MARINE MEDIUM TILTROTOR SQUADRON 164 (VMM-164)
Marine Medium Helicopter Squadron 164 (HMM-164) was activated under LtCol Herbert J Blaha on 1 Jul 1964, at Marine Corps Air Station Santa Ana, California as part of Marine Aircraft Group 36. In Aug 1965 the squadron transferred to Marine Wing Support Group 37 at Marine Corps Air Station El Toro, California. The squadron received the first CH-46 Sea Knights assigned to West Coast duty six months after activation.
HMM-164 brought the first CH-46 Sea Knight helicopters into Vietnam when they landed at Marble Mountain Air Facility after transiting from the USS Valley Forge (LPH-8) in Mar 1966. HMM-164 remained in Vietnam for a three and one-half years as part of Marine Aircraft Group 16 (MAG-16). During their time in country they operated in and around the following areas: Quảng Trị, Đông Hà, Khe Sanh, Huế, Phu Bai and off the decks of the USS Princeton (LPH-5), the USS Tripoli (LPH-10) and the Valley Forge. While in Vietnam, HMM-164 supported US forces in all the major operations, most notably in Operation Hastings and Operation Meade River. On 15 Jul 1966, while conducting the initial insertion of ground forces during Operation Hastings the squadron lost three CH-46A Sea Knights in the vicinity of LZ Crow near Con Thien. Two aircraft crashed when their rotorblades intermeshed while trying to avoid Marines on the ground and the third crash was caused by heavy ground fire.
In Oct 1969, the squadron left South Vietnam and relocated to Okinawa, Japan where it joined Marine Aircraft Group 15 (MAG-15). From Oct 1969 through Apr 1972, it deployed with elements of the United States Seventh Fleet as part of a special landing force. HMM-164 supported combat and search and rescue operations off the coast of Vietnam until Apr 1972 when it deployed aboard the USS Okinawa. While aboard the Okinawa, HMM-164 continued to provide Joint Service combat support in Operation Song Than and Operation Lam Son 719 until returning to Marine Corps Air Station Futenma, Okinawa in 1973.
After the withdrawal of American forces from Vietnam and the squadron’s subsequent transfer to Marine Aircraft Group 39 (MAG 36), HMM-164 participated in numerous peacetime operations aboard naval shipping traveling to Korea, the Republic of the Philippines, and Japan as well as many exercises in Okinawa.
A detachment from the squadron participated in the evacuation of Americans from Phnom Penh, Cambodia, on 12 Apr 1975, as part of Operation Eagle Pull. On 30 Apr 1975, an HMM-164 CH-46D crew lifted the last Americans out of Vietnam when they picked up the Marine combined security force during Operation Frequent Wind.
With the advent of the Unit Deployment Program, on 1 Sep 1978, HMM-164 returned home to MCAS Santa Ana, CA. In Sep 1978, the squadron rejoined Marine Aircraft Group 36 (MAG-36) at MCAS(H) Futenma for a six-month tour beginning in August 1979 and returning to MCAS(H) Tustin in Feb 1980. On 1 Nov 1980, HMM-164 became the first unit on the West Coast to receive the “E” model CH-46. By Mar 1981, the squadron had received its full complement of “Echo” helicopters. During the summer of 1989, the squadron simultaneously supported oil spill cleanup efforts in Valdez, Alaska and an Air Contingency Force at Soto Cano AB, Honduras.
In Jun 1990, HMM-164 deployed to the Western Pacific with the 13th Marine Expeditionary Unit (13th MEU) and provided support relief efforts following the July earthquake that devastated the Philippines. In Aug 1990 the squadron proceeded to Southwest Asia and participated in maritime interdiction operations during Operation Desert Shield and then provided combat support during Operation Desert Storm before returning to MCAS Tustin in Apr 1991.
The squadron deployed in Oct 1992 with the 15th Marine Expeditionary Unit (15th MEU). The squadron provided support to Joint Task Force (Somalia) during Operation Restore Hope from Dec 1992 until Feb 1993. HMM-164 returned to MCAS Tustin in Apr 1993. Aug 1993 found the squadron providing support for units training at the Mountain Warfare Training Center, Bridgeport, CA and provided a mission capabilities demonstration for the Secretary of the Navy. In Aug 1993, the Marine Corps Aviation Association chose HMM-164 as the Medium Helicopter Squadron of the year.
In Jun 1995, HMM-164 deployed as the Aviation Combat Element with the 11th Marine Expeditionary Unit (11th MEU). During this time it provided support for the United States Central Command in Operation Vigilant Sentinel in Kuwait as well as Bahrain, Qatar, and United Arab Emirates before returning and relocating to MCAS El Toro, California in Dec 1995.
In Feb 1996, HMM-164 was called upon to support the President of the United States as he visited the flood-ravaged areas around Portland, Oregon.
On 28 Aug 1997, HMM-164 (REIN) deployed again with the 13th Marine Expeditionary Unit. During the month of Dec 1997-Jan 1998, the squadron’s AV-8B Harrier IIs and KC-130 Hercules flew combat sorties in support of Operation Southern Watch over southern Iraq. HMM-164 (REIN) returned to MCAS El Toro on 26 Feb 1998, completing its final deployment before re-designation as a Fleet Replacement Squadron.
On 8 Jan 1999, HMM-164 relocated to MCAS Camp Pendleton, California as part of the Base Realignment and Closure (BRAC) move and was attached to MAG-39 effective 11 Jan. In Feb 1999, the Squadron was re-designated HMMT-164 and was tasked to become the Marine Corps’ Fleet Replacement Squadron for the CH-46E.
During Mar 1999, the squadron deployed two aircraft to Moffett Federal Airfield to support Operation Urban Warrior and accept its first two student pilots. In May, the Marine Enlisted Aircrew Training Department accepted its first class of new enlisted aircrew. On 1 Jun 1999, the squadron took over the role as Model Manager and Fleet Project Team Manager for the CH-46E. Since 2000, HMMT-164 has trained over 360 new pilots and 460 crew chiefs.
On 28 Jun 2008, HMMT-164 deployed to Naval Air Station Lemoore after California Governor Arnold Schwarzenegger requested military assistance to fight raging wildfires. The helicopters are providing medium lift rotary wing support to United States Northern Command and the National Fire Center.
On 9 Apr 2015, HMMT-164 officially retired the CH-46E and transitioned to the MV-22B Osprey. As part of the transition, they became a fleet squadron rather than a training squadron and so were redesignated as VMM-164.
In the spring of 2018, VMM-164 deployed for the first time as an MV-22B Osprey squadron in support of Operation Inherent Resolve. They serve as one of the main means of transportation of VIPs, troops and cargo in the Area of Operations.
