Source-derived summary

The Boeing Phantom Ray is an American demonstration stealth unmanned combat air vehicle (UCAV) developed by Boeing. The autonomous Phantom Ray is a flying wing around the size of a conventional fighter jet, and first flew in April 2011. It will conduct a program of test flights involving surveillance, ground attack and autonomous aerial refueling missions. The developers say it can carry 4,500 pounds (2,040 kg) of payload.

Design and development

The Phantom Ray project, internally referred to as "Project Reblue" at Boeing, was initially conceived in mid-2007 and officially commenced in June 2008. The project was secret within the company, except for a small number of executives and engineers, until May 2009.

Developed by the Boeing Phantom Works, the Phantom Ray is based on the X-45C prototype aircraft, which Boeing originally developed for the Defense Advanced Research Projects Agency (DARPA), the US Air Force, and the US Navy Joint Unmanned Combat Air Systems (J-UCAS) program in 2002. The Phantom Ray was not aimed at any particular military program or competition, although Boeing considered using the design as an entry for the Navy's Unmanned Carrier-Launched Surveillance and Strike (UCLASS) program.

The Phantom Ray was unveiled on May 10, 2010, in St. Louis, Missouri.

Editorial analysis

Why this record matters

“Boeing Phantom Ray” is worth following because a concise public description often conceals a longer documentary argument. Here, Boeing, Phantom and unmanned provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 8, 2025. The linked authority identifier is Q721716. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011, 2007, 2008 and 2009.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
