USS Carolina do Norte (BB-55) é o navio líder dos navios de guerra da classe Carolina do Norte e o quarto navio de guerra da Marinha dos Estados Unidos a ser nomeado para o Estado da Carolina do Norte. Foi o primeiro navio de guerra americano recém-construído a entrar em serviço durante a Segunda Guerra Mundial e participou de todas as grandes ofensivas navais no Teatro de Operações do Pacífico; Suas 15 estrelas de batalha fizeram dela o navio de guerra americano mais condecorado da Segunda Guerra Mundial.

General Characteristics and Role

The Boeing X-36 Tailless Fighter Agility Research Aircraft was an experimental subscale jet developed by McDonnell Douglas (later Boeing) for NASA and the US Air Force in the mid-1990s. Its primary role was to test the feasibility of a fighter aircraft design that lacked the traditional vertical and horizontal tail surfaces. The X-36 was intended to explore how a tailless configuration could enhance stealth (by reducing radar cross-section) and improve maneuverability, particularly at high angles of attack, compared to conventional fighter jets. It was flown remotely by a pilot in a ground station due to its small size and lack of a cockpit.

Powerplant and Flight Controls

  • Engine: 1 x Williams International F112 turbofan engine.
  • Thrust: Approx. 3.1 kN (700 lbf).
  • Top Speed: Estimated at 370 km/h (230 mph).
  • Flight Control System: Required a highly advanced Digital Fly-By-Wire (DFBW) system to maintain stability, as the aircraft was inherently unstable without tail surfaces.
  • Control Surfaces: Yaw and pitch control were achieved using canards (foreplanes) and a combination of split ailerons (flaperons) and a **thrust-vectoring nozzle** on the engine.

Program Outcome and Legacy

  • Test Program: The X-36 completed a highly successful test program, demonstrating excellent maneuverability with its tailless design. It achieved a total of 31 flights, logging 15 hours of air time.
  • Success Metric: The program demonstrated that a tailless fighter design could achieve up to a 40% increase in cruising lift and a significant improvement in agility over conventional designs.
  • Influence: Although the X-36 never led directly to a production aircraft, its successful demonstration of control and stability heavily influenced subsequent low-observable (stealth) aircraft design and DFBW control systems, including possible future unmanned combat air vehicles (UCAVs).
  • Preservation: Both X-36 prototypes are now preserved: one is at the National Museum of the United States Air Force in Ohio, and the other is at the NASA Dryden Flight Research Center (now Armstrong) in California.
