Korean War & the early 1960s The squadron was commissioned on 15 January 1951, at
Marine Corps Air Station El Toro,
California, as Marine Helicopter Transport Squadron 161 (
HMR-161), Air Fleet Marine Force Pacific. The squadron moved a month later to
Marine Corps Air Facility Santa Ana, California to train on their new helicopter, the
Sikorsky HRS-1. Except for the commanding officer, LtCol George Herring, most pilots in the squadron had flown fighters during
World War II. In August 1951 the squadron deployed to
South Korea and attached to the
1st Marine Aircraft Wing (1st MAW), where it operated in the central and the western fronts. of HMR-161 flying from in September 1952. HMR-161 successfully flew from the to test new concept of combining
vertical envelopment with
amphibious assault during
Operation Marlex-5 off the coast of
Inchon on 1 September 1952. While not the first ever ship to shore helicopter flight with Marines aboard, that having been done by HMR-162 during
Operation Lex Baker off the coast of Southern California in February, 1952, it was the first on foreign shores. During the course of the Korean War, HMR-161 flew 16,538 hours during 18,607 sorties eventually accounting for over 60,000 troop movements and moving 7.5 million pounds of cargo. The squadron then participated in the defense of the
Korean Demilitarized Zone (DMZ) from July 1953 to March 1955. The squadron then relocated that month to
Marine Corps Air Station Kaneohe Bay,
Hawaii, and attached to
Marine Aircraft Group 13 (MAG 13). While in Hawaii, HMR-161 was redesignated on 31 December 1956, as
Marine Helicopter Transport Squadron (Light) 161 (
HMR(L)-161), MAG 13, 1st MAW. In May 1960, the Squadron received the new Sikorsky
H-34 Seahorse. On 1 February 1962, the unit was once again re-designated as
Marine Medium Helicopter Squadron 161 (
HMM-161), MAG 13, 1st Marine Brigade. On 3 October 1962, the squadron assisted NASA by recovering astronaut
Wally Schirra and his
Project Mercury capsule
Sigma Seven out of the Pacific after a successful launch into space. During 1963,
Marine Medium Helicopter Squadron 161 (
HMM-161) assisted in several biological warfare tests conducted under
Project SHAD at
Pearl Harbor,
Kaneohe Naval Air Station and in the Pacific Ocean, near
Oahu, Hawaii. The rest of the early 1960s were spent conducting anti-guerrilla training in preparation for deployment to
South Vietnam.
Vietnam War and the 1980s during
Operation Starlite in 1965. HMM-161 departed Hawaii on 15 March 1965, on board the and arrived at
Marine Corps Air Facility Futema,
Okinawa,
Japan on 27 March. On 27 April the squadron departed Okinawa on board the headed for
South Vietnam. 6 May saw the squadron lifting elements of the
4th Marine Regiment ashore at
Chu Lai and on 15 May, the squadron began operating from the . Finally on 25 May 1965, HMM-161 came ashore at Chu Lai and was assigned under the command of
Marine Aircraft Group 16 (MAG-16), and the
1st Marine Aircraft Wing (1st MAW). On 12 June the squadron again relocated, this time to the
Phu Bai Combat Base. On 4 January 1966, HMM-161 was relieved by
HMM-163 and redeployed to
Marine Corps Air Station Futenma,
Okinawa to receive its new Vertol
CH-46 Sea Knights. During this deployment to Vietnam the squadron had one pilot awarded the
Silver Star and another eleven awarded the
Distinguished Flying Cross By April 1966, the squadron had redeployed to
Da Nang, South Vietnam with a move to Phu Bai that June. On 25 September 1966, a
UH-34D HUS from HMM-161 was struck by a friendly artillery shell while conducting a medevac mission during
Operation Prairie resulting in the death all five Marines on board. It is the only known case of friendly artillery fire shooting down an American helicopter during the war. The squadron relocated once again in November 1966 to Futenma, Okinawa, where it was attached to
Marine Aircraft Group 15 (MAG-15), 9th Marine Amphibious Brigade. A month later the squadron returned to CONUS, as they were attached to
Marine Aircraft Group 26 (MAG-26),
2d MAW at
Marine Corps Air Station New River,
North Carolina. HMM-161 then redeployed in May 1968 to
Quảng Trị Combat Base, South Vietnam and attached to provisional
Marine Aircraft Group 39 (MAG-39), 1st MAW. The Squadron finished its Vietnam years with its final deployment to Phu Bai in October 1969 while attached to MAG-16, 1st MAW. HMM-161 came home in September 1970 and attached to MAG-56,
3rd Marine Aircraft Wing, Fleet Marine Force Pacific. It was reassigned in July 1971 to MAG-16, 3d MAW. Elements of the Squadron participated in the August 1989 cleanup of the
Exxon Valdez oil spill in
Prince William Sound,
Alaska.
The Gulf War and the 1990s In 1990 they deployed on 17 August to
Saudi Arabia as part of MAG-70, 7th Marine Expeditionary Brigade in support of
Operation Desert Shield. The squadron would eventually participate in
Operation Desert Storm in Saudi Arabia and
Kuwait. In 1995, they participated in
Operation United Shield, the withdrawal of
United Nations Forces from
Somalia. By the end of the year, the unit had relocated to
MCAS El Toro,
California. In 1997, the Greyhawks deployed in March aboard the USS
Boxer to the WESTPAC and Persian Gulf as the ACE for the 15th MEU(SOC), where they flew missions in support of
Operation Southern Watch in
Iraq. In February 1999, HMM-161 moved from MCAS El Toro to
MCAS Miramar, California.
Global war on terror The new millennium began well for the Squadron, as it won the
Edward C. Dyer Marine Medium Helicopter Squadron of the Year for 2001. This followed the 2000 WESTPAC Deployment, which saw the Greyhawks provide
humanitarian assistance in
East Timor. On 6 January 2003, HMM-161 (Rein) deployed as a part of the 15th MEU for a WESTPAC Float that would end up supporting
Operation Enduring Freedom and
Operation Iraqi Freedom. The Greyhawks were assigned the mission of Tactical Recovery of Aircraft and Personnel (TRAP). Although no TRAP missions were necessary during the OIF, the Squadron did fly
Casevac and numerous other missions. The Squadron returned home to
MCAS Miramar on 12 July 2003. In November 2003, Marines of HMM-161 were told they would be redeploying to Iraq for Operation Iraqi Freedom II (OIF II). Immediate preparations were begun, and the Squadron used its December deployment to
Indian Springs, Nevada to train for the conditions that would be faced during OIF II. While at Indian Springs, the Marines of HMM-161 made their mark in Squadron history by surpassing the 40,000 mishap-free flight hours plateau. This climb into the history books began back in August 1995 and culminated with a ground crew appreciation flight over the
Hoover Dam and the
Las Vegas Strip. After receiving its cargo and aircraft at Ash Shu'aybah Port,
Kuwait, the Squadron flew up to
Al Taqaddum,
Iraq during the first week of March to set up for the relief in place with the
82nd Airborne Brigade. The Squadron made 752 consecutive mission launches in support of
I MEF operations during OIF II, logging 3072.8 hours of flight time. The Greyhawks were relieved on 1 September 2004, by HMM-268 with the main body arriving back at
MCAS Miramar on 6 September. Throughout their service during OIF II, the Greyhawks moved 116,480 pounds of cargo and 2,929 passengers, including 328 patients that needed urgent care. In August 2005, the squadron redeployed to Iraq for its third OIF deployment. The Greyhawks provided around-the-clock casualty evacuation and assault support in
Al Anbar Province. During this deployment, the squadron flew 5,199 combat flight hours, transported more than 2,100 wounded personnel and conducted 19 raids and assault support missions that led to the capture of numerous insurgents. The Greyhawks safely completing 2,999 assault support requests without mishap or damage from enemy action. On 8 February 2006, HMM-161 marked their 50,000th flight hour without a Class "A" mishap during their latest deployment to
Al Taqaddum, Iraq. During this time period, which began 19 February 1995, the squadron flew 9,100 combat hours during three combat deployments. At the completion of their deployment, HMM-161 successfully logged a record of over 58,000 class A mishap free flight hours total. This achievement is will remain intact and be unable to be surpassed by any other CH-46E squadron due to the fact the new
MV-22 Osprey will be replacing the CH-46E, and no other squadron has a record close enough to the Greyhawks' that they would be able to beat it. This milestone once again showed why the men and women of the Greyhawks are "The First, The Best". In December 2009, HMM-161 became the first of ten west coast squadrons to transition to the MV-22 Osprey and was redesignated as Marine Medium Tiltrotor Squadron 161 during the change of command. VMM-161 completed its operational training requirements to the MV-22 Osprey and became a fully capable, combat ready tiltrotor squadron in April 2011. Shortly thereafter, in July 2012, the Greyhawks deployed to Afghanistan to support Operation Enduring Freedom as the first combat deployment for the MV-22. The squadron completed the deployment and subsequently returned safely to MCAS Miramar in January 2013, having flown more than 2,200 hours, supporting more than 100 named operations, and suffering zero mishaps. ==See also==
