A test to prove an autonomous unmanned aerial vehicle (UAV) can be refueled in flight could happen by the end of this month, officials with Naval Air Systems Command told USNI News on Monday.
The test would pair a Northrop Grumman X-47B Unmanned Combat Air System demonstrator (UCAS-D) with a contracted tanker to prove out software that could allow future unmanned aerial vehicles (UAV) to be autonomously aerially refueled (AAR) in the same way the Navy’s current crop of carrier aircraft can take on fuel from tanker aircraft.
The effort is part of a June $64 million testing contract with Northrop that was set to expire in March.
A NAVAIR spokeswoman told USNI News the “team was managing the contract to allow for AAR flights by the end of the month.”
One of the two X-47Bs — Salty Dog 502 — is plumbed to take on fuel by a so-called probe-and-drouge aerial refueling system in which a fuel line is feed out behind the tanker and meets a probe on the receiving aircraft.
USNI News understands that — with modifications — Salty Dog 502 can receive fuel from the Air Force flying boom refueling method as well.
NAVAIR will use a contracted Omega Aerial Refueling Services tanker for the test, Military.com reported last week.
On Thursday, NAVAIR conducted a successful non-contact test flight between a tanker and a X-47B.
The AAR software has been tested successfully on surrogate aircraft before the current round of testing.
