Heavy Lift

For more than 30 years, ILC Dover has applied its Lighter-Than-Air technology to the development and fabrication of heavy lift vehicles.  We have developed durable laminates capable of providing very high tear strength while keeping structural mass to a minimum.  By utilizing the lift generated by a helium-filled LTA vehicle, heavy loads can be transported in an economical manner, and operated in areas with little existing infrastructure.

ILC developed and produced the envelope structure for the Long Endurance Multi-Intelligence Vehicle (LEMV) which was designed to provide extended ISR coverage by carrying higher mass payload sensors to high altitude for extended periods.  The LEMV is the world’s largest hybrid vehicle and is being evaluated as a heavy lift vehicle at lower operational altitudes.

ILC performed the following activities for the LEMV heavy lift vehicle program:

  • Design
  • Materials development
  • Production
  • Field support
