Recognition (WEFT)
| W — Wings | High-mounted, rotary |
|---|---|
| E — Engines | 2 × piston, fuselage-mounted |
| F — Fuselage | Pod-and-boom fuselage with engines in side pods |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Pod-and-boom fuselage with engines in side pods
- Long tailwheel-style landing gear that straddles cargo
- Crew cabin in the nose with an open area for interchangeable pods
It had no fixed cabin, only a cockpit and an open area, and could sling up to 12,000 lb (5,400 kg) of cargo beneath the boom.

History
Sikorsky began designing it in 1958, using the transmission, rotor system and piston engines of the CH-37/S-56. It first flew on 25 March 1959.
Variants
Only one was built. Its development led to the larger turboshaft-powered Sikorsky S-64, which became the CH-54 Tarhe.
Where you'll see it
The helicopter made 333 flight hours in two years and was evaluated by the US Navy and demonstrated to the US Army. It proved underpowered and crashed in April 1961.
