Overview
Marine Unmanned Aerial Vehicle Squadron 1, commonly identified as VMU-1 and nicknamed the Watchdogs, is an active United States Marine Corps aviation unit specializing in remotely piloted and unmanned aerial operations. The squadron is based at Marine Corps Air Station Yuma, Arizona, and is assigned to Marine Aircraft Group 13 within the 3rd Marine Aircraft Wing. Its operational role is to provide reconnaissance, surveillance, target acquisition, battle-damage assessment, and related intelligence support for Marine expeditionary formations. VMU-1 traces its lineage to two remotely piloted vehicle companies activated at Marine Corps Air Ground Combat Center Twentynine Palms, California, in 1987. The units initially operated Pioneer unmanned aircraft and supported a mixture of military and domestic interagency missions. In 1990 and 1991, both companies deployed to Saudi Arabia for Operations Desert Shield and Desert Storm, where their Pioneer aircraft supported the first combat employment of the system by the United States and helped identify enemy movements, artillery, armored formations, missiles, and air-defense positions. The two companies merged in 1994 to form 1st Unmanned Aerial Vehicle Company. In 1996, that organization was redesignated VMU-1. During the 1990s and early 2000s, the squadron conducted overseas peacekeeping support in Bosnia-Herzegovina and repeated border and counter-drug missions in cooperation with United States law-enforcement agencies, the Coast Guard, and the National Park Service. VMU-1 became heavily involved in the Global War on Terror. During the 2003 invasion of Iraq, it supported the 1st Marine Division and Task Force Tarawa, conducting surveillance and helping locate targets for artillery. The squadron returned to Iraq in 2004 and played a significant intelligence and fires-support role during Operation Phantom Fury, the battle for Fallujah. A further Iraq deployment in 2005 combined Pioneer and ScanEagle aircraft and included support to Operation Steel Curtain in western Iraq. In 2007, VMU-1 became the first Marine Corps squadron to employ the RQ-7 Shadow in combat. The squadron subsequently moved through several technology generations. It began transitioning to the RQ-21A Blackjack in 2016 and operated its final Blackjack deployment with the 15th Marine Expeditionary Unit aboard USS San Diego during 2020–2021. Beginning in 2018, VMU-1 also started operating the MQ-9A Reaper under a contractor-owned, contractor-operated arrangement. In autumn 2021, it accepted its first two MQ-9A aircraft and became the Marine Corps' first operationally ready MQ-9A squadron. VMU-1 therefore represents a military operational unit rather than a consumer-facing commercial brand; its public identity is associated with Marine aviation, unmanned systems, expeditionary intelligence, and combat support.
History
VMU-1 developed from two Marine Corps remotely piloted vehicle companies activated at Twentynine Palms, California, in 1987. The 1st Remotely Piloted Vehicle Company was activated on January 21, followed by the 3rd Remotely Piloted Vehicle Company on June 24. In December 1989, both organizations were reassigned to 1st Surveillance, Reconnaissance, and Intelligence Group. The units conducted early domestic support missions as well as overseas operations. In early 1990, 1st RPV Company supported Operation Border Eagle from Texas, using Pioneer aircraft in counter-drug and immigration-enforcement work. Both companies then deployed to Saudi Arabia from September 1990 through March 1991 for Operations Desert Shield and Desert Storm. Their Pioneer aircraft provided reconnaissance of Iraqi activity and represented the Marine Corps' first combat test of the platform. On January 6, 1994, the companies merged to create 1st Unmanned Aerial Vehicle Company. On January 15, 1996, the company was redesignated Marine Unmanned Aerial Vehicle Squadron 1 and assigned to Marine Air Control Group 38. Later in 1996, VMU-1 supported NATO's Operation Joint Endeavor in Bosnia-Herzegovina, flying reconnaissance missions from the Tuzla area. Additional domestic deployments in 1998, 1999, 2001, and 2002 supported counter-drug and border-security operations along the United States-Mexico and United States-Canada borders. In February 2003, VMU-1 deployed to Kuwait and then moved toward Iraq in support of I Marine Expeditionary Force. During Operation Iraqi Freedom, it supported the 1st Marine Division and Task Force Tarawa. The squadron identified enemy artillery during the invasion, operated from multiple forward locations, and became the first Marine UAV unit to fly over Baghdad. Its 2003 deployment involved hundreds of sorties and extensive movement with advancing ground forces. The squadron returned to Iraq in 2004. Operating the Pioneer from Camp Taqaddum, it detected hostile personnel, weapons, improvised-explosive-device activity, and preparations for attacks on friendly forces. During Operation Phantom Fury in November 2004, VMU-1 flew more than 50 sorties and approximately 250 flight hours, supporting artillery adjustment, air-strike coordination, and battle-damage assessment around Fallujah. The deployment received public attention through reporting by author Bing West and later related book coverage. A third Iraq deployment began in 2005 and introduced ScanEagle alongside Pioneer. VMU-1 operated detachments at Camp Al Qaim and Camp Al Asad and supported Operation Steel Curtain in the western Euphrates River Valley. In 2007, the squadron became the first Marine Corps unit to employ the RQ-7 Shadow in combat. Administrative control transferred from Marine Air Control Group 38 to Marine Aircraft Group 13 on October 1, 2014. VMU-1 began transitioning to the RQ-21A Blackjack in 2016. It later began operating the MQ-9A Reaper in a contractor-owned, contractor-operated model in 2018. While transitioning to the Reaper, the squadron completed its final RQ-21 deployment with the 15th Marine Expeditionary Unit aboard USS San Diego; the detachment departed in October 2020 and returned in May 2021. In autumn 2021, VMU-1 received its first two MQ-9A aircraft and became the first operationally ready MQ-9A squadron in the Marine Corps.
