Relentless

Aircraft Exterior

The Bell 525 Relentless incorporates an advanced aerodynamic design, a Next Generation GE® engine and a rugged airframe, delivering best-in-class payload-range capability to meet our customer’s mission requirements.

Rugged Airframe Construction

The Bell 525 Relentless airframe delivers rugged dependability through an optimized usage of metal and composite structures:

  • Optimized usage of metals and composites keep the max gross weight of the aircraft under
    20,000 lbs.
  • ARC Horizon® flight deck provides health monitoring and flight
    plan optimization.
  • Optimized center of gravity provides indiscriminate loading capability.
  • Designed with MSG-3
    maintenance standards.
  • Live-mount rotor system reduces aircraft vibration and associated wear and tear.
