Cruises 50% faster, flies 50% farther, has a 30% larger cabin, and can lift 5,000 more pounds than the legacy platform, while introducing full autopilot capability to reduce pilot workload
State-of-the-art avionics system with advanced flight deck functionality and improved situational awareness resulting in reduced crew workload
Right-sized aircraft for maximum operational efficiency and lower operating & support costs
An off-the-shelf, readily available solution that leverages repurposed technologies from proven Boeing Rotorcraft programs to guarantee performance, flexibility & safety

Unique Capabilities

Cockpit

The cockpit was designed to increase safety while providing excellent visibility and a reduced pilot workload. The avionics suite features an open architecture that facilitates future growth.

Slide down tactical windows

Facilitate use of pintle mounted machine guns that do not obstruct the side cabin doors.

Cabin

Spacious, unobstructed, constant cross section cabin with a square floor plan that is fully accessible and usable, and offers maximum mission flexibility and seating for up to 15 people. Both sides of the cabin can be accessed through the large sliding cabin doors with high clearance from main and tail rotors.

Reduced IR Signature Engine

Engines are mounted in separate engine turbine burst containment compartments and have independent inputs to the main gearbox. Side facing engine air intakes greatly reduce bird strike or flying object ingestion. IR Signature is lowered with airflow and a directional exhaust which also reduces plume impingement on the tail fuselage.

Rotor System & Drive Train

Main Rotor System Design - The main rotor is a five blade, completely articulated fail-safe system designed for improved performance, reliability, and lower noise. High main and tail rotor ground clearance ensures a safe environment for ground personnel.

The Sustainable, Affordable Solution

MH-139A's lower operating costs, increased reliability & improved maintainability translate into more than $1B in savings for the Air Force across the aircraft’s life cycle. Boeing’s MH-139A meets or exceeds all U.S. Air Force requirements at the most affordable price by reducing the cost and manpower required to operate and maintain the aircraft.

Designed for maintainability utilizing advantages of condition-based maintenance, MH-139A delivers higher availability, better maintainability and assured mission reliability. This is accomplished through:
