Proposed helicopter

XHCH General information Type Aerial crane helicopter National origin United States Manufacturer McDonnell Aircraft Status Cancelled; mockup phase only Primary user United States Navy

The **McDonnell XHCH** (**Model 86**) was a 1950s [aerial crane](/source/Aerial_crane) helicopter proposal for the United States Navy by the McDonnell Corporation.

## Development

The XHCH was developed in the early 1950s to meet a US Navy requirement for a helicopter capable of carrying supplies and ammunition between ships and carrying heavy loads for short distances from ship-to-shore or from marshalling areas ashore to front-line units. Three prototypes (BuNos 138654/138656) were ordered, and a full-size mockup was inspected in May 1953. However, budget cuts forced the Navy to cancel the XHCH-1 project on January 18, 1959, without a prototype being built.[1]
