M114 155 mm Howitzer

The M114 is a U.S.-origin 155 mm towed howitzer first fielded as the M1 during World War II and later redesignated M114. In Yemen, open-source evidence points to legacy Yemeni Army examples remaining available after the state arsenal fragmented, with Houthi-aligned forces publicly displaying M114 howitzers in 2022 rather than newly importing the system.

Open-source inventories list M114 howitzers among pre-war Yemeni Army towed artillery available to battlefield parties, and a 2022 Houthi parade in Hodeidah was identified as displaying U.S.-made 155 mm M114 howitzers; the available sources support fielding and display, not a specific firing incident.

U.S. Marine Corps F-35Cs made the variant's first documented combat strikes against Houthi targets in Yemen in 2024, and an F-35C was later reported shooting down an Iranian Shahed-139 drone near USS Abraham Lincoln in 2026.
