Direct proof of use
R-17 Scud-B use in the 2014 Yemen Civil War is documented first through the Houthi-aligned seizure of Yemen's pre-war missile forces. Michael Knights, writing for the Combating Terrorism Center, reported that as the Houthi movement seized power in Sanaa it inherited R-17E Elbrus missiles, identified by NATO as SS-1C Scud-B short-range ballistic missiles, along with operational launchers.
The launch record is less precise than the stock record because many 2015 reports used the broad term Scud. CSIS reports that Houthi forces fired a ballistic missile at Khamis Mushait on June 6, 2015, shortly after coalition officials had claimed the Houthi missile capability was destroyed. The Washington Institute later summarized the early arsenal as including four surviving prewar R-17 Scud-B or Hwasong-6 missiles fired into Saudi Arabia, while Oryx lists R-17 Elbrus Scud-B missiles as inherited from pre-war Yemeni Army stocks, mostly converted to Burkan missiles, and depleted.

Timeline
The sequence begins with state capture rather than a new import. During the September 2014 takeover of Sanaa and the subsequent alignment with Saleh-linked military units, Houthi-aligned forces gained access to strategic missile forces and inherited R-17E/Scud-B stocks.
The Saudi-led coalition's opening air campaign in March and April 2015 targeted Houthi missile capabilities and was publicly described by coalition officials as having destroyed them. CSIS notes that Yemeni army sources still estimated 60 to 70 ballistic missiles remained, and that the June 6, 2015 Khamis Mushait launch showed the Houthis retained ballistic-missile capability.
By 2016 and 2017, the older Scud-family stock was being replaced or transformed. Washington Institute reporting describes the initial R-17 Scud-B or Hwasong-6 missiles as part of an early arsenal expended by 2017, and Oryx lists R-17 Scud-B stocks as depleted after most were converted to Burkan missiles.

Narrative
In Yemen-war service, the R-17 Scud-B belonged to the Houthi-aligned long-range strike layer rather than to front-line ground combat. Its role was to threaten Saudi bases and rear-area targets after the Saudi-led coalition intervened in March 2015, especially before later Houthi missile types such as Qaher and Burkan became prominent.
The strongest sources distinguish possession, fielding, and use. CTC directly identifies inherited R-17E/Scud-B missiles after the takeover of Sanaa. CSIS documents the early Houthi Scud/ballistic-missile campaign, including the June 2015 Khamis Mushait launch and the coalition's incomplete destruction of missile stocks. The Washington Institute gives the most specific use summary for the R-17 category, saying four surviving prewar R-17 Scud-B or Hwasong-6 missiles were fired into Saudi Arabia.
Later missile events should not automatically be assigned to an unmodified R-17 Scud-B. Oryx and CSIS both describe the transition from inherited Scud-family stocks toward Burkan missiles, while UN and specialist reporting on 2016-2017 incidents often identifies Scud-C/Hwasong-6-type or Burkan systems instead of Scud-B. This page therefore treats the R-17 Scud-B as an inherited and early-used stock, with later Scud-derived launches covered under the more specific Hwasong-6 and Burkan records when sources support that identification.
