Note: This is a sub-section of Napier
Post WWII: Along with every other engine company in the post-war era, Napier turned to jet engine designs. Deciding to attack the only market not yet wrapped up by the larger vendors, Napier started the design of a number of turboprop designs which saw some use, notably in helicopters. Their first design, the Naiad and Double Naiad were intended for various Royal Navy Fleet Air Arm designs, but saw no use in the end.
