CH-53E and CH-46E Aircrew Procedures Trainer

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

User: U.S. Marine Corps

ASI received a contract from NAWCTSD in August 2007 (under the TSC-II Lot 1 contract vehicle) for the development, fabrication, and testing of modifications to the CH-53E and CH-46E APTs, Devices 2F171 and 2F172 located at the Marine Corps Air Station (MCAS) Futenma, Okinawa, Japan. The purpose of these modification efforts is to increase training system reliability and reduce total life cycle support costs and obsolescence issues. The intent is to reduce total ownership cost by leveraging commonality with other fielded United States Marine Corps (USMC) training devices and maximizing use of Commercial Items. The primary use of the CH-53E and CH-46E APTs is to train Marine Corps pilots in those unique skills and techniques involved with cockpit familiarization, flight characteristics, operating procedures, and mission procedures.

The development and modifications includes the replacement of the Visual System Image Generator and Projector System, a new Instructor Operator Station, and the replacement and integration of the Host Computer System. The replacement of the host includes the integration of the Marine Corps Aviation Common Computing Environment (MACCE) system. ASI is also providing improvements to the trainer to correct previous operational deficiencies and to provide new Visual System Databases.

The following CH-53E and CH-46E trainer systems were developed and/or integrated by ASI:

  • Aerodynamics
  • Tactics System
  • Control Loading
  • Aircraft systems
  • Avionics
  • Trainer I/O
  • Instructor / Operator Station
  • Out-the-Window Visual System
  • Autopilot
  • Rotor System
  • Navigation
  • Host Computer system

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

About the CH-53E

The CH-53E Super Stallion, the Marine Corps’ heavy lift helicopter, is one of the few helicopters in the world configured with 3 gas turbine engines and in-flight refueling. The CH-53E is a larger version of the CH-53 Sea Stallion, and the largest helicopter in the U.S. military inventory. It is used to transport personnel and equipment, and lift and transport heavy loads.

Designed for the transportation of material and supplies, it is compatible with most amphibious class ships and is carried routinely aboard LHA (Landing, Helicopter, Assault: an amphibious assault ship), LPH (Landing Platform, Helicopter: an amphibious assault ship) and now LHD (Landing, Helicopter, Dock: an amphibious assault ship) type ships. The helicopter is capable of lifting 16 tons (14.5 metric tons) at sea level, transporting the load 50 nautical miles (57.5 miles) and returning. A typical load would be a 16,000 pound (7264 kilogram) M198 howitzer or a 26,000 pound (11,804 kilogram) Light Armored Vehicle. The aircraft also can retrieve downed aircraft including another CH-53E. The 53E is equipped with a refueling probe and can be refueled in flight giving the helicopter indefinite range.

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.
