Sikorsky Aircraft, a subsidiary of Lockheed Martin, is awarded a task order, worth around $15 million, by the Naval Air Systems Command (NAVAIR) to support VH-3D/VH-60N executive helicopters operated by the U.S. Marine Corps (USMC).
The task order provides for security, project engineering, integrated logistics support, material support, sustainment engineering, training and program support for the VH-3D/VH-60N executive helicopter special progressive aircraft rework.
Work will be performed in Stratford, Connecticut (88%); and Quantico, Virginia (12%), and is expected to be completed in November 2020.
VH-3D Sea King
VH-3D is a twin-engine, all-weather executive transport helicopter flown by USMC’s Marine Helicopter Squadron One (HMX-1).
The first version of this workhorse helicopter was flown more than 40 years ago and was derived from the Sikorsky S-61 series. Originally developed as an antisubmarine sensor carrier for the U.S. Navy, the Sea King has been replaced in that role by the SH-60F Sea Hawk helicopter as the anti-submarine warfare (ASW) helicopter.
VH-3D includes Day/night/all-weather operations, self-contained navigation system, GPS, TCAS, survivability systems, and crash-survivable flight information recorder sensor, and carries no weapons. Communications include extensive secure and non-secure communication systems; and EMP hardening.
The VH-3D was delivered to HMX-1 in December 1974 as a replacement for the VH-3A, which entered service in 1963. By the end of 1976, the VH-3A had been completely replaced by the VH-3D. Today the 41-year-old VH-3D Sea King is being replaced by the new VH-92A Presidential Helicopter.
VH-60N White Hawk
The VH-60N is a twin-engine, all-weather executive transport helicopter derived from both the U.S. Army’s UH-60 Black Hawk and the U.S. Navy’s SH-60 Seahawk aircraft.
It is flown by USMC Marine Helicopter Squadron One (HMX-1) and supports the executive transport mission for the President of the United States.
The H-60 family of helicopters is widely used throughout the Department of Defense for anti-submarine warfare, search and rescue, drug interdiction, anti-ship warfare, cargo lift, and special operations.
The VH-60N was first delivered to HMX-1 in 1989 as a replacement for the VH-1N.
