How much does a Sikorsky helicopter weigh?

Sikorsky are a manufacturer of helicopters. In much the same way that Ford are a manufacturer of cars.

As a manufacturer of helicopters they make more than one type, so your question needs to be a little more specific.

Even if you name a specific model, there will be different roll-fits which will each have a different weight. The Sikorsky CH-53E has a maximum design gross weight of 46,500 lbs. Its maximum design gross weight with an external load is 73,500 lbs.
