CH-46E and UH-1N Weapons Systems Trainers Visual Upgrades

Customer: Naval Air Warfare Center Training Systems Division (NAWCTSD)

User: U.S. Marine Corp

ASI received a contract from NAWCTSD in October 2008 (under the TSC-II Lot 1 contract vehicle) for the development, fabrication, and testing of modifications to the CH-46E and UH-1N WSTs, Devices 2F173-1, 2F173-2 and 2F161.

The multi-year upgrade effort requires the delivery of major Baseline Configuration Upgrades to the CH-46E WSTs located at the Marine Corps Air Station (MCAS) Camp Pendleton, California (CA), and MCAS Miramar, CA, as well as the UH-1N WST located at the MCAS Camp Pendleton, CA. The Baseline Configuration Upgrade requirements include visual system upgrades, Host Computer and Instructor Operator Station rehosts, and correction of operational discrepancies.  The program also includes requirements to implement Engineering Change Proposal configuration upgrades to improve trainer concurrency with fleet aircraft configurations at each site, as well as CH-46E WSTs located at MCAS New River, NC and Futenma, Japan. ASI’s efforts will upgrade each trainer to reflect the latest aircraft configuration, increase training system reliability and performance, and reduce total life cycle support costs.

ASI is also providing Program Management and Logistics Support services to support the successful completion of this program.

About the CH-46E

The mission of the CH-46E Sea Knight helicopter in a Marine Medium Helicopter (HMM) squadron is to provide all-weather, day/night, night vision goggle (NVG) assault transport of combat troops, supplies, and equipment during amphibious and subsequent operations ashore. Troop assault is the primary function and the movement of supplies and equipment is secondary. Additional tasks are: combat and assault support for evacuation operations and other maritime special operations; over-water search and rescue augmentation; support for mobile forward refueling and rearming points; aeromedical evacuation of casualties from the field to suitable medical facilities.

The CH-46 Sea Knight was first procured in 1964 to meet the medium-lift requirements of the Marine Corps in Viet Nam with a program buy of 600 aircraft. The aircraft has served the Marine Corps in all combat and peacetime environments. However, normal airframe operational and attrition rates have taken the assets to the point where a medium lift replacement is required. The safety and capability upgrades are interim measures to allow continued safe and effective operation of the Sea Knight fleet until a suitable replacement is fielded.

About the UH-1N

The UH-1N Iroquois is used by the Marine Corps to provide all-weather, day-or-night airborne command, control and coordination for assault support operations. Additionally, it is used for assault transport and maritime special operations, forward air control, aeromedical evacuation of casualties from the field and tactical recovery of aircraft and personnel missions.

The H-1 family of helicopters, popularly known as the Huey, is the most successful military helicopter ever produced — more than 16,000 have been produced since 1956. Originating from a 1955 U.S. Army contract for a medical evacuation helicopter, the first Navy/Marine Corps Iroquois variant, the UH-1E, was first procured in 1964. Deliveries of the current version, the HH/UH-1N, began in 1971. The last, and newest, UH-1N was delivered in January 1979. Both the Navy HH-1N fleet and the Marine Corps UH-1N fleet are scheduled to start being replaced by the UH-1Y in March 2008. The UH-1N could be in the fleet until 2014 when the last UH-1Y is delivered.

UH-1N Iroquois are fielded in Marine Light Attack Helicopter Squadrons, or HMLAs, along with the AH-1W Super Cobras. Detachments from the HMLAs are deployed as part of Marine Expeditionary Units to support ship-based amphibious exercises and operations.
