Tthe 노스롭 그루먼 X-47B 항공 모함 기반 운영을 위해 설계된 시범 무인 전투 항공 차량 (UCAV)입니다. 미국 방위 기술 회사 노스롭 그루먼이 개발한 X-47 프로젝트는 DARPA의 J-UCAS 프로그램의 일환으로 시작되었으며, 이후 미 해군의 UCAS-D(Unmanned Combat Air System Demonstration) 프로그램의 일부가 되었다. X-47B는 반자율 작동 및 공중 급유가 가능한 테일리스 제트 동력 혼합 날개 바디 항공기입니다.

General Characteristics and Role
The Northrop Grumman X-47B was an experimental, tailless, stealth-optimized jet aircraft developed under the U.S. Navy’s Unmanned Combat Air System Demonstration (UCAS-D) program. Its primary role was to demonstrate the feasibility of operating an autonomous, high-endurance, fixed-wing aircraft from an aircraft carrier. The X-47B pioneered several critical naval aviation technologies, including autonomous catapult launch, arrested recovery, and autonomous aerial refueling, proving that uncrewed, large-scale systems could fully integrate into carrier operations. Its design is characterized by its distinct “flying wing” shape, which minimizes radar visibility.

Powerplant and Carrier Capabilities
- Engine: 1 x Pratt & Whitney F100-PW-220U turbofan engine.
- Key Carrier Milestones: In July 2013, the X-47B completed the world’s first autonomous arrested landing on the deck of an aircraft carrier (USS George H.W. Bush). It later demonstrated autonomous catapult launch and in 2015, completed the first autonomous aerial refueling with a KC-707 tanker.
- Stealth Features: The tailless configuration and the placement of the engine inlet atop the fuselage contribute to its very low observable (VLO) stealth characteristics.
- Endurance: The platform was designed for very long endurance, potentially allowing for orbit times far exceeding those of crewed fighters.
- Weapons Bay: The airframe included two internal weapons bays, capable of carrying approximately 2,000 kg (4,500 lb) of ordnance.
Program Outcome and Legacy
- Success: The UCAS-D program was highly successful, validating every key technology required for a large, unmanned, stealthy platform to operate seamlessly within a carrier air wing.
- Retirement: The program concluded in 2015, as its goal was technology demonstration, not production. The Navy opted to use the lessons learned to pursue the Carrier-Based Air Refueling System (CBARS) program, which evolved into the MQ-25 Stingray.
- Influence: The X-47B’s autonomous capabilities and aerodynamic design are considered foundational for the development of the next generation of U.S. Navy and Air Force unmanned platforms.
- Preservation: The two X-47B airframes are now preserved: one is at Naval Air Station Patuxent River, Maryland, and the other is at the Intrepid Sea, Air & Space Museum in New York City.
