role technology demonstrator program. It is designed to fly at twice the speed and range of today's conventional helicopters and offers advanced agility and manoeuvrability. It will help inform the next generation of military helicopters as part of the US Army's Future Vertical Lift program.
The helicopter is participating in the Army's Joint Multi-Role-Medium Technology Demonstrator programme. Data from it will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s.
