List of rotorcraft manufacturers by country

Rotorcraft manufacturers fall into two categories:
 * 1) those that can design, certify and manufacture new designs from scratch and
 * 2) those that can only manufacture extant designs under license.

Boeing Vertol is an example of the first type and Kawasaki Heavy Industries, who license-produced Boeing Vertol designs for much of its recent history, is an example of the second.
