Future Long Range Assault Aircraft

SB>1 DEFIANT™

Demonstrating transformational Vertical Lift capabilities to define the FLRAA program

Overview

The U.S. Army needs a faster, more survivable, longer range helicopter that meets its performance, cost, and schedule objectives while providing unmatched operational effectiveness on the highly contested battlefield of the future.

The SB>1 DEFIANT™ is uniquely suited to achieve those objectives. Its revolutionary compound design leverages game-changing technologies to offer an integrated solution with increased speed, range, maneuverability and survivability to extend the warfighter’s capabilities on the modern battlefield – all while fitting in the same footprint as its Black Hawk predecessor.

Through innovative design and development activities over the course of the Joint Multi-Role Technology Demonstration (JMR-TD) program, the SB>1 team has refined its understanding of the X2 Technology™ that can be leveraged to fill the capability needs of the Army’s Future Long Range Assault Aircraft (FLRAA). With the data gained from the wind tunnel, Power System Test Bed (PSTB) and test flights, this team is ready to take the next steps in designing an affordable, survivable and sustainable FLRAA solution.

A Helicopter Designed for the Army’s Air Assault Mission

The Sikorsky-Boeing team’s expertise in advanced manufacturing and testing, paired with its experience in producing cutting-edge rotorcraft configurations, has refined our understanding of the Army’s mission – enabling us to provide a flexible, agile, advanced solution with adaptable software and systems for future growth across multiple missions.

To replace the Black Hawk, the Army’s next-generation helicopter must conduct air assaults from extremely long distances and evade enemy anti-aircraft systems. It is crucial that the aircraft can fly at the lowest possible altitude with a precise combination of speed and maneuverability. The aircraft needs to land quickly in tight landing zones under fire, deliver soldiers, and immediately depart.

The SB>1 DEFIANT™ is specifically designed to demonstrate technology for the FLRAA mission. The helicopter’s superior handling qualities and speed allow it to safely get to the objective, perform the complex mission and depart quickly. The SB>1 team chose this configuration featuring coaxial rotors and a rear-mounted pusher propulsor for a specific reason – to achieve the common goal that they have with the U.S. Army to design the absolute best next-generation air assault aircraft.

Revolutionary Capabilities

The SB>1 DEFIANT™ integrates the world’s most modern, proven technologies to deliver a cutting-edge aircraft to meet the Army’s FLRAA requirements. DEFIANT™ - which maintains the Black Hawk footprint - will fly twice as fast and twice as far while increasing the overall maneuverability and agility required for specific mission objectives.

  • Improved Handling
  • Enhanced Survivability
  • Reduced Vulnerablility
  • Military Utility
  • Superior Sustainability
  • Improved Handling

    With a coaxial rigid rotor system and rear pusher propulsor, DEFIANT™ delivers revolutionary thrust and speed while simultaneously enabling rapid ingress / egress for unrivaled maneuverability and agility.

  • Enhanced Survivability

    During the air assault mission, the aircraft's revolutionary design enables higher cruise speeds at lower altitudes – where the majority of the FLRAA mission is performed to avoid integrated air defense systems. DEFIANT’s™ superior handling qualities enable a more rapid landing zone entry and exit to minimize exposure to potential threats.

  • Reduced Vulnerablility

    The aircraft is able to withstand significant combat damage. If the propulsor is disabled, the aircraft can still fly at traditional helicopter speeds.

  • Military Utility

    The SB>1 DEFIANT™ is able to fly, maneuver, land and survive in tight formations – offering maximum combat effectiveness to accomplish air assault missions during multi-domain operations.

  • Superior Sustainability

    Approximately the same size as a Black Hawk, DEFIANT™ maintains commonality with the Army’s existing facilities, logistics footprint, engine and training standards. This aircraft will be able to operate for extended maintenance-free periods in austere field environments.

An Affordable, Sustainable Solution

The SB>1 DEFIANT™ team has demonstrated revolutionary advances in engineering and manufacturing, making their FLRAA offering an affordable reality today. The team’s design and development activities have refined their understanding of the technological solutions possible for the Army.

With the data gained from the wind tunnel, power system test bed (PSTB) and test flights, the Sikorsky-Boeing team is well on their way to delivering an aircraft that meets the Army’s needs. This is accomplished by:

  • Integrating modern, proven technologies into our design to ensure a low-risk, low-cost offer that is scalable to a variety of military missions.
  • Model-based engineering and advanced manufacturing that enhance our ability to minimize risk and program costs.
  • A rigorous flight test plan.
  • A design that maintains commonality with:
    • Army’s existing facilities – It is the same size as Black Hawk / Apache.
    • Current Army logistics and soldier skill sets (training).
    • Army’s major tactics, techniques and procedures to include multi-ship operations.
  • A maintenance-friendly design throughout, increasing availability and lowering lifecycle sustainment costs.
  • An early and continuous focus on reliability and maintainability to create maintenance-free periods and reduce forward logistics burdens, while establishing an affordable life cycle of sustainment.
