The X-47B unmanned combat aircraft (UCAV) was a revolutionary development for the United States Navy, offering a new level of autonomous capability and stealth technology. Its creation was a result of a contract awarded to two aerospace companies, Northrop Grumman and Boeing, in 2007 to develop prototypes of UCAVs. Northrop Grumman was responsible for designing and developing the X-47B, which was intended to be an unmanned aircraft that could operate autonomously or be remotely piloted.

The X-47B was specifically designed for use by the US Navy, and it was the first UCAV to be developed for this purpose. It was also uniquely designed to operate from aircraft carriers. The development costs of the X-47B were significant, with the program costing almost $1.5 billion by 2015, and the costs have continued to rise, reaching nearly $2 billion in 2023.

Despite the high costs, the X-47B program met the evolving Navy requirements, and the aircraft was a significant technological advancement. The aircraft had a maximum takeoff weight of 44,567 pounds (20,215 kg) and a range of 2,400 miles (3,900 km, 2,100 nmi). It was powered by a single Pratt & Whitney F100-220U turbofan engine, which gave it a speed of over 600 miles per hour (970 km/h).

One of the most significant features of the X-47B was its stealth technology. The aircraft was designed to be a tailless, stealthy aircraft that could avoid detection by radar. It was equipped with electro-optics (EO), infrared (IR), synthetic aperture radar (SAR), inverse SAR, ground moving target indicator (GMTI), electronic support measures (ESM), and maritime moving target indicator (MMTI) sensors. These features made the X-47B difficult to detect and capable of conducting covert operations.

The X-47B also had two internal weapons bays capable of carrying up to 4,500 pounds (2,041 kg) of ordnance, including Joint Direct Attack Munitions (JDAM) and Small Diameter Bombs (SDB). This allowed the aircraft to engage targets from a distance and provide support to ground forces.

The X-47B was a significant technological advancement in unmanned combat aircraft, offering a new level of autonomous capability and stealth technology. Although the development costs were high, the program met the evolving Navy requirements, and the aircraft demonstrated its reliability and capabilities. The legacy of the X-47B will continue to shape the future of unmanned combat aircraft for years to come.
