The U.S. Air Force’s Stealth Drone Could Have a New Mission
Photographs point to possible maritime tasks for the RQ-170
A photographer spotted what appears to be a new variant of the U.S. Air Force’s secretive, stealthy RQ-170 Sentinel spy drone.
Matt Hartman of Shorealone Films photographed an apparently heavily-modified Sentinel while covering the launch of a top-secret satellite from Vandenberg Air Force Base in southern California on March 1, 2017.
The batwing RQ-170, which Hartman observed from below and head-on while the drone was in flight with its landing gear lowered, sported dark-colored paneling along its leading-edge and under its port wing, as well as a instrument probe — all previously-unseen features on the Sentinel.
It’s not clear what, if any, new capabilities the modified Sentinel possesses — or what new missions the Air Force might assign to the apparently-upgraded drone. It’s worth noting that the Air Force quietly began flying RQ-170s from Vandenberg as early as 2011, according to documents that journalist Joseph Trevithick obtained via the Freedom of Information Act.
The 30th Reconnaissance Squadron, the main Sentinel unit, flies from Creech Air Force Base in Nevada. Vandenberg mostly handles space launches. But the remote installation could become a major drone hub. The base previously hosted Global Hawk spy drones and the secretive X-37B robotic space plane, and is a candidate to receive a new wing of Reaper hunter-killer drones.

Vandenberg is adjacent to the U.S. Navy’s 36,000-square-mile Pacific Range ocean test site. Reporter Tyler Rogoway, editor of The War Zone blog, exclusively published Hartman’s photographs of the modified RQ-170.
Rogoway has his own theories about the drone’s modifications.
“The RQ-170, with its electo-optical sensors and what most experts think is a highly sensitive AESA-based synthetic aperture radar … could make the aircraft a potent targeting and surveillance node in an anti-access maritime and/or littoral combat environment.”
“Proving that the RQ-170’s talents can be applied to the surface warfare realm would require that the aircraft have access to such an environment,” Rogoway added, “and the middle of the Nevada desert surely does not offer that kind of an opportunity, but Vandenberg AFB certainly does.”
If Rogoway is right and the Sentinel is taking on a maritime role, it could greatly expand what is already a diverse mission portfolio. The Air Force reportedly acquired around 30 RQ-170s from Lockheed Martin in the early 2000s and deployed them for surveillance missions over Iraq in 2003.
In 2007, a photographer spotted a Sentinel at Kandahar airfield in southern Afghanistan — the radar-evading drone’s public debut. The Air Force copped to the RQ-170’s existence in 2009, the same year the flying branch deployed the pilotless aircraft to Guam and South Korea on temporary tours.
A Sentinel reportedly spied on Osama Bin Laden’s compound during the May 2011 raid by Navy SEALs that killed the terrorist leader. And in December 2011, an RQ-170 crashed on the Iran-Afghanistan border and was seized by Iranian officials for display and study.
That Sentinel’s frequent proximity to Iran and North Korea raised the possibility that the Air Force was sending the stealth drone on missions to investigate nuclear-weapons facilities.
Corroborating that theory, the Air Force implied in a document dated 2013 — which Trevithick also obtained via the Freedom of Information Act — that the RQ-170 had participated in “national collection missions,” which is military code for specialized strategic reconnaissance, often targeting nuclear installations.
From Special Operations Forces support to nuclear-snooping, in 2012 the Sentinel’s mission set expanded to include post-strike recon for B-2 stealth bombers, according to yet another document that Trevithick obtained via the federal information law.
In October 2012 at White Sands Missile Range in New Mexico, the Air Force tested a new version of the 15-ton Massive Ordnance Penetrator, a special bomb that the B-2 can drop to destroy deeply-buried strategic targets, including command bunkers and nuclear sites.
As part of the test, an RQ-170 followed behind the MOP-dropping stealth bomber in order to assess the results of the simulated strike. In a real-world raid, a B-2 could bomb a buried target and a Sentinel could perform post-attack battle-damage assessment.
The steady addition of new missions over the Sentinel’s roughly 15-year existence represents a strong vote of confidence on the part of the Air Force in the stealth drone’s usefulness, despite Iran’s capture of one of the robots in 2011.
The apparent new modifications to the RQ-170 inadvertently on display over southern California in March 2017 could point to even more missions to come.
