The clearest public Yemen-specific evidence for the PKM/PK family is interdicted supply rather than a confirmed battlefield firing incident. U.S. Navy reporting on a March 2016 series of Arabian Sea seizures states that HMAS Darwin intercepted a dhow on 27 February 2016 and confiscated nearly 2,000 AK-47 rifles, 100 rocket-propelled-grenade launchers, 49 PKM general-purpose machine guns, 39 PKM spare barrels, and 20 60 mm mortar tubes. The same U.S. Navy release assessed the broader series of seizures as Iranian-origin arms likely bound for Houthi insurgents in Yemen.
Conflict Armament Research separately examined verified photographs from the HMAS Darwin seizure and described a Russian-manufactured PKM-pattern general-purpose machine gun among the documented materiel. CAR also recorded the important destination caveat: coordinates in the dhow's GPS system indicated Caluula, Somalia, while U.S. and partner reporting treated the regional dhow traffic as part of a Somalia-Yemen trafficking picture.
Later U.S. Navy reporting shows the same weapon family recurring in the interdiction record. In May 2021, USS Monterey seized hundreds of PKM machine guns from a stateless dhow in the North Arabian Sea; in December 2021, NAVCENT described that May cache alongside another stateless-vessel seizure assessed as moving along a route historically used to traffic weapons unlawfully to the Houthis in Yemen.

Timeline
On 27 February 2016, HMAS Darwin intercepted the dhow that produced the most specific PKM count in the open record: 49 PKM general-purpose machine guns and 39 spare barrels. CAR's later dispatch did not inspect the weapons directly but used verified photographs and described at least one Russian-manufactured PKM-pattern general-purpose machine gun from that seizure.
On 20 March 2016, FS Provence intercepted another dhow off Oman. U.S. Defense Department reporting later summarized that seizure as including six PK machine guns with bipods, while CAR described the French government destination claim as Somalia for possible transshipment to Yemen, either directly or through Eritrea, and noted that the claim had not been independently verified.
On 6-7 May 2021, USS Monterey seized a larger North Arabian Sea cache that included hundreds of PKM machine guns. The Navy's initial release said the source and intended destination were under investigation; a December 2021 NAVCENT release placed the seizure in the same enforcement pattern as stateless-vessel traffic historically used for unlawful weapons movement to the Houthis.

Narrative
The PKM/PK record in the 2014 Yemen Civil War is therefore best treated as an interdicted-supply record tied to Houthi-aligned forces, not as a quantified inventory of weapons actually fired in Yemen. The February 2016 HMAS Darwin seizure provides the most precise machine-gun count and spare-barrel count, while CAR's independent dispatch supports the PKM-pattern identification and explains the limits of the available evidence.
The destination evidence is mixed in the open sources. U.S. Navy reporting assessed the early-2016 seizure series as likely bound for Houthi insurgents in Yemen, while CAR reported Somalia-linked GPS coordinates for the HMAS Darwin dhow and a Somalia-to-Yemen transshipment theory for the FS Provence dhow. This record therefore separates the physical PKM/PK-family documentation from the assessed Houthi-bound supply route.
Within the catalog, the PKM/PK family's Yemen role is classified as interdiction and recovered materiel. That matches the public record: the sources document machine guns and PKM-pattern weapons in maritime seizure chains connected by U.S. authorities to Houthi supply, but they do not establish a named unit firing a specific PKM in a dated Yemen battle.
