Welcome to Vertipedia!

What is Vertipedia?
Vertipedia is a comprehensive online reference for vertical lift aircraft. Our goal is to provide high-quality information on aircraft design and configuration, key physical and performance characteristics, and rotors and powerplants to industry, academia and the public.

Vertipedia provides data on a wide and growing range of aircraft, from historical and experimental examples to up-to-the-minute machines in front-line service. Each aircraft provides an overview that contains basic information such as manufacturer, operational status, and number of engines. This information is available to all.

Much more complete, in-depth views, however, are available to AHS members. This includes dimensional and layout data, specific performance data, powerplant information, and data on lift and control devices such as main and tail rotors. If you are not currently a member of AHS, we provide valuable benefits well beyond Vertipedia - why not join us today?

Get started!
Vertipedia's search page provides a number of ways to locate individual aircraft, as well as manufacturer and operator information.

Finding information in Vertipedia: More specific searches can be made based on VTOL type (i.e. autogyro, helicopter, jet lift, and so on), by lift configuration (i.e. single main rotor, coaxial rotor, tilt wing), or even by operational status.

Give it a try!

Help Vertipedia grow!
Vertipedia currently contains data on 403 aircraft and 233 powerplants. 215 organizations are also represented, including manufacturers, operators and design authorities.

One day, Vertipedia will be the standard reference for all makes and models of vertical lift aircraft ever flown. But we need your help to get there. If you'd like to contribute, check out how you can get involved! We are looking for volunteers across the AHS membership to help Vertipedia grow, especially in areas like research and data entry.

On May 26 in the history of vertical flight:

1965 - Light Observation Helicopter (LOH) contract awarded to Hughes OH-6A

Featured Aircraft
Our latest featured aircraft for May is the Sikorsky HH-52A Seaguard .

A derivative of the world’s first truly amphibious helicopter, the Sikorsky HH-52A entered service with the US Coast Guard in 1962, and remained in service until 1989. The first turbine-powered helicopter operated by the USCG, the HH-52 could land and take off from the water. It had a boat-shaped hull and even carried an anchor.


Credited with saving over 15,000 lives, the HH-52A was small enough to be deployed from USCG cutters, but was designed to carry a crew of three and up to ten rescuees. It carried a record 12 rescuees, along with the crew, during the Burmah Agate maritime disaster in 1979.
