According to some sources, the evasive MH-X may have taken part in the raid that killed Islamic State member Abu Sayyaf.

In the night between May 15 and 16, U.S. Special Operations forces killed ISIS high level operative Abu Sayyaf, in a daring raid that took place in eastern Syria.

Little is known about the raid.

According to the CNN, the operation was conducted by U.S. Army’s Delta Force, which was carried to a residential building in Deir Ezzor, to the southeasth of Raqqa, by Army Blackhawk helicopters and Air Force CV-22 Osprey tilt-rotor aircraft.

It’s pretty obvious many other assets were actually involved in the raid, including support assets providing electronic support to the intruding choppers and drones, as happened during Operation Neptune’s Spear, for the killing of Osama Bin Laden.

The presence of some Air Force Special Operations Command Ospreys during a raid against ISIS is not a first.

U.S. Osprey tilt-rotor aircraft probably based in Kuwait have already conducted missions in Syria and Iraq: on Jul. 3, 2014, some V-22 aircraft were used to carry Delta Force commandos to a campsite in eastern Syria where ISIS militants were believed to hold American and other hostages (that had been moved by the time the commandos attacked the site).

On Aug. 13, 2014, V-22s deployed military advisers, Marines and Special Forces on Mount Sinjar to coordinate the evacuation of Yazidi refugees.

What could really be a “first” is the possible involvement of the Stealth Black Hawk helicopter exposed by the raid in Abbottabad, Pakistan, back in 2011.

For the moment it’s just a hypothesis, but Homeland Security suggests that the Delta Force team were transported deep into ISIS-held territory “via presumably stealth equipped Black Hawk helicopters” of the 160th Special Operations Aviation Regiment (Airborne) “Night Stalkers”.

The U.S. Army special ops force provides support for both general purpose and special operations forces. They fly MH-47G Chinooks, MH-60L/K/DAP Black Hawks, A/MH-6M Little Birds, MH-X Silent Hawks (the latter is an unconfirmed designation for the Stealth Black Hawk), maybe stealthy Little Birds and stealthy Chinooks, as well as MQ-1C Gray Eagle drones.

160th SOAR’s Black Hawk helicopters presence in the region was first unveiled after an unspecified variant belonging to the U.S. Army took part in an unsuccessful raid to free captured American journalist James Foley and other captives from ISIS in eastern Syria in August 2014.

Even though American aircraft have already demonstrated their ability to operate completely undisturbed well inside the Syrian airspace, we can’t rule out the possibility that the Pentagon, as done in 2011 when the time to kill Bin Laden arrived, considered the importance of the most recent raid against the senior ISIS leader and the failure of at least a couple previous raids, decided to commit the most advanced and secret Black Hawk helicopter to the delicate mission against Abu Sayyaf: the stealth variant.
