History
Origins during World War II
On 15 February 1944, the Squadron activated at Quantico, Virginia as Marine Observation Squadron (VMO) 5, the "Black Aces." The operational aircraft at the time was the OY-1 Piper Cub. VMO-5's primary tasks were providing aerial fire support spotting and observation in support of ground forces. Following several months of training in Camp Pendleton, California and Ewa, Hawaii, the Squadron deployed with the 3d Marine Aircraft Wing (MAW) to the Pacific Theater. It split into two groups, staging in Saipan and Guam in preparation for the Iwo Jima Campaign. On 19 February 1945, elements of the Squadron went ashore and remained on Iwo Jima until the end of the campaign. After this campaign, the Squadron redeployed to Hilo, Hawaii and attached to Marine Observation Group 1, 2d MAW. Following victory in World War II, VMO-5 deployed to Sasebo, Japan for occupation duty from September 1945 to January 1946. Upon completion of this tour, VMO-5 returned to San Diego and deactivated on 31 January 1946.

Vietnam
With the looming Vietnam War, the subunit of Headquarters and Maintenance Squadron 30 (H&MS-30) at Marine Corps Base Camp Pendleton was redesignated as VMO-5 on December 15, 1966 becoming a full-fledged training squadron. They originally fell under the command of Marine Helicopter Training Group 30 under the 3rd Marine Aircraft Wing and were equipped with a complement of UH-1E Hueys and OV-10 Broncos.[1] In March 1968, the squadron was redesignated HML-267 and remained at alert status and training replacement pilots and crew for the rest of the war. In 1971, reorganization left the squadron with only UH-1E helicopters, and by the end of 1976 only UH-1N aircraft were flown.

Post Vietnam
Every six months HML-267 rotated one-third of its assets to Marine Corps Air Station Futenma on Okinawa, Japan. The Hueys were joined by another aircraft in 1982 as the new AH-1J "Cobra"s were deployed. As part of the Unit Deployment Program (UDP) starting in 1983, HML-267 began a regular cycle of six months in Okinawa, 18 months on Camp Pendleton. During which the squadron participated in numerous training exercises including detachments to Korea, Guam, the Philippines, Hong Kong, Iwo Jima, and Australia. Redesignated HMLA-267 in 1987, the squadron received its first complement of AH-1 Cobra "SuperCobra"s. In 1988, the squadron split into three groups: A detachment on land in Okinawa, A detachment on a West Pac, and A detachment aboard USS Dubuque.

In 1990, HMLA-267 split into two groups: A detachment on land in Okinawa and another attached to HMM-164. The group attached to HMM-164 boarded USS Okinawa on a routine West Pac deployment. USS Okinawa eventually ended up in the Persian Gulf for Operation Desert Shield and Operation Desert Storm, spending a total of 354 days away from their home port for this deployment.

In 1992, HMLA-267 split into two groups: A detachment on land in Okinawa and another attached to HMM-164. The group attached to HMM-164 boarded USS Tripoli on a routine West Pac. USS Tripoli went back to the Persian Gulf for Operation Desert Sweep. The next stop for USS Tripoli was Mogadishu, Somalia and was part of the original insertion of Marines (primarily those from HMLA-267) and the beginning of Operation Restore Hope.

In January 1995 HMLA-267 embarked on LHA-3 as the ACE of SPMAGTF 1-95 to provide air support for Operation United Shield in Somalia.

Global War on Terror
In January 2003, HMLA-267 deployed aboard Amphibious Task Force West in support of Operation Iraqi Freedom. The Stingers relocated to Ali Al Salem Airbase, Kuwait February 2003 in preparation of Operation Iraqi Freedom. HMLA-267 supported the I Marine Expeditionary Force (I MEF) conducting combat operations throughout Iraq from 20 March 2003 until ordered to return to the United States in May 2003. During Operation Iraqi Freedom, the Stingers flew over 2100 combat flight hours and 1400 combat sorties in support of I MEF combat operations in just three weeks.

In June 2003, HMLA-267 participated in the Unit Deployment Program to Okinawa, Japan. During this period, the Stingers conducted exercises in South Korea, Australia and the Republic of the Philippines. From August through October 2003, the Squadron detached three UH-1N aircraft, thirteen pilots and one hundred Marines to Joint Task Force 515, in support of Operation Enduring Freedom. This detachment was selected to provide aerial escort for the President of the United States as he toured the Republic of the Philippines, the second time this HMLA has been so honored.

In October 2003, HMLA-267 was presented the John P. Giguere Award for the Marine Light Attack Helicopter Squadron of the Year for 2003.

In June 2004, a detachment of 4 AH-1W Cobras and 2 UH-1N Hueys attached to Marine Medium Helicopter Squadron 165 (REIN) on the 15th MEU. At the end of that year HMLA-267 became the sole provider of HMLA detachments to the 11th, 13th, 15th, and 31st Marine Expeditionary Units (MEU's) in support of I MEF and III MEF. While other MAG 39 squadrons continued to deploy to Iraq in support of counter-insurgency operations there, the Stingers began regularly deploying from Southern California and Okinawa to the Western Pacific and East Asia.

In April 2010, the Squadron's mission officially changed to support Operation Enduring Freedom (OEF).

In 2011 HMLA 267 deployed to Afghanistan in support of Operation Enduring Freedom.

As of April 2012, HMLA-267 transitioned completely from the AH-1W to the AH-1Z Viper, ending their decades long usage of the Whiskey. HMLA-267 was the first HMLA to completely transition to the AH-1Z and the UH-1Y.

In March 2017, HMLA-267 was presented the John P. Giguere Award for the Marine Light Attack Helicopter Squadron of the Year for 2017.
