Direct proof of use
Burkan-1 use in the 2014 Yemen Civil War is documented in CSIS Missile Threat reporting and its broader missile-war study. CSIS says Houthi forces first fired the new Scud-variant in September 2016 at a Saudi air base in Taif, then recorded additional Burkan-1 events including an October 2016 launch toward the Jeddah/Mecca area, a January 2017 strike on Zuqar Island, and a May 2017 missile that flew toward the Riyadh area.
CSIS Missile Threat separately reported that Houthi-Saleh forces launched an 800 km Borkan-1 from northern Yemen on July 27, 2017 and that Saudi Arabia intercepted it 69 km south of Mecca. That report noted competing target claims: the Saudi-led coalition framed the event as a Mecca-area attack, while Houthi-Saleh sources said the missile was aimed at King Fahd Air Base near Taif.

Timeline
The public Burkan-1 record begins in September 2016, when Houthi forces unveiled the missile and fired it toward King Fahd Air Base near Taif. CSIS lists an October 2016 Burkan-1 launch toward the Jeddah/Mecca area and says the missile fell north of Mecca after flying hundreds of kilometers.
In January 2017, CSIS says a Burkan-1 hit a Saudi-UAE military base on Zuqar Island in the Red Sea, an event it lists among high-casualty missile incidents. On May 19, 2017, CSIS records a Burkan-1 flight of about 825 km before it landed southwest of Riyadh. On July 27, 2017, CSIS Missile Threat reported another northern Yemen launch that Saudi air defenses intercepted south of Mecca.

Narrative
In Yemen-war service, Burkan-1 functioned as a Houthi-aligned long-range strike missile rather than a battlefield rocket used on front lines inside Yemen. Its documented targets and reported trajectories were coalition bases, island facilities, and Saudi population or military areas far beyond the immediate Yemen-Saudi border.
The missile also marked a change in the range of the Houthi missile campaign. CSIS describes Burkan-1 as a likely modified Shahab-1 with a reduced payload and about 800 km range, while Breaking Defense reported that the Houthi Ministry of Defense presented it in 2016 as a locally upgraded Scud-type missile. The Washington Institute describes Burkan-1 as the first locally upgraded Scud variant fired by the Houthis at the Jeddah-Taif-Mecca axis.
Open sources differ on some individual target claims. Saudi and coalition statements often described Mecca-area interceptions, while Houthi-aligned sources described military or airport targets near Taif or Jeddah. The direct-use record is stronger on the fact of Houthi Burkan-1 launches from Yemen than on the intended aim point of each disputed flight.
